Pintle and gudgeon rudder system. Part 2 is the pintle, and part 3 is the gudgeon. Several examples of pintles as part of door hinges A pintle is a pin or bolt, usually inserted into a gudgeon, which is used as part of a pivot or hinge. Other applications include pintle and lunette ring for towing, and pintle pins securing casters in furniture.

In pintle engines that do not require throttling, the pintle is fixed in place, and propellant valves for startup and shutdown are placed somewhere else. A movable pintle allows for throttleability, and, if the moving part is the sleeve, the pintle itself can act as the propellant valve. This is called a Face Shutoff pintle. A fast- moving sleeve allows for the engine to be operated in pulses, and this is usually done in pintle-based RCS thrusters and missile divert thrusters.

Brick structures can employ a similar embedded pintle, or a surface mounted pintle. Storm type strap hinges are typically in Europe, American examples are often tapered. Surface mounting seems the simpler approach. We've used a modified jamb pintle on a custom installation where a full board shutter allowed strap hinges to be installed high enough on the shutter to cover the pintle in the open position.

Essentially, the pintle is a bracket with a cylindrical bottom and a cradle for the gun on top; the cylindrical bottom fits into a hole in the tripod while the cradle holds the gun. In furniture, a pintle is usually fitted to a caster; the pintle is then inserted into a base, fixing the caster to that base. In rocketry, a pintle injector uses a single-feed fuel injector rather than the hundreds of smaller holes used in a typical rocket engine."Pintle Injector Rocket Engines", accessed 2011-02-04.

The center pintle carriage gave the gun a 360° traverse and was stronger for guns firing at high angles because the pintle, the strongest part of the carriage, would have been under the breech when the gun was fired at high angles. The casemate carriage was designed to fire from casemates which were chambers in permanent fortifications. The carriage was essentially a front-pintle design, with the pintle fixed in the masonry in front of the chassis and below the guns embrasure. A "tongue" connected the chassis to the pintle.

In a variant of the Face Shutoff pintle, the pintle itself is hydraulically actuated by the fuel via a pilot valve, and no extra valves are required between the engine and tanks. This is called an FSO (Face Shutoff Only) pintle. In some variants the pintle has grooves or orifices cut into it to produce radial jets in the flow of propellant B, this allows for extra unburned fuel to impinge on the walls of the combustion chamber, and provide fuel film cooling. The pintle pictured here is of this type.

The field artillery limber assumed its archetypal form – two wheels, an ammunition chest, a pintle hook at the rear, and a central pole with horses harnessed on either side. The artillery piece had an iron ring (lunette) at the end of the trail. To move the piece, the lunette was dropped over the pintle hook (which resembles a modern trailer hitch). The connection was secured by inserting a pintle hook key into the pintle.

Throttleability can be obtained either by placing valves before the injector, or by moving the inner pintle or outer sleeve. Many people have experienced throttleable pintle sprayers in the form of standard garden hose-end sprayers. A pintle injector is shown during a cold flow test. The inner flow path is active.

One part on the body of the cubicle, one part on the door and the third part is the pintle. In transportation, a pintle hitch is a type of tow hitch that uses a tow ring configuration to secure to a hook or a ball combination for the purpose of towing an unpowered vehicle."Pintle Hooks and Combination Hitches", accessed 2011-02-04."Pintle Hitch, Hooks, Mounts" , accessed 2013-01-22 As a weapon mount, a pintle mount is used with machine guns as the mounting hardware that mates the machine gun to a vehicle or tripod.

Pintle-based engines were first used on a crewed spacecraft during the Apollo Program in the Lunar Excursion Module's Descent Propulsion System, however, it was not until October 1972 that the design was made public. and was granted to the pintle injector inventor Gerard W. Elverum Jr. Pintle injectors are currently used in SpaceX's Merlin engine family.

In the early 2000s TRW continued development of large LOX/LH2 pintle engines, and test-fired the TR-106 at NASA's John C. Stennis Space Center. This was a 650,000 lbf (2,892,000 N) engine, a 16:1 scale-up from the largest previous LOX/LH2 pintle engine and about a 3:1 scale-up from the largest previous pintle engine ever tested. This injector's pintle diameter was , by far the largest built to date. In 2002 the larger TR-107 was designed.

The shutter may sit proud on the casing as drawn, or the shutter sits within the casing with its thickness exceeding the rabbet depth - in any case the hinge and pintle will each mount at a different distance from the face of the structure. The offset can no longer be evenly divided between the hinge and the pintle. Lay a hinge or pintle on a flat surface. Call the distance from that surface to the middle of the hinge barrel or the pintle pin the Standoff.

It's also common in the south of Europe - France, Italy, and Austria. It's a very clean installation and allows the shutter to sit almost fully parallel to the structure. The European structures are typically stucco coated, with a drive type pintle built diagonally into the masonry prior to stucco finish. A lag screw pintle can be substituted for the drive pintle.

This pintle was a flat plate of about two inches high and notched to one half of its height and formed to a female barrel. Holes were punched in the side of the pintle and it was screwed directly to the side of the window before the window was installed on the structure. The strap hinges were modified to match the new pintles… the hinge was of the same width as the pintle and notched to one half of its height. A pin to mate with the female pintle was welded in the hinge.

Pintle injectors began as early laboratory experimental apparatuses, used by Caltech's Jet Propulsion Laboratory in the mid-1950s, to study the mixing and combustion reaction times of hypergolic liquid propellants. The pintle injector was reduced to practice and developed by Space Technology Laboratories (STL), then a division of Ramo-Wooldridge Corp., later TRW, starting in 1960. There have been pintle-based engines built ranging from a few newtons of thrust up to several millions, and the pintle design has been tested with all the common and many exotic propellant combinations, including gelled propellants.

Gudgeon with a pintle A gudgeon is a socket-like, cylindrical (i.e., female) fitting attached to one component to enable a pivoting or hinging connection to a second component. The second component carries a pintle fitting, the male counterpart to the gudgeon, enabling an interpivoting connection that can be easily separated. Designs that may use gudgeon and pintle connections include hinges, shutters and boat rudders.

This value is the standoff for the hinge. (1½"). Add the thickness of the shutter to the hinge standoff (1"+1½"=2½"). This is the standoff for the pintle (2½"). Add the hinge and pintle standoffs to verify (1½"+2⅓"=4"=offset=okay).

Two haulm rollers combined with a 1.65 m pintle belt guarantee an efficient haulm removal.

The forward-raked main gear struts on the Republic P-47 partly used "pintle angling" to allow them to clear the forward wingspar during retraction. Pintle is also a common term used in the design of aircraft landing gears. It describes the attachment point between the landing gear structure and the aircraft structure. The pintle is the bolt around which the landing gear rotates when it is extended/retracted into/out of the aircraft.

A pintle injector is shown during a cold flow test. The outer flow path is active.

A lunette ring is a type of trailer hitch that works in combination with a pintle hook on the tow vehicle. A pintle hook and lunette ring makes a more secure coupling, desirable on rough terrain, compared to ball-type trailer hitches. It is commonly seen in towing applications in agriculture, industry and the military. The clearance between the lunette and pintle allows for more relative motion between the trailer and tow vehicle than a ball coupling does.

Compared to some injector designs, pintle injectors allow greater throttling of bipropellant flow rates, although throttling rocket engines in general is still very difficult. If only one central injector is used, the mass flow inside the combustion chamber will have two main recirculation zones which decrease acoustic instability without necessarily requiring acoustic cavities or baffles. The pintle injector design can deliver high combustion efficiency (typically 96–99%). A pintle injector is shown during a cold flow test.

In ground use, it was normally mounted on single or twin pintle mounts on various jeeps and trucks.

Fuel in red, oxidizer in blueThe pintle injector is a type of propellant injector for a bipropellant rocket engine. Like any other injector, its purpose is to ensure appropriate flow rate and intermixing of the propellants as they are forcibly injected under high pressure into the combustion chamber, so that an efficient and controlled combustion process can happen. A pintle- based rocket engine can have a greater throttling range than one based on regular injectors, and will very rarely present acoustic combustion instabilities, because a pintle injector tends to create a self-stabilizing flow pattern. Therefore, pintle-based engines are specially suitable for applications that require deep, fast, and safe throttling, such as landers.

A pintle-mounted FN MAG-58 7.62×51mm NATO light machine-gun could be fitted on the top roof.

The hinge standoff is the distance from the face of the shutter to the center-line of the hinge barrel. Adding the pintle standoff to the hinge standoff results in the total offset. Standoff is very important. Virtually all commercially available shutter hardware is provided with matching standoff on the hinge and pintle.

Here the shutter is fitted to the dimensions of the masonry opening. The pintle is embedded or surface mounted to the structure itself. The pintle pin is positioned on the outside corner of the masonry. I've seen this approach on quite a few brick structures, especially post-civil war commercial multi-story buildings.

The M60B's advantage over pintle-mounted variants was that it had a wider and much less restricted field of fire.

My favorite surface approach is to use a notched hinge with a matching pintle. A 405 lift-off will work.

Pintle/gudgeon sets have many applications, for example: in sailing to hold the rudder onto the boat; in transportation a pincer-type device clamps through a lunette ring on the tongue of a trailer; in controllable solid rocket motors a plug moves into and out of the motor throat to control thrust. In electrical cubicle manufacture, a pintle hinge is a hinge with fixed and moving parts. The hinge has a pin "pintle" and can be both external and internal. The most common type consists of three parts.

A disadvantage is that the shutters must be matched closely to the inside dimension of the casing and the shutter rabbet should match the thickness of the shutters. Any surface mounted hinge and pintle can be used - assuming there is sufficient width to the casing to accept the pintle. The hinge has a minimal standoff, and the pintle would have the same, matching standoff. Together an offset of 1–1½ inches will hold the shutter that same distance from the structure, and not quite parallel to the wall.

The Merlin engine remained the only pintle injector engine in operation, used for all SpaceX Falcon 9 and Falcon Heavy flights.

Prime movers were used to tow field artillery pieces, they also transported gun crews, equipment, and ammunition. They had a pintle hitch at the rear for towing up to . Another pintle at the front could be used to emplace the piece. A mid-mounted winch had a centered cable drum and a capstan on the right side.

FV430 vehicles, if armed, tend to have a pintle-mounted L7 GPMG. There are two three-barrel smoke dischargers at the front.

Rodman guns were mounted on three types of carriages—a front- pintle barbette carriage, a center-pintle barbette carriage, and a casemate carriage. All of these carriages were made of wrought iron. All three types of carriage were similar in design, having an upper carriage that was placed on a two-rail chassis. The gun and upper carriage recoiled along the chassis.

Limber (left) and gun, ca. 1461 As artillery pieces developed trunnions and were placed on carriages featuring two wheels and a trail, a limber was devised. This was a simple cart with a pintle. When the piece was to be towed, it was raised over the limber and then lowered, with the pintle fitting into a hole in the trail.

The lunette is the towing pintle that allows the weapon to be connected to the vehicle. When towing, vehicle has a fixed or seized tow pintle; remove the lock plate located under the lunette. The drawbar has two positions: lowered for travel and raised for firing. There are two lifting brackets to connect slings to when the howitzer is being lifted by helicopter.

It was similar to the NM-1 and NM-2 except for: front pintle for positioning artillery pieces, arched bumper (front pintle under the arche), smaller brush guard, side lights on mudguards, towing hooks on bumper deleted, radiator shell with Mack nameplate. There was no NM-4, the prototype NN-2 did not go into production. The NM-5 and NM-6 had a soft top cab with folding windscreen.

50 caliber heavy machine gun is mounted in a manually-operated pintle on the commander's hatch. Power is provided by a Detroit Diesel 6V-92TIA diesel developing 550 hp.

The goal of the development was to produce a large, low-cost, easy-to-manufacture booster engine. The design used a single element coaxial pintle injector, a robust type of injector. It also used ablative cooling of the combustion chamber and nozzle instead of the more costly to manufacture regenerative cooling. The use of the pintle injector allows the engine thrust to be widely throttleable, as was the case for the lunar module descent engine.

This section through an ED nozzle clearly shows the pintle. In this example the outer wall appears similar to the internal contour of a bell nozzle. It appears much like a standard bell nozzle, but at the throat is a 'centrebody' or 'pintle' which deflects the flow towards the walls. The exhaust gas flows past this in a more outward direction than in standard bell nozzles while expanding before being turned towards the exit.

Sitting proud on the casing, the shutters simply allowed the house to heave and settle behind them. This flush casing construction would seem common contemporary construction. A strap hinge with a zero offset and an angle pintle matched to the thickness of the shutter will serve in every case. The shutter is removed from the face of the casing by the thickness of the shutter plus the diameter of the pintle pin.

Most later variations do away with the full-length stock—especially more modern models—and have mounting hardware fixed to the gun to allow them to be fitted to a pintle.

Casters may be fixed to roll along a straight line path, or mounted on a pivot or pintle such that the wheel will automatically align itself to the direction of travel.

A supplementary M240G 7.62mm machine gun can be pintle-mounted at the vehicle commander's station in the turret. The LAV-25 is fully amphibious with a maximum of 3 minutes preparation.

In former Eastern bloc nations, the KPV, PKT and NSV machine guns are common options. In "open top" mounts the gunner sticks out of the vehicle and operates a gun on a pintle or ring mount. A ring mount allows the gun to traverse 360 degrees, a pintle mount has a limited field of fire. It can be preferable to an enclosed gunner because it allows a greater field of view and communication using shouts and hand signals.

As part of the Air Force Brilliant Pebbles program, TRW developed a very small 5 lbf (22 N) N2O4/hydrazine thruster using a pintle injector. This radiatively-cooled engine weighed 0.3 lb (135 grams) and was successfully tested in August 1993, delivering over 300 seconds Isp with a 150:1 nozzle expansion ratio. The pintle diameter was (1.6764 mm) and scanning electron microscopy was needed to verify the dimensions on the ± (0.0762 mm ±0.00762 mm) radial metering orifices.

