为了验证超临界氦加温增压技术在运载火箭上应用的可行性,建立了超临界氦加温增压系统试验平台,开展了增压系统试验。通过分析试验过程中超临界氦贮罐压力和温度、增压孔板入口压力、模拟贮箱内压力等参数的变化规律,获得了超临界氦加温增压系统的增压性能。试验中超临界氦加温增压系统工作压力较小,并且系统中的电磁阀与孔板组合能将贮箱压力维持在设计范围内,表明该系统增压性能稳定,是一种安全可靠的液体火箭增压系统。
In order to verify the feasibility of using supercritical helium heating and pressurizing technology on launch vehicles, a supercritical helium heating and pressurizing system test platform was established and a supercharged system test was carried out. The supercharging performance of the supercritical helium heating and pressurizing system was obtained by analyzing the changing rules of pressure and temperature of the supercritical helium storage tank, inlet pressure of the pressurized orifice and simulating the pressure inside the storage tank. The working pressure of the supercritical helium heating and pressurizing system is small, and the combination of the solenoid valve and the orifice plate in the system can keep the pressure of the tank within the designed range, indicating that the system has stable pressurization performance and is a safe and reliable liquid Rocket booster system.
