Abstract Abstract. In order to investigate the dynamic characteristic of the spacecraft propulsion system, numerical simulation was carried out based on the modular and extensible simulation model UPSSim. The model accurately predicts the global behavior of the spacecraft propulsion system in the priming and shutdown process, and also correctly describes the transient behavior of the subsystems. Due to the distributaries of the attitude control thruster supply pipelines, the propellant flow fluctuation attenuates rapidly in the priming process and the waterhammer peak pressure of main engine supply pipelines decreases significantly. The waterhammer waves of the main supply pipelines propagate to the attitude control thruster supply pipelines and dissipate gradually. The farther from the main engine, the later the pressure fluctuates.
