GSh-30-6
The Gryazev-Shipunov GSh-6-30 (Russian: Грязев-Шипунов ГШ-6-30) is a Russian 30 mm rotary cannon aircraft-mounted and naval autocannon used by Soviet and later CIS military aircraft. The GSh-6-30 fires a 30×165mm, projectile. Description The GSh-6-30, designed in the early 1970s and entering service in 1975, has a six barrel design that is similar to the Gryazev-Shipunov GSh-6-23. It was based on the naval AO-18 used in the AK-630 system. Unlike most modern rotary cannons, it is gas-operated rather than hydraulically driven, allowing it to "spin up" to maximum rate of fire more quickly, allowing more rounds to be placed on target in a short-duration burst. This makes the weapon advantageous in dogfights, where pilots often have a very small window for engaging the enemy. Ignition is electrical, as with the smaller GSh-6-23. On the MiG-27 "Flogger" the GSh-6-30 had to be mounted obliquely to absorb recoil. The gun was noted for its high (often uncomfortable) ...

Rotary Cannon
A rotary cannon, rotary autocannon, rotary gun or Gatling cannon, is any large- caliber multiple-barreled automatic firearm that uses a Gatling-type rotating barrel assembly to deliver a sustained saturational direct fire at much greater rates of fire than single-barreled autocannons of the same caliber. The loading, firing and ejection functions are performed simultaneously in different barrels as the whole assembly rotates, and the rotation also permits the barrels some time to cool. The rotating barrels on nearly all modern Gatling-type guns are powered by an external force such as an electric motor, although internally powered gas-operated versions have also been developed. The cyclic multi-barrel design synchronizes the firing/reloading sequence. Each barrel fires a single cartridge when it reaches a certain position in the rotation, after which the spent casing is ejected at a different position and then a new round is loaded at another position. During the cycle, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases ( ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. In hand-held small arms, the recoil momentum will be eventually transferred to the ground, but will do so through the body of the shooter hence resulting in a noticeable impulse commonly referred to as a "kick". In heavier mounted guns, such as heavy machine guns or artillery pieces, recoil momentum is transferred to the Earth's surface through the platform on which the weapon is mounted. In order to bring the rearward moving gun to a halt, the momentum acquired by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakushev-Borzov YakB-12
The Yakushev-Borzov YakB-12.7 mm is a remotely controlled 12.7×108mm caliber four-barrel rotary cannon developed by the Soviet Union in 1973 for the Mil Mi-24 attack gunship and low-capacity troop transporter, with 1470 rounds, which can also be mounted in GUV-8700 machine-gun pods with 750 rounds. It has a high rate of fire (4–5,000 rounds per minute) and is also one of the few self-powered guns of the Gatling type (i.e. it is gas-operated, rather than requiring an external motor to operate). On the Mi-24 it is mounted in the VSPU-24 undernose turret, with an azimuth of 60° to either side, an elevation of 20°, and a depression of 60°. The gun is slaved to the KPS-53AV undernose sighting system with a reflector sight in the front cockpit. It was replaced by the fixed, side-mounted GSh-30K or the swivel-mounted GSh-23L in the late mark of the Mi-24 helicopters, as it did not provide enough firepower against dug-in or lightly armored targets that did not necessitate a r ...

Gryazev-Shipunov GSh-23
The Gryazev-Shipunov GSh-23 ( rus, ГШ-23) is a twin-barreled 23 mm autocannon developed in the Soviet Union, primarily for military aircraft use. It entered service in 1965, replacing the earlier Nudelman-Rikhter NR-23 and Rikhter R-23. The GSh-23 works on the Gast Gun principle developed by German engineer Karl Gast of the Vorwerk company in 1916. It is a twin-barreled weapon in which the firing action of one barrel operates the mechanism of the other. It provides a much faster rate of fire for lower mechanical wear than a single-barrel weapon. Although it cannot match the sustained rate of fire of an electric Gatling gun like the M61 Vulcan, its initial rate of fire can be higher than that of a rotary cannon like the M61 due to it not needing to spin up to fire. It requires no external power source to operate, but is instead powered by the recoiling of the floating barrels, somewhat like the action of the German MG-42. The Gast principle has been little used in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gryazev-Shipunov GSh-30-1
The Gryazev-Shipunov GSh-30-1 (also known by the GRAU index designation 9A-4071K) is a 30 mm autocannon designed for use on Soviet and later Russian military aircraft, entering service in the early 1980s. Its current manufacturer is the Russian company JSC Izhmash. The name GSH-30-1 is formed from the surnames of the designers Gryazev (Грязев) and Shipunov (Шипунов), the caliber of 30 mm and the single-barrel design of the gun itself. Description The GSh-30-1 is a single-barreled, recoil operated autocannon weighing 46 kg (101 lb). Unlike many postwar cannons, it uses a short recoil action instead of a revolver cannon or Gatling gun mechanism. This results in a reduced rate of fire, but lower weight and bulk. The GSh-30-1 has a rate of fire of 1,800 rounds per minute, customarily limited to 1,500 rounds per minute to reduce barrel wear. Despite that, its barrel life is quite short: 2,000 rounds, with a continuous burst rated for 150 rounds. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GAU-8 Avenger The General Electric GAU-8/A Avenger is a 30 mm hydraulically driven seven-barrel Gatling-style autocannon that is primarily mounted in the United States Air Force's Fairchild Republic A-10 Thunderbolt II. Designed to destroy a wide variety of ground targets, the Avenger delivers very powerful rounds at a high rate of fire. The GAU-8/A is also used in the Goalkeeper CIWS ship weapon system, which provides defense against short-range threats such as highly maneuverable missiles, aircraft, and fast maneuvering surface vessels. The GAU-8/A is currently produced by General Dynamics. History The GAU-8 was created as a parallel program with the ''A-X'' (or Attack Experimental) competition that produced the A-10. The specification for the cannon was laid out in 1970, with General Electric and Philco-Fo |
