100 mm anti-aircraft gun S-106A
The 100-mm anti-aircraft S-106A was a Soviet anti-aircraft gun of caliber mm 100th The Soviet designation is 100-мм автоматическая зенитная пушка С-106А and means 100-mm automatic anti-aircraft gun S-106A . In Russian, weapons in which several shots can be fired by actuating the shot release device once, regardless of their caliber, are referred to as automatic weapons. The factory index of the weapon is S-106A, where S stands for the manufacturer's factory and the number 106 for the serial number of the development in this factory. The development of the weapon was discontinued, serial production or acceptance into the armament of the Soviet Army did not take place.
development
In 1955, the Scientific Research Center 58 (НИИ-58) developed the project of an automatic 100-mm cannon S-106A with the mount S-113 (С-113). The weapon was distinguished by a number of structural features. Since it is practically impossible to hit an air target directly with a heavy anti-aircraft cannon, flak shells detonate in the vicinity of the target, creating a fragment cloud. However, the size of the fragment cloud and the weight and speed of the fragments depend on the weight of the bullet and thus on the caliber. As a consequence, this leads to heavy guns with poor tactical mobility. With calibers over 100 mm, the weight of the grenade and cartridge must be loaded separately, which reduces the rate of fire. An increase in the hit probability can also be achieved by increasing the rate of fire. However, this is problematic due to the high weights of larger calibers. In addition, the load on the pipe increases at high fire speeds.
At least one prototype of the weapon was built. Ultimately, the development of the cannon was stopped, as the tasks of the heavy anti-aircraft artillery were increasingly taken over by anti-aircraft missiles from the mid-1950s.
construction
The barrel of the cannon has a muzzle brake with an efficiency of 40%. The pipe brake worked hydraulically, the pipe fetcher pneumatic-hydraulic. The tube was water cooled.
Grenade cartridges were fired . A magazine was used that was located above the barrel of the weapon. The magazine consisted of three assemblies: the feeder, the conveyor belt and the magazine drum. The feeder was to the right of the barrel, seen in the direction of fire, and took two shell cartridges. While the first cartridge was being inserted into the chamber during the barrel return, the second cartridge took its place. The conveyor belt lay over the barrel and transported the grenade cartridges from the magazine drum on the left to the feeder. The conveyor belt took eight shell cartridges, the magazine drum eleven. The drum and conveyor belt were driven by an electric motor.
Grenades weighing around 15 kg were fired. The muzzle velocity was 1118 m / s. The maximum shot height was over 18,000 m. The automatic enabled a rate of fire of 60 rounds per minute. In the case of grenades with time fuses, the rate of fire fell to 45 rounds per minute, as the duration of the fuse had to be set in the fuse setting machine . The total weight of the weapon is given as 4,500 kg.
