摘　　要：建立了某泵压式液体火箭发动机系统组件数学模型,在此基础上进行了发生器氧化剂汽蚀管堵塞的动态仿真计算。仿真计算结果表明:发动机涡轮转速在堵塞初始快速下降,之后下降变缓。Based on a pump-fed liquid rocket engine system, the mathematical models with main components were established. The dynamic simulation for the jamming of generator oxidizer venturi was carried out according to the models. The results indicate that the engine turbine velocity drops down rapidly at initial period of the venturi jamming and then drops slowly.
