摘要
针对月面着陆器上升级推进系统开关机响应、主要参数变化等动态特性问题,建立了推进系统的主要部件动力学模型与仿真模型,对典型的月面着陆器上升级推进系统工作过程开展了仿真研究。仿真结果表明,发动机工作过程仿真结果符合预期趋势,初步验证了利用AMESim软件进行推进系统性能仿真研究的可行性。
To simulate the lunar lander ascend module propulsion system dynamics, the models of the propulsion major parts were built. A simulation of the lunar lander ascending module propulsion classical operation was conducted. The results showed that the simulation were consistent with the expectation and the tests. The models and methods were verified. It is possible to simulate the pro- pulsion system dynamics using the AMESim software.
