摘要
介绍了系统动态仿真技术在我国高压补燃氢氧发动机研制中的应用。简要介绍了用于液体火箭发动机系统动态仿真的数学模型的建立和处理。实践结果表明 ,将系统动态仿真技术应用于火箭发动机的研制中 ,达到了完善发动机系统配置、优化发动机系统构成、指导发动机进行冷态试验和制定发动机的启动、关机时序的目的 。
The application of system dynamic simulation technology to the development of LOX LH 2 staged combustion rocket engine in our country is introduced in this paper. The building and processing of the mathematical model used in the dynamic simulation of liquid rocket engine are briefly described.The practice has shown that the application of system dynamic simulation technology perfects the engine system configuration,optimizes the engine system constitution,and guides the engine cold flow test and the setup of start and cutoff sequences,and it has played an important role in the development of LOX LH 2 staged combustion rocket engine in our country.
