One of the earliest methods of thrust vectoring in rocket engines was to place vanes in the engine's exhaust stream. These exhaust vanes or jet vanes allow the thrust to be deflected without moving any parts of the engine, but reduce the rocket's efficiency. They have the benefit of allowing roll control with only a single engine, which nozzle gimbaling does not. The V-2 used graphite exhaust vanes and aerodynamic vanes, as did the Redstone, derived from the V-2.

The Sapphire and Nexo rockets of the amateur group Copenhagen Suborbitals provide a modern example of jet vanes. Jet vanes must be made of a refractory material or actively cooled to prevent them from melting. Sapphire used solid copper vanes for copper's high heat capacity and thermal conductivity, and Nexo used graphite for its high melting point, but unless actively cooled, jet vanes will undergo significant erosion. This, combined with jet vanes' inefficiency, mostly precludes their use in new rockets.

Air escapes to the back of the impeller and a special expeller discharges the air back to the suction tank. The impeller may also feature special small vanes between the primary vanes called split vanes or secondary vanes. Some pumps may feature a large eye, an inducer or recirculation of pressurized froth from the pump discharge back to the suction to break the bubbles.

Apart from the first stage nozzle guide vanes, the LP turbine was completely statorless, with four consecutive rotor stages. Rotors one and three drove the front fan clockwise (viewed from the front), whereas the rear fan was driven anticlockwise by rotors two and four. Although the front fan had inlet guide vanes, there were no vanes between the contra-rotating fan rotors or, downstream, any exit guide vanes. The core and bypass streams exhausted through separate coaxial propelling nozzles.

Angle of vanes vary throughout the range of RPM to optimize turbine behaviour. At high engine speed, vanes are fully open and the exhaust is fully directed onto the turbine blades. At low engine speeds vanes are almost closed creating a narrow passage for the exhaust. This accelerates the exhaust towards the turbine blades, making them spin faster.
|

In the same round, Vanes trapped Román against the ropes and knocked him down. After Román got up, Vanes landed a hard right hook on his chin and followed up with a barrage of blows while Román was leaning on the ropes, causing the fight to be stopped and turning what seemed to be near- defeat into victory. On October 29, 2011 Vanes fought contender Richard Gutierrez. Vanes dominated from start to finish and won a ten round unanimous decision.

Pennaceous feathers have a rachis with vanes or vaxillum spreading to either side. These vanes are composed of a high number of flattened barbs, that are connected to one another with barbules. The barbules are tiny strands that criss-cross on the flattened sides of the barbs. This forms a miniature velcro-like mesh that holds all the barbs together, stabilizing the vanes.

Smaller, similar structures are often situated further forward, between the front wheels and the monocoque. These are typically called "turning vanes" rather than bargeboards, and are used in addition to, or sometimes in place of full bargeboards, depending on the aerodynamic approach of the car. Initially relatively simple in their design, bargeboards and turning vanes became progressively more complex through the 2000s, integrating with the floor, mirror supports, suspension mounts, and other structures in more elaborate ways. See HVAC turning vanes for turning vanes used inside of ductwork.

The rotor contains a number of sliding vanes, typically six. As the rotor is rotated, the vanes are held against the walls of the cylindrical body. Entry and exit ports at the top and bottom of the cylinder, where the rotor is furthest from and nearest to the wall, provide a vacuum pumping effect. The vanes are held against the cylinder by an internal cam ring or by springs.

An open impeller has a hub with attached vanes and is mounted on a shaft. The vanes do not have a wall, making open impellers slightly weaker than closed or semi-closed impellers. However, as the side plate is not fixed to the inlet side of the vane, the blade stresses are significantly lower. In pumps, the fluid enters the impeller's eye, where vanes add energy and direct it to the nozzle discharge.
|

If the hydraulic pump or hydraulic motor makes use of the hydrodynamic effects of the fluid flow, i.e. pressure due to a change in the fluid's momentum as it flows through vanes in a turbine. The pump and motor usually consist of rotating vanes without seals and are typically placed in proximity. The transmission ratio can be made to vary by means of additional rotating vanes, an effect similar to varying the pitch of an airplane propeller.
|
|
The static structure of the engine over this length is a large diameter tube within the turbine. In most designs, two contra-rotating rings of turbine and propeller are used. Intermeshed contra-rotating turbines can act as the guide vanes for each other, removing the need for static vanes.

Too recent to cover the entire relevant time frame in the data above, on June 15, 2006 Unit 5 was shut down due to excessive turbine vibrations. It was discovered that a number of turbine vanes had actually completely broken off. In the turbine that failed, nearly all vanes showed fractures or cracking while the majority of the vanes of the other two low pressure turbines also showed problems. Fault for the problems was placed on Hitachi, the NSSS supplier.

Branches are generally shortest near the outer tip of the vanes, growing gradually longer near the center where the longest branches usually occur. Depending on the number, the vanes display pentaradiate, tetra radiate, or biradiate symmetries. The vanes give C. lyra its harp-like structure and these are covered in velcro-like hooks and spines, which it uses to snare prey that drift past it in currents. Of the specimens found, the largest recorded is nearly 60 centimeters in length.

The two most common implementations of VGTs are as follows: For light-duty engines (passenger cars, race cars, and light commercial vehicles), the turbine's vanes rotate in unison, relative to its hub, to vary its pitch and cross- sectional area. For heavy-duty engines, the vanes do not rotate, but instead, their effective width is changed. This is usually done by moving the turbine along its axis, partially retracting the vanes within the housing. Alternatively, a partition within the housing may slide back and forth.

A panemone WEH with 8 airfoils The vanes of a panemone are moved by the wind in a circle to turn the drive shaft. To accomplish this they must move with the wind only while on one side of the circle, and move against the wind on the other side. To prevent the vanes moving upwind from being blown back by the wind, one half of the panemone may be shielded, or else the vanes may be attached so that they can turn edge-on to the wind when the wheel is moving them upwind.

This is accomplished by reducing the area above the ocean surface to small floats and an antenna. Below the surface is a series of drogue vanes to 70 cm. (less than the 1 m Davis-style buoy) in depth, which catch the ocean current, along with electronic equipment that deploys the vanes and antenna, receives the GPS signal and transmits the location to the USCG. SLDMB construction varies by manufacturer, but those used by the USCG consists of four orthogonal drag vanes 0.5m wide and 0.7m high of nylon fabric.
|
|
The Vickers design included an elliptic chamber which confined the radial motion of the vanes nested in the rotor slots. As the rotor and vanes turn, each vane is first pushed radially inward followed by a maximum radial extension and that happens twice per revolution. The displacement of the fixed device is calculated by determining the difference in vane extension between minimum and maximum, times the axial length of the vanes and rotor. This multiplies to an area subject to the hydraulic pressure in the device whether used as a motor or a pump.

A supersonic flow can turn very sharp angles, since nature provides expansion fans that do not exist in subsonic flows. To avoid separation in subsonic nozzles, the expansion angle should not exceed 10°. For larger angles, vanes are used so that the angle between the vanes does not exceed 10°.

In other words, as the vanes rotate through the sealing area, for a small amount of rotation, both adjacent vanes are within the sealing area. As the rotation continues, the first vane in line leaves the sealing area, but not before the next vane in succession is firmly in the sealing region. The effect is to prevent the exchange of oil from any two adjacent chambers located on either side of a given sealing area and the oil can only be interchanged by the actual rotation of the rotor and vanes. This is the pumping mechanism for the historical vane pump or motor.

With the occasional, and usually tenuous, exception of the Wankel engine. This is however a pistonless rotary engine without being a cam engine. Most pistonless engines relying on cams, such as the Rand cam engine, use the cam mechanism to control the motion of sealing vanes. Combustion pressure against these vanes causes a vane carrier, separate from the cam, to rotate.

In the second half of the nineteenth century, manufacturers began to sell commercially produced, copper weathervanes. Makers of these vanes would hammer copper sheeting into cast-iron molds copied from carved-wood patterns. Using a mold enabled manufacturers to reproduce each design many times. Shelburne's collection includes finished copper vanes, cast-iron molds, and a unique wooden pattern for a Lady Liberty weathervane.

A Crookes radiometer in action The radiometer is made from a glass bulb from which much of the air has been removed to form a partial vacuum. Inside the bulb, on a low friction spindle, is a rotor with several (usually four) vertical lightweight vanes spaced equally around the axis. The vanes are polished or white on one side and black on the other. When exposed to sunlight, artificial light, or infrared radiation (even the heat of a hand nearby can be enough), the vanes turn with no apparent motive power, the dark sides retreating from the radiation source and the light sides advancing.
|
|
The details of exactly how this moves the warmer side of the vane forward are given in the section below. The internal temperature rises as the black vanes impart heat to the air molecules, but the molecules are cooled again when they touch the bulb's glass surface, which is at ambient temperature. This heat loss through the glass keeps the internal bulb temperature steady with the result that the two sides of the vanes develop a temperature difference. The white or silver side of the vanes are slightly warmer than the internal air temperature but cooler than the black side, as some heat conducts through the vane from the black side.

The barrel may also have vanes, typically made of rubber, which run along the inside of the barrel. As the barrel turns the vanes catch and lift the parts, which eventually slide down or fall. In a wet processes a compound, lubricant, or barreling soap is added to aid the finishing process, prevent rusting, and to clean parts. A wide variety of media is available to achieve the desired finished product.

Hydraulic retarders use the viscous drag forces between dynamic and static vanes in a fluid-filled chamber to achieve retardation. There are several different types which can use standard transmission fluid (gear oil), a separate oil supply, water, or a mix of oil and magnetic retardation. Magnetic retarders are similar to the electric retarder discussed below. A simple retarder uses vanes attached to a transmission driveshaft between the clutch and roadwheels.

The cylindrical casings are open at each end with a larger opening facing the wind. The wind catches a number of wheels and feathered vanes fixed to a shaft revolving in bearings inside the casings. When the wind has passed between the vanes of the front wheel it is directed by the guide vanes to the second wheel and is again taken up by guides and passed to a third wheel and so on, the action each time increasing the effect of the wind on the shaft and improving efficiency. The Clarkson of which an illustration survives (1919) was erected by the Air Power Co. of Prestwich, Cheshire on the estate of Lord Derby.

Guide and stay vanes: The primary function of the guide and stay vanes is to convert the pressure energy of the fluid into kinetic energy. It also serves to direct the flow at design angles to the runner blades. Runner blades: Runner blades are the heart of any turbine. These are the centers where the fluid strikes and the tangential force of the impact causes the shaft of the turbine to rotate, producing torque.

Prior to launch, the missile was referenced in azimuth by its gyrocompass inertial platform. After launch, the missile followed an inertially guided trajectory until RV separation. Attitude and guidance commands during powered flight (except for roll attitude) were executed via the swivel nozzles in the two propulsion sections. Roll control was provided by two movable air vanes on the first stage during first stage flight and by the RV air vanes during second stage flight.

There are two scales for use with two different sizes of vane – vanes are used for soils with shear strengths up to 50 kN/m2 and vanes for stronger soils. In the United Kingdom the methodology is governed by British Standard 1377 (Methods of test for soils for civil engineering purposes). The shear vane is a simple and portable piece of equipment. The test is suitable for clay soils classified as soft to firm.

The M139 was a spherical bomblet that was filled with of sarin (GB). On the outside of the device were "vanes"; the vanes created a spin which armed the impact fuze. This "spin-to-arm" type fuze required between 1,000 and 2,000 rotations per minute to arm, which made handling the bomblets simpler because they were insensitive to normal movements.Mauroni, Albert J. Chemical Demilitarization: Public Policy Aspects, (Google Books), Greenwood Publishing Group, 2003, p.

Taildog was highly manoeuvrable through the use of thrust vectoring for all flight control. Vectoring was accomplished by rotating small vanes into the rocket exhaust. Six of these vanes were arranged as segments of a circle at the tail end of the missile body, where they were protected from the rocket exhaust. Each segment was pivoted at one end, allowing it to be rotated so the other end would be moved into the exhaust.

Centrifugal pumps are the machines, which employ centrifugal force to lift liquids from a lower level to a higher level by developing pressure. A simplest type of pump comprises an impeller fitted onto a shaft, rotating in a volute casing. Liquid is led into the centre of the impeller (known as 'eye' of the impeller), and is picked up by the vanes of the impeller and accelerated to a high velocity by the vanes of the impeller, and discharged by the centrifugal force into the casing and then out the discharge pipe. When liquid is forced away from the centre, a vacuum is created and more liquid receives energy from the vanes and gains in pressure energy and kinetic energy.

The two sides of each vane must be thermally insulated to some degree so that the polished or white side does not immediately reach the temperature of the black side. If the vanes are made of metal, then the black or white paint can be the insulation. The glass stays much closer to ambient temperature than the temperature reached by the black side of the vanes. The external air helps conduct heat away from the glass.

The color triangle formed by velocity vector u,c,w called "velocity triangle". This rule was helpful to detail Eq.(1) become Eq.(2) and wide explained how the pump works. Fig 2.3 (a) shows triangle velocity of forward curved vanes impeller ; Fig 2.3 (b) shows triangle velocity of radial straight vanes impeller. It illustrates rather clearly energy added to the flow (shown in vector c) inversely change upon flow rate Q (shown in vector cm).

On selection, the system folds the doors to block off the cold stream final nozzle and redirect this airflow to the cascade vanes. This system can redirect both the exhaust flow of the fan and of the core. The cold stream system is known for structural integrity, reliability, and versatility. During thrust reverser activation, a sleeve mounted around the perimeter of the aircraft engine nacelle moves aft to expose cascade vanes which act to redirect the engine fan flow.

The columns are made of stainless steel. Conical vanes are attached alternately to the wall of the column and to a central rotating shaft. The product is poured in at the top under vacuum, and steam is pumped into the column from below. The vanes provide a large surface area over which volatile compounds can evaporate into the steam, and the rotation ensures a thin layer of the product is constantly moved over the moving cone.

The exterior stonework has been covered over by many layers of white paint, giving a look of an almost harled coating. There are three interesting and delicately designed weather vanes atop the church, one at the apex of each of the vaulted circular towers, but each at a different height. On one of the vanes are the initials P.B.B. (Preben Bille Brahe) to denote the association of the Brahe family of Hvedholm. The church tower bells are dated to 1568 and 1613.

A single-phase polarizing winding is connected to the "running" system. It is mounted perpendicular to the field winding and produces a magnetic flux that passes through the moving vanes. The moving vanes turn a shaft that carries a pointer moving over a scale. If the frequency of the source connected to the polarizing winding is different from the source connected to the field winding, the pointer rotates continually at a speed proportional to the difference in system frequencies (the beat frequency).

The B-1's variable-sweep wings and thrust-to-weight ratio provide it with improved takeoff performance, allowing it to use shorter runways than previous bombers. The length of the aircraft presented a flexing problem due to air turbulence at low altitude. To alleviate this, Rockwell included small triangular fin control surfaces or vanes near the nose on the B-1. The B-1's Structural Mode Control System rotates the vanes automatically to counteract turbulence and smooth out the ride.

Vertically mounted tubes of up to 1-metre diameter extending from just above the base of a deep concrete tank to just below the surface of the sewage liquor. A typical shaft might be 10 metres high. At the surface end, the tube is formed into a cone with helical vanes attached to the inner surface. When the tube is rotated, the vanes spin liquor up and out of the cones drawing new sewage liquor from the base of the tank.

Based on the archaeological evidence provided by pottery models of the winnowing machine, the winnowing machine was constructed within the courtyard wall that had querns and trip hammers placed near it. The machine also had a crank operated rotary fan with four blades, an air inlet, and hopper as well as a box, crank, and vanes. The device was able to operated by hands or feet. The crank consists of four to six vanes that are made of thin boards.

The F119 has dual- redundant full authority digital engine control (FADEC). The three-zone afterburner, or augmentor, contributes to the stealth of the aircraft by having fuel injectors integrated into thick curved vanes coated with ceramic radar-absorbent materials (RAM). These vanes replace the traditional fuel spray bars and flame holders and block line-of-sight of the turbines. The nozzle can vector ±20° in the pitch axis to improve aircraft maneuverability and consists two wedge-shaped flaps for stealth.

Garrett variable-geometry turbocharger on DV6TED4 engine Variable-geometry or variable-nozzle turbochargers use moveable vanes to adjust the air-flow to the turbine, imitating a turbocharger of the optimal size throughout the power curve. The vanes are placed just in front of the turbine like a set of slightly overlapping walls. Their angle is adjusted by an actuator to block or increase air flow to the turbine. This variability maintains a comparable exhaust velocity and back pressure throughout the engine's rev range.

Close-up bow view of the gondola in 1906 Directional stability was achieved by four fixed vanes, two vertical and two horizontal, attached at the rear of the gas-bag, and by a long vertical vane running along the main axis of the gas-bag from the centre of the elliptical frame to its rear. Horizontal motion was controlled by the movement of a balanced rudder at the rear of an empennage on a long boom, mounted below the gas-bag and aft of the gondola (see lead image). The empennage consisted of vertical and horizontal vanes arranged like the fletching of an arrow, behind which the vertical rudder was mounted. During a refit in 1907 the vertical vanes of the empennage were modified, as is shown in the accompanying illustration.

The rotating airfoils, also known as blades or rotors, accelerate the fluid. The stationary airfoils, also known as stators or vanes, decelerate and redirect the flow direction of the fluid, preparing it for the rotor blades of the next stage. Axial compressors are almost always multi-staged, with the cross-sectional area of the gas passage diminishing along the compressor to maintain an optimum axial Mach number. Beyond about 5 stages or a 4:1 design pressure ratio a compressor will not function unless fitted with features such as stationary vanes with variable angles (known as variable inlet guide vanes and variable stators), the ability to allow some air to escape part-way along the compressor (known as interstage bleed) and being split into more than one rotating assembly (known as twin spools, for example).

As a vane moves into, say, a maximum extension, and then rotates into a minimum extension region of the cam ring, it passes through a gradual transition from maximum to minimum followed by a gradual transition back to maximum and this happens twice per revolution. In order to prevent oil under pressure from bypassing the vanes, 4 sealing areas are created by means of 4 kidney shaped ports located in the transition areas between minimum and maximum. The spaces between the kidney ports are called the sealing areas and this port system is located at either, or both axial ends of the rotor and vanes. The configuration of the ports and sealing areas are such that the space between any two adjacent vanes is slightly less than the coverage of the sealing area.

It stays on wing 20% longer, uses 30% fewer parts to lower maintenance costs and has a contra-rotating architecture. The Lean combustor reduces NOx gases with required pressure loss and backflow margin. Fan blades have steel alloy leading edges and the composite fan case reduces thermal expansion. To reduce fuel burn, the 23:1 pressure ratio high-pressure compressor is based on the GE90-94B, shrouded guide vanes reduce secondary flows and counter-rotating spools for the reaction turbines reduce load on guide vanes.

When the aircraft speed is 7% above stall, the stall warning energizes a control column shaker that produces a low-frequency buffet signal through the control column to warn the crew. When both angle-of-attack transducer vanes increase to 5% above stall, the pitch servo commands an aircraft nose down attitude. The force applied in the nose down direction is 80 pounds at the control wheel. When the angle-of-attack transducer vanes decrease below the stall point, the nose down command is removed.

Wraps are thin pre-cut sheets of material, often vinyl or plastic, used to wrap the nock end of an arrow, primarily as an aid in bonding vanes and feather fletchings to the shaft. Wraps can also make the eventual removal of vanes and vane-glue easier. Additionally, they add a decorative aspect to arrow building, which can provide archers an opportunity to personalize their arrows. Brightly colored wraps can also make arrows much easier to find in the brush, and to see in downrange targets.

Anatomical illustration comparing the "frond-tail" of Archaeopteryx with the "fan-tail" of a modern bird Specimens of Archaeopteryx were most notable for their well-developed flight feathers. They were markedly asymmetrical and showed the structure of flight feathers in modern birds, with vanes given stability by a barb-barbule-barbicel arrangement. The tail feathers were less asymmetrical, again in line with the situation in modern birds and also had firm vanes. The thumb did not yet bear a separately movable tuft of stiff feathers.

Cross section of M712 Copperhead Copperhead has two modes of operation: Ballistic mode and glide mode. Ballistic mode is used where the cloud ceiling is high and visibility is good. When the projectile is 3,000 meters from the target, the guidance vanes extend, the target is acquired, and then the on-board guidance system adjusts the guidance vanes to maneuver onto the target. Glide mode is used when the cloud ceiling and/or the visibility is too low to permit the use of the ballistic mode.

The liquid-ring pump compresses gas by rotating a vaned impeller located eccentrically within a cylindrical casing. Liquid (usually water) is fed into the pump and, by centrifugal acceleration, forms a moving cylindrical ring against the inside of the casing. This liquid ring creates a series of seals in the space between the impeller vanes, which form compression chambers. The eccentricity between the impeller's axis of rotation and the casing geometric axis results in a cyclic variation of the volume enclosed by the vanes and the ring.

A second stationary field coil, perpendicular to the voltage coils, carries a current proportional to current in one phase of the circuit. The moving system of the instrument consists of two vanes that are magnetized by the current coil. In operation the moving vanes take up a physical angle equivalent to the electrical angle between the voltage source and the current source. This type of instrument can be made to register for currents in both directions, giving a four-quadrant display of power factor or phase angle.

When the radiometer is heated in the absence of a light source, it turns in the forward direction (i.e. black sides trailing). If a person's hands are placed around the glass without touching it, the vanes will turn slowly or not at all, but if the glass is touched to warm it quickly, they will turn more noticeably. Directly heated glass gives off enough infrared radiation to turn the vanes, but glass blocks much of the far-infrared radiation from a source of warmth not in contact with it.

Years after this explanation was dismissed, Albert Einstein showed that the two pressures do not cancel out exactly at the edges of the vanes because of the temperature difference there. The force predicted by Einstein would be enough to move the vanes, but not fast enough. #The final piece of the puzzle, thermal transpiration, was theorized by Osborne Reynolds; Part 2. in an unpublished paper of 1879 that was refereed by Maxwell, who then published his paper which contained a critique of the mathematics in Reynolds's unpublished paper.

It had four combustion chambers, reached a height of 200 feet, and corrected its vertical path using blast vanes until one chamber burned through. This flight demonstrated that a rocket with multiple combustion chambers could fly stably and be easily guided. In July 1937 he replaced the guidance vanes with a movable tail section containing a single combustion chamber, as if on gimbals (thrust vectoring). The flight was of low altitude, but a large disturbance, probably caused by a change in the wind velocity, was corrected back to vertical.

The regulator measures the speed and then regulates the flow of water to the turbine in order to adapt the output to the water supply. In island operation mode it maintains the main frequency of 50 Hz. Art Deco-style switching wall The water supply can be regulated by means of the guide vane, which is arranged around the turbine and consists of adjustable vanes. The water flows through the guide vanes onto the blades of the approx. 62 kW (84 hp) Francis turbine built by the Maschinenfabrik Bell and sets them in rotation.

In the words of historian Alex Keller, his machines "look like armchair inventions which seldom ever had any three- dimensional working counterparts". Branca's so-called steam engine appears as the 25th plate in Le Machine. It comprises a wheel with flat vanes like a paddlewheel, shown being rotated by steam produced in a closed vessel and directed at the vanes through a pipe (and hence would be more appropriately called a steam turbine). Branca suggested that it might be used for powering pestles and mortars, grinding machines, raising water, and sawing wood.

An axial turbine is a turbine in which the flow of the working fluid is parallel to the shaft, as opposed to radial turbines, where the fluid runs around a shaft, as in a watermill. An axial turbine has a similar construction as an axial compressor, but it operates in the reverse, converting flow of the fluid into rotating mechanical energy. A set of static guide vanes or nozzle vanes accelerates and adds swirl to the fluid and directs it to the next row of turbine blades mounted on a turbine rotor.

Fletchings are traditionally made from feathers (often from a goose or turkey) bound to the arrow's shaft, but are now often made of plastic (known as "vanes"). Historically, some arrows used for the proofing of armour used copper vanes. Flight archers may use razor blades for fletching, in order to reduce air resistance. With conventional three-feather fletching, one feather, called the "cock" feather, is at a right angle to the nock, and is normally nocked so that it will not contact the bow when the arrow is shot.

This type of meter responds to both direct and alternating currents (as opposed to the moving- coil ammeter, which works on direct current only). The iron element consists of a moving vane attached to a pointer, and a fixed vane, surrounded by a coil. As alternating or direct current flows through the coil and induces a magnetic field in both vanes, the vanes repel each other and the moving vane deflects against the restoring force provided by fine helical springs. The deflection of a moving iron meter is proportional to the square of the current.

Air is pumped through the motor input which pushes on the vanes creating the rotational motion of the central shaft. Rotation speeds can vary between 100 and 25,000 rpm depending on several factors which include the amount of air pressure at the motor inlet and the diameter of the housing. One application for vane-type air motors is to start large industrial diesel or natural gas engines. Stored energy in the form of compressed air, nitrogen or natural gas enters the sealed motor chamber and exerts pressure against the vanes of a rotor.

Skeletal restoration E. hui is known from a well-preserved partial skeleton that includes four long feathers on the tail, composed of a central rachis and vanes. However, unlike in modern-style rectrices (tail feathers), the vanes were not branched into individual filaments but made up of a single ribbon- like sheet. Epidexipteryx also preserved a covering of simpler body feathers, composed of parallel barbs as in more primitive feathered dinosaurs. However, the body feathers of Epidexipteryx are unique in that some appear to arise from a "membranous structure" at the base of each feather.

Along with the wing, active cooling vanes at the rear are used which are activated by a smart material that reacts to heat. When a certain temperature is reached, the vanes rotate for extra airflow. The interior is based heavily on the Aventador's interior, but the centre console has been tidied up and a portrait touchscreen first seen in the Huracán Evo is one of the key differences. The leather upholstery has been done by Poltrona Frau, an Italian furniture company and 3D printed parts are used on the interior for the first time.

The pastors who served the Peta Chapel were Robert William Faradize, Abijah Samuel, Josiah Hudson, J A Vanes and T Luke. Of these Josiah Hudson was a prominent Weslyan pastor, who has local pastors Samuel Abijah and T Luke serving under him. By 1904, the small chapel could not accommodate its 250 members and hence a need rose to build a new bigger church. In 1900, Rev J A Vanes, a Wesleyan missionary of the purchased the present church land, and a new stone church building was constructed and named after Rev.

Air resistance models use vanes on the flywheel to provide the flywheel braking needed to generate resistance. As the flywheel is spun faster, the air resistance increases. An adjustable vent can be used to control the volume of air moved by the vanes of the rotating flywheel, therefore a larger vent opening results in a higher resistance, and a smaller vent opening results in a lower resistance. The energy dissipated can be accurately calculated given the known moment of inertia of the flywheel and a tachometer to measure the deceleration of the flywheel.