Armament consists of a pintle-mounted GPMG and multi-barrelled smoke grenade dischargers. The back of the vehicle is designed to be extended by an attached tent to form a briefing area.

On ships, vehicles and aircraft machine guns are usually mounted on a pintle mount – basically a steel post that is connected to the frame or body. Tripod and pintle mounts are usually used with spade grips. The last major mounting type is one that is disconnected from humans, as part of an armament system, such as a tank coaxial or part of an aircraft's armament. These are usually electrically fired and have complex sighting systems, for example, the US Helicopter Armament Subsystems.

The M20 truck had a riveted ladder frame with three beam axles, the front on leaf springs, the rear tandem on leaf springs with locating arms. The wheelbase was , measured from the centerline of the front axle to the centerline of rear bogie. A pintle hitch of capacity was mounted on the rear frame crossmember; another pintle hitch was mounted on the front crossmember for positioning the trailer. All models had Budd split rim disc wheels with 12.20×20-20” tires.

Another view, showing more clearly how fuel and oxidizer flow.A pintle injector is a type of coaxial injector. It consists of two concentric tubes and a central protrusion. Propellant A (usually the oxidizer, represented with blue in the image) flows through an outer tube, coming out as a cylindrical stream, while propellant B (usually the fuel, represented with red in the image) flows within an inner tube and impinges on a central pintle-shaped protrusion, (similar in shape to a poppet valve like those found on four-stroke engines), spraying out in a broad cone or a flat sheet that intersects the cylindrical stream of propellant A. In the typical pintle-based engine design, only a single central injector is used, differing from "showerhead" injector plates which use multiple parallel injector ports.

There are many forms of tow hitch, including a ball hitch, tow bar, pintle and lunette ring, three-point, fifth wheel, coupling, and drawbar, among others. The tow-ball is popular for lighter loads, readily allowing swivelling and articulation of a trailer. A tow pin and jaw with a trailer loop are often used for large or agricultural vehicles where slack in the pivot pin allows the same movements. A pintle and lunette is a very heavy duty hitching combination used in construction and the military.

Near this time, a pintle injector was considered for simplicity and lower cost on the Sea Dragon. In parallel with those projects, TRW continued development of other pintle engines, including by 1966 the URSA (Universal Rocket for Space Applications) series. These were bipropellant engines offered at fixed thrusts of 25, 100, or 200 lbf, (111, 445, or 890 N) with options for either ablative or radiatively cooled combustion chambers. These engines were capable of pulsing at 35 Hz, with pulse widths as small as .

The secondary armament consisted of a single pintle-mounted light M1918 Browning Automatic Rifle (BAR), meant as a form of anti-aircraft defence. To fire the BAR the gunner had to be exposed to enemy fire.

Pintle- and-gudgeon rudder of the Hanseatic league flagship Adler von Lübeck (1567–1581), the largest ship in the world at its time Oars mounted on the side of ships evolved into quarter steering oars, which were used from antiquity until the end of the Middle Ages in Europe. As the size of ships and the height of the freeboards increased, quarter steering oars became unwieldy and were replaced by the more sturdy rudders with pintle and gudgeon attachment. While Steering oars were found in Europe on a wide range of vessels since Roman times, including light war galleys in Mediterranean,the oldest known depiction of a pintle-and-gudgeon rudder can be found on church carvings of Zedelgem and Winchester dating to around 1180. A ship's rudder carved in oak, 15th century, Bere Ferrers church, Devon.

Because combustion tends to occur in the surface of a frustum, peak thermal stresses are localized on the combustion chamber wall rather than a more evenly distributed combustion across the chamber section and more even heating. This has to be contemplated when designing the cooling system, or it might cause burn-through. The pintle injector is known to have caused throat erosion problems in the early ablatively cooled Merlin engines due to uneven mixing causing hot streaks in the flow, however, as of 2019, it is not clear whether this is a problem that applies to all pintle-based engines, or if this was a design problem of the Merlin. Pintle injectors work very well with liquid propellants, and can be made to work with gelled propellants, but, for gas-liquid or gas-gas applications, conventional injectors remain superior in performance.

The alternator is of the integral rectifier and regulator type. The XR311 is provided with a heavy duty towing pintle as well as a trailer wiring harness receptacle. It is air-transportable and can be air-dropped.

Zaloga (1994), p. 11 Early vehicles had a pintle mount, just behind the front seats, that mounted a .50-caliber (12.7 mm) M2 Browning machine gun. The later M3A1 adopted a raised, armored pulpit mount for the .

Rhodesian MAP75s were usually armed with a FN MAG-58 7.62mm Light Machine Gun (LMG), sometimes installed on a locally produced one-man MG armoured turret to protect the gunner. Vehicles assigned to convoy escorting duties ('E-type') had a Browning M1919A4 7.62mm medium machine gun mounted on an open-topped, cylinder-shaped turret (dubbed 'the dustbin'). Twin Browning MG pintle mounts placed behind the driver’s compartment were often added on 'Seven fives' employed for 'externals'. The Zimbabwean vehicles after 1980 sported pintle-mounted Soviet-made 12.7mm and 14.5mm Heavy Machine Guns (HMG) instead.

Rhodesian MAP45s were usually armed with a FN MAG-58 7.62mm Light Machine Gun (LMG), sometimes installed on a locally produced one-man MG armoured turret to protect the gunner. Vehicles assigned to convoy escorting duties ('E-type') had a Browning M1919A4 7.62mm medium machine gun mounted on an open-topped, cylinder-shaped turret (dubbed 'the dustbin'). For 'externals' twin Browning MG pintle mounts were sometimes fitted, placed behind the driver's compartment. The Zimbabwean vehicles after 1980 sported single pintle-mounted Soviet-made 12.7mm and 14.5mm Heavy Machine Guns (HMG) instead.

The directing point (DP) was a term used in the U.S. Coast Artillery to identify a precisely surveyed point that was used as the point of reference for preparing the firing data used to aim the guns of a given Coast Artillery battery.See for example "FM 4-15: Coast Artillery Field Manual, Seacoast Artillery, Fire Control and Position Finding," U.S. Government Printing Office, Washington, 1943, p. 20 ff. Often the DP was taken as the pintle centerThe pintle center was the center of the gun pivot, mount point, or center of gravity of a gun.

The pintle is a highly stressed component during landing manoeuvres and is often made from exotic metal alloys. For World War II aircraft with sideways-retracting main gear units, carefully set-up "pintle angles" for such axes of rotation during retraction and extension allowed the maingear struts to be raked forward while fully extended for touchdown and better ground handling, while permitting retraction into rearwards-angled landing gear wells in their wings to usually clear the forward wing spar for stowing while in flight.Snyder, Chuck (August 2012). "How to Install Retractable Landing Gear".

Lug rigs are another common single sail type used in small dinghies, both standing and balanced (with some area forward of the mast), and usable with or without a boom. Traditional working dinghies have a lee board that can be hooked over the side. This does not split the cargo space. A sailing rudder is usually tied or clipped to a simple pair of pintles (hinge pins) on the transom with the bottom pintle being longer so that the rudder can be mounted one pintle at a time.

Ringfeders are used in nearly all aspects of world transport, the most common being LGVs (large goods vehicles) throughout Europe, and road trains in Australia. America uses a similar product known as a "pintle hook" or tow hitch.

30 cal M1919 Browning medium machine guns, all were mounted on a skate rail upon which the pintle mounts could be moved about. Due to its open top, the occupants were also able to employ their personal weapons.

The pintle injector is desirable for engines that have to be throttled or restarted repeatedly, but it does not deliver optimum efficiency for fuel and oxidizer mixing at any given throttle rate. Recirculation zones for a single injector engine.

Casement - the wood surrounding the window upon which the pintle is typically mounted. Hinges - Mate with the Pintles and are mounted on the shutter. Pintles - the "pins" on which hinges swing. The pintles are, by definition, mounted to the structure.

Most modern automotive engines are DI which have the benefits of greater efficiency and easier starting; however, IDI engines can still be found in the many ATV and small diesel applications. Indirect injected diesel engines use pintle-type fuel injectiors.

Armament on the TM-170 is optional and it is capable of being equipped with a pintle- or ring-mounted 7.62 mm machine gun, a turret armed with twin 7.62 mm MGs, or a turret armed with a 20 mm cannon.

Offset - the total dimension that the shutter will travel outwards when moved from the closed to the open position. The offset is typically the distance from the face of the casement to the outermost surface of the structure. The offset is developed in shutter hardware by selection a pintle made to "stand off" the casement a given distance - the shutter hinge has a sharp bend which moves the hinge barrel away from the face of the shutter at a distance to match the pintle standoff. When measuring offset, it is critical to allow for irregularities in construction.

Brick and stone openings are rarely plumb and never perfectly flat - look for the greatest dimension and allow about ½" cushion. If the offset is too small the shutters will not open fully - if the offset is too great, the shutter will function well and sit off of the wall a bit. I feel its good practice to set the shutters at least 1" off the face of the structure to allow air circulation across the back of the shutter. Standoff - The pintle standoff is the distance from the face of the casement to the mid- line of the pintle pin.

The body of the mill measures just under by in plan. The crowntree is square in section. It receives a diameter pintle projecting from the top of the main post. The side girts are by in section at the ends, thickening to at the crosstree.

The secondary arm was installed on the pintle of the secondary block. On the pintle of the primary block were installed the primary arm, the auxiliary arm, and the gun arm, as well as the complex gun arm center mechanism that was used to adjust the board for the location of the guns' directing point, to read the azimuth to the target, to adjust the firing data, and to tally the motion of the target between successive plotted positions. Plate XXVI (below, at right) shows a close-up of the gun arm center mechanism. The arc of the board was notched at one-degree intervals.

In the early 1980s, a series of design refinements were applied to the pintle injector obtaining exceptionally fast and repeatable pulses on command and linear throttling capability. By enabling shutoff of propellants at their injection point into the combustion chamber, the pintle injector provided excellent pulse response by eliminating injector "dribble volume" effects. Starting in 1981, a very compact, 8,200 lbf N2O4/MMH engine employing this feature was developed as a pitch and yaw thruster for the army's SENTRY missile program. This engine could throttle over a 19:1 thrust range and deliver repeatable "on" pulses as small as 8 milliseconds at any thrust level.

This may refer to hybrid jong, with middle rudder being like those on Chinese vessels (hanging axial rudder) or western axial rudder (pintle and gudgeon rudder).Liebner, Horst H. (2016). Beberapa Catatan Akan Sejarah Pembuatan Perahu Dan Pelayaran Nusantara. Jakarta: Indonesian Ministry of Education and Culture.

The system could be carried by a team of two soldiers and mounted either to an M122 tripod or a vehicle's pintle mount. Length overall is 104.1 cm, gun only is 68.6 cm long. Width (including ammunition case) is 44.4 cm. Sighting was usually by optical telescope.

In navigations locks, the upper pivot point for a miter gate is referred to as the gudgeon, and carries horizontal loads caused by a gate leaf hanging with no water load. The lower pivot, which carries the weight of the leaf, is referred to as the pintle.

Steering was provided by a stick controlling two air rudders aft of the propeller and propeller guard. Counting crew and passengers, the Aircat could carry payloads of up to . A .30 caliber (7.62 mm) M1919 machine gun was mounted on a pintle mount in the bow.

If the pintle is designed to move along its axis of rotation, the throat area can be varied. This would allow for effective throttling, whilst maintaining chamber pressure.Constant Chamber Pressure Throttling of an Expansion-Deflection Nozzle by Charles Schorr, Journal of Spacecraft and Rockets 1970 vol.7 no.

Steering involved upright steering levers to four hydraulic brakes on the sprockets and idlers. A spring-loaded pintle was fitted at the rear, and towing hooks were fitted in the front. It had a speed of about . The Kingdom of Romania purchased 100 RSO/01 tractors in 1943.

One or two pintle-mounted 7.62mm machine guns on the roof or a turret mounted 20 mm cannon. 13 vehicles intended for the Belgian Gendarmerie were equipped with an 81mm mortar. Shooting takes place through the open roof hatch. There is also the possibility of installing NBC protection system.

The mountings for the Army six pounders were called M1898 and M1898 (modified) "rampart mounts" or "parapet mounts", wheeled carriages with fittings that allowed them to be secured to pintle mounts.Lohrer, George L. Ordnance Supply Manual, U. S. Ordnance Dept., 1904, pp. 282-295 Another reference has somewhat different figures.

The rear-facing observer operates the radio and fires the pintle-mounted 7.62mm machine gun. Behind the commander, on the floor, was a drop-down escape hatch. The Canadian Lynx was withdrawn from service in 1993, and replaced by 203 Coyote eight- wheeled reconnaissance vehicles by the end of 1996.

Needham, Volume 4, Par634. Pottery boat from Eastern Han Dynasty showing rudder Paul Johnstone and Sean McGrail state that the Chinese invented the "median, vertical and axial" sternpost-mounted rudder, and that such a kind of rudder preceded the pintle-and-gudgeon rudder found in the West by roughly a millennium.

François, p. 32 The E. u. B. could fire from any suitable section of track after curved wedges were bolted to the track behind each wheel to absorb any residual recoil after the gun cradle recoiled backwards. It also had a pintle built into the underside of the front of the mount.

The casemate carriage has a lower profile than the barbette carriages. The 8-inch and 10-inch Rodman guns could be mounted on all three types of carriages. The 15-inch Rodman guns were mounted on both types of barbette carriage. The two 20-inch guns were mounted on front-pintle barbette carriages.

First Bull Run battlefield, the only weapon entirely designed by James adopted by the US Army. Two Model 1829 32-pounder seacoast guns, rifled by the James method (sometimes called 64-pdr James rifles). The one in the foreground is on a siege carriage. The one behind is on an iron, front pintle, barbette carriage.

François, p. 38 One obvious change made for land service was the placement of a small counterweight just forward of the trunnions to counteract the preponderance of weight towards the breech. This, although heavy, was simpler than adding equilibrators to perform the same function. Close up of the pintle under a "Peter Adalbert" E. u.

