In applied mathematics, a steerable filter is an orientation-selective convolution kernel used for image enhancement and feature extraction that can be expressed via a linear combination of a small set of rotated versions of itself. As an example, the oriented first derivative of a 2D Gaussian is a steerable filter. The oriented first order derivative can be obtained by taking the dot product of a unit vector oriented in a specific direction with the gradient. The basis filters are the partial derivatives of a 2D Gaussian with respect to x and y.

"Multiple Unit Steerable Antenna" refers to an array of rhombic antennas used for high frequency (3–30 MHz) trans-Atlantic communication, "steerable" by the act of connecting several antennas together via a phasing circuit, thus achieving maximum antenna gain in the required direction. The Musa connector was developed by the British Post Office, as a reliable and readily deployed means of achieving the desired configuration. Some time after commercial television appeared around 1936, the Musa connector came to be used as a standard video connector; its distinctive feature being that unlike most other types of coaxial connector, it is engaged and disengaged by a straight push-pull action, making it ideal for patch bays. In such professional telecommunications and video applications, the connector performed well until the end of analogue (525 or 625 line) television.

Sometimes this term is applied only to non- rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship (which may then be rigid or non-rigid). Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back. These soon became known as blimps.

Controls are actuated by push-pull cables, while the elevator trim is electric. The nosewheel is steerable. The aircraft's recommended engine power range is and standard engines used include the Hirth F-23, the Rotax 503 and the Rotax 582 two- stroke powerplants. Construction time from the supplied standard kit is estimated as 350 hours, although a quick-build kit is also available.
|
|
The wing is equipped with full span ailerons. The conventional landing gear includes sprung-steel main gear and a similarly sprung steerable tail wheel. The open cockpit design provides good visibility while taxiing. The standard engine supplied by the manufacturer for the single seat version was the Rotax 277, but it was reported that the aircraft was underpowered with that engine installed.

Although this is a common program, each country operates its own share of the payload. The satellite provides an encrypted, 3 Gbit/s throughput, using mostly Ka-band links. It carries 14 antennas including 7 mobile spot antennas, enabling positioning of steerable 1750-km diameter spot beams over operational theaters requiring a high bandwidth. France owns five beams and Italy, two.
|
|
The mainwheels had brakes and the tailwheel was steerable. The Commuter made its first flight in 1958. Described as an STOL aircraft, it had respectable takeoff and landing characteristics, though no records comparing performance with open and closed Vacua-cells seems to have survived. A more recent study suggests the known figures were not exceptional given its thick wing, weight and power.
|
|
The wide track and a steerable nosewheel made the aircraft easy to handle on the ground, and the short landing gear avoided the need for access ladders and service stands. The aircraft was designed to be simple to maintain, with more than 100 access panels and doors. An experienced ground crew could change an engine in about half an hour.

|
The Jora normally has a fixed, tricycle undercarriage, though a conventional undercarriage is an option. The mainwheels are mounted on inverted tubular steel A-frames, hinged to the lower fuselage; the nosewheel is on a forward-leaning leg and is steerable. Some Joras have single cantilever main legs. Rubber springs are used on all legs; the main wheels have hydraulic disc brakes.
|
|
The satellite has three beams. A fixed beam covers almost all of Europe as well as north-western Africa. There are also two steerable beams - the first, "S1", co-focused with the fixed beam but with a Europe-only footprint, and a second, "S2", aimed to central Europe. This beam features many transponders with low symbol rates, used for satellite news gathering.

|
Steerable motors are used to drill the kick-off point. When drilling the kick-off point be sure to avoid drilling a soft formation immediately below a hard one. In hard abrasive formations the high-side forces at kick off can cause severe bit shank wear. Ideally the kick-off point should be selected in a non-abrasive homogenous formation.

|
A tricycle landing gear with steerable nosewheel was envisioned. With the revised specifications, the Excalibur could now effectively compete with the near monopoly Douglas had on the airliner market. Its projected performance was better (except in range) than the Boeing 307. The revision of specifications was partially due to a request from Pan American Airlines; their influence also caused the addition of the third tailfin.

Turbine blades continue to increase in size, sometimes necessitating brand new logistical plans, as previously-used routes may not allow a larger blade. Specialized vehicles known as Schnabel trailers are custom-designed to load and transport turbine sections: tower sections can be loaded without a crane and the rear end of the trailer is steerable, allowing for easier maneuvering. Drivers must be specially trained.

Leadless pacemakers are devices that are small enough to allow the generator to be placed within the heart, therefore avoiding the need for pacing leads. As pacemaker leads can fail over time, a pacing system that avoids these components offers theoretical advantages. Leadless pacemakers can be implanted into the heart using a steerable catheter fed into the femoral vein via an incision in the groin.

Ahead of the pilot, the fuselage bays were built from steel rather than wood spars. The single-axle main undercarriage carried wheels with disc brakes; there was a central skid to prevent nosing over and fenders under the wingtips. The tailskid was steerable and sprung. The Seely was a three-bay biplane with greater wing area than the Tourer, with ailerons on both upper and lower wings.
|
|
Its track was determined by the separation of the outer engines, as each vertical, shock absorbing oleo strut was fixed to the second wing spar within the nacelle. Instead of an axle each wheel hub was mounted on a near-horizontal V-strut, hinged on the lower fuselage longeron. The wheels had hydraulic brakes. At the rear there was an oleo-damped, steerable tailskid.

A picture of Bartlow Hills, taken using kite aerial photography. The most important aspect of any kite used to lift a camera is stability. Generally, single lined kites are used as they allow very long line lengths and need less intervention from the flyer than steerable designs. Almost any stable kite design can be used to lift lightweight camera rigs (up to approx 500g/1 lb).

Such combinations of construction types were not common. While the Sedan mated a fabric-covered fuselage to all-metal wings, the contemporary Cessna 170 mated an all-metal fuselage to fabric-covered wings. Also unique to the Sedan, among Aeronca designs, are the single-piece wing struts. The landing gear of the Sedan is in a conventional arrangement, with steel tube main gear, and a steerable tailwheel.

In conventional usage, the term aerostat refers to any aircraft that remains aloft primarily using aerostatic buoyancy. Historically, all aerostats were called balloons. Powered types capable of horizontal flight were referred to as dirigible balloons or simply dirigibles (from the French dirigeable meaning steerable). These powered aerostats later came to be called airships, with the term "balloon" reserved for unpowered types, whether tethered or free-floating.

There was a small, steerable tailwheel. The Weymann W-100 first flew between late June and early July 1933, piloted by Barbot, though the location is not recorded. By August it had been further tested at Villacoublay, had returned to the factory by mid-August and was back at Villacoublay in September. There seem to be no further references to the W-100 in the French journals after this date.

Balloonists sought a means to control the balloon's direction. The first steerable balloon (also known as a dirigible) was flown by Henri Giffard in 1852. Powered by a steam engine, it was too slow to be effective. Like heavier than air flight, the internal combustion engine made dirigibles-- especially blimps--practical, starting in the late 19th century. In 1872 Paul Haenlein flew the first (tethered) internal combustion motor-powered balloon.

The pilot is accommodated on an open seat without a windshield. The landing gear features suspension on all wheels and a steerable nosewheel. The Cuyuna 430R engine of is mounted in front of the wing, above the pilot. Due to its introduction just before the collapse of the US ultralight industry in 1984, the design was not a commercial success and only a small number were completed and sold.

Peter Powell at the 1st AKA Convention in Ocean City, Maryland in 1978. Peter Trevor Powell (29 June 1932 – 3 January 2016)The Times Obituary - Peter Powell, 8 February 2016. p48 was a British kite maker who developed a steerable kite in 1972, using dual lines. Very early on, Powell's kites had spars made of ramin (Gonystylus) which were later replaced with aluminium tubing and, later still, by glass fibre spars.

The engine mountings were steel tube structures supported by the longerons; the engine cowlings were most prominent above the wings. The main legs of the track landing gear, with fairings mounted on the front of, them retracted rearwards into the cowlings. The undercarriage was completed with an oleo mounted, steerable tailwheel. There were fuel tanks in the central section of the wings between both the engines and the longerons.

La France, the first successful airship The ballonet was first described in 1783 by Jean Baptiste Meusnier, then a lieutenant in the French Army. However his own airship project was unsuccessful. In 1784 professor Jacques Charles and the Robert brothers built an elongated, steerable craft that followed Jean Baptiste Meusnier's proposals. Their design incorporated Meusnier's internal ballonnet (air cell), a rudder, and oars for propulsion, which proved useless.

Nelson Hummingbird PG-185B BB-1 Dragonfly The first Nelson-Bowlus glider was the Nelson Bumblebee with a pod-and-boom fuselage two-seat powered sailplane [NX1955]. The Bumblebee in 1945-46 was built with a Righter O-45 16-hp four- cylinder engine. The prototype Bumblebee had a fully retractable tricycle landing gear, operated manually by the pilot. The nose gear was steerable with miniature shimmy dampeners and a lock.

A tag axle is a dead axle situated behind a drive axle. Dead axles are also found on semi trailers, farm equipment, and certain heavy construction machinery serving the same function. On some vehicles (such as motorcoaches), the tag axle may be steerable. In some designs the wheels on a lazy axle only come into contact with ground when the load is significant, thus saving unnecessary tire wear.

The entire lander would lift into a lunar parking orbit and eventually power itself onto a return trajectory. The crew capsule would separate from the powered stage and orientate itself for reentry similar to the Apollo capsule with its heat shield towards the atmosphere. The capsule would deploy a steerable parasail parachute for a land recovery, potentially at Kennedy Space Center. The lander section would burn up in the atmosphere.

Crane, Dale: Dictionary of Aeronautical Terms, third edition, page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, From the Ground Up, page 11 (27th revised edition) Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless Whatsit was one of the first to have a steerable nose wheel.

|
The pilot sits on the seat in the open air, with no windshield. The landing gear is of tricycle configuration and features a steerable nosewheel and hydraulic brakes. The Avion can be assembled for flight in 30 minutes. The Avion underwent a complete engineering stress analysis by Bob Hovey, the designer of the Hovey Delta Bird and Hovey Whing Ding II. The Avion was designed to +6/-4g.

In the north-south direction, the telescope operates as a phased-array and is steerable by varying the phase gradients The telescope can be operated in either total power or correlation mode. In each mode, 12 beams are formed; beam 1 is the southernmost beam and beam 12 is the northernmost. These 12-beam systems are useful in sky survey observations. Recently, the reflecting surface of the ORT has been refurbished.

The conventional landing gear features a steerable tail wheel attached to the rudder. The controls are two-axis, with a side-stick that laterally activates the rudder to induce roll and which longitudinally activates the elevator for pitch control. No rudder pedals are installed and the wing construction is greatly simplified by the elimination of ailerons. The open frame fuselage consists of 6061T6 aluminum tubing and a single open pilot's seat.
|
|
The aircraft is made from aluminum tubing, foam, fiberglass, with the wings finished in doped aircraft fabric covering. Its span wing features a laminar-flow airfoil, 50%-span elevons and wing tip rudders that can both be deployed simultaneously for use as air brakes. The aircraft has a 22:1 glide ratio. The F.L.A.C. has laminated fiberglass main landing gear legs and a nose wheel that is steerable.
|
|
The landing gear features main wheel suspension and a steerable nosewheel. The airframe was proof tested to +4.5/-2.25 g. The complex wing does give the aircraft good gliding performance, achieving a 13:1 glide ratio and a minimum sink speed of 260 ft/min (1.3 m/s). However the complexity of the wing construction lead to the commercial failure of the aircraft design and few were produced.

Central inflation systems originally claimed to eliminate the need for pressure- monitoring systems. Some major inflation systems are Meritor PSI, Hendrickson International, Stemco AERIS and Vagia (used mostly in South America). They have not yielded a complete solution, since they do not solve all the issues (i.e., no support for the steerable axle), and they bring new issues with maintenance of the rotary couplings in the hub caps.

The 400 features optional speedbrakes mounted on the wing's top surfaces. The 400 nosewheel is not directly steerable; directional control while taxiing is accomplished using differential braking on the mainwheels.A Tale of Two Cessnas, Flying Magazine, Vol. 135., No. 5, May 2008, p. 30 Initially sold simply as the Cessna 400, the aircraft was given the marketing name Corvalis TT for twin turbocharged by Cessna on 14 January 2009.

The fixed tricycle undercarriage had fuselage mounted cantilever steel spring legs; the main wheels had brakes and the nosewheel was steerable. Initially the SVIT was powered by an 85 hp (63 kW) Continental C85 flat four engine. This was used for its first flight (2 July 1968) and took it through to certification in April 1969. That engine was then immediately replaced with a 100 hp (75 kW) Continental O-200.

The DeviDrill, Devico AS directional core barrel and rotary steerable system, was launched in 1988. It was in use until 2001 when the wireline version of the DeviDrill was introduced. The new version was a big improvement as it allowed the drill string to stay in the borehole during steering and coring. Devico AS has developed their own set of borehole survey instruments to be used together with the DeviDrill.

Before aircraft commonly used tailwheels, many aircraft (like a number of First World War Sopwith aircraft, such as the Camel fighter) were equipped with steerable tailskids, which operate similar to a tailwheel. When the pilot pressed the right rudder pedal — or the right footrest of a "rudder bar" in World War I — the skid pivoted to the right, creating more drag on that side of the plane and causing it to turn to the right. While less effective than a steerable wheel, it gave the pilot some control of the direction the craft was moving while taxiing or beginning the takeoff run, before there was enough airflow over the rudder for it to become effective. Another form of control, which is less common now than it once was, is to steer using "differential braking", in which the tailwheel is a simple, freely castering mechanism, and the aircraft is steered by applying brakes to one of the mainwheels in order to turn in that direction.

Instruments currently located at the Sagamore Hill RSTN site include the Radio Interference Monitoring Sets (RIMS) and the Solar Radio Spectrograph (SRS). The RIMS system consists of three dishes observing at eight different frequencies, while the SRS system consists of two antennas observing two different frequency bands. The site previously included a 150-foot fully steerable antenna, which was installed in 1963 and moved to Millstone Hill in Westford, Massachusetts in 1978.

The Pushchino Radio Astronomy Observatory has four notable radio telescopes (RT 22), each with mirrors at 22 meters. Constructed in 1959 these are fully steerable, and are designed to operate in millimeter and centimeter ranges of wavelength. Added to the equipage is the DKR 1000, a wide-band radio telescope instrument, on-line in 1964, and operating in the meter wavelength range. The DKR 1000 has arms that are 40 by 1000 meters.

After the first two were completed the remainder were built from metal in place of wood. The design features an all-flying stabilator with an anti-servo tab, spoilers on the wing's top surface and dive brakes on the bottom. The Nelson H-59 4-cylinder engine was mounted on a retractable mast aft of the bubble canopy. The aircraft has two wheels in tandem, the front being steerable and connected to the rudder pedals.

Short-range communications between the CSM and LM employed two VHF scimitar antennas mounted on the SM just above the ECS radiators. A steerable unified S-band high-gain antenna for long-range communications with Earth was mounted on the aft bulkhead. This was an array of four diameter reflectors surrounding a single square reflector. During launch it was folded down parallel to the main engine to fit inside the Spacecraft-to-LM Adapter (SLA).

The next Willows airship the Willows No.4 was slightly smaller but more streamlined than the No. 3. Completed in 1912 it had a 24,000 cubic feet (680 m³) capacity, a length of 110 ft (33.5 m) and a diameter of 20 ft (6,10 m). The envelope had a keel on which was mounted a Anzani engine driving two four-bladed steerable propellers. Below the keel was suspended a two-man gondola.

In the 1950s Hamilton set out to try to build a boat that could navigate the shallow fast flowing rivers where he lived. The rivers were too shallow for propeller driven boats to navigate as the propeller would hit the river bottom. He investigated the American Hanley Hydro-Jet, a model which drew in water and fired it out through a steerable nozzle underneath the boat. Even when further adapted it did not work well.

She then navigated to the desired air current which would take her to her destination. Her balloon airship was also steerable by the shifting of her weight and by fin rudder apparatuses exposed to the air currents. Not all of her flights were safely accomplished. The demonstration event at the Chenango county fairgrounds at Norwich, New York, on September 9, 1880, went smoothly at first: Myers' balloon, named "Aerial", ascended quickly upon liftoff.
|
|
The Parasol has conventional three-axis controls, including half-span ailerons. The main landing gear is bungee-suspended and the tail has a steerable skid. Brakes were optional and taxiing the aircraft without them was described as "a little tricky". As is the case with many parasol designs where the pilot sits directly underneath the wing on the aircraft's center of gravity, the cockpit access is restricted by the close proximity of the wing.
|
|
It will also have a small robotic arm, similar to the MIR Lyappa arm, to move the modules to different ports. Electrical power is provided by two steerable solar power arrays, which use photovoltaic cells to convert sunlight into electricity. Energy is stored to power the station when it passes into the Earth's shadow. Resupply ships will replenish fuel for the module's propulsion engines for station-keeping, to counter the effects of atmospheric drag.

A comparable joystick unit was used for the contemporary American Azon steerable munition, strictly to laterally steer the munition in the yaw axis only. This German invention was picked up by someone in the team of scientists assembled at the Heeresversuchsanstalt in Peenemünde. Here a part of the team on the German rocket program was developing the Wasserfall missile, a variant of the V-2 rocket, the first ground-to-air missile.

Following retrofits to two existing vessels, the newly built Röthelstein was only the third vessel ever to be fitted with an electric podded propulsion system where the propulsion motors driving the propellers are located inside steerable gondolas. She was also the first vessel with Azipod units in pulling configuration where the propellers are facing forwards to improve efficiency and icebreaking performance.Experience with Azipod® propulsion systems on board marine vessels. ABB Review 2/1999.

The disadvantage is that it is far larger and heavier for a given aperture area than a parabolic dish, and must be mounted on a cumbersome turntable to be fully steerable. This design was used for a few radio telescopes and communication satellite ground antennas during the 1960s. Its largest use, however, was as fixed antennas for microwave relay links in the AT&T; Long Lines microwave network. on Albert LaFrance [long- lines.

Purely from the standpoint of detection, towed hydrophone arrays offer a long baseline and exceptional measurement capability. Towed arrays, however, are not always feasible, because when deployed, their performance can suffer, or they can suffer outright damage, from fast speeds or radical turns. Steerable sonar arrays on the hull or bow usually have a passive as well as active mode, as do variable- depth sonars Surface ships may have warning receivers to detect hostile sonar.

However, the bow propellers are not suitable for polar icebreakers operating in the presence of harder multi-year ice and thus have not been used in the Arctic. Mastera, one of the first double acting tankers, in open water. In ice, the vessel will proceed stern first. Azimuth thrusters remove the need of traditional propellers and rudders by having the propellers in steerable gondolas that can rotate 360 degrees around a vertical axis.

There is a baggage compartment with a maximum load of . Aft of the cabin the fuselage tapers, with an upswept underside, to a tall swept fin and balanced rudder. The rectangular tailplane, externally braced from above and carrying separate, unbalanced elevators with a cut-out for rudder movement, is mounted on the fin a little above the fuselage. The tricycle undercarriage has mainwheels on sprung cantilever legs and a steerable oleo sprung nose wheel.

The aircraft's structure is entirely made from wood, with the wooden fuselage built from wood strips arranged in a geodesic form, resulting in a very strong and light aircraft with redundant load paths. Like the Cub, both the wings and fuselage on the Super Koala are covered with doped aircraft fabric. The wings are strut-braced and utilize jury struts. The landing gear is bungee suspended and the tail wheel is steerable.

Eutelsat 33B, formerly known as Eutelsat W5, Eutelsat 3F1, Eutelsat W1, Eutelsat 70A and Eutelsat 25C, is a telecommunications satellite owned by Eutelsat Consortium. Eutelsat W5 provides coverage to Western Europe, Central Asia, the Middle East. The satellite can use either 6 steerable beams or 2 fixed beams to provide the coverage. Eutelsat 70A was used to provide video distribution and contribution links, occasional-use video as well as Internet backbone connections.

In January 2011, NRO offered NASA two space optical systems with 2.4 m diameter primary mirrors, similar to the Hubble Space Telescope, yet with steerable secondary mirrors and shorter focal length resulting in a wider field of view. These could either be spare hardware from the KH-11 program, or optics from the cancelled FIA program. The satellites were reportedly stored in a clean room facility at ITT Exelis in Rochester, NY.

Hughes, and the 601 platforms, were acquired by Boeing in 2000. The last commercial 601 satellite was ordered in 2001 and launched in 2004. The NASA Space Communications and Navigation (SCaN) Program Office in December 2007 selected the BSS-601HP for its third generation TDRS spacecraft, adding the two 15-foot (4.5m) diameter steerable antennas. The TDRS-M satellite, launched on August 18, 2017, became the last 601 satellite to reach orbit.

A vertical axis Twisted Savonius type turbine. Vertical-axis wind turbines (or VAWTs) have the main rotor shaft arranged vertically. One advantage of this arrangement is that the turbine does not need to be pointed into the wind to be effective, which is an advantage on a site where the wind direction is highly variable. It is also an advantage when the turbine is integrated into a building because it is inherently less steerable.

In addition to the basic Widebeam and Superbeam, Hot Bird 3 and Hot Bird 4 were equipped with a Steerable Beam which could be oriented anywhere visible from 13° E, either northern or southern hemispheres. Hot Bird 4 and Hot Bird 5 were the first in the world to be equipped with SKYPLEX for on-board multiplexing of digital signals into a single DVB stream which could be received in the downlink by standard IRDs.

Beginning with the advent of electronic sensors, the concept of perimeter security evolved rapidly to include more modern, technological solutions. This allows both private entities and governments to protect wider areas with less manpower involved. In World War II radar was first introduced to detect airplanes and ships and later ground targets. Later, ground surveillance radar was coupled with steerable cameras that were automatically cued onto targets for quick evaluation of the threat.

The Champion was created by scaling down the Avid Mark IV and narrowing the wider fuselage into a single seat design intended to comply with the US FAR 103 Ultralight Vehicles category. The design is a conventional tractor configuration, featuring tube and aircraft fabric construction. The main landing gear is bungee suspended and includes a steerable tailwheel. Like other Avid designs, the wing has an under-cambered airfoil, Junkers style ailerons and scalloped trailing edges.

Testing includes an unprecedented continuous 200 mile test run at an average of 28 miles per hour. The 2005 version of Sandstorm used six fixed LIDAR units, the steerable LIDAR, and short- and long-range radar. Sandstorm competed in the 2005 DARPA Grand Challenge on October 8th, qualifying third from the pole position behind Stanley and finished in 7 hours, 5 minutes, placing 2nd out of the five vehicles to complete the 132-mile course.

The satellite is built to provide high speed data transmission services to Africa, Latin America and Europe. It is based on Orbital ATK's Star-3 Bus, delivering 64 28 GHz fixed beams covering Africa and parts of Europe. There are also four independent steerable beams that can serve Africa, South America and Europe. The capacity will partially be used to allow Avanti to expand into new markets and provide growth for existing markets.

The Bengali is powered by a 75 kW (100 hp) Rolls-Royce built Continental O-200 flat four piston engine driving a fixed pitch propeller. The main fuel tank, holding 67 L (14.8 Imp gal) is in the fuselage under the baggage space, with more fuel held in a pair of leading edge wing tanks. It has a fixed tricycle undercarriage. The mainwheels have hydraulic brakes and the nosewheel is self centring though not steerable.

A choice of flat four engines offers either the 59.6 kW (80 hp) Rotax 912UL or the 73.5 kW (98.6 hp) Rotax 912 ULS. The Sirius is fitted with a fixed tricycle undercarriage with mainwheels fuselage mounted on composite cantilever spring legs. The nosewheel is steerable and the mainwheels have brakes; all wheels are almost completely enclosed in spats. The company has also developed a float installation for the TL-3000 to allow water operations.

