Abstract:
The turbopump-fed liquid propellant rocket engine is the first staged combustion cycle engine with forced start-up system in China. A forced start-up simulation model was build, cool-flow system testing was performed, and the start-up parameters and procedure were determined in combination with the characteristics of the engine. The problems appearing in the start-up testing, such as overshoot, deflagration, ignition shock in thrust chamber and injector deformation were solved. The results obtained in the research were validated in engine tests.
