Description
technical field [0001] The invention relates to a supercharging system and a supercharging method applied to a valve helium characteristic test in a satellite attitude control engine medium supply system. Background technique [0002] Satellite attitude control engines generally use cold air as power. In order to increase the specific impulse, helium is generally used as the medium. However, compared with compressed air and nitrogen, the molecular weight of helium is very small, and it is more stringent on the operating characteristics and sealing of the valve. Therefore, a helium characteristic test must be carried out to verify the performance of the valve. [0003] As helium is widely used in the test fields of gas characteristics and sealing of spacecraft components, the requirements for test indicators are gradually increasing, and the test pressure has been increased to 45MPa at present. Since the helium used is bottled helium with a specification of 14MPa / 40L, a boos...