The single-engine aircraft is powered by the Pratt & Whitney F135 low-bypass augmented turbofan with rated thrust of . Derived from the Pratt & Whitney F119 used by the F-22, the F135 has a larger fan and higher bypass ratio to increase subsonic fuel efficiency, and unlike the F119, is not optimized for supercruise."Frequently Asked Questions about JSF" . JSF. Retrieved 6 April 2010. The engine contributes to the F-35's stealth by having a low-observable augmenter, or afterburner, that incorporates fuel injectors into thick curved vanes; these vanes are covered by ceramic radar-absorbent materials and mask the turbine.

Animated image showing the operation of a flexible–impeller pump A flexible impeller pump is a positive-displacement pump that, by deforming impeller vanes, draws the liquid into the pump housing and moves it to the discharge port with a constant flow rate. The flexibility of the vanes enables a tight seal to the internal housing, making the pump self-priming, while also permitting bi-directional operation. The output from these pumps tends to be smooth or gentle when compared to the operation of a reciprocating pump (for example). In 1938, Arthur M. Briggs filed a patent for this type of pump.

The rate of spin was varied by a programmer so that it did not couple with the changing resonance frequency of the first stage during flight. The upper-stage tub was visibly spun-up before launch. During first- stage flight, the vehicle was guided by a gyro-controlled autopilot controlling both air-vanes and jet vanes on the first stage by means of servos. Following a vertical launch from a simple steel table, the vehicle was programmed so that it was traveling at an angle of 40 degrees from the horizontal at burnout of the first stage, which occurred 157 seconds after launch.

In the Alliance-Union universe faster-than-light (FTL) ships have two major drive systems, slower-than-light (STL) thrusters and FTL jump engines. The jump engines comprise vanes that are attached to the outside of the ship. When the vanes are pulsed, they generate gravity waves which create a field, or "bubble", around the ship that pulls it (and anything else in the field) along the interface between realspace (Einsteinian space) and hyperspace (jumpspace). Jump takes place between two massive objects, called jump-points, which are generally stars, brown dwarves, or "rogue planets" sufficiently massive to make "pockmarks" in hyperspace.

Some arrows may simply use a sharpened tip of the solid shaft, but separate arrowheads are far more common, usually made from metal, stone, or other hard materials. The most commonly used forms are target points, field points, and broadheads, although there are also other types, such as bodkin, judo, and blunt heads. Shield cut straight fletching – here the hen feathers are barred red Fletching is traditionally made from bird feathers, but solid plastic vanes and thin sheet-like spin vanes are used. They are attached near the nock (rear) end of the arrow with thin double sided tape, glue, or, traditionally, sinew.

The vanes of each feather have hooklets called barbules that zip the vanes of individual feathers together, giving the feathers the strength needed to hold the airfoil (these are often lost in flightless birds). The barbules maintain the shape and function of the feather. Each feather has a major (greater) side and a minor (lesser) side, meaning that the shaft or rachis does not run down the center of the feather. Rather it runs longitudinally of center with the lesser or minor side to the front and the greater or major side to the rear of the feather.

In a swashplate engine the piston rods stay parallel with the shaft, and piston side-forces that cause excessive wear can be eliminated almost completely. The small-end bearing of a traditional connecting rod, one of the most problematic bearings in a traditional engine, is eliminated. An alternate design, the Rand cam engine, replaces the plate with one or more sinusoidal cam surfaces. Vanes mounted parallel to a shaft mounted inside a cylindrical 'barrel' that are free to sliding up and down ride the sinuous cam, the segments formed by rotor, stator walls and vanes constituting combustion chambers.

Crookes radiometer The Crookes radiometer (also known as a light mill) consists of an airtight glass bulb containing a partial vacuum, with a set of vanes which are mounted on a spindle inside. The vanes rotate when exposed to light, with faster rotation for more intense light, providing a quantitative measurement of electromagnetic radiation intensity. The reason for the rotation was a cause of much scientific debate in the ten years following the invention of the device, but in 1879 the currently accepted explanation for the rotation was published. Today the device is mainly used in physics education as a demonstration of a heat engine run by light energy.
|
|
Over the years, there have been many attempts to explain how a Crookes radiometer works: #Crookes incorrectly suggested that the force was due to the pressure of light.. This theory was originally supported by James Clerk Maxwell, who had predicted this force. This explanation is still often seen in leaflets packaged with the device. The first experiment to test this theory was done by Arthur Schuster in 1876, who observed that there was a force on the glass bulb of the Crookes radiometer that was in the opposite direction to the rotation of the vanes. This showed that the force turning the vanes was generated inside the radiometer.

Large sections of the diffusers had broken away, and extensive fatigue cracking was found in the outer tapering shell and central axial cone. Large pieces of the diffuser casing had entered the gas circulator blades and caused heavy impact damage, and large amounts of debris had been transported down the gas duct. The Inlet Guide Vanes (IGVs), which were provided to enable the performance of individual gas circulators to be "trimmed," were found to be extensively damaged, and the rotor blades and outlet guide vanes also had extensive impact and fatigue damage. Large numbers of the nuts and bolts involved had been shaken loose.

Textron Aviation declared that they were confident that these problems will be solved when it powers the Citation Hemisphere. Until 2015, issues were mostly oil-fuel heat exchanger problems, carcass distortion and clearance control challenges of the high-pressure section. Optimizing the settings, the control laws and positioning of the variable stator vanes will recover a part of the losses, but not all. Flowpath will not be too modified and no stages or vanes will be added, the fixes selection will establish the length of the delay and the schedule will be revised before 2017 ends to recover all the surge margin and to operate as planned across the flight envelope.

Centrifugal systems are used in a wide range of manufacturing applications in industries including aerospace, automotive, medical, defence and food production. These systems use a perforated drum with specially designed vanes which rotate at very high speeds. Oil mist is drawn into the unit and impacts on the vanes at high velocity and specially designed synthetic pads assist the collection process and filter out stray solid particles. The centrifugal force then pushes the oil to the unit’s outer case where it drains back to the machine for re-use or collection and clean air is returned to the workshop through the top of the unit.

Particularly large cold traps are necessary when removing large amounts of liquid as in freeze drying. Cold traps also refer to the application of cooled surfaces or baffles to prevent oil vapours from flowing from a pump and into a chamber. In such a case, a baffle or a section of pipe containing a number of cooled vanes, will be attached to the inlet of an existing pumping system. By cooling the baffle, either with a cryogen such as liquid nitrogen, or by use of an electrically driven Peltier element, oil vapour molecules that strike the baffle vanes will condense and thus be removed from the pumped cavity.

The first successful guided flights were made in October 1939, with three of the first four flights using a Kreiselgeräte complete guidance and control system called SG-52. The SG-52 used a 3-gyro stabilized platform for attitude control and a tilt program, whose signals were mixed with rate gyros by a torquer device, and fed to a control system connected to the jet vanes by aluminum rods. The Siemens Vertikant control system first flew on 24 April 1940. The Siemens system used three gyros, stabilized by 3 rate gyros, and hydraulic servomotors to move the jet vanes to correct pitch and yaw, and control roll.

Early weather vanes had very ornamental pointers, but modern weather vanes are usually simple arrows that dispense with the directionals because the instrument is connected to a remote reading station. An early example of this was installed in the Royal Navy's Admiralty building in London – the vane on the roof was mechanically linked to a large dial in the boardroom so senior officers were always aware of the wind direction when they met. Modern aerovanes combine the directional vane with an anemometer (a device for measuring wind speed). Co- locating both instruments allows them to use the same axis (a vertical rod) and provides a co-ordinated readout .

Since all pumps require well-developed inlet flow to meet their potential, a pump may not perform or be as reliable as expected due to a faulty suction piping layout such as a close-coupled elbow on the inlet flange. When poorly developed flow enters the pump impeller, it strikes the vanes and is unable to follow the impeller passage. The liquid then separates from the vanes causing mechanical problems due to cavitation, vibration and performance problems due to turbulence and poor filling of the impeller. This results in premature seal, bearing and impeller failure, high maintenance costs, high power consumption, and less-than-specified head and/or flow.

Commonly, the cock feather is of a different color. However, if archers are using fletching made of feather or similar material, they may use same color vanes, as different dyes can give varying stiffness to vanes, resulting in less precision. When an arrow is four-fletched, two opposing fletches are often cock feathers, and occasionally the fletches are not evenly spaced. The fletching may be either parabolic cut (short feathers in a smooth parabolic curve) or shield cut (generally shaped like half of a narrow shield), and is often attached at an angle, known as helical fletching, to introduce a stabilizing spin to the arrow while in flight.

Vane motor A vane motor consists of a housing with an eccentric bore, in which runs a rotor with vanes in it that slide in and out. The force differential created by the unbalanced force of the pressurized fluid on the vanes causes the rotor to spin in one direction. A critical element in vane motor design is how the vane tips are machined at the contact point between vane tip and motor housing. Several types of "lip" designs are used, and the main objective is to provide a tight seal between the inside of the motor housing and the vane, and at the same time to minimize wear and metal-to-metal contact.

By adding a set of eccentrics and guide slots to the axle of the supercharger, the Powerplus actively controls the position of these vanes, such that they maintain a constant small clearance from the walls of the housing. This is enough spacing to avoid friction, but close enough to keep pumping efficient.

The air pressure inside the bulb needs to strike a balance between too low and too high. A strong vacuum inside the bulb does not permit motion, because there are not enough air molecules to cause the air currents that propel the vanes and transfer heat to the outside before both sides of each vane reach thermal equilibrium by heat conduction through the vane material. High inside pressure inhibits motion because the temperature differences are not enough to push the vanes through the higher concentration of air: there is too much air resistance for "eddy currents" to occur, and any slight air movement caused by the temperature difference is damped by the higher pressure before the currents can "wrap around" to the other side.

' windmill in Utrecht, Netherlands. James Corwith Windmill, Watermill, New York A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines and other applications. "a mill or machine operated by the wind usually acting on oblique vanes or sails that radiate from a horizontal shaft, especially: (a) wind-driven water pump or electric generator, (b) the wind-driven wheel of a windmill". Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Greater Iran during the 9th century, the vertical windmill in northwestern Europe in the 12th century.

The engines are designed to operate at a lower compression ratio, thus lowering the combustion pressure, allowing the use of an aluminium cylinder block that reduces weight."Mitsubishi Reveals New Concept-cX", Mitsubishi Motors Australia press release The 4N13 engine uses a Variable Geometry (VG) turbocharger with a variable vane turbine, which provides optimal boost pressure control for different driving conditions. The 4N14 engine also uses a VG turbocharger plus a Variable Diffuser (VD) that uses both variable geometry vanes in the turbine housing and a compressor with variable vanes in the diffuser passage, further improving combustion efficiency. Within the engine, Mitsubishi used an offset angle crankshaft that reduces friction, therefore noise and vibration, allowing the engine to run smoothly and quietly at all engine speeds.

Denyer, aged 20–21 and identifying as male at the time of her crimes, started to stalk and attack a number of women in and around the Melbourne suburb of Frankston during a five-month period in 1993. The first known incident attributed to Denyer occurred in February 1993, when Donna Vanes' Claude Street unit in Seaford was broken into. After a series of disturbing prank-calls, Vanes was fearful of being alone. Arriving home with her boyfriend at around 1:00am, having been out for about an hour, they found that her cats' throats had been slashed, as had the walls, furniture, and some of her baby's clothes. Female pornographic imagery was also found, and the message "Donna you’re dead" written in blood on the wall.

In the Rand engine, the camshaft moves the vanes so that they have a varying length exposed and so enclose a combustion chamber of varying volume as the engine rotates. The work done in rotating the engine to cause this expansion is the thermodynamic work done by the engine and what causes the engine to rotate.

The secondary mirror in the Lurie–Houghton is identical to the secondary mirror in a Newtonian telescope. An advantage of the Lurie–Houghton over the Newtonian is that the secondary mirror can be mounted to one of the corrector lenses, thus eliminating the spider mount. This eliminates star image diffraction spikes, caused by the vanes of the spider mount.

If light pressure were the cause of the rotation, then the better the vacuum in the bulb, the less air resistance to movement, and the faster the vanes should spin. In 1901, with a better vacuum pump, Pyotr Lebedev showed that in fact, the radiometer only works when there is low-pressure gas in the bulb, and the vanes stay motionless in a hard vacuum. Finally, if light pressure were the motive force, the radiometer would spin in the opposite direction, as the photons on the shiny side being reflected would deposit more momentum than on the black side where the photons are absorbed. This results from conservation of momentum - the momentum of the reflected photon exiting on the light side must be matched by a reaction on the vane that reflected it.

Described by journalist John Langdon-Davies in 1940: > As it fell from an aircraft, a small turbine on the nose turned to release a > spring loaded casing which, on opening, scattered 100 or more incendiary > bombs; the main HE charge in the tail of the weapon continued to fall as a > conventional bomb. Other descriptions make no mention of a main charge and instead describe a large cylinder with vanes at the back that open out when the weapon is dropped. The vanes cause the bomb to spin and this has the effect of opening the sides and scattering the submunitions by centrifugal force. In 1939, the Soviet Foreign Minister, Vyacheslav Molotov, claimed the Soviet Union was not dropping bombs on Finland, but merely airlifting food to starving Finns.

The simplest vane pump has a circular rotor rotating inside a larger circular cavity. The centers of these two circles are offset, causing eccentricity. Vanes are allowed to slide into and out of the rotor and seal on all edges, creating vane chambers that do the pumping work. On the intake side of the pump, the vane chambers are increasing in volume.

The air motor is made up of a center drum about the size of a soup can with four or more slots cut into it to allow for the vanes to be placed radially on the drum to form chambers around the drum. The drum is offset inside a round casing so that the inlet air for starting is admitted at the area where the drum and vanes form a small chamber compared to the others. The compressed air can only expand by rotating the drum, which allows the small chamber to become larger and puts another one of the cambers in the air inlet. The air motor spins much too fast to be used directly on the flywheel of the engine; instead a large gearing reduction, such as a planetary gear, is used to lower the output speed.

A string of such towers stood, each about 10 to 15 km from its two neighbours, running from Paris to Mainz (or Mayence, as the region's Napoleonic rulers called it). It was a semaphore station, one in a chain designed to transmit information quickly over great distances, encoding messages in the positions of the aforesaid vanes. Each of the possible positions of the vanes could stand for a letter, a figure, a whole word, or even a whole sentence. As the French withdrew in 1814, they destroyed each semaphore station as they went.Kirrweiler’s history In 1816, Kirrweiler passed as part of the Amt of Grumbach and under the terms of the Congress of Vienna to the Principality of Lichtenberg, a newly created exclave of the Duchy of Saxe-Coburg-Saalfeld, which as of 1826 became the Duchy of Saxe-Coburg and Gotha.

However, SAAB decided to use engines from de Havilland and Lycoming instead. In the end the B42 came to power the Infanterikanonvagn 103 assault gun. A follow-up called B44 powered the Pansarbandvagn 301 armoured personnel carrier. Volvo Aero delivers engine components, mainly complex engine structures like turbine exhaust casings, turbine mid frames, LPT cases, compressor housings, LPT shafts, vanes, and large rotating parts.

However, near-infrared and visible light more easily penetrate the glass. If the glass is cooled quickly in the absence of a strong light source by putting ice on the glass or placing it in the freezer with the door almost closed, it turns backwards (i.e. the silver sides trail). This demonstrates black-body radiation from the black sides of the vanes rather than black-body absorption.

The Danish inventor Jacob Ellehammer built the Ellehammer helicopter in 1912. It consisted of a frame equipped with two counter-rotating discs, each of which was fitted with six vanes around its circumference. After indoor tests, the aircraft was demonstrated outdoors and made several free take-offs. Experiments with the helicopter continued until September 1916, when it tipped over during take-off, destroying its rotors.

The failure the project launch came as a shock to von Braun, who set to trying to find the causes. He suspected both the guidance control system and the jet vanes. Additionally, he developed a theory that an electrostatic charge caused the parachute to deploy early in the first two launches. Tests conducted at Kummersdorf on an electrically insulated rocket seemed to discount this explanation.

An example of this is hail, when precipitation freezes. If the hail is severe enough, engine inlet guide vanes or compressor blades can bend or break under impact. Volcanic ash ejected into the atmosphere due to a volcanic eruption is another example of reduced engine performance due to weather. Particles of volcanic ash are abrasive at high speed, leading to abrasion on compressor fan blades.

Hanging under the bell there are four pairs of oral tentacles, about two thirds as long as the diameter of the bell. The upper halves of these are somewhat flattened and the lower halves divide into three vanes which have multiple, inrolled edges. Among these are suctorial mouthlets leading to the interior of the bell and various thick dangling filaments. There is no central mouth.

The font and cover The single stemmed Decorated style octagonal font has each wave of a frieze filled with an ogee trefoil and with battlements above. Suspended by a rope from the roof above is a tall and highly ornate font cover in Perpendicular Gothic style with carved figures, some original, in niches between diagonal pierced vanes with rich crocheting topped by a spire and winged angel.

The third lamella supports the third vane, which is located more distally and lies perpendicular to the other two vanes or lamellae. All three lamella have striations when viewed in a longitudinal section and these striations are perpendicular to the ‘9+2’ axoneme. Carpediemonas contains a single ovate nucleus, located anteriorly in the cell. The nucleolus can also be found subcentrally within the nucleus.

Usually, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, and internal combustion engines. Mechanically, a fan can be any revolving vane, or vanes used for producing currents of air.

Arum initially stated that if Margarito was not licensed to fight, then Vanes Martirosyan would take his place on the card. However, Arum later stated that the fight would be moved to a venue in a state that Margarito holds a license. On November 18, 2011, the NYSAC did not make a final vote as expected. Instead, they ordered Margarito to be examined by their own doctor.

Walvisteuthis, the stubby hook squids, is a genus of squid in the family Onychoteuthidae. The genus contains four species. They are characterised by possessing oval fins which are not drawn-out posteriorly, the gladius has elongated-rhomboid vanes and a short, blunt rostrum which is perpendicular to tip of gladius, the gladius is visible beneath skin at the dorsal midline and they only have primary occipital folds.

A type of pneumatic motor, known as a rotary vane motor, uses air to produce rotational motion to a shaft. The rotating element is a slotted rotor which is mounted on a drive shaft. Each slot of the rotor is fitted with a freely sliding rectangular vane. The vanes are extended to the housing walls using springs, cam action, or air pressure, depending on the motor design.

Palmer's Drainage Windmill is of an interesting design being one of only two ‘Hollow Post’ drainage mills left on the broads, the other being Clayrack Drainage Mill. The mill has a miniature cap and sails based on its more traditional big brother tower drainage mills which can be seen on other parts of the Norfolk Broads. It is winded by a pair of tail vanes.

In the reaction turbine, the rotor blades themselves are arranged to form convergent nozzles. This type of turbine makes use of the reaction force produced as the steam accelerates through the nozzles formed by the rotor. Steam is directed onto the rotor by the fixed vanes of the stator. It leaves the stator as a jet that fills the entire circumference of the rotor.
|
|
Hydristor There are several problems with the historical design. The vane tips radially contact the cam ring elliptic surface and cause a significant friction as the rotor and vanes turn. This friction is both pressure dependent and speed squared dependent due to RPM-squared centripetal forces. The speed is limited to about 6-7,000 RPM and the pressure is limited to about 2,500 PSI.

Eventually, Joseph Henning's financial struggles caught up to him, and he handed over the management of the theatre to John T. Jackson in 1894, who married Joseph's daughter, Huldah Henning. Together they managed the theatre with Henning ultimately handing over ownership of the theatre to John and Huldah in 1904. They owned and operated the theatre until its sale to Dennis Vanes in 1920.Gillespie, pg.

This was done by replacing the multiple individual chambers with a single annular casing with individual flame tubes or cans known as cannular. The pressure ratio was increased and variable inlet guide vanes fitted to prevent low-RPM problems (rotating stall/blade flutter) with the higher design pressure ratio. A 2-stage turbine was required. A low boost (10% at take-off) afterburner was fitted.

The watermill section had 3 pairs of stones, and the windmill had a further 2 pairs. Both mills were built in 1737, being constructed of brick, the watermill having two storeys under a Norfolk pan tiled roof, with a third storey being added later. The windmill was originally built with five floors, but a sixth was subsequently added. In 1825 the sails had copper vanes.

Bargeboards (red) and turning vanes (orange) shown on a Formula 1 car, circa 2007 Bargeboards (red) and turning vanes (orange) shown on a Formula 1 car, circa 2007 Bargeboards are pieces of bodywork on open-wheel racing cars, serving a purely aerodynamic (as opposed to structural) function. They are curved vertical planes situated longitudinally, between the front wheels and the sidepods, held away from the chassis at the front on struts or other connectors, and connecting to the sidepods or extensions of the floor at the rear. In general, they are significantly taller at the front than at the rear making them trapezoidal in profile, and they curve outward in plan view, being closer to the centerline of the car at the front, and curving out towards the rear. Bargeboards were introduced by McLaren at the 1993 South African Grand Prix, before being adopted by Benetton and other teams.

Cooling air for the turbine vanes undergoes a similar process. Cooling the leading edge of the blade can be difficult, because the pressure of the cooling air just inside the cooling hole may not be much different from that of the oncoming gas stream. One solution is to incorporate a cover plate on the disc. This acts as a centrifugal compressor to pressurize the cooling air before it enters the blade.

Late in the XJ40 run 3.2S and 4.0S, in 1993-1994, Jaguar introduced the Sport model. It was available only with the six-cylinder engine, and featured rosewood interior trim (as opposed to the walnut trim of other models.) Both the door mirrors and radiator grill vanes were colour-keyed to the body, which was decorated with twin coachlines. Wider-profile tires were fitted, mounted on five-spoke alloy wheels.

This is the only album featuring their original "Old English Gothic" logo, this logo were used by the band until 1985 when it was changed. The old logo is still popular today as it appears on some merchandise as T-shirts and other items. The artwork is designed by Terry Greer and the snake symbolizes the S in Syron and the two arrows together symbolizes the V in Vanes.

The remaster is digitized from vinyl and any cracks and pops is digitally removed. The album was digitally remastered and reissued 2012. The remaster have the same cover as the original vinyl but includes many unpublished pictures of the band during that era. It also includes two bonus tracks "Violation" from a compilation album Syron Vanes appeared on 1982, and also a demo track from 1983 called "Steal And Run".

It was announced that Lara would be defending his titles in a rematch from 2012 with Vanes Martirosyan, which ended in a draw. The fight was to take place as part of a triple header also including the Charlo twins and Austin Trout. The fight took place on 21 May 2016, in Las Vegas. On fight night, Lara unofficially weighed 160.5 pounds while Martirosyan came in at 170 pounds.

Unlike an ideal gas, though, in which tiny particles move constantly, stopping the shaking would simply cause the beads to drop. In the experiment, this necessary out-of-equilibrium environment was thus maintained. Work was not immediately being done, though; the ratchet effect only commenced beyond a critical shaking strength. For very strong shaking, the vanes of the paddle wheel interacted with the gas, forming a convection roll, sustaining their rotation.

They almost doubled the size of the elevator and rudder and moved them about twice the distance from the wings. They added two fixed vertical vanes (called "blinkers") between the elevators and gave the wings a very slight dihedral. They disconnected the rudder from the wing-warping control, and as in all future aircraft, placed it on a separate control handle. When flights resumed the results were immediate.

A close clearance between vanes and pump volute or back plate prevent most of fluid from flowing back. Wear on the bowl and edge of vane can be compensated by adjusting the clearance to maintain efficiency over time. Because the internal parts are visible, open impellers are easier to inspect for damage and maintain than closed impellers. They can also be more easily modified to change flow properties.

The INF treaty only covered the destruction of the launchers and rocket motors. The W-85 warheads used in the Pershing II missiles were removed, modified, and reused in the B61 nuclear bomb. The Orbital Sciences Storm I target missile used air vanes from the Pershing 1a. The Pershing II guidance section was re-used in the Coleman Aerospace Hera and the Orbital Sciences Corporation Storm II target missiles.

This serves to ensure the instrument is level while simultaneously measuring the altitude of the sun. The altitude is the difference in the angular positions of the shadow and sighting vanes. With some versions of this instrument, the sun's declination for each day of the year was marked on the arc. This permitted the navigator to set the shadow vane to the date and the instrument would read the altitude directly.

Shelburne Museum's collection of 130 weathervanes includes finely crafted vanes as well as commercially produced examples. The tradition of surmounting buildings with weathervanes extends to antiquity when, as early as 100 BCE, a vane crowned the Athenian Tower of the Winds. Throughout the Medieval period, European churches displayed roosters, symbols of vigilance, from their bell towers. By the seventeenth century, English settlers had brought the tradition to America.

A special underwater version of the standard UFO design is seen in "Sub-Smash". In flight they are surrounded by horizontally spinning vanes, and emit a distinctive pulsing electronic whine that sounds like a Shoooe-Wheeeh! (produced by series composer Barry Gray on an ondes Martenot).Distinctive UFO sound can be heard here: The craft is armed with a laser-type weapon, and conventional explosive warheads can destroy it.

72 derived from the Goths.William Shepard Walsh, A Handy Book of Curious Information A few churches used weather vanes in the shape of the emblems of their patron saints. The City of London has two surviving examples. The weather vane of St Peter upon Cornhill is not in the shape of a rooster, but a key; while St Lawrence Jewry's weather vane is in the form of a gridiron.

The roofline has the same treatment as the flat portions of the roof. The southeast and southwest facades of the corner towers have a small arched window with fanlight flanked by two small smooth wooden Doric pilasters. Similar openings in the other sides have been shingled over in slate. Atop the towers are bell-cast roofs shingled in slate and topped by finials as well with weather vanes.

Boarding facilities for approximately 100 pupils are also situated on the Vanes campus. There has been some conjecture about which is the oldest school in South Africa. For example, SACS in Cape Town claims on its website and in published material to be the oldest school in South Africa. However, it was only established in 1829 at which point Muir already had 70 pupils and is some 5 years older.

According to Reti, the first machine that could be characterized as a centrifugal pump was a mud lifting machine which appeared as early as 1475 in a treatise by the Italian Renaissance engineer Francesco di Giorgio Martini. True centrifugal pumps were not developed until the late 17th century, when Denis Papin built one using straight vanes. The curved vane was introduced by British inventor John Appold in 1851.

Vaneaxial fans – These axial flow fans have a higher pressure capability due to the presence of static vanes. Variable pitch axial fans – The blades on these axial fans are manually adjustable to permit the blade angle to be changed. This allows operation over a much wider range of volume/pressure relationships. The blades are adjusted periodically to optimize efficiency by matching the blade pitch to the varying conditions for the application.

The fourth stage has round- headed belfry openings and on the north and south sides are clock faces dated 1977. The clock mechanism was made by JB Joyce & Co of Whitchurch. The top of the tower is surmounted by a balustrade with large urn corner finials with weather vanes, and smaller intermediate finials. A stone gutter runs around the body of the church at the base of the walls.

The pump itself is a multi-stage unit with the number of stages being determined by the operating requirements. Each stage includes an impeller and diffuser. Each impeller is coupled to the rotating shaft and accelerates fluid from near the shaft radially outward. The fluid then enters a non-rotating diffuser, which is not coupled to the shaft and contains vanes that direct fluid back toward the shaft.

