姿控动力系统动态特性仿真及试验
Simulation and experiment of attitude control propulsion system's dynamic characteristics
摘要
Abstract
This study develops a dynamic characteristic simulation model of the Attitude Control Propulsion System(ACPS)based on AMESim software,aiming to investigate the hydraulic pressure characteristics of the ACPS and the effects of water hammer pressure pulsations on engine performance parameters.The ground test sequence of the pro-pulsion system is implemented in the simulation model,and the comparative analysis between simulation results and experimental test data demonstrates that this model exhibits satisfactory predictive accuracy.The research findings re-veal that water hammer pressure waves generated during ignition/shutdown processes of bipropellant liquid rocket en-gine,particularly during high-thrust engine shutdown,can significantly disrupt the normal operation of other subsys-tems within short durations.Notably,the oxidizer pipelines exhibit significantly higher water hammer pressure peaks compared to the fuel pipelines.The potential hazards induced by water hammer effects can be effectively mitigated by implementing measures such as shortening the length of the propellant feed line and increasing the pipeline diameter.关键词