The Swati is a low-wing cantilever monoplane with a steel tube fuselage covered in fabric at the rear and composite material at the front. It has metal tail surfaces and wooden wings and a fixed landing gear with a steerable nosewheel. The Swati has a Lycoming O-235 piston engine at the front driving a two-bladed propeller. Directorate General of Civil Aviation ordered 40 to be distributed to civil flying clubs in India.

If there was an obstacle that the driver had avoided, the trailers might eventually hit it as they rounded a corner. To solve this problem, the new trailers were all equipped with steerable wheels. Steering commands were sent from the control cab to each set of wheels in turn, so they started turning at the same point where the driver had. This allowed the train to make sharp right-angle turns, for instance.

In order to determine the transmit and receive angle of each beam, a multibeam echosounder requires accurate measurement of the motion of the sonar relative to a cartesian coordinate system. The measured values are typically heave, pitch, roll, yaw, and heading. To compensate for signal loss due to spreading and absorption a time-varied gain circuit is designed into the receiver. For deep water systems, a steerable transmit beam is required to compensate for pitch.

It had twenty three transponders powered by TWTA with and output power of 85 Watts. It had a wide beam footprint that covered Japan, southern and eastern Asia, and Hawaii. It's Ka band section had a single gridded shaped antenna on the East side for the wide beam, and a Nadir shaped surface antenna for the steerable beam. It had four 100 MHz transponders powered by TWTA with and output power of 70 Watts.

Space Communications Corporation (SCC) was founded in 1985, the same year as the original companies that later formed JSAT. On September 2001 SCC ordered its third BSS-601 based spacecraft, Superbird-6. It was to use the 158° East position and offer a Japan wide beam service in Ku band and Ka band, plus steerable Ka band spot beams. It was expected for a Fall of 2003 launch aboard an Atlas IIAS.

The non- retractable tailwheel is steerable. The Carat is powered by an air-cooled, four cylinder, Volkswagen derived, 40 kW (54 hp) Sauer S1800 piston engine. This drives the unique feature of the Carat, its folding two blade propeller: the blades fold forward like spears to minimize drag when the engine is off. This is in contrast to other motorgliders which mostly either store the propeller inside the fuselage, or merely feather the propeller blades.

The T-10D and T-11 parachutes are partially steerable using the parachute risers and students are taught the different techniques to steer their chutes into the wind and aim for the Point of Impact at the center of the Drop Zone. The second week completes a soldier's individual skill training and begins building team effort skills. Once successfully completing the skills required and the physical fitness requirements, a soldier progresses to jump week.

Work on the Ariane 5 EAP motors has been continued in the Vega programme. The Vega 1st stage engine – the P80 engine – is a shorter derivation of the EAP. The P80 booster casing is made of filament wound graphite epoxy, much lighter than the current stainless steel casing. A new composite steerable nozzle has been developed while new thermal insulation material and a narrower throat improve the expansion ratio and subsequently the overall performance.

The propeller air stream can be used to inflate the ballonets and so the hull. In some models, such as the Skyship 600, differential ballonet inflation can provide a measure of pitch trim control. The engines driving the propellers are usually directly attached to the gondola, and in some models are partly steerable. Blimps are the most commonly built airships because they are relatively easy to build and easy to transport once deflated.

The undercarriage consists of a semi-retractable mainwheel fitted with a disc brake, steerable tailwheel and optional outrigger wheels on flexible struts at the wing-tips. Accommodation for two pilots is provided side by side under an aft-hinged upward-opening canopy. The Ogar was certified for simple aerobatics. Of the 64 production aircraft, 41 were exported;those destined for the United States were powered by dual-ignition, turbocharged, Revmaster/Volkswagen VW 2962 engines.

To reach the ground, he must rappel from a letdown line tied into his parachute risers. Most paratroopers landed within the boundaries of the drop zone and assembled in the South East corner of Luzon Tree Drop Zone. Numerous soldiers who landed in the trees found themselves suspended up to 40 feet above the ground. These soldiers rappelled to the ground by securing a letdown line to the risers of their MC1-1 steerable parachute.

Biographer Gordon Ogilvie credits Pearse with "several far- sighted concepts: a monoplane configuration, wing flaps and rear elevator, tricycle undercarriage with steerable nosewheel, and a propeller with variable-pitch blades." Pearse ended his flying experiments about 1911, but continued aviation work, attempting to develop a vertical takeoff and landing aircraft and rotorcraft. Late in life he became bitter and paranoid and was admitted to a mental hospital in 1951, where he remained until his death.

Folding the wings can be accomplished by one person in a few minutes, with the struts supporting the wing. The nose wheel is steerable, dual controls were factory standard, while the vertically-hinged cockpit doors were an option. With no occupants the aircraft sits on its tail. The SS-11's acceptable installed engine power range is and the standard engines used are the Rotax 503 and the Rotax 582 twin cylinder, two-stroke powerplants.

Aeromarine developed the AM-1, AM-2, and AM-3 designs in 1923 for an earlier proposal. The BM-1 was a clean-sheet design for the new effort. The BM-1 was a single place biplane with conventional landing gear and a steerable tail skid. The aircraft used a dropable main fuel tank between the main gear to meet crashworthiness requirements and a small header tank of 10 gallons in the upper wing.
|
|
The fuselage of the MG-1 was steel framed and fabric covered with the exception of a glass fibre engine cowling. This housed a conventionally nose mounted, 74.5 kW (100 hp) flat four Continental O-200 piston engine driving a non- retractable propeller. Its cockpit seated two side by side under a rearward sliding canopy. The conventional undercarriage had main wheels with rubber cord shock absorbers and brakes, assisted by a steerable tailwheel.

In lunar orbit, the crew faced a series of problems. Duke was unable to get the S-band steerable antenna on the LM Orion to move in the yaw axis, and therefore could not align it correctly. This resulted in poor communications with the ground stations, and consequently a loss of the computer uplink. This meant that Duke had to copy down 35 five-digit numbers and enter them into the computer.

The Acrostar is powered by a 220 hp (165 kW) Franklin 6A-350-C1 six cylinder horizontally opposed piston engine. This is mounted in a steel frame which is integral with the fixed cantilever main undercarriage and its optionally streamlined, tapering legs and faired wheels. This arrangement places the main landing gear further forward than usual, providing a drag moment to oppose that of the fin in vertical flight. The tailwheel is steerable.
|
|
The airframe of the 180 is all-metal, constructed of aluminum alloy. The fuselage is a semi-monocoque structure, with exterior skin sheets riveted to formers and longerons. The strut-braced wings, likewise, are constructed of exterior skin sheets riveted to spars and ribs. The landing gear of the 180 is in a conventional arrangement, with main gear legs made of spring steel, and a steerable tailwheel mounted on a hollow tapered steel tube.
|
|
The landing gear features fiberglass suspension and the tailwheel is steerable. The wings are quickly removable and the whole aircraft was designed to be transported on the roof of a 1980s-era station wagon, taking 20 minutes to assemble or disassemble. The standard engine supplied was the Rotax 277 single cylinder, two-stroke aircraft engine. Production ended in 1994 and the conventional-tailed, but otherwise similar US Aviation Cumulus commenced production in 1995.

This was the first time that an ordinary spherical balloon could be controlled by a person. Myers then incorporated new features into balloons based on Carlotta's findings. For a more efficient steerable airship vessel he made his next balloon gas bag bottom flat so that it would act like an inclined plane. This airship that lifted a rider consisted of a cigar-shaped hydrogen balloon that looked like an inverted boat wrapped in netting.

The flat cabin top continued behind the cabin to the engine housing, where an 82 kW (110 hp) Alfa-Romeo 110-I 4-cylinder inverted air-cooled in-line engine was mounted in pusher configuration. The LB.2 was one of the first Italian aircraft with a tricycle undercarriage. This was non-retractable, with the mainwheels on short vertical oleo legs wing mounted at the root of the tailbooms. The nosewheel was steerable.

With the beginning of the 1950s Becker started working on his invention, a ship propeller that is steerable through 360 degrees. In 1951 the company's own motorboat was equipped with the first Schottel Rudderpropeller, which Becker called SRP. Soon, the rudderpropeller was known as a propulsion unit for small fast patrol craft for the German police and government. At the end of this decade Schottel opened its first subsidiary abroad in the Netherlands.

IEEE Spectrum, 17 February 2009. Web. 1 March 2010.. For the HI-MEMS cybernetic bug to be considered a success, it must fly from a starting point, guided via computer into a controlled landing within of a specific end point. Once landed, the cybernetic bug must remain in place. In 2020, an article published in Science Robotics by researchers at the University of Washington reported a mechanically steerable wireless camera attached to beetles.

The undercarriage is fixed and conventional, with mainwheels on hinged cantilever tube steel legs which have horizontal extensions under the fuselage that are rubber sprung to the centre structure. The mainwheels have brakes and the tailwheel is steerable. The prototype LS.60 was built at the Breguet factory and first flew on 27 April 1961. It was declared competition winner and production of 200 aircraft was anticipated, but this did not happen and only the prototype was ever built.

The leading edge is a plywood D-cell. The aircraft features dual controls and a retractable tricycle landing gear with a steerable nose wheel. The engine is started by a ratchet- wire recoil start system that allows restarts in flight, as well as on the ground. Federal Aviation Administration certification of the type was achieved on 21 April 1947, with Nelson Aircraft Corporation as the certificate holder and the type officially known as Nelson Auxiliary Power Glider BB-1.

23 On entering service, two stern- mounted, short-length torpedo tubes for Mark 20 anti-submarine torpedoes. However, the development of steerable wire-guided torpedoes made the less- capable aft-firing torpedoes redundant; they were closed off, and later removed during a refit.Shaw, HMAS Onslow, p. 19 Ovens was laid down by Scotts Shipbuilding and Engineering Company at Greenock, Scotland on 17 June 1966, launched on 4 December 1967, and commissioned into the RAN on 18 April 1969.

Both of these ideas were probably incorporated into his powered kite projects, where a steerable tractor engine and propeller were attached to a fuselage (nacelle) suspended from a large biplane or triplane kite. Dorand developed these in the period from 1908-1910. In 1912 he became an engineering battalion commander and head of the Military Aeronautical Laboratory at Chalais-Meudon. In 1914 he became its director, but it was closed in 1915 because of the First World War.

The Zing was designed as a higher performance version of the Cloudster, with a smaller wing with a span less than the Cloudster, yielding higher cruise speeds at the price of a higher stall speed. The Zing is constructed of wood and covered in aircraft fabric. The landing gear is conventional with sprung aluminum main gear and a steerable tailwheel. The double surfaced wing is strut-braced with two parallel main struts and jury struts per side.

The main gear sprung element has been moved from the half-axle to the rearward V strut and the early castoring nosewheel replaced with a steerable system with a simpler single leg. The fin of the T-10M is more angular and narrower than that of the T-10 and incorporates a triangular fillet. The T-10s are powered by 60 kW (80 hp) Jabiru 2200s, the T-10Ms by 74 kW (100 hp) Rotax 912S flat four engines.

Once the catheter is in and all preparations are complete elsewhere in the lab, the EP study begins. The X-ray machine will give the doctor a live view of the heart and the position of the electrodes. He will guide the (steerable) electrodes to the correct position inside the heart. The electrophysiologist begins by moving the electrodes along the conduction pathways and along the inner walls of the heart, measuring the electrical activity along the way.

The forward fuselage was metal-covered from the engine to the 158-liter fuselage-mounted fuel tank, after which the fuselage was fabric- covered. The fixed, divided type undercarriage had a main shock absorber leg, its upper end attached to a steel attachment near the mid-fuselage, allowing the wheel to remain nearly vertical during deflections, whilst providing a wide track. The wheels were connected to the lower fuselage with a swinging V-strut. A steerable tailwheel was used.

Because of the span difference, these leaned outwards at 45°, allowing them to carry ailerons on their trailing edges. In addition, it was claimed, these provided the lateral stability more usually secured with dihedral as well as producing additional lift. The fuselage and empennage of the AS-27 were conventional, with its cockpit over the lower wing. Its fixed conventional undercarriage had arched leaf spring cantilever main legs with cable bracing, together with a steerable tailwheel.

A mechanical arm similar to the Russian Lyappa arm used on the Mir space station will then move the module to a radial port of the CCM. Electrical power is provided by two steerable solar power arrays, which use photovoltaic cells to convert sunlight into electricity. Energy is stored to power the station when it passes into the Earth's shadow. Resupply ships will replenish fuel for LCM 1 for station- keeping, to counter the effects of atmospheric drag.

Santos-Dumont's "Number 6" rounding the Eiffel Tower in the process of winning the Deutsch de la Meurthe Prize, October 1901. Airships were originally called "dirigible balloons" and are still sometimes called dirigibles today. Work on developing a steerable (or dirigible) balloon continued sporadically throughout the 19th century. The first powered, controlled, sustained lighter-than-air flight is believed to have taken place in 1852 when Henri Giffard flew in France, with a steam engine driven craft.

Service is currently provided by a fleet of 26 Class N-5 cars that feature AC-induction propulsion, steerable axles, very large windows, comfortable seating, and are capable of . They were built by ABB Traction in 1992–1993 with their stainless steel bodies being built by SOREFAME which is a Portuguese Budd Company (Philadelphia) licensee. The last train ran on the Strafford Branch on March 23, 1956. Service is still provided on the Norristown High Speed Line today.

A 12-metre (40-foot) parabolic antenna was used to receive and transmit information to geostationary satellites, which served as the forerunners to modern telecommunication satellites. The steerable crossed yagi antenna was used to transmit and receive telemetry from various spacecraft of that era. The transmitters used Klystron power amplifiers, and the receivers were cryogenically cooled maser devices. Additional smaller VHF antennas were used to control the various functions of spacecraft and to send and receive information.

The tailskid was now steerable. Production Thunderbirds offered several other engines, all more powerful than the Curtiss. The least powerful was the Dayton Bear which originally powered an iceboat. The Bailey CR-7 Bull's Eye was a 7-ctlinder radial engine as was the Axelson (Floco) B. The elderly, heavy Hispano A water-cooled V-8 engine increased speeds by and the climb rate by 12% but needed a fuel tank to maintain the W-O-14's range.

It includes a redesigned and upgraded interior, Honeywell Primus Epic 2.0 avionics, a stern thruster, new Sumitomo corrosion-resistant landing gear, hydraulic electrically steerable nose gear, MT five-blade composite propellers and Pratt & Whitney Canada PT6A-135As. By November 2018, the Chinese shareholders invested €150 million ($172 million) to develop and produce the CD2, to construct a new facility in Wuxi and to expand its Oberpfaffenhofen base, for a 2021 service entry. It first flew on 28 March 2020.

Two-beam PDI provides a major advantage over other schemes by availing two independently steerable beams. Here, the test beam and reference beam are perpendicular to each other, where the intensity of reference can be regulated. Similarly, an arbitrary and stable phase shifts can be obtained relative to the test beam keeping the test part static. The scheme as shown in Figure 4 is easy to manufacture and provides user-friendly measuring conditions similar to Fizeau type interferometers.

The airframe of the 175 is all metal, constructed of aluminum alloy. The fuselage is a semi-monocoque structure, with exterior skin sheets riveted to formers and longerons. The strut-braced wings, likewise, are constructed of exterior skin sheets riveted to spars and ribs. The landing gear of the 175 is in a tricycle arrangement, with main gear legs made of spring steel, along with a steerable nosewheel connected through an oleo strut used for shock absorption.

The Commander Sport was designed to comply with the US Experimental - Amateur-built aircraft rules. It features a single main rotor, a single-seat open cockpit with a small cockpit fairing with a windshield, tricycle landing gear with a steerable nose wheel and wheel pants, plus a tail caster. The standard engine supplied was the twin cylinder, liquid-cooled, two-stroke, dual-ignition Rotax 582 engine in pusher configuration. The Rotax 503 and Rotax 447 engines were factory options.

Wright glider, coordinated turn using wing-warping and rudder, 1902. The Wrights solved both the control and power problems that confronted aeronautical pioneers. They invented roll control using wing warping and combined roll with simultaneous yaw control using a steerable rear rudder. Although wing-warping as a means of roll control was used only briefly during the early history of aviation, the innovation of combining roll and yaw control was a fundamental advance in flight control.

The High Court ruled that Hoover had deliberately copied a fundamental part of his patented designs in making its Triple Vortex bagless vacuum cleaner range. Hoover agreed to pay damages of £4 million. In 2005, Dyson incorporated the wheel ball from his Ballbarrow concept into a vacuum cleaner, creating the Dyson Ball. This ball, rather than the static wheels on existing vacuums, enabled it to become more steerable, which was more useful for navigating around obstacles and corners.

Manufacturers of this type of handcycle include Lighting Handcycles and Brike International Ltd. (Freedom Ryder). Another type of lean steer hand trike has two steering rear wheels and one non-steerable, powered front wheel with handholds offset at 180°, similar to pedal cranks, that can be operated with only one hand, thus making it easy to ride on an up-hill, and it can be ridden in a tighter curve with the automatic rear wheels steering system.

Millions of kites were sold and flying steerable kites became a craze in the mid-70's in the UK. The popularity of all types of multiple-line kite flying today can be attributed directly to Powell's development of a modern dual-line kite. Powell often took his kites around the country and sold them from the back of his car. In 1974 (approx) he was selling them on Paignton sea front. He advertised by simply flying the kites.

A C-train is a semi-trailer attached to a fifth-wheel on a C-dolly. Unlike in an A-Train, the C-dolly is connected to the tractor or another trailer in front of it with two drawbars, thus eliminating the drawbar connection as an articulation point. One of the axles on a C-dolly is self-steerable to prevent tire scrubbing. C-dollies are not permitted in Australia, due to the lack of articulation.

The main telescope at the observatory is the Lovell Telescope. Its diameter of makes it the third largest steerable radio telescope in the world. There are three other active telescopes at the observatory; the Mark II, and and 7 m diameter radio telescopes. Jodrell Bank Observatory is the base of the Multi-Element Radio Linked Interferometer Network (MERLIN), a National Facility run by the University of Manchester on behalf of the Science and Technology Facilities Council.

The missing lift is provided by lifting the nose and using engine power, or by angling the engine thrust. Some types also use steerable propellers or ducted fans. Operating in a state heavier than air avoids the need to dump ballast at lift-off and also avoids the need to lose costly helium lifting gas on landing (most of the Zeppelins achieved lift with very inexpensive hydrogen, which could be vented without concern to decrease altitude).

The 3D models were originally embedded as VRML objects and viewing required an appropriate plugin installed in the browser. In the new version of the website VRML models were replaced by X3D models, using the X3DOM library for viewing. Beside the interactively steerable/zoomable 3D model of each globe there is a background database with the most important information and a downloadable KMZ file for each globe, which can be opened in Google Earth as a new layer.

Between 1984 and 1989 she was member of the Committee on Energy, Research and Technology. And for the largest part of her time in Parliament she was also part of the Delegation for relations with Japan. During her time as MEP Viehoff was supportive of biotechnology as a socially steerable technology. In February 1987 she presented the report Biotechnology in Europe and the need for an integrated policy, the report was adopted by the European Parliament.

Bulk soil from the Moon or asteroids has a very low water content, and when melted to form glassy materials is very durable. These simple, glassy solids can be used for the assembly of habitats on the surface of the Moon or elsewhere. The solar energy can be concentrated in the manufacturing area using an array of steerable mirrors. The availability and favorable physical properties of metals will make them a major component of space manufacturing.

The telescope is fully steerable. The telescope sits on a reinforced concrete base, carved into bedrock, with a continuously-welded track sitting on a diameter outer ring, connected to the foundations with 260 pairs of anchor bolts, and supporting 16 wheels. In the centre is the azimuth bearing support, as well as the cable wrap and encoder system. The welded steel alidade then supports the elevation wheel, which is in turn connected to the primary mirror backing structure.

The rear decking starts behind the cockpit at the height of the pilot's head, gradually falling to the tail. The fin is strongly straight tapered and square tipped, with a straight edged rudder that extends down to the keel; the tailplane is both strut and wire braced to the fin. The Bal-Aire has a fixed, conventional undercarriage with faired legs and main wheels and a steerable tailwheel. The Bel-Aire first flew on 8 July 1960.

The Crossover has a fuselage-mounted tricycle undercarriage. All wheels are the same size and retract forwards; the mainwheels have brakes and the nosewheel is steerable. Power is supplied by two three-phase electric motors, each capable of providing for take-off and continuously, controlled together by a single throttle lever. These are mounted in the fuselage, with the four lithium batteries, storing a total energy of 36 kWh, just behind the cockpit at the centre of gravity.

In 1964, the University Grants Commission recognized the astronomy department and the observation facilities as Nizamia and Japal-Rangapur as Center for Advanced Studies in Astronomy (CASA). In order to observe the solar eclipse on February 16, 1980, CASA collaborated with Physical Research Laboratory and Space Applications Center in Ahmedabad to obtain a 10 feet steerable dish. This dish was used to make high resolution microwave brightness temperature measurements. It is since being used to study solar flux.

Image from Mars taken by the Viking 2 lander Communications were accomplished through a 20-watt S-band transmitter using two traveling-wave tubes. A two-axis steerable high-gain parabolic antenna was mounted on a boom near one edge of the lander base. An omnidirectional low-gain S-band antenna also extended from the base. Both these antennae allowed for communication directly with the Earth, permitting Viking 1 to continue to work long after both orbiters had failed.

A Quasi-Zenith satellite orbit Many objects in geosynchronous orbits have eccentric and/or inclined orbits. Eccentricity makes the orbit elliptical and appear to oscillate E-W in the sky from the viewpoint of a ground station, while inclination tilts the orbit compared to the equator and makes it appear to oscillate N-S from a groundstation. These effects combine to form an analemma (figure-8). Satellites in elliptical/eccentric orbits must be tracked by steerable ground stations.

Out of the Zenith, pp. 19–20 Once construction of the Lovell telescope was complete, the broadside array was put on a steerable mount and the pair were used as a tracking radio interferometer. This was then used to determine the 2D shape of quasars on the sky.Out of the Zenith, pp. 42–45. Rowson (1963) In the summer of 1961, a 25-foot (8-m) diameter paraboloid telescope was constructed (it was made of aluminium tubing and was mounted on the rotating structure of an old defence radar). This was then used as a steerable interferometer with the Mark I, with a resolution of 0.3 arcseconds, to determine the sizes of some high-redshift (z~0.86) quasars.Out of the Zenith, pp. 46–48 The Mark II telescope once constructed was also used as an interferometer with the Lovell telescope. This has a baseline of 425 m (1,394 ft) (meaning that it can synthesize a telescope with 425 m diameter), giving it a resolution of around 0.5 arcminutes.

Shane works at Boulder Nonlinear Systems, an organisation who are developing holographic optical trapping modules for the International Space Station. She is also working on low size, weight and power (SWaP) 3D wind sensor technologies for unmanned aerial vehicles. The optical trapping systems (tweezers) use focused laser beams to trap transparent microparticles, and the holographic optical trapping uses liquid crystal spatial light modulators that can convert a single beam into separate steerable beams. This system allows Shane to position trapped particles in arrays.

Bentov began with a workshop in the basement of a Catholic church in Belmont, Massachusetts in the 1960s. In 1967, he built the steerable heart catheter and attracted the attention of businessman John Abele, with whom Bentov founded the Medi-Tech corporation in 1969. Abele later recalled of Bentov's workshop, In 1979, Abele and Peter Nicholas looked to grow the successful business and established Boston Scientific as a holding company to purchase Medi-Tech. Bentov was the holder of numerous patents.