These barbules have minute hooks called barbicels for cross- attachment. Down feathers are fluffy because they lack barbicels, so the barbules float free of each other, allowing the down to trap air and provide excellent thermal insulation. At the base of the feather, the rachis expands to form the hollow tubular calamus (or quill) which inserts into a follicle in the skin. The basal part of the calamus is without vanes.
|
|
The vanes of the feathers are so close together that light is diffracted, causing the user to receive two slightly offset images. For instance, if viewing a pencil, one would see two offset images of the pencil. Where the images overlap, a darker image is obtained, giving the illusion that one is seeing the graphite embedded within the body of the pencil. Newer versions utilize manufactured diffraction lenses instead of feathers.

In the terminology of the time, the edge of an alidade at which one reads a scale or draws a line is called a fiducial edge. Alidade B in the diagram shows a straight, flat bar with a vane at either end. No pointers are used. The vanes are not centred on the bar but offset so that the sight line coincides with the edge of the bar.
|
|
The vanes have a rectangular hole in each with a fine wire held vertically in the opening. To use the alidade, the user sights an object and lines it up with the wires in each vane. This type of alidade could be found on a plane table, graphometer or similar instrument. Alidades A and C are similar to B but have a slit or circular hole without a wire.

The square towers at each of its four corners were crowned with onion domes. The gilded vanes on top of these domes could be seen from all parts of the city, as they stood clear above the surrounding structures of the bridge. The house had two sundials on top on the south side. On one of them was painted the adage: Time and tide stay for no man.

Sir Edward Bullock purchased the Hall and the manor of Faulkbourne in 1637 and made substantial additions to the building. Further extensions were made in the 19th century. The Hall is considered a fine specimen of early Tudor red-brick design. Its exterior holds a number of metalled vanes in the form of flags bearing the initials of the Bullock family, which owned the Hall from 1637 to 1897.

This allowed the compressor to work properly with adequate surge margin and increased airflow into the compressor. Some of the increased flow left the compressor after the 4th stage as bypass to the afterburner and some left the last compressor stage through the previously-choked area. The increased airflow gave more thrust. The inlet guide vanes were modified with trailing edge flaps to reduce blade flutter and prevent blade fatigue failures.
|
|
They can also be driven separately via gears off a driveshaft. The vanes are enclosed in a static chamber with small clearances to the chamber's walls (which will also be vaned), as in an automatic transmission. When retardation is required, fluid (oil or water) is pumped into the chamber, and the viscous drag induced will slow the vehicle. The working fluid will heat, and is usually circulated through a cooling system.
|
|
This induces eddy currents in the rotor, which produces an opposing magnetic field to the stator. The opposing magnetic fields slows the rotor, and hence the axle, transmission or driveshaft to which it is attached. The rotor incorporates internal vanes (like a ventilated brake disk) to provide its own air cooling, so no load is placed on the vehicle's engine cooling system. The operation of the system is extremely quiet.

Nevertheless, in 1963, von Braun, reflecting on the history of rocketry, said of Goddard: "His rockets ... may have been rather crude by present-day standards, but they blazed the trail and incorporated many features used in our most modern rockets and space vehicles". He once recalled that "Goddard's experiments in liquid fuel saved us years of work, and enabled us to perfect the V-2 years before it would have been possible." After World War II von Braun reviewed Goddard's patents and believed they contained enough technical information to build a large missile. Three features developed by Goddard appeared in the V-2: (1) turbopumps were used to inject fuel into the combustion chamber; (2) gyroscopically controlled vanes in the nozzle stabilized the rocket until external vanes in the air could do so; and (3) excess alcohol was fed in around the combustion chamber walls, so that a blanket of evaporating gas protected the engine walls from the combustion heat.

A short-burn-time booster section exhausts through two large nozzles located midway between the rear edges of the missile's large fins, after which a longer-burn-time sustainer ignites, and exhausts through a nozzle located at the center of the back of the missile body. As with the AS-20, the AS-30 uses a simple MCLOS guidance with the pilot aligning the flares located near the missile's rear with the target and controlling the missile in flight after launch with a small joystick, sending steering commands to the missile via a radio link. The steering commands steer the missile back to the line-of-sight by thrust vectoring, by the movement of one of four metal vanes around the sustainer nozzle. The missile's internal gyro gives the missile command unit the correct position of the missile in flight, so each of the four thrust vanes can actuate at the correct time to steer the missile back to the correct flight path.

A fluid coupling works well when both the impeller and turbine are rotating at similar speeds, but it is very inefficient at initial acceleration, where rotational speeds are very different. This torque multiplication is accomplished with a third member in the coupling assembly known as the stator, which acts to modify the fluid flow depending on the relative rotational speeds of the impeller and turbine. The stator itself does not rotate, but its vanes are so shaped that when the impeller (which is driven by the engine) is rotating at a high speed and the turbine (which receives the transmitted power) is spinning at a low speed, the fluid flow hits the vanes of the turbine in a way that multiplies the torque being applied. This causes the turbine (and the vehicle) to accelerate more quickly when the engine speed increases (ideally), and as the relative rotational speeds equalize, the torque multiplication diminishes.

The wind vanes are attached to one of the gabled ends of the cap. Entrances are located at the northern and southern sides of the structures, and there are small windows on the second level. The mill was built in 1797 by Benjamin Godfrey, and was used to grind corn. It was originally located on Stage Harbor Road, and was moved to its present location in 1955, the year it was given to the town.

The Old Mill is 50 feet high, with four vanes 30 feet in length. The interior mechanism has a driving wheel at the top, connected to the blades. It has a fixed body containing machinery and a cap that turns to face the sails into the wind. Projecting from the driving wheel are wooden cogs that intersect with another set of wooden teeth in a vertical shaft, which in turn revolves the upper grindstone.

While being a fully aerobatic aircraft, it possesses favourable handling qualities, including relatively tame stall characteristics. Controllability during stalls is augmented by vanes located on the wing tip tanks which accelerate airflow over the tips and ailerons. The SF.260 is a relatively fast aircraft, complete with responsive controls; as a product of the latter, pilots need to maintain awareness of speed dips, although ample aerodynamic warning is typically present.Moll October 1984, pp. 70–72.

Diffraction spikes from various stars seen on an image taken by the Hubble Space Telescope Diffraction spikes are lines radiating from bright light sources, causing what is known as the starburst effect or sunstars in photographs and in vision. They are artifacts caused by light diffracting around the support vanes of the secondary mirror in reflecting telescopes, or edges of non-circular camera apertures, and around eyelashes and eyelids in the eye.

Two dipole UHF antennas and a long VLF antenna protruded from the bottom of the sphere. The transmitters operated on a frequency of 378 megahertz. Thermal control was planned to be achieved by fifty small "propeller blade" devices on the surface of the sphere. The blades themselves were made of reflective material and consist of four vanes which were flush against the surface, covering a black heat-absorbing pattern painted on the sphere.

The construction of closed impellers includes additional back and front walls on both sides of vanes that enhances its strength. This also reduces the thrust load on the shaft, increasing bearing life and reliability and reducing shafting cost. However, this more complicated design, including the use of additional wear rings, makes closed impellers more difficult to manufacture and more expensive than open impellers. A closed impeller's efficiency decreases as wear ring clearance increases with use.

The beaded crinoid has a cup shaped body, usually hidden from sight, from which about twenty arms project. Only a few of these are usually visible at one time and each can be curled up in a coil. Short pinnules extend from either side of the arms like vanes on a feather. Both the arms and the pinnules are formed from a large number of jointed plates which gives them great overall flexibility.

The innovation of the Powerplus was to take the sliding-vane design and to address its main drawbacks. Although the simple sliding-vane design is straightforward to manufacture, having simply shaped component parts, the spring-loaded vanes rub on the housing and this friction requires lubrication. In the 1920s, it was common for supercharged cars to have large consumable oil tanks mounted alongside the supercharger. Their HC exhaust emissions are not recorded.

Louisine Havemeyer and her Daughter Electra, 1895 pastel on paper by Mary Cassatt. Collection of Shelburne Museum The closing of one of the Webb's other homes, this one near the polo grounds at Old Westbury, unintentionally birthed a museum. The question of what would become of her cigar store Indians, hunting decoys, and weather vanes had to be settled. In 1947 Electra Havemeyer Webb gathered with her friends to create Shelburne Museum.

At the 1954 Farnborough Airshow, Fairey Australia displayed a massive missile resembling the RTV-1. The base was formed by a booster unit about 6 ft high and 20 inches in diameter, stabilised by four large and four small fins and housing seven five-inch motors. The main body was about 17 ft in length with a diameter of 10 in. The body was fitted with four wings and four small control vanes.

It used a three-gyroscope system to deflect tungsten alloy jet vanes. The design was finished and secretly patented in the spring of 1936 and further modifications that made the rocket stable at supersonic velocities were finalized in the autumn. The shape of the rocket was based on the 8-millimeter infantry bullet, in anticipation of supersonic flight. The rocket was 22 feet in length, 2.3 feet in diameter, and weighed 1650 pounds when fueled.

The combined use of adjustable runner blades with moving guide vanes allows Deriaz pump-turbine to reach high performance under a large range of working conditions. This makes the Deriaz pump-turbine an extremely suitable turbomachine solution for high variable load. Recent investigation supported by experimental data and computational fluid dynamics (CFD) simulations, shows clearly how a downsized prototype preserves versatility over a wide range of partial load for pumping and generating modes.

The Bell and Carillon Museum (French: Musée de la Cloche et du Carillon; Dutch: Klokken- en Beiaardmuseum) was a museum from 1992 to 2013 in Tellin in the Belgian Ardennes. The museum was established in a bell foundry that was in service between 1830 and 1970. Beside bells and carillons it showed other objects, like weather-vanes that had been on church towers. There was also a documentary film shown on the process of molding.

Note progression in turbine rotor inlet temperature and number of cooled rows (turbine vanes and blades). The W501A was immediately preceded by the W301, the first direct- drive design. The upgrade involved adding two stages to the compressor (one fore and one aft) and a new turbine design with a cooled first-stage vane. Ed.

Some types rely on pistons and cylinders; others on slotted rotors with vanes (vane motors) and others use turbines. Many compressed air engines improve their performance by heating the incoming air or the engine itself. Pneumatic motors have found widespread success in the hand-held tool industry, but are also used stationary in a wide range of industrial applications. Continual attempts are being made to expand their use to the transportation industry.

Krupp's LG 40 was basically an enlarged and improved version of their unsuccessful competitor to Rheinmetall's 75 mm recoilless gun. It retained the earlier model's side- swinging breech and large pneumatic tires. It incorporated torque vanes in the jet nozzle to counteract the torque forces imparted by the round engaging the rifling and any clogged or eroded nozzles. It also used the improved priming mechanism developed after the problems with the smaller weapon became apparent.

Liquid sprayed from nozzles on a center post (manifold) is directed toward the chamber walls and through the swirling gas. As in the irrigated cyclone, liquid captures the pollutant, is forced to the walls, and washes out. The "cleaned" gas continues upward, exiting through the straightening vanes at the top of the chamber. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers.

The bolt's total weight includes the bolt's weight, nock, insert, vanes, and broadhead or field point. Almost all bolt manufacturers will list how many grains each shaft weighs or how many grains are in each inch of the shaft. A more massive bolt, e.g. at least 400 grains, will have better downrange energy and offer better penetration, but will travel more slowly and thus drop more due to gravity during its flight.

The vane was in the shape of a monk's silhouette. Whilst most of the weather vanes and summit symbols were destroyed or dismantled again in the succeeding decades, that on the Mönch was one of the few that remained in Saxon Switzerland. The original figure suffered damage, in 1928 and 1930, and was replaced in 1957 by a faithful replica. The original monk of 1887 may be seen in the museum in Bad Schandau.

The specific speed, along with some fundamental formulas can be used to reliably scale an existing design of known performance to a new size with corresponding performance. Off-design performance is normally displayed as a turbine map or characteristic. The number of blades in the rotor and the number of vanes in the stator are often two different prime numbers in order to reduce the harmonics and maximize the blade-passing frequency. Tim J Carter.

Afterburner fuel injectors are integrated into these vanes, which block line-of-sight of the turbines, contributing to aft- sector stealth. The axisymmetric nozzle consists of fifteen partially overlapping flaps that create a sawtooth pattern at the trailing edge. This creates shed vortices and reduces the infrared signature of the exhaust plume. The effectiveness is reportedly comparable to that of the F119's wedge nozzles, while being substantially more cost effective and lower maintenance.

The turbine was named after its inventor and designer, the American farmer Daniel Halladay. The runner consists of a chain of operable vanes controlled by rods, enabling them to be tilted as required automatically according to the wind. Double tail vane maintained the wheel at the right course. The turbine is now rotating at a height of 16 m above the ground, its diameter is 10 m and it weighs about 2 tons.

Improving the Corporal E involved drastic changes in the rocket motor, airframe, guide vanes and control system. The design was changed to a more easily produced, assembled, and accessible structure. The means of launching was changed from the rocket sitting upon its fins to being held by four arms holding it above the fins which would retract to release it. The first of the redesigned Corporal E missiles was available in May 1949.

Plus, there was criticism that the license issue was not to be resolved until 2 weeks before the fight. Arum initially stated that if Margarito was not licensed to fight, then Vanes Martirosyan would take his place on the card. However, Arum later stated that the fight would be moved to a venue in a state that Margarito holds a license. On November 18, 2011, the NYSAC did not make a final vote as expected.

Similarly, the pulp caps, which protect the dermal core, also fall off as the feather grows. The main feather tissues later unfurl, which causes the disposal of the sheath and the pulp caps as it assumes its functional shape. As the feather grows, its spathe, which is where the rachis and vanes attach, continues to form. When spathe is finished developing, the calamus begins to form within the base of the spathe.

Vertical division of the front facade emphasizes the extreme vanes, large windows on the first floor and two-tiered windows of the operating room. These windows are divided by four piers with high relief masks, which support the bank's logo sign. The facade is completed by a large overhanging cornice, above which there is a parapet with curbstones. Rustication of the first floor, cornice and arched entrance are elements borrowed from Classical architecture.

A complex air system is built into most turbine based jet engines, primarily to cool the turbine blades, vanes and discs. Air, bled from the compressor exit, passes around the combustor and is injected into the rim of the rotating turbine disc. The cooling air then passes through complex passages within the turbine blades. After removing heat from the blade material, the air (now fairly hot) is vented, via cooling holes, into the main gas stream.

Cup-type anemometer with vertical axis, a sensor on a remote meteorological station An occluded mesocyclone tornado (Oklahoma, May 1999) Wind direction is usually expressed in terms of the direction from which it originates. For example, a northerly wind blows from the north to the south. Weather vanes pivot to indicate the direction of the wind. At airports, windsocks indicate wind direction, and can also be used to estimate wind speed by the angle of hang.

A much smaller luminaire, with a head approximately 300mm in length, available in a black or white finish and designed for indoor use. All functions were motorised, including Pan and Tilt, making the AR5 a true moving light. Colour, Intensity and Diffusion were handled by miniaturised versions of the mechanisms used in the AR500, using just eight vanes per set, instead of sixteen. The light source was a 35W discharge lamp, powered from an internal supply.

The scale is marked to show the direction of rotation corresponding to the "incoming" machine running faster than the "running" system. When the frequencies match, the moving vanes will rotate to a position corresponding to the phase difference between the two sources. The incoming machine can then be adjusted in speed so that the two systems are in phase agreement. In the moving iron instrument, an iron vane is mounted on a shaft along with the pointer.

Fläkt Woods provided the ventilation solutions by supplying three immense fans for the tunnel. The axial flow fans measured 2.65 m in diameter, were powered by 900 kW motors and ran at pressures of 3,800 Pa. Fläkt Woods ran one of the fans continuously to self-destruct, to prove their capability of withstanding temperatures of up to 400 °C for one hour. The fans incorporated guide vanes for flow straightening to achieve maximum performance and ran at 995 RPM.

The date of erection is not known, but it would seem to have been in existence by March 1791, when there was an advert in the Kentish Gazette in relation to the patent vanes used in the mill. The mill was demolished circa 1828. An illustration of the mill in Rees's Cyclopædia shows that the windmill had forty vertical sail blades mounted on the vertical Windshaft-cum-Upright Shaft. It drove three pairs of overdrift millstones.

Evil Redux was a statement to get back to the classic Heavy Metal style Syron Vanes are known for. In 2011, Rimbert and Anders discussed how to make the best album in their careers to date and the conclusion was that they have to get back to their roots with classic Heavy Metal. A record with classic songs combined with a thunderous sound was the idea. 16 songs were written and 14 made it to the album.

64–9 (cf. Donald Routledge Hill, Mechanical Engineering) In the Ottoman Empire, a practical impulse steam turbine was invented in 1551 by Taqi al-Din Muhammad ibn Ma'ruf in Ottoman Egypt. He described a method for rotating a spit by means of a jet of steam playing on rotary vanes around the periphery of a wheel. Known as a steam jack, a similar device for rotating a spit was also later described by John Wilkins in 1648.

An opportunity arose in the Summer of 2013 when the vacant WBO light middleweight title would be decided by one match between Andrade and Armenian contender Vanes Martirosyan (33-0-1, 21 KOs). Andrade was scheduled to fight titlist Zaurbek Baysangurov on July 6 in Kiev, Ukraine. Baysangurov was stripped after suffering a back injury and being sidelined for an extended period of time. The fight took place on November 9, 2013, at the American Bank Center in Texas.

An audible waning horn warns of flap extension to more than 25 degrees if the landing gear is not down and locked. The stall warning system utilizes a stall warning vane on each side of the nose. The vanes provide regulated voltage input to the angle-of-attack transducers, modified by a stall warning bias box to compensate for flap position. The angle-of-attack transducer supplies a proportional voltage to the angle-of- attack of the aircraft.

The US A.E.F. in France reported in March 1918 : "... a new pattern minenwerfer which was brought out in 1916 and looks very much like the French 240... uses a heavy bomb fitted with four vanes like the French 240 mm bombs. This bomb weighs 100 kg (220 lb) and contains 42 kg (93 lb) of explosive... ranges obtained vary from 490 to 1310 yards"."Manual for trench artillery, United States Army (provisional).

Here it re-enters realspace, traveling at the same heading as it was before it entered the jumpspace, but at a velocity which is a large fraction of C (the speed of light).Cherryh, C.J. (1982) Merchanter's Luck p. 43 & 44. Back in normal space the ship dumps velocity by cycling its vanes to graze the interface, like casting an anchor hyperspace, before the STL thrusters take are used to slow the ship further at system-safe velocities.

The flight control was carried out with the help of four carbon jet vanes, located in the nozzles of the rocket motors. The autonomous guidance and control system used center of mass normal and lateral stabilization devices, a velocity control system and a computer-assisted automatic range control system. The R-12 was deployed at both soft launch pads and hard silos. Standard thermonuclear explosive charges 2.3 Mt. Explosive charges or chemical weapons could have been used as well.

Restoration The bones of the tail have not been preserved in any known specimen, but comparison with related species suggest it was short with a small, plowshare-shaped pygostyle bone, to which the tail feathers anchored. A mass of muscles, called the rectorial bulb, probably was present to control the fanning of the trail feathers. The tail feathers were long, with symmetrical vanes. There were at least 10 tail feathers (rectrices), more than in other primitive fan-tailed birds.

Bell constructed the X-14 as an open-cockpit, all-metal (duralumin) monoplane for the USAF. It was powered by two Armstrong Siddeley Viper turbojet engines equipped with thrust deflectors sited at the aircraft's centre of gravity. The engines are fixed in position; transition from vertical to horizontal flight is achieved with a system of movable vanes that control the direction of engine thrust. Top speed was 180 miles per hour with a service ceiling of 20,000 feet.

The Voluntary Anti-Doping Association (VADA) stated that Álvarez was not enrolled in their testing program. His promoter De La Hoya then announced that Álvarez would return to the ring on Mexican Independence Day weekend. According to Golovkin on 27 April, before he defeated Vanes Martirosyan, a fight with Álvarez in the fall was still a priority. During a conference call, he stated it was the "biggest fight in the world" and beneficial for all parties involved.

To estimate the energy production of a wind farm, developers must first measure the wind on site. Meteorological towers equipped with anemometers, wind vanes, and sometimes temperature, pressure, and relative humidity sensors are installed. Data from these towers must be recorded for at least one year to calculate an annually representative wind speed frequency distribution. Since onsite measurements are usually only available for a short period, data is also collected from nearby long-term reference stations (usually at airports).

Château de Montmort Aerial view The Château de Montmort is a stately home built on the site of a medieval castle in the commune of Montmort-Lucy in the Marne département of France.Ministry of Culture: Château de Montmort . Retrieved 5 January 2019. Describing the château, Victor Hugo wrote of a "delightful hustle and bustle of turrets of weather vanes, gables, skylights and fireplaces" (ravissant tohu-bohu de tourelles de girouettes, de pignons, de lucarnes et de cheminées).

After a crash in 1905, they rebuilt the Flyer III and made important design changes. They almost doubled the size of the elevator and rudder and moved them about twice the distance from the wings. They added two fixed vertical vanes (called "blinkers") between the elevators, and gave the wings a very slight dihedral. They disconnected the rudder from the wing-warping control, and as in all future aircraft, placed it on a separate control handle.

The Grim Wheels were designed to recover lost propeller thrust and reduce fuel consumption by 2.5 to 3%. After the trial of these wheels, when the ship was drydocked, the majority of the vanes on each wheel were discovered to have broken off. The wheels were removed and the project abandoned. Other machinery includes nine heat recovery boilers, coupled with two oil-fired boilers to produce steam for heating fuel, domestic water, swimming pools, laundry equipment, and galleys.

The GE Affinity has a nine-stage HP compressor, a single-stage HP turbine and a two- stage low-pressure turbine. Preceded by fixed inlet guide vanes with movable flaps, the twin blisk fans have wide-chord titanium blades. The exhaust mixer is similar to the GE Passport ceramic matrix composite design. The Mach 1.4-to-1.6 speed requires no variable-geometry inlet and the variable-area nozzle has a cone moving longitudinally, replacing a convergent-divergent nozzle.

A male-female guild has been established devoted to Our Lady of the Enclosed Garden, with the purpose of praying for the wellbeing of Church and diocese. At least once a year, on the Saturday before Mother's Day, there is a Mass followed by a procession from the parish church in Wehe-den Hoorn to the hermitage to have Eucharistic Adoration. The guild also issues Holy cards and pilgrimage vanes and assists the hermit in receiving groups of pilgrims.

Unlike some military engines, modern civil turbofans lack stationary inlet guide vanes in front of the fan rotor. The fan is scaled to achieve the desired net thrust. The core (or gas generator) of the engine must generate enough power to drive the fan at its design flow and pressure ratio. Improvements in turbine cooling/material technology allow a higher (HP) turbine rotor inlet temperature, which allows a smaller (and lighter) core and (potentially) improving the core thermal efficiency.

Prior to its cancellation, Sunjammer was slated for launch in January 2015 aboard a Falcon 9 rocket, a slight delay from an earlier projection of November 2014. It was to launch as a secondary payload along with the primary DSCOVR Earth observation and space weather satellite. Within two months of launch the spacecraft was to test various technologies, such as deployment, vector control via altitude vanes, and eventually reaching a location near the Earth- Sun L1 Lagrangian point.

In their stage shows, Townshend developed a guitar stunt in which he would swing his right arm against the guitar strings in a style reminiscent of the vanes of a windmill. He developed this style after watching Rolling Stones guitarist Keith Richards warm up before a show. Townshend's "windmill" technique The Who commenced their first US tour on 22 March 1967. Townshend took to trashing his hotel suites, though not to the extent of his bandmate Moon.

The LG 42 was basically an enlarged and improved version of the 7.5 cm LG 40. It incorporated torque vanes in the jet nozzle to counteract the torque forces imparted by the round engaging the rifling and any clogged or eroded nozzles. It also used the improved priming mechanism developed after the problems with the smaller weapon became apparent. Like all the German 10.5 cm recoilless rifles it shared shells with the 10.5 cm leFH 18 (light Field Howitzer).

Gas, often air, is drawn into the pump through an inlet port in the end of the casing. The gas is trapped in the compression chambers formed by the impeller vanes and the liquid ring. The reduction in volume caused by the impeller rotation compresses the gas, which reports to the discharge port in the end of the casing. Compressed gas on discharge of pump contains certain amount of working liquid which is usually removed in vapor–liquid separator.

In the 1970s, Whirlpool developed a dual-action washing machine agitator that utilized the bottom portion of the shaft for the usual oscillating motion but added an upper sleeve that was designed to work as an auger. The auger propelled water and clothing downwards toward the agitator's oscillating vanes so as to produce more uniform scrubbing. Whirlpool secured three Canadian patents for this work. In the first patent, the dual agitator was powered by a drive shaft.

In 1551 Taqī al-Dīn described a self-rotating spit that is important in the history of the steam turbine. In Al-Turuq al-samiyya fi al-alat al-ruhaniyya (The Sublime Methods of Spiritual Machines) al-Dīn describes this machine as well as some practical applications for it. The spit is rotated by directing steam into the vanes which then turns the wheel at the end of the axel. Al-Dīn also described four water-raising machines.

In order to train these weapons, the ship had to be aimed, like a gun, at its target. Compressed air from a 1000 psi (70 atm) reservoir projected the shells from the dynamite guns. Two air compressors were available to recharge the reservoir. The shells fired from the guns were steel or brass casings 7 feet (2 meters) long with the explosive contained in the conical forward part of the casing and spiral vanes on the after part to rotate the projectile.

Much to their amazement the unit more than met the design target, including that of high efficiency. A modified version of this research unit was subsequently incorporated into the CJ805-23 aft fan. With no experience of transonic fan design and little time available, Pratt & Whitney had to resort to using 2 fan stages to produce a similar pressure ratio for their JT-3D turbofan. Although not an overhung design, the -23 transonic fan did not require any inlet guide vanes.

The effect begins to be observed at partial vacuum pressures of several hundred pascals (or a few torr), reaches a peak at around 1 pascal (7.5 x 10−3 torr) and has disappeared by the time the vacuum reaches 10−4 pascal (7.5 x 10−7 torr) (see explanations note 1). At these very high vacuums the effect of photon radiation pressure on the vanes can be observed in very sensitive apparatus (see Nichols radiometer) but this is insufficient to cause rotation.

They also appear to have had internal organ-like structures unlike anything found in living ctenophores. One of the fossil species first reported in 1996 had a large mouth, apparently surrounded by a folded edge that may have been muscular. Evidence from China a year later suggests that such ctenophores were widespread in the Cambrian, but perhaps very different from modern species – for example one fossil's comb-rows were mounted on prominent vanes. The Ediacaran Eoandromeda could putatively represent a comb jelly.

Goddard determined early that fins alone were not sufficient to stabilize the rocket in flight and keep it on the desired trajectory in the face of winds aloft and other disturbing forces. He added movable vanes in the exhaust, controlled by a gyroscope, to control and steer his rocket. (The Germans used this technique in their V-2.) He also introduced the more efficient swiveling engine in several rockets, basically the method used to steer large liquid-propellant missiles and launchers today.

