Abstract:
The tank pressurization system is an important constitute of liquid rocket propellant system which controls the pressure and volume flow rate of propellants feeding to the engine. The temperature is a key parameter which determines whether the pressurization system can work naturally or not. In this research, the pressure characteristics of tank pressurization system under different temperatures are analyzed by experimental method. The results show that the pressure characteristic increases with temperature decrease from room temperature to -50 ℃; -35 ℃ is the critical temperature that the system can not work below this threshold value without any improvement measures; some corresponding countermeasures are proposed to deal with the problem occurring when the temperature is below the critical temperature, and available temperature range is expanded to -50 ℃ which satisfy the
