Abstract

The invention discloses an air-breathing electric rocket for a low-orbit spacecraft, which belongs to the field of space technology and vacuum technology. The electric rocket comprises a porous array plate, a turbo molecular pump, a compressed gas conveying pipeline, an electric thruster and a spacecraft body, wherein the turbo molecular pump is arranged on the front end of the spacecraft body; the electric thruster is arranged on the rear end of the spacecraft; one end of the compressed gas conveying pipeline is connected with the turbo molecular pump; the other end of the compressed gas conveying pipeline is connected with the electric thruster; the porous array plate is fixedly connected to a front end of the turbo molecular pump. The electric rocket can collect dilute gas of a spacecraft orbit environment as working medium of the electric thruster, the rigidity limitation on the service life of the spacecraft caused by the using up of fuel can be completely avoided, and the quantity of effective loads carried by the spacecraft and the capability of completing more complex tasks of the spacecraft are improved.

Description

technical field [0001] The invention relates to an air-breathing electric rocket used for low-orbit spacecraft, belonging to the fields of aerospace technology and vacuum technology. Background technique [0002] The traditional electric propulsion technology uses electric energy to ionize the propellant and accelerate the ejection to generate thrust. Its specific impulse is as high as 3000 seconds, which is more than an order of magnitude higher than that of chemical rockets. It is the current advanced space propulsion technology and can be used for spacecraft orbit maintenance. , attitude control, maneuvering orbit change and deep space exploration and other tasks. However, the electric thruster still needs to carry working fluid from the ground, and its service life is limited by the amount of working fluid carried. In recent years, the new concept of using captured rarefied gas in the orbital environment of spacecraft as the working medium for electric propulsion has re...