The mast tops and wind vanes were often painted or shaped (respectively) to identify the wherry's owner - a traditional design is a 'Jenny Morgan', after a folk song character. Sizes varied, but many of these vessels would carry around 25 tons of goods. Wherries were able to reach larger boats just off the coast at Great Yarmouth or Lowestoft and take their cargoes off to be transported inland through the broads and rivers. The last trading wherry, Ella, was built in 1912.

In the summer of 1937 the German Aggregate 3 series of rockets was nearing the testing stage. Several were tested on a special stand at Kummersdorf in an attempt to evaluate guidance systems. These consisted of vanes designed to deflect the rocket exhaust and control the missile's course. On September 1, Dornberger ordered that von Braun's team prepare for a series of test launches in the first part of November from the small island of Greifswalder Oie in an operation he designated "Lighthouse".

It may have been made in France, perhaps in the circle of Rustici, who entered Francis I's service in 1528. Vasari tells of the elaborate suppers given by Rustici and his comrades. Rustici's Mercury was commissioned by Cardinal Giuliano de' Medici in 1515 as a fountain figure for the courtyard of Palazzo Medici in Florence. The figure blew a jet of water that spun a whirligig with four vanes in the form of butterfly wings, according to Giorgio Vasari's description.

Two of the jet vanes rotated in the same direction for pitch and yaw control, and in the opposite direction for roll control. The guidance and control system was designed by Fritz Mueller, based on Johannes Maria Boykow's ideas, the technical director of Kreiselgeräte GmbH (Gyro Instruments, Limited). The A-3 engine was a scaled up version of the A-2, but with a mushroom-shaped injector at the top of the combustion chamber, based on a design by Walter Riedel.

9M317ME missiles can be fired at 2-second intervals, while its reaction (readiness) time is up to 10 s. The missile was designed to be single-staged, inertial guidance, radio control mid-course update and terminal semi-active radar homing. The tail surfaces have a span of 0.82 m when deployed after the missile leaves the launch container by a spring mechanism. Four gas-control vanes operating in the motor efflux turn the missile towards the required direction of flight.

The "ram air inlet" is a small scoop, generally located on the "wing to body fairing." Nearly all jetliners use a modulating door on the ram air inlet to control the amount of cooling airflow through the primary and secondary ram air heat exchangers. To increase ram air recovery, nearly all jetliners use modulating vanes on the ram air exhaust. A "ram air fan" within the ram system provides ram air flow across the heat exchangers when the aircraft is on the ground.

A pair of one row of rotating airfoils and the next row of stationary airfoils is called a stage. The rotating airfoils, also known as blades or rotors, accelerate the fluid in both the axial and circumferential directions. The stationary airfoils, also known as vanes or stators, convert the increased kinetic energy into static pressure through diffusion and redirect the flow direction of the fluid to prepare it for the rotor blades of the next stage.Perry, R.H. and Green, D.W. (Eds.) (2007).

The player must pilot a biplane through a series of barns in the shortest time possible while dodging windmills, weather vanes, and geese. Bumping into anything slows down the plane for a couple of seconds, increasing the overall time. There are four levels of play determined by the game select switch. Game 1 is Hedge Hopper (10 barns), game 2 is Crop Duster (15 barns), game 3 is Stunt Pilot (15 barns), and game 4 is Flying Ace (25 barns).

At first the windmill was manufactured by L. H. Wheeler and Sons. In February 1872 Wheeler died. In 1873 Wheeler's sons, along with S. T. Merrill and C. B. Salmon, organized the Eclipse Wind Mill Company and the company began to grow steadily. At first the wheel design used four vanes, but this was changed to a wheel with a dense pattern of fins, a signature of the Eclipse, and was manufactured in several diameters from 8 1/2 to 14 feet.

The young cast of TV show El club del clan, circa 1963. In 1960, RCA Victor general manager Ricardo Mejía discovered through a market research that there were almost no popular music stars among the youth. As a result, the company began the selection of new singers, initiating the phenomenon of the nueva ola in Argentina. Led by Mejía, RCA executives partnered with future journalist Leo Vanes and musicians Ray Nolan and Jimmy Lerman to create the TV show El club del clan.

Front automobile brake with rectangular open slots visible between the disc's friction surfaces The brake disc (or rotor) is the rotating part of a wheel's disc brake assembly, against which the brake pads are applied. The material is typically gray iron, a form of cast iron. The design of the discs varies somewhat. Some are simply solid, but others are hollowed out with fins or vanes joining together the disc's two contact surfaces (usually included as part of a casting process).

The RD-214 (GRAU Index 8D59) was a liquid rocket engine, burning AK-27I (a mixture of 73% nitric acid and 27% N2O4 \+ iodine passivant and TM-185 (a kerosene and gasoline mix) in the gas generator cycle. As was the case with many V-2 influenced engines, the single turbine was driven by steam generated by catalytic decomposition of H2O2. It also had four combustion chambers and vector control was achieved by refractory vanes protruding into the nozzle's exhaust.

This fixes the compass card, from which the magnetic azimuth or amplitude can be read. The sights may consist of two vanes, one with a narrow slit and the other with a wider slit bisected by a thread. The observer looks towards the sun, seen through a dark glass, lining up the thread and the narrow slit on the center of the sun. Another arrangement has a vertical bar on one vane and a slit bisected by a thread on the other.

The manor of Tixall was held for many years by the Littleton family until 1507 when the Littleton heiress married Sir John Aston. The medieval manor house was replaced by Sir Edward Aston, High Sheriff of Staffordshire, in about 1555 and the Gatehouse was added in about 1580. The Gatehouse is a three-storey rectangular structure, the balustraded facade of which is decorated with three orders of twinned columns. There are four octagonal corner turrets topped with cupolas and weather vanes.

Coal- laden air passes through double cone static classifiers, with adjustable classifier vanes, for segregation into pulverized fuel of the desired fineness, and coarse particles. The pulverised fuel continues its journey towards the coal burners for combustion. The coarse particles rejected in the classifier are returned to the mill for another cycle of grinding. In order to avoid excess sweeping of coal from the mill, only part of the primary air, directly proportional to the boiler load demand, is passed through the mill.

Fiske's designs ranged from the naturalistic foliate designs that were the stock-in-trade of mid-Victorian style to sculptures after the Antique or neoclassical works of Antonio Canova or Bertel Thorvaldsen, suitable for park-like landscapes of estates and landscape cemeteries of formal schemes. Fiske was also noted for his hammered copper weather vanes, produced in Williamsburgh, Brooklyn. Fiske's great rival in the decorative cast iron field was Jordan L. Mott's J. L. Mott Iron Works of New York City.Israel 2000.

The flight feathers are black with white on the basal portions of the vanes. The secondaries and inner primaries have pale yellow fringes on the outer web whereas the outer primaries have a white outer edge. After the autumn moult, the tips of the new feathers have a buff fringe that adds a brown cast to the coloured plumage. The ends of the feathers wear away over the winter so that by the spring breeding season the underlying brighter colours are displayed.

The different types and sizes of Garrett's turbochargers. Garrett offers gasoline-powered turbochargers called wastegate turbos. They are designed to be smaller than previous turbo generations, have higher fuel efficiency, more torque, and meet emissions standards. Garrett also offers Variable-geometry turbochargers called VNT. They have nine moveable vanes, an electrohydraulic actuator and a proportional solenoid for variable control throughout the engine’s power curve. This means the air passageway of the turbo varies to meet the engine’s needs at different RPMs.

On 20 June 2009 Édouard Brasey received the Prix Merlin in the novels category for Les Chants de la Walkyrie, the first volume of the cycle La Malédiction de l’Anneau (Belfond editions, 2008 - 2010). He received a bursary for creation from the Centre National du Livre for his writing. Valeurs Actuelles writes that "Édouard Brasey makes the ancient Nordic sagas sing, the legend of the powerful Ases and the magnificent Vanes. A remarkable work that holds together a fantastic narrative and lyric poetry".

By the end of 1936 there were 39 more franchised restaurants, creating a total of 41 Howard Johnson's restaurants. By 1939, there were 107 Howard Johnson's restaurants along American East Coast highways, generating revenues of $10.5 million. In less than 14 years, Johnson directed a franchise network of over 10,000 employees with 170 restaurants, many serving 1.5 million people a year. The unique icons of orange roofs, cupolas, and weather vanes on Howard Johnson properties helped patrons identify the chain's restaurants and motels.

The use of CMCs in gas turbines permit higher turbine inlet temperatures, which improves engine efficiency. Because of the complex shape of stator vanes and turbine blades, the development was first focused on the combustion chamber. In the US, a combustor made of SiC/SiC with a special SiC fiber of enhanced high-temperature stability was successfully tested for 15,000 hours. SiC oxidation was substantially reduced by the use of an oxidation protection coating consisting of several layers of oxides.

The 3-stage Turbine of the GE J79 Because a turbine expands from high to low pressure, there is no such thing as turbine surge or stall. The turbine needs fewer stages than the compressor, mainly because the higher inlet temperature reduces the deltaT/T (and thereby the pressure ratio) of the expansion process. The blades have more curvature and the gas stream velocities are higher. Designers must, however, prevent the turbine blades and vanes from melting in a very high temperature and stress environment.

The locals valued personal privacy, knew Goddard desired his, and when travelers asked where Goddard's facilities were located, they would likely be misdirected. By September 1931, his rockets had the now familiar appearance of a smooth casing with tail-fins. He began experimenting with gyroscopic guidance and made a flight test of such a system in April 1932. A gyroscope mounted on gimbals electrically controlled steering vanes in the exhaust, similar to the system used by the German V-2 over 10 years later.

Two dipole UHF antennas protruded from the top of the sphere on either side of the injection rocket nozzle. Two dipole UHF antennas and a long VLF antenna protruded from the bottom of the sphere. Thermal control was planned to be achieved by a large number of small "propeller blade" devices on the surface of the sphere. The blades themselves were made of reflective material and consist of four vanes that were flush against the surface, covering a black heat-absorbing pattern painted on the sphere.

A more efficient unit is a "variable air volume (VAV) air-handling unit", or VAV. VAVs supply pressurized air to VAV boxes, usually one box per room or area. A VAV air handler can change the pressure to the VAV boxes by changing the speed of a fan or blower with a variable frequency drive or (less efficiently) by moving inlet guide vanes to a fixed-speed fan. The amount of air is determined by the needs of the spaces served by the VAV boxes.

The first stage also had two fixed air vanes for stability during first stage powered flight. The midcourse phase of the trajectory was initiated at RV separation and continued until the terminal phase began. At the beginning of the midcourse phase, the RV was pitched down to orient it for reentry and to reduce its radar cross-section. The midcourse attitude was then controlled by the RV vane control system during atmospheric exit and reentry, and by a reaction control system during exoatmospheric flight.

Mechanics report ice present on the inlet guide vanes, engine cowlings and engine bullet noses, but no ice was found on the aircraft surfaces. A mechanic recommended that the engine anti-icing system be used, but no maintenance was performed on the aircraft in Anchorage. Investigators suspected that ice on the airfoil or transducer may have caused the stall warning to fail. The ice present on the surface of the wings and leading edges could have reduced the angle of attack needed to produce a stall.

Not all weather vanes have pointers. When the wind is sufficiently strong, the head of the arrow or cockerel (or equivalent depending on the chosen design) will indicate the direction from which the wind is blowing. The weather vane was independently invented in ancient China and Greece around the same time during the 2nd century BCE. The earliest written reference to a weather vane appears in the Huainanzi, and a weather vane was fitted on top of the Tower of the Winds in Athens.

Another unique feature of Iskander-M is the optically guided warhead, which can also be controlled by encrypted radio transmission, including such as those from AWACS or UAV. The electro- optical guidance system provides a self-homing capability. The missile's on- board computer receives images of the target, then locks onto the target with its sight and descends towards it at supersonic speed. Boost phase thrust vector control (TVC) is accomplished by graphite vanes similar in layout to the V-2 and Scud series tactical ballistic missiles.

The shear vane consists of a straight rod with four vanes on one end, arranged in a cruciform pattern, and a combined handle/torque gauge. The rod is inserted into the soil to a depth of 500mm and rotated at a rate of between 6 and 12 degrees per minute. Once the soil fails in shear the gauge shows the maximum torque applied. The gauge is marked with a scale that converts the torque into a shear strength (measured in kiloNewtons per square metre).

The Wagon Wheel Motel and Restaurant was an example of American roadside architecture from the mid-century. The ranch-style office, motel and restaurant were originally built on the side of Highway 101 and Highway 101A (Alternate) in 1947. The office/restaurant complex incorporated a variety of roof lines, primarily low to medium pitched gables covered with wood shingles and punctuated by several decorative cupolas with weather vanes, and neon lighting. A free-standing 12-unit, two-story motel addition was completed in 1953.

C. lyra is named the harp sponge because its basic structure resembles a Lyre. It is a sessile organism which anchors itself to the soft seafloor using a rhizoid, a root-like structure that embeds into the sea floor. From the top of the rhizoid, 1 to 6 horizontal, equidistant stolons with vertical branches form the 'vanes' of the sponge (this is evident in all of Chondrocladia). Stolons vary from being straight to curved, often with mixtures of straight and curved stolons in the same specimen.

Upper and lower wings were braced by outward leaning duralumin N-form interplane struts; the lower wing was mounted on the lower fuselage and the upper one joined to the upper fuselage with outward leaning, parallel pairs of cabane struts on each side. Wire bracing completed the structure. The V-12 Hispano engine was mounted in the nose behind a large radiator fitted with vanes to control the engine temperature. The engine mounting and the rest of the fuselage structure was built from molybdenum-chrome steel tubes.

The elbow divides the flow unevenly with more channeled to the outside of the elbow. Consequently, one side of the double-suction impeller receives more flow at a higher flow velocity and pressure while the starved side receives a highly turbulent and potentially damaging flow. This degrades overall pump performance (delivered head, flow and power consumption) and causes axial imbalance which shortens seal, bearing and impeller life.Pulp & Paper (1992), Daishowa Reduces Pump Maintenance by Installing Fluid Rotating Vanes To overcome cavitation: Increase suction pressure if possible.

In this application, the heat is provided by a large area of ground heated by the sun and covered by a transparent surface that traps hot air, in the manner of a greenhouse. A vortex is created by deflecting vanes set at an angle relative to the tangent of the outer radius of the solar collector. Louat estimated that the minimum diameter of the solar collector would need to be 44+ metres in order to collect "useful energy". A similar proposal is to eliminate the transparent cover.

Most currently operational vectored thrust aircraft use turbofans with rotating nozzles or vanes to deflect the exhaust stream. This method can successfully deflect thrust through as much as 90 degrees, relative to the aircraft centerline. However, the engine must be sized for vertical lift, rather than normal flight, which results in a weight penalty. Afterburning (or Plenum Chamber Burning, PCB, in the bypass stream) is difficult to incorporate and is impractical for take-off and landing thrust vectoring, because the very hot exhaust can damage runway surfaces.

Boyd's Windmill, also known as Boyd's Wind Grist Mill, is a historic smock mill at Paradise Valley Park on Prospect Avenue in Middletown, Rhode Island. John Peterson built the windmill on Old Mill Lane in Portsmouth, Rhode Island in 1810, and William Boyd purchased it in 1815. It originally had four common sails, but four more were added by the family. The mill is a timber-frame structure, octagonal in shape, and about tall, with a rotating cap powered by eight vanes with canvas sheets.

One cannon can be fired per turn, which is done by adjusting the firing angle and amount of powder. An additional challenge is generated by the wind, which changes its strength each turn. The game also simulates a simple economy system: Prices to replenish the stock of balls and powder and replace destroyed cannons and vanes alter each turn. You have the possibility to build (destroyable) derricks for more income and can raise or lower taxes, which will be reflected in the morale of your people.

Police also informed investigators of the registration details, which were quickly traced to the car's owner, Paul Charles Denyer. Detectives visited her small unit at 186 Frankston‑Dandenong Road, Seaford, the afternoon of 31 July - a unit shared with Denyer's girlfriend, and next door to Donna Vanes' sister. While her movements were being checked, she admitted to being in the vicinity of the Fream and Russell murders at the time. She was then taken to Frankston Police Station, and her videoed interview commenced at 9:20pm.

This can be achieved with control vanes, movement of individual sails, movement of a control mass, or altering reflectivity. Holding a constant attitude requires that the ACS maintain a net torque of zero on the craft. The total force and torque on a sail, or set of sails, is not constant along a trajectory. The force changes with solar distance and sail angle, which changes the billow in the sail and deflects some elements of the supporting structure, resulting in changes in the sail force and torque.

Liquid-ring pump A liquid-ring pump is a rotating positive-displacement pump. They are typically used as a vacuum pump, but can also be used as a gas compressor. The function of a liquid-ring pump is similar to a rotary vane pump, with the difference being that the vanes are an integral part of the rotor and churn a rotating ring of liquid to form the compression-chamber seal. They are an inherently low-friction design, with the rotor being the only moving part.

There are three vanes - the horizon vane (A), the shadow vane (B) and the sighting vane (C). The sun casts that shadow of a vane (B in the adjacent image) on a horizon vane (A). The horizon vane has a slit or hole to allow the observer to see the horizon in the distance. The observer aligns the horizon and shadow so they show at the same point on the horizon vane and sets the sighting vane (C) to align his line of sight with the horizon.

The Pfund telescope, originated by A.H. Pfund, provides an alternative method for achieving a fixed telescope focal point in space regardless of where the telescope line of sight is pointed. Pfund's configuration uses a two-axis flat feed mirror that reflects starlight into a fixed paraboloidal mirror, usually with a horizontal optical axis. The paraboloid focuses through a central hole in the feed flat to a convenient location some distance behind the flat. No spider vanes or Newtonian secondary fold mirrors are required in this configuration.

The 1,300 shp Advanced Turboprop could be extended in an 850 to 1,600 shp range. Its 16:1 overall pressure ratio allow a 20% lower fuel burn and 10% higher cruise power than same size class competition with a 4000–6000 hour mean time between overhauls (MTBO). The compressor is derived from the General Electric T700 with four axial stages and a single centrifugal stage, with the same 3D aerodynamics design used in the GE9X. The engine include variable stator vanes (VSVs) and 3D printed parts.

Usually sites are screened on the basis of a wind atlas, and validated with on-site wind measurements via long term or permanent meteorological-tower data using anemometers and wind vanes. Meteorological wind data alone is usually not sufficient for accurate siting of a large wind power project. Collection of site specific data for wind speed and direction is crucial to determining site potentialWind energy-- the facts: a guide to the technology, economics and future of wind power page 32 EWEA 2009.

The toes are anisodactyl—three forward, one back—like those of most birds, but the chimney swift can swivel its back toe (its hallux) forward to help it get a better grip. Unlike the legs and feet of most birds, those of the chimney swift have no scales; instead, they are covered with smooth skin. Its tail is short and square, measuring only in length. All ten of its tail feathers have shafts which extend as much as beyond the vanes, ending in sharp, stiff points.

It was determined that an autopilot guidance system was required and that a means of radio guidance to control roll, pitch and yaw, would also be needed. Graphic mapping of the missile’s flight would be performed by two radar plotting boards. The guidance system of the first few rounds of Corporal E were to be supplied by Sperry Gyroscope Company largely from existing units because of the time required to develop special units. Primary control was to be via vanes extending into the rocket exhaust.

Historically, Co-based superalloys have depended on carbide precipitation and solid solution strengthening for mechanical properties. While these strengthening mechanisms are inferior to gamma prime (γ') precipitation strengthening, cobalt has a higher melting point than currently ubiquitous nickel-based superalloys and has superior hot corrosion resistance and thermal fatigue. As a result, carbide-strengthened Co-based superalloys are used in lower stress, higher temperature applications such as stationary vanes in gas turbines. However, recent research has shown that cobalt can exhibit the γ' phase.

The company produced gates, railings, and other features including weather vanes and shop sign. Hadden's work for Robert Lorimer included the wrought iron gates for the Thistle Chapel in St Giles' Cathedral, Edinburgh (1911), and the casket for the Scottish National War Memorial in Edinburgh (1927). Other commissions included railings for Lord Carmichael's house in Skirling. After the Second World War, commissions by the firm included the Quincentenery gates for the University of Glasgow (1952) and the memorial gates for George Heriot's School (1959).

With the greater soot production, EGR is often combined with a particulate matter (PM) filter in the exhaust.Bennett, Sean (2004). Medium/Heavy Duty Truck Engines, Fuel & Computerized Management Systems 2nd Edition, . In turbocharged engines, EGR needs a controlled pressure differential across the exhaust manifold and intake manifold, which can be met by such engineering as use of a variable geometry turbocharger, which has inlet guide vanes on the turbine to build exhaust backpressure in the exhaust manifold directing exhaust gas to the intake manifold.

Adamson and Folland, p. 276 His forceful speech on 2 December suggesting that the king would need to be eliminated as a political force was opposed by others, including Nathaniel Fiennes, who claimed that the concessions the king had made to date were sufficient that an agreement might be reached. Others suggested that rather than dividing the house by opposition to the king, it be divided by separating those who had gained in the war from those who had not, and that financial contributions be made from one group to the other.Adamson and Folland, p. 277 After an impassioned conciliatory speech by William Prynne, Parliament finally voted on 5 December that the king's concessions were sufficient, but Clement Walker and other opponents of Vane whispered that both Vanes had abused their positions of power during the war for profit. Walker compiled a long list of MPs he claimed had acted corruptly, but Vane was not on it. Instead, Walker charged the Vanes with benefiting by buying at a discount "sleeping pensions", or debts owed by the public purse to individuals, and then pursuing payment of them to enrich themselves.

The AMR Pro package for the Vulcan was unveiled at the 2017 Goodwood Festival of Speed. The package contains extra aerodynamic pieces to enhance the performance of the car, with the presence of an enhanced dual-element rear wing with a Gurney flap, large dive planes, side wheel arch louvres, and turning vanes designed to improve steering response. These improvements allow the car's downforce performance to increase by 27%. Balance has been improved as well, with a 47/53 weight distribution, due to the majority of the pressure going towards the centre of the car.

Flowocean is a Swedish technology company with its own proprietary technology for floating offshore wind power with head office in the city of Västerås, Sweden. FLOW is a semi-submersible floating offshore wind turbine technology with two wind turbine generators on one floating platform. The structure weather vanes passively so that the wind turbines always face the wind. Flow technology is a combination of Tension Leg Platform(TLP) and Semi-Submersible which gives the Flow unit the benefits of both principles and allows the unit to be robust and light.

As was also the case for the V-2, hydrogen peroxide was converted to steam to drive the turbopump that fed fuel and oxidizer into the engine. As its V-2 counterpart, it also was regeneratively cooled. Viking pioneered important innovations over the V-2. One of the most significant for rocketry was the use of a gimbaled thrust chamber which could be swiveled from side to side on two axes for pitch and yaw control, dispensing with the inefficient and somewhat fragile graphite vanes in the engine exhaust used by the V-2.

University presentation on JSF Program Inlets on subsonic aircraft are simple and shorter: an opening designed to minimize drag.Inlet Design and Inlet types, NASA. On supersonic military jets, the inlets are usually much more complex and use shock waves to slow the air, and movable internal vanes to shape and control the flow. Supersonic flight speeds form shock waves in the intake system and reduce the recovered pressure at the compressor, so some supersonic intakes use devices, such as a cone or ramp, to increase pressure recovery by making more efficient use of shock waves.

The VL5 was the third moving head wash luminaire to be produced by Vari-lite and was released in September 1992. It uses the Dichro-Tune radial CMY color mixing system (see US Patents 5073847 and 5186536). This system gives smoother transitions between colours and more even pastel shades, than that used in the VL3 and VL4; but is slower in end-to-end travel and gives the fixture the unmistakable black dot at the front of the fixture. A fourth set of vanes carry diffused glass to soften / widen the beam.

The actual pressure exerted by light is far too small to move these vanes but can be measured with devices such as the Nichols radiometer. #Another incorrect theory was that the heat on the dark side was causing the material to outgas, which pushed the radiometer around. This was later effectively disproved by both Schuster's (1876) and Lebedev's (1901) experiments. #A partial explanation is that gas molecules hitting the warmer side of the vane will pick up some of the heat, bouncing off the vane with increased speed.

The thermal creep from the hot side of a vane to the cold side has been demonstrated in a mill with horizontal vanes that have a two tone surface with a black half and a white half. This design is called a Hettner radiometer. This radiometer's angular speed was found to be limited by the behavior of the drag force due to the gas in the vessel more than by the behavior of the thermal creep force. This design does not experience the Einstein effect because the faces are parallel to the temperature gradient.

The machines and drives in the turbine house date back to 1920, when the looms were converted to electric operation. In the basement there is the turbine, guide vanes and water chamber. In the engine room, the large bevel gear wheel, which sits on the turbine axis and is equipped with original wooden teeth from 1920, is set in motion by the rotational force of the turbine. With the small bevel gear wheel and the transmissions, the rotational force is transmitted to the bevel shaft, which drives the generator at 1000 revolutions per minute.

Built in 1920 by Brown, Boveri & Cie, the three-phase synchronous generator with attached exciter machine has an output of 62 kW. At a frequency of 50 Hz it has a speed of 1000 revolutions per minute. In the engine room, the underground guide vanes are controlled by the regulator built by Bell Maschinenfabrik, to which they are connected by a linkage. Once the turbine has been started up with the handwheel, the oil pressure with the centrifugal governor ensures that the desired number of revolutions is constantly maintained.

During the course of the L-2000-2's development, the engine previously selected by Lockheed was no longer deemed acceptable. During the time frame between the L-2000-1 and L-2000-2, Pratt and Whitney designed a new afterburning turbofan called the JTF-17A, which produced greater amounts of thrust. General Electric developed the GE4 which was an afterburning turbojet with variable guide- vanes, which was actually the less powerful of the two at sea level, but produced more power at high altitudes. Both engines required some degree of afterburner during cruise.

Overall the engine had a five-stage compressor providing air at a compression ratio of 3:1 to ten flame cans, which powered a single-stage turbine. The turbine was also unique for the era, using a set of guide vanes that were adjustable for various operating speeds. Like most German axial engines, the engine also included a variable-geometry exhaust cone to lower back pressure when starting, but used an electric starter motor instead of the Riedel piston engine built into both the BMW 003 and Jumo 004.

However, in nanometre-scale applications such as nanoelectromechanical systems (NEMS), the effect of light pressure is more significant, and exploiting light pressure to drive NEMS mechanisms and to flip nanometre-scale physical switches in integrated circuits is an active area of research.See, for example, nano-opto-mechanical systems research at Yale University. At larger scales, light pressure can cause asteroids to spin faster, acting on their irregular shapes as on the vanes of a windmill. The possibility of making solar sails that would accelerate spaceships in space is also under investigation.