This simplifies the engine, reducing cost and improving reliability, while surrendering some performance. Grumman used the pintle-based Rocketdyne RS-18 for the Ascent stage of the Apollo Lunar Module. TRW used this same injector for the Descent Propulsion System on Apollo's Lunar Module. Notable modern uses are in the Merlin engines developed by SpaceX.

The body of the mill measures by in plan. The crowntree is by in section. It has a cast-iron plate bolted to its underside, with a pintle projecting downwards that fits into a cast-iron pot on the top of the main post, a reversal of the normal fitting. The side girts are by in section.

The M36 tank destroyer was equipped with a single .50 caliber (12.7 mm) Browning M2HB machine gun for antiaircraft or antipersonnel use, along with 1,000 rounds of ammunition. Because of the difficulty in firing the .50 caliber machine gun directly to the front, the pintle was often repositioned to the front of the turret, or a .

In addition to the wrecking body, all trucks had a front winch and a rear pintle hitch. Not intended to carry a load, the M1 could support while towing up to . The -A1 upgrade also had a rear winch, heavier bumpers, and a large front tow- bar, allowing the truck to recover and move light armored vehicles.

The vehicle usually has a one-man turret armed with a .50 BMG (12.7x99mm NATO) M2 Browning heavy machine gun. Some vehicles were fitted with a one-person gun turret armed with a 25mm cannon and a co-axial 7.62mm General-purpose machine gun. The turrets can be retrofitted with an automatic grenade launcher via pintle mount.

The 6.4-inch (100-pounder) Parrott Rifle was a potent siege gun capable of great accuracy and long range with heavy projectiles. For siege use it was mounted on a front pintle barbette carriage. It did, however, tend to burst. Of the three hundred 6.4-inch Parrott rifles in service with the U.S. Navy, 19 burst .

The TR-106 or low-cost pintle engine (LCPE) was a developmental rocket engine designed by TRW under the Space Launch Initiative to reduce the cost of launch services and space flight. Operating on LOX/LH2 the engine had a thrust of 2892 kN, or 650,000 pounds, making it one of the most powerful engines ever constructed.

The electrical system is 24V DC and two batteries with a capacity of 45 Amp/Hr are provided. The alternator is of the integral rectifier and regulator type. The Marine Multi-purpose Vehicle is proved with a heavy duty towing pintle as well as a trailer wiring harness receptacle. It is air-transportable and can be air-dropped.

Lewis and Clark's pirogues mounted blunderbuss to the bow with a pintle. In 626, when the Avars were besieging Constantinople, the Slavs crossed the Golden Horn in their pirogues and landed on the shore of the Lower Blachernae, and in spite of all defensive measures that were taken, looted churches.Dirimtekin, Feridun (1956) Fetihden Once Halic Surlari. Istanbul, Istanbul Enstitusu.

After the gun's pintle was bolted to the firing platform's pivot mount, the entire carriage was jacked up so that the trucks and their sections of rail could be removed. The carriage was then lowered so that the rear rollers rested on the outer track. Concrete versions were also used. It could have up to 360° of traverse.

Strap hinges continued to dominate in the marketplace, however, for hanging shutters. But here, too, changes were afoot. Drive pintles started to be replaced by similar pintles cut off and mounted on a piece of thin plate material and again fastened with the new screws. This is the precursor of the "plate pintle" that's still very much around.

Armament varies, the BPM-97 is available with pintle mounted or turret mounted 7.62 mm, 12.7 mm machine guns such as the Kord 12.7mm, 14.5 mm KPV heavy machine guns in a BTR-80 type turret, and a combination turret fitted with a sighting device with 30 mm cannon and 30 mm AGS-30 automatic grenade launchers.

Quad dog trailer A dog-trailer (also called a pup) is any trailer that is hooked to a converter dolly, with a single A-frame drawbar that fits into the Ringfeder or pintle hook on the rear of the trailer in front, giving the whole unit three to five articulation points and very little roll stiffness.

When the piece was to be hauled, the trail was raised above the limber, then lowered, with the pintle fitting into a hole in the trail. Unlike the situation with its predecessors, horses were harnessed to the 19th-century limber in pairs, with six to ten horses needed to haul a siege gun or howitzer.Gibbon, p. 176.

BMC Kirpi has monocoque V-shaped body. Recovery and/or towing points are fitted front and rear, a NATO standard pintle being fitted at the rear. A front-mounted hydraulically operated self-recovery winch is standard. V-shape monocoque body with composed add-on armor offers great resistant against mine and ballistic attacks in terms of NATO Stanag 4569.

Although the W85 was not accepted into Chinese service, years later a variant was adopted called the QJC-88. The QJC-88 was introduced as a pintle mounted machine gun for tanks and armored vehicles. It weighs the same, is solenoid fired, and is mounted on a special cradle allowing for elevation angles of -5 to +65°.

In 1972 the Apollo Descent Propulsion System ended production, but starting in 1974, and continuing through 1988, the TR-201, a simplified, low cost derivative of it, featuring ablative cooling and fixed thrust, was used in the second stage of the Delta 2914 and 3914 launch vehicles. In October 1972, the pintle injector design was patented and made public.

A few were fitted with additional equipment for use as field ambulances, telephone line-laying vehicles or equipped with armour and a .303 in Vickers medium machine gun or .303 Bren light machine gun utilising the built-in pintle mount forward of the windscreen, but the majority served as cargo/personnel carriers or were fitted with radios.

A one-man turret similar to the Mine Protected Combat Vehicle (MPCV), which accommodated either 12.7mm or 14.5mm Heavy Machine-Guns (HMGs) could be fitted on the top roof though the vehicle also served without it and with other armament such as a pintle-mounted 20mm autocannon or a FN MAG-58 7.62×51mm NATO light machine-gun.

First Bull Run battlefield, the only weapon entirely designed by James adopted by the US Army. Two Model 1829 32-pounder (14.5 kg) seacoast guns, rifled by the James method (sometimes called 64-pdr (29 kg) James rifles). The one in the foreground is on a siege carriage. The one behind is on an iron, front pintle, barbette carriage.

Changing the wings required only three hours work per aircraft. The Hurricane was furnished with a laterally-retracting undercarriage, the main undercarriage units being able to slide into recesses within the wing. Hinged telescopic Vickers-built legs are attached to the bottom boom of the wing's forward spar, but with a complex "pintle" angle setup within the wing at the top of the strut, to allow the strut to be perpendicular to the thrust line when extended, and angling rearwards as it retracted to clear the forward spar. A hydraulic jack served to actuate the undercarriage, with the carefully set "pintle" angle of the strut's upper ends assisting in the folding and pivoting the legs as to reposition the wheel unit rearwards as well as inwards in order to clear the front spar when retracted.

FSO pintle injectors were used on a variety of programs, the McDonnell Douglas Advanced Crew Escape Seat – Experimental (ACES-X) program and its successor, the Gel Escape System Propulsion (GESP) program. Another major design adaptation in this time period was the use of pintle injectors with cryogenic liquid hydrogen fuel. Beginning in 1991, TRW joined with McDonnell Douglas and NASA Lewis (now Glenn) Research Center to demonstrate that TRW's pintle engine could use direct injection of liquid hydrogen to simplify the design of high-performance booster engines. Attempts to use direct injection of cryogenic hydrogen in other types of injectors had until then consistently resulted in the onset of combustion instabilities. In late 1991 and early 1992, a 16,000 lbf (71,172 N) LOX/LH2 test engine was successfully operated with direct injection of liquid hydrogen and liquid oxygen propellants. A total of 67 firings were conducted, and the engine demonstrated excellent performance and total absence of combustion instabilities. Subsequently, this same test engine was adapted for and was successfully tested with LOX/LH2 at 40,000 lbf (177,929 N) and with LOX/RP-1 at 13,000 and 40,000 lbf. (57,827 and 177,929 N). At the same time, TR-306 liquid apogee engines were used on the Anik E-1/E-2 and Intelsat K spacecraft.

While the RBY Mk 1 featured no integral armament, provisions were made for up to five machine guns by placing pintle mounts at various points around the vehicle. Passenger seating was provided with two back-to-back rows of three outward-facing seats. This allowed the passengers to maintain a full 360 degree field of view and operate any mounted machine guns.

The selected configuration consisted of a high density, erosion-resistant silica cloth/phenolic material surrounded by a lightweight needle-felted silica mat/phenolic insulation. The installed pintle injector, unique to TRW-designed liquid-propulsion systems, provides improved reliability and less costly method of fuel–oxidizer impingement in the thrust chamber than conventional coaxial distributed- element injectors typically used on liquid bipropellant rocket engines.

Colt produced a derivative of the M2 aircraft machine gun, the Colt MG40. It shipped in a variety of calibers, including the basic .30-06 Springfield and popular 7mm Spanish Mauser, and was available in left- or right-hand feed. The MG40-2 Light Aircraft Machine Gun could be used in flexible- (pintle- mounted), fixed- (wing-mounted), or synchronized- (through the propeller) models.

In its "heavy" configuration (which includes the tripod) it is carried by a crew of three, and can make effective use of the 15-round drum and fully automatic fire. Like heavier AGLs it can be pintle-mounted on vehicles, but troop feedback indicates mounted magazine reloading is both difficult, and frequent because of the low ammunition capacity.QLZ87 Weapon Systems.

This assumes that the face of the shutter will lie on the same plane as the casement with the shutter in the closed position. This seldom happens in contemporary construction - incorrect hardware is installed - the homeowner hears "well, you'll never close them anyway". Hinge and pintle standoffs can be custom made to each customer's situation. This eases installation and insures proper shutter function.

The chassis would pivot to train the gun left or right. The barbette carriages were designed to fire over a parapet and could be used in either permanent or temporary fortifications. The front pintle carriage pivoted at the front of the chassis. This made the gun mount more compact and allowed the gun and detachment to be better protected by embrasures and traverses.

BMC Amazon has monocoque V-shaped body. Recovery and/or towing points are fitted front and rear, a NATO standard pintle being fitted at the rear. A front-mounted hydraulically operated self-recovery winch is standard. V-shape monocoque body with composed add-on armor offers a good amount of resistant against mine and ballistic attacks in terms of NATO Stanag 4569.

In order to keep the device from blowing itself apart during high energy tests, the outer tube was retracted, constituting then a primitive pintle injector. Peter Staudhammer, under the supervision of Program Manager Elverum, had a technician cut multiple slots across the end of an available inner tube and subsequent tests of this new configuration showed a substantial improvement in mixing efficiency.

Lynx. A pintle mount is a fixed mount that allows the gun to be freely traversed and/or elevated while keeping the gun in one fixed position: typically the mounting is either a rod on the underside of the gun (a pintle rod) that mates with a socket, or an intermediary gun cradle that mounts to the sides of the weapon's barrel or receiver. Due to the stability offered by the mount, the gun typically does not use a shoulder stock, with many modern examples using spade grips. It is most commonly found on armoured vehicles, technicals, side gun stations on WW2 and earlier bomber aircraft, and the door guns of transport helicopters. Early single-shot examples referred to as swivel guns were commonly mounted on the deck rails of naval vessels in the age of sail to deter boarders at close range.

Both flow paths are active. If fuel is chosen for the inner flow (which is the case in most pintle-based engines), the injector can be tuned so that any excess fuel which is not reacted immediately as it passes through the oxidizer stream is projected onto the combustion chamber walls and cools them through evaporation, thus providing fuel film cooling to the combustion chamber walls, without incurring the mass penalty of a dedicated coolant subsystem. While pintle injectors have been developed for applications in rocket propulsion, due to their relative simplicity, they could easily be adapted for industrial fluid handling processes requiring high flowrate and thorough mixing. A given injector's performance can be easily optimized by varying the geometries of the outer propellant's annular gap and the central propellant slots (and/or continuous gap, if used).

By 1960, Elverum, Grant, and Staudhammer had moved to the newly-formed Space Technology Laboratories, Inc. (Later TRW, Inc.) to pursue development of monopropellant and bipropellant rocket engines. By 1961, the pintle injector was developed into a design usable in rocket engines, and subsequently, the pintle injector design was matured and developed by a number of TRW employees, adding such features as throttling, rapid pulsing capability, and face shutoff. Throttling was tested in the 1961 MIRA 500, at 25 to 500 lbf (111 to 2,224 N) and its 1962 successor, the MIRA 5000, at 250 to 5,000 lbf (1,112 to 22,241 N). In 1963, TRW introduced the MIRA 150A as a backup for the Thiokol TD-339 vernier thruster to be used in the Surveyor probes, and started development of the Apollo Lunar Excursion Module's Descent Propulsion System.

The pintle-mounted machine gun is retained. The Dragoon ALSV (Armored Logistics Support Vehicle) is a Dragoon APC fitted out as an armored truck of sorts. The load area in this vehicle is open-topped, and there is a materiel-handling crane with a capacity of 1 ton. It can carry standard NATO pallets and containers, as well as several makes of civilian ones.

The TR-106 or Low Cost Pintle Engine (LCPE) was a developmental LH2/LOX rocket engine designed by TRW under the Space Launch Initiative. It had a planned sea-level thrust of 650,000 lbf. It was tested at NASA John C. Stennis Space Center throughout 2000. The Stennis test stand results demonstrated that the engine was stable over a wide variety of thrust levels and propellant ratios.

The descent propulsion system (DPS - pronounced 'dips') or lunar module descent engine (LMDE) is a variable-throttle hypergolic rocket engine invented by Gerard W. Elverum Jr. and developed by Space Technology Laboratories (TRW) for use in the Apollo Lunar Module descent stage. It used Aerozine 50 fuel and dinitrogen tetroxide () oxidizer. This engine used a pintle injector, a design also used later in the SpaceX Merlin engine.

Whaleboats generally used a dismountable mast for distance work or for towing a carcasse, but depended on oars for close-in work. Boats used strictly for whaling often used only a long steering oar, while those used as ship’s boats often had dismountable pintle-and-gudgeon rudders as well. A main sail, and occasionally a jib were used. After 1850 most were fitted with a centreboard.

