An optimum design model of ejection device with blank cartridge is established based on the theories of interior ballistics, gas dynamics and optimization. Aiming at a certain kind of ejection device, a compound simplex method is used to optimize several parameters influencing ejection process of the suspender (e.g. missile or bomb). It is shown by calculation that the maximum acceleration of the suspender can be obviously decreased by the parameters gotten by optimization. Therefore, the optimization model provides a helpful tool to improve the gas dynamics characteristics of ejection devices used in practice now.
