Academic Research Of The Two-Stage Propulsion Technology Of Gun-Launched Missile

The technology of gun-launched missile has been commonly recognized and widely under researched by the scientists domestic and abroad, which has many advantages such as extending firing range, improving hitting accuracy and reducing launch cost. This dissertation focuses on the study of a new launching technology of missile by the gun, in which the high-low launching theory is applied to the two-stage propulsion technology.The process of interior ballistics of the two-stage propulsion technology is designed in this paper. And the chamber configuration design and charging design are investigated in this paper based on the two-stage propulsion technology process of the 76mm gun. The theory of the two-stage propulsion technology, the process of the two-stage launching technology and the device in the gun chamber are discussed, and also the physics model in the chamber is raised in this paper. The zero-dimensional interior ballistic mathematical model is established to analyze the process of the technology. The influences of the charging variety and different charging conditions on the ballistic performance are discussed in detail in this paper. At last, for meeting overload factor request of launching technology of missile by the gun, the loading conditions which satisfy the ballistic requirements are determined. The p ～ t,p～l,v～ t,v～ l,a～ t,a ～ 1 curve of the two-stage propulsion process is calculated.
