摘　　要：导弹燃气发生器的合理设计对于满足导弹发射内弹道压力、温度、速度及加速度等指标的要求具有重要作用。对某型导弹发射动力系统的燃气发生器进行装药设计,建立了装药设计的关系式,并对燃气发生器的内弹道进行了计算。计算结果表明,所建立的装药设计关系式能够满足燃气发生器内弹道指标要求。还研究了装药增面比对燃气发生器内弹道性能的影响,计算结果表明装药增面比过大会导致燃气发生器头部压力过大,从而不能满足内弹道指标的要求。The reasonable design of gas generator plays an important role to meet the demands of pressure, temperature, velocity and acceleration of launching interior ballistic. Charge design of one mis- sile power system＇ s gas generator is conducted and formula of charge design is established. Interior bal- listic of gas generator is computed as well. Computation results show that established formula of rammer design can meet demands of interior ballistic for gas generator. And the effect of area-added ratio of charge on interior ballistic parameters is studied. Simulation shows that greater area-added ratio of charge leads to greater head pressure of gas generator which don＇ t meet the need of interior ballistic.