City officials moved the weathervane in 1984 and placed it on display in the Aldrich Public Library. With 80 years of weather taking its toll on the hand-hammered copper, the vane received restoration and repairs by a professional conservation firm in 1993. Recent security concerns prompted the city to remove the weathervane from the library. Today, weathervanes are prized as decorative folk art and examples of early American craftsmanship. It is noteworthy that Vermont’s own Shelburne Museum led the way in first collecting and preserving rare and unique vanes from across the country.

Hybrid ceramic bearings are newly configured to deal with loading changes and will cope with higher temperatures. More variable vanes in one IP and four HP compressor stages will be optimised for constant changes through the flight envelope. An air pipe is produced by additive manufacturing and prototype components come from new suppliers. The Advance3 will survey bearing load, water ingestion, noise sources and their mitigation, heat and combustor rumble while blade-tip, internal clearances and adaptive control operation are radiographed in-motion to verify the thermo-mechanical modelling.

The Open Hand Monument is a symbolic structure designed by the architect Le Corbusier and located in the Capitol Complex of the Indian city and union territory of Chandigarh. It is the emblem and symbol of the Government of Chandigarh and symbolizes "the hand to give and the hand to take; peace and prosperity, and the unity of mankind". The largest example of Le Corbusier's many Open Hand sculptures, it stands high. The metal structure with vanes is high, weighs , and was designed to rotate in the wind.

However, the same properties that make it a good solvent for oils also make it a good solvent of undesired things left behind during the manufacturing of a unit. Some of which are: dust, dirt, residue from soldering, small bits of metal from cutting, and oxidized metal from the tubing. The residues collected can clog the system filters and cause excessive wear or damage to critical components such as the vanes or valves. This aspect makes it more important to check that components are machined properly, deburred, and cleaned.

In order to lower the centre of gravity of the device and thus increase its period of motion as a means of stabilizing it, extra brass was usually added to the bottom of the instrument inside the ring. This is clearly evident in the lower left instrument seen in the photograph above. The alidade was free to rotate about a pin through the centre of the instrument. The vanes of the alidade were either slotted or pierced with a hole to allow the user to align the alidade.

The Coléoptère featured a central core akin to the Atar Volant, but differed in that the fuselage was surrounded by an annular wing greatly resembling the proposals made by von Zborowski. Aerodynamic control and stability was regulated by a series of four triangular winglets, which were installed upon the outwards side of the annual wing; however, these were only effective during conventional horizontal flight. Instead, control while hovering was provided by a series of deflecting vanes within the engine exhaust. The undercarriage of the Coléoptère consisted of four relatively compact castored wheels.

However the coming of the Chicago, Burlington and Quincy Railroad to the community combined with the Wabash railroad's decision to move their depot from Cunningham to Sumner gave the latter the upper hand in growth.Historical, Pictorial, & Biographical Record of Chariton County, Missouri, Pictorial and Biographical Publishing Co., Salisbury Missouri, 1896 Sumner was laid out by Joel H. Wilkerson in June, 1882. That fall the first home was constructed in the new village by J.M. Vanes, soon followed by the Commercial Hotel. A newspaper, the Sumner Star, was established in 1890 and operated for several years.

The adult specimen of Epidexipteryx lacked preserved feathers around the forelimbs, but preserved simple feathers on the body and long, ribbon-like feathers on the tail. The tail feathers, likely used in display, consisted of a central shaft (rachis) and unbranched vane (unlike the vanes of modern feathers, which are broken up into smaller filaments or barbs). Yi also preserves feathers. These are notably very simple for a member of Pennaraptora (a clade of which scansoriopterygids are usually considered members), being "paintbrush-like", with long quill-like bases topped by sprays of thinner filaments.

Team Nasamax, an operation based in Sittingbourne, England, entered the first renewable-fuelled sports prototype racing car at the Le Mans event to increase awareness of renewable fuels. The car, called the Reynard 01Q, ran a Cosworth V8 turbocharged engine on bio-ethanol fuel, which does not release carbon dioxide into the atmosphere because it is produced from crops. The car's fuel systems and inlet air system were modified to allow for the efficient combustion of fuel. An alternative exhaust system was built and the housing and vanes on the turbocharger were altered.

Learjet 25 about to take-off Two General Electric CJ610-6 single-rotor axial-flow turbojet engines are pylon-mounted on each side of the aft fuselage. Each engine is rated at 2950 pounds of thrust at sea level. The engine compartments consist of an eight- stage axial-flow compressor directly coupled to a two-stage turbine, a through-flow annular combustion system, variable inlet guide vanes, controlled compressor interstage bleed, exhaust nozzle and accessory drive system. Starting ignition is provided by a dual output capacitor-discharge system.

The control system was found to be unable to keep the rocket from turning with a wind greater than 12 feet per second. The stable platform gyros were limited to a 30 degree range of motion, and when the platform tumbled, the parachutes deployed. Additionally, the jet vanes needed to move faster, and have a larger control force, to stop the rolling. Finally, the fins were redesigned in the A-5, when it was realized an expanding jet plume as the rocket gained altitude, would have destroyed the A-3 fin stabilizing antenna ring.

The old steam propulsion system required astern turbines to move the ship backwards or stop her moving forward. The pitch of the new variable pitch blades could simply be reversed, causing a reversal of propeller thrust while maintaining the same direction of propeller rotation, allowing the ship shorter stopping times and improved handling characteristics. The new propellers were originally fitted with "Grim Wheels", named after their inventor, Dr. Ing Otto Grim. These were free-spinning propeller blades fitted behind the main propellers, with long vanes protruding from the centre hub.

Microwave radiometers operate in the microwave wavelengths. While the term radiometer can refer to any device that measures electromagnetic radiation (e.g. light), the term is often used to refer specifically to a Crookes radiometer ("light-mill"), a device invented in 1873 in which a rotor (having vanes which are dark on one side, and light on the other) in a partial vacuum spins when exposed to light. A common belief (one originally held even by Crookes) is that the momentum of the absorbed light on the black faces makes the radiometer operate.

The primary air flow containing the particulates enters from the bottom of the cyclone and is forced into spiral rotation by stationary spinner vanes. The secondary air flow enters from the top of the cyclone and moves downward toward the bottom, intercepting the particulate from the primary air. The secondary air flow also allows the collector to optionally be mounted horizontally, because it pushes the particulate toward the collection area, and does not rely solely on gravity to perform this function. Large scale cyclones are used in sawmills to remove sawdust from extracted air.

Air handlers typically employ a large squirrel cage blower driven by an AC induction electric motor to move the air. The blower may operate at a single speed, offer a variety of set speeds, or be driven by a variable-frequency drive to allow a wide range of air flow rates. Flow rate may also be controlled by inlet vanes or outlet dampers on the fan. Some residential air handlers in USA (central "furnaces" or "air conditioners") use a brushless DC electric motor that has variable speed capabilities.

It weighs with its custom pylon and wing strengthening, compared to for the CF6-80C2s and its pylon. In February 2018, the GE9X's first flight was delayed by problems discovered in the HPC variable stator vanes (VSV) lever arms. These are to be changed for the production engine, but will not affect its flow. Also a routine A Check discovered fan-case corrosion and HP turbine airfoils limits on the 747 testbed's CF6 engines. It first flew on March 13 with the previous design of the VSV external lever arm.

As the aircraft takes off, the airflow pushes the paddle parallel to the fuselage and the plate is moved underneath the stairway, preventing it from being lowered. Once the airflow decreases on landing, the spring-loaded paddle returns to its initial position, thereby allowing the stairs to be lowered again. Although this device was intended to prevent hijackings aboard the 727 and other aircraft with a ventral airstair, many airlines sealed the airstair entirely, never to use it again. McDonnell Douglas DC-9 aircraft with ventral stairs were also equipped with Cooper vanes.

An axial- flow waterjet's pressure is increased by diffusing the flow as it passes through the impeller blades and stator vanes. The pump nozzle then converts this pressure energy into velocity, thus producing thrust. Axial-flow waterjets produce high volumes at lower velocity, making them well suited to larger low to medium speed craft, the exception being personal water craft, where the high water volumes create tremendous thrust and acceleration as well as high top speeds. But these craft also have high power-to-weight ratios compared to most marine craft.

Polmar, p. 521 VLS tube The NSPO also used the M series upgrade as an opportunity to upgrade the system to allow it to be launched from a Vertical Launching System (VLS). This modification uses the "Jet Vane Control" (JVC) package that is added to the bottom of the missile. On launch, a small engine in the JVC boosts the missile up above the launching ship, then uses vanes positioned in its own exhaust to quickly slew the missile into the proper alignment with the target, which is fed to the JVC during launch.

A glide mode trajectory consists of two phases: a ballistic phase and a glide phase. At a predetermined point along the trajectory, the guidance vanes extend and there is a transition from ballistic phase to glide phase. Glide phase targeting logic is designed to ensure the largest possible angle of fall permitted by the cloud cover and the visibility. The target is acquired when the projectile is close enough to detect the laser illumination or when the projectile emerges from the cloud cover, whichever event occurs later in the trajectory.

If pressure drops further, which can happen locally near the vanes for the pump, for example, then a phase change can occur and gas will be present in the pump. Similar effects can also occur on marine propellors; wherever it occurs, it is a serious problem for designers. When the vapor bubble collapses, it can produce very large pressure spikes, which over time will cause damage on the propellor or turbine. The above two-phase flow cases are for a single fluid occurring by itself as two different phases, such as steam and water.

Dethridge wheel in 1936 - Victoria Australia An ornamental Dethridge wheel at Finley, New South Wales The Dethridge wheel is used throughout Australia and in many other countries, including the United States, Israel and in Africa, to measure the flow of water delivered to farms for irrigation. The wheel was invented by John Dethridge in Australia in 1910. Dethridge was then commissioner for the State Rivers and Water Supply Commission of Victoria. The wheel consists of a drum on an axle, with eight v-shaped vanes fixed to the outside.

Microraptor had four wings, one on each of its forelimbs and hindlimbs, somewhat resembling one possible arrangement of the quartet of flight surfaces on a tandem wing aircraft of today. It had long pennaceous feathers on arms and hands with legs and feet . The long feathers on the legs of Microraptor were true flight feathers as seen in modern birds, with asymmetrical vanes on the arm, leg, and tail feathers. As in modern bird wings, Microraptor had both primary (anchored to the hand) and secondary (anchored to the arm) flight feathers.

The IUCN, following the precautionary principle, listed this taxon as extinct until 2012. It was removed from the IUCN Red list because the IOC had removed this species from its list of valid bird taxa in 2011. While the feather is indeed quite distinct, it represents a fairly simple divergence: The entirely asymmetrically-patterned vanes are instead near-symmetrical, and both bear the darker brown shaftward area with dense whitish speckles. The shaft is thinner than usual and the feather would probably not have been useful for flight.

The volume is vertically dominant, covered by a terrace on its top. By the stereotomy of the stonework it is evident that the a framed balcony span had been constructed without taipa (common at the time) with the use of great stones. The old municipal house was a regular granite structure, with grated doors in the west and north, with a northern elevation accessible by ramp. The western portico is demarcated by its facade and remnants of two vanes, with battlements and projected frame with lateral rectangular grille window.

Since the engines did not have to be warmed up, the XH-26 could take off in 30 seconds. The pulse jets produced no torque, and the tiny, belt-driven tail rotor was used only to improve directional control. The only mechanical item that had to be replaced after so many hours of flight was the intake air vanes, which were small and inexpensive and could be replaced with a small tool in minutes. American Helicopter chose the name "Jet Jeep", because the XH-26 could be used like a Jeep, but in the air.

Four guide vanes held the cone in place, with two power takeoff shafts running inside two of them to power the top- and bottom-mounted accessories section (fuel pumps, oil pumps). The nose cone also held the electric starter motor, which acted as a generator once the engine was up and running. The engines used on the CF-100 also contained a uniquely Canadian invention, two prominent winglettes at the very front that sprayed alcohol into the intake as a de-icing system. The CF-100 versions also mounted the debris cage, mentioned earlier.

The most common form of hush kit is a multi-lobe exhaust mixer. This device is fitted to the rear of the engine and mixes the jet core's exhaust gases with the surrounding air and a small amount of available bypass air. Modern high-bypass turbofan engines build on this principle by utilizing available bypass air to envelop the jet-core exhaust at the rear of the engine, reducing noise. Most hush kits make further modifications to the exhaust, including acoustically treated tailpipes, revised inlet nacelles and guide vanes.

Crossing tower, nave and southern transept, seen across the bible garden (former cloister) The lower storeys of the northern tower may be original The cathedral has twin 89 meter towers (with weather-vanes 92.31 mWalter Born: Die hohen deutschen Kirchtürme, , Hildesheim: Lax 1979. Die Höhenangaben basieren auf amtlichen Vermessungen.) referred to as the north tower and the south tower. Like several major romanesque churches, Bremen Cathedral has a second choir in the west. The towers were constructed flanking this western choir, forming the west front of the church since 1215 and 1253.

Hudson Memorial seen behind the Memorial Obelisk raised for the Men who fell in the Siege of Bangalore, 1791. (The memorial was vandalised on 28 October 1964) The congregation of the Canarese Wesleyan Chapel soon grew to 250, and the present building was congested. Hence a need rose to look for a large plot of land to build a bigger church. At the time, a certain Dr. Aayachamma who was related to Dr. Arokyam Pillay, sold the land of present church to Rev J A Vanes on 19 January 1900, for INR 2000.

For increasing or decreasing overall lift, the angle of attack for all blades is collectively altered by equal amounts at the same time resulting in ascents, descents. The Fancraft technology on the AirMule employs a Vane Control System (VCS)(US Patents #6,464,166 and 6,817,570) consisting of 200 vanes at the inlet and outlet ducts that can be deflected simultaneously (top and bottom) or differentially to generate side force or a rolling movement. Front and rear ducts are deflected differentially for yaw. The VCS generates six degrees of freedom independent of one another.

The engine was difficult to start, would not accelerate and broke first-stage blades. Two-position inlet guide vanes and compressor bleed were among the design changes which allowed the engine, as the RA.2, to run a 25-hour test and fly in the two outboard positions on the converted Avro Lancastrian military serial VM732, from Hucknall on 15 August 1948. The first production engine, which needed a two-stage turbine, was the RA.3, or Avon Mk 101. Several modified versions of this design were produced in the Mk. 100 series.

Another change addressed the Sapphire's only major problem. The Sapphire was found to work well through the entire RPM range without the compressor stalling, which allowed it to dispense with inlet guide vanes or other solutions found on contemporary designs. However, in service it was found that while pressure was maintained even at low speeds and RPM, the first stages were stalling and this was causing significant vibration and fatigue issues. Wright solved this by adding inlet ramps that closed off the outer portions of the intake at low RPM.

The SPAS 13 was a development of the earlier SPAS 1 and was designed to demonstrate the advantages of a spherical airship. The 43 ft (13.11 m) diameter spherical envelope is made of Spectra fabric with an inner helium containing envelope of Mylar film reinforced with Kevlar. The two-seat cockpit is internal to the envelope with panoramic windows in the envelope to provide an external view. The SPAS 13 is powered by two Rotax 503 piston engines on external struts, four vanes behind each engine are used to provide control by deflecting the thrust.

A Lebert Éolienne, Rugles, Eure Lebert built some very similar wind engines with a single rotor, and lacking the stator (thus they were not true turbines). They were either or diameter. At least three of these are known to have been built, including at Rugles, Eure and Parigné-l'Évêque, Sarthe. The Clarkson wind engine consisted of a rotor or a number of rotors, one behind the other, revolving in a casing with fixed guide vanes between and of opposite pitch to those of the rotors, and having a further casing to admit a fresh supply of wind to the rotors behind.

This has made it a popular choice for television lighting and other noise-sensitive applications. The VL5 Arc introduced a 575W discharge lamp to the design. As this could not be electronically dimmed, the diffuser vanes were replaced with black metal ones, which acted as a mechanical dimmer. Beam width control was initially carried out using an innovative "Liquid Lens"—again designed by Jim Bornhorst (see US Patent 5774273)—which pumped a liquid silica-based gel into a series of lentil-shaped cavities, set between two plastic membranes—thus altering their refractive index and giving a variable beam angle of 13–34°.

Two triangular shaped retractable surfaces, called glove vanes, were originally mounted in the forward part of the wing glove, and could be automatically extended by the flight control system at high Mach numbers. They were used to generate additional lift (force) ahead of the aircraft's center of gravity, thus helping to compensate for mach tuck at supersonic speeds. Automatically deployed at above Mach 1.4, they allowed the F-14 to pull 7.5 g at Mach 2 and could be manually extended with wings swept full aft. They were later disabled, however, owing to their additional weight and complexity.

To rotate, a light mill does not have to be coated with different colors across each vane. In 2009, researchers at the University of Texas, Austin created a monocolored light mill which has four curved vanes; each vane forms a convex and a concave surface. The light mill is uniformly coated by gold nanocrystals, which are a strong light absorber. Upon exposure, due to geometric effect, the convex side of the vane receives more photon energy than the concave side does, and subsequently the gas molecules receive more heat from the convex side than from the concave side.

The zinc casing in the dry cell gets thinner even when the cell is not being used, because the ammonium chloride inside the battery reacts with the zinc. An "inside-out" form with a carbon cup and zinc vanes on the interior, while more leak-resistant, has not been manufactured since the 1960s. Progressive corrosion of zinc–carbon batteries This picture shows the zinc container of fresh batteries at (a), and discharged batteries at (b) and (c). The battery shown at (c) had a polyethylene protection film (mostly removed in the photo) to keep the zinc oxide inside the casing.

This was a recent development in jet engines and the Orpheus also included the innovation of incorporating the turbine entry duct and its stator vanes into the flame tube outlet, each flame tube providing one seventh of the overall duct. This had two advantages, it simplified the manufacture of a complicated and unreliable component, also the segmented design allowed easier allowance for thermal expansion. Developing a Sea Level Static thrust of , the Orpheus 701 had a 7-stage axial compressor driven by a single stage turbine. In 1957 NATO ran a competition for a light fighter design.

In 1986, the twin towers were restored in a project costing £242,000 (now £). The works revealed that the east tower still contained a large water tank which was used during the days of steam traction to replenish locomotives and to power the station's hydraulic systems. The brickwork was repaired, cleaned and repointed, and the weather vanes gilded to complement the dome of nearby St Paul's Cathedral. This work was one of the Railway Heritage Trust's first projects and coincided with an exhibition held in the station in August of the same year to mark its 150th anniversary.

Daimler Double Six (XJ81) Given the model code XJ81, the XJ40-based XJ12 and Daimler Double Six were introduced at the Amsterdam Auto Show in February 1993 and powered by a 6.0-litre version of Jaguar's V12 engine. This was mated to a GM 4L80E 4-speed automatic gearbox. It could be identified by the XJ12 or Double Six badge on the rear and a V12 emblem on the glovebox. The XJ12 used the two twin-headlamp pairs, black radiator grille vanes, and a gold "growler" badge on the radiator grille top, while the Daimler received the rectangular headlamps.

Smoke-jack from Mathematical and Philosophical Works of the Right Rev. John Wilkins (1802) Leonardo da Vinci sketched a smoke-jack in the form of a turbine with four vanes. Smoke-jacks were also illustrated in Vittorio Zonca's book of machines (1607), and in Wilkins's Mathematical Magick. The 1826 A Treatise of Mechanics describes a smoke-jack: > Smoke-jack is an engine used for the same purpose as the common jack; and is > so called from its being moved by means of the smoke, or rarefied air, > ascending the chimney, and striking against the sails of the horizontal > wheel AB (plate XXI.

A more serious attempt was the "Cambrian System" of John Jones in 1841. This design used two or three flat plates that were geared to move closer or further apart as the cycle continued. When the plates were at their closest point, steam was admitted between them using a valve, pushing them apart as the cycle continued. When the plates reached their maximum distance, an internal passage was uncovered that allowed the partially expanded steam to flow across the center of the device into the area on the other side of the vanes, which were now at their minimum distance.

The spin is imparted by small fins at the rear of the rocket body that flip out into the airstream once the rocket leaves its launch tube. The fins take a short time to open, and more time to start the rocket spinning. During this period the rockets can drift significantly from their original aim point. The CRV7 solved this problem by adding small vanes projecting into the rocket exhaust to start the rocket spinning even before it left the launch tube, greatly increasing accuracy. A salvo of CRV7's will impact the target area in one-third the footprint of older designs.

240 Vane was not amused by this, and responded by pointing out that he preferred the rights of "tender consciences" to be granted by Parliament rather than by the duplicitous king (papers exposing the king's negotiating positions as facades had been captured at Naseby, and had largely silenced the Royalist elements in Parliament).Ireland, p. 266 The Vane estates were not spared in the maelstrom of war; Vane's father reported that Raby Castle had been "visited four times", suffering damages of £16,000.Ireland, pp. 243–244 In September 1645, the Vanes succeeded in getting Parliamentary approval to fortify Raby.

Except in some rhea wing feathers, the barb filaments that make up the vanes of the feathers do not lock tightly together, giving the plumage a shaggier look and making it unnecessary to oil their feathers. Adult ratites have no preen gland (uropygial gland) that contains preening oil. Paleognaths as a whole tend to have proportionally small brains, and are among the living birds with the most limited cognitive abilities. Kiwis are exceptional, however, and have large brains comparable to those of parrots and songbirds, though evidence for similar levels of behaviour complexity are currently lacking.

The company was a competitor for the Ansari X-Prize. Armadillo's X-Prize vehicle was unorthodox among modern rockets in that instead of using stabilization fins, which complicate the design and increase drag, Armadillo used an aerodynamically unstable design, where the computer controlled jet vanes based on feedback from fibre optic gyroscopes. Armadillo stated a preference for simplicity and reliability over performance, which was evident in its choice of hydrogen peroxide (50% concentration in water) and methanol as a mixed monopropellant for the vehicle. A monopropellant-based engine requires only a single tank, as well as greatly simplified plumbing and other hardware.

Outdoor vertical wind tunnels may also have walls or netting around the wind column, to keep beginner tunnel flyers from falling out of the tunnel.About.com description Stationary indoor vertical wind tunnels include recirculating and non-recirculating types. Non- recirculating vertical wind tunnels usually suck air through inlets near the bottom of the building, through the bodyflight area, and exhaust through the top of the building. Recirculating wind tunnels form an aerodynamic loop with turning vanes, similar to a scientific wind tunnel, but using a vertical loop with a bodyflight chamber within a vertical part of the loop.

During the time of the French Revolution and the Napoleonic era that followed, the German lands on the Rhine’s left bank were annexed by France. Kirrweiler belonged to the Mairie ("Mayoralty") of Grumbach, the Canton of Grumbach, the Arrondissement of Birkenfeld and the Department of Sarre. Several young men from the village served in the French army. Above Kirrweiler, on the hill known as the "Husarenpötsch" or "Husarenbusch", the French built a rather odd-looking building in 1813, towards the end of the time of French rule, a tall wooden or iron tower with several movable vanes at the top.

Bionier remained fascinated by the shapes and movements of birds and fish. Like some of his contemporaries he had come to appreciate some aerodynamic principles, such as the importance of reducing frontal area and of maintaining smooth, turbulence-free air flow along the length of a car's body. In 1945 he made wooden 1:5 scale models of an experimental car he called the VP6 and had them tested in the wind tunnel of the Institute Aérodynamique in Saint-Cyr. Later, to assess the air flow over full size bodies, he conceived of and manufactured sets of small, light, but precisely shaped vanes.

Leyes, Richard A., and William A. Fleming, The History of North American Small Gas Turbine Aircraft Engines, Smithsonian Institution, Washington, DC, 1999: p.143 In the 1950s, Ryan was a pioneer in jet vertical flight with the X-13 Vertijet, a tail-sitting jet with a delta wing which was not used in production designs. In the early 1960s, Ryan built the XV-5 Vertifan for the U.S. Army, which used wing- and nose-mounted lift vanes for V/STOL vertical flight. It was flown, crashing after ingesting a test rescue dummy in its fans, and was not made into a production aircraft.

Vanes were added to the ends of the longest cross-piece and another to the end of the main staff. The instrument was reversed so that the shadow of the upper vane on the cross piece fell on the vane at the end of the staff. The navigator held the instrument so that he would view the horizon lined up with the lower vane and the vane at the end of the staff. By aligning the horizon with the shadow of the sun on the vane at the end of the staff, the elevation of the sun could be determined.

"Lift-Fan Aircraft-Lessons Learned The Pilot's Perspective" Ronald M. Gerdes, NASA Contractor Report 177620August 1993 The fans provided vertical lift of approximately , nearly three times the thrust of the engines as turbojets. A set of louvered vanes underneath each of the wing fans could vector the thrust fore and aft and provided yaw control. The engine power setting determined the lift from the fans, as fan RPM was determined by the exhaust output from the J85 engines and the load on the fan. Roll control was by differential actuation of the wing-fan exit louvers.

The team went on improving the F1 W07 Hybrid over the course of the season. "S-duct" remains evolved by Mercedes for improving airflow efficiency from the front of the car to the back of the chassis without major disruption. Several improvements were made during the , "L-shaped turning vanes" were introduced under the chassis and beside the bargeboards, front wing fins were added to better direct airflow on the outside of the car’s front wheels. A bowl-shaped rear wing was also introduced during the 2016 Canadian Grand Prix, to allow top speeds in excess of by reducing drag, producing higher downforce.

ISCAR branches exist in over 50 countries worldwide and the company employs nearly 6,000 people. In 1969, as part of Israeli efforts to overcome the French weapons embargo after the Six-Day War, Wertheimer founded ISCAR Blades which later became Blades Technology – one of the largest manufacturers of blades and vanes for jet engines and industrial gas turbines. Today, Blades Technology's customers include Pratt & Whitney, Rolls-Royce, Snecma, General Electric, MTU Aero Engines, Techspace Aero, and Solar Turbines. In May 2006, Berkshire Hathaway bought 80% of ISCAR Metalworking Company for $4 billion (the Wertheimers paid $1 billion in taxes to the Israeli government).

The Meillerwagen carried a number of accessories on the chassis and lifting frame, both for itself and the rocket. A toolbox fixed on the chassis carried snow chains, a tyre pump, and assorted tools for the Meillerwagen and KdF motor. The chassis was equipped with a pair of blast shields, entrenching tools, a hand-steering A-frame, two jacks, a spare tyre and a folding ladder. Special trays were fixed on the chassis to carry the transport cases which held various rocket accessories such as the graphite steering vanes, the nose fuse, and the Z-stoff (permanganate) flask.

By employing thrust vectoring, the engines can direct their thrust downwards to provide additional lift during takeoff. A series of four triangular-shaped variable vanes are positioned behind the engines to provide further control authority by re-directing thrust from the rear engines over the tail fins. While cruising at altitude, propulsion can be switched to a more efficient electric drive fed from the airship's central generator. Due to the hybrid aerostatic/aerodynamic lift approach, fuel can be expended without entering a state of positive buoyancy that would necessitate routine helium venting in order to land, a costly weakness present upon conventional airships.