Although the turret with all of the main armament was removed, the two bow mounted machine guns have been retained. However, the original PKT tank machine guns have been replaced by PKB general purpose machine guns. The vehicle can also be fitted with pintle-mounted automatic grenade launchers (AGS-17, AGS-30 or AGS-57) and/or machine guns (PKM, 6P41, "Utyos" or "Kord").

The company also enters the "body" business instead of just building the "chassis." Separate design and production divisions are created at Utility and increased product innovation is the result. Utility introduces the use of the elliptical spring running gear, plus an axle suspension system that eliminates weight transfer during braking. And, the company invents and patents the first shockless air-operated pintle hook for doubles operation.

The APC variant has no permanent armament but it has pintle mounts for three 7.62 mm SGMB medium machine guns, one at the front of the troop compartment and the other two at the sides. The vehicle also has two firing ports on both sides of the hull which allow up to four soldiers to use their weapons while being protected by the APC's armour.

Wanting a fuel tanker larger than the CCKW, the Army ordered 25 from White. The body had 4 self-sealing tank compartments for a total of . A bow and canvas top was fitted, so the truck could be disguised as a common cargo truck. Early trucks had a hard cab and a front-mounted pintle hitch, later trucks had an open cab and a front winch.

Co- axially mounted with the machine gun both weapons were pintle-mounted, and fitted with an elevation and traverse mechanism and floor-mounted firing mechanisms. The turret was rotated by the traversing weapons rather than the weapons being fixed to a traversing turret. There was thus no bearing-ring and no turret basket, only a fighting compartment largely obstructed by the breaches of the weapons.

259–262 Driggs-Schroeder designed 6-pounders designated Marks II and III for the Army; they possibly corresponded to the Navy Marks 6 and 8.Lohrer, pp. 282–295 Some of these weapons were deployed at coastal artillery forts for land defense. These included experimental quantities on "parapet mounts", wheeled carriages with fittings that allowed them to be secured to pintle mounts set in concrete.

The Bren was also used on many vehicles, including on Universal Carriers, to which it gave the alternative name "Bren Gun Carrier", and on tanks and armoured cars. It could not be used as a co-axial weapon on tanks, as the magazine restricted its depression and was awkward to handle in confined spaces, and it was therefore used on a pintle mount only. (The belt fed Vickers or Besa, the latter being another Czechoslovak machine gun design adopted by the British, were instead used as co-axial weapons.) An unfortunate problem occurred when the Bren was fired from the Dingo Scout Car; the hot cartridge cases tended to be ejected down the neck of the driver, whose position was next to the pintle. A canvas bag was designed to catch the cartridges and overcome the problem, but it seems to have been rarely issued.

The ring mount on the left side of the turret for the .50 caliber Browning M2HB antiaircraft machine gun was changed to a pintle mount at the rear. It was decided that production vehicles would use the chassis of the M10A1 tank destroyer, as significant numbers of M10A1s were available, and it was determined that the M10A1 had superior automotive characteristics. After testing, an initial order for 300 vehicles was issued.

The M60B was a short-lived variant designed to be fired from helicopters, with limited deployment made in the 1960s and 1970s. It was not mounted, just held, and was soon replaced by the pintle-mounted M60D. The 'B' model differed most noticeably in that it had no bipod and featured a different rear stock than the regular model. It still had a pistol grip (as opposed to spade grips).

An M60D machine gun on the M23 Armament Subsystem. The M60D is a mounted variant of the standard M60. It can be mounted on boats, vehicles and as a pintle-mounted door gun in helicopters. When used in aircraft, it differs from the M60C in that it is not controlled by the pilot—rather, it is mounted in a door and operated by a member of the crew.

Mk.1 helicopter, and launched a Westland Lynx HAS Mk 2. The Lynx launched a torpedo, and strafed the submarine with its pintle-mounted general purpose machine gun; the Wessex also fired on Santa Fe with its GPMG. The Wasp from as well as two other Wasps launched from fired AS-12 ASM antiship missiles at the submarine, scoring hits. Santa Fe was damaged badly enough to prevent her from diving.

She was fitted with replenishment-at-sea equipment, freshwater generators, satellite navigation and satellite communications systems. Additional crew and troop accommodation was also installed. The vessel was also fitted with pintle-mounted Bren light machine guns as a rudimentary defence against low-level air attack. The Europic Ferry loaded at Portsmouth and departed for the South Atlantic on 25 April, stopping briefly at Portland Harbour on her way past.

An armored cupola containing eight vision blocks covers the driver's compartment. The vehicle hull is welded and bolted aluminum with a two speed winch capable of 25,000 pound (110 kN) line pull. Towing pintle and airbrake connections are provided. It is equipped with a suspension system which allows the front of the vehicle to be raised, lowered, or tilted to permit dozing, excavating, rough grading and ditching functions.

The gun was moved over the firing platform and then lowered into position after the central section of rail was removed. After the gun's pintle was bolted to the firing platform's pivot mount, the entire carriage was jacked up so that the trucks and their sections of rail could be removed. The carriage was then lowered so that the rear rollers rested on the outer track. Concrete versions were also used.

Merlin is a family of rocket engines developed by SpaceX for use on their launch vehicles. Merlin engines use LOX and RP-1 as propellants in a gas-generator power cycle. The Merlin engine was originally designed for sea recovery and reuse. The injector at the heart of Merlin is of the pintle type that was first used in the Apollo Program for the lunar module landing engine.

Changes in construction are noted in the same period. Instead of building the structure around the heavy wooden frame of the window, you would see structures built with openings into which pre-fabricated windows were installed. The earliest examples I've seen date from around 1810 and utilized a very nice variation on the strap hinge. Instead of mounting the pintle to the surface of the structure a new form was designed.

That leaves the shutter with a little breathing room and clears the corner of the casing - it's a nice angle between the shutter and house. The question of security – lifting the shutter and hinges from their pintles is resolved by installing the top pintle in the inverted position. Installation problem: However it happens, this is the toughie. There is an offset and the shutter does not sit flush with the casing.

In July, 2017, Canadian Special Operations Forces Command exercised the option to procure an additional 10 ULCV, bringing the total number of ULCV under this acquisition to 62. The vehicle can be configured in up to 48 different weapon configurations using the weapons ring and multiple pintle mounts. The vehicle is powered by a light weight, commercial off-the-shelf turbo diesel / JP8 engine located at the front section.

The basic cargo model was a prime mover used to tow the 155 mm howitzer M1 and transport the gun crew, equipment, and ammunition. They had a pintle hitch at the rear to tow up to off-road and on road. With a short wheelbase and rear overhang, the body could only be feet long. It had sideboards with fold down troop seats and bows for an overhead tarpaulin.

The bipod also offers a 15° range of rotation to either side. With the bipod fully extended, the bore axis is elevated to a height of . The Minimi can also be fired from the Belgian FN360° tripod or the American M122 mount using an M60 pintle. The vehicle-mounted Minimi is fitted with an electrically powered trigger that enables it to be fired remotely from within an armored fighting vehicle.

It is primarily intended for reconnaissance activities, particularly behind the enemy lines. It was converted to be used in a variety of different roles such as an artillery observation post, a mobile command/observation post and NBC reconnaissance. The Hungarian FÚG version can be fitted with a pintle-mounted RPD LMG, but on the OT-65 the main weapon was a 7.62 UK light machine gun (vz. 59) with electromagnetic release.

A ladder frame had two live beam axles on leaf springs with a wheelbase. There was a winch behind the front bumper and a pintle hitch at the rear. A civilian type closed cab was used, right behind the cab was an open cargo box used to carry engineer tools, outboard motors, and other equipment. Early semi-tractors and all vans used 9.75x20 tires, later semi-tractors had 12.00x20 tires.

Since the Chinese junk lacked a sternpost, the rudder was attached to the back of the ship by use of either socket-and-jaw or block and tackle (which differed from the later European pintle and gudgeon design of the 12th century).Adshead (2000), 156; Mott (1991), 2–3, 92, 84, 95f. As written by a 3rd-century author, junks had for-and-aft rigs and lug sails.Temple (1986), 187.

12.7 mm DShK 1938 was used an anti-aircraft weapon it was mounted on pintle and tripod mounts, and on a triple mount on the GAZ-AA truck. Late in the war, it was mounted on the cupolas of IS-2 tanks and ISU-152 self-propelled guns. As an infantry heavy support weapon it used a two-wheeled trolley which unfolded into a tripod for anti-aircraft use.

The XM213/M213 was a modernization and adaptation of existing .50 caliber AN/M2s in inventory for use as a pintle- mounted door gun on helicopters using the M59 armament subsystem. The GAU-15/A, formerly identified as the XM218, is a lightweight member of the M2/M3 family. The GAU-16/A was an improved GAU-15/A with modified grip and sight assemblies for similar applications.

The M60C was adopted for use on fixed mounts on aircraft. It was characterized by the use of an electric solenoid to operate the trigger and a hydraulic system to charge the weapon. The M60D differed from the base model by employing spade grips, a different sighting system, and lacking a forearm. It was typically employed as a door gun on helicopters or as a pintle-mounted weapon as on the Type 88 K1 tank.

By 1974, all Israeli Centurions were upgraded to Sho't Kal (Mk 13 armour) and had a pintle-mounted .50 cal HMG. Sub-variants indicate upgrades received by Sho't Kal tanks during their operational life, including a new turret rotating mechanism, a new gun stabiliser, a new fire-control system and preparations for the installation of the Blazer ERA. ;;Nagmashot / Nagmachon / Nakpadon :Israeli heavy armoured personnel carriers based on the Centurion tank's chassis.

The ability to locate receiver equipment at the horn apex, thus eliminating the noise contribution of a connecting line, is an important feature of the antenna. A radiometer for measuring the intensity of radiant energy is located in the cab. The triangular base frame of the antenna is made from structural steel. It rotates on wheels about a center pintle ball bearing on a turntable track 30 feet (10 m) in diameter.

The turret was highly similar to the one on OT-62B, but with significantly lower silhouette. Therefore, the major drawback of D-442 FUG was the lack of permanent armament, and lack of firing ports was later considered a major design flaw. To operate the pintle-mounted 7.62 mm light machine gun in the front, the soldier had to expose himself to enemy fire. The vehicle shares characteristics with both BRDM-1 and BRDM-2.

Modelled after Panhard's AML HE-60-7, the Eland-60 was the first Eland variant to enter service. It is armed with twin 7.62mm machine guns on the left and a single 60mm mortar on the right. Unlike its French predecessor, only one machine gun is mounted coaxially in the turret. A second was typically carried on a pintle for anti-aircraft use. The mortar has an elevation of +75° and a depression of -11°.

The . bipod-mounted version was marketed as a light machine gun for use by assault troops. It was the only version with a buttstock. The . tripod-mounted version was considered a medium machine gun. The vehicle mounted version was a pintle- mounted machine gun for use by soldiers in land vehicles. The fixed mount version was fired by a solenoid allowing for remote operation so it could be mounted in a helicopter or other aircraft.

The M9 used the same chassis and mechanical components as the M5. It was laid out to provide similar stowage, access to the radios from the inside, rear doors, and a pedestal machine gun mount as with the M2.Berndt (1993) p. 147. The M9A1 variant of the M9 matched the improvements made to the M2, M3, and M5, changing to ring mount machine gun mount and three pintle machine gun mounts.

Air brake connections at the rear were used for trailer brakes. The M815, M818, and M819 had separate controls to apply the trailer brakes separately from the service brakes. All M809 models had a rear pintle hitch and could tow trailers except the M816, which could tow The M818 and M819 could tow semi trailers on their fifth wheel. Many M809 series were equipped with a front-mounted capacity winch, intended for self-recovery.

TR-106 on astronautix Development of the engine was temporarily discontinued with the cancellation of the Space Launch Initiative. Since 2000, TRW has been acquired by Northrop Grumman and development of the TR-107 RP-1/LOX rocket engine began in 2001 for potential use on next-generation launch and space transportation vehicles is continuing under contract to NASA.Northrop Grumman booster vehicle engines Technology lessons from the Low Cost Pintle Engine project assisted subcontractor development of engines by SpaceX.

The spadix produces heat and probably scent as the flowers mature, and this may attract the rodents. Arum maculatum is also known as cuckoo pint or cuckoo-pint in the British Isles and is named thus in Nicholas Culpepers' famous 17th-century herbal. This is a name it shares with Arum italicum (Italian lords-and-ladies) - the other native British Arum. "Pint" is a shortening of the word "pintle", meaning penis, derived from the shape of the spadix.

Also offered are a suite of accessories such as a snowplow, pintle hitch, front brush guard, security light, hot dog cooker and others. The Tiger Star model is an upgraded and more robust off-road utility truck than most off-road vehicles in its class. The advanced Star class trucks feature robust electric drive, with a 48 volt, 5 kW motor mated with a five-speed transmission. All Tiger Trucks are California Air Resources Board certified.

"PN inspects 2 attack choppers." Manila Standard, 23 May 2015. Optional mission equipment for the AW109 has included dual controls, a rotor brake, windshield wipers, a fixed cargo hook, snow skis, external loudspeakers, wire-strike protection system, engine particle separator, engine compartment fire extinguishers, datalink, and rappelling fittings. A range of armaments can be installed upon the AW109, including pintle-mounted machine guns, machine gun pods, 20mm cannons, rocket pods, anti-tank missiles and air-to-air missiles.

A marine performs maintenance on a mounted M240 pintle-mounted machine gun on an LAV The manufacturer's name for the weapon is the MAG 58. The M240 adheres to FN MAG-58 specifications, allowing parts to be interchanged with other standard MAG-58s. This has significant advantages in training, logistics support, tactical versatility, and joint operations. For example, a US unit with attached British troops could supply replacement parts for their GPMG L7s, and vice versa.

