history

feats during World War II .50-caliber machine gun, M2-type to Korea face of rough skin and flesh of the MiG 23 with 37 mm cannon seems Xinyou Deficit

1947, the newly formed U.S. Air Force began to seek a new gun to replace the 12.7 mm machine guns. World War II experience shows that Germany, Japan, Italy, the Axis fighters occupy an tactical advantage in the gun, the U.S. P-51, P-47 equipped with a wide range of white Browning 12.7 mm machine gun range is short, the power is small, and P- 38 20 mm equipment, \In the following the Korean War, F-86 fighters more exposure machine guns lack the power of the defect, MiG-15 was significantly weaker than the large-caliber gun.
U.S. Navy has for small torpedo boats, gunboats developed an electrically driven Gatling Gatling gun, the 19th century Gatling gun that emerged a new form, driven by the power of human-driven change, the basic principle remain unchanged. The high rate of fire guns, but due to time restrictions on materials technology, barrel wear out quickly under the high rate of fire, very short-lived and have not been used. Later, with metallurgical techniques and new materials development, the modern version of the Gatling Gatling gun can finally surfaced.

1950, General Electric began as the U.S. Air Force's \Chad. J. Gatling invented in the 19th century, Gatling Gun. In 1953, pre-production of the \In the first airborne test of the body exposed to the powder can not successfully discharge of waste, spreading the problem, and for a time led to the suspension test. Later in the F-104 gun bay was designed to better solve the problem after the smoke hole.

the most advanced F-22 still retained the gun, the red circle is the gun at the muzzle, in order to reduce the RCS value, usually is off

After the missiles do not want to prejudice the aircraft after, M61 became the standard weapon of American fighter aircraft, more F-22 designed a lightweight \takeoff and landing is not installed M61, it can be plug-gun pod.) As GE's Ordnance Department has been Martin. Marietta acquisition, so the official name of the M61A1 is now Lockheed - Martin M61A1.
structure

Gatling Gatling gun barrel in the firing rate and life on the possession of inherent advantages. While rotating in the barrel, each barrel firing are at different stages. When the barrel to the highest point of rotation, the bore was shot ammunition made, the highest point of the rotated after ejection - loading - the highest point in the next rotation to send Shiyou was shot - so the cycle. Therefore, the rate of fire the whole gun barrel firing rate is the sum of the six, as six 20-mm single-barrel gun and type in the shooting. Since the shooting of six barrel-sharing loop, so the number of times in the same shooting, the \The main disadvantage of the gun (and perhaps should not call it bad) is a high rate of fire, a short time to spend a lot of ammunition, in order to maintain a continuous shooting time, require large capacity ammunition boxes. Single-barrel gun in Russia, the European fighter aircraft, the ammo is less than the U.S. fighters, one different from tactical concept, the second is the different rate of fire gun.

principle of the original Gatling gun shells commonly used for bomb-chain , including some models of the \Although Gatlin after the principle of development after a long period is extremely reliable, but in the \Shells in the high-speed pull chain, the connection is very easy to distort, bend or even break, resulting in gun jams. In addition, the elastic chain, ammunition boxes also take up valuable space, reducing the amount of ammunition. This requires the development of new devices for bombs.