23 On entering service, two stern-mounted, short-length torpedo tubes for Mark 20 anti-submarine torpedoes were fitted. However, the development of steerable wire-guided torpedoes made the less-capable aft- firing torpedoes redundant; they were closed off, and later removed during a refit.Shaw, HMAS Onslow, p. 19 Orion was laid down by Scotts Shipbuilding and Engineering Company at Greenock, Scotland on 6 October 1972, launched on 16 September 1974, and commissioned into the RAN on 15 June 1977.

The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of . The aircraft has a standard empty weight of . The SR-1 Hornet features a strut-braced and cable-braced biplane layout, a single-seat open cockpit, fixed conventional landing gear with a steerable tail wheel, and a single engine in pusher configuration. The aircraft is made from bolted-together aluminum tubing, with its flying surfaces covered in doped aircraft fabric.

The tail unit was conventional, with a flight-adjustable tailplane mounted on top of the fuselage and braced from below with a single strut on each side. Both it and the fin had straight leading edges which led to rounded tips. Both rudder and elevators were unbalanced; the rudder was rounded and extended to the keel, operating in a notch between the elevators. On the fuselage underside below the tail was a rubber sprung, steel and dural tailskid with a steerable shoe.

The first curtain array to achieve popularity was the Sterba curtain, patented by Ernest J. Sterba in 1929 and this was used by Bell Labs and others during the 1930s and 1940s. The Sterba curtain is however a narrowband design and is only steerable by mechanical means. Antenna G1 at Hörby shortwave station, which was operated by Radio Sweden but was shut down in 2011. It consisted of 16 horizontal wire dipoles in a 4x4 array, suspended in front of a wire screen.

22 Both tracks and wheels were used for steering. The steering system was set up so that gentle turns used just the steerable front wheels, but brakes would be applied to the tracks the farther the steering wheel was turned. The drive sprocket had the track-saving but more complicated rollers rather than the more common teeth. The rear suspension consisted of five double roadwheels, overlapping and interleaved in the Schachtellaufwerk layout, mounted on swing arms sprung by torsion bars.

Until 2010, the main building, Granada House, had a red neon "Granada TV" sign on the roof, which was a landmark for rail passengers travelling from the west into Manchester city centre. A decorative broadcasting tower was erected at the behest of Sidney Bernstein to give the studios an embellished and professional appearance. At its top, this tower had an enclosed, steerable, microwave dish which, pre-satellite, provided line of sight outside broadcast links to the company's 'Eagle Tower' vehicles.

The next project of Jacques Charles and the Robert brothers was La Caroline, an elongated steerable craft that followed Jean Baptiste Meusnier's proposals for a dirigible balloon, incorporating internal ballonnets (air cells), a rudder and a method of propulsion. On September 19, 1784 the brothers and M. Collin-Hullin flew for 6 hours 40 minutes, covering 186 km from Paris to Beuvry near Béthune. This was the first flight over 100 km. Gas balloons remained popular throughout the age before powered flight.

It was possible to use steerable landing gear legs for this, but only at the cost of added complexity. An easier solution was to simply use a straight wing so the landing gear were in a line. However, this would limit the design to slower speeds below about Mach 0.7 (see wave drag). This was perfectly acceptable for short-haul role, where the cruise times were so short that added speed would have little actual effect on round-trip times.

Amongst the main requirements are the need for separate passenger and driver compartments, high internal headroom, a ramp for wheelchair user access and the ability to turn through 180° on either lock between two walls apart to minimise the impact of the many taxis operating in the city on other road users. Two production vehicle models comply with the current conditions: the London Taxi Company TX4 and a specially-modified taxi variant of the Mercedes-Benz Vito with steerable rear wheels.

Construction was begun in 2007 and completed July 2016 and the telescope became operational September 25, 2016. The world's second largest filled-aperture telescope is the Arecibo radio telescope located in Arecibo, Puerto Rico. Another stationary dish telescope like FAST, whose dish is built into a natural depression in the landscape, the antenna is steerable within an angle of about 20° of the zenith by moving the suspended feed antenna, using a 270-meter diameter portion of the dish for any individual observation.

Der Luftpirat und sein lenkbares Luftschiff (The Air Pirate and His Steerable Airship) was a German pulp magazine with 165 issues from 1908–1911. The book followed the adventures of Captain Mors, the "Air Pirate". The series was banned in 1916 together with nearly 150 other series under the military censorship apparatus. In the case of the "Luftpirat" and some other series, the production plates were destroyed so the series couldn't be reprinted after the end of the First World War.

The linkage for the feedback system was for used front towing, and was disengaged during rear towing. The towing arm could be fitted to the front truck, or the steerable rear axle of the rear bogie. The towing arm was fitted with a sprung force stem, contrived so that the tow arm 'floated' horizontally at zero relative weight. Each front corner of the chassis was fitted with a swing-out A-frame boom equipped with a screw jack and foot plate.

The aircraft is fitted with a retractable tricycle undercarriage with steerable nosewheels, allowing a fairly large crab angle during cross-wind landing. The reverse pitch control with which the aircraft is fitted allows the constant-speed mechanism to be manually overridden to reverse the blade pitch angle, thus providing excellent ground-handling characteristics, helping to slow down the plane to shorten the landing run. This control also allows the aircraft to back up on its own during taxiing.Latham (1982), p.

Radio and submillimeter telescopes use much larger dishes or antennae, which do not have to be made as precisely as the mirrors used in optical telescopes. The Arecibo Observatory uses a 305 m dish, which is the world largest single-dish radio telescope fixed to the ground. The Green Bank Telescope has the world's largest steerable single radio dish with 100 m in diameter. There are larger radio arrays, composed of multiple dishes which have better image resolution but less sensitivity.

Its span wing has an area of and is supported by "V" struts and jury struts. The standard engine recommended is the Rotax 912UL four-stroke powerplant. The World Directory of Leisure Aviation 2011-12 states that landing gear uses sprung aluminium suspension for all three wheels and that the nose wheel is freely castering and steering is accomplished with differential braking. Later models have sprung aluminium suspension for the main wheels and a rudder pedal-controlled steerable nose wheel.

The trailer is also different, as is the configuration of the winches and boxes. Similar to the Elefant, the SLT56 is equipped with two Rotzler winches for pulling tanks or other disabled vehicles onto the trailer. The trailer's platform measures 8.9m by 3.15m, the weight is distributed on 24 wheels, two per short axle, six of those axles per side (the front two are steerable). In 1993 the SLT56 was modified due to the experiences while deployed with the UN in Somalia.

Under it, at the extreme fuselage was a steerable tailwheel. It was powered by an air-cooled 225 hp (168 kW) Continental E225 flat-six engine mounted well forward and low in the nose. This initially drove a fixed pitch, two blade propeller though there were plans to replace it with a variable pitch one. The Ag-1 was followed by two more agricultural prototypes, the Transland Ag-2 and Transland Ag-3; the latter was the immediate predecessor of the Piper Pawnee.

VERITAS is constructed of four 12 m diameter Imaging Atmospheric Cherenkov Telescopes with an approximate separation of 100 meters (330 feet) between each adjacent telescope. Each telescope comprises a large, steerable optical reflector and a high-speed photomultiplier tube camera. Multiple telescopes in an array are needed for stereoscopic observations of the Cherenkov light produced in extensive air showers. These stereoscopic observations allow precise reconstruction of the particle shower geometry, thus giving greatly improved angular and energy resolution compared to a single telescope.

Spirit of America was the first of the modern record breaking jet-propelled cars, built with a narrow streamlined fuselage, three-wheel chassis, and, most significantly, turbojet engine. Like most of the other competing vehicles, the engine was ex- military. The first Spirit had a General Electric J47 engine from an F-86 and was tested at Bonneville Salt Flats in 1962, where difficult handling resulted in failure. Before trying again, a new stabilizer and steerable front wheel were added.

In 1940, two United States Forest Service Smokejumpers, Earl Cooley and Rufus Robinson, showed that parachutists could be placed very accurately onto the ground using the newly invented 'steerable parachute'. These parachutes, and the techniques smokejumpers used with them, were completely different from those used by Army airborne units. It was in that year that Dr. (Captain) Leo P. Martin was trained by the U.S. Forest Service Smokejumper Parachute Training Center in Seeley Lake, Montana as the first 'para-doctor'.

By the end of 2010, nearly 100 Sensei systems have been shipped worldwide since its 2007 release. The system has been used to perform almost 5,000 procedures. The Sensei system operates by guiding standard catheters through a manipulated robotically steerable sheath (hollow tube) in the patient's vasculature. The doctor performs the procedure at a control station with a technology called "IntelliSense" to proximally measure the forces applied along the shaft of the catheter as a result of catheter tissue contact.

LZ 129 Hindenburg at Lakehurst Naval Air Station, 1936 The modern age of aviation began with the first untethered human lighter-than-air flight on November 21, 1783, of a hot air balloon designed by the Montgolfier brothers. The practicality of balloons was limited because they could only travel downwind. It was immediately recognized that a steerable, or dirigible, balloon was required. Jean-Pierre Blanchard flew the first human-powered dirigible in 1784 and crossed the English Channel in one in 1785.

To maintain speed, the engines were upgraded to four models, which were fitted with four diameter steerable Dowty Rotol propellers. The work cost around £5 million for each craft, and they were designated Mark IIIs; the improvements allowed them to operate in seas up to high and with winds.Paine and Syms 2012, pp. 595-596. The stretched SR.N4s (Super-4's) was the world's largest hovercraft, and continued to be until the Russian Zubr class LCAC hovercrafts' arrival early in the 21st century.

The aircraft is of typical motorglider configuration, with a tractor propeller and long, tapering wings. As originally designed, it also had a sailplane-like undercarriage consisting of a single mainwheel and a steerable tailwheel; however, later versions have a fixed taildragger undercarriage with two spatted mainwheels. The pilot and passenger sit side by side. With numerous design changes - including modern Rotax engines, state-of-the-art avionics, and aerotow capabilities, it is still in production by the M&D; Flugzeugbau company in Germany.
|
|
The tail surfaces were also all-metal and straight-tapered; the horizontal surfaces were mounted on top of the fuselage. The fuselage was a standard all- metal semi-monocoque, with the side-by-side seats under a long, low rearward- sliding two-piece canopy, with its rear at the wing leading edge. The Albatross's undercarriage had two main wheels side by side, attached to the fuselage and retracting forward into it. Its tail wheel was steerable via the rudder bar.
|
|
The main landing gear retracted inward into the wings, telescoping nine inches to clear the underside of the fuselage, and the steerable tailwheel was fully retractable. With a loaded weight of 12,086 lb, the XP-47B was almost twice as heavy as its competitors. Performance was higher than expected with a maximum speed of 412 mph. The XP-47B crashed on August 8, 1942, however, an order for 773 production aircraft had been placed almost two years before on September 13, 1940.
|
|
A raised roof line continued from the engine housing forward, providing space above the wing for three windows on each side for the observer and a more conventional, framed cockpit above and forward of the wing. The lower fuselage was modified by a fixed, tricycle undercarriage with closely spaced, trousered main legs, rubber-sprung mainwheels with low pressure tyres, a shrouded, steerable nosewheel and a little tailwheel. As a result the empty weight increased by compared with the glider. The wing remained unchanged.
|

The Pützer Elster "Magpie" was developed from the Motorraab motor glider which had itself been developed from the Doppelraab glider. The Elster was the first aircraft produced in Germany after World War II in any significant numbers. The design shared the wing of the Doppelraab, braced by metal struts, but was given a new monocoque fuselage constructed of plywood with seats for two occupants arranged side by side. The tricycle landing gear unusually featured a steerable nosewheel controlled by a hand grip.

Runabouts can be powered by inboard engines, outboards, jet drives, or inboard-outboard (I/O) drives. Engines can be gasoline or diesel systems. Inboards have the engine block permanently mounted within the hull of the boat, with a drive shaft and a propeller to drive the craft underneath the hull, and a separate rudder to steer the craft. Outboards are steerable external drive motors containing the engine block, linkage gears, and propeller within a single unit, taking the place of a rudder.

Wind powered vehicles for recreational purposes Wind powered vehicles are well-known since long time. They can be realized with sails similar to that used on ships, by using an onboard wind turbine, which drives directly the wheels or which generates electricity for electric engines driving the wheels or can be pulled by a kite. Wind powered land vehicles need an enormous clearance in height, especially when sails or kites are used and are unsuitable in urban area. They may be also be bad steerable.

Similar devices are now extensively used in large, steerable rockets and in space vehicles. Another improvement was that initially the alcohol tank, and later the LOX tank also, were built integral with the outer skin, saving weight. The structure was also largely aluminum, as opposed to steel used in the V-2, thus shedding more weight. Vikings 1 through 7 were slightly longer (about 15 m, 49 ft) than the V-2, but with a straight cylindrical body only in diameter, making the rocket quite slender.

Privateer P-1 Privateer P-2 Privateer P-3 The two seat sportsplane's fuselage had two distinct parts, a forward boat hull containing the cockpit and mounting wings, engine and the land undercarriage on amphibious versions and a rear part bearing the tail. The hull had ash longerons with spruce stringers and was Alclad skinned. It was flat-bottomed with a single step under the wing, ending abruptly about halfway between the trailing edge and tail. At its rear it carried a steerable tailwheel/water rudder.

The front axle of the model is mounted on a central pivot with a simple copper stub spring, which provides a crude form of suspension. It is also steerable, by means of a shaft running from the axle up inside the chimney (later models post 67). Early models did not use the later control rod for steering but used a rod mounted directly into a hole in the early model square axle box. Both designs could be screwed down to lock the wheels in a fixed position.

It also housed an steerable radio telescope once used in Project BETA, a search for extraterrestrial intelligence. A 41-cm (16-inch) Boller and Chivens Cassegrain reflector originally housed at Oak Ridge is available for public use at the National Air and Space Museum's Public Observatory Project on the National Mall in Washington, DC.NASM AirSpace Blog, March 29, 2009. and NASM Public Observatory Project The inner main-belt asteroid 4733 ORO, discovered at Oak Ridge in 1982, was named in honor of the observatory.

Tank steering systems allow a tank, or other continuous track vehicle, to turn. Because the tracks cannot be angled relative to the hull (in any operational design), steering must be accomplished by speeding one track up, slowing the other down (or reversing it), or a combination of both. The half- tracks avoid this by combining steerable wheels and fixed-speed tracks. Early steering systems were adopted from tracked work vehicles, generally using a clutch to reduce power to one track, causing it to slow down.

With double the mirror diameter of the original WFIRST design, it allows for up to twice the image resolution and gathers four times the light. Unlike civilian telescopes, the NRO instrument also has a steerable secondary mirror for additional precision. The telescope has a much wider field of view than Hubble due to its shorter focal length, allowing it to observe about 100 times the area at any given time as Hubble can. This has led to the donated telescopes' characterization as "Stubby Hubbles".

Steerable Rogallo kites usually have a pair of bridles setting a fixed pitch, and use two strings, one on each side of the kite, to change the roll. Rogallo also developed a series of soft foil designs in the 1960s which have been modified for traction kiting. These are double keel designs with conic wings and a multiple attachment bridle which can be used with either dual line or quad line controls. They have excellent pull, but suffer from a smaller window than more modern traction designs.

The dishes were welded onto the hulls of two diesel submarines and laid down onto railway bridge trusses. The ADU-1000 antennas were mounted onto steerable frames constructed from battleship gun turrets and railway bridge trusses. The Pluton complex supported all the Soviet space programs until 1978, when the Yevpatoria RT-70 radio telescope was built, then the Pluton became a backup system for the RT-70. The Pluton complex was the world's highest capacity deep space communication system prior to Goldstone in 1966.

The rounded nose and the cabin were plywood skinned and the rest fabric covered. The spatted mainwheels were mounted on short cantilever struts, making only a shallow angle to the ground and with the shock absorbers inside the fuselage. On the original aircraft there was a small castorable tailwheel, but later this was supplanted by a spatted, steerable nose wheel with a faired leg.E-210 with tricycle undercarriage By mid-1937 the original single fin had been replaced by a twin endplate fin arrangement.

During the latter part of the 18th century, there were numerous attempts to produce self-propelled steerable vehicles. Many remained in the form of models. Progress was dogged by many problems inherent to road vehicles in general, such as adequate road surfaces, suitable power plant giving steady rotative motion, tyres, vibration resistant bodywork, braking, suspension and steering among other issues. The extreme complexity of these issues can be said to have hampered progress over more than a hundred years, as much as hostile legislation.

The design features a forward fuselage of welded 4130 steel tubing, mated to an aluminum tailboom. The horizontal stabilizer, tail fin and wings are also constructed of riveted aluminum tubing with all flying surfaces covered in doped aircraft fabric. The Ultrastar introduced the trademark folding wings and tail that became a feature of future Kolb designs. Like the Flyer, the Ultrastar's conventional landing gear consists of sprung steel tubing for the main gear but replaced the Flyer's sprung tail skid with a steerable sprung tail wheel instead.

Most other propeller-driven ships will reverse the direction the prop spins. For a paddle wheel ship, reversing the direction of the paddle will provide astern propulsion. Redirecting the thrust of a water jet driven craft, changing the cyclic pitch of a Voith-Schneider propulsor, or rotating an azimuth thruster 180 degrees has the same effect. As the efficiency of traditional rudders is greatly reduced when not located in the propeller wash, only propulsion systems with steerable thrust provide adequate maneuverability during astern operation.

The carriage was a large box-trail design with four non-steerable wheels. The wheels were fitted with detachable grousers designed by major Crispino Bonagente for traction on soft ground and was towed in one piece by a Pavesi- Tolotti artillery tractor. When not on the move the grousers were removed and the steel wheels rode on an inclined set of steel rails when in firing position. The steel rails were mounted on a firing platform made of wooden beams which allowed the gun 360°of traverse.
|
|
The vehicles also have steerable trucks that can navigate sharp curves and steep grades, as well as align precisely with the platform doors at the stations. The cars can run at up to , and they can operate on trackage with a minimum railway curve radius of . Each car is long and wide, which is similar to the dimensions of rolling stock used on the New York City Subway's B Division. Trains can run in either direction and can consist of between one and four cars.

Farley 1991, p. 22. Early on, IAI decided to adopt a delta wing configuration, of which the company was already familiar with through its work on the earlier Kfir, which was paired with large, steerable canards situated forward of the wing. The delta wing arrangement was relatively low-weight, provided space for considerable fuel capacity, a smooth low-altitude fight attitude, and high levels of directional stability while flown at high angles of attack (AOA). The canard generated additional lift and positive control when at high AOAs.

The Camera Optics Module of KH-7 consists of three cameras: a single strip camera, a stellar camera, and an index camera. In the strip camera the ground image is reflected by a steerable flat mirror to a diameter stationary concave primary mirror. The primary mirror reflects the light through an opening in the flat mirror and through a Ross corrector. It took images of a 6.3 degree wide ground swath by exposing a wide moving portion of film through a small slit aperture.

GRAD was another technology demonstration program to test the suitability of bismuth germanate in gamma-ray detectors, the suitability of n-type, high-purity germanium gamma-ray detectors for space, the performance of an advanced gamma-ray spectrometer and to study the gamma ray background around the shuttle, as well as the gamma-ray spectrum of the sun and the Galactic Center. The instrument is non-steerable and is pointed by moving the Shuttle. Dr. C. Rester from the University of Florida was the PI.

The Lambada was designed to comply with the Fédération Aéronautique Internationale microlight rules at a gross weight of and US light-sport aircraft rules at . The design is on the Federal Aviation Administration's list of approved special light-sport aircraft. The aircraft features a cantilever wing, a T-tail, a two-seat side-by-side enclosed cockpit under a bubble canopy, fixed tricycle or conventional landing gear with a steerable tail wheel and a single engine in tractor configuration. The aircraft is made from composites.

Quite an exception in that era were tractors which obtained four tires of the same size, represented by the Super Trac series. The Profi Trac series were equipped with four equally sized tires, mounted on two steerable axles instead of just one. The rear axle of the Profi Trac could steer in the opposite or same direction as the front axle, as well as not steering at all. In 1978, a unique specimen was built, the so-called Profi Trac 5000 TVL with 500 hp.

The steerable front foil featured two anhedral sections and two dihedral sections with a strut down the middle, resulting in a diamond shape. The ship's helmsman had to be qualified as both a sea pilot and an aircraft pilot. Bras d'Or had two propulsion systems: one for foilborne operation and one for hullborne operation, which included four engines. Foilborne power was provided by a FT4A-2 gas turbine developing at 21,500 rpm through General Electric gearboxes to a pair of three-bladed supercavitating propellers.

The span of both the canard and main wing were increased to improve lifting ability. These reduced stall speed and shortened takeoff and landing distances; its attitude on the ground was also adjusted for optimal takeoff and landing.The Canard Pusher N°16 Originally designed with a fixed fin and only the faired tailwheel acting as the rudder, a conventional rudder was substituted. The steerable tailwheel allows directional control up to the point of liftoff, as the Quickie does not lift its tail during the takeoff run.

Eutelsat 16C (formerly SESAT 1) is a satellite operated by Eutelsat, originally the first of a series of SESAT (Siberia - Europe SATellite) satellites. It provides a wide range of telecommunications services over a very large geographical coverage area that extends from the Atlantic Ocean to Eastern Russia, including a large part of Siberia. The satellites also provide broadcasting services to Africa by means of steerable spotbeams. On 29 January 2010, the satellite moved to 16° E to take over some services from the malfunctioning W2 satellite.

Sleds with a greater surface area (anything but runner sleds) are able to make the first runs a great deal easier than the variety of sleds with metal runners. Runner sleds are typically faster once the snow has compacted or turned icy. In the 1880s, Samuel Leeds Allen invented the first steerable runner sled, the Flexible Flyer. Since that date, the ability to steer the sled away from obstacles has led people to believe it to be more appropriate choice for the safety conscious.

The wings and horizontal tail are quick-folding for storage and ground transport. The original Mark III can be made ready to fly from trailering in eight minutes by one person without the use of tools, while the newer M3X variant is rated at 15 minutes to assemble for flight. The landing gear is sprung tubing for the main gear, with a steerable sprung tailwheel and the cabin is in width. Factory options include brakes, Ballistic Recovery Systems airframe parachute and powder coating of the steel parts.

The steerable nosewheel had the same diameter as the main wheels. The first prototype, registered PH-ALB, first flew in November 1935.Bernard Klein collection In all, six were built over the next two years but despite good reviews the hoped for sales did not happen. de Schelte sold licence build rights in the UK to Aircraft Constructions Ltd of Sidcup, but demonstrator PH-AM was lost in a crash whilst demonstrating at Gravesend at the start of a sales tour in March 1937.

After removing and inverting the detachable slot-car pin, the cars could also be run on the floor, with the front wheels steerable into one of three set positions (left, center, right), held by small detents on the reverse side of the pin. Although some playsets were marketed to feature competitive play between two operators ("Racerific"), in truth there was little allowance for competition since there was no operator control over speed. Motorific vehicles and accessories remain popular as collectibles, particularly with baby boomer toy aficionados.

The facility built diamond core heads and drilling bits and soon began producing stabilizers, drilling jars and other equipment. In 1977, the Celle engineering and manufacturing team introduced the Navi-Drill line of downhole drilling motors, which has led the drilling industry in performance and reliability for three decades. Other innovations developed in Celle include the industry's first steerable motor system, and the AutoTrak Rotary Closed Loop System. In 1978, Christensen Diamond Products was acquired by Norton Co. and its name changed to Norton Christensen.

According to the manufacturer, the torpedo reaches a speed of over 400 km/h underwater and is steerable. It is not dependent on the launch of submarines, but can dive into the water from air and continue its supercavitation trip there. There is no known defence against such a torpedo and it would therefore be an effective short-range weapon against heavily protected and mobile military sea targets. The system would also be able to combat other unguided supercavitation torpedoes due to its high maneuverability.