The tall cauldron was designed by Dr. Tsai Her-Mann, a fellow and resident inventor of the Singapore Science Centre. Designed to look like a lighthouse, its distinctive feature was a swirling column of fire dubbed the "vortex flame" or "fire tornado" inside a tube with an opening at the top end. Hot air that could reach created around the flame rose, drawing cool air upwards from openings in the base of the tower. Just below the glass-panelled portion of the tower, the cool air was driven through angled guide vanes, thus creating the spiralling movement travelling upwards at .

Symbol used in drawings Diagram showing the rod and vane inserted into the soil US Army Corps of Engineers personnel carrying out a shear vane test The shear vane test is a method of measuring the undrained shear strength of a cohesive soil. The test is carried out with equipment consisting of a rod with vanes mounted to it that is inserted into the ground and rotated. A gauge on the top of the rod measures the torque required to cause failure of the soil and provides a conversion to shear strength. The equipment has been in use since at least 1948.

With the 6.7 L Cummins Engine came the introduction of the Variable Geometry Turbocharger (VGT). The VGT Turbocharger was introduced to reduce turbo lag by adjusting the vanes by sliding a steel ring in the exhaust housing dependent on engine RPM creating more or less pressure inside the exhaust housing and controlling the speed of the turbocharger. It also works as an integrated exhaust brake system and is all controlled by an electronic actuator on the turbocharger. This VGT system has been an extremely common issue with the 6.7L Cummins platform and is typically diagnosed by the loss of the trucks exhaust brake.

Meyer Heavy Duty Rotary Airlock Valve thumb Rotary feeders, also known as rotary airlocks or rotary valves, are commonly used in industrial and agricultural applications as a component in a bulk or specialty material handling system. Rotary feeders are primarily used for discharge of bulk solid material from hoppers/bins, receivers, and cyclones into a pressure or vacuum- driven pneumatic conveying system. Components of a rotary feeder include a rotor shaft, housing, head plates, and packing seals and bearings. Rotors have large vanes cast or welded on and are typically driven by small internal combustion engines or electric motors.

During the annual WBC Convention in Kunming, China it was announced that Charlo would fight John Jackson (20-2, 15 KOs) for the vacant WBC light middleweight title. The title became vacant following the retirement of Floyd Mayweather Jr. The fight took place on May 21, 2015 at The Cosmopolitan of Las Vegas, in Las Vegas. The card also included top light middleweight boxers Erislandy Lara, Vanes Martirosyan, Austin Trout and brother Jermall, who successfully defended his IBF title. Through the first 7 rounds, Charlo had only won one round on all three judges scorecards, badly trailing (64-69).

In technical developments, Mercedes installed fins and turning vanes to the F1 W05 Hybrid's lower front wishbone on its front suspension and the rear section of its frontal brake ducts. This was to improve airflow and lessen drag to the inside of the front wheel. Toro Rosso built new exhaust systems for their two cars following the development of fractures from possible overheating that led to their retirements in Monaco. On the FW36, Williams mounted a duct over the top of its brake discs to divert airflow from the main duct to the outside of the caliper.

Nautilus covered the course two minutes faster than the rowing crew. During this time he changed the screw propeller to one with four vanes, like a windmill, and modified the rudder. Through friends like Gaspard Monge and Pierre-Simon Laplace, Fulton obtained an interview with Napoleon, but was unable to garner support for his vessel; however, Fulton's friends pushed the Minister of Marine into appointing a scholarly panel, to consist of Volney, Monge, and Laplace, to assess the submarine. On July 3, 1801, at Le Havre, Fulton took the revised Nautilus down to the then-remarkable depth of .

Red Bull equipped both of their cars with new turning vanes for the Grand Prix in order to improve the airflow underneath the car and therefore create more downforce. The new device had previously only been used by Daniil Kvyat during the previous race in Singapore. After a poor performance in Singapore, Mercedes introduced a revised rear wing endplate, while McLaren brought a new front wing to Suzuka. This was the first running of the Japanese Grand Prix after Jules Bianchi's crash at the previous edition, which proved fatal when Bianchi succumbed to his injuries nine months following the accident.

Wooden rooster whirligig The origin of whirligigs is unknown. Both farmers and sailors use weather vanes on an ongoing basis and the assumption is one or both groups are likely the originators. By 400 BC the bamboo-copter or dragon butterfly, a helicopter-like rotor launched by rolling a stick, had been invented in China. Wind-driven whirligigs were technically possible by 700 AD when the Sasanian Empire began using windmills to lift water for irrigation. The weather vane, which dates to the Sumerians in 1600–1800 BC, is the second component of wind-driven whirligigs.

In the United States, following three hijackings in 1972, the Federal Aviation Administration ordered that Boeing 727 aircraft be fitted with Cooper vanes. The device was named for an unidentified airplane hijacker dubbed D. B. Cooper, who used the rear stairway to exit a Boeing 727 in flight and make his escape via parachute. The Cooper vane is a very simple device consisting of a spring-loaded paddle connected to a plate. When the aircraft is on the ramp, the spring keeps the paddle perpendicular to the fuselage, and the attached plate does not block the stairway.

To load, the bow is pointed toward the ground, tipped slightly clockwise of vertical (for a right handed shooter) and the shaft of the arrow is placed on the arrow rest or shelf. The back of the arrow is attached to the bowstring with the nock (a small locking groove located at the proximal end of the arrow). This step is called "nocking the arrow". Typical arrows with three vanes should be oriented such that a single vane, the "cock feather", is pointing away from the bow, to improve the clearance of the arrow as it passes the arrow rest.

The scapulars (shoulder feathers) are white, and the wings are black with a white bar made up by the bases of the primary remiges, continuing slightly offset onto the bases of the secondary remiges in some regions. The tail is black, long, and pointed at the tip; the outer rectrices have white outer vanes. The underparts are white, slightly tinged with grey in most subspecies. In particular the breast is usually darker and sometimes browner than the rest of the light underside, and may appear as an indistinct band between the lighter belly and white throat.

The most common configuration in all cultures is three fletches, though as many as six have been used. Two makes the arrow unstable in flight. When the arrow is three- fletched, the fletches are equally spaced around the shaft, with one placed such that it is perpendicular to the bow when nocked on the string, though variations are seen with modern equipment, especially when using the modern spin vanes. This fletch is called the "index fletch" or "cock feather" (also known as "the odd vane out" or "the nocking vane"), and the others are sometimes called the "hen feathers".

The grindstones in the middle of the mill are Fall River granite; the upper one, which is connected to the power mechanisms, rotates six times for each turn of the mill's main shaft. In 1916 Benjamin Boyd removed the original vanes and powered the mill using a gasoline engine. It is one of only two historic windmills (out of what was estimated to be more than thirty) to survive on Aquidneck Island. The windmill was restored by the Middletown Historical Society after receiving it as a donation in 1990 and moving it to Paradise Valley Park in Middletown.

Restoration of C. zoui Holotype of C. zoui, with feather impressions and stomach content preserved, Geological Museum of China The hands of Caudipteryx supported symmetrical, pennaceous feathers that had vanes and barbs, and that measured between long. These primary feathers were arranged in a wing-like fan along the second finger, just like primary feathers of birds and other maniraptorans. No fossil of Caudipteryx zoui preserves any secondary feathers attached to the forearms, as found in dromaeosaurids, Archaeopteryx and modern birds. Either these arm feathers are not preserved, or they were not present on Caudipteryx in life.

Label is an older term for a long, thin device, in particular the rule on an astrolabe, circumferentor or similar instrument. It differs from an alidade in that it has no sighting vanes on it. In this latter detail, Elton's use of the term may be inappropriate. The label is an arm that extends from the centre of the arc to the outside of the upper triangle and can be set to one of the three positions in the triangle (in the diagram, it appears to bisect the triangle as it is set to the centre or 30° position).

Pivoting-door thrust reversal seen on the CFM-56 engines of an Airbus A340-300 In addition to the two types used on turbojet and low-bypass turbofan engines, a third type of thrust reverser is found on some high-bypass turbofan engines. Doors in the bypass duct are used to redirect the air that is accelerated by the engine's fan section but does not pass through the combustion chamber (called bypass air) such that it provides reverse thrust. The cold stream reverser system is activated by an air motor. During normal operation, the reverse thrust vanes are blocked.

In 1830 a pump having a fairly good efficiency was built by McCarty at the dock yards of New York. About 1846 centrifugal pumps began to be manufactured in England by Appold Thompson and Gwynne. Appold improved the pump by the addition of curved vanes in 1849.

These used a lever arm which moved hydraulically damped vanes inside the unit. The main advantage over the friction disk dampers was that it would resist sudden movement but allow slow movement, whereas the rotary friction dampers tended to stick and then offer the same resistance regardless of speed of movement. There appears to have been little progress on commercialising the lever arm shock absorbers until after World War I, after which they came into widespread use, for example as standard equipment on the 1927 Ford Model A and manufactured by Houde Engineering Corporation of Buffalo, NY.

Black Chocobos, which sometimes possess the ability to fly, are found in Final Fantasy IV, V, VII, XI, XII, XIV, Final Fantasy Tactics, Final Fantasy Tactics A2, and Final Fantasy Fables: Chocobo's Dungeon. Final Fantasy Mystic Quest features several chocobo-shaped weather vanes in the town of Windia. In Final Fantasy Crystal Chronicles one can obtain the Chocobo Shield and the Chocobo Pocket items, and are included in Final Fantasy Crystal Chronicles: The Crystal Bearers. In the animated sequel to Final Fantasy V, Final Fantasy: Legend of the Crystals, one of the main characters can summon pink, featherless chocobos.

The Kolibri was built as a cylinder with rotors at one or both ends, using vanes moved through the rotor airflow by piezoelectric actuators for flight control. It was powered by electric motors or a tiny, highly efficient multi-fuel engine developed by a company named D-STAR. ;Micro Craft "SLADF" ducted fan micro- helicopter :The Small Lift Augmented Ducted Fan (SLADF) ducted-fan micro- helicopter, built by Micro Craft of San Diego, California, and Ontario, Canada. The SLADF was a ducted fan helicopter with a diameter of about 15 centimeters (6 inches) and a weight of 1.8 kilograms (4 pounds), with payload.

The Twister supersonic separator is a compact tubular device which is used for removing water and/or hydrocarbon dewpointing of natural gas. The principle of operation is similar to the near isentropic Brayton cycle of a turboexpander. The gas is accelerated to supersonic velocities within the tube using a De Laval nozzle and inlet guide vanes spin the gas around an inner-body which creates the "ballerina effect" and centrifugally separates the water and liquids in the tube. Hydrates do not form in the Twister tube due to the very short residence time of the gas in the tube (around 2 milliseconds).

The materials used in the construction are, for the most part, the red brick and, in the background, the stone, reserved for the doorways, the pediments and the socket, the latter of ashlar is granite. The roofs are made in Arabic tiles. The whole is crowned by two small towers located at the ends, on the roofs, which emulate the layout of the original Palace of the Two Towers, on which the current building was erected. They are quadrangular and serve as light bodies, although they have oval vanes that break the linearity of the general layout.

In 1906, an aerial ropeway was installed to lift waste rock from the bottom of the exit incline up the mountainside to a site south-west of the quarry reservoir. A stationary steam engine at the upper end of the ropeway provided the power. By 1909, employment at Llwyngwern was down to 33, and the company sold the lease to Sydney Fowler Wright. But Wright was unable to pay the lease due on the quarry and in early 1910 the owners, the Vanes Estate, closed the quarry and forced an auction of the equipment to recover the money owed to them.

The development of the J58 brought with it some of the most challenging metallurgical development problems experienced by Pratt & Whitney Aircraft up to that time with components operating at unprecedented levels of temperature, stress and durability. New manufacturing techniques as well as new alloys improved the mechanical properties and surface coatings had to be developed to protect component surfaces. Premature cracking of turbine vanes and blades made from what was then conventionally-cast (i.e. equiaxed) Mar-M200, the strongest of the cast nickel-base alloys, was avoided with the development of directionally solidified parts cast in the same material.

The 1977 loss of Southern Airways Flight 242, a McDonnell Douglas DC-9-9-31, while penetrating a thunderstorm cell over Georgia was attributed to compressor stalls brought on by ingestion of large quantities of water and hail. The stalls caused blades to clash with stationary vanes in both of its Pratt & Whitney JT8D-9 turbofan engines. The stalls were so severe as to cause the destruction of the engines, leaving the flight crew with no choice but to make an emergency landing on a public road, killing 62 passengers and another eight people on the ground.

They added two fixed half-moon shaped vertical vanes (called "blinkers") between the elevators (but later removed) and widened the skid- undercarriage which helped give the wings a very slight dihedral. They disconnected the rudder of the rebuilt Flyer III from the wing-warping control, and as in most future aircraft, placed it on a separate control handle. They also installed a larger fuel tank and mounted two radiators on front and back struts for extra coolant to the engine for the anticipated lengthy duration flights. When testing of Flyer III resumed in September, improvement was obvious.

The ultrathin 'sail' material is only 5 μm thick with a low weight of about 32 kilograms (70 lb). Once in space, the large surface area of the solar sail will allow it to achieve a thrust of about 0.01 N. To control its orientation, via this its speed and direction, Sunjammer will use gimballed vanes (each of which is itself a small solar sail) located at the tips of each of its 4 booms completely eliminating the need for standard propellant. On October 17, 2014, NASA cancelled the Sunjammer project after investing four years and more than $21 million on the project.

This can be accomplished by gimballing the nozzle, as in the Space Shuttle SRBs, by the use of jet vanes in the exhaust as in the V-2 rocket, or by liquid injection thrust vectoring (LITV). An early Minuteman first stage used a single motor with four gimballed nozzles to provide pitch, yaw, and roll control. LITV consists of injecting a liquid into the exhaust stream after the nozzle throat. The liquid then vaporizes, and in most cases chemically reacts, adding mass flow to one side of the exhaust stream and thus providing a control moment.

Each of the three spires supports a Celtic cross, a reference to Saint Patrick, seen as a foundational ancestor by both Irish Catholics and Protestants. This inclusion was an implicit statement of national identity, but was against Burges' wishes. His initial design included weather vanes, a choice rejected by the building committee, who, according to the historian Antóin O'Callaghan, wanted the church to "retain the continuity with the one true faith of the ancient past". The spires had a troubled construction: it was a difficult build from a technical point of view and thus expensive to fund.

These either consist of cups that swing across the end of the exhaust nozzle and deflect the jet thrust forwards (as in the DC-9), or they are two panels behind the cowling that slide backward and reverse only the fan thrust (the fan produces the majority of the thrust). Fan air redirection is performed by devices called "blocker doors" and "cascade vanes". This is the case on many large aircraft such as the 747, C-17, KC-10, etc. If you are on an aircraft and you hear the engines increasing in power after landing, it is usually because the thrust reversers are deployed.

An engine is said to be running off-design if any of the following apply: :a) change of throttle setting :b) change of altitude :c) change of flight speed :d) change of climate :e) change of installation (e.g. customer bleed or power off-take or intake pressure recovery) :f) change in geometry Although each off-design point is effectively a design point calculation, the resulting cycle (normally) has the same turbine and nozzle geometry as that at the engine design point. Obviously the final nozzle cannot be over or underfilled with flow. This rule also applies to the turbine nozzle guide vanes, which act like small nozzles.

Hani ships such as The Pride of Chanur are based on mahendo'sat technology. The dock grapples are at the prow of the ship. Behind it is the habitat area with a rotating carousel which provides "gravity" during inertial flight and in jump; the bridge, galley and living quarters - including crew and passenger quarters - are all located in that ring. Then come the pressurized and "cold" holds for cargo canisters, loading machinery and a separate cargo access hatch; then the jump drive assembly with three vanes constructed of modular panels and mounted on support columns, with wire struts; these form the "hyperspace bubble" needed to cross the interface.

For stealth, the F-22 carries weapons in internal bays. The doors for the center and side bays are open; the six LAU-142/A AMRAAM Vertical Eject Launchers (AVEL) are visible. The F-22 was designed to be highly difficult to detect and track by radar. Measures to reduce radar cross-section (RCS) include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets and curved vanes that prevent line-of- sight of the engine faces and turbines from any exterior view, use of radar- absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return.

If these limits are further exceeded (PALL and PAHH) an automatic shutdown of the system is initiated which includes closure of the inlet valves of the vessel. The pressure sensor (PT) that initiates a shutdown is a separate instrument loop from the PT associated with the pressure control loop to mitigate common mode failures and to ensure greater reliability of the shutdown function. The operation of hydrocyclones is controlled by pressure instrumentation that maintains fixed differential pressures between the inlet and the oil and water outlets. Turbo-expanders are controlled by maintaining the inlet pressure (PIC) at a constant value by controlling the angle of the expander inlet vanes.

Researchers from the University of Twente, the University of Patras in Greece, and the Foundation for Fundamental Research on Matter have constructed a Feynman–Smoluchowski engine which, when not in thermal equilibrium, converts pseudo-Brownian motion into work by means of a granular gas,"Classical thought experiment brought to life in granular gas", Foundation for Fundamental Research on Matter, Utrecht, 18 June 2010. Retrieved on 2010-06-24. which is a conglomeration of solid particles vibrated with such vigour that the system assumes a gas-like state. The constructed engine consisted of four vanes which were allowed to rotate freely in a vibrofluidized granular gas.

John Lilburne who was bitterly hostile to all the Vanes because Sir Henry had been one of his judges, accused him of causing the loss of Durham by negligence and treachery, but the charge met with no belief from parliament. Vane was a member of the Committee of Both Kingdoms from its first establishment (7 February 1644). In April 1645 he was employed as one of its representatives with the Scottish auxiliary army. At the Treaty of Uxbridge Parliament asked the king to make Vane a baron, his favour with the parliament is shown by the ordinances for the payment of his losses during the war.

In 1551, Taqi ad-Din Muhammad ibn Ma'ruf in Ottoman Egypt invented a steam jack, driven by a steam turbine, describing a method for rotating a spit by means of a jet of steam playing on rotary vanes around the periphery of a wheel.Taqi al-Din and the First Steam Turbine, 1551 A.D. , web page, accessed on line October 23, 2009; this web page refers to Ahmad Y Hassan (1976), Taqi al-Din and Arabic Mechanical Engineering, pp. 34–5, Institute for the History of Arabic Science, University of Aleppo. It was the first practical steam jet device. A similar device was later described by John Wilkins in 1648.

The final CSX was 1989's CSX-VNT. This would also be the final Shelby Dodge, and marked two notable technological advances: the introduction of a Garrett variable-nozzle turbo (VNT), which was the first application of variable turbine technology in a production car, and the application of composite wheels designed by Shelby and produced by Motor Wheel Corporation, known as "Fiberrides", which were lighter than contemporary aluminum wheels. The first 1989 CSX VNT, Carroll Shelby's own car 1989 Shelby CSX VNT The engine was Chrysler's new intercooled Turbo IV equipped with a Getrag A555 5-speed transmission. The variable geometry turbo vanes were computer controlled and needed no wastegate.

Air entered the engine through a conventional air intake, flow splitting after the initial guide vanes to the compressor inside and the ducted fan outside, with a by-pass ratio of approximately 2.45:1. The compressor consisted of seventeen stages of blading, eight carried on the inner drum, rotating at full engine speed, and nine on the outer drum which rotated in the opposite direction at 0.5:1 engine speed. Although extremely complicated mechanically, a compressor efficiency of 80% was expected with a very credible pressure ratio of 8:1. For comparison, typical engines of the era offered pressure ratios on the order of 3.5:1.

New tail surfaces were tested in the Zeppelin Aircraft Works subsonic tunnel and the supersonic tunnel in Aachen. The internal vanes were now made of Graphite instead of molybdenum. Uncontrolled A-5's were launched from Griefswalder Oie in the autumn of 1938. Models 5 feet long and 8 inches in diameter were dropped from He-111s starting in September 1938, testing supersonic speeds in the absence of a supersonic wind tunnel. Hellmuth Walter also made models of the A-5 that were 5 feet long and 8 inches in diameter. They included a hydrogen peroxide motor, with potassium permanganate as a catalyst, and test launched in March 1939.

In 2004, the entire DT family of engines was updated to meet 2004 emissions standards set out by the United States Environmental Protection Agency. Changes to the engines included a new turbocharger (called EVRT, for "Electronic Variable Response Turbocharger") with movable turbo vanes to improve boost and reduce lag, a new, electronically controlled hydraulic unit fuel injection system, cooled Exhaust Gas Recirculation to reduce emissions, and new four-valve cylinder heads. In 2007, the DT engines were updated once again to comply with stricter 2007 emissions standards. The DT 466, DT 570, and HT 570 engines will be renamed MaxxForce DT, MaxxForce 9, and MaxxForce 10, respectively.

It also powered the Antonov An-22 Antei (with NK-12MA), the world's largest aircraft at the time, and several types of amphibious assault craft, such as the A-90 Orlyonok "Ekranoplan". The engine has a 14-stage axial-flow compressor, producing pressure ratios between 9:1 and 13:1 depending on altitude, with variable inlet guide vanes and blow-off valves for engine operability. The combustion system used is a cannular-type: each flame tube is centrally mounted on a downstream injector that ends in an annular secondary region. The contra- rotating propellers and compressor are driven by the five-stage axial turbine.

The composition of most ash is such that its melting temperature is within the operating temperature (>1000 °C) of modern large jet engines. The degree of impact depends upon the concentration of ash in the plume, the length of time the aircraft spends within the plume and the actions taken by the pilots. Critically, melting of ash, particularly volcanic glass, can result in accumulation of resolidified ash on turbine nozzle guide vanes, resulting in compressor stall and complete loss of engine thrust. The standard procedure of the engine control system when it detects a possible stall is to increase power which would exacerbate the problem.

Uriah Boyden, about 1845 Boyden turbine Uriah Atherton Boyden (February 17, 1804 - October 17, 1879) was a civil and mechanical engineer and inventor from Foxborough, Massachusetts best known for the development of a water turbine, that later became known as the Boyden Turbine around 1844, while working for the Appleton Company in Lowell, Massachusetts. Boyden improved upon a turbine developed by French engineer Fourneyron by adding a conical approach passage for the incoming water—submerged diffusers, guide vanes and a diverting exit passage.ASME biography Uriah A. Boyden Uriah was also the younger brother of Seth Boyden, also a notable inventor who perfected a process for making patent leather, among other developments.

The original prototype of Salter's duck was made of "a string of floating vanes of rudimentary duck cross-sections linked through a central spine". The string itself had 12 ducks attached to it that were "50 cm wide mounted on a spine 27 cm in diameter and 6 m long." It was made at Coventry University, with materials from Ready Made Concrete and Insituform. The final design worked by having 20 to 30 ducks connected together by the jointed spine, with each duck moving with the waves that hit it and transferring the energy of the impact to "six to ten pumps" for each duck.

Seven- segment displays may use a liquid crystal display (LCD), a light-emitting diode (LED) for each segment, an electrochromic display, or other light- generating or controlling techniques such as cold cathode gas discharge (Panaplex), vacuum fluorescent (VFD), incandescent filaments (Numitron), and others. For gasoline price totems and other large signs, vane displays made up of electromagnetically flipped light-reflecting segments (or "vanes") are still commonly used. An alternative to the 7-segment display in the 1950s through the 1970s was the cold-cathode, neon-lamp-like nixie tube. Starting in 1970, RCA sold a display device known as the ' that used incandescent filaments arranged into a seven-segment display.

This would cause the image to once again begin trailing the target, requiring another correction, and so on. If the launch was too far behind the target, the operator eventually ran out of control power as the missile approached, leading to a circular error probable (CEP) of , too far to be useful. After considering a number of possibilities to solve this, including a proportional navigation system, they settled on an extremely simple solution. Small wind vanes on the nose of the missile were used to rotate the camera so it was always pointed in the direction of the flight path, not the missile body.

The feather studied was most probably a dorsal covert, which would have partly covered the primary feathers on the wings. The study does not mean that Archaeopteryx was entirely black, but suggests that it had some black colouration which included the coverts. Carney pointed out that this is consistent with what we know of modern flight characteristics, in that black melanosomes have structural properties that strengthen feathers for flight. In a 2013 study published in the Journal of Analytical Atomic Spectrometry, new analyses of Archaeopteryxs feathers revealed that the animal may have had complex light- and dark- coloured plumage, with heavier pigmentation in the distal tips and outer vanes.

The centre span of the bridge is long and the two symmetric end sections each measure . The bridge footway is wide and stands above the average water level at the centre and above at each end. The towers, each of which stands high, when first built were cased externally with ornamental cast-iron work and the bases were panelled and decorated with the arms and supporters of Lord Burton, together with his motto – ‘Basis Virtutum Constantia’ (The basis of virtue is constancy). The towers were surmounted with lions rampant each of which carried a wrought iron staff with gilded copper vanes and Lord Burton's monogram.

In March 2011 the FAA issued an Airworthiness Directive restricting operation of the entire fleet of EA500s to from its previous limit of and before that . The AD was required because a build-up of hard carbon deposits on the engine static vanes caused at least six reported engine surge incidents, requiring pilots to decrease power on the affected engine. The FAA was concerned that this problem "could result in flight and landing under single-engine conditions" or if it affected both engines, a double engine failure. This action is considered an interim solution while the engine certification authority, Transport Canada and Pratt & Whitney Canada devise a more permanent solution.

None of these contour feathers could be definitely identified as being pennaceous, with closed vanes. Life restoration of Caihong juji (Without crest) The fossilized feathers of Caihong possessed nanostructures which were analyzed and interpreted as melanosomes, showing similarity to organelles that produce a black iridescent color in extant birds. Other feathers found on the head, chest, and the base of the tail preserve flattened sheets of platelet- like melanosomes very similar in shape to those which create brightly colored iridescent hues in the feathers of modern hummingbirds. However, these structures are seemingly solid and lack air bubbles, and thus are internally more akin to the melanosomes in trumpeters than hummingbirds.

For the final race of the season, the 2008 Brazilian Grand Prix, Williams again tweaked the profile of the main and middle elements of the front wing. Small curved steps were added to the outer extremities of these elements to increase the speed of airflow through the wing tip, increasing downforce without increasing drag. Small sidepod winglets were significantly altered prior to the 2008 French Grand Prix, providing twin turning vanes to better control airflow over the rear of the car. At the Canadian Grand Prix tweaks were also made to the flip-up flaps in front of the rear wheels, to reduce drag.

Police became involved with the case after the incidents at Denyer's block of units, where the first slasher break-in occurred, and at Vanes' unit in February 1993. The murder of Stevens was the first incident to attract a large investigation, as did the disappearance of Fream, when a search was organised and scuba divers examined the Kananook Creek. No external forensic evidence was found at the Stevens scene, and no witnesses came forward. With Fream, again, no foreign forensic evidence was found at the scene due to poor weather, but witnesses later recalled her car, a gray Nissan Pulsar, had been seen driving erratically and flashing its high-beam lights.

Possibly the same device was referred to as "umbrella lamp" and mentioned as "a variety of zoetrope" which "may well have originated in China" by historian of Chinese technology Joseph Needham. It had pictures painted on thin panes of paper or mica on the sides of a light cylindrical canopy bearing vanes at the top. When placed over a lamp it would give an impression of movement of animals or men. Needham mentions several other descriptions of figures moving after the lighting of a candle or lamp, but some of these have a semi-fabulous context or can be compared to heat operated carousel toys.

