All of you would have heard about the AK-47 but do you think you know everything about it??
AK stands for Automatic Kalshnikov rifle ,it was invented in the year 1947 by Mikhail Kalashnikov ,a Russian. Design work on the AK-47 began in the last year of World War II (1945). After the war in 1946, the AK-46 was presented for official military trials
Firing the 7.62x39mm cartridge, the AK-47 produces significant wounding (including hydrostatic shock) when the projectile tumbles and fragments in tissue;[7] but it produces relatively minor wounds when the projectile exits the body before beginning to yaw.
Operating cycle
The gas-operated mechanism of an AK-47 (Chinese version)To fire, the operator inserts a loaded magazine, moves the selector lever off of safety, pulls back and releases the charging handle, aims, and then pulls the trigger. In this setting, the firearm fires only once (semi-automatic), requiring the trigger to be released and depressed again for the next shot. With the selector in the middle position (full-automatic), the rifle continues to fire, automatically cycling fresh rounds into the chamber, until the magazine is exhausted or pressure is released from the trigger. As each bullet travels through the barrel, a portion of the gases expanding behind it is diverted into the gas tube above the barrel, where it impacts the gas piston. The piston, in turn, is driven backward, pushing the bolt carrier, which causes the bolt to move backwards, ejecting the spent round, and chambering a new round when the recoil spring pushes it back
Ballistics
The standard AK-47 or AKM fires the 7.62x39mm cartridge with a muzzle velocity of 710 metres per second (2,300 ft/s). Muzzle energy is 2,010 joules (1,480 ft·lbf). Projectile weight is normally 7.8 grams (120 gr). The AK-47 and AKM, with the 7.62×39mm cartridge, have a maximum effective range of around 400 metres (1,300 ft).
