Spacecraft boosting system utilizing space plasmas and magnetic field action

Abstract

The invention discloses a spacecraft boosting system utilizing space plasmas and magnetic field action. A long conducting rod of the spacecraft boosting system extends out of a spacecraft and is connected to the spacecraft by a control system, a space plasma collection device used for collecting electrons and an electron emission device used for emitting the plasmas in the long rod into the space are arranged at two ends of the long conducting rod respectively, a power supply system provides potential difference and working voltage for two ends of each of the space plasma collection device and the electron emission device, the collection device collects the plasmas from the space into the long conducting rod, the plasmas flow to the other end of the long conducting rod under the action of potential difference, and the emission device emits the electrons in the rod into the space to realize continuous generation and acting force of current. Compared with the prior art, the spacecraft boosting system has the great advantages that a working medium does not need to be carried, emission cost is lowered greatly, and in-orbit full-life-cycle working of the spacecraft is realized.

Description

technical field [0001] The invention relates to the technical field of spacecraft propulsion and space environment utilization, in particular to a fuel-free system using space plasma to propel the motion of an on-orbit spacecraft and a propulsion method for using the system to propel the motion of an on-orbit spacecraft. Background technique [0002] The plasma region is a low-density electron layer that exists in space. An electron collector is installed at one end of the conductor to collect electrons from the plasma region, and an electron emitter is installed at the other end to release electrons into the plasma region, which is generated due to its current collection effect in the plasma. Under the action of the earth's magnetic field, the electric current will be affected by the Ampere's force to generate thrust. [0003] Space propulsion technologies can generally be divided into chemical propulsion, electric propulsion, and other propulsion technologies (such as sola...
