Abstract:
Aiming at the performance sensitivity of hydrogen peroxide/kerosene staged-combustion engine, the sensitivity analysis method was used to analyze and evaluate the influence of internal and external factors on the engine performance. The performance sensitivity of engine thrust and mixture ratio corresponding to the influence factors was obtained. The results show that pre-burner venturi flow area, turbine nozzle area, turbine efficiency and hydrogen peroxide pump efficiency have great effect on engine thrust; kerosene venturi flow area, hydrogen peroxide main venturi flow area, kerosene and hydroxide pump head have great effect on engine mixture ratio. In the actual engineering project, more attention should be paid to the factors that greatly affect the engine performance.
