Abstract :
Mathematic equations considering the real-gas to simulate the pressurization system diagram for launch vehicle tanks were established with the Beattie - Bridgeman equation of state (EOS) due to the issue that the gas character cannot be accurately described by ideal-gas equation. The simulated time histories of pressure and temperature results on both gas EOSs during the starting process of a typical pressurization system were obtained. The influence of real-gas effect to the pressure and temperature were discussed. Simulation results show the effectiveness of the proposed method.
