Abstract

The invention relates to a thermal pressurized xenon filling method of an electric satellite propelling system, belongs to the technical field of high-purity xenon filing experiments in the electric satellite propelling system and is suitable for the filling experiments of electric propelling systems using high-purity xenon as a work medium. According to the technical requirement of high-purity xenon filing in the electric satellite propelling system, a thermal pressurizing type xenon filling method is reasonably designed. The method has the advantage of being high in cleanliness degree, accurate in temperature control, high in reliability, convenient in module replacement and comprehensive in date measurement and the filling task requirement of the high-purity xenon can be effectively met. According to the method, a pneumatic valve is used for automatic control and has the strong matching performance with the system pressure and temperature; the cooperation of the switch control on the pneumatic valve and the filling process is realized; the automatic control on xenon suction and filling can be realized; the xenon in a satellite gas supply bottle can be prevented from flowing back to an experiment system during an experiment and the safety and the reliability of the xenon filling experiment can be guaranteed.

Description

technical field [0001] The invention relates to a hot-pressurized xenon filling method for a satellite electric propulsion system, belongs to the technical field of high-purity xenon filling tests for satellite electric propulsion systems, and is suitable for filling tests of all electric propulsion systems using high-purity xenon as a working medium. Background technique [0002] At present, there are many types of propulsion systems for in-orbit flight, among which the electric propulsion system has developed rapidly in recent years due to its high specific impulse, especially the Hall electric propulsion system and the ion electric propulsion system are popular, and are often used in geostationary orbit satellites The platform performs tasks such as north-south position keeping, attitude control (momentum wheel unloading), orbit control, and even synchronous orbit transfer. In addition, electric propulsion systems can accomplish tasks that conventional propulsion systems ...