During 1984–96, he conceived and directed the design and construction of the Giant Metrewave Radio Telescope (GMRT), consisting of 30 fully steerable parabolic dishes of 45m diameter that are located in a Y-shape array of about 25 km in extent in Western India. A novel concept developed by him made it possible to construct such large antennas very economically. GMRT is a highly versatile instrument. It is the world's largest radio telescope operating in the frequency range of about 130–1430 MHz.

On 30 March 2017, the launch from Pad 39A, Kennedy Space Center, Cape Canaveral, Florida, became the first to reuse an orbital rocket's first stage, booster B1021, previously launched on the 23rd Falcon 9 mission that launched CRS-8. After delivering the payload, the first stage landed on a drone ship, becoming the first orbital rocket stage to return from space for the second time. Additionally, one clamshell half of the payload fairing remained intact after a successful splashdown achieved with thrusters and a steerable parachute.

The crane is mobile with four groups of steerable wheels, one on each corner. Boats are typically lifted using straps, slung between the two sides which can be passed under boats when either in the water or on the hard stand. Steel wires on pulleys are used to lift the boat. To remove a boat from the water, the boat is positioned in a narrow dock, or lifting well with two paths along each side, which are at the same level as the hard stand.

The Malloy Hoverbike is a single-seater turbo-fan powered, vertical take-off and landing (VTOL) quadrocopter developed in 2006 by New Zealand inventor Chris Malloy. The Hoverbike has two forward and two aft-mounted vertical propellers each enclosed in a hoop nacelle. The nacelles feature steerable blades beneath which control the direction of flight. Each propellor pair has partial overlap and when not in use they can be folded over each other to further reduce the parking footprint and make packing and transportation easier.

The plasma pressure stretches the magnetic field and inflates a bubble of plasma around the spacecraft. The plasma then generates a kind of miniaturized magnetosphere around the spacecraft, analogous to the magnetosphere that surrounds the Earth. The protons and electrons which make up the solar wind are deflected by this magnetosphere and the reaction accelerates the spacecraft. The thrust of the M2P2 device would be steerable to some extent, potentially allowing the spacecraft to 'tack' into the solar wind and allowing efficient changes of orbit.

Two 8 hp (6 kW) West Bend 82 go-kart engines were mounted behind the fairing on short struts, driving pusher propellers. Fin and rudder were straight tapered and square topped, with the latter extending down to the keel. The constant chord, square tipped tailplane was mounted on top of the fuselage and carried separated elevators, cut away inboard to permit rudder movement. The landing gear comprised a monowheel, fixed but partially faired, a steerable tailwheel and two small balancing outrigger wheels on short, faired struts below the interplane struts.

After the war very large parabolic dishes were built as radio telescopes. The 100 meter Green Bank Radio Telescope at Green Bank, West Virginia, the first version of which was completed in 1962, is currently the world's largest fully steerable parabolic dish. During the 1960s dish antennas became widely used in terrestrial microwave relay communication networks, which carried telephone calls and television programs across continents. The first parabolic antenna used for satellite communications was constructed in 1962 at Goonhilly in Cornwall, England to communicate with the Telstar satellite.

By controlling their relative power with regard to an external stimulus such as light, a robot with simple behaviours such as light-seeking or light avoidance, may be constructed. This idea of creating a controllable, steerable BristleBot can be further extended by using a WiFi enabled micro controller to create a bristlebot that you can drive from a smartphone, or even teach to drive autonomously. In BEAM robotics, a sophisticated bristlebot may begin to resemble a Walker, although these multi-legged robots are usually much more sophisticated, using multiple actuators with independent control.

A rectangular air intake ramp and a Splitter plate (only on J-10A) are located underneath the fuselage, providing the air supply to the engine. Newer variants use a diverterless intake that does not require a splitter plate, and may reduce radar cross signature. Also under the fuselage and wings are 11 hardpoints, used for carrying various types of weaponry and drop-tanks containing extra fuel. The retractable undercarriage comprises a steerable pair of nose-wheels underneath the air intake and two main gear wheels towards the rear of the fuselage.

Beginning in the 1870s, some Englishmen adapted a type of delivery sled for daring dashes down twisting narrow streets of St. Moritz. Subsequently, other tourists wanted a Victorian ride, and larger steerable devices were contrived: the early luge/skeleton individual sleds, and the bobsleigh (or bobsled). Careening around the town's streets became increasingly popular, but the incidence and frequency of pedestrian collisions and risk to life grew proportionately. Therefore, Badrutt stepped in and created the first purpose-built half-pipe track, now familiar from the Winter Olympic Games.

Each vessel in the series is long and wide with a draft forward (bow) of . Each tug has a capacity of 10 tonnes bollard pull at 85 per cent maximum continuous rating (MCR), speed of 12 knots at 85 per cent MCR and is fitted with two Caterpillar Kirloskar engines, coupled to two steerable rudder propellers of diameter. The vessels have two auxiliary electrical generation plant of 60 kW each and are fitted with a sewage treatment plant. They have been designed by M/s Ska Marine, Chennai.

The following three were built with the same basic hull, but steerable prop pods. The oldest of the second generation boats is named "Gibb Gilchrist", followed by the "Robert C. Lanier", "Dewitt C. Greer", "Ray Stoker, Jr.", and the "Robert H. Dedman". The later 4 vessels are all painted in a differing color scheme to honor various universities of the State. Consecutively as named above starting with the Lanier, these schemes are Orange/White for UT, Maroon/White for TAMU, Green/Gold for Baylor U., and Red/Blue for Southern Methodist U.

A Holt artillery tractor in use by the French Army in the Vosges during the spring of 1915. In England, starting in 1905, David Roberts of Richard Hornsby & Sons had attempted to interest British military officials in a tracked vehicle, but failed. Holt bought the patents related to the "chain track" track-type tractor from Richard Hornsby & Sons in 1912 for £4,000 (almost £400,000 at 2012 value). Unlike the Holt tractor, which had a steerable tiller wheel in front of the tracks, the Hornsby crawler was steered by controlling power to each track.

Airmanship 490 (AM-490) is the basic free fall course instructed by members of the Wings of Blue. Students enrolled in the course undergo more than 30 hours of ground training prior to their first free fall jump. The rigorous ground training introduces and develops procedures and techniques for high altitude free fall, and for operating a steerable parachute system. The course focuses on safety and emergency procedures to aid the students' ability to overcome their fears and perform under the extremely stressful and potentially life-threatening situations they may encounter.

Two lighter chains were led down from the wheelhouse and attached to the heavy chain and also to the ship's frames. This allowed some limited movement of the rudder, and the ship became steerable again. On the morning of Sunday 15 September the storm finally abated. Towle and the passengers committee insisted that the Captain try the repaired rudder and eventually the engines were started and at 5 pm that day after 75 hours of drifting out of control the ship answered the helm and was turned on to a course towards Ireland, away.

On each side a forward leaning bracing strut runs from the lower rear cabin to the front wing spar. The Sländan has a short, fixed, tricycle undercarriage with a steerable nosewheel; the mainwheels, fitted with brakes, are mounted on straight steel cantilever legs from the lower fuselage. There is a protective tailskid on the tip of the underfin. The prototype Sländan was initially powered by a (21 kW) (28 hp) König SD 570 4-cylinder two-stroke engine though there were plans to replace this with a Lotus Magnum 2.25 when this type became available.

He gave the Royal Institution Christmas Lectures in 1954 on The Story of Petroleum. Turbine drilling is best used for drilling hard rocks at high bit RPMs with diamond impregnated bits, and can be used with an angled drive shaft for directional drilling and horizontal drilling. It competes though with moyno motors and increasingly with rotary steerable systems and is again out of favour. Whittle left Shell in 1957 to work for Bristol Aero Engines who picked up the project in 1961, setting up "Bristol Siddeley Whittle Tools" to further develop the concept.

Additionally, an uncommon Champ variant—the 7HC—was produced with an enlarged rear seat allowing 2 passengers to be carried. The landing gear of most Champs is in a conventional arrangement, though two variants with tricycle gear were produced, and a model with reversed tricycle gear was tried. Conventional-gear Champs feature a steerable tailwheel and most have steel tube main gear which use an oleo strut for shock absorption. One variant utilized sprung-steel main gear, and American Champion uses aluminum gear legs in its production model of the Champ.

The next project of Jacques Charles and the brothers was to build an elongated, steerable craft that followed Jean Baptiste Meusnier's proposals (1783–85) for a dirigible balloon. The design incorporated Meusnier's internal ballonnet (air cells), a rudder, and an ineffective parasol-paddle based method of propulsion. On 15 July 1784 the brothers flew for 45 minutes from Saint-Cloud to Meudon with M. Collin-Hullin and Louis Philippe II, the Duke of Chartres in their elongated balloon. It was fitted with oars for propulsion and direction, but they proved useless.

The bubble canopy tips up for access and has a built-in vent. The landing gear consists of a retractable main monowheel gear, a fixed (or optionally steerable) tail wheel and faired polymer wing tip wheels. The electric motor is powered by two lithium polymer battery packs mounted near the aircraft's center of gravity, totalling a capacity of 4.3 kWh and weighing 15.5 kg (34.2 lbs). The nose-mounted propeller folds alongside the aircraft's nose when not powered to reduce drag and self-deploys when power is applied.

Green Bank is located within the National Radio Quiet Zone, which means that radio transmissions are heavily restricted by law. This policy is enforced by a "radio policeman" who uses specialized equipment to detect signals from unauthorized electronics. Green Bank is home to the Green Bank Telescope, the world's largest fully steerable radio telescope, which was operated by the National Radio Astronomy Observatory (NRAO) until September 30, 2016. Since October 1, 2016, the Telescope has been operated by the Green Bank Observatory, which is no longer part of the NRAO.

A switchable array of feed antennas in the focal plane is referred to as a switchable FPA. With this configuration, it is possible to switch between a set of beams directed in different directions. This makes the system steerable in the switching sense, thus creating a multi-beam system. In a switched FPA, the distance between feeding elements are chosen following : \Delta d = F \lambda/D, where F is the focal length of the optical system, D is the diameter of the optical system and λ is the wavelength.

Modern submarines have multiple passive hydrophone systems, such as a steerable array in a bow dome, fixed sensors along the sides of the submarines, and towed arrays. They also have specialized acoustic receivers, analogous to radar warning receivers, to alert the crew to the use of active sonar against their submarine. US submarines made extensive clandestine patrols to measure the signatures of Soviet submarines and surface vessels. This acoustic MASINT mission included both routine patrols of attack submarines, and submarines sent to capture the signature of a specific vessel.

He hires Lomax (Kirk Douglas) to assist him, even though Lomax had worked as a hired gun for Pierce and was instrumental in sending Jackson to prison. Jackson needs Lomax not only because of his marksmanship, but also because he is a safecracker. The gold shipment is being transported in a "war wagon", a heavily armored stagecoach armed with a deadly Gatling gun in a top-mounted steerable turret. Jackson and Lomax assemble a gang and plan to rob the war wagon at the weakest point in the route it travels.

An officer programs a JPADS bundle with drop coordinates in preparation for a resupply mission The steerable parachute or parafoil is called a "decelerator," and gives the JPADS system directional control throughout its descent by means of decelerator steering lines attached to the Autonomous Guidance Unit (AGU). They create drag on either side of the decelerator, which turns the parachute, thus achieving directional control. The AGU contains a GPS, a battery pack, and the guidance, navigation and control (GN&C;) software package. It also houses the hardware required to operate the steering lines.

Kiceniuk abandoned the designs for Icarus III and Icarus IV in favor of a monoplane configuration for Icarus V. Icarus V was a swept wing, constant-chord, flying wing monoplane with a span. Construction was of cable- braced aluminum tubing covered with fabric. The leading edge had foam sheet formed over aluminum ribs. It had an efficient high-lift airfoil giving it a glide ratio of 10:1, which was remarkable for a hang glider (Rogallo wings were hardly more than steerable parachutes with glide ratios of around 3:1).

The SES-6 satellite replaces the aging NSS-806 (launched on 28 February 1998 as Intelsat 806). It is nearly twice as large as NSS-806, with two C-band beams and has a total of five steerable Ku-band beams, including four beams for the Americas and one beam covering the Atlantic Ocean region. The C-band beams cover the East Atlantic (Europe, North Africa) and West Atlantic (United States, Mexico, South America). The Ku-band beams cover East Atlantic (Europe, Iceland, Greenland), West Atlantic (Greenland, Eastern United States, Eastern Canada) and Brazil.

The MS.221 and 222 had similar fixed landing gear to the MS.121, with its mainwheels on half-axles mounted centrally on a fixed transverse V-strut from the lower fuselage and their outer ends supported by dural-faired legs with multiple rubber ring shock absorbers from the lower longerons. The track was . Both variants had steerable tailskids to assist ground handling. In place of the cross-axle and its support, the MS.223 had simpler longitudinal V-struts, and each wheel had a vertical shock absorber leg to a reinforced forward wing strut.

It traveled the fastest and farthest (7.4 miles) during the race before high centering on an embankment. The sensors used by Sandstorm in 2004 included three fixed LIDAR laser-ranging units, one steerable LIDAR (in the globe on top), a radar unit (developed in collaboration with the Duke University Robotics Team), and a pair of cameras for stereo vision. Sandstorm also had an Applanix POS/LV system, providing a GPS and inertial navigation system for determining geographical position. Since the 2004 race Sandstorm has been continually tested and modified, logging hundreds of test miles.

On April 16, 2009 JSAT made its seventh order for an A2100-based satellite from Lockheed, the JCSAT-13 and Lippostar-1. It would feature 44 Ku band transponders with two steerable antennas for on-orbit reconfiguration. It was to be launched in 2013 for the 124°East slot where it would replace JCSAT-4A. The next day, April 17, Arianespace announced that they had secured the contract to launch JCSAT-13 on an Ariane 5 ECA. On March 23, 2012, JSAT announced that the expected launch date for JCSAT-13 was May 15.

The trench crossing capacity is 40 centimetres, a slope of 40% can be climbed. The P16 employs a Kégresse half-track drive developed by Citroën-Kégresse, without power transfer to the steerable front wheels. The track does not have real links, but consists of an internal steel band, embedded in rubber. The large sprocket is in front; behind it a central axle is located in the middle, on which rotates a section with two bogies, each holding two small road wheels, and a long double beam to the back, holding a large trailing wheel.

After their successful hydrogen balloon flights in 1783, professor Jacques Charles and the Robert brothers built an elongated, steerable craft that followed Jean Baptiste Meusnier's proposals. Their design incorporated Meusnier's internal ballonnet (air cell), a rudder, and a method of propulsion.Biographical dictionary of the history of technology, Volume 39 By Lance Day, Ian McNeil. Charles, Jacques Alexandre Cesar On 15 July 1784 the brothers flew for 45 minutes from Saint-Cloud to Meudon with M. Collin-Hullin and Louis Philippe II, the Duke of Chartres in their elongated balloon.

Article in Commercial Motor, 26 September 1922. pp. 168-169. The production model was a modified Yorkshire steam tractor, fitted with jacks at the front to allow a separate bogie to be manoeuvred into position underneath the front axle to guide it on the rails. Without the bogie, the vehicle could still be driven on ordinary roads and had the advantage of being able to be detached and run around the train, without requiring special loops for that purpose. For reversing on the track, as when shunting, the rear wheels were modified to be steerable.

The telescope was eventually completed in 1957, when it was the largest fully steerable radio telescope in the world. It remains in service as of 2016. According to Lovell, the project was completed using "a desk calculator and slide rule", which led to a "sturdy" construction with "quite a lot of redundancy in the steelwork" which Lovell later credited for the telescope's longevity. The structure is a rare example of a post-war grade-I-listed structure, denoting its "exceptional interest", and was voted Britain's top "unsung landmark" in a 2006 BBC poll.

Low-Gain Antennas are used for Launch and Early Orbit Phase (LEOP) and now function as a back-up during the mission phase when steerable Medium- and High-Gain Antennas are in use. The High-Temperature High-Gain Antenna needs to point to a wide range of positions to achieve a link with the ground station and to be able to downlink sufficient volumes of data. Its design was adapted from the BepiColombo mission. The antenna can be folded in to gain protection from Solar Orbiter's heat shield if necessary.

The STAR Tumor Ablation System is an FDA-cleared medical device that uses targeted radiofrequency ablation (also written t-RFA) to heat and destroy cancerous tumors caused by metastatic disease that has spread to the spine, causing severe pain and discomfort. STAR is not used as a treatment for cancer, but for pain relief. It is typically an outpatient procedure and can be performed using local anesthesia through a small incision. It works by placing a small steerable device into the vertebra which is guided by the physician to precisely target the tumor.

Juhani Heinonen, an aeronautical engineer who had previously worked for the Valmet aircraft factory at Tampere, and then for Finnair, designed a single-seat, single engined aerobatic sport aircraft, the Heinonen HK-1. It was a low winged monoplane of all-wooden construction, powered by a Walter Mikron air-cooled inline engine rated at driving a two-bladed propeller. Split flaps were fitted to the wings, while the aircraft had a fixed tailwheel undercarriage, with a steerable tailwheel but no brakes. The pilot sat under a sliding perspex canopy.

The Type 143 first flew on 11 June 1929, and successfully met all performance criteria.Mason 1992, p. 223. One of the six aircraft was evaluated by the Aeroplane and Armament Experimental Establishment (A & AEE) at Martlesham Heath before delivery to Bolivia. Vickers Type 177 A seventh aircraft, the Vickers Type 177 was built as a private venture to meet the requirements of Air Ministry Specification N.21/26 for a naval fighter, being fitted with a Jupiter XF engine and steerable wheel braking to aid on-deck manoeuvering.

Surveillance radar antenna More modern systems use a steerable parabolic "dish" to create a tight broadcast beam, typically using the same dish as the receiver. Such systems often combine two radar frequencies in the same antenna in order to allow automatic steering, or radar lock. Parabolic reflectors can be either symmetric parabolas or spoiled parabolas: Symmetric parabolic antennas produce a narrow "pencil" beam in both the X and Y dimensions and consequently have a higher gain. The NEXRAD Pulse-Doppler weather radar uses a symmetric antenna to perform detailed volumetric scans of the atmosphere.

Configured as a passenger aircraft, this space could seat twenty in five rows of four,Flight 18 September 1947 p.327 though there is no record that seats were installed. It had a tricycle undercarriage with stub axles mounted under the fuselage floor carrying short legs that bore a pair of small fixed main wheels, keeping the aircraft close to the ground for loading; the fuselage floor was only 2 ft (610 mm) above the ground. The nosewheel was steerable via the rudder bar as in the Aerovan.

The easy-to-fly design included unique design features, including a large glazed canopy - with almost as much visibility as a bubble canopy - for improved visibility. The prototype 310 featured an ERCO-made inverted four-cylinder engine, the ERCO I-L 116, which was quickly dropped due to its high manufacturing cost compared to the new Continental A-65 horizontal. Lacking rudder pedals, the Ercoupe was flown using only the control wheel. A two-control system linked the rudder and aileron systems, which controlled yaw and roll, with the steerable nosewheel.

The Bottom Hole Assembly (BHA) is made up of: a drill bit, which is used to break up the rock formations; drill collars, which are heavy, thick-walled tubes used to apply weight to the drill bit; and drilling stabilizers, which keep the assembly centered in the hole. The BHA may also contain other components such as a downhole motor and rotary steerable system(RSS), measurement while drilling (MWD), and logging while drilling (LWD) tools. The components are joined together using rugged threaded connections. Short "subs" are used to connect items with dissimilar threads.

Recreational activities include walking and picnicking as well as a playground for children. Visitors are allowed to explore both sides of the Canada–United States border inside the park, but are warned not to cross the boundary of the park to enter the adjacent country without being cleared to enter by the respective customs authority, as violators are subject to prosecution. Although no known cameras are in the park itself, United States Border Patrol agents in cars, on bikes, and on foot inside and steerable cameras on poles outside watch the park.

He said that he had done this with the help of a 50-foot tesla coil. Antonio Longoria in 1934 claimed to have a death ray that could kill pigeons from four miles away and could kill a mouse enclosed in a "thick walled metal chamber". During World War II, the Germans had at least two projects, and the Japanese one, to create so called death rays. One German project led by Ernst Schiebold concerned a particle accelerator with a steerable bundle of beryllium rods running through the vertical axis.

A tricycle undercarriage is standard, with (usually) spatted mainwheels on spring cantilever legs mounted on the fuselage at the base of the wing struts plus a spatted, steerable nosewheel. The mainwheels have brakes operated by a central hand control. A conventional undercarriage is an option, with the mainwheel legs fuselage-mounted further forward, below the cabin doors, plus a carbon-and-steel tailwheel. A variety of engines have been fitted. Early models used a 26 kW (35 hp) Rotax 447 or Jabiru, or a (37 kW) 50 hp Rotax 503.

A ballistic parachute is an option: either a Junkers or a BRS 5UL type may be fitted. A 74 kW (99 hp) Rotax 912 ULS is the standard powerplant but there are other options such as the 60 kW (80 hp) Rotax 912 UL or the Jabiru 2200 and Jabiru 3300 engines of similar power. One significant modification of the Breezer prototype after its first year of test flying was the incorporation of a steerable nosewheel in place of a castoring type. The Breezer obtained German certification in the Summer of 2001.

The tandem seat NV-4 with, enclosed cockpit, was a biplane with a central float integrated with the fuselage, in similar fashion to the Grumman J2F Duck. Constructed mainly of wood the wings were conventional in construction, with ribs built up over spars covered with plywood and fabric. The fuselage and integral tail unit were constructed from shpon (layers of birch ply glued over moulds and templates). A manually retractable undercarriage was housed either side of the central float, with the fixed steerable tailwheel doubling as a water-rudder.

Minitram was an automated guideway transit system studied by the Transport and Road Research Laboratory (TRRL), part of the UK Department of the Environment's Ministry of Transport. The system was based on small, completely automated tram-like vehicles of about 25 passengers that could be connected together into three-car trains to increase capacity. Proposed designs were submitted by Hawker Siddeley Dynamics (HSD) and EASAMS (part of GEC). HSD's system used rubber wheels and EASAMS' steerable steel ones, but the projects were otherwise similar and notably shared a linear motor for propulsion and most braking.

In June 2015, wreckage of an unidentified Falcon 9 launch vehicle was found off the coast of The Bahamas, which was confirmed by SpaceX CEO Elon Musk to be a component of the payload fairing that washed ashore. Musk noted the possibility of fairing reusability in a statement: "This is helpful for figuring out fairing reusability". In March 2017, SpaceX for the first time recovered a fairing from the SES-10 mission, aided by thrusters and a steerable parachute helping it glide towards a gentle touchdown on water. On 11 April 2019, SpaceX recovered both fairing halves during the Arabsat-6A mission.
|
|
On the SES-10 mission, one of the fairing halves performed a controlled atmospheric reentry and splashdown using thrusters and a steerable parachute; fairings are eventually slated to land on a floating "bouncy castle" structure. SpaceX began re-flight of previously launched booster stages in 2017. The first re-flight was accomplished in March 2017, nearly a year after the booster's maiden flight; the second was in June 2017, only five months after its maiden flight. Both were successful, and both insurers and launch service customers are readily supporting the newly emerging market in launch services provided by multiple-use boosters.

23 On entering service, two stern-mounted, short-length torpedo tubes for Mark 20 anti-submarine torpedoes. However, the development of steerable wire-guided torpedoes made the less-capable aft-firing torpedoes redundant; they were closed off, and later removed during a refit.Shaw, HMAS Onslow, p. 19 Otway was laid down by Scotts Shipbuilding and Engineering Company at Greenock, Scotland on 29 June 1965, The submarine was launched on 29 November 1966 by Princess Marina: the first RAN submarine and second RAN vessel after the cruiser to be launched by a member of the Royal Family.

