几种导弹弹射动力系统内弹道性能比较

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.

Comparative studies of interior ballistic performance among several missile eject power systems

Characteristics of several missile eject power systems were introduced and compared.The interior ballistic models of these power systems were designed on the basis of assumed conditions.And the programs were work out to predict and compare the interior ballistic performance about a certain missile and targets.The results of different power systems show the state parameters rules of working fluid with respect to the time in launching canister and the missile acceleration,velocity and displacement changing ru...
