NS-23An aviation cannon of system Nudelman - Suranov23-mm
VYa 23mm cannon which was taken advantage in 1941, had too strong recoil and was established basically on attack aircraft Il - 2. In 1943 in ОКB-16 the new 23-mm a cartridge has been developed. The initial missile velocity in a trunk in length of 1450 mm made 700 m/s. The new part has been developed also. The weight of such cartridge with a part appeared almost twice less weights of a cartridge with a part of VYa 23mm cannon . Under a new cartridge in ОКB-16 the NS-23 (Nudelman - Suranov) cannon has been created. Ground state tests of NS-23 were completed on May, 4, 1944, and also air tests on Yak-9 on June, 7, 1944 have been finished. Work of NS-23 has been based on use of energy of recoil of a trunk. NS-23 cannon was issued in two variants: NS-23KМ - wing and motor and NS-23С with the synchronous mechanism. The data of NS-23 in wing variant of a gun were the following. Length of a trunk: 1450 mm. Dimensions of a cannon: length of 1985 mm, width of 165 mm, height of 256 mm. Weight of a gun of 37 kg. Rate of shooting of 600 shots/minutes. A guaranteed barrel life of 4000 shots/minutes. |
