| Abstract: | In a liquid rocket propellant feed system,tank pressure is an important parameter which should be strictly ensured.The pressurization system becomes one of the key systems influencing the reliability target,therefore numerical simulation and ground test are needed in order to optimize its design.The pressurizing process of certain propellant feed system is simulated by AMESim.The result of the simulation has a good agreement with the test,and indicates the validity of the buffer.Besides above,the pressurizi... |