The carriage was a large 4-wheeled box-trail design with two non-steerable wheels on the front and two castering wheels at the rear. The wheels were fitted with detachable grousers designed by Major Crispino Bonagente for traction on soft ground and was towed in one piece by a Pavesi-Tolotti artillery tractor. When not on the move the grousers were removed and the steel wheels rode on an inclined set of steel rails when in firing position. The steel rails were mounted on a firing platform made of wooden beams which allowed the gun 360° of traverse.

According to the Aetna Clinical Policy Bulletin on ENB, “In 2004, the FDA cleared for marketing through the 510(k) process the Medtronic superDimension/Bronchus system, also known as the inReach system (superDimension, Ltd, Israel), a minimally invasive image-guidance localization and navigation system that uses electromagnetic guidance for the management of peripheral lung lesions. The system consists of several components: a guide catheter, a steerable navigation catheter, and planning and navigation software and hardware (i.e., computer and monitor). Navigation is facilitated by an electromagnetic tracking system that detects a position sensor incorporated into a flexible catheter advanced through a bronchoscope.

In this landplane configuration a small steerable tailwheel was added. The split undercarriage allowed the 550 to launch torpedoes and bombs from a longitudinally divided bay beneath the fuselage, with a maximum weapons weight of 1,500 kg (3,100 lbs) and torpedoes carried on the port side. The first flight was made from Latécoère's marine base at Biscarosse on 29 April 1933 with the 550 in seaplane form. After some modifications to engine cowlings, wings and tail it went to CEPANA at Saint- Raphaël, Var for trials in October 1933 and in November was converted, in less than four hours, into a landplane.

At HF frequencies, however, refraction of the radar wavevector is greater, and this allows for the perpendicularity requirement to be met at high latitudes. Refraction of radio waves in the ionosphere is a complicated non-linear phenomenon governed by the Appleton–Hartree equation. In 1983, a steerable-beam HF radar with 16 log-periodic antennas began operations at Goose Bay, Labrador, Canada. Comparing measurements of F region ionopheric plasma velocity from the Goose Bay radar with the Sondestrom Incoherent Scatter Radar revealed that the Goose Bay radar was capable of measuring the F region plasma convection velocity.

The pilot's seat was positioned halfway between the wings and the tail surfaces: a passenger seat was fitted behind the engine. The main undercarriage employed oleo-pneumatic suspension, and there was a single steerable tailwheel. It was intended that lateral stability would be achieved by automatic differential movement of the two halves of the upper wing, this feature being the subject of a patent filed by Bréguet. In a turn, the greater speed of the outer wing would cause the angle of attack to be reduced, so eliminating the increase in lift that the greater speed would otherwise have produced.

Based upon the Avid Flyer, which it greatly resembles, the Mohawk features a strut-braced high wing, a two-seats-in-side-by-side configuration enclosed cockpit accessed via doors, fixed conventional landing gear and a single engine in tractor configuration. The aircraft is made from metal tubing, with its flying surfaces and fuselage covered doped aircraft fabric. Its span wing features Junkers flaperons, has a wing area of and is supported by "V" struts with jury struts. The plans specify standard hydraulic brakes, a steerable tailwheel and wings that fold for ground transport or storage.

ALLISS antenna as viewed underneath If there is an "S" in the antenna's designation, it is a steerable design. Following the ITU-recommendation, it might be called 'slewable design'. This might be achieved electronically by adjustment of the electrical wave phases of the signals fed to the columns of dipole antenna elements, or physically by mounting the antenna array on a large rotating mechanism. An example of this can be seen at NRK Kvitsøy, where a circular railway carries a pair of wheeled platforms, each of which supports a tower at opposite ends of a diameter-arm.

A Toro Z Master Commercial Zero-Turn mower A zero-turn riding lawn mower (colloquially, a z-turn) is a standard riding lawn mower with a turning radius that is effectively zero. Different brands and models achieve this in different ways, but hydraulic speed control of each drive wheel is the most common method. Both commercial duty and homeowner models exist, with varying engine power options, size of cutting decks, fuel type (gasoline or diesel), and prices. A z-turn mower typically drives faster and costs more than a similarly sized conventional riding mower that has steerable front wheels.

These are used to drive two steerable azimuth thrusters, with a bow thruster supplementing. Maximum speed is , and the Bay-class ships can achieve a range of at . Lyme Bay is armed with two 30 mm DS30B cannons, four Mk.44 miniguns, six 7.62mm L7 GPMGs, and two Phalanx CIWS. The standard ship's company consists of 60 officers and sailors. As a sealift ship, Lyme Bay is capable of carrying up to 24 Challenger 2 tanks or 150 light trucks in 1,150 linear metres of space. The cargo capacity is equivalent of 200 tons of ammunition, or 24 Twenty-foot equivalent unit containers.

They solved the control problem by inventing wing warping for roll control, combined with simultaneous yaw control with a steerable rear rudder. Almost as an afterthought, they designed and built a low-powered internal combustion engine. They also designed and carved wooden propellers that were more efficient than any before, enabling them to gain adequate performance from their low engine power. Although wing-warping as a means of lateral control was used only briefly during the early history of aviation, the principle of combining lateral control in combination with a rudder was a key advance in aircraft control.

Then, to manage the outliers, they augmented the small (i.e. low port density) network switches, commonly referred to as top-of-the-rack or ToR switches, which connect the server racks to the rest of the network, with extremely high frequency point-to-point radio frequency links. Notwithstanding concerns about link reliability due to interference, they used these short range, highly directional links advantageously, exploiting frequency_reuse to light-up many links concurrently and interference-free at multi-Gbps rates. The steerable radio beams provided additional inter-rack capacity on an as needed bases thus relieving congestion hot-spots.

Wooden draisine (around 1820), the earliest two-wheeler Drais's 1817 design made to measure The first verifiable claim for a practically used bicycle belongs to German Baron Karl von Drais, a civil servant to the Grand Duke of Baden in Germany. Drais invented his Laufmaschine (German for "running machine") in 1817, that was called Draisine (English) or draisienne (French) by the press. Karl von Drais patented this design in 1818, which was the first commercially successful two-wheeled, steerable, human-propelled machine, commonly called a velocipede, and nicknamed hobby-horse or dandy horse. It was initially manufactured in Germany and France.

The original single seat ES-1 Phoenix began as a rebuild by Edwin Sochen of a storm-destroyed Quicksilver MX but emerged a much refined aircraft, with two-surface wings, ailerons rather than spoilers and a fully steerable undercarriage. One of these was built and flown, then Sochen developed it into the CII two-seater. Seating apart, the two variants were generally similar. The two surface wing, tapered in plan with a straight leading edge and a forward swept trailing edge, was braced from below on each side by a single strut, assisted by jury struts.

The observatory's facilities include the Nanshan Radio Telescope (see List of radio telescopes#Asia), located in Gangou Township, Ürümqi County (). The 25 m, telescope site in Nanshan of XAO is one of the important stations of Very-long-baseline interferometry (VLBI). As a crucial research base for pulsar, centimeter wave molecular line and active galactic nuclei research, Nanshan station is also involved and plays an important role in China's Lunar Exploration Program. Plans also exist for the construction of a large, fully steerable single-dish radio telescope (diameter 110 m), which is called Qitai Radio Telescope, or QTT for short.

At the time of commissioning it was the second largest telescope operating in the world, after Lord Rosse's 6 foot reflector at Birr, Ireland, and it was the largest fully steerable telescope in the world. The telescope was designed to explore the nebulae visible from the southern hemisphere, and in particular to document whether any changes had occurred in the nebulae since they were charted by John Herschel in the 1830s at the Cape of Good Hope.Melbourne Observatory. (1885). Observations of the Southern Nebulae made with the Great Melbourne Telescope from 1869 to 1885, Part 1, Melbourne: Government Printer.

Working principle View to the East from the parabola center One of the 63 heliostats The principle used is the concentration of rays by reflecting mirrors (9,600 of them). The solar rays are picked up by a first set of steerable mirrors located on the slope, and then sent to a second series of mirrors (the concentrators), placed in a parabola and eventually converging on a circular target, 40 cm in diameter, on top of the central tower. Equivalent to concentrating the energy of "10,000 suns", the solar furnace produces a peak power of 3200 Kw.

More recent satellite phones are similar in size to a regular mobile phone while some prototype satellite phones have no distinguishable difference from an ordinary smartphone. Satphones are popular on expeditions into remote areas where terrestrial cellular service is unavailable. A fixed installation, such as one used aboard a ship, may include large, rugged, rack-mounted electronics, and a steerable microwave antenna on the mast that automatically tracks the overhead satellites. Smaller installations using VoIP over a two-way satellite broadband service such as BGAN or VSAT bring the costs within the reach of leisure vessel owners.

The world's first steerable radio telescope at Jodrell Bank was built at the University by Bernard Lovell. Since 1906, when former student Joseph Thompson won the Nobel Prize in Physics, the faculty and its antecedent institutions have produced more than 11 Nobel laureates in Physics out of the 25 awarded to staff or students of the University of Manchester as a whole. Most recently, Manchester physicists Andre Geim and Kostya Novoselov won the 2010 Nobel Prize in Physics for their pioneering work with graphene. The University's history is closely linked to Manchester's emergence as the world's first industrial city.

During the cruise stage, communications with the spacecraft were conducted over the X band using a medium-gain, horn-shaped antenna and redundant solid state power amplifiers. For contingency measures, a low-gain omni-directional antenna was also included. The lander was originally intended to communicate data through the failed Mars Climate Orbiter via the UHF antenna. With the orbiter lost on September 23, 1999, the lander would still be able to communicate directly to the Deep Space Network through the Direct-To-Earth (DTE) link, an X band, steerable, medium-gain, parabolic antenna located on the deck.

The fs26 Moseppl is a cantilever high-wing monoplane with a monocoque nacelle fuselage and a glassfibre/balsa sandwich wing structure, fitted with airbrakes but no flaps or ailerons. To make room for the engine the Moseppl has twin fins and rudders attached to the wing trailing edge with an all-moving tailplane between the tops of the vertically surfaces. The pilot sits in an enclosed cockpit with a transparent canopy and the landing gear is a retracting rear monowheel and non-steerable nosewheel. The rear-mounted engine is a Solo-Hirth engine with a variable pitch pusher propeller.

It was an outpost of the university's botany department and had been a searchlight station during the war. In the course of his experiments, he was able to show that radar echoes could be obtained from daytime meteor showers as they entered the Earth's atmosphere and ionised the surrounding air. He was later able to determine the orbits of meteors in annual meteor showers to show they were in solar orbit and not of interstellar origin. With university funding, he constructed the then-largest steerable radio telescope in the world, which now bears his name: the Lovell Telescope.

Gunston and Gilchrist 1993, pp. 83-84. A safety circuit prevented retraction of the landing gear until a sufficient air speed had been reached. The nose-wheel was steerable which was unusual for a British aircraft, the Sperrin being one of the first British aircraft to be fitted with one; the landing gear was operated by a Messier hydraulic system.Gunston and Gilchrist 1993, p. 84. A 24/28-volt DC electrical system was supplied by two generators; both generators and a compressor for cabin pressure were driven from two accessory gearboxes that were housed within the wings.

For the rest of the two crafts' passes over the near side of the Moon, Mattingly prepared to shift Casper to a circular orbit while Young and Duke prepared Orion for the descent to the lunar surface. At this point, during tests of the CSM's steerable rocket engine in preparation for the burn to modify the craft's orbit, a malfunction occurred in the engine's backup system. According to mission rules, Orion would have then re-docked with Casper, in case Mission Control decided to abort the landing and use the lunar module's engines for the return trip to Earth.

In 1924 he joined the Western Electric Company, and in 1925 became a research engineer at Bell Telephone Laboratories, where he helped develop short-wave radio receivers and field strength measuring equipment, and designed directional antennas for short-wave radio communication, including his celebrated rhombic antenna (1931). Karl Jansky used a steerable Bruce array in his earliest radio astronomy experiments, also in 1931. Bruce received the 1932 IEEE Morris N. Liebmann Memorial Award "for his theoretical investigations and field developments in the domain of directional antennas", and the Franklin Institute's 1935 Longstreth Award for inventing the rhombic antenna.

The next project of Jacques Charles and the Robert brothers was to build an elongated, steerable craft that followed Jean Baptiste Meusnier's proposals (1783–85) for a dirigible balloon. The design incorporated Meusnier's internal ballonnet (air cells), a rudder and a method of propulsion. Jacques Charles chose never to fly in this craft, but on July 15, 1784 the brothers flew for 45 minutes from Saint-Cloud to Meudon with M. Collin-Hullin and Louis Philippe II, the Duke of Chartres in La Caroline. It was fitted with oars for propulsion and direction, but they proved useless.

Brennan was born in Castlebar, Ireland, and moved to Melbourne, Australia in 1861 with his parents. He started his career as a watchmaker and a few years later was articled to Alexander Kennedy Smith, a renowned civil and mechanical engineer of the period. He served as a sergeant in the Victorian Engineers under the command of Captain J. J. Clark. Brennan invented the idea of a steerable torpedo in 1874, from observing that if a thread is pulled on a reel at an angle with suitable leverage, the reel will move away from the thread side.

The design of the new 1000 series trains is a modern rendition of the original 1000 series trains, which were originally used on the Ginza Line when the line opened in 1927. The new 1000 series uses newly developed bogies with steerable axles to reduce flange noise on sharp curves. Toshiba PMSM (permanent magnet synchronous motors) are used, offering 20% energy savings compared to the VVVF inverter controlled motors used in earlier 01 series trains. The trains are lit entirely with LED lights, including the headlights, offering energy savings of 40% when compared to fluorescent lighting.

NASA contacted the spacecraft using the X band communication link twice a week for command and status updates. Scientific data are downloaded once a month using the Ka band link at a maximum data transfer rate of approximately 550 kB/s. The high gain antenna is not steerable so data collection is interrupted for a day to reorient the whole spacecraft and the high gain antenna for communications to Earth.Kepler press kit The Kepler space telescope conducted its own partial analysis on board and only transmitted scientific data deemed necessary to the mission in order to conserve bandwidth.

The Apollo 16 Command and Service Module (CSM), as seen from the Lunar Module (LM, out of view) above terrain on the lunar farside. With the preparations finished, Young and Duke undocked Orion from Mattingly in the CSM Casper. Mattingly prepared to shift Casper to a circular orbit while Young and Duke prepared Orion for the descent to the lunar surface. At this point, during tests of the CSM's steerable rocket engine in preparation for the burn to modify the craft's orbit, a malfunction occurred in the engine's backup system, causing such severe oscillations that Casper seemed to be shaking itself to pieces.

Stainless steel wires forming the parabolic reflector The Ooty Radio Telescope has been designed and fabricated with domestic Indian technological resources. The ORT was completed in 1970 and continues to be one of the most sensitive radio telescopes in the world. Observations made using this telescope have led to important discoveries and to explain various phenomena occurring in the solar system and in other celestial bodies. The reflecting surface of the telescope is made of 1,100 thin stainless-steel wires running parallel to each other for the entire length of the cylinder and supported on 24 steerable parabolic frames.

The thermal noise of ionized gas plasma antennas is less than in the corresponding metal antennas at the higher frequencies. Solid state plasma antennas (also known as plasma silicon antennas) with steerable directional functionality that can be manufactured using standard silicon chip fabrication techniques are now also in development.Wireless at the speed of plasma New Scientist, published 2010-12-13, accessed 2010-12-14 Plasma silicon antennas are candidates for use in WiGig (the planned enhancement to Wi-Fi), and have other potential applications, for example in reducing the cost of vehicle-mounted radar collision avoidance systems.

The tops of the legs were further braced to the upper fuselage. Split axles were fixed at the bottoms of the forward lift struts; single wheels were fitted with balloon tyres and had differential brakes for ground steering. The first prototype had a steerable tailskid, replaced by a tailwheel in later aircraft. The first prototype, which first flew in 1930 and was designated E-30 H, was powered by an upright V-8 180 hp (134 kW) Hispano-Suiza 8Ab engine. It had a maximum speed of 180 km/h (112 mph) and a takeoff weight of 1,150 kg (522 lb).

A 'Birmingham Dribbler', Stevens's Model Dockyard, England, around 1890 Birmingham Dribbler or carpet railway describes a type of very early model railway. It is a bit of a misnomer, as the railway featured a model live steam railway locomotive, but no track – the locomotive was simply run across the floor. In some cases, the front wheels were even made steerable so that they could be run in a circle without track. Evidence is required of individual examples, but it is believed they first appeared in the 1850s and became generally popular in the latter part of the 19th through to the early 20th century.

Bednarik suggests that navigation had appeared by 1 Ma, possibly to exploit offshore fishing grounds. He has reproduced a primitive dirigible (steerable) raft to demonstrate the feasibility of faring across the Lombok Strait on such a device, which he believes to have been done before 850 ka. The strait has maintained a width of at least 20 km for the whole of the Pleistocene. Such an achievement by Homo erectus in the Early Pleistocene offers some strength to the suggested water routes out of Africa, as the Gibraltar, Sicilian, and Bab-el-Mandeb exit routes are harder to consider if watercraft are deemed beyond the capacities of Homo erectus.

As thermals can only be indirectly observed through the reaction of the aircraft to the invisible rising air currents, skill is required to find and stay in the thermals. Hang gliders are composed of rigid frame from which the fabric skin is attached, much like a triangular sailboat sail. The payload (and crew) are suspended or hung from the frame, and control is exercised through the movement of the harness in opposition to a control frame, Paragliders use a special type of steerable parachute for a wing. Control is exercised through lines that deform the trailing edge of the airfoil or the wing's end regions.

On February 9, 1999, the ABC show Nightline featured IDEO in a segment called The Deep Dive: One Company's Secret Weapon for Innovation. The segment featured Jack Smith of ABC touring the IDEO office and challenging the company to redesign the shopping cart in five days to demonstrate IDEO's process for innovation. The end result was a shopping cart with a nestable steel frame which holds removable plastic baskets to help deter theft and increase shopper flexibility. A dual child seat with a swing-up tray was also included in the design, as well as a cupholder, a scanner to skip the checkout line and steerable back wheels for maneuverability.

Both were driven by a 5 horse power electric motor, at up to 5 degrees per minute. The drive system was protected using over-pressure alarms, cut-outs and relief valves, as well as two alarms (one at the telescope, one at Jodrell). The main aim for the telescope when constructed was to use it in conjunction with the Lovell Telescope as a fully steerable interferometer to determine the sizes of radio sources. It was not known what size the radio sources would be, and so the optimal telescope separation was not known (the separation is inversely proportional to the resolution of the interferometer).

A beam waveguide antenna is a particular type of large steerable parabolic antenna in which the radio waves are transported in a beam between the movable dish and the stationary transmitter or receiver using multiple reflective surfaces. Beam waveguide antennas are used in large radio telescopes and satellite communication stations as an alternative to the most common parabolic antenna design, the conventional "front fed" parabolic antenna. In front feed, the antenna feed, the small antenna that transmits or receives the radio waves reflected by the dish, is suspended at the focus, in front of the dish. However, this location causes a number of practical difficulties.

The 328 is capable of operations from semiprepared airstrips and rough runways, incorporating features such as its retractable landing gear being equipped with high-floatation tyres and steerable nose gear and a gravel guard. It is equipped with a pair of Pratt and Whitney PW119C turboprop engines, which drive fully reversible Hartzell HD-E6C-3B propellers. The propeller blades generate notably less noise in comparison to their contemporary counterparts due to features such as their lower rotation speed, propeller synchrophasing, and the use of a six-blade configuration. The propeller system is dual-acting, being capable of adjusting pitch to maintain a constant engine speed.

The Pelican's conventional landing gear consists of a fibreglass rod for the main gear, with a tailskid, replaced on later models by a steerable tailwheel. The original Le Pelican was replaced in production by the single-seat Super Pelican which has taller landing gear and a Half VW engine of The single-seat Le Pelican production ran from 1983 to 1985, with about 100 kits delivered. Due to demand for two-seaters Lepage designed a new "clean-sheet" aircraft in 1984, which retained the same name as the earlier single-seater. The two-seat Pelican Club and its derivatives were built in large numbers, with more than 700 flying by 2003.

The Unimog was quite successful, except as originally intended as an agricultural platform. Daimler-Benz produced a new vehicle in 1972, the MB-trac, to be more oriented to larger scale mechanical farming. The new tractor crossed the Unimog technology of all-wheel drive and a power transmission to four large equal-sized wheels, with the appearance of a tractor: slim hood, behind it an angular, highly rising driver cab. In contrast to conventional tractors, the cab is situated between the axles, similar to large "four wheel drive" wheel loader - however, the steering is realized not by an articulated front and rear, but with a normal steerable front axle.

From 1914 to 1918 Anton Flettner worked at the German Ministry for War in the development of remote controls for air, water, and land vehicles. While employed under the aegis of Graf Zeppelin, Flettner also developed pilotless aircraft projects. At the age of 29, Flettner presented his first invention, a steerable torpedo, to the Kriegsmarine (German Imperial Navy) of World War I. This, and his next invention, a remote-controlled combat car, which was presented to the Heer (German Army), were rejected because they were not considered to be technically feasible. However, Flettner's efforts culminated in the prototype Siemens Schuckert Werke 1000 kg wire guided air to surface missile of 1918.

435th TFS F-4D in the Vietnam War, 1973. The Ford Aerospace AN/AVQ-10 Pave Knife was an early targeting pod developed by the USAF and US Navy to designate and guide laser-guided bombs. Pave Knife was developed in 1969 to replace the original, essentially improvised Airborne Laser Designator (ALD) and TRIM pod (see A-6 Intruder). ALD was not a pod but a hand-held laser operated by the weapon systems officer to mark targets for Paveway laser- guided bombs. Pave Knife was a roughly banana-shaped external pod, weighing about 550 kg (1,200 lb), containing a steerable laser and closed-circuit television camera.

The aircraft's distinctive shape features long, thin wings, in a flattened "W" shape, with a wingspan of , dual tailplanes, and four wheels (front and rear at each side). The rear wheels retract, but the front ones, which are steerable, are permanently deployed, with small fairings, referred to as "spats", in front. Another way to look at the overall shape is as two conventional planes, with very thin fuselages, side by side and joined together at their wingtips, with the cockpit and engines mounted at the point of joining. Although White Knight was developed for certain roles in the Tier One program, it is a very capable aircraft in its own right.

In England, starting in 1905, David Roberts of Richard Hornsby & Sons had attempted to interest British military officials in a tracked vehicle, but failed. Holt bought the patents related to the "chain track" track-type tractor from Richard Hornsby & Sons in 1914 for £4,000. Unlike the Holt tractor, which had a steerable tiller wheel in front of the tracks, the Hornsby crawler was steered by controlling power to each track. When World War I broke out, with the problem of trench warfare and the difficulty of transporting supplies to the front, the pulling power of crawling-type tractors drew the attention of the military.

The principle of the Ram-Air Multicell Airfoil was conceived in 1963 by Canadian Domina "Dom" C. Jalbert, but serious problems had to be solved before a ram-air canopy could be marketed to the sport parachuting community. Ram-air parafoils are steerable (as are most canopies used for sport parachuting), and have two layers of fabric—top and bottom—connected by airfoil-shaped fabric ribs to form "cells". The cells fill with higher- pressure air from vents that face forward on the leading edge of the airfoil. The fabric is shaped and the parachute lines trimmed under load such that the ballooning fabric inflates into an airfoil shape.

