Embodiment Construction

[0061] The present invention will be further described below with reference to the accompanying drawings in conjunction with specific embodiments.

[0062] It should be noted that various components in the various figures may be shown exaggerated for illustration purposes and not necessarily to correct scale. In the various figures, identical or functionally identical components are provided with the same reference numerals.

[0063] In the present invention, unless otherwise specified, "arranged on," "arranged over," and "arranged over" do not exclude the case where there is an intermediate between the two. In addition, "arranged on or above" only means the relative positional relationship between two components, and in certain circumstances, such as after reversing the product direction, it can also be converted to "arranged under or below", and vice versa Of course.

[0064] In the present invention, each embodiment is only intended to illustrate the solution of the prese...

Abstract

The present invention provides an in-orbit autonomously repairable air-breathing electric propulsion system, comprising: a nanowire array thruster configured to perform the following actions: generating thrust by ionizing the propellant by an electric field; and thermal oxidation by employing the repairing agent a gas inlet module configured to perform the actions of: collecting gas in the orbit; and providing the collected gas as a propellant and a remediation agent to the nanowire array thruster; and a control module configured to control the nanowires The wire array thruster switches between multiple modes to enable the nanowire array thruster to generate thrust in a working mode and grow nanowires in a repair mode.

Description

technical field [0001] The invention relates to the technical field of aerospace, in particular to an air-breathing electric propulsion system that can be repaired autonomously on-orbit. Background technique [0002] Ultra-low orbit satellites can greatly shorten the imaging distance and improve the image resolution, and have great application value in land and resources mapping, agriculture, forestry, ocean, meteorology, and disaster protection. Reduce satellite costs. [0003] However, there is a thin atmosphere with free molecular flow in the ultra-low orbit environment. The resistance caused by the thin atmosphere will continue to reduce the orbital height of the satellite and cause deorbiting, which greatly limits the life of the satellite. Generally, electric propulsion with high specific impulse and light mass is used. The system performs drag compensation to maintain the satellite orbit altitude. Still, satellite life is limited by the amount of propellant it carri...
