| Abstract: | Taking the gas pressure-fed liquid rocket engine with high pressure vessel as a study object, the working process of propellant feed system in the engine was analyzed theoretically. An emulator was established with AMESim. With the emulator, the gas pressure in the vessel was computed while the engine was working. The calculated result was compared with the data obtained in the test. The compared results indicate that the trend curve of the calculated result can maintain consistency with the test date. It verified the correctness of the way to establish the emulator. The method can be used to calculate the gas pressure in high pressure vessel. |