The tail wheel was both retractable and steerable. However, according to Cattaneo, the Re.2000 was afflicted by a major handicap in the form of the unavailability of reliable in-line engines of sufficient power; as such, the RE.2000 was able to represent only a limited advance over the Macchi C.200. The Re.2000 was powered by a single Piaggio P.XI RC 40 radial engine, which was capable of generating a maximum of of thrust; this drove a Piaggio-built three-blade constant speed variable-pitch propeller. This engine proved to be a major weak point of the aircraft in service as it proved to be not altogether reliable.

The two main wheels were attached, by two forked brackets, to the vertical members of a transverse rectangular chassis made of steel tubing, which transferred the weight of the engine at rest through the wheels to the ground. Each wheel was mounted behind its respective vertical member via two swivelling forked brackets, one horizontal and one sloping upwards at approximately 30 degrees, so that the two brackets and the vertical frame member formed a right-angled triangle. A helical compression spring on the vertical tube above the diagonal bracket provided a degree of sprung suspension while allowing the wheels, which were not steerable, to swivel independently.Macfie (Part 1), p.154.

The tank is also equipped with the NII Stali Upper Hemisphere Protection Complex, which consists of two steerable cartridges with 12 smaller charges each, and a turret-top VLS with two more similar cartridges, corresponding to the vehicle's soft kill APS. Additionally, using the AESA radar and anti-aircraft machine gun it is possible to destroy incoming missiles and slow-flying shells (except kinetic energy penetrators). In July 2015, the deputy director of the Uralvagonzavod tank manufacturing company claimed the T-14 would be invisible to radar and infrared detection due to radar-absorbing paint and the placement of components with heat signatures deep within the hull.

In 1993, Hughes Christensen introduced the AR-Series PDC bits, anti-whirl bits with increased penetration rates up to 100% in some applications and extended bit life as much as four- fold, compared to previous bit designs. By 1995, Hughes Christensen's Gold Series PDC line increased drilling efficiency by reducing the frictional forces that can accumulate in front of the cutting edge, reducing the energy required to remove the rock. In 1996, patented ChipMaster PDCs, known for their efficiency and durability, were built on the success of the Eggbeater product line. Hughes Christensen next introduced the Genesis HCM bits for steerable motors with patented EZSteer depth-of-cut control technology.

Eutelsat commissioned the launch of its Eutelsat 7C communications satellite, which provides 49 Ku band transponders for Sub-Saharan African digital television stations and capacity for several hundred channels in the region. The satellite also has optical communication capabilities for use by government services in Europe, the Middle East, and Central Asia, with a steerable beam capable of reaching areas visible to the satellite in its geostationary orbit above Africa. Eutelsat 7C was manufactured by Maxar Technologies and its design, intended for a lifespan of 15 years, is based on the SSL 1300 satellite bus. Weighing , the satellite uses electric propulsion for orbit maintenance, which reduces the satellite's launch mass.

The tricycle undercarriage consisted of a steerable, rearward- retracting nosewheel and long forward-retracting wing root-mounted main gear. The prototype was fitted with an apparently inoperable Heinkel He S 011 jet engine, but given the non-availability of this engine, a Jumo 004B was fitted for test flights. (Changing the type of engine was meant to be comparatively easy.) In addition, the production model was to be equipped with a pressurized cockpit and armored canopy,Me P.1101 - Luftarchiv and to be armed with two or four MK 108 cannons, Ruhrstahl X-4 air-to-air missiles, or both. USO personnel posing in front of the P.1101 V1 prototype.

This test was successfully completed in November 2016. In July 2017, Musk indicated that the architecture had "evolved quite a bit" since the 2016 articulation of the Mars architecture. A key driver of the updated architecture was to be making the system useful for substantial Earth-orbit and cislunar launches so that the system might pay for itself, in part, through economic spaceflight activities in the near-Earth space zone. In September 2018, a less drastic redesign was announced, stretching the second stage slightly and adding radially-steerable forward canards and aft fins, used for pitch control in a new reentry profile resembling a descending skydiver.

The key technology areas Escape Dynamics focused on were: i) externally powered aerospace vehicles; ii) efficient, reliable and safe wireless energy transfer; and iii) highly efficient high power microwave sources. Systems the company developed included high power microwave sources (gyrotrons) used to generate microwave energy required to power aerospace vehicles, high-speed steerable phased array antennas for millimeter-wave long distance wireless energy transfer, and electromagnetically powered propulsion systems. In the summer 2015, the company demonstrated operation of a prototype thruster with specific impulse above 500 seconds using helium as a propellant. The demonstration showed an end-to-end sequence of operation of an externally powered propulsion system.

Two more Progress D-18T turbofan engines were added to the new wing roots, bringing the total to six. An increased-capacity landing gear system with 32 wheels was designed, some of which are steerable, enabling the aircraft to turn within a runway. Like its An-124 predecessor, the An-225 has nose gear designed to "kneel" so cargo can be more easily loaded and unloaded. Unlike the An-124, which has a rear cargo door and ramp, the An-225 design left these off to save weight, and the empennage design was changed from a single vertical stabilizer to a twin tail with an oversized, swept-back horizontal stabilizer.

By 1941, the work on mounts was sufficiently well advanced to commence work on the armour plating of the guns, 150mm at the front, and 50mm on the sides, top and rear. New ammunition was also manufactured by Krupp. The barrels and their cradles were transported on trains to Saint Malo and one at a time put on a barge to Saint Peter Port Harbour Guernsey. A large 100 ton Dutch floating crane was towed from Le Havre, it was needed to lift each 51 ton barrel and breach and 38 ton mounting from the barge onto a trailer with 48 tyres on 12 steerable axles.

Alfa Romeo built the Mille in a rear-wheel drive 4x2 configuration. The Mille could carry eight metric tons of cargo in the bed and a tow up to 18 tons; a fifth wheel tractor unit version was also made, rated for a 26.2 ton towing capacity. Independent firms offered conversion to three or four axles by adding one or two dead axles, steerable or fixed; maximum bed payload went up respectively to over 10 or 13 tons. Italian Bartoletti made a car transporter version of the Mille in 1963, which could carry up to eight cars on two levels of the car and trailer.

The mainwheels have brakes and the nosewheel is steerable. The first M212 is powered by a 112 kW (150 hp) Lycoming O-320-ED flat-four engine driving a three-bladed propeller. Other engines have been considered, including the 134 kW (180 hp) Superior X-360, a flat-four related to the Lycoming O-360, and the 134-149 kW (180-200 hp) DeltaHawk DH180A4 liquid- cooled, four-cylinder, two-stroke Diesels. The M212 was initially intended to feature a Zoche aero-diesel ZO 01A, a radical single-row "cross-4" engine of 2,660 cc (162 cu in), producing up to 150 hp (112 kW) @ 2500 rpm.

At the rear of the Possum the fabric-covered wooden empennage was conventional. The fin had a straight and vertical leading edge but a curved top that blended into a rounded rudder which extended downwards between separate elevators; the tailplane was mounted just above the fuselage. Underneath, unusually for the time, there was a tailwheel rather than a skid, which was steerable and fitted with an automatic brake which provided increasing resistance with increasing load, unless the pilot overrode it. The main undercarriage was less innovative, with a pair of wheels single axle- mounted on short oleo legs to the wings with rear bracing.

The Skynet 5 satellite is based on the Eurostar E3000 bus design, weighs about , has two solar panels each about fifteen metres long, and has a power budget of five kilowatts. It has four steerable transmission dishes, and a phased-array receiver designed to allow jamming signals to be cancelled out. They will also resist attempts to disrupt them with high-powered lasers. Astrium described in 2010 the Skynet 5 system as: The first of the constellation of Skynet 5 vehicles (Skynet 5A) was launched by an Ariane 5 rocket at 22:03 GMT on 11 March 2007, in a launch shared with the Indian INSAT 4B civil communications satellite, and entered full service on 10 May 2007.

Since the rocket is not steerable, the photographer can not determine what the camera will photograph. Stock models of the Astrocam were intended to take their photographs after the rocket had begun to descend after reaching apogee. However, in the Winter 1993 issue of the Estes Educator News magazine, two sets of instructions (Lookdown Astrocam, and the Lookdown Astrocam MK11) were included describing how the camera could be converted to look back down the length of the rocket before reaching apogee, or upon a staging event. Estes catalogs showed some of the photographs from these modified rockets, but never produced a version designed to look down, or be capable of being switched at will.

MISA is a broad-based observatory capable of addressing a wide range of atmospheric science investigations. The incoherent scatter radar facility at Millstone Hill has been supported by the National Science Foundation since 1974 for studies of the Earth's upper atmosphere and ionosphere. During this time the facility has evolved from a part-time research operation sharing radar cooling and power supply elements with the M.I.T. Lincoln Laboratory Millstone satellite tracking radar, to a separately funded, operationally independent system dedicated to upper atmospheric research. The scientific capability of the Millstone Hill facility was greatly expanded in 1978 with the installation of a fully steerable 46 meter antenna to complement the 67 meter fixed zenith pointing dish.

Two MAN SE ballast tractors pulling and one Mercedes pushing a transformer on 10-axle lowboy trailer ALMA antenna in transit on a self-propelled modular transporter A heavy hauler is a very large transporter for moving oversize loads too large for road travel without an escort and special permit. A heavy hauler typically consists of a heavy tractor unit and multi-axled lowboy flatbed trailer. Some trailers may have independently steerable wheels, and several might be towed by one or more tractor units in a train. Self-propelled modular transporters, some featuring a dozen and more self-steering axles with scores of rubber tires to spread out a load, are increasingly being manufactured.

Vehicles were exported to Australia, New Zealand and Finland, generally as a kit of parts, with bodywork and batteries being sourced locally, and a left-hand drive option was also available. Production moved to a new factory on Brunswick Street, South Wigston in 1935 and this allowed them to build complete vehicles, whereas the manufacture of bodies had previously been outsourced to the Brush Electrical Engineering Company in Loughborough. They also bought in axles and braking systems, but the chassis, motor, and controller were made in-house. One early failure was the Trilec, a 3-wheeled vehicle with two steerable wheels at the front and a fixed motorised wheel at the back.

At the same time, the Mark 23 torpedoes were replaced by the United States Mark 48 wire-guided torpedo. As of 1996, the standard payload of Onslow was a mix of 20 Mark 48 Mod 4 torpedoes and Sub Harpoon missiles. Some or all of the torpedo payload could be replaced by Mark 5 Stonefish sea mines, which were deployed through the torpedo tubes. The submarine's secondary armament consisted of two stern- mounted, short-length torpedo tubes: these were intended for use against pursuing submarines, but the development of steerable wire-guided torpedoes shortly after the boat entered service made these redundant, and they were closed off during the 1982-84 refit.

The tail surfaces were again Dacron covered steel, wire braced with the tailplane placed at the bottom of the boom and with the lower rudder and a small ventral fin projecting below it. The Draggin' Fly had a fixed tricycle undercarriage, the mainwheels mounted on two V-form struts and half- axles hinged to the fuselage underside. All undercarriage legs used spring and rubber in compression type shock absorbers; the nose wheel was steerable. For its first flight and first eight hours of flight testing the Draggin' Fly was powered by a 36 hp (29 kW), 1.2 L Volkswagen engine but this was then replaced by a more powerful Volkswagen variant producing 50 hp (37 kW).

Directing a pen through a maze printed on paper—or guiding a steerable object - through a maze - requires the ability to project onto the steered object. In evaluating OZNAKI, an Australian educational robotics project inspired by Seymour Papert's Logo programming language, students were tested on Porteus-inspired tests, and on Piaget's Mountains Puzzle. Statistically significant enhancement was measured with senior primary and junior secondary students over just eight sessions with OZNAKI in lieu of other math lessons. Compared to control groups (who had "normal" math lessons) Cohen and Green's findings indicate that the capability measured by the tests is not intrinsic and should not be seen as a measure of intrinsic intelligence.

In December 1965 a Volkswagen 1200 Beetle was issued in East African Safari finish (256). This model featured an opening boot and engine cover and steerable front wheels operated by a spare tyre on the roof of the car. Three years later, in July 1969, Corgi issued the winning Hillman Hunter from the 1968 London to Sydney Marathon (302), complete with Take-Off Wheels, roof mounted tool box and a plastic kangaroo guard across the front of the car. This time the packaging included a model kangaroo and details of the event, and in February 1970 a model of the unique 4wd Ford Capri 3-Litre rally car (303) driven by Roger Clark was released.

In October 1964 a Police Dog Handler Mini van (450) was introduced painted dark blue with 'Police' in white letters on the sides, a nylon aerial fitted to the front wing and came with models of the police dog handler and police Alsatian dog. The Volkswagen European Police Car (492) issued in May 1966 was finished in the green and white of the German police force, and carried 'Polizei' transfers on the doors. It featured steerable front wheels operated by the blue metal 'light' on the roof and two policemen sitting inside the vehicle, not to mention opening boot and rear engine cover. Another rear engined police car was introduced in May 1968, the Sunbeam Imp 'Panda' car (506).

The Corgi design team came up with the first model with an opening feature in February 1960, the Aston Martin DB4 (218) which had an opening bonnet. Steerable front wheels, jewelled headlights and rear lights and an opening boot complete with spare wheel were added on the Bentley Continental Sports Saloon (224) in April 1961, and by October 1963 with the release of the Ghia L6.4 (241) new levels of authenticity were reached. This model featured a number of 'firsts' with not only an opening bonnet, but also opening doors and boot, and a detailed interior with a rear view mirror, folding front seats, and even a model corgi dog sitting on the rear parcel shelf.

Bernard Lovell built the Transit Telescope at Jodrell Bank in the late 1940s. This was a -diameter radio telescope that could only point directly upwards; the next logical step was to build a telescope that could look at all parts of the sky so that more sources could be observed, as well as for longer integration times. Although the Transit Telescope had been designed and constructed by the astronomers that used it, a fully steerable telescope would need to be professionally designed and constructed; the first challenge was to find an engineer willing to do the job. This turned out to be Charles Husband, whom Lovell first met on 8 September 1949.

There is a monument in Wentworth at the junction of the Darling and Murray Rivers in Australia commemorating the time in 1956 when both rivers flooded and a fleet of little grey Fergies was used to build levee banks to save the town. Commonwealth Trans-Antarctic Expedition A fleet of seven Ferguson TE-20s was used on the 1955–58 Commonwealth Trans-Antarctic Expedition which was led by Edmund Hillary. Four petrol-engined and three diesel models were used. Some were supplied as half-tracks, with steerable front skis, whilst others of the New Zealand team were fitted with an extra wheel on each side and full caterpillar tracks, developed by the expedition in the Antarctic.

The tripod-mounted optical tracking unit The Tan-SAM 1 missile is cruciform in cross section with four clipped delta wings attached to the mid body, and four small steerable clipped delta fins at the rear of the missile. The missile is propelled by a solid rocket motor, with giving it a burn-out velocity of about Mach 2.4. It is initially inertially guided to a likely intercept point, with an all-aspect infra-red seeker taking over to handle terminal guidance. The missile has a 9.2-kilogram fragmentation warhead triggered either by contact or a radar proximity fuze with a lethal radius of between 5 and 15 meters depending on the target type.

An M-series car was sent to the Motor Industry Research Association in 1971 for crash testing, and it was the only vehicle that remained steerable after a front-end collision with a concrete wall. Indeed, the engine remained in position through the impact, the doors were still openable, and the steering column had actually moved forward (away from the driver.) This last fact almost caused the MIRA officials to require that the car be re-tested, as they presumed that such as result was not possible and was a result of a fault with their measurement instruments. Mike Bigland was able to demonstrate to the officials that the result was legitimate, and approval was granted.

The dirigible balloon created by Giffard in 1852 Work on developing a dirigible (steerable) balloon, nowadays called an airship, continued sporadically throughout the 19th century. The first sustained powered, controlled flight in history is believed to have taken place on 24 September 1852 when Henri Giffard flew about in France from Paris to Trappes with the Giffard dirigible, a non-rigid airship filled with hydrogen and powered by a steam engine driving a 3-bladed propeller. In 1863, Solomon Andrews flew his aereon design, an unpowered, controllable dirigible in Perth Amboy, New Jersey. He flew a later design in 1866 around New York City and as far as Oyster Bay, New York.

The Green Bank Observatory (previously National Radio Astronomy Observatory, Green Bank) is an astronomical observatory located in the National Radio Quiet Zone in Green Bank, West Virginia, U.S. It is the operator of the Robert C. Byrd Green Bank Telescope, the world's largest fully steerable radio telescope. The observatory was established as the National Science Foundation's (NSF) National Radio Astronomy Observatory (NRAO) in 1956, and made its first observations in 1958. It served as the NRAO's headquarters until 1966, after which the facility was known as the National Radio Astronomy Observatory, Green Bank. In October 2016, the observatory became an independent institution, following a 2012 recommendation that the NSF fully divest itself from the facility by October 1, 2016.

The car contained novel ideas that have since become reality: interchangeable fuel cell power units; interchangeable bodies; interactive computer navigation, mapping, and auto information systems; and four driving and steering wheels. The concept of some form of compact nuclear propulsion device was included as a possible power source on the assumption that radiation issues could be overcome without the need for prohibitively bulky shielding. The car had six wheels, with four steerable ones at the front and two fixed ones at the rear – similar to the fictional six-wheel 1965 FAB1 and the real Tyrrell P34 racing car of the mid-1970s. The designers determined the six-wheel concept would enhance tracking, traction, and braking.

With basically no equipment, the instruction consisted of "jump and pull" and windage was calculated by throwing an Eaton's catalogue out the door. Early operations were comical, but in early 1943 May sent two volunteers, Owen Hargreaves and Scotty Thompson to the smoke jumpers school in Missoula, Montana to be trained by the U.S. Forest Service. After six weeks they returned home with borrowed steerable equipment to train two other volunteers, Wilfred Rivet and Laurie Poulsom. Soon the unit was conducting operational jumps, and by 1944 May's persistence had paid off and an official para-rescue training program started. For his work, May was awarded a Medal of Freedom with Bronze Palm in 1947 by the USAAF.

NCRA has set up a unique facility for radio astronomical research using the metrewavelengths range of the radio spectrum, known as the Giant Metrewave Radio Telescope (GMRT), it is located at a site about 80 km north of Pune. GMRT consists of 30 fully steerable gigantic parabolic dishes of 45m diameter each spread over distances of up to 25 km. GMRT is one of the most challenging experimental programmes in basic sciences undertaken by Indian scientists and engineers. GMRT is a unique instrument which opens up the sky at the Metrewave range of the Electromagnetic spectrum and using the technique of Aperture synthesis allows to make high sensitive maps of the sky.

Sir Henry Charles Husband (30 October 1908 – 7 October 1983), often known as H. C. Husband, was a leading British civil and consulting engineer from Sheffield, England, who designed bridges and other major civil engineering works. He is particularly known for his work on the Jodrell Bank radio telescopes; the first of these was the largest fully steerable radio telescope in the world on its completion in 1957. Other projects he was involved in designing include the Goonhilly Satellite Earth Station's aerials, one of the earliest telecobalt radiotherapy units, Sri Lanka's tallest building, and the rebuilding of Robert Stephenson's Britannia Bridge after a fire. He won the Royal Society's Royal Medal and the Wilhelm Exner Medal.

The Cartosat-1 satellite has two panchromatic cameras with 2.5 m spatial resolution, to acquire two images simultaneously, one forward (PAN FORE) looking at +26° and one aft (PAN AFT) of the satellite at -5° for near instantaneous stereo data. The time difference between the acquisitions of the same scene by the two cameras is about 52 seconds. The spacecraft body is steerable to compensate the Earth rotation effect and to force both fore and aft cameras to look at the same ground strip when operated in stereo mode. The cameras are mounted on the satellite in such a way that near simultaneous imaging of the same area from two different angles is possible.

The tailplane is attached to the top of the fuselage, with a trim tab on the elevator; the fin and rudder are curved, the fin extended forward by a lengthy fillet. The R-53 is powered by a 155 hp (116 kW) Blackburn Cirrus Major four-cylinder inverted inline engine, distinguishing it from the short-nosed radial engine installation on the R-52. It has a fixed conventional undercarriage with mainwheels fitted with brakes on independent hinged V-form legs with oil spring shock absorbers in separate, more upright, struts from the X-intersection of the wing struts, made more rigid by a secondary strut to mid-fuselage. The tail wheel is steel sprung and steerable.

For research into Tricycle undercarriages D.W.L. converted the prototype RWD 9 to the RWD 20 fitting a 130 hp Walter Major engine, steerable noseleg, moving the main undercarriage legs rearwards, and removing the rear seats door and windows which were faired over with plywood. Extensive testing was carried out with take-offs, landings and taxiing on different surfaces including unprepared fields as well as ploughed land. Conversion was completed in 1938 and the flight trials proved the stability and manoeuvrability of the tri- cycle undercarriage during extensive taxiing trials, (landings and take-offs were carried out with the nosewheel steering locked). The fate of the RWD 20 is unknown but it did not survive WWII.

The Jodrell Bank Observatory, located near Goostrey and Holmes Chapel in Cheshire, has played an important role in the research of meteors, quasars, pulsars, masers and gravitational lenses, and was heavily involved with the tracking of space probes at the start of the Space Age. The main telescope at the observatory is the Lovell Telescope, which is the third largest steerable radio telescope in the world. There are three other active telescopes located at the observatory; the Mark II, as well as 42 ft and 7m-diameter radio telescopes. Jodrell Bank Observatory is also the base of the Multi-Element Radio Linked Interferometer Network (MERLIN), a National Facility run by the University of Manchester on behalf of the Science and Technology Facilities Council.

The Vanwall, however, had been re-coloured red. It was followed in December 1964 by the Lotus-Climax F1 car (155). Finished in an authentic British Racing Green and carrying racing number 1, it represented Jim Clark's 1963 world championship winning Lotus 25, and in 1967 it was joined by the Cooper- Maserati F1 car (156) painted blue. The Lotus-Climax and the Cooper-Maserati were re-engineered in 1969 to include steerable front wheels operated by moving the driver from side to side, and a high level rear wing in the style of real Formula 1 cars of the time. They were re-coloured orange in the case of the Lotus-Climax (158) and yellow in the case of the Cooper-Maserati (159).

Cugnot's "Fardier à vapeur" ("Steam wagon") of 1769 Nicolas-Joseph Cugnot's "machine à feu pour le transport de wagons et surtout de l'artillerie" ("fire engine for transporting wagons and especially artillery") was built in two versions, one in 1769 and one in 1771 for use by the French Army. This was the first steam wagon that was not a toy, and that was known to exist. Cugnot's fardier a term usually applied to a massive two wheeled cart for exceptionally heavy loads, was intended to be capable of transporting 4 tonnes (3.9 tons), and of travelling at up to 4 km/h (2.5 mph). The vehicle was of tricycle layout, with two rear wheels and a steerable front wheel controlled by a tiller.

Illustration of how multiple airdrops with multiple drop zones, given they are within 25 miles of each other, can be accomplished at once using JPADS The Joint Precision Airdrop System (JPADS) is an American military airdrop system which uses the Global Positioning System (GPS), steerable parachutes, and an onboard computer to steer loads to a designated point of impact (PI) on a drop zone (DZ). The JPADS family of systems consists of several precision airdrop systems, ranging from extra light to heavy payloads. JPADS is used in conjunction with mission planning software that resides on a laptop. The function of this mission planning software includes computing release points, weather forecasting, acquiring measurements of wind velocity, altitude, air pressure, and temperature.

