Abstract:
Aiming at the large driving resistance and low firing frequency problems of traditional internal energy Gatling guns,a new type of internal energy rotating piston drive technology is developed for a 3 pipes Gatling gun according to working characteristics of air-guided automatic weapons and the structural characteristics of Gatling guns. A drive scheme using a rotating piston for a self powered revolving gun is proposed based on interior ballistic theory for launching guns and the gas dynamics for automatic weapons. A numerical calculation model for the rotary drive scheme of the piston is established. The technical characteristics of the driving scheme for the piston are obtained by numerical analysis considering the boundary conditions of the launching Gatling gun. The results show that the rotary piston drive technology can improve the rotation speed of the barrel group by 80% with the low pressure of the air guide chamber for the 3 pipes Gatling gun.
