Abstract:
For the turbopump in liquid rocket engine, a simulation program was compiled to analyze its start-up process based on the theoretical analysis.Moreover, an experimental rig for the start-up performance of turbopump was built and the turbopump in a certain type of engine was tested for verification.The simulation results show that the model meets the study requirements of the start-up process.The experimental results show that the experimental scheme is suitable for the performance study of turbopump start-up, and can be used in the investigation of turbine, pump, mechanical seal, bearing and other important components.
