Taking the hydrogen-oxygen expansion cycle engine as the research object, based on the idea of modular modeling and simulation, the dynamic model of engine components is given, and the liquid rocket engine system model is constructed based on the working principle of the engine system, and the transient state of the hydrogen-oxygen expansion cycle engine is developed simulation Research. According to the simulation results and combined with the test data, the engine system model is verified and optimized, and the optimized model is simulated and calculated in the whole process of engine dynamics. The simulation results show that the main performance parameters during the dynamic change of the engine are in good agreement with the test data, which verifies the simulation model accuracy and design feasibility.
