Research of a new method of stage separation

A new method of stage separation with solid gas generators was studied in this paper.First,an overall scheme of separation was presented.Then the model of transient pressure of interstage gas and motion of the two stages was studied.A CFD software was employed to simulate the process of the charging with gas generator in the staging sector.Additionally,the design of solid gas generator and the principles of gas generator propellant selection were given briefly.Eventually,an evaluation based on a catalog of missile shows that this method of stage separating is feasible.
