摘要
在建立动态数学模型的基础上，对某型高压补燃循环液体火箭发动机启动过程的动态特性进行了计算机仿真，得到发动机推进剂入口压力变化与阀门开关时序变化对发动机启动特性影响的规律。
This paper focused on the simulation of the start up dynamic characteristics for a liquid propellant staged combustion rocket engine.On the base of the establishment of the start up dynamic model,a simulation code was developed,and the effects of inlet pressure variation and valve timing on the start up dynamic process were simulated