303 machine gun.Martin, p 36-42 The first major overseas deployment of Irish troops was to the Congo in 1960 as part of the UN force ONUC. In 1961 an Armoured Car Group with eight Ford Mk VI armoured cars was flown to the Congo. Three more Ford Mk VIs were sent out later that year to the Congo, 2 of which had their turrets removed and a pintle-mounted Bren light machine gun fitted in its place.

A swing mount is a fixed mount that allows a far greater and more flexible arc of fire than the simple pintle mount system. Utilising a system of one or two articulated arms the gunner can swing the weapon through a wide arc even though the gunner's position is fixed relative to the mount. These systems vary in complexity from a simple arm, to a double arm with the ability to lock the weapon in any firing position.

It was originally adopted for vehicle mounting in the late 1970s, but its higher reliability resulted in the infantry adopting it for use over the M60 machine gun, despite it being several pounds heavier. They both have quick-detachable barrels, bipods in their light infantry model, tripod and pintle mount options for other models, and similar weight and size. The M60 was typically referred to either as a light machine gun or a general-purpose machine gun.

The SpaceX Merlin is a family of rocket engines developed by SpaceX for use on its Falcon 1, Falcon 9 and Falcon Heavy launch vehicles. Merlin engines use RP-1 and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for sea recovery and reuse. The injector at the heart of Merlin is of the pintle type that was first used in the Apollo Lunar Module landing engine (LMDE).

This style is traditional to suburbs of Philadelphia, Pennsylvania, including Chester, Bucks, and Montgomery Counties where it is a common and fairly straightforward situation. The amount of the required offset is divided evenly between the hinge and the pintle. The biggest problem here is determining the offset correctly. The home is usually stone or brick and the walls are never true and plumb - the distance from the casing to several points on the masonry can be scary.

The basic principles of the Fastrac design (namely, a pintle injector and ablatively cooled chamber) lived on in SpaceX's Merlin 1A engine, which used a turbopump from the same subcontractor. The Merlin-1A was somewhat larger with a thrust of versus for Fastrac. The same basic design was capable of much higher thrust levels after upgrading the turbopump. Variants of the Merlin-1D achieve of thrust as of May, 2018, though the combustion chamber is now regeneratively cooled.

The Wolfhound had a crew of four and was armed with a 37 mm gun in a rotating open-topped turret, with an ammunition load of 93 rounds. Its secondary armament consisted of two machine guns; one mounted co-axially with the main weapon, the other on an AA pintle mounting. It was powered by a Cadillac, eight-cylinder, water-cooled engine. Each side featured three large tires on symmetrically placed axles, with distinctive curved mudguards.

This somewhat beard-like sternward extension of the keel is the basic skeg. Subsequently, the lowest pintle was commonly mounted below the rudder on a metal extension of the keel. This helped further stabilize and protect the rudder and the name skeg was transferred to it. It used to be relatively small until screw propellers were introduced, when it had to reach below the screw and became a proportionately larger feature protecting both screw and rudder from damage.

2nd Battalion 1st Marines fire an 81mm mortar from an M733 near Marble Mountains, 1970 The M733 was an armored variant of the M116 with steel armour plates added to provide ballistic protection capable of stopping .30-caliber ball ammunition. The purpose of the vehicle was to provide small arms protection for infantry security elements accompanying marginal terrain vehicles. The primary armament was one M60 machine gun, but two other pintle mounts were provided for additional M60s.

The turret was regarded as unsatisfactory by soldiers, as it was cramped and it proved difficult to keep the guns aimed when the vehicle was moving. The turret was also very slow to rotate, which led to delays in engaging targets. To free up space, the right-hand side L3A3 machine gun was removed from all the T50 turrets in South Vietnam by early 1970; these guns were instead fitted to the roof of the turret using a pintle mount.

Third, the processor was not allowed to start until the internal voltage was stabilized above 10 volts. The EEC-II controlled air-fuel ratio via the Ford proprietary model 7200 Variable Venturi (VV) Carburetor. This was the last carburetor designed and built by Ford US. It was considered to be the pinnacle of carburetor design. Air-fuel ratio was controlled by a stepper motor that operated a rack which moved a pintle that opened and closed the float bowl vent.

A Westland Lysander IIIA preserved at the Steven F. Udvar-Hazy Center ;Lysander Mk.I :Powered by one 890 hp (664 kW) Bristol Mercury XII radial piston engine. Two forward-firing 0.303 in (7.7 mm) Browning machine guns in wheel fairings and one pintle-mounted 0.303 in (7.7 mm) Lewis or Vickers K machine gun in rear cockpit. Optional spat-mounted stub wings carried 500 lb (227 kg) of bombs. Four 20 lb (9 kg) bombs could be carried under rear fuselage.

The fuel system is a very simple design. A mechanical or electric fuel lift pump feeds a Stanadyne Rotary Distributor Injection pump at low pressure. The distributor injection pump controls both metering, via an internal centrifugal governor, and high pressure fuel delivery to the fuel injectors via internal precision hydraulic pumps. Near the top of the compression stroke fuel is atomized at high pressure into a hemispherical Inconel prechamber in the cylinder heads using Bosch pintle and seat mechanical fuel injectors.

She has no dedicated armament though she can be fitted with pintle-mounted L7 7.62 mm GPMG machine guns. Biter is part of the First Patrol Boat Squadron (1PBS) based at HMNB Portsmouth. During overhaul, two Cat C18 ACERT propulsion engines were installed by Finning Power Systems. The two diesel engines, each rated at 873 bhp at 2200 rpm, form part of the propulsion package along with ZF 2000 RV marine reverse reduction gearboxes and ZF 9000 Series ClearCommand controls.

B. could fire from any suitable section of track after curved wedges were bolted to the track behind each wheel to absorb any residual recoil after the gun cradle recoiled backwards. It also had a pintle built into the underside of the front of the mount. Two large rollers were fitted to the underside of the mount at the rear. Seven cars could carry a portable metal firing platform (Bettungslafette) that had a central pivot mount and an outer rail.

Propellants are fed via a single shaft, dual impeller turbo-pump. Kestrel is a LOX/RP-1 pressure-fed rocket engine and was used as the Falcon 1 rocket's second stage main engine. It is built around the same pintle architecture as SpaceX's Merlin engine but does not have a turbo- pump, and is fed only by tank pressure. Its nozzle is ablatively cooled in the chamber and throat, is also radiatively cooled, and is fabricated from a high strength niobium alloy.

Because tank crews have limited visibility from inside the tank, infantry can get close to a tank given enough concealment and if the hatches are closed. If tank crewmen unbutton for better visibility they become vulnerable to small arms fire, grenades and molotov cocktails. An infantryman cannot be targeted by a tank's main gun when close, as it cannot depress sufficiently. Close defense weapons such as pistol ports, hull-, coaxial- and pintle-mounted machine guns gave them some protection however.

Like all of the previous T-80 models, the T-80U has full length rubber side skirts protecting the sides with those above the first three road wheels being armoured and are provided with lifting handles. It can fire the 9M119 Refleks (AT-11 Sniper) guided missile and the long-rod penetrator (HVAPFSDS) 3BM46. The remotely-controlled commander's machine gun was replaced by a more flexible pintle-mounted one. A special camouflage paint distorts the tank's appearance in the visible and IR wavebands.

A release lever beside the thumbscrew allowed the entire assembly to be lifted off the mounts. Above the mounting platform was the stabilization gyro. This was connected to a pie-wedge-shaped metal plate, causing the plate to rotate around a mounting point at the top of the wedge. The rear part of the reflector sight was mounted at this point and the opposite, forward, end was supported by a rotating pintle inserted into a gudgeon mounted to the frame.

BRDM-1 with 7.62mm SGMB machine gun The BRDM-1 (also known as the BTR-40P) first appeared in 1959, and was in production until 1966. Total production was around 10,000 vehicles; less than 600 remain in the reserves of a number of countries. It was armed with a pintle-mounted heavy machine gun. The initial version of the vehicle, the Model 1957, had an open roof, but the standard production model, the Model 1958, had a roof with twin hatches.

The M60E2 was electrically fired, but had a manual trigger as a backup, as well as a metal loop at the back for charging. The gas tube below the barrel was extended to the full length of the weapon to vent the gas outside the vehicle. This version achieved a mean time between failures of 1,669 during testing in the 1970s. The M60E2 is used on the South Korea's K1 Type 88 tank as a co-axial weapon, along with an M60D on a pintle mount.

The TR-201 or TR201 is a hypergolic pressure-fed rocket engine used to propel the upper stage of the Delta rocket, referred to as Delta-P, from 1972 to 1988. The rocket engine uses Aerozine 50 as fuel, and as oxidizer. It was developed in early 1970s by TRW as a derivative of the lunar module descent engine (LMDE). This engine used a pintle injector first invented by Gerard W. Elverum Jr. and developed by TRW in late 1950s and received US Patent in 1972.

Only three 10-inch (300-pounder) Parrotts saw service during the war; all placed on Morris Island during the campaign against Charleston harbor. It was mounted on a center pintle, barbette carriage. It was essentially an enlarged 8-inch Parrott rifle, although it was believed to be somewhat more accurate than the 8-inch rifle . One 10-inch Parrott rifle on Morris Island was disabled soon after it first opened fire by the premature detonation of a shell, which blew about 18 inches off its muzzle.

Tom Mueller was a lead engineer for development of the LCPE,Mueller, Tom; Dressler, Gordon. TRW 40 klbf LOX/RP-1 low cost pintle engine test results. 35th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, Huntsville, Alabama, July 24, 2000 a 650,000 lbf thrust LOX/LH2 engine. In the summer of 2000, this LCPE was successfully hot fire tested at 100 percent of its rated thrust as well as at a 65 percent throttle condition at NASA's John C. Stennis Space Center in Mississippi.

Towing may be as simple as a tractor pulling a tree stump. The most familiar form is the transport of disabled or otherwise indisposed vehicles by a tow truck or "wrecker." Other familiar forms are the tractor-trailer combination, and cargo or leisure vehicles coupled via ball or pintle and gudgeon trailer hitches to smaller trucks and cars. In the opposite extreme are extremely heavy duty tank recovery vehicles, and enormous ballast tractors involved in heavy hauling towing loads stretching into the millions of pounds.

An open-topped turret was fitted as standard to the BA-64 series, with a 7.62mm light machine gun mounted on a pintle to the right. The machine gun mount was designed for maximum elevation so it could engage low-flying aircraft or infantry in the upper floors of a building during urban combat. A very small number of BA-64s were fitted with a 12.7mm heavy machine gun in a larger, open-topped turret. This model included splash guards and armoured fillets on the hull roofline.

It also had a pintle built into the underside of the front of the mount. Two large rollers were fitted to the underside of the mount at the rear. Seven cars could carry a portable metal firing platform (Bettungslafette) that had a central pivot mount and an outer rail. It was assembled with the aid of a derrick or crane, which took between three and five days, and railroad tracks were laid slightly past the firing platform to accommodate the front bogies of the gun.

Kestrel was built around the same pintle architecture as the SpaceX Merlin engine but does not have a turbopump and is fed only by tank pressure. Kestrel is ablatively cooled in the chamber and throat and radiatively cooled in the nozzle, which is fabricated from a high strength niobium alloy. As a metal, niobium is highly resistant to cracking compared to carbon-carbon. According to SpaceX, an impact from orbital debris or during stage separation might dent the metal but have no meaningful effect on engine performance.

The cradle support also has a bolt for locking the barrel in centre for traverse before towing the gun. There are small spades at the end of each trail leg, and fittings for large spades that are carried on the side of each trail leg. The large spades are used on soft ground and are fitted to the trail ends via have a pintle in the same way as the similar spades on M-46. These spades are the main difference from the D-20 carriage.

M19 1-ton snow trailer Saginaw Products made the M19 ski-wheel trailers. Two production batches are known, one in 1944 and one in 1950. The M19 trailer had a net weight of 640 lbs, and a payload of 2,000 lbs. It had a wooden body on a steel hollow-section frame, with hood, hoops, side and end panels all easily detachable, and it was normally equipped with a heater and two stretchers, plus a rear pintle hitch so that trailers could be doubled up.

Initially however not all helicopters were armed or outfitted with a dedicated MG for door armament. For example the very first U.S. Army helicopter units, flying CH-21 helicopters, that began flying combat missions in Vietnam in 1962 didn't. Therefore door gunners on Vietnam photographs are sometimes seen using an M1 Carbine, an M14 rifle, or an M16 rifle, as their only weapon. Initially, the door gunner's MG weapons were mounted on swiveling mounts (on a pintle mount) in order to retain and steady the door armament weapon.

Patent Sails, invented in 1819 by William Cubitt, combine the shutters of the Spring Sail with the automatic adjustment of the Roller Reefing Sail. Single Patents have shutters on the trailing side of the sail, Double Patents have shutters on both sides of the sail for its whole length. ;Samson Head An iron collar and plate bearing that fits over the pintle of a post-mill's post, that supports the weight of the crown tree, around which the buck of the mill is constructed. An example is visible at High Salvington windmill.

Huntley, 2004, pp.36–39 Maximum bomb load was , with two additional bombs on underwing racks or with two bombs carried externally under bomb bays and two bombs on underwing racks. The bombs were mounted on hydraulic jacks and were normally released via trap doors; during a dive bombing attack, they were lowered below the surface of the wing. The air gunner of a Battle mans the aircraft's defensive weapon, a single pintle-mounted rapid firing Vickers K machine gun, France, 1940 The bomb aimer position in the Battle was in the aircraft's floor.

The shape of the nozzle extension is such that the ablative liner is retained in the exit cone during transportation, launch and boost. During engine firing, thrust loads force the exit cone liner against the case. The titanium head end assembly which contains the Pintle Injector and propellant valve subcomponents is attached with 36 A-286 steel ¼ inch bolts. In order to keep the maximum operating temperatures of the titanium case in the vicinity of 800°F, the ablative liner was designed as a composite material providing the maximum heat sink and minimum weight.

