介绍并比较了几种导弹弹射动力系统的特点,在一定假设的基础上对几种弹射动力系统进行了内弹道模型的设计、编制程序并针对某型导弹及内弹道指标进行计算,计算结果显示了在不同弹射动力下,发射筒内工质气体状态参数随时间变化的规律和导弹在发射筒内运动加速度、速度、位移随时间变化的规律.通过比较分析所得的内弹道性能曲线,得出燃气-蒸汽式弹射动力系统所需工质流量小,结构简单,压力及加速度变化平稳,温度适中,导弹速度及位移增加快,发射时间短,内弹道参数较理想,具有很大的优势和发展前景.为导弹弹射动力系统的设计和方案选择提供参考依据.
The characteristics of several missile ejection systems are introduced and compared. Based on certain assumptions, several kinds of ejection systems are designed and designed for the internal ballistic system, and the program is compiled and calculated for some missiles and internal ballistic indexes. The calculation results show Under different ejection forces, the law of the parameters of the working gas in the launcher tube changing with time and the laws of the acceleration, velocity and displacement of the missile moving in the launcher tube with time vary.By comparing the obtained internal ballistics curve, Gas-steam ejection power system requires small working fluid flow, simple structure, stable pressure and acceleration changes, moderate temperature, missile speed and displacement increase faster, shorter launch time, the ideal internal ballistics parameters, with great advantages and development Prospects for the missile ejection system design and program options provide a reference.