As the landing gear rows are spaced about apart from each other, the Pelican's wheel span may meet the code letter F standard of the International Civil Aviation Organization (ICAO) Aerodrome Reference Code, which is used for airport planning purposes. While only the nose landing gear can be steered on most airliners, each landing gear on the Pelican is steerable, so the aircraft can more easily perform crosswind landings and complete turns at a smaller radius when it is on the ground. The combined 76 aircraft tires on the Pelican far exceeds the 32 wheels of the current largest cargo aircraft, the Antonov An-225. The average load per wheel is , or meaningfully larger than the typical maximum design load of for large, long-range aircraft.

The rudder pedals also control a steerable nosewheel, but the hand-operated disc brakes are not differential and do not contribute to steering. The AE75 engine, a inverted three-cylinder water-cooled two-stroke unit with dual ignition and a 2.7:1 reduction gearbox,"Air Pictorial" magazine April 1986 was specially developed for the ARV by Hewland from their existing two-cylinder microlight engine. The AE75 engine has a TBO of only 800 hours, and, in the absence of continuing factory support, many ARVs have had their AE75s replaced with engines such as the Rotax 912, the Rotax 914, or the Jabiru 2200.Civil Aviation Authority (United Kingdom), GINFO Search Results, retrieved 15 December 14 Three ARVs were originally manufactured with the MidWest twin- rotor wankel engine.

A process called "stacking" thus allows the telescope operator to optimize the adjustments of the mirrors. The telescope is also unusual in that during an observation, the mirror remains at a fixed altitude and azimuth, and the image of an astronomical target produced by the telescope is tracked by the "payload", which resides at the position of prime focus and includes the SAC and prime focus instrumentation. This is similar in operation to the Arecibo Radio Telescope. Although this results in only a limited observing window per target, it greatly simplifies the primary mirror mount, when compared to a fully steerable telescope, transferring the complexity to the smaller and lighter payload tracking system, providing for an overall reduction in total telescope construction cost.

In the late 1970s it became clear that the satellites were not as universally useful as originally thought, notably at high latitudes or where signal security was an issue. For these reasons, the U.S. Air Force installed the Alaska Air Command MBC system in the 1970s, although it is not publicly known whether this system is still operational. A more recent study is the Advanced Meteor Burst Communications System (AMBCS), a testbed set up by SAIC under DARPA funding. Using phase- steerable antennas directed at the proper area of the sky for any given time of day, the direction where the Earth is moving "forward", AMBCS was able to greatly improve the data rates, averaging 4 kilobits per second (kbit/s).

Picture taken at high altitude during the microbloon 2.0 flight from November 2012Bloon is a zero emission craft in development, which consists of a high-altitude balloon-borne capsule to perform manned flights to near space and a steerable parachute system for returning autonomously to Earth. It also refers to the balloon-borne craft prototype range of the same company: Bloon, minibloon, microbloon and nanobloon which are differentiated among them by their size. Considering that only a helium balloon is responsible for lifting the load above most of the atmosphere, it is considered a zero emission craft. With this technology, Bloon would carry up to 4 passengers and 2 pilots (6 total crew) to an altitude as high as 36 km (22 mi, 118,110 feet).

This approach can reveal deformations of the brain parenchyma and displacements of arteries due to cardiac pulsatility and CSF flow. aMRI has thus far been demonstrated to amplify motion in brain tissue to a more visible scale, however, can in theory be applied to visualize motion induced by other endogenous or exogenous sources in other tissues. aMRI uses video magnificent processing methods such which uses Eulerian Video Magnification and phase- based motion processing, with the latter thought to be less prone to noise and less sensitive to non-motion induced voxel intensity changes. Both video- processing methods use a series of mathematical operations used in image processing known as steerable-pyramid wavelet transformation to amplify motion without the accompanying noise.

A drawbar is mounted or located on the tractive vehicle and is used to accept the coupling of the load. The direction of haulage may be push or pull, though pushing tends to be for a pair of ballast tractors working one pulling and the other pushing an exceptional load on a specialist trailer. The drawbar should not be confused with the fifth wheel coupling. The drawbar requires a trailer which either loads the drawbar lightly (for example a small boat trailer, or caravan, where a load of up to ~ is part of correct trailer loading practice), or the load is the weight of the coupling components only (larger trailers, usually but not always with a steerable hauled axle, front or rear).

The Counter-electronics High Power Microwave Advanced Missile Project (CHAMP) is a joint concept technology demonstration led by the Air Force Research Laboratory, Directed Energy Directorate at Kirtland Air Force Base to develop an air-launched directed-energy weapon capable of incapacitating or damaging electronic systems by means of an EMP (electromagnetic pulse). On October 22, 2012, Boeing announced a successful test of the missile. CHAMP disabled seven different targets before self-destructing over empty desert.Boeing's Counter- Electronics High Power Microwave Advanced Missile Project - Business Insider The U.S. Air Force expects to have technology for a steerable counter- electronics weapon “available” in 2016, when a multi-shot, multi-target, high- power microwave (HPM) package will be tested aboard an AGM-86 ALCM.

The technique of wing-warping is described, but the patent explicitly states that other methods instead of wing-warping could be used for adjusting the outer portions of a machine's wings to different angles on the right and left sides to achieve lateral (roll) control. The concept of varying the angle presented to the air near the wingtips, by any suitable method, is central to the patent. The patent also describes the steerable rear vertical rudder and its innovative use in combination with wing-warping, enabling the airplane to make a coordinated turn, a technique that prevents hazardous adverse yaw, the problem Wilbur had when trying to turn the 1901 glider. Finally, the patent describes the forward elevator, used for ascending and descending.

A beam waveguide antenna is a type of complicated Cassegrain antenna with a long radio wave path to allow the feed electronics to be located at ground level. It is used in very large steerable radio telescopes and satellite ground antennas, where the feed electronics are too complicated and bulky, or requires too much maintenance and alterations, to locate on the dish; for example those using cryogenically-cooled amplifiers. The beam of incoming radio waves from the secondary reflector is reflected by additional mirrors in a long twisting path through the axes of the altazimuth mount, so the antenna can be steered without interrupting the beam, and then down through the antenna tower to a feed building at ground level.

Just to the northeast of the village is the hill called Pen y Foel which is 123m above sea level; between 1951 and 1956 this was the site of a VHF Fixer station, part of the RAF Western Sector, and was one of a number similar fixed sites managed by RAF Longley Lane near Preston in Lancashire. The site contained an octagonal wooden hut with a hand- steerable radio mast with two radio receivers of type R1392D, transmitter and telephone line. This hut was protected by a close surrounding octagonal brick wall to provide some bomb blast protection which still exists. The station was used to allow each sector to locate RAF or allied aircraft and to help pilots find airfields in low cloud weather conditions.

F-16CJ of the alt=Jet heavily armed with weapons under wings taking off. The F-16 has a cropped-delta wing incorporating wing-fuselage blending and forebody vortex-control strakes; a fixed-geometry, underslung air intake (with splitter plate) to the single turbofan jet engine; a conventional tri-plane empennage arrangement with all- moving horizontal "stabilator" tailplanes; a pair of ventral fins beneath the fuselage aft of the wing's trailing edge; and a tricycle landing gear configuration with the aft-retracting, steerable nose gear deploying a short distance behind the inlet lip. There is a boom-style aerial refueling receptacle located behind the single-piece "bubble" canopy of the cockpit. Split-flap speedbrakes are located at the aft end of the wing-body fairing, and a tailhook is mounted underneath the fuselage.

The Arma 6x6 is motorised with a 450 hp water-cooled turbo diesel capable of running on F-34 or F-54 fuel drives the wheels through an automatic gearbox and single-speed transfer box, giving it a top speed of 105 km/h and a power/weight ratio of 24.3 hp/tonne. This also powers the onboard 24 V direct currentDC electrical system, which incorporates two maintenance- free 125 Ah batteries and a 3.3 kW converter. Arma's front two axles are steerable enabling it to make a turning radius of 7.85 m and the vehicle rides on independent hydropneumatic suspension, offering respectable off-road mobility and comfort. It can negotiate 45-degree approach and departure angles leading onto 60 per cent inclines and 30 per cent side-slopes.

The company developed two designs of steerable torpedo, the first to the design of Colonel Lay which were demonstrated to both the Admiralty, and the second to an Australian design. In 1882 Heenan & Froude were appointed structural engineers to the Blackpool Tower, supplying and constructing both the main tower, the electric lighting and the steel front pieces for the aquariums. After purchasing a factory in Birmingham, West Midlands in 1902, the company greatly expanded after incorporating and moving its headquarters to Worcester in 1903. By then a general purpose engineering company, they made: exhaust and mine ventilating fans; colliery and mining plant; belts, conveyors and elevators; sawing machines; bench chains; water dynamometers; spherical, horizontal and vertical engines; patent water boilers; bridge and roof iron work; and refuse destructors.

Some argued that the airship reports were genuine accounts. Steerable airships had been publicly flown in the U.S. since the Aereon in 1863, and numerous inventors were working on airship and aircraft designs (the idea that a secretive inventor might have developed a viable craft with advanced capabilities was the focus of Jules Verne's 1886 novel Robur the Conqueror). In fact, two French Army officers and engineers, Arthur Krebs and Charles Renard, had successfully flown in an electric-powered airship called La France as early as 1885, making no fewer than seven successful flights in the craft over an eleven-month period. Also during the 1896–97 period, David Schwarz built an aluminum-skinned airship in Germany that successfully flew over Tempelhof Field before being irreparably damaged during a hard landing.

These holds were a new safety feature that Andrée had reluctantly been persuaded to add, whereby ropes that got caught on the ground could be more easily dropped. Most of the ropes unscrewed at once and of rope were lost, while the three explorers could simultaneously be seen to dump of sand overboard to get the basket clear of the water. of essential weight was thus lost in the first few minutes. Before it was well clear of the launch site, Eagle had turned from a supposedly steerable craft into an ordinary hydrogen balloon with a few ropes hanging from it, at the mercy of the wind; its crew had no means to direct it to any particular goal and had too little ballast for stability.Med Örnen mot polen, p. 84.Lundström, pp. 75–76.

The Lovell Telescope is a radio telescope at Jodrell Bank Observatory, near Goostrey, Cheshire in the north-west of England. When construction was finished in 1957, the telescope was the largest steerable dish radio telescope in the world at 76.2 m (250 ft) in diameter; it is now the third-largest, after the Green Bank telescope in West Virginia, United States, and the Effelsberg telescope in Germany. It was originally known as the "250 ft telescope" or the Radio Telescope at Jodrell Bank, before becoming the Mark I telescope around 1961 when future telescopes (the Mark II, III, and IV) were being discussed.Lovell, The Jodrell Bank Telescopes It was renamed to the Lovell Telescope in 1987 after Sir Bernard Lovell, and became a Grade I listed building in 1988.

At the rear of the fuselage a cantilever twin finned wooden tail unit was fitted to improve low-speed yaw control and stability. The spatted undercarriage legs were cantilevered from the engine nacelles and the fuselage under the nose with the main wheels fitted with 'Bendix' pneumatic brake units and the nosewheel steerable from the rudder bar. Any engine of around 150 hp could be fitted, but the prototype was fitted with 150 hp Cirrus Major four-cylinder inverted in-line engines fitted in nacelles at the junctions of the inner and outer wings. An RWD 9 was converted to the RWD 20, by fitting a tri-cycle undercarriage, to speed the development of the RWD 18s, with extensive trials carried out including rough and ploughed field landings, take-offs and taxiing.

KH-8 GAMBIT-3 Photographic Payload Section KH-8 Photographic Payload Section The Camera Optics Module of KH-8 consists of four cameras. The main camera of KH-8B (introduced in 1971) with a focal length of is a single strip camera, designed to gather high-resolution images of ground targets. In the strip camera the ground image is reflected by a steerable flat mirror to a diameter stationary concave primary mirror. The primary mirror reflects the light through an opening in the flat mirror and through a Ross corrector. At periapsis altitude of 75 nautical miles, the main camera imaged a 6.3 km wide ground swath on a wide moving portion of film through a small slit aperture, resulting in an image scale of 28 meter / millimeter.

Pavement loading from the Pelican may be comparatively low, though. Boeing claims that the aircraft's ground flotation characteristic, a measure tied to the ground's ability to keep a vehicle from sinking, at maximum takeoff weight is superior to that of the much-smaller McDonnell-Douglas DC-10, which imposes the most demanding flotation requirements among aircraft of its era. However, according to the designer of the Aerocon Dash 1.6 wingship (a larger, sea-based ground effect vehicle that was investigated by DARPA a few years before the Pelican was proposed), regular Pelican operation at airports with high water tables underground may result in a type of seismic wave that leads to cracks in airport terminal buildings and eventually causes greater damage within months.

Smith, John Q., and David A. Byrd; "Forty Years of Research and Development at Griffiss Air Force Base, June 1951-June 1991," RL-TR-92-45 Based on his early relationships with Watson Laboratories and experience on SAGE, Marchetti was able to obtain a contract from RADC for Avco RAD to design and build an experimental phased-array antenna system for allowing wide scanning on Pinetree and other future radars. Several AFCRC engineers were hired for this effort. Called the Steerable Array Radar and Communications (SARAC), the project was successfully completed, with a 15-by 15-foot prototype antenna having hundreds of transmitter and receiver elements that allowed multiple beams to be electronically scanned. Avco RAD was not successful in obtaining a production contract for the improved radars.

The Cresta Run and the SMTC were founded by devotees of sledding (tobogganing in English) who adopted a head-first (prone) technique of racing down an icy run, as opposed to the feet-first (supine) and somewhat faster luge race. Both evolving sports were natural extensions of the invention of steerable sleds during the early 1870s by British guests of the Kulm hotel in St. Moritz. The initial crude sleds were developed almost accidentally--as bored well-to-do gentlemen naturally took to intramural competition in the streets and byways of mountainous downtown St. Moritz posing a risk to each other and pedestrians alike. This gave impetus to steering the sleds, and soon runners and a primitive mechanism evolved to allow some steerage along the longer curving streets of the 1870s.

In 1973 the station had a selection of high frequency (HF) radio transmitters, including the Marconi HS31 (6 kW), HS51 (30 kW), HS71 (12 kW) and the Marconi MST (Marconi Self Tuner) 1200 (30 kW). There was also a selection of Racal Speedrace transmitters, one of which offered remote control of frequency and aerial parameters from Systems Control. The aerial farm had steerable log periodic antennae, dipoles, rhombics and bicones – all types of HF antenna. A 24-hour watch system, each consisting of an RAF sergeant, a junior technician (JT), a senior aircraftman (SAC) and a civilian radio technician was maintained which carried out preventive and corrective maintenance and also re-tuned the transmitters and their drive units as directed by Systems Control at RAF Stanbridge in Bedfordshire.

Helias Doundoulakis designed the cable suspension system which was finally adopted. Although the present configuration is substantially the same as the original drawings by George and Helias Doundoulakis, (although with three towers, instead of the original four as drawn in the original patent), the U.S. Patent office granted Helias Doundoulakis a patent, for the brothers' innovative idea. Two other assignees on the patent were friends William J. Casey, who later became director of the Central Intelligence Agency under President Ronald Reagan, and Constantine Michalos, an attorney. The idea of a spherical reflecting mirror with a steerable secondary has since been used in optical telescopes, in particular, the Hobby–Eberly Telescope and the Southern African Large Telescope. Construction began in mid-1960, with the official opening on November 1, 1963.

Calais The SR.N4 was the biggest hovercraft to have been completed upon its introduction. Its primary structure comprised a large modular buoyancy tank, the internal structure of which being divided into 24 watertight compartments.Paine and Syms 2012, pp. 240-241. It had an identical platform shape to the smaller SR.N5, being rectangular with a semi-circular bow and a beam-to-length ratio of 1:1.66.Paine and Syms 2012, p. 241. The SR.N4 was powered by four Rolls-Royce Proteus turboprop engines.Paine and Syms 2012, pp. 238, 242. The Proteus engines each drove a set of diameter steerable Dowty Rotol propellers, arranged in two pairs on pylons positioned on top of the craft's roof; upon the SR.N4's introduction to service, these were the largest propellers in the world.

To protect it from bad weather, a radome made of Dacron covered the antenna. It was 160 feet (49 m) high, 210 feet (64 m) wide and weighed 30 tons. Since the satellite was not in a geosynchronous orbit like modern communication satellites, it passed overhead quickly, and the giant antenna had to be precisely steerable to track the satellite as it moved across the sky. Telstar was launched on July 10, 1962, from the Cape Canaveral Air Force Station and went into orbit at 4:46 a.m. The engineers at the Andover Earth Station would have to wait 15 hours for the satellite, travelling at a rate of 5 miles per second (8 km/s), 3,000 miles (4,800 km) above the earth to reach within their "view".

An operator in this aircraft then transmitted control signals to steerable fins fitted to the bomb. Such weapons were used increasingly by the USAF in the last few years of the Vietnam War because the political climate was increasingly intolerant of civilian casualties, and because it was possible to strike difficult targets (such as bridges) effectively with a single mission; the Thanh Hoa Bridge, for instance, was attacked repeatedly with iron bombs, to no effect, only to be dropped in one mission with PGMs. Although not as popular as the newer JDAM and JSOW weapons, or even the older laser-guided bomb systems, weapons like the AGM-62 Walleye TV guided bomb are still being used, in conjunction with the AAW-144 Data Link Pod, on US Navy F/A-18 Hornets.

The SpaceX non-geostationary orbit communications satellite constellation will operate in the high-frequency bands above 24 GHz, "where steerable earth station transmit antennas would have a wider geographic impact, and significantly lower satellite altitudes magnify the impact of aggregate interference from terrestrial transmissions". Internet traffic via a geostationary satellite has a minimum theoretical round-trip latency of at least 477 milliseconds (ms) (between user and ground gateway), but in practice, current satellites have latencies of 600 ms or more. Starlink satellites would orbit at to of the height of geostationary orbits, and thus offer more practical Earth-to-sat latencies of around 25 to 35 ms, comparable to existing cable and fiber networks. The system will use a peer-to-peer protocol claimed to be "simpler than IPv6", it will also incorporate end-to-end encryption natively.

Punjab. Notice the buffalo in its hold. Peter rehra, ਪੀਟਰ ਰੇਹੜਾ Esprit de jugaad is a homemade vehicle used in rural Punjab. It is made by assembling a diesel engine,Law frowns on it, but Peter Rehra still a hit(mostly meant for pumping water), removing the pumpset assembly from it, and joining it with a framework made steel angles and wooden planks, and finally completing it all by putting four movable wheels, two are steerable (like in all vehicles) and the two rear ones directly attached to the engine via a primitive gear- assembly.Shoot of PETER REHRA It is, of course, not meant for high- performance, but for sheer-economy, as it is easily able to carry twenty to twenty five grown-up people (plus their luggage), but mostly cannot move at more than 25 km/h.

Two-person rail-cycle draisine with four wheels A draisine () is a light auxiliary rail vehicle, driven by service personnel, equipped to transport crew and material necessary for the maintenance of railway infrastructure. The eponymous term is derived from the German inventor Baron Karl Drais, who invented his Laufmaschine (German for "running machine") in 1817, which was called Draisine in German (vélocipède or draisienne in French) by the press. It is the first reliable claim for a practically used precursor to the bicycle, basically the first commercially successful two-wheeled, steerable, human-propelled machine, nicknamed hobby-horse or dandy horse. Drais' dandy horse, called Draisine in German, whose name was inherited by the rail vehicle Later, the name draisine came to be applied only to the invention used on rails and was extended to similar vehicles, even when not human-powered.

Pancam Mast Assembly (PMA) Rock Abrasion Tool (RAT) Alpha particle X-ray spectrometer (APXS) (Courtesy NASA/JPL-Caltech) The rover has an X band low-gain and an X band high-gain antenna for communications to and from the Earth, as well as an ultra high frequency monopole antenna for relay communications. The low-gain antenna is omnidirectional, and transmits data at a low rate to Deep Space Network (DSN) antennas on Earth. The high-gain antenna is directional and steerable, and can transmit data to Earth at a higher rate. The rovers use the UHF monopole and its CE505 radio to communicate with spacecraft orbiting Mars, the Mars Odyssey and (before its failure) the Mars Global Surveyor (already more than 7.6 terabits of data were transferred using its Mars Relay antenna and Mars Orbiter Camera's memory buffer of 12 MB).

The front section, intended to contain the crew and engines, was long with a gas capacity of 9514 cu m (336,000 cu ft): the middle section was long with an intended useful load of and the rear section long with an intended load of Robinson 1973 pp.15-6 In early 1896, Zeppelin's lecture on steerable airship designs given to the Association of German Engineers (VDI) so impressed them that the VDI launched a public appeal for financial support for him. This led to a first contact with Carl Berg who supplied aluminium alloys which Zeppelin had tested, and by May 1898 they, together with Philipp Holzmann, Daimler, Max von Eyth, Carl von Linde, and Friedrich Voith, had formed the joint stock company Gesellschaft zur Förderung der Luftschiffart. Zeppelin invested 441,000 Marks, over half the total capital.

Wobble, shimmy, tank-slapper, speed wobble, and even death wobble are all words and phrases used to describe a quick (4-10 Hz) oscillation of primarily just the steerable wheel(s) of a vehicle. Initially, the rest of the vehicle remains mostly unaffected, until translated into a vehicle yaw oscillation of increasing amplitude producing loss of control. Vehicles that can experience this oscillation include motorcycles and bicycles, skateboards, and, in theory, any vehicle with a single steering pivot point and a sufficient amount of freedom of the steered wheel, including that which exists on some light aircraft with tricycle gear where instability can occur at speeds of less than 80 kmh; this does not include most automobiles. The initial instability occurs mostly at high speed and is similar to that experienced by shopping cart wheels and aircraft landing gear.

The first satellites were deployed in a circular orbit along the equator at an altitude of 8063 km (medium Earth orbit) at a velocity of approximately , each making 5 orbits a day. As of 2018, the constellation has sixteen satellites operational in orbit, after four launches of four satellites each. Due to problems with a component of the first four satellites launched, three of those four have been placed on standby for the other three, so thirteen are used operationally. Each satellite is equipped with twelve fully steerable Ka- band antennas (two beams for gateways, ten beams for remotes) that use 4.3 GHz of spectrum (2 × 216 MHz per beam) with a proposed throughput of 1.6 Gbit/s per beam (800 Mbit/s per direction), resulting in a total capacity of 16 Gbit/s per satellite.

On the other hand, the hard wood or metal front section of steerable runner sleds is far more likely to cause serious injury if it strikes a person, or if the hands are caught between the steering mechanism and a solid object in a crash. Each year, around 30,000 children in the US are injured in sledding, with one in 25 injuries requiring hospitalization. In a majority of these serious cases, young children are riding runner sleds in a prone position, and suffer hand and finger injuries when they are caught under the runners or between the sled and another object.BJC Health Care - The Ups and Downs of Sledding Safety In addition, runner sleds force the weight of the rider onto two thin runners where the pressure causes a microscopic film of snow or ice to melt as the sled passes over it.

The fully steerable dish of the QTT will allow it to observe 75% of the stars in the sky at any given time. The QTT and the Five-hundred-meter Aperture Spherical Telescope (FAST), also located in China, can both observe frequencies in the "water hole" that has traditionally been favored by scientists engaged in the Search for Extraterrestrial Intelligence (SETI), meaning that each observatory could provide follow-up observations of putative signals from extraterrestrials detected in this quiet part of the radio spectrum at the other observatory. The radio telescope site selection team considered 48 candidate locations throughout Xinjiang. The chosen site for the facility is in the foothills of the Tian Shan mountains, near Shihezi village, Banjiegou Town, about 46 km (straight-line distance) south-south-east of the Qitai county seat (Qitai Town).