This was not seen as an issue since normally, the helium release would not occur until after the lunar module was on the Moon, by which time the DPS had completed its operational life and would never be fired again. The design and development of the innovative thrust chamber and pintle design is credited to TRW Aerospace Engineer Gerard W. Elverum Jr. The engine could throttle between and but operation between 65% and 92.5% thrust was avoided to prevent excessive nozzle erosion. It weighed , with a length of and diameter of .

It weighs 95 tonnes, with a box steel section deck, supported by three cables, keeping the overall structural slender. The bridge swings on a pintle bearing, with a central wheel to support its weight. Construction began in August 2007 and the Bridge opened to the public on 20 March 2009, then was officially opened on 2 April 2009, a year behind schedule, by the Mayor of Derby. The bridge, designed by Ramboll, was partly inspired by tailor's shears and has an iconic needle-shaped mast, to echo the heritage of the nearby Silk Mill.

Real Jardín Botánico, CSIC, Madrid It is known by an abundance of common names including snakeshead, adder's root, arum, wild arum, arum lily, lords-and-ladies, devils and angels, cows and bulls, cuckoo-pint, soldiers diddies, priest's pintle, Adam and Eve, bobbins, naked girls, naked boys, starch-root, wake robin, friar's cowl, sonsie-give-us-your-hand, jack in the pulpit and cheese and toast. The name "lords-and-ladies" and other gender- related names refer to the plant's likeness to male and female genitalia symbolising copulation.Brickfields Country Park - Arum Maculatum. Accessed 22 October 2013.

Two 7.62 mm machine guns make up the secondary armament: an electrically fired coaxial machine gun slaved to the main cannon and a second gun on an anti-aircraft pintle installed next to the loader's hatch on the turret. The tank uses an advanced fire-control system developed by Officine Galileo. The commander's station was outfitted with an independently stabilized VS 580-B panoramic day/night sight with an 8x magnification, co-developed with SFIM of France. The sight is housed in an armoured turret located in front of the commander's hatch.

Its armour provided protection against small arms and shrapnel. While US Army M113s were powered by a petrol engine, the Australian Army selected the M113A1 variant which used General Motors V6 diesel engines. This was because the variant had greater range, the diesel fuel was less likely to combust if the APC was damaged in combat and the same engine was used to power buses, which meant that spare parts were readily available. The Australian M113A1s were initially armed with a single pintle- mounted 0.5 inch calibre M2 Browning heavy machine gun.

In high-speed, hard-over turns, the ship barely heeled as the automatic stabilizers engaged. Cyclone was originally armed with two Mk38 25 mm chain guns fore and aft, several pintle mounts for attaching .50 caliber machine guns or Mk 19 grenade launchers, and a position for launching Stinger shoulder-fired SAMs. She and others of her class were upgraded by replacing the after Mk38 mount with the new Mk96 platform which combines a 25 mm chain gun and a 40 mm grenade launcher on a single stabilized platform.

A cut-away drawing of a Coast Artillery battery, showing its two base and stations (upper left), the plotting room (with plotting board), and the directing point (DP) (between the two guns, at right). The directing point, on the surface of the blast apron, is indicated by the red dot. Each gun's displacement (the distance from the pintle center of the gun to the DP) is also indicated.A copper bolt set in concrete marks the DP for the mortars of Battery Whitman at Fort Andrews in Boston Harbor.

A tow ball mounted on the rear of a vehicle A tow hitch (or tow bar) is a device attached to the chassis of a vehicle for towing, or a towbar to an aircraft nose gear. It can take the form of a tow ball to allow swiveling and articulation of a trailer, or a tow pin, or a tow hook with a trailer loop, often used for large or agricultural vehicles where slack in the pivot pin allows similar movements. Another category is the towing pintle used on military vehicles worldwide.

The 12.7 mm DShKM machine gun and the MATIS thermal camera (above the gun barrel) The TR-85M1 tank has two machine guns: #A 12.7×108mm DShKM heavy machine gun in a pintle mount on the loader's hatch ring. The DShK machine gun is made by UM Cugir and can be used as a light antiaircraft weapon. To fire and reload the weapon manually, the gunner has to partially expose himself to suppressive fire. #A 7.62×54mmR PKM machine gun (also made by UM Cugir as the armoured vehicle machine gun version of the md.

Diagram of HH-3E w/ M60D machine guns fitted to the three stations The defensive armament system for the USAF's H-3E helicopters is described as standard to the HH-3E, and capable of being fitted as required to the CH-3E.United States, 1982. p. 4-81 The basic system comprises three M60 machine guns, one each at the forward door, the opposite emergency window, and the rear loading ramp. The forward two positions comprise pintle mounts on skate rails, while the rear loading ramp station comprises a pedestal mount on an armored floor plate.

30–31 Note the prominent housing for the screw jack on the front of the mount and how the forward end of the ammunition car's roof has been slid back The E. u. B. could fire from any suitable section of track after curved wedges were bolted to the track behind each wheel to absorb any residual recoil after the gun cradle recoiled backwards. It also had a pintle built into the underside of the front of the mount. Two large rollers were fitted to the underside of the mount at the rear.

SG-43. The Belgian name Mitrailleuse d'Appui General, or general-purpose machine gun (GPMG), became popular for describing medium machine guns used in multiple roles. The mediums fired full- power rifle-caliber ammunition, but had some concessions for more extended firing and more general usage. This generally included both bipod and tripod/pintle mounting options and quick-change barrels. Water-cooled machine guns of the same caliber as the existing mediums were no longer useful, as the situation in which they excelled (non-stop firing) was regarded as no longer being needed in modern warfare.

The frames of windows were hewn from a single heavy piece of wood and offered plenty of "meat" into which a heavy pintle could be driven. The rails of the shutter were often six or eight inches high and provided plenty of room to position the strap hinge across the width of the shutter. The hinges were fastened to the shutters with rivets or nails driven through and clinched on the inside of the closed shutter. The nails and rivets were not only strong and secure, but they were also the cheapest fastener option.

Some of the more common Urutu variants replaced the Browning heavy machine gun with a single turret or pintle-mounted 7.62mm general- purpose machine gun. Depending on the size of the turret ring, it was also possible to fit heavier turrets carrying gun-mortars or low-pressure cannon for direct fire support. Transmission consists of an Allison MT-643 automatic gearbox with five forward and one reverse gear ratios. Early Brazilian Army Urutus used either a Clark manually operated gearbox with the same gear pattern or a manual Mercedes-Benz 63/40 gearbox.

In 1938, Manville introduced a twelve round gun with a 37mm (1.5-inch) bore. This version fired 37mm × 5.5 inch Long (37mm × 127mmR) flare, smoke, or tear gas shells and was designed for police and security use. It was meant to be used in an indirect fire mode and had its barrel mounted at the bottom of the cylinder rather than the top. Its greater weight prohibited its use by any but the strongest of men, since it was designed to be fired from a tripod or pintle mount.

Weaponry varies by a very wide degree between AFVs – lighter vehicles for infantry carrying, reconnaissance or specialist roles may have only a Cannon or Machine gun (or no armament at all), whereas heavy self propelled artillery will carry large guns, mortars or rocket launchers. These weapons may be mounted on a pintle, affixed directly to the vehicle or placed in a turret or cupola. The greater the recoil of the weapon on an AFV, the larger the turret ring needs to be. A larger turret ring necessitates a larger vehicle.

Additional armament of the Ikv 91 included two 7.62 mm Browning machine guns; one in a coaxial mounting, and the second on a pintle attached to the commander's cupola. Two 71 mm Lyran flare mortars were mounted on the turret along with a set of smoke dischargers (usually 12). The vehicle was equipped with a laser rangefinder, night vision and a computerised fire- control system for increased first-round hit probability. The Ikv 91 fired at a rate of 8 rounds per minute and 59 rounds of 90 mm ammunition were carried internally.

The Ratel's steering system is mechanical, with hydraulic assistance. One of the unique features of the Ratel's design was the pintle-mounted machine gun at the hull rear, which was used for anti-aircraft purposes by the vehicle crew. Ratel turrets are located towards the front of the vehicle, directly behind the driving compartment, and house two crew members: the section commander to the left and the turret gunner to the right. Both crew members are provided with roof hatches; the commander is also afforded a domed cupola with vision blocks.

Kestrel was a LOX/RP-1 pressure-fed rocket engine, and was developed by SpaceX as the Falcon 1 rocket's second stage main engine. It was built around the same pintle architecture as SpaceX's Merlin engine but does not have a turbo-pump, and is fed only by tank pressure. Its nozzle was ablatively cooled in the chamber and radiatively cooled in the throat, and is fabricated from a high strength niobium alloy. Thrust vector control is provided by electro-mechanical actuators on the engine dome for pitch and yaw.

FV105 Sultan is a British Army command and control vehicle based on the CVR(T) platform. It has a higher roof than the armoured personnel carrier variants, providing a more comfortable "office space" inside. This contains a large vertical map board and desk along one side, with a bench seat for three people facing it. Forward of this are positions for the radio operator, with provision for four radios, and vehicle commander, whose seat can be raised to give him access to the pintle-mounted general purpose machine gun.

The various Silverados, Tahoes, and Suburbans that are used provide numerous platforms for different kinds of vehicles. As GM has redesigned its civilian trucks and SUVs from 2001–present, LSSVs have also been updated cosmetically. The Militarization of standard GM trucks/SUVs to become LSSVs includes exterior changes such as CARC paint (Forest Green, Desert Sand, or 3-color Camouflage), blackout lights, military bumpers, a brush guard, a NATO slave receptacle/NATO trailer receptacle, a pintle hook and tow shackles. The electrical system is changed to the 24/12 volt military standard.

A typical weapon installation could be a 7.62mm machine gun forward plus a pedestal mount for a missile launcher or a 40 mm automatic grenade launcher such as the 40AGL. The STK 50 heavy machine gun can also be mounted. Some vehicles in service with the Singapore Army carry a rear-mounted pedestal for two Spike anti-tank guided weapons (ATGW), with stowage for five missiles. Others have been seen with a combined 40 mm AGL and 7.62 mm machine gun mounting supplemented by a pintle-mounted 7.62 mm machine gun, while others have been seen mounting the MILAN ATGW.

An electrically fired vent tube is used to initiate firing of the main armament rounds. (The main armament ammunition is thus described to be "three-part ammunition", consisting of the projectile, charge and vent tube.) The separation of ammunition pieces also aids in ensuring lower chances of ammunition detonation. The Challenger 2 is also armed with a L94A1 EX-34 7.62 mm chain gun coaxially to the left of the main gun, and a 7.62 mm L37A2 (GPMG) machine gun mounted on a pintle on the loader's hatch ring. 4,200 rounds of 7.62 mm ammunition are carried.

Other improvements have also been considered, including a regenerative NBC protection system. In addition, several Challenger 2s had the pintle-mounted GPMG on the loader's crew hatch replaced with a remote controlled turret, allowing the loader to operate the weaponry without having to expose himself to enemy fire. In May 2007, the Ministry of Defence's Future Systems Group invited BAES to tender for the Challenger 2 Capability Sustainment Program (C2 CSP), which combined all upgrades into one programme. However, by mid-2008, the programme was in danger of slipping, or even being cancelled, as a result of defence budget shortfalls.

Known as the AML HE 60-20, the AML 60-20 replaced both co-axial 7.62mm machine guns with an M621 20 mm autocannon with 500 stored rounds. The 20 mm autocannon was based on the MG 151 and has an elevation of +50° and a depression of −8°, allowing it to engage low-flying aircraft as necessary. It fires both armour-piercing and high-explosive rounds with a muzzle velocity of . An optional 7.62mm pintle-mounted machine gun can be mounted on the turret roof as necessary, although only 1,000 rounds of ammunition may be stored.

In 2012 Dasher and Pursuer were replaced by Raider and Tracker - these can be identified by a number of pintle-mounted L7 7.62 mm GPMG machine guns and armour plating. and were also formerly allocated to the Gibraltar Squadron for guard ship and search and rescue duties, but were replaced by the dedicated Scimitar class. These two ships were also used during the Thames River Pageant, escorting the Royal Barge during the Queens Diamond Jubilee. Unlike the remainder of the class, both these ships remain capable of being mounted with a 20 mm cannon on the fo'c'sle.

It was assembled with the aid of a derrick or crane, which took between three and five days, and railroad tracks were laid slightly past the firing platform to accommodate the front bogies of the gun. The gun was moved over the firing platform and then lowered into position after the central section of rail was removed. After the gun's pintle was bolted to the firing platform's pivot mount, the entire carriage was jacked up so that the trucks and their sections of rail could be removed. The carriage was then lowered so that the rear rollers rested on the outer track.

In the late production vehicles, the heavy machine gun was replaced with two M1919A4 .30 MGs on pintle mounts and one more in the bow mount. 1,890 units produced, and 1,307 were transferred to US Army and 50 to British Army. The Chinese PLA captured several from Nationalist forces during the Civil War and placed them in service, eventually modifying some by replacing the 75 mm howitzer with the 37 mm M6 tank gun and others with the ZiS-2 57 mm anti-tank gun, complete with shield, the conversion also necessitating the removal of the original mantlet.

Another thing to watch out for is the casing width – it may be too tight for a plate pintle. If it is narrow and deep, the offset on the hinge will need to be nearly 90° to keep the hinge from binding on the corner of the structure. Speaking of deep offsets, when you get into stone and you're looking at 8- to 10-inch offsets, that's an awful lot of foot-pounds of pull on wood and fasteners. You may want to consider going to shutters that fit the masonry opening and mounting the pintles to the masonry.

The Coyotes mount a 25×137mm M242 Bushmaster chain gun and two 7.62×51mm NATO C6 general purpose machine guns. One of the machine guns is mounted coaxial to the main gun while the other is pintle-mounted in front of the crew commander's hatch. The main gun is equipped with dual ammunition feeds that allow for separate weapons effects, selectable by the gunner/crew commander; the standard load is a belt of armour-piercing sabot rounds and a belt of HE-T explosive/fragmentation rounds. The main gun and coax machine gun are 2-axis stabilized.

