A fast calculation model for interior ballistics simulation of a recoilless launch system with high chamber pressure

Abstract Recoilless launch system is economical and convenient. This paper provided a recoilless with high chamber pressure based on the theory of gun. A program for interior ballistics simulation mixed propellent was designed. The curves projectile velocity time travels were by program. And phenomena different combustion stages presented curve are discussed. results reached set indicators, it consistent actual ballistics. designed model has certain reference value real-time fast computation.
