Abstract

The invention relates to a tangential field plasma thruster capable of improving thrust resolution and working medium utilization rate, and belongs to the field of tangential field plasma thruster design. It solves the problems of insufficient thrust resolution, insufficient ionization under low-power working conditions, and low utilization rate of working fluid in the non-drag application of the existing tangential field thruster. The tangential field plasma thruster of the present invention has an axisymmetric structure as a whole, including a main anode, a first gasket, a hollow cover plate, a casing, a first-stage permanent magnet, a second gasket, a second-stage permanent magnet, and a wall anode and ceramic channels. The present invention regulates the motion behavior of electrons inside the channel in real time by adjusting the anode potential of the annular wall inside the ceramic channel, thereby fine-tuning the ionization process and output performance parameters, achieving the purpose of improving the output thrust resolution of the thruster, and at the same time promoting radial migration of electrons, and further Increase the collision probability of electrons and atoms near the wall, realize the radial expansion of the ionization zone, and achieve the purpose of improving the utilization rate of the working medium of the thruster.

Description

Technical field [0001] The present invention relates to a modulatable thrust channel internally ionization process and improving thrust resolution and working utilization rate, which belongs to the field of slice plasma thrust design. Background technique [0002] Will cut the field plasma thruster is an internationally emerging type of electric propulsion concept, which relies on multi-stage permanent magnets that can effectively restrain the cathode release of electronically released electrons, and electrons in the magnetic mirror effect. The internal magnetic tip is reciprocated, so that it can guarantee the effective bondage of electrons, reduce the plasma wall loss and the corrosion of the wall, and ensure ionization, to ensure the normal operation of the thrust. At present, research on this thrust has been found that its output thrust can span three orders of magnitude, with feasibility to achieve high precision rails that have no towed satellite. Since the LISA gravitation...
