Abstract:
Taking the liquid rocket engine of orbit and attitude control system as the study object, an emulator was established with AMESim according to the modular modeling idea. The simulation computation of water hammer pressure in the pipeline while the engine system was working was performed. The results show that the running of orbit control engine is a major factor creating high water hammer. The compared result of theoretical calculation and test data indicate that the simulation models can give reasonable descriptions for generative process of water hammer. The measure to reduce the amount of water hammer is introduced.