The hatch for the vehicle commander is directly behind the driver's; a pintle mount next to it can take a machine gun. There is a side-hinged door in the rear for loading and unloading, and in most models a large split-hatch round opening in the passenger compartment roof. In common with other such old designs, there are no firing ports for the troops carried - British Army doctrine has always been to dismount from vehicles to fight. There is a wading screen as standard, and the vehicle has a water speed of about 6 km/h when converted for swimming.

In 1987, Chevrolet started building a new generation of CUCV. The US Air Force initially bought small batches of these units, dubbed the CUCV II. Produced through 2001, CUCV IIs were basic civilian Chevrolet C/K, Tahoe, and Suburban units sent to another plant for "militarization" on special order. The trucks were originally white in color with gray vinyl interiors. They received CARC exterior paint (Forest Green, Desert Sand, or 3-color camouflage), a brush bar, a pintle hitch, towing/loading shackles, extra leaf springs to give them a 5/4 ton rating and a host of other small changes.

The inside of a kiln, looking up to the cowlClose Brewery, Hadlow, KentThis section deals with the traditional cowls found on oasts, with particular reference to the South East. From the outside, a cowl appears to just sit on the roof of the kiln. High in the roof of the kiln is a beam spanning the centre, called the sprattle beam, this carries a bearing which the pintle on the bottom of the centre post sits in. At the top of the kiln, the centre post passes through a two or three armed top stay iron.

Rhodesian "Crocs" were usually armed with a FN MAG-58 7.62mm Light Machine Gun (LMG), sometimes installed on a locally produced one-man MG armoured turret to protect the gunner. Vehicles assigned to convoy escorting duties ('E-type') had a Browning M1919A4 7.62mm medium machine gun mounted on an open-topped, cylinder-shaped turret (dubbed 'the dustbin') whilst those employed on 'externals' received a tall, square-shaped and fully enclosed MAG turret mounted on the roof over the commander's seat.Locke & Cooke, Fighting Vehicles and Weapons of Rhodesia 1965-80 (1995), p. 45. The Zimbabwean vehicles after 1980 sported pintle-mounted Soviet-made 12.7mm and 14.5mm Heavy Machine Guns (HMG) instead.

As GM has periodically redesigned its civilian trucks and SUVs from 2001 to the present, LSSVs have also been updated cosmetically. The militarization of standard GM trucks/SUVs to become LSSVs includes exterior changes such as CARC paint (Forest Green, Desert Sand, or 3-color Camouflage), blackout lights, military bumpers, a brush guard, a NATO slave receptacle/NATO trailer receptacle, a pintle hook, tow shackles and a 24/12 volt electrical system. The dashboard has additional controls and dataplates. The truck also can be equipped with weapon supports in the cab, cargo tie down hooks, folding troop seats, pioneer tools, winches, and other military accessories.

Unlike in antiquity, the foresail was adopted on medieval two-masters after the mizzen, evidence for which dates to the mid-14th century. To balance out the sail plan the next obvious step was to add a mast fore of the main-mast, which first appears on a Catalan vessel from 1409. With the three-masted ship established, propelled by square rig and lateen, and guided by the pintle-and-gudgeon rudder, all advanced ship design technology necessary for the great transoceanic voyages was in place by the onset of the 15th century.Mott, Lawrence V. (1994): "A Three-masted Ship Depiction from 1409", The International Journal of Nautical Archaeology, Vol.

Multi-start operation is adjustable up to 55.6 kN and propellant throughput up to 7,711 kg; and the engine can be adapted to optional expansion ratio nozzles. Development of the innovative thrust chamber and pintle design is credited to TRW Aerospace Engineer Gerard W. Elverum Jr. The combustion chamber consists of an ablative- lined titanium alloy case to the 16:1 area ratio. Fabrication of the 6Al4V alloy titanium case was accomplished by machining the chamber portion and the exit cone portion from forgings and welding them into one unit at the throat centerline. The ablative liner is fabricated in two segments and installed from either end.

As an anti-aircraft weapon it was mounted on pintle and tripod mounts, and on a triple mount on the GAZ-AA truck. Late in the war, it was mounted on the cupolas of IS-2 tanks and ISU-152 self-propelled guns. As an infantry heavy support weapon it used a two-wheeled trolley which unfolded into a tripod for anti-aircraft use, similar to the mount developed by Vladimirov for the 1910 Maxim gun. It was also mounted in vehicle turrets, for example, in the T-40 light amphibious tank. In 1946, the DShK 1938/46 or DShKM (M for modernized) version was introduced.

TRW changed the pintle injector configuration three times during testing to explore the engine's performance envelope; engineers also replaced the ablative chamber once while the engine was on the test stand—demonstrating the LCPE's ease of operation. Test results demonstrated that the engine was stable over a wide variety of thrust levels and propellant ratios. Development of the engine was temporarily discontinued with the cancellation of the Space Launch Initiative. In 2002 TRW was acquired by Northrop Grumman and development of a LOX/RP-1 engine (TR-107) continued, under contract to NASA, for potential use on next-generation launch and space transportation vehicles.

Two different vehicle designs were designed for the XM800 project, Lockheed's XM800W unconventional articulated 6 × 6 wheeled armored car and FMC's XM800T tracked version. Both models initially featured the same turret with the US-built version of the Hispano-Suiza HS.820 20 mm autocannon, the M139, as the primary weapon, as well as a M60-derived machine gun on a pintle mount. The M139 had been selected for all of the MICV projects. The XM800W was later equipped with a new turret design that kept the M139 cannon, but that had an upper cover that flipped forward to form a gun shield, or rearward to close up.

Seven cars could carry a portable metal firing platform (Bettungslafette) that had a central pivot mount and an outer rail. It was assembled with the aid of a derrick or crane, which took between three and five days, and railroad tracks were laid slightly past the firing platform to accommodate the front bogies of the gun. The gun was moved over the firing platform and then lowered into position after the central section of rail was removed. After the gun's pintle was bolted to the firing platform's pivot mount, the entire carriage was jacked up so that the trucks and their sections of rail could be removed.

The motorcycles used in the chase from the castle were a mixed bag: the scout model with sidecar in which Indy and Henry escape was an original Dnepr, complete with machine gun pintle on the sidecar, while the pursuing vehicles were more modern machines dressed up with equipment and logos to make them resemble German army models. Gibbs used Swiss Pilatus P-2 army training planes standing in for Messerschmitt Bf 109s. He built a device based on an internal combustion engine to simulate gunfire, which was safer and less expensive than firing blanks. Baking soda was applied to Connery to create Henry's bullet wound.

The designer was Václav Holek, a gun inventor and design engineer. In the 1950s, many Bren guns were re-barrelled to accept the 7.62×51mm NATO cartridge and modified to feed from the magazine for the L1 (Commonwealth version of the FN FAL) rifle as the L4 light machine gun. It was replaced in the British Army as the section LMG by the L7 general-purpose machine gun (GPMG), a heavier belt-fed weapon. This was supplemented in the 1980s by the L86 Light Support Weapon firing the 5.56×45mm NATO round, leaving the Bren gun in use only as a pintle mount on some vehicles.

From the age of discovery onwards, European ships with pintle-and- gudgeon rudders sailed successfully on all seven seas.Lawrence V. Mott, The Development of the Rudder, A.D. 100-1600: A Technological Tale, Thesis May 1991, Texas A&M; University, S.118f. Many historians' consensus considered the technology of stern-mounted rudder in Europe and Islamic World, which was introduced by travelers in the Middle Ages, was transferred from China. However, Lawrence Mott in his master thesis stated that the method of attachment for rudders in the Chinese and European worlds differed from each other, leading him to doubt the spread of the Chinese system of attachment Lawrence V. Mott, p.

In navigation, the foundation to the subsequent age of exploration was laid by the introduction of pintle-and-gudgeon rudders, lateen sails, the dry compass, the horseshoe and the astrolabe. Significant advances were also made in military technology with the development of plate armour, steel crossbows and cannon. The Middle Ages are perhaps best known for their architectural heritage: While the invention of the rib vault and pointed arch gave rise to the high rising Gothic style, the ubiquitous medieval fortifications gave the era the almost proverbial title of the 'age of castles'. Papermaking, a 2nd-century Chinese technology, was carried to the Middle East when a group of Chinese papermakers were captured in the 8th century.

Therefore, it was decided to design two vehicles. The first one was supposed to satisfy the immediate need of a new airborne IFV by modifying the BMD-1/BMP-1 turret, arming it with the same armament as the one on the BMP-2 and then fitting it onto the BMD-1 hull. The second vehicle was supposed to be much bigger to allow fitting of the BMP-2 turret and later became the BMD-3. The modernized variant of BMD-1 was developed in 1983 and incorporated the new B-30 turret armed with 30 mm 2A42 multi-purpose autocannon, 7.62 mm PKT coaxial tank machine gun and pintle-mounted 9P135M-1 ATGM launcher.

As GM has periodically redesigned its civilian trucks and Sport Utility Vehicles (SUVs) from 2001 to the present, LSSVs have also been updated cosmetically. The militarization of standard GM trucks/SUVs to become LSSVs includes exterior changes such as Chemical Agent Resistant Coating (CARC) paint (Forest Green, Desert Sand, or 3-color Camouflage), blackout lights, military bumpers, a brush guard, a NATO slave receptacle/NATO trailer receptacle, a pintle hook, tow shackles and a 24/12 volt electrical system. The dashboard has additional controls and dataplates. The truck also can be equipped with weapon supports in the cab, cargo tie down hooks, folding troop seats, pioneer tools, winches, and other military accessories.

The "pintle ball", a vital piece of equipment for the Chouteau Lock, was found to be damaged and in need of total replacement during a routine dewatering of the lock in 2009. This required obtaining an identical replacement, dewatering the lock again, lifting the gate, removing the old ball and installing its replacement, then refilling the lock Such an operation had never been attempted by the Tulsa District of the U.S. Army Corps of Engineers (ACE). Complicating the operation was the fact that there were no plans or drawings to show how the work should be done, and there were no spare pintal ball parts available. The replacement would have to be designed and constructed anew.

This is the base hull of the LFV-90 Dragoon vehicle (see US light combat vehicles). The hull has some modifications to better suit it for use as an armored personnel carrier, and may have a pintle mount or one of several turrets. The basic APC version is used, in addition to military forces, by several police forces in the US, often with a ramming pole welded to the nose of the vehicle. The Personnel Carrier is the base vehicle of the line, with two hatches in the front deck for the commander and gunner, a center hatch with a weapon mount directly behind those hatches for the gunner, and a large sliding hatch on the rear deck for the passengers.

STL proposed an engine that was gimbaled as well as throttleable, using flow control valves and a variable-area pintle injector, in much the same manner as does a shower head, to regulate pressure, rate of propellant flow, and the pattern of fuel mixture in the combustion chamber. The first full-throttle firing of Space Technology Laboratories' LM descent engine was carried out in early 1964. NASA planners expected one of the two drastically different designs would emerge the clear winner, but this did not happen throughout 1964. Apollo Spacecraft Program Office manager Joseph Shea formed a committee of NASA, Grumman and Air Force propulsion experts, chaired by American spacecraft designer Maxime Faget, in November 1964 to recommend a choice, but their results were inconclusive.

The basic vehicle, which could be readied for wading in approximately five minutes, has a water speed of about 6 km/h when converted for swimming and was propelled by its tracks. Most of these vehicles have had their amphibious capability removed. FV432s in service with infantry battalions are equipped with a pintle-mounted L7 GPMG (if not fitted with the Peak Engineering turret). Vehicles with the Royal Artillery, Royal Engineers and Royal Signals were originally fitted with the L4A4 variant of the Bren light machine gun, but they now use the GPMG. When equipped with the GPMG, the vehicle carries 1,600 rounds of belted 7.62mm ammunition; when carrying the Bren LMG, the vehicle carried 1,400 rounds of 7.62mm ammunition (50 magazines, each holding 28 rounds).

Prototype The M205 Lightweight Tripod for Heavy Machine Guns is the replacement for the current M3 tripod in support of the M2 machine gun and Mk 19 grenade launcher used in the United States armed forces. The soldier will experience less weight burden with the M205 Lightweight Tripod than with the standard M3 Tripod (, including the pintle and T&E;), and will be able to take advantage of the enhanced tripod's integrated traverse and elevation mechanism for quicker, more accurate target engagement. Not only is the M205 (34 lbs) lighter than the M3 by over 16 lbs (33%), it is stronger and provides a more stable (lower dispersion) firing platform than the M3. The M205 was first fielded by the 1st Armored Division in November 2013.

The term "medium machine gun" is used to refer to the ubiquitous full-power rifle-caliber machine gun designs, which are alternatively called general-purpose machine guns or universal machine guns. M240G (foreground) and an Iraqi PKM (background) They essentially all have provisions for quick-change barrels and the ability to be fired from a bipod, tripod, or pintle mount, and weigh between 20-30 pounds. Modern Western MMG/GPMG weapons almost always fire 7.62×51mm full-power rifle ammunition; modern Eastern MMG/GPMG weapons usually fire 7.62×54mmR full-power rifle ammunition with a rimmed cartridge. For example, the US Army and Marines now use the FN MAG (as the M240 machine gun), which is generally called the "M240 medium machine gun".

Standard LAV fitted with a turret with 360° traverse, armed with an M242 25 mm chain gun with 420 rounds of 25 mm ammunition, both M791 APDS-T (Armour Piercing Discarding Sabot-Tracer) and M792 HEI-T (High Explosive Incendiary- Tracer), of which half is ready for use. One hundred fifty rounds are ready for use from one stowage bin, 60 from another stowage bin, the other 210 rounds are stowed elsewhere in the vehicle. A coaxial M240C machine gun is mounted alongside the M242, and a pintle-mounted M240B/G machine gun, with 1,320 rounds of 7.62 mm ammunition, is mounted on the turret roof. The Canadian Army uses an upgraded version of this chassis for its Coyote Armoured Reconnaissance Vehicle.

