基于AMESim平台的氢氧火箭发动机启动过程仿真研究

摘要

Accorded to the modular modeling method,a dynamic simulation module library is developed by using AMESet,which is an advanced developing tool of AMESim.The simulation system for the start-up process of LOX/LH2 rocket engine is developed and used in a rocket engine.The simulation result matched with the experiment result very well,thus validated the accuracy of the simulation model.%根据模块化建模仿真的思想,采用AMESim软件中的二次开发平台AMESet开发了氢氧火箭发动机动态仿真模型库,建立了氢氧火箭发动机启动过程动态仿真模型.使用该模型对某型氢氧火箭发动机进行启动仿真,仿真结果表明:仿真结果与实际试车数据符合得很好,验证了该模型的准确性.
