A dynamic model and a simulation model of the main components of a propulsion system are established according to the dynamic characteristics of the lunar lander uplift propulsion system, such as the response of on / off switch and the change of main parameters. The working process of a typical lunar lander uplift propulsion system simulation Research. The simulation results show that the simulation results of the engine working process are in line with the expected trends, and the feasibility of using the AMESim software to simulate the performance of the propulsion system is preliminarily verified.