In 1917 the 1Z truck was selected as the carrier for 75/26 A.V. guns to form self-propelled anti-aircraft artillery; designated Autocannone da 75/27 A.V., the weapon system consisted of an anti-aircraft gun permanently installed in the bed of a partially armored 1Z. The pintle mounted 75/26 A.V. (Anti Velivolo, anti-aircraft) was based on the 75/27 Mod. 1906 field gun modified for use in the anti-aircraft role. The initial order of 50 guns was later halved to 25, to form six mobile batteries (Autobatterie) which were delivered in summer 1918; the experiment was short lived, as the weapon did not prove satisfactory in the field and the guns were soon dismounted to be used in static positions.

A requirement for a lighter scout vehicle also started at the same time, accepting two different proposals for the XM800 Armored Reconnaissance Scout Vehicle, one tracked, one wheeled. All of the vehicles were equipped with a similar turret armed with the M139 20 mm cannon (a licensed version of the Hispano-Suiza HS.820) and an M60-derived machine gun on a pintle mount. FMC continued work on their own in spite of losing the MICV contest, and started work on a private project known as the XM765 Armoured Infantry Fighting Vehicle based on the M113 machinery and generally similar to the XM734 but with thicker armor and sloping it wherever possible. Although the AIFV would go on to see a number of international sales, the Army rejected it for a variety of reasons.

The preceding technology innovations enabled the first exoatmospheric kinetic kill of a simulated reentry warhead off Kwajalein atoll on 28 January 1991 on the first flight of ERIS. In the late '90s, FSO pintle injectors were used with gelled propellants, which have a normal consistency like that of smooth peanut butter. Gelled propellants typically use either aluminum powder or carbon powder to increase the energy density of the liquid fuel base (typically MMH) and they use additives to rheologically match the oxidizer (typically IRFNA based) to the fuel. For gelled propellants to be used on a rocket, face shutoff is mandatory to prevent dry-out of the base liquid during off times between pulses, which would otherwise result in the solids within the gels plugging the injector passages.

The initial prototype, the Mark I, made its first appearance in January 1925 and spent the next year undergoing trials and taking part in manoeuvres, mainly with 28 Battery, 9th Field Brigade, Royal Artillery. The lone Mark I was transferred to 20 Battery, 9th Field Brigade RA, who then took delivery of three Mark II Birch Guns in July 1926, followed by a fourth gun in September. Improvements included changes to the gun and (very complex) sighting equipment: the top-mounted recuperator was moved below the barrel and a gun shield provided for crew protection. In all five vehicles the gun was pintle-mounted towards the front of the vehicle and had a 360 degree traverse and a maximum elevation of almost 90 degrees, allowing them to be used as anti-aircraft artillery.

BMD-2 of the 106th Guards Airborne Division The vehicle is armed with stabilized 30 mm 2A42 multi- purpose autocannon and 7.62 mm PKT coaxial tank machine gun (mounted on the right hand side of the main gun). The vehicle carries 300 rounds for the main gun (180 AP and 120 HE) and 2,940 rounds for the machine gun. The main gun can be elevated or depressed between 75° and -5° and can be used to fire at air targets. The turret is also armed with pintle-mounted 9P135M-1 ATGM launcher, on the right hand side of the roof of the turret, with semi-automatic control capable of firing SACLOS guided 9M113 "Konkurs" (AT-5 Spandrel), 9M113M "Konkurs-M" (AT-5B Spandrel B), 9M111 "Fagot" (AT-4 Spigot) and 9M111-2 "Fagot" (AT-4B Spigot B) ATGMs.

Unlike other Rhodesian armoured vehicles however, they were not protected against landmines. Nicknamed the 'Pig', the first vehicle was an exact copy of the original design, having an all-welded body with a fully enclosed troop compartment. The second 'Pig' differed slightly, having a raised roof over the driver and commander seats, a rear door and an open-top troop compartment at the back, which allowed provision for three FN MAG-58 7.62×51mm NATO light machine guns to be installed on pivot mounts mounted on the vehicle's inner side walls. For additional firepower, the vehicles were often armed with twin AN/M2 aircraft machine guns (12.7×99mm) or modified British Hispano Mk.V 20mm autocannons taken from decommissioned Rhodesian Air Force de Havilland Vampire Mk9 single-seater fighter jets and mounted on a pintle fitted with a gun shield to protect the gunner.

The dolly is equipped with a fifth wheel to which the trailer is coupled. Because the dolly attaches to a pintle hitch on the truck, maneuvering a trailer hooked to a dolly is different from maneuvering a fifth wheel trailer. Backing the vehicle requires same technique as backing an ordinary truck/full trailer combination, though the dolly/semi setup is probably longer, thus requiring more space for maneuvering. The tractor/semi-trailer configuration is rarely used on timber trucks, since these will use the two big advantages of having the weight of the load on the drive wheels, and the loader crane used to lift the logs from the ground can be mounted on the rear of the truck behind the load, allowing a short (lightweight) crane to reach both ends of the vehicle without uncoupling.

Osceola, WI: Motorbooks International, 1992 All of these early M60s eventually had the M19 cupola and M85 machine gun installed. Compared to a conventional pintle mount, the remote-controlled M85 machine gun was relatively ineffective in the anti-aircraft role for which it was designed. Removing the cupola lowered the vehicle's relatively high silhouette. The cupola's hatch also opened toward the rear of the vehicle and was dangerous to close if under small-arms fire owing to a lock-open mechanism that required the user to apply leverage to unlock it prior to closing. The commander was able to observe the battlefield using the x4 binocular M34D daylight vision block or the M19E1 IR or M36 Passive Periscopes while remaining under armor protection with a 360 degree traverse independent of the turret, was stabilized in azimuth and elevation and carried 600 rounds of ammunition.

Pintle-and-gudgeon stern-post rudder of the Hanseatic league flagship Adler von Lübeck (1567–1581).The Periplus of the Erythraean Sea, a document dating from 40–60 AD, describes a newly discovered route through the Red Sea to India, with descriptions of the markets in towns around Red Sea, Persian Gulf and the Indian Ocean, including along the eastern coast of Africa, which states "for beyond these places the unexplored ocean curves around toward the west, and running along by the regions to the south of Aethiopia and Libya and Africa, it mingles with the western sea (possible reference to the Atlantic Ocean)". European medieval knowledge about Asia beyond the reach of the Byzantine Empire was sourced in partial reports, often obscured by legends,Arnold 2002, p. xi. dating back from the time of the conquests of Alexander the Great and his successors.

Its 30 mm 2A42 multi-purpose autocannon with two-belt loading system and very high elevation angle solved some of the serious drawbacks of the 73 mm 2A28 "Grom" gun. Also the 9S428 ATGM launcher was replaced by pintle-mounted 9P135M-1 ATGM launcher with semi-automatic control capable of firing SACLOS guided 9M113 "Konkurs" (AT-5 Spandrel), 9M113M "Konkurs-M" (AT-5B Spandrel B), 9M111 "Fagot" (AT-4 Spigot) and 9M111-2 "Fagot" (AT-4B Spigot B) ATGMs which proved to be much more effective and reliable than the MCLOS guided 9M14 "Malyutka" (AT-3 Sagger), 9M14M "Malyutka-M" (AT-3B Sagger B) and 9M14P "Malyutka-P" (AT-3C Sagger C) ATGMs. Because of that the high command of Soviet airborne forces decided to arm their units with similar vehicles. In the beginning it became obvious that the hull of BMD-1 was too small for the BMP-2 turret.

Originally armed with two Mk38 25 mm chain guns fore and aft, several pintle mounts for attaching .50 caliber machine guns or Mk 19 grenade launchers, and a position for launching Stinger shoulder-fired SAMs (although this was removed when the ship was transferred to the Philippine Navy and is currently unavailable), the ship, along with others of her class still in the US Navy, were upgraded early on by replacing the after Mk.38 mount with the new Mk.96 platform. The Mk.96 combines both a M242 Bushmaster 25 mm chain gun and a 40 mm automatic grenade launcher on a single stabilized platform. The Mk.96 features an electro-optical fire control system with 27x zoom, infrared and low-light modes, a laser rangefinder, and an array of environmental sensors, which feed data into the ballistics computer to produce an accurate firing solution even while maneuvering at high speed.

Junks employed stern-mounted rudders centuries before their adoption in the West for the simple reason that Western hull forms, with their pointed sterns, obviated a centreline steering system until technical developments in Scandinavia created the first, iron mounted, pintle and gudgeon 'barn door' western examples in the early 12th century CE. A second reason for this slow development was that the side rudders in use were, contrary to a lot of very ill-informed opinion, extremely efficient. Thus the junk rudder's origin, form and construction was completely different in that it was the development of a centrally mounted stern steering oar, examples of which can also be seen in Middle Kingdom (c.2050–1800 BCE) Egyptian river vessels. It was an innovation which permitted the steering of large ships and due to its design allowed height adjustment according to the depth of the water and to avoid serious damage should the junk ground.

The voyage was not without difficulty and sailing through the aftermath of a gale caused conditions that saw th bow door start to "peel" externally, some engine troubles that caused a close-down on one side, one rudder pintle breaking, and the helm-wheel shake to pieces leaving only its steel skeleton. Eventually the vessel had to get towed to Sydney by the accompanying LSM, and attaching the towing bridle in heavy seas resulted in an accident that injured two of the six crew. This unhappy voyage ended with the vessel coming into Sydney Harbour with distress flags/balls hoisted, having to steer in a slow circle to port then a short burst of full astern, in an attempt to get it to dock alongside Clifton Gardens base. That the vessel was largely orange with rust by this time (and no longer bronze deep green) also did little to impress the official greeting party as news of the vessels mishaps had not been passed because of radio failure during the voyage.

It entered production in 1951. Its main gun was the M36 90 mm gun with an M12 optical rangefinder fitted. The secondary armament consisted of two .30 cal Browning machine guns, one in the bow and one coaxial with the 90mm main gun in the turret, and a .50 caliber Browning M2 on a pintle mount on the turret roof. The M47 was the last American-designed tank to include a bow machine gun. The T42 turret had a larger turret ring than the M26/M46 turret, and featured a needle-nose design, which improved armor protection of the turret front, an elongated turret bustle and storage bin which protruded halfway across the engine deck, and sloped sides to further improve ballistic protection; this gave the turret a decidedly lozenge-shaped profile. It also featured the M12 stereoscopic rangefinder, which was designed to improve first-round hit probability but proved difficult to use; the rangefinder protruded from both sides of the upper turret front, which would be a feature of American tanks until the advent of the M1 Abrams in 1980.

Before it was used, a Whistler-Hearn board had to be set up and customized to the geography of the area at which it was to be used and for the location of the guns in the battery it was to direct. First, the primary block (representing the primary base end station) was slid onto the bronze base-line arm (that extended all the way across the bottom diameter of the table) and secured at the exact center of that arm. Then, the secondary block (representing the secondary base end station) was slid onto the left or right end of the base-line arm (depending of the layout of the site) and set at a distance from the primary block that was equal to the (scaled) length of the base line at that site. Both the primary and the secondary block had a pintle, or pin, attached to it which represented (on the board) the surveyed position of the observing instrument in the primary or secondary base end station.

Various furnishings were normally provided to aid in its use as a utility rotorcraft, such as an internal winch mounted within the forward cabin, which can be used to assisting loading by pulling external cargo on pallets into the aircraft via the ramp and rollers, and an optionally-attached belly-mounted cargo hook, which would be usually rated at for carrying cargoes externally underneath the Sea Knight; despite the hook having been rated at , this was safety restricted to less payload as they got older. When operated in a typical configuration, the CH-46 would usually be operated by a crew of three; a larger crew could be accommodated when required, which would be dependent upon mission specifics. For example, a search and rescue (SAR) variant would usually carry a crew of five (Pilot, Co-Pilot, Crew Chief, Swimmer, and Medic) to facilitate all aspects of such operations. For self-defense, a pintle-mounted 0.50 in (12.7 mm) Browning machine gun could be mounted on each side of the helicopter.

It was envisaged and well developed to provide portable light and medium machine gun infantry cover, anti-aircraft coverage, and even sniping ability. Equipped with a quick-change barrel and fed either with non-disintegrating metallic-link belts, or from a 50-round Gurttrommel (belt drum) or a 75-round spring-loaded saddle-drum Patronentrommel 34 magazines (with a simple change of the feed cover for a Trommelhalter magazine holder), the MG 34 could sustain fire for much longer periods of time than other portable squad-level weapons such as the American B.A.R. and the British Bren Gun, both of which were fed by box magazines, while also being much lighter and more portable than crew-served weapons like the Browning M1919 or Vickers machine guns (which also lacked quick-change barrels). The MG 34 was also quite versatile; not only was it able to be fed from belted ammunition or a saddle drum magazine, it could also be fired from a bipod, an innovative Lafette 34 tripod or various pintle mounts for armored vehicles. Switching between a bipod and a tripod required no special tools, as the mounting latch was spring-loaded.

The rearward-retracting nosewheel strut on the Heinkel He 219 and the forward-retracting nose gear strut on the later Cessna Skymaster similarly rotated 90 degrees as they retracted. On most World War II single-engined fighter aircraft (and even one German heavy bomber design) with sideways retracting main gear, the main gear that retracted into the wings was meant to be raked forward, towards the aircraft's nose in the "down" position for better ground handling, with a retracted position that placed the main wheels at some angle "behind" the main gear's attachment point to the airframe – this led to a complex angular geometry for setting up the "pintle" angles at the top ends of the struts for the retraction mechanism's axis of rotation, with some aircraft, like the P-47 Thunderbolt and Grumman Bearcat, even mandating that the main gear struts lengthen as they were extended down from the wings to assure proper ground clearance for their large four-bladed propellers. One exception to the need for this complexity in many WW II fighter aircraft was Japan's famous Zero fighter, whose main gear stayed at a perpendicular angle to the centerline of the aircraft when extended, as seen from the side.