Its flat four, air-cooled, Limbach L2000 engine was mounted on the wing and drove a pusher propeller, requiring the slender, rounded tailboom to be lowered from the wing, on the Bakcyl, to the bottom of the pod. The tail was similar to that of the Bakcyl, with a tall, broad fin and smaller, fabric covered rudder, together trapezoidal in profile, and a smaller, low set, fin-mounted, rectangular plan horizontal tail at the extreme end of the tailboom, its one-piece elevator aft of the rudder. The Pelikan had fixed tricycle gear with mainwheels, equipped with brakes, on arched, cantilever, fibreglass-epoxy/spring legs from the lower fuselage (though one photograph shows an additional drag strut) and a smaller, steerable nosewheel. Two airframes were built but only one flew, with the other used for stress-testing.

1919 Ford Model T Transverse leaf spring front suspension is a type of automotive front suspension, whose usage is most well known in Ford Motor Company products from 1908 to 1948 (1959 for the inexpensive Ford Popular in the UK). "Suicide front axle" is a term that has been used for it. The configuration consists of a one-piece axle (solid front axle), to the ends of which the steerable front wheels are mounted. The axle receives its vertical and transverse support from a transverse leaf spring (leaf springs were often used for support in more than one direction), and its longitudinal support from fore-aft links sometimes called "radius rods" which are attached (via pivots) to the ends of the axle at their forward end and to the sides of the chassis (again via pivots) at their aft end.

The favorable location of Millstone Hill at sub-auroral latitudes combined with the great operational range afforded by the steerable antenna permit observations over a latitude span encompassing the region between the polar cap and the near-equatorial ionosphere. Since 1982 the Haystack Observatory Atmospheric Sciences Group has been supported for operating the Millstone Hill research radar as a part of the incoherent scatter radar chain and for associated studies of the auroral and sub-auroral ionosphere and thermosphere. The meridional radar chain extends from Sondrestrom Upper Atmospheric Research Facility in Kangerlussuaq, Greenland through Millstone Hill at mid-latitudes, beyond Arecibo at low latitudes, to the Jicamarca facility at the magnetic equator in Peru. The radar chain forms an integral part of the NSF-supported CEDAR (Coupling, Energetics, and Dynamics of Atmospheric Regions) observing network and Millstone Hill observations and analysis have contributed extensively to the successes of the CEDAR initiative.

Turksat Satellite Systems continued progress regarding the need of new satellites having multiple channels, larger coverage, and backup capability like the other satellite operator satellites in the international market. To serve with a larger coverage area for resident customers and to compete with the other satellite operators in the literal sense, the new satellite would be located at the same position with Turksat 1C. Türk Telekom set up a joint venture company with Aérospatiale (merged by Alcatel Space, then Thales Alenia Space), called EurasiaSat, which would be in charge of purchasing a new-generation satellite named Turksat 2A (also known as Eurasiasat 1). Turksat 2A started commercial service on February 1, 2001, with the same 42°E location as Turksat 1C. Turksat 2A satellite carries a payload of 34 high-powered transponders consisting of 22 33 MHz fixed-beam transponders and 12 36 MHz transponders with two steerable beams.

The steerable nose wheel retracted to the rear, while the main gear retracted forward. Illustration of Yakovlev Yak-141 The top-mounted wing was similar to that of the Yakovlev Yak-36, though the outer panel swept back, and could be folded up for shipboard storage. The main engine was served by four side-mounted ducts as well as a row of large louvers along the upper surface to allow air to enter the engine during full power hovering. This engine was the R-79V-300, a two-shaft augmented turbofan with a bypass ratio of 1. Maximum thrust was 14,000 kg (30,864 lb). The rear nozzle could rotate from 0 degrees to 95 degrees for VTOL landing and hovering. The two lift engines were the RD-41 design, a simple single-shaft engine made mostly of titanium. Each had a thrust of 4,100 kg (9,040 lb).

Steerable ducted fans on a Skyship 600 provide thrust, limited direction control, and also serve to inflate the ballonets to maintain the necessary overpressure Since blimps keep their shape with internal overpressure, typically the only solid parts are the passenger car (gondola) and the tail fins. A non-rigid airship that uses heated air instead of a light gas (such as helium) as a lifting medium is called a hot-air airship (sometimes there are battens near the bow, which assist with higher forces there from a mooring attachment or from the greater aerodynamic pressures there). Volume changes of the lifting gas due to temperature changes or to changes of altitude are compensated for by pumping air into internal ballonets (air bags) to maintain the overpressure. Without sufficient overpressure, the blimp loses its ability to be steered and is slowed due to increased drag and distortion.

The Experimental and Development Department, as part of the IBA's Engineering Division, was responsible for much leading edge research into broadcasting technology as well as being responsible for the design and manufacture of specialist equipment that could not be procured from commercial manufacturers. In particular, the IBA's E&D; Department developed SABRE (Steerable Adaptable Broadcast Receiving Equipment) that enabled mainland broadcast television channels to be received for re-broadcasting in the Channel Islands. During the early 1980s, the E&D; Department designed and manufactured the specialised broadcast receiving and monitoring equipment used to build the national broadcast network for Channel Four. Subsequently, E&D;'s engineers proposed a system of analogue television encoding known as MAC (Multiplexed Analogue Component) to provide a standard for the forthcoming satellite television broadcasts that was more robust than an extension of the existing PAL system used for terrestrial broadcasts.

SpaceX payload fairing before the launch of thumb During the first six decades of spaceflight, payload fairings were expended by atmospheric reentry and allowed to drop into the ocean as debris/flotsam. In 2018, SpaceX began flight test experiments with fairings descending from sub-orbital trajectories above the atmosphere on its Falcon 9 rockets. As a part of the SES-10 mission in March 2017, SpaceX successfully performed a controlled landing of the payload fairing into the ocean for the first time. SpaceX was able to recover the fairing half from the water after it landed, aided by attitude-control thrusters and a steerable parachute, gently on water. At the SES-10 news conference, the company announced its intent to land the fairings on a dry flexible structure, jokingly described by Elon Musk as a "floating bouncy castle", with the goal of reusing the fairings.

Freya was often used in concert with the primary German gun laying radar, Würzburg Riese ("Würzburg Giant"); the Freya finding targets at long distances and then "handing them over" to the shorter-ranged Würzburgs for tracking. Later in the war, Freya operated in the band from (120 to 130 MHz), with a pulse width of three microseconds, a peak power output of 15 to 20 kW, and a pulse repetition frequency of 500 Hz. It had a maximum range of only , making it inferior to Chain Home. Furthermore, it could not accurately determine altitude, but it was a fully steerable and semi-mobile system. Würzburg-Riese, date and place unknown Freya was first successfully used on December 18, 1939 when two stations detected an approaching daytime raid on Wilhelmshaven by 22 RAF Vickers Wellington bombers at a range of 113 km and guided fighter planes toward them via radio.

Payload fairings have traditionally been expendable, where they have either burned up in the atmosphere or were destroyed upon impacting the ocean. As early as mid-2015, Musk hinted that SpaceX might be working on fairing reusability, following the discovery of wreckage of an unidentified Falcon 9 launch vehicle section off the coast of The Bahamas, and was subsequently confirmed by SpaceX to be a component of a payload fairing that had washed ashore. By April 2016, SpaceX had publicly announced Falcon 9 fairing recovery as an objective. The cost of the fairing is about $6 million per launch, which accounts for approximately ten percent of the overall launch costs. In March 2017, as part of the SES-10 mission, SpaceX for the first time performed a controlled landing of the payload fairing and successfully recovered a fairing half, aided by attitude-control thrusters and a steerable parachute, helping it glide towards a gentle touchdown on water.

The U.S. Congress considered this too expensive for an interim solution. A quick, inexpensive upgrade using the Low Altitude Navigation and Targeting Infrared for Night (LANTIRN) targeting pod was devised. The LANTIRN pod provided the F-14 with a forward-looking infrared (FLIR) camera for night operations and a laser target designator to direct laser-guided bombs (LGB).Gobel, Greg. "Bombcat / Tomcat In Service 1992:2005". Vectorsite.net, 1 November 2006. Retrieved: 8 December 2009. Although LANTIRN is traditionally a two-pod system, an AN/AAQ-13 navigation pod with terrain-following radar and a wide-angle FLIR, along with an AN/AAQ-14 targeting pod with a steerable FLIR and a laser target designator, the decision was made to only use the targeting pod. The Tomcat's LANTIRN pod was altered and improved over the baseline configuration, such as a Global Positioning System / Inertial Navigation System (GPS-INS) capability to allow an F-14 to accurately locate itself.

The linear motors and steerable axles used in Innovia Metro trains are relatively rare, although similar Japanese designed linear motor propulsion technologies are also used on a number of subway lines in East Asia, such as the Nagahori Tsurumi-ryokuchi Line, Toei Ōedo Line and Guangzhou Metro Line 5. However, the Innovia Metro system has a number of competitors in the field of automated light metros, including the VAL technology developed by Matra for the Lille Metro in France (and now owned by Siemens) and the Meteor technology used by Paris Métro Line 14 (which is built to high-capacity, full metro standards). Furthermore, the CITYFLO and SelTrac signaling technologies are not specific to the Innovia Metro, but can also equip most conventional railway lines regardless of propulsion technology or carrying capacity. Innovia Metro lines are designed to run on elevated structures, and indeed the systems that use these trains include such sections, with most being predominantly elevated.

RC Scale model aircraft can be of any type of steerable airship lighter-than-air (LTA) aviation craft, or more normally, of the heavier-than-air fixed wing glider/sailplane, fixed- wing single or multi-engine aircraft, or rotary-wing aircraft such as autogyros or helicopters. Full-scale aircraft designs from every era of aviation, from the "Pioneer Era" and World War I's start, through to the 21st century, have been modeled as radio-control scale model aircraft. Builders of RC Scale aircraft can enjoy the challenge of creating a controllable, miniature aircraft that merely "looks" like the full scale original in the air with no "fine details", such as a detailed cockpit, or seriously replicate many operable features of a selected full scale aircraft design, even down to having operable cable-connected flight control surfaces, illuminated navigation lighting on the aircraft's exterior, realistically retracting landing gear, etc. if the full-sized aircraft possessed such features as part of its design.

Shape-memory alloys are applied in medicine, for example, as fixation devices for osteotomies in orthopaedic surgery, as the actuator in surgical tools; active steerable surgical needles for minimally invasive percutaneous cancer interventions in the surgical procedures such as biopsy and brachytherapy, in dental braces to exert constant tooth-moving forces on the teeth, in Capsule Endoscopy they can be used as a trigger for biopsy action. The late 1980s saw the commercial introduction of Nitinol as an enabling technology in a number of minimally invasive endovascular medical applications. While more costly than stainless steel, the self expanding properties of Nitinol alloys manufactured to BTR (Body Temperature Response), have provided an attractive alternative to balloon expandable devices in stent grafts where it gives the ability to adapt to the shape of certain blood vessels when exposed to body temperature. On average, of all peripheral vascular stents currently available on the worldwide market are manufactured with Nitinol.

Tractors can be generally classified by number of axles or wheels, with main categories of two-wheel tractors (single-axle tractors) and four-wheel tractors (two-axle tractors); more axles are possible but uncommon. Among four-wheel tractors (two-axle tractors), most are two- wheel drive (usually at the rear); but many are two-wheel drive with front wheel assist, four-wheel drive (often with articulated steering), or track tractors (with steel or rubber tracks). Volvo T25, 1956, gasoline tractor The classic farm tractor is a simple open vehicle, with two very large driving wheels on an axle below and slightly behind a single seat (the seat and steering wheel consequently are in the center), and the engine in front of the driver, with two steerable wheels below the engine compartment. This basic design has remained unchanged for a number of years, but enclosed cabs are fitted on almost all modern models, for reasons of operator safety and comfort.

It has been suggested that the impetus for NHTSA's seeming preoccupation with market control rather than vehicular safety performance is a result of overt market protections such as tariffs and local-content laws having become politically unpopular due to the increasing popularity of free trade, thus driving industry to adopt less visible forms of trade restrictions in the form of technical regulations different from those outside the United States.Crouching Tariff, Hidden Trade Barrier? - DrivingVisionNews An example of the market-control effects of NHTSA's regulatory protocol is found in the agency's 1974 banning of the Citroën SM automobile, which contemporary journalists hailed as one of the safest vehicles available at the time. NHTSA disapproved the SM due to its steerable headlamps which were not of the sealed beam design mandatory in the U.S., and its height adjustable suspension, which made compliance with the 1973 bumper requirements impossible; the bumper regulation was intended to control the costs resulting from low speed collisions, not enhance occupant safety.

A rotary steerable system (RSS) is a form of drilling technology used in directional drilling. It employs the use of specialized downhole equipment to replace conventional directional tools such as mud motors. They are generally programmed by the measurement while drilling (MWD) engineer or directional driller who transmits commands using surface equipment (typically using either pressure fluctuations in the mud column or variations in the drill string rotation) which the tool responds to, and gradually steers into the desired direction. In other words, a tool designed to drill directionally with continuous rotation from the surface, eliminating the need to "slide" a mud motor. The first known patent application is from Christopher G. Cross in 1873 for "Drills for Boring Artesian Wells",United States Patent and Trademark Office followed in 1884 by the brothers Morris and Clarence Baker for a "Machine for Operating Drills"United States Patent and Trademark Office The methods used to direct the well path fall into two broad categories, these being “push-the-bit” or “point-the-bit”.

1986 operator and AN/FPS-115 console. Fixed-reflector radars with mechanically-scanned beams such as the 1955 GE AN/FPS-17 Fixed Ground Radar and 1961 RCA AN/FPS-50 Radar Set were deployed for missile tracking, and the USAF tests of modified AN/FPS-35 mechanical radars at Virginia and Pennsylvania SAGE radar stations had "marginal ability" to detect Cape Canaveral missiles in summer 1962. A Falling Leaves mechanical radar in New Jersey built for BMEWS successfully tracked a missile during the October 1962 Cuban Missile Crisis, and "an AN/FPS-85 long-range phased array (Passive electronically scanned array) radar was constructed at Eglin AFB" Site C-6, Florida beginning on 29 October 1962 (the Bendix Radio Division FPS-85 contract had been signed 2 April 1962). Early military phased array radars were also deployed for testing: Bendix AN/FPS-46 Electronically Steerable Array Radar (ESAR) at Towson, MD (powered up in November 1960), White Sands' Multi-function Array Radar (1963), and the Kwajalein Missile Site Radar (1967).

The three-unit landing gear retracted into the fuselage; the twin-wheel nose gear was steerable and stressed for catapult- assisted take-offs. VA-147 was the first operational USN A-7 squadron, in 1967. To achieve the required range, initial versions of the A-7 were powered by a single Pratt & Whitney TF30-P-6 turbofan engine, which produced 11,345 lbf (50.5 kN) of thrust. It had replaced the afterburner-equipped Pratt & Whitney J57-P-20A turbojet engine of the F-8. The same engine had also powered several other combat aircraft of the era, including the General Dynamics F-111 Aardvark and early Grumman F-14 Tomcats. The TF30-P-6 did not require an afterburner for its subsonic role. Later versions of the A-7 used different engines; according to Gunston and Gilchrist, this was largely due to production difficulties in keeping up with numerous military and civil demands. These new powerplants included the more powerful Pratt & Whitney TF30-8 and the Allison TF41-A-2 engines, a licensed model of the Rolls-Royce Spey engine.

CSX began receiving an order of 200 ES44ACs (referred to by CSX as the ES44AH) in December 2007. The A is for A.C power The "H" in the class CW44AH and ES44AH units refers to the HTE ("high tractive effort") adhesion-management software with which those units are equipped. The reason CSXT has assigned specific classes to units equipped with that software is that the software allows the units to have increased tonnage ratings and is in reference to a combination of subsystems that produce high levels of tractive effort at low speeds. In order to be classified as an "AH" by CSX, a locomotive has to have not only an increased nominal weight (currently to ), but also (1) steerable trucks, (2) TM3 adhesion control software, (3) software that extends to from the maximum amount of tractive effort that each traction motor is permitted to produce, and (4) GE's Rail Cleaner, which directs high-pressure air onto the rails in front of the sand nozzles forward of axle number one.

Following atmospheric re-entry, the traditional capsule-like spacecraft from the Mercury, Gemini, and Apollo series had very little control over where they landed. A steerable spacecraft with wings could significantly extend its landing envelope. However, the vehicle's wings would have to be designed to withstand the dynamic and thermal stresses of both re-entry and hypersonic flight. A proposed solution eliminated wings altogether: design the fuselage body itself to produce lift. NASA's refinements of the lifting body concept began in 1962 with R. Dale Reed of NASA's Armstrong Flight Research Center. The first full-size model to come out of Reed's program was the NASA M2-F1, an unpowered craft made of wood. Initial tests were performed by towing the M2-F1 along a dry lakebed at Edwards Air Force Base California, behind a modified Pontiac Catalina.Classical Pontiac and NASA Later the craft was towed behind a C-47 and released. Since the M2-F1 was a glider, a small rocket motor was added in order to extend the landing envelope.

Salyut 6, launched on a Proton 8K82K rocket on 29 September 1977, marked the switch from engineering development stations to routine operations, and united the most effective elements from each of the previous stations. Its navigation system, made up of the Delta semi-automatic computer to depict the station's orbit and the Kaskad system to control its orientation, was based on that used on Salyut 4, as was its power system, which consisted of a trio of steerable solar panels, together producing a peak of 4 kilowatts of power over 51 m². The station's thermal regulation systems, which made use of a sophisticated arrangement of insulation and radiators, was also derived from that used on Salyut 4. In addition, Salyut 6 made use of environmental systems first used on Salyut 3, and controlled its orientation using gyrodynes first tested on that station. Progress (P) and Soyuz (F) spacecraft The most important feature on Salyut 6, however, was the addition of a second docking port on the aft end of the station, which allowed two spacecraft to be docked at once.

The satellite provides two broadcast beams, each with horizontal and vertical polarisation, across two footprints - 2B North (covering central Europe and Scandinavia) and 2B South (covering Central Europe and the Iberian peninsula and Canary Islands). While at 28.2°E, TV signals could be received with a 43 cm dish across the majority of the British Isles with a 60 cm dish required in the extreme north and west, although the official footprint maps now show a 60 cm dish as required across all of western Europe. At 28.2°E 17 transponders on Astra 2B were used by BSkyB to provide the Sky Digital TV services of standard and high definition TV and digital radio. Astra 2B could also provide backup capacity, substituting for one or more transponders across the whole 10.70-12.75 GHz range used by Astra satellites in the Astra 19.2°E and Astra 28.2°E orbital positions. A third, steerable beam provides 8 transponders in the 12.50-12.75 GHz range for Internet and telecommunications services in West Africa.

International interest: French artist's impression of the projected launch The Arctic ambitions of Sweden were still unrealized in the late 19th century, while neighboring and politically subordinate Norway was a world power in Arctic exploration through such pioneers as Fridtjof Nansen.Lundström, pp. 19–44. The Swedish political and scientific elite were eager to see Sweden take that lead among the Scandinavian countries which seemed her due, and Andrée, a persuasive speaker and fundraiser, found it easy to gain support for his ideas. At a lecture in 1895 for the Royal Swedish Academy of Sciences, Andrée thrilled the audience of geographers and meteorologists; a polar exploration balloon, he explained, would need to fulfill four conditions: # It must have enough lifting power to carry three people and all their scientific equipment, advanced cameras for aerial photography, provisions for four months, and ballast, altogether about # It must retain the gas well enough to stay aloft for 30 days # The hydrogen gas must be manufactured, and the balloon filled, at the Arctic launch site # It must be at least somewhat steerable Andrée gave a glowingly optimistic account of the ease with which these requirements could be met.

The AAC fitted it with an American Kinner engine. Following on the heels of a boom in the aviation industry in America – largely attributed to Charles Lindbergh’s flight in 1927 – it was among the few foreign designs to be manufactured in the United States under Approved Type Certificates (ATCs) and, at $7,300, was also the first low-priced amphibious aircraft on the U.S. market. The size and price of the vehicle appealed to recreational aviators, despite its difficult handling. On water, the plane lacked a rudder; on ground, the plane only had a non-steerable tail skid (that is: no conventional brakes); and in the air, when the wheels were extended, the added drag complicated the steering. Thirty-six S-56s were built under ATC A-287, which was awarded on 4 January 1930. The S-56 became the first plane used by the New York City Police Department, which used it to enforce flying regulations, assist with sea rescues, and to chase rum-runners during the Prohibition era. A follow-up design, the S-56B, proved even more successful. ATC A-336, for the S-56B design, was awarded on 11 July 1930.

Algonquin Radio Observatory, Lake Traverse, Ont., Canada A second telescope, identical to the one at ARO, was later installed at the Dominion Radio Astrophysical Observatory (DRAO) in Penticton, British Columbia as a backup. Another solar instrument patterned on a different Goth Hill device followed, this one consisting of a series of thirty-two 10 ft (3 m) parabolic collectors connected to a common 700 ft (215 m) long waveguide. Using phased array techniques this instrument could image portions of the Sun's disk, compared to the single-dish instrument which saw the sun as a single unresolved "dot". The new instrument was up and running in 1966, adding to Covington's study of the sun by directly imaging the radio signal from sunspots and filaments. In 1961, the site was selected by the National Research Council of Canada as suitable for the construction of a fully steerable antenna.National Research Council of Canada: Proposed 120ft Telescope, Freeman Fox and Partners, Drawing 384, March 1961 By 1962, plans showed that the main instrument had grown to a antenna; construction of this commenced in 1964. The new telescope opened for operation in May 1966. left The 46 m Thoth telescope (left) and 11m telescope (right) viewed from the entrance road at the Algonquin Radio Observatory.

The fin and rudder are swept. The straight tapered tailplane is set on top of the fuselage, the port elevator carrying a trim tab. The Bulgarian company ACS started producing the Skyleader 600 at the state owned TEREM-Letets aircraft factory in Sofia in July 2015 under a licence agreement. The original Sova/Skyleader 150 has staggered side- by-side configuration seating with the starboard seat 200 mm (8 in) aft of the other, but a widened fuselage allows the Skyleader 200 to have true side-by- side seating. The earlier version has a forward-hinged canopy with fixed rear transparencies; the Skyleader 200 has a single-piece canopy. Both these variants normally have an electrically actuated tricycle undercarriage with a steerable nosewheel, though a fixed version is an option and is standard on the later Skyleader 500 and 600 variants. The standard engine for the 150/200 variants is a 60 kW (80 hp) Rotax 912UL, though the more powerful Rotax 912ULS or Rotax 914 can be fitted, all driving a choice of two-blade propellers. The 500/600 variants can also use the Rotax 912 UL or Rotax 912S; the Jabiru 2200 or 3300 engines may also be fitted.

The empennage is of sheet metal. The two-spar wings are of all-metal construction. The tricycle landing gear is fixed, with a steerable nosewheel. Designed for aerobatics instruction, it was certified to +6.0 and -4.0 limit maneuvering load factors, and was equipped with full inverted fuel and oil systems, permitting extended inverted flight. The Z 42 is powered by a Walter inverted six-cylinder engine rated at 134 kW (180 hp). The revised Zlín Z 42M flew in November 1972, with a revised tail taken from the Z 43, and a Constant speed propeller replacing the variable pitch propeller (where the propeller pitch is controlled by the pilot) of the original Z 42. When early Z 42s were refitted with the new propeller, they were redesignated Z 42 MU. Zlín Z-142 Development continued, with the Zlín Z 142, featuring a slightly enlarged two-seat airframe based on that of the Z 42 and the more powerful (157 kW (210 hp)) Walter (now LOM) M 337 fuel-injected inverted six-cylinder, supercharged air- cooled engine of the Z 43 replacing the unsupercharged LOM M137 engine of the Z 42. The prototype Z-142 first flew on 29 December 1978.
