Description

technical field [0001] The invention belongs to the field of air-breathing electric propulsion, and in particular relates to a device capable of capturing, storing and providing dilute atmospheric working fluid for a low-space orbit air-breathing electric thruster. Background technique [0002] The air-breathing electric propulsion system has the advantages and technical difficulties that the traditional electric propulsion system does not have: Compared with the traditional electric propulsion system, the air-breathing electric propulsion system has a lower working orbit (less than 250km), low launch cost, and earth observation At the same time, due to the existence of the thin atmosphere in low space orbit, atmospheric resistance and fuel carrying problems make the development of electric propulsion systems face difficulties such as working fluid acquisition and compensation. Therefore, the air-breathing electric propulsion system uses low-space orbit thin atmospheric mole...