Communications consisted of a 3-watt transmitter capable of continuous telemetry operation, the large high gain directional dish antenna, a cylindrical omnidirectional antenna at the top of the instrument mast, and two command antennas, one on the end of either solar panel, which received instructions for midcourse maneuvers and other functions. Propulsion for midcourse maneuvers was supplied by a monopropellant (anhydrous hydrazine) 225 N retro-rocket. The hydrazine was ignited using nitrogen tetroxide and aluminum oxide pellets, and thrust direction was controlled by four jet vanes situated below the thrust chamber. Attitude control with a 1 degree pointing error was maintained by a system of nitrogen gas jets.

Recognised that that its name needed to be easily recognised internationally, the company changed its name to the Volvo Aero Corporation during the early 1990s. By the late 1990s, Volvo Aero's component range included fan cases, fan-compressor structures, compressor rotors, shafts, combustor structures, vanes, low-pressure turbine (LPT) cases, turbine structures, rocket nozzles, combustion chambers, and rocket engine turbines for both civilian and military purposes. By 2003, the firm's workforce comprised 3,600 employees, it also recorded total sales of 0.9 billion euros during that year. Presently, Volvo Aero is a partner in more than ten commercial engine programmes and components produced by the company are installed in more than 90% of all large commercial aircraft engines sold.

The opposite facade includes vestiges of stairs, while the right-facing lateral wall (facing the south) is comparable to the northern facade, with the addition of the sacristy, that includes two rectangular windows flanked by two elliptical oculi. On the annex are three cracks and lintel doorway. The rear of the church includes three covered spaces, corresponding to the church's annexes, which are the largest spaces of the complex, with the rear facade broken by a small niche, surmounted by triangular pediment, while the presbytery gable can be seen from the grounds. Between the presbytery and sacristy is the belltower with Roman arch, decorated with cornices, pinnacles and small belfrey flanked by vanes and cornice, with spire and weathervane.

Giving the molecule this extra boost effectively means that a minute pressure is exerted on the vane. The imbalance of this effect between the warmer black side and the cooler silver side means the net pressure on the vane is equivalent to a push on the black side and as a result the vanes spin round with the black side trailing. The problem with this idea is that while the faster moving molecules produce more force, they also do a better job of stopping other molecules from reaching the vane, so the net force on the vane should be the same. The greater temperature causes a decrease in local density which results in the same force on both sides.

By designing the fan blades with proper hub-to-tip ratio and analyzing performance on the number of blades so that the flow doesn't separate on the blade surface these effects can be reduced. Some of the methods to overcome these effects are re-circulation of excess air through the fan, axial fans are high specific speed devices operating them at high efficiency and to minimize the effects they have to be operated at low speeds. For controlling and directing the flow use of guide vanes is suggested. Turbulent flows at the inlet and outlet of the fans cause stalling so the flow should be made laminar by the introduction of a stator to prevent the effect.

88 The first engine start was attempted on 27 October 1944. A number of snags delayed the run until nearly midnight, when with almost the entire day and night shift staff watching, an attempt was made to start the engine, without the inlet vanes, which had not yet been fitted. To everyone's dismay the engine refused to light - positioning the igniter was a trial-and-error affair at the time. On the next attempt, Denis Drew unscrewed the igniter and as the starter motor ran the engine up to speed, lit the engine with an oxy-acetylene torch. The engine was run up to 4,000 lbf and more, and a cheer went up around the assembled personnel.

Modern instruments used to measure wind speed and direction are called anemometers and wind vanes, respectively. These types of instruments are used by the wind energy industry, both for wind resource assessment and turbine control. When a high measurement frequency is needed (such as in research applications), wind can be measured by the propagation speed of ultrasound signals or by the effect of ventilation on the resistance of a heated wire. Another type of anemometer uses pitot tubes that take advantage of the pressure differential between an inner tube and an outer tube that is exposed to the wind to determine the dynamic pressure, which is then used to compute the wind speed.

They are topped by tapering finials with weather vanes. Above the Perpendicular Gothic west doorway, which has "nicely carved" and moulded spandrels and a four-centred arch, are John Bolney's coat of arms (whose heraldic description is Or a crescent with two molets gules in the chief) and the inscription which was added in 1538 upon completion of the tower. A peal of eight bells is set in a bell-chamber near the top of the tower, lit by four two-light, flat- arched windows. The church is well known for this large complement of bells and the regular bellringing that takes place, and the ancient pub opposite the church is named The Eight Bells in recognition of this.

Several different types of pump impellers Flexible impeller of cooling system pump of an outboard engine. (Coin for comparison, diameter 16.25 mm.) An impeller is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped. The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing. An impeller is usually a short cylinder with an open inlet (called an eye) to accept incoming fluid, vanes to push the fluid radially, and a splined, keyed, or threaded bore to accept a drive shaft.

For 1949, minor modifications to the brake drums, switching from vanes to slits for cooling, along with small changes to the cockpit control layout and a repositioned oil header-tank resulted in a car sometimes referred to as the 4CLT/49. It was never known as such by the factory. The Ascari/Villoresi/Parnell trio, joined by Juan Manuel Fangio and Toulo de Graffenried, took up where they had left off the previous season, winning nine of the first fifteen races of 1949, including de Graffenried's victory in the British Grand Prix. However, the second half of the season only saw three further wins, as increasingly competitive Ferrari and Talbot cars squeezed out the Maseratis in most major races.

VGTs tend to be much more common on diesel engines, as lower exhaust temperatures mean they are less prone to failure. Early gasoline-engine VGTs required significant pre-charge cooling to extend the turbocharger life to reasonable levels, but advances in technology have improved their resistance to high-temperature gasoline exhaust, and they have started to appear increasingly in gasoline- engined cars. Typically, VGTs are only found in OEM applications due to the level of coordination required to keep the vanes in the most optimal position for whatever state the engine is in. However, there are aftermarket VGT control units available, and some high-end aftermarket engine management systems can control VGTs as well.

A low- bypass-ratio (BPR) afterburning turbofan engine featuring a six-stage core high-pressure (HP) compressor with variable inlet guide vanes (IGVs), a three- stage low-pressure (LP) compressor with transonic blading, an annular combustion chamber, and cooled single-stage HP and LP turbines. The development model is fitted with an advanced convergent-divergent ("con-di") variable nozzle, but the GTRE hopes to fit production Tejas aircraft with an axisymmetric, multi-axis thrust-vectoring nozzle to further enhance the LCA's agility. The core Turbojet engine of the Kaveri is the Kabini. The general arrangement of the Kaveri is very similar to other contemporary combat engines, such as the Eurojet EJ200, General Electric F414 and Snecma M88.

This instrument is interesting in that the arc is 120° but is only graduated as a 90° arc. As such, the angular spacing of a degree on the arc is slightly greater than one degree. Examples of the instrument can be found with a 0° to 90° graduation or with two mirrored 0° to 45° segments centred on the midpoint of the arc. The instrument has three vanes, a horizon vane (A in Figure 8) which has an opening in it to observe the horizon, a shadow vane (B) to cast a shadow on the horizon vane and a sighting vane (C) that the navigator uses to view the horizon and shadow at the horizon vane.

Hydro tailrace fishing is a more modern form of fishing the turbulent waters below reservoirs. The term hydro generation refers to the massive generators within a dam structure that are propelled by the force of gravity pushed by the vessel of water through an impeller which rotates the rotor causing lines of magnetic flux thus creating electric current which can then be transmitted as electricity. When vanes or valves are opened the water immediately flows from the above reservoir, causing turbulent water below the dam structure. Generation once started can last for a few minutes and up to months at times if all mechanical conditions and market demand is required from the governing utility or municipality.

Artist's concept of X-43A with scramjet attached to the underside A ramjet is a form of jet engine that contains no major moving parts and can be particularly useful in applications requiring a small and simple engine for high-speed use, such as with missiles. Ramjets require forward motion before they can generate thrust and so are often used in conjunction with other forms of propulsion, or with an external means of achieving sufficient speed. The Lockheed D-21 was a Mach 3+ ramjet-powered reconnaissance drone that was launched from a parent aircraft. A ramjet uses the vehicle's forward motion to force air through the engine without resorting to turbines or vanes.

The first settlement was established in 1901 when H Blake founded the first timber mill known as Blake's Mill; later a larger mill was constructed and completed in 1913 by the Victorian Powell Wood Processing Company to harvest hardwood mountain ash in the Little Yarra Valley to fill its new government contracts. The logs were transported from the forests to the sawmills by tramway and from there to the railheads at Yarra Junction and Warburton. With renowned axemen like Shane Corr, who opened up the vanes of timber with no more than an axe and a team of bullocks to for fill his government contracts. The Post Office opened around 1904 as Blake's and was renamed Powelltown in 1912.

Crew working on the diffuser and contraction vanes, 1996 Aerial view of the Wind Tunnel with construction going on in the mid-1950s The American West Coast aircraft industry quickly capitalized on the Ames Unitary Plan Wind Tunnel Complex. The famed Boeing fleet of commercial transports and the Douglas DC-8, DC-9, and DC-10 were all tested here; as well as military aircraft such as the F-111 fighter, the C-5A Galaxy transport and the B-1 Lancer bomber. In addition to aircraft, in the 1960s and 1970s all NASA manned space vehicles including the Space Shuttle and SLS have been tested in the Ames Unitary Plan Wind tunnel complex.

At the Lister Institute of Preventive Medicine, liquid air has been brought into use as an agent in biological research. An inquiry into the intracellular constituents of the typhoid bacillus, initiated under the direction of Dr Allan Macfadyen, necessitated the separation of the cell- plasma of the organism. The method at first adopted for the disintegration of the bacteria was to mix them with silver-sand and churn the whole up in a closed vessel in which a series of horizontal vanes revolved at a high speed. But certain disadvantages attached to this procedure, and accordingly some means was sought to do away with the sand and triturate the bacilli per se.

The main characteristic of a torque converter is its ability to multiply torque when the output rotational speed is so low that it allows the fluid coming off the curved vanes of the turbine to be deflected off the stator while it is locked against its one-way clutch, thus providing the equivalent of a reduction gear. This is a feature beyond that of the simple fluid coupling, which can match rotational speed but does not multiply torque, thus reduces power. Some of these devices are also equipped with a "lockup" mechanism which rigidly binds the engine to the transmission when their speeds are nearly equal, to avoid slippage and a resulting loss of efficiency.

The engine has replaceable steel blades and vanes, which are more reliable but heavier than titanium. The AE 2100 engine and gearbox are rated at , but was derated to for the Saab 2000, Lockheed Martin C-130J Super Hercules, and IPTN N-250, respectively. The engine uses six-bladed, all-composite blade Dowty propellers, including the model R381 on the Saab 2000, R414 on the ShinMaywa US-2, R384 on the IPTN N-250, and R391 on the C-130J military transport and the LM-100J civil- certified version of the C-130J. The gearbox has a reduction ratio of about 14 and a mean time before unscheduled removal (MTBUR) of over 35,000 hours.

The same four figures, cast in bronze, look out over the four quarters of the Earth from the base of the steeple. The two flanking weather vanes show a certain symbolic debt to William Blake's Jerusalem depicting, as they do, a fiery chariot and a sheaf of arrows (presumably of desire), while the main steeple is clearly surmounted by a spear. The stained glass windows, designed by noted children's book illustrator Walter Crane, and made by J. S. Sparrow, betray the unconventional nature of the sect as they illustrate the 'true station of womankind'. The church was abandoned after 1956, used by a splinter group, and now is used by the Georgian Orthodox Church.

A jackdaw standing on the vanes of a cathedral tower is said to foretell rain. The 12th-century historian William of Malmesbury records the story of a woman who, upon hearing a jackdaw chattering "more loudly than usual," grew pale and became fearful of suffering a "dreadful calamity", and that "while yet speaking, the messenger of her misfortunes arrived". Czech superstition formerly held that if jackdaws are seen quarreling, war will follow, and that jackdaws will not build nests at Sázava after being banished by Saint Procopius. The jackdaw was considered sacred in Welsh folklore as it nested in church steeples – it was shunned by the Devil because of its choice of residence.

At take- off with the weight of the four solid boosters, the centre of gravity would be brought back to 65%, but after releasing these rockets it would move forwards to 22%. The free flight by Zübert on 14 February had showed unequivocally that the little Natter had excellent flying characteristics as a glider. The centre of gravity problem was solved initially by the addition of one-metre-square auxiliary tailfins that were released simultaneously with the jettisoning of the boosters. The Krokus aircraft had vanes that would direct the Walter rocket exhaust gases so as to assist vehicle stabilisation at low speed similar to those used in the V-2 rocket.

The walls of these two towers are around thick at the base, thinning to at the top. The Well Tower at in diameter is slightly narrower than the Keep or Kitchen Tower, with a well in its lowest chamber sunk into the ground. The Well Tower lacks the spurs of the other two towers and has a flat rather than curved back, facing onto the courtyard, similar to some of the towers built at Caerphilly by the de Clares. The conical roofs of the Well Tower (left) and Keep (right), topped by elaborate weather vanes and chimneys The towers contribute to what the architectural writer Charles Handley-Read considered the castle's "sculptural and dramatic exterior".

The AS-20 had four steeply swept-back fins, cruciform in cross-section around the midsection of its body. It used a dual-thrust solid rocket motor, which exhausted through two large nozzles during the boost stage, and a single center line nozzle during the sustain stage. The AS-20 uses a simple MCLOS guidance with the pilot aligning the flares on the missile's rear with the target and controlling the missile in flight after launch with a small joystick sending steering commands to the missile via a radio link. The steering commands steer the missile back to the line-of-sight by thrust vectoring by the movement of one of four metal vanes around the center sustainer nozzle.

The pointing direction was determined during data processing, using the inertial guidance system of the SIV-B stage combined with information from two visible star sensors which formed part of the experiment. Galactic X-ray sources were observed with the S150 experiment. The experiment was designed to detect 4.0-10.0 nm photons. It consisted of a single large (~1500 cm2) proportional counter, electrically divided by fine wire ground planes into separate signal-collecting areas and looking through collimator vanes. The collimators defined 3 intersecting fields of view (~2 × 20°) on the sky, which allowed source positions to be determined to ~ 30'. The front window of the instrument consisted of a 2 µm thick plastic sheet.

The stator element of the torque converter has two blade positions, controlled by the driver via the accelerator pedal to offer a 'passing gear' and extra response at any speed from heavy throttle application. In normal driving the stator blades are arranged at 'cruise' angle, with improved efficiency and response at light throttle. Opening the throttle changes the angle of the stator vanes hydraulically to 'performance angle', which permits the converter to achieve stall about 1000 rpm higher than in 'cruise'. In this situation oil is redirected to strike the next- lowest drive turbine, which effectively lowers the drive ratio, and allows engine speed to flare to a speed where output is greatest.

The AVGP (Armoured Vehicle General Purpose), later known as the LAV I (Light Armoured Vehicle I), is a series of three armoured fighting vehicles ordered by the Canadian military in the 1970s. The vehicles, named Grizzly, Cougar and Husky respectively, were based on the six-wheeled version of the Swiss MOWAG Piranha I, and became the first generation Light Armoured Vehicle produced by General Dynamics Land Systems - Canada. The Canadian Army retired all AVGP variants beginning in 2005; however, a number of the retired vehicles were transferred to other military's and police forces, where they continue to serve. The AVGP had propellers and trim vanes for amphibious use, like the eight-wheeled Bison, which was the vehicle family's immediate successor.

Alexis Badmaieff, Head of Acoustic Engineering at Altec at the time, changed the horn design from a true multicellular type to what was really a sectoral horn with "fins" inside the bell flare. The fins did not go all the way back to the opening of the throat of the horn, as did the previous design. A young Paul S. Veneklasen, who was working in the acoustic research department at Altec at the time, objected to the change, claiming that it was done to save money, not because it was an acoustical improvement. His protestations went unheeded and the sectoral horn with the "fins", or as some called them, "vanes", remained in use in the 604, starting with the "C" version and continuing through the "G".

The officer, however, claimed it his duty to bless and propagate Hashim's memory on account of his generosity of providing financial support and a secure haven in times of hardship. Mansur was moved by his response and replied "Would that I had men like him in my army!" and ordered the officer to be given a sum payable at the treasury. In a narration by Aban ibn abi-Ayyash, Al Mansur was sitting in an audience hall above the Khurasan Gate looking out over the Tigris when an arrow was shot from an unknown location at his feet. Decorated on the vanes were verses prompting him to reflect on his reign as Caliph and to remember his appointment with Judgement Day.

The acronematic posterior flagellum is used in feeding and to attach to substrate, while the anterior flagellum beats less rapidly and in a slow sweeping motion. Further studies by Simpson and Patterson (1999) go into greater detail about the flagella and describe the flagellar apparatus as having a third, barren basal body. Supporting the dorsal side of the cell is a microtubular fan with a microtubular root at the anterior end. On the ventral side, microtubules extending from different flagellar roots support the ventral groove. The anterior flagellum has a ‘9+2’ axoneme. Simpson and Patterson described that in addition to the ‘9+2’ axoneme, the posterior flagellum also has “three radiating lamellae of electron-dense material which form the central components of vanes”.

Some of the earliest German seekers used a linear-scan solution, where vertical and horizontal slits were moved back and forth in front of the detector, or in the case of Madrid, two metal vanes were tilted to block off more or less of the signal. By comparing the time the flash was received to the location of the scanner at that time, the vertical and horizontal angle-off can be determined. However, these seekers also have the major disadvantage that their FOV is determined by the physical size of the slit (or opaque bar). If this is set too small the image from the target is too small to create a useful signal, while setting it too large makes it inaccurate.

The Airlander 10 possesses a sizeable flight deck with four large floor-to-ceiling windows, providing a high level of external visibility. While the airship had originally been envisioned to be unmanned, HAV adopted an optionally piloted approach as a result of customer interest in such operations. In 2015, positions for a single pilot and an observer had been installed in the Airlander 10; HAV intend to adopt a twin- pilot configuration along with a greater prevalence of glass cockpit-style controls and instrumentation in the future. The airship is controlled by a side-stick mounted on the right-hand side, somewhat resembling that of a rotorcraft; there are no rudder pedals, the side-stick being automatically slaved to the vanes instead.

Front view The 1.9 m (75 in) fan has 18 titanium alloy blades, providing an 8.5:1 bypass ratio significantly improved from previous Russian engines, but slightly below the CFM LEAP's 10:1 or the Pratt & Whitney PW1000G's 12:1 for the MC-21 from 2017. The 3D aerodynamics shaped first high-pressure turbine stage has advanced cooling channels. Twenty new materials were developed for the powerplant, including monocrystalline alloys for vanes, and high-strength nickel and titanium alloys for shafts and disks. Separated rear exhaust, ILA Berlin Air Show 2012 Developed from the PS-12 (an uprated PS-90A), the 122-153 kN (27,500-34,500 lbf) thrust powerplant is designed by Aviadvigatel and manufactured by the Perm Engine Company.

The original Atar 101 featured a seven-stage axial compressor using aluminum alloy blades attached to an aluminum rotor. The front bearing was held in place by four vanes, with the "left" one as seen from the front containing a power takeoff shaft. One unique feature of the Atar designs was the separate Atar 5000 accessories section, which could be mounted in front of the engine, driven by an extension shaft. The combustion area consisted of twenty steel flame cans arranged in a "canular" layout, exiting into the single-stage turbine. Early models were 2.85 m long, 0.9 m in diameter, and weighed 850 kg, while The C models and on were 3.68 m lone including the long extension, 0.89 m in diameter, and weighed 940 kg.

Often compared to Ferrari, whose car featured straight-line speed, low drag, and high-speed prowess, its victories were often attributed to the ease in working the new Pirelli tire concept with its overwhelming downforce. The Mercedes car received its first major upgrade in Spain, where it followed up a front wing update in China with a redesign of the bargeboards "boomerang". A major weakness was first observed and uncovered in Austria, when team members remarked on the inability of the car's deliberately tight cooling to operate optimally under high-altitude and hot temperature conditions. It received another major upgrade in Germany, where the team revised the car's rear-facing cooling outlets, sidepod vanes, bargeboards, and a new rear wing endplate design, (among other changes).

Sauber brought a "heavily- updated car" to the Grand Prix, featuring a shorter nose and revised front and rear wings as well as a new engine cover and brake ducts. Toro Rosso also came to Singapore with new parts, bringing a revised front wing. Red Bull introduced a new component as well: Daniil Kvyat's car was equipped with new turning vanes installed to improve the airflow under the car and therefore create more downforce. The feature would be run by both cars at the following Japanese Grand Prix. Further updates included changes to the diffuser, rear wing, brake ducts and bodywork of the Force India VJM08B and modifications to the floor in front of the rear wheels of the Ferrari SF15-T.

Borazon has a number of uses , such as: cutting tools, dies, punches, shears, knives, saw blades, bearing rings, needles, rollers, spacers, balls, pump, compressor parts, engine & drive train components (e.g. camshafts, crankshafts, gears, valve stems, drive shafts, CV joints, piston pins, fuel injectors, turbochargers, and aerospace and land-based gas turbine parts such as vanes, blades, nozzles, and seals), surgical knives, blades, scissors, honing, superfinishing, cylinder liners, connecting rods, grinding of steel and paper mill rolls, and gears. Prior to the production of Borazon, diamond was the preferred abrasive used for grinding very hard superalloys but it could not be used effectively on steels because carbon tends to dissolve in iron at high temperatures. Aluminium oxide was the conventional abrasive used on hardened steel tools.

Compressed air is the most common power source for impact wrenches, providing a low-cost design with the best power-to-weight ratio. A normal vane motor is almost always used, usually with four to seven vanes, and various lubrication systems, the most common of which uses oiled air, while others may include special oil passages routed to the parts that need it and a separate, sealed oil system for the hammer assembly. Most impact wrenches drive the hammer directly from the motor, giving it fast action when the fastener requires only low torque. Other designs use a gear reduction system before the hammer mechanism, most often a single-stage planetary gearset usually with a heavier hammer, delivering a more constant speed and higher "spin" torque.

This environmentally friendly and recyclable soft grit abrasive is well suited for air blasting, deburring, descaling, and polishing operations because of its elasticity and resilience. Uses include cleaning automobile and jet engines, electronic circuit boards, and paint and graffiti removal. For example: In the early days of jet transportation, crushed walnut shells were used to scour the compressor airfoils clean, but when engines with air cooled vanes and blades in the turbine started being manufactured, this practice was stopped because the crushed shells tended to plug up the cooling passages to the turbine, resulting in turbine failures due to overheating. ;Oil well drilling : The shell is used widely in oil well drilling for lost circulation material in making and maintaining seals in fracture zones and unconsolidated formations.

With Coach Myers still at the helm the Banshees approached the season with confidence that they could improve upon the previous year, however the early season loss of American quarterback Yenerall and dominant nose tackle Marcus Campbell to the nearby Premiership giants Bristol Aztecs was a major setback. The Banshees did manage an impressive 34-0 victory over the Cornish Sharks early on but that was to be the only highlight of the season as after that the loss of key offensive linemen Iain Vanes (career ending knee injury) and Karl Friston (joined Bristol Aztecs) decimated the offence even further. Despite creditable performances away to Watford Cheetahs and Milton Keynes Pathfinders the Banshees ended the season with a 1-9 (W-L) record.

Further proposed developments included the CL-958 with larger wings, the CL-981 with retractable canard wings behind the cockpit, and the CL-984 optimised for low-level strike missions. An RF-104G was modified and flew in December 1966 as the prototype CL-901 "Super Starfighter". Externally, the new type had slightly larger air intakes and steel inlet guide vanes that allowed an increase in operating temperature from , enabling a maximum speed of Mach 2.2. During the first five years in Italian service, 23 F-104G aircraft were lost; as only 80 to 90 F-104s (of 149 acquired) were operational at best, it was decided to purchase a new interceptor and fighter- bomber to reinforce front-line units.

Prior to the car's launch, McLaren announced plans for an extensive aerodynamic update to be introduced for the opening round of the championship in Australia. However, the team later admitted that their reliability issues during pre-season testing had forced them to delay the introduction of planned upgrades until the second round in Bahrain. The updates featured revisions to the front wing that were aimed at stabilising the airflow over the car and a new design for the bargeboards and turning vanes that was modelled on a concept pioneered by Red Bull Racing and Ferrari in . Following the Chinese Grand Prix, team principal Eric Boullier stated that the team's planned schedule of updates meant that the "real" MCL33 would not appear until the Spanish Grand Prix.

Engineers determined that the high-pressure turbine of engine #4, that had been installed during the last work shop visit in January 2008, was inefficient due to too large a blade tip clearance, the reduced chord and wear of leading edges of fan blades resulting in a loss of engine power estimated at 5.8%. The high altitude impaired stability and operatibility of the engine. Engine #1 then suffered a failure of the low-pressure turbine, which resulted in ejection of engine parts through the engine exhaust. The failure originated in the third stage of the LPT, engineers believe the failure started with the loss of a number of guide vanes or the loss of a large piece of outside air seal due to thermal damage.

An even larger booster took the missile to hypersonic speeds while still in the lower atmosphere, so the missile fuselage had to be covered over completely with a phenolic ablative heat shield to protect the airframe from melting. Another change was to combine the aerodynamic controls used for control in the lower atmosphere with the thrust vectoring engines, using a single set of movable jet vanes for both roles. The new DM-15B Nike Zeus B (the earlier model retroactively becoming the A) received a go ahead for development on 16 January 1958, the same date the Air Force was officially told to stop all work on a Wizard missile. On 22 January 1958, the National Security Council gave Zeus S-Priority, the highest national priority.

The disassembled weapon was usually transported on horsedrawn carts but the Canadian Automobile Machine Gun Brigade (the Canadian Independent Force or "Brutinel's Brigade") is known to have successfully used the mortar both mounted on motor trucks and dismounted in the closing months of the war.Michael Holden, University of New Brunswick, "Training, Multi-National Formations, and Tactical Efficiency: The Canadian Motor Machine Gun Brigades in 1918"Danish Military History Society, "The Canadian Motor Machine Gun Brigade, Part 1" The 52-pound cast-iron fin-stabilised high explosive bomb carried the percussion primer at the base in the intersection of the four vanes (fins), consisting of a specially loaded blank .303 rifle cartridge. The basic propellant charges were contained in four small white cambric bags each containing 1 oz of guncotton yarn.

Maxwell died that year and the Royal Society refused to publish Reynolds's critique of Maxwell's rebuttal to Reynolds's unpublished paper, as it was felt that this would be an inappropriate argument when one of the people involved had already died. Reynolds found that if a porous plate is kept hotter on one side than the other, the interactions between gas molecules and the plates are such that gas will flow through from the hotter to the cooler side. The vanes of a typical Crookes radiometer are not porous, but the space past their edges behaves like the pores in Reynolds's plate. On average, the gas molecules move from the hot side toward the cold side whenever the pressure ratio is less than the square root of the (absolute) temperature ratio.

