对以脉冲方式工作的空间姿控、末修用液体火箭发动机系统的动态特性进行数值仿真分析,并与热试车实验数据进行了比较,还讨论了多推力室动力系统在不同数量、不同类型推力室点火工作时推力响应的特点。
The dynamic characteristics of the liquid rocket engine system are numerically simulated and analyzed in the space attitude control and the final repair with pulse mode. The experimental data are compared with the thermal test data. The effects of the thrust of the multi-thrust chamber on different numbers and types of thrust The characteristics of the thrust response in the ignition work room.
