| Abstract: | Based on a pump-fed liquid rocket engine system, the mathematical models with main components were established. The dynamic simulation for the jamming of generator oxidizer venturi was carried out according to the models. The results indicate that the engine turbine velocity drops down rapidly at initial period of the venturi jamming and then drops slowly. |