Most of the yeserias of arabesques, which carpeted the walls of these stays with decorative panels plastered with plaster, as well as an alabaster base of two and a half meters high and the white marble floors of the original palace, have been lost. The remains that have been preserved, both in museums and the few that are in this royal hall, nevertheless allow to reconstruct the appearance of this polychrome decoration, which, in its day, should have been splendid. Ceilings, wood carvings, reproduced the sky, and the whole room was an image of the cosmos, clothed with symbols of the power exercised over the celestial universe by the monarch of Saragossa, who thus appeared as heir to the caliphs. The access to the Golden Hall is made through a canvas with three vanes.

Barber's turbine was used to burn gas obtained from wood, coal, oil, or other substances, heated in a retort or producer, from where the gases were conveyed into a receiver and cooled. Air and gas were then to be compressed in different cylinders and pumped into an "exploder" (combustion chamber) where they were ignited, the mixture of hot gas then being played against the vanes of a paddle wheel. Water was to be injected into the explosive mixture to cool the mouth of the chamber and, by producing steam, to increase the volume of the charge. Barber's concept was sound, but given the technology of that day, it was not possible for the device to create sufficient power to both compress the air and the gas and produce useful work.

The Juno I consisted of a Jupiter-C first stage, based on the Redstone missile; with three additional solid fuel stages based on the Sergeant missile to provide the added impulse to achieve orbit. The fourth stage was mounted on top of the "tub" of the third stage, and fired after third-stage burnout to boost the payload and fourth stage to an orbital velocity of . The tub along with the fourth stage were set spinning while the rocket was on the launch pad to provide gyroscopic force in lieu of a guidance system that would have required vanes, gimbals, or vernier motors. This multi-stage system, designed by Wernher von Braun in 1956 for his proposed Project Orbiter, obviated the need for a guidance system in the upper stages.

The LPB process includes a unique and patented way of analyzing, designing, and testing metallic components in order to develop the unique metal treatment necessary to improve performance and reduce metal fatigue, SCC, and corrosion fatigue failures. Lambda modifies the process and tooling for each component to provide the best results possible and to ensure that the apparatus reaches every inch on the component. With this practice of customization along with the closed-loop process control system, LPB has been shown to produce a maximum compression of 12mm, although the average is around 1-7+mm. LPB has even been shown to have the ability to produce through-thickness compression in blades and vanes, greatly increasing their damage tolerance over 10-fold, effectively mitigating most FOD and reducing inspection requirements.

The Armoured Vehicle General Purpose (AVGP) project led to the procurement of the first generation of the Light Armoured Vehicle (LAV I) vehicle and predominantly consisted of three variants ordered by the Canadian military in the 1970s entering service in 1974. The AVGP variants were the Cougar armoured fighting vehicle, the Grizzly Armoured Personnel Carrier, and the Husky Armoured Recovery Vehicle which were all based on the six-wheeled version of the Swiss MOWAG Piranha I. The Canadian Army retired all AVGP variants beginning in 2005. However, a number of the retired vehicles were transferred to other militaries and police forces, where they continue to serve. The AVGP had propellers and trim vanes for amphibious use, like the eight-wheeled Bison, which was the vehicle family's immediate successor.

Series III Jaguar Sovereign V12 (rear view) The car was significantly facelifted again in April 1979, known as the "Series III", incorporating a subtle exterior redesign by Pininfarina. Changes from the Series II included thicker and more incorporated rubber bumpers with decorative chrome only on the top edge, flush door handles, one-piece front door glass without a separate quarter light, a grille with only vertical vanes, reverse lights moved from the boot plinth to the larger rear light clusters, and a revised roofline with narrower door frames and increased glass area. The option of a sunroof and cruise control were also offered for the first time. The 5.3 L V12, 4.2 L straight-six and 3.4 L straight-six engines carried over from the Series II, with minor changes.

Each stage was a pair of rotors; there were no stators (static vanes), which usually follow the single-rotor section to straighten out the flow. The front propeller and the front half of each stage are attached to a rotating outer casing that encloses the turbine rotor blades, while the back propeller and the back half of each stage are attached conventionally to a central shaft. The counter-rotating turbine can run at half the rpm of a conventional turbine, since counter-rotation doubles the relative velocity, so the engine did not require a reduction gearbox to drive the fan. The GE36 had a hub-to-blade tip radius ratio of 0.425, which as a gearless design reflected about a 75 percent higher value than for geared propfan designs.

Fire-control systems are often interfaced with sensors (such as sonar, radar, infra-red search and track, laser range- finders, anemometers, wind vanes, thermometers, barometers, etc.) in order to cut down or eliminate the amount of information that must be manually entered in order to calculate an effective solution. Sonar, radar, IRST and range- finders can give the system the direction to and/or distance of the target. Alternatively, an optical sight can be provided that an operator can simply point at the target, which is easier than having someone input the range using other methods and gives the target less warning that it is being tracked. Typically, weapons fired over long ranges need environmental information—the farther a munition travels, the more the wind, temperature, air density, etc.

The race teams take advantage of this by placing this ballast at the extreme bottom of the chassis, thereby locating the centre of gravity as low as possible in order to improve handling and weight transfer. The cornering speed of Formula One cars is largely determined by the aerodynamic downforce that they generate, which pushes the car down onto the track. This is provided by "wings" mounted at the front and rear of the vehicle, and by ground effect created by low air pressure under the flat bottom of the car. The aerodynamic design of the cars is very heavily constrained to limit performance and the current generation of cars sport a large number of small winglets, "barge boards", and turning vanes designed to closely control the flow of the air over, under, and around the car.

The speed of the current version of the aircraft is limited by the need to avoid damage to its structure and air intakes. To help lower its radar cross section (RCS), the B-1B uses serpentine air intake ducts (see S-duct) and fixed intake ramps, which limit its speed compared to the B-1A. Vanes in the intake ducts serve to deflect and shield radar emissions from the highly reflective engine compressor blades. The B-1A's engine was modified slightly to produce the GE F101-102 for the B-1B, with an emphasis on durability, and increased efficiency. The core of this engine has since been re-used in several other engine designs, including the GE F110 which has seen use in the F-14 Tomcat, F-15K/SG variants and most recent versions of the General Dynamics F-16 Fighting Falcon.

Overall, the shape and feather architecture of Zhenyuanlong's wings were most similar to those of Microraptor, though the former lacks any sign of the alula feathers which attach to the first finger in modern birds and possibly Microraptor. Detail of the skeleton Long vaned feathers were also present along the length of the tail, and are preserved as a series of long projections of vanes at a 45-degree angle from the tail vertebrae. While preservation makes symmetry difficult to assess, these feathers appear generally similar to the tail feathers of other birdlike dinosaurs that preserve this region, including Sinornithosaurus, Jinfengopteryx, Anchiornis, Eosinopteryx, and Archaeopteryx. This differentiates the tail of Zhenyuanlong from Microraptor and the related Changyuraptor, which had shorter feathers along the base and middle of the tail but large, complex fans at the tip.

The US Naval Air Systems Command intends to award Rolls Royce two contracts to examine the effectiveness of proposed reliability improvements, the first is a software tweak to the engine management software for the compressor guide vanes that internal testing showed could improve surge margin by 0.8% at sea level and 3% at altitude. The second is the discovery that a temperature sensor at the inlet of the compressor sends incorrect readings leading to 2.5% out of 4% steady power shortfall at the compressors correct rotational speed again correctable with a software fix. In addition, Bell Boeing is developing an inlet barrier system to reduce the power loss from the engine ingesting dust and sand particles to supplement the engines existing centrifugal based particle separators as they can only do so much to improve the quality of air they receive.

Robinson Creek in Boonville, California had highly eroded stream banks prior to initiation of a stream restoration project. Stream restoration or river restoration, also sometimes referred to as river reclamation, is work conducted to improve the environmental health of a river or stream, in support of biodiversity, recreation, flood management and/or landscape development. Stream restoration approaches can be divided into two broad categories: form- based restoration, which relies on physical interventions in a stream to improve its conditions; and process-based restoration, which advocates the restoration of hydrological and geomorphological processes (such as sediment transport or connectivity between the channel and the floodplain) to ensure a stream's resilience and ecological health. Form-based restoration techniques include deflectors; cross-vanes; weirs, step-pools and other grade-control structures; engineered log jams; bank stabilization methods and other channel- reconfiguration efforts.

Willett was connected by marriage to the family of John Brown(e), shipbuilder, perennial political office holder, founder of several towns, and one of the wealthiest men in the Plymouth Colony. Although Brown(e)'s origins are uncertain and subject to present debate, he was evidently very well connected in England, as near the end of his life he returned there for several years as executor of the estate of Sir Henry Vane the Elder; the Sir Henry Vanes, elder and younger, played major roles in England at the time of the English Civil War. The Brown(e) family also had ties to earliest Plymouth through the marriage of John Brown(e)'s son, James, to Lydia Howland, daughter of John Howland, one of the Mayflower passengers; Howland collaborated in Willett's early fur-trading efforts.Nathaniel Philbrick.

Information concerning freezing weather conditions in the aircraft manufacturer's maintenance manual had not been included in the airline's Short 360 Operations Manual and was therefore not complied with. The AAIB discovered that large volumes of snow or slush could have accumulated where it would not have been readily visible to the crew during a pre-flight inspection (the engine intakes on a Short 360 are about 2.8 m (9 ft) above the groundAccident report, Appendix III, Figure 4, accessed 13 May 2015). On takeoff this snow changed the engine intake air flow, causing both engines to flame out after both engines' anti-ice vanes were simultaneously opened as per the standard operating procedure. It was noted by the investigators that selecting engine anti-ice 'on' sequentially with a time interval between would have prevented a simultaneous dual engine flameout.

The airflow created by the fans that is entering the tunnel is itself highly turbulent due to the fan blade motion (when the fan is blowing air into the test section – when it is sucking air out of the test section downstream, the fan-blade turbulence is not a factor), and so is not directly useful for accurate measurements. The air moving through the tunnel needs to be relatively turbulence-free and laminar. To correct this problem, closely spaced vertical and horizontal air vanes are used to smooth out the turbulent airflow before reaching the subject of the testing. Due to the effects of viscosity, the cross-section of a wind tunnel is typically circular rather than square, because there will be greater flow constriction in the corners of a square tunnel that can make the flow turbulent.

In 2015, researchers at ARL were tasked with finding a way to prevent flying, micron-sized sand and dust particles from entering the gas turbine engines of military aircraft and damaging the internal machinery. While modern engines have particle separators that can filter out large particles, fine, powder-like sand particles that are smaller than 100 micrometers in size have consistently managed to pass through the engine's combustors and attach to the blades and vanes. As the rotor blades experienced cycles of heating and cooling during operation, the particles melted due to the extreme temperatures and then subsequently hardened onto the turbine blades. As a result, the micron-sized sand particles have frequently destroyed the engine's internal coating, which has led to severe sand glazing, blade tip wear, calcia-magnesia-alumina-silicate (SMAS) attack, oxidation, plugged cooling holes, and, ultimately, engine loss.

Feduccia is best known for his criticisms of the hypothesis, accepted by most biologists, that birds originated from and are deeply nested within Theropoda, and are therefore living theropod dinosaurs. Feduccia's first contribution relative to the origin and early evolution of birds, and their relationship with dinosaurs, was a critical review of the evidence then available for dinosaurian endothermy in 1973. In a 1979 paper, Feduccia and Tordoff argued, against the position taken by John Ostrom, that Archaeopteryx was capable of powered flight, as indicated by the asymmetrical vanes of its primary feathers, a feature found only in flying birds. In a paper coauthored with Storrs Olson in the same year, Feduccia noted that the robust furcula of Archaeopteryx could have served as a site of attachment for a well-developed M. pectoralis major, the principal depressor of the avian wing, responsible for powering the downstroke during avian flight.

In their "open" position, the filters sat edge-on to the axis of the light beam, so that only white light emerged. By rotating the filter sets into the path of the beam, a wide variety of colours could be created—from light pastel shades, to deep saturated hues. A similar mechanism, with three, frosted glass vanes in place of dichroic filters, sat in front of the colour mechanism and was used to provide variable beam diffusion / width control, from a narrow spot to a wide flood. Further beam width control was introduced, with the motorisation of the lamp base; which allowed it to be moved through the reflector, along the beam axis. Another, major departure from the VL1 and VL2, was the use of a custom- made, tungsten lamp as the light source, which ran at a maximum of 53 volts and consumed 475 Watts.

That same year she devoted herself to the Ottawa Convention against land mines and in the poverty-stricken Haiti; she came face to face with children who have been imprisoned in miserable conditions without trial. In 1998, Axelle married Filip Vanes (still her husband and manager at Music & Roses). She also sang the official hymn, "La Cour des Grands", with Youssou N'Dour at the opening ceremony of the Football World Cup in the Stade de France outside Paris, before a television audience of over a billion people. Seven months pregnant with her daughter, Janelle, in her shows devoted to soul and rhythm and blues she was joined by her heroes, Wilson Pickett, Sam Moore, Eddy Floyd, Percy Sledge and Ann Peebles. Axelle supported Amnesty International's grand benefit concert in Paris although, under doctor's orders, 7 months pregnant, she was advised not to perform herself.

Almost equal in diameter, but of differing conical roof designs and heights, and topped with copper-gilt weather vanes, they combine to produce a romantic appearance, which Matthew Williams described as bringing "a Wagnerian to the Taff Valley". The design of the towers was influenced by the work of the contemporary French architect Eugène Viollet-le-Duc, including his restorations of Carcassone and the châteaus of Aigle and Chillon. While the exterior of Castell Coch is relatively true to English 13th-century medieval design—albeit heavily influenced by the Gothic Revival movement—the inclusion of the conical roofs, which more closely resemble those of fortifications in France or Switzerland than Britain, is historically inaccurate. Although he mounted a historical defence (see box), Burges chose the roofs mainly for architectural effect, arguing that they appeared "more picturesque", and to provide additional room for accommodation in the castle.

Temple (1986), 87; Needham (1986b), 123. When the cylindrical lamp was lit, the convection of rising hot air currents caused vanes placed on the top to spin, which in turn rotated painted paper figures of birds and other animals around the lamp. mold for making bronze gear wheels When Emperor Gaozu of Han (r. 202–195 BCE) came upon the treasury of Qin Shi Huang (r. 221–210) at Xianyang following the downfall of the Qin dynasty (221–206), he found an entire miniature musical orchestra of puppets tall who played mouth organs if one pulled on ropes and blew into tubes to control them.Needham (1986c), 158. Zhang Heng wrote in the 2nd century CE that people could be entertained by theatrical plays of artificial fish and dragons. Later, the inventor Ma Jun (fl. 220–265) invented a theater of moving mechanical puppets powered by the rotation of a hidden waterwheel.

In 1994, the 4 open cycle gas turbines were converted into two blocks of combined cycle plants with 425 MW of capacity each and renamed CCP 1 and 2. In 2010, Gas Turbine GT22 of CCP 2 was upgraded with new vanes and blades for its stage 1 and 2 The combined cycle plants 3 to 5 were completed and fully operational by 2004 with 365 MW of capacity each, which involved the repowering of the Stage I oil-fired steam thermal plant. The combined cycle plants 6 and 7 were completed and commissioned by 2012 with 431 MW of capacity each, which involved the repowering of the Stage II oil-fired steam thermal plant. In its early years, the plant used crude oil as fuel to power its turbines; however, this was replaced by natural gas piped from Terengganu on the east coast of Peninsular Malaysia after 1992.

View inside the mill at Braichgoch around 1885 Quarrymen at Braich Goch quarry, 1890 Slate quarrying in the Corris district dates back to the 14th century when the Foel Grochan quarry at Aberllefenni is believed to have first been worked. In 1787, David Williams leased the quarrying and mineral rights at Gaewern and Braich Goch from John Edwards, representing the Vanes Estate. It is not certain when quarrying began on this land, but certainly slate extraction had started by 1812. The early mining took place at Gaewern, the northern of the two quarry areas, under the auspices of the Merionethshire Slate Company. It was not until 1836 that quarrying began at Braich Goch proper, under the name the North Wales Slate & Slab Company. By 1838 the lease, still from (now) Sir John Edwards, was expanded. In 1840 an incline was constructed to easy movement of slate within the quarry. In 1843 the company surrendered the lease to Arthur Causton a civil engineer.

In addition, adjusting the speed of the rotating cage can easily change the intensity of the centrifugal force field in the classification zone to achieve coal fineness control real-time to make immediate accommodation for a change in fuel or boiler load conditions. For the applications where a micrometer- fine pulverized coal is not necessary, the static classifier, which consists of a cone equipped with adjustable vanes, is an option at a lower cost since it contains no moving parts. With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of 100% <100 mesh and 95% <200 mesh, or better. In 1954 a Jet Pulverizer was developed in which operates like a Vertical Pulverizer only the item is pulverized by the high speed air action.

In the gas generator, the intermediate pressure compressor (IPC) is designed by MTU Aero Engines and has five stages. To reduce the complexity of the component, the IPC does not have variable inlet or stator vanes. The high-pressure compressor (HPC) is designed by Rolls-Royce. The HPC has six total stages, with four of them as fixed stages (blisks), and the other two as variable stages. Snecma supplied the combustor, which was based on the combustor of its M88 turbofan fighter engine. To drive the HPC, Snecma also supplied the high pressure turbine (HPT), which also based on the HPT of the M88. The intermediate pressure turbine (IPT) driving the IPC is also a derived component, this time from MTU and based on the IPT of the Turbo-Union RB199 and Eurojet EJ200 turbofan fighter engines. Both the Snecma HPT and the MTU IPT have one stage, but the HPT is unshrouded, while the IPT has a shroud.

Constructed of Kapton in order to withstand the extreme temperatures of space, Sunjammer has a width and height of , giving it a total surface area of over and making it the largest solar sail as of 2013. Despite its huge surface area, Sunjammer has a thickness of only 5 μm, giving it an extremely low weight of about and allowing it to be stored in a space the size of a dishwasher. Once in space, the large surface area of the solar sail would allow it to achieve a thrust of about 0.01 N--roughly the weight of a sugar packet. To control its orientation, and via this its speed and direction, Sunjammer was to use gimballed vanes (each of which is itself a small solar sail) located at the tips of each of its 4 booms, instead of thrusters, completely eliminating the need for any propellant other than the rays of the Sun.

The weight of the water was made to pull a hidden rope to operate temple doors. Some historians have conflated the two inventions to assert, incorrectly, that the aeolipile was capable of useful work. According to William of Malmesbury, in 1125, Reims was home to a church that had an organ powered by air escaping from compression "by heated water", apparently designed and constructed by professor Gerbertus. Among the papers of Leonardo da Vinci dating to the late 15th century is the design for a steam-powered cannon called the Architonnerre, which works by the sudden influx of hot water into a sealed, red-hot cannon. A rudimentary impact steam turbine was described in 1551 by Taqi al-Din, a philosopher, astronomer and engineer in 16th century Ottoman Egypt, who described a method for rotating a spit by means of a jet of steam playing on rotary vanes around the periphery of a wheel.

Mineral concentrates or materials for recycling are dropped into the bath through another hole in the furnace roof or, in some cases, injected down the lance. These feed materials react with the oxygen in the injected gas, resulting in an intensive reaction in a small volume (relative to other smelting technologies). ISASMELT lances contain one or more devices called "swirlers" that cause the injected gas to spin within the lance, forcing it against the lance wall, cooling it. The swirler consists of curved vanes around a central pipe forming an annular flow.

In October 1988, Honda upgraded the C20A V6 engine used exclusively in the KA5 series Legend with a variable geometry turbocharger, calling it the "Wing Turbo" in a Japanese TV commercial to address the modest power available from the previous engine with variable length intake manifold used in earlier models. The turbocharger compressor housing had four vanes made from heat resistant Inconel alloy surrounding the turbine wheel (on the inlet side of it) that would fluctuate based on engine load and transmission gearing above 2,000 rpm to allow for increased airflow into the engine as needed. The turbo compressor could generate as much as of boost, and was paired with a water cooled intercooler installed inside the intake plenum between the cylinder banks to produce net at 6000 rpm and a maximum torque of at 3,500 rpm. The turbo was installed not necessarily to make the engine more powerful, but rather to increase fuel efficiency and reduce emissions, as the Japanese pay a tax on the amount of emissions the car produces.

The water pump, fuel pump, and alternator/generator pulleys were altered, fewer vanes, extra spring, and larger diameter, respectively; to help handle the higher engine speeds. Even the HiPo's fan was unique. Bottom-end improvements included a flaw-free selected standard block, thicker main bearing caps and crankshaft damper/balancer, larger-diameter rod bolts, a crankshaft made from 80% nodular iron as opposed to the regular items at 40%, all were checked for correct 'nodularity' by polishing an area of the rear counterweight and comparing that surface using a magnification arrangement against a picture datum, increased crankshaft counterweighting to compensate for the heavier connecting rod big ends, the increased external counter weighting at the front was split between the crankshaft damper and a supplementary counterweight place adjacent to the front main bearing journal (all designed to reduce the 'bending moment' in the crankshaft at high-rpm), all for high-rpm reliability. The HiPo equipped with a single 4-barrel Autolite 4100 carburetor carried SAE gross ratings of at 6,000 rpm and at 3,400 rpm.

The T56/Model 501 engine has been used in a number of experimental efforts, and as something other than a turboprop powerplant. In early , two Allison YT56-A-6 experimental turbine engines without propellers were added next to existing propulsion engines on flight tests of a Lockheed NC-130B 58-0712 aircraft. The YT56-A-6 produced pressurized air for blowing over control surfaces to demonstrate boundary layer control (BLC), which helped to enable short takeoff and landing (STOL) performance. In , Lockheed and Allison designed another STOL demonstrator, this time for a U.S. Army requirement. Lockheed internal designation GL298-7 involved a C-130E Hercules that was re-engined with 501-M7B turboprops. The 501-M7B produced more power than the normally installed, T56-A-7 engines by about 20% (though the 501-M7B was limited to to avoid additional structural changes), because the introduction of air cooling in the turbine's first-stage blade and the first and second-stage vanes allowed for an increase in the turbine inlet temperature.

Unable to increase (HP) turbine rotor inlet temperature, General Electric chose the expensive path of reconfiguring the CF6 core to increase its basic size. They removed two stages from the rear of the HP compressor, leaving an empty air passage where the blades and vanes had once been. Two booster stages were added to the LP (low pressure) compressor, which increased the overall pressure ratio to 29.3. Although the 86.4 in (2.19 m) diameter fan was retained, the airflow was raised to 1,450 lb/s (660 kg/s), yielding a static thrust of 51,000 lbf (227 kN). The increase in core size and overall pressure ratio raised the core flow, decreasing the bypass ratio to 4.26. In late 1969, the CF6-50 was selected to power the then new Airbus A300. Air France became the launch customer for the A300 by ordering six aircraft in 1971. In 1975, KLM became the first airline to order the Boeing 747 powered by the CF6-50. This led further developments to the CF6 family such as the CF6-80.

The XBQM-108 project was initiated in 1975 by the Aviation and Surface Effects Department of the U.S. Navy's David W. Taylor Naval Ship Research and Development Center.Eilertson 1977 The project was intended to demonstrate the practicality of the 'Vertical Attitude Take-Off and Landing' (VATOL), or 'tailsitter' flight profile for remotely piloted vehicles, as the Navy believed the increasing threat posed by cruise missiles required that aviation assets be dispersed among additional ships of the fleet, which would possess limited space for aviation operations as opposed to conventional aircraft carriers. Based on the MQM-74 Chukar target drone, the XBQM-108A was modified with a revised, delta wing with canard control surfaces. The XBQM-108A was fitted with a thrust vectoring system based on the use of vanes that deflected the engine's exhaust; the aircraft retained the Chukar's recovery parachute and radio guidance system,Parsch 2002 with the addition of a radar altimeter and midcourse guidance unit based on that of the AGM-84 Harpoon anti-ship missile.

On 20 April 2012, Lara made his comeback to the ring after nine months to fight Ronald Hearns for the WBC super welterweight semi-final eliminator spot at the Beau Rivage casino resort in Biloxi, Mississippi. The fight, which was scheduled to go ten rounds, simply lasted one minute and 34 seconds as Lara delivered an impressive TKO in the first round. Referee Keith Hughes decided to stop the fight after Lara had sent Hearns to the canvas with a clean left hook, following the eight-count by the referee, Lara immediately delivered two fast combinations (one of which also required a count) that seemed to be enough to overwhelm Hearns, who seconds before the stoppage appeared to be defenseless upon Lara's final combination. On 10 November 2012, at the Wynn Resort in Las Vegas, Lara faced Vanes Martirosyan, who was undefeated at the time and known for his amateur wins over Andre Berto, Austin Trout, and Timothy Bradley. Lara connected on 42% of his power punches (40/95) while Martirosyan landed 16% of his (27/167) and only 6 jabs throughout the entire fight, according to CompuBox. Lara outlanded Martirosyan in overall punches, 74 to 33.

On 26 February 2014, Rolls-Royce detailed its Trent future developments. The Advance is the first design, could be ready from the end of the 2020s and aim to offer at least 20% better fuel burn than the first generation of Trents. The Advance bypass ratio should exceed 11:1 and its overall pressure ratio 60:1. In previous Trents, the HP spool was similar and the engine grew by expanding the intermediate pressure spool work. The Advance reverses this trend and the load is shifted towards the high pressure spool, with a greater pressure ratio, up to 10 stages compressor compared to 6 on the Trent XWB and a two-stage turbine against the current single-stage, while the IP compressor will shrink from the 8 stages of today's XWB to 4 and the IP turbine will be single instead of two stages. The Advance3 ground-based demonstrator includes lean burn, run before on a Trent architecture only; ceramic matrix composite (CMC) for turbine high-temperature capability in the first stage seal segments and cast-bond first stage vanes; hybrid ball bearings with ceramic rollers running on metallic races, required to manage high load environments inside smaller cores.

Nacelle installation on the A350 XWB On 26 July 2017, Airbus delivered the 100th A350, on track for 10 per month by 2018 end, and over the first 30 months most engine removals have been to stagger the on- wing life of a particular aircraft or to collect in-service data; nine in ten of the Trent XWBs have a long-term service agreements with Rolls, which has designated seven shops as MRO providers: its Derby facility, its joint ventures with HAECO, SIAEC, and independents Delta TechOps, Mubadala and Air France Industries-KLM. It passed one-million flight hours in October 2017 without any in-flight disruptions and with a dispatch reliability of 99.4%. By February 2018, it has completed 1.3 million flight hours with a 99.9% dispatch reliability. It took two years to reach one million flying hours and nine months for the second million by July 2018, as 500 were delivered, it has a 99.9% dispatch reliability and had no in-flight shutdown yet. As the fleet accumulated 2.2 million flight hours and the leading engine has operated 3,500 cycles, an Iberia A350-900 delivered at the end of July diverted to Boston after an inflight shutdown at 41,000ft on the September 11, 2018 flight from New York to Madrid, apparently due to slight secondary damage on variable stator vanes.
