二次发射技术在炮射导弹中的应用

here are some merits to launch with guns. But there are higher demands for launch condition. Because of engines and control units, missiles can not endure too high launch acceleration and high pressure gas. So missiles are launched using the two-stage propulsion technology. In this dissertation I make a research on the technology through simulating the process of the two-stage propulsion on the 76mm gun. I introduce the principles of the propulsion technology, the process of the propulsion technology and the charge loading condition. I set up a zero-dimensional interior ballistic mathematical model, process numerical simulation, choose ballistic parameter and protract curve of v-t, v-l, p-t, p-l.
