Embodiment Construction
[0047] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0048] The application background of the present invention is the low-space orbit in the altitude range of 180-250km. Within the orbit range, for small aircraft (0.3-5m), the main flow state of the atmosphere is the free molecular flow state, and the main components of the atmosphere that can be ingested Contains thin atmospheric particles such as oxygen atoms and nitrogen molecules.

Abstract
The invention relates to a low space orbit rarefied atmospheric molecule intake device, which belongs to the field of air-breathing electric propulsion. The device consists of a suction pipe, a tapered cavity, a long straight pipe, a molecular pump, a power supply, a signal receiver, a signal processor, a signal generator, a pressure gauge a, a storage tank liner, a storage tank shell, an air tank, an air bag, an air bag The installation flange, airbag pump, airbag pump installation flange, pressure gauge b, storage tank valve, pressure gauge c, the above components constitute three parts: air intake device, compression device, and gas storage device, which can realize low space The capture and storage of orbital rarefied atmospheric molecules has both high gas collection efficiency and compression ratio, so as to provide sufficient atmospheric working fluid for the air-breathing electric thruster. The airbag has the functions of storing energy, compensating The shock pulsation pressure of the working fluid, the elimination of harmful vibrations, and the maintenance of a relatively stable pressure environment in the storage tank have functions. The whole device has the advantages of simple structure, high integration, and easy installation.
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...
