Embodiment Construction

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

[0062] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0063] In the present invention, unless otherwise specified, "arranged on", "arranged on" and "arranged on" do not exclude the presence of intermediates between the two. In addition, "arranged on or above" only means the relative positional relationship between two parts, and under certain circumstances, such as after the product direction is reversed, 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 solutions of the present invention, and sho...

Abstract

The invention provides an air suction type electric propulsion system capable of achieving on-track self-repairing. The air suction type electric propulsion system comprises a nanowire array thruster, a gas inlet module and a control module; the nanowire array thruster is configured to execute the following actions of generating thrust through an electric field ionization propellant and growing nanowires by adopting a repairing agent through a thermal oxidation method; the gas inlet module is configured to execute the following actions of collecting gas in a track and providing the collected gas as the propellant and the repairing agent to the nanowire array thruster; and the control module is configured to control the nanowire array thruster to be switched among a plurality of modes, so that the nanowire array thruster generates the thrust in the working mode and grows the nanowires in the repairing mode.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an air-breathing electric propulsion system capable of autonomous repair on orbit. Background technique [0002] Ultra-low-orbit satellites can greatly shorten the imaging distance and improve image resolution, and have great application value in land and resources surveying and 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 de-orbiting, which greatly limits the life of the satellite. Electric propulsion with high specific impulse and light weight is usually used The system performs resistance compensation to maintain the orbital altitude of the satellite. Still, satellite lifetimes are limited by the amo...
