Abstract

The invention relates to an ion wind thrust device. In the present invention, a multi-stage ionization enhancement device is added upstream of the ion wind thruster. The multi-stage ionization enhancement device generates a large number of charged particles under the action of the ionization enhancement power supply, and the charged particles enter the ion wind thrust under the action of the flow transport of the gas in the adjacent space. The device improves the charged particle density in the ionization zone of the ion wind thruster, eliminates the ionization zone charged particle density limit of the original ion wind thruster, and overcomes the limitation of the ionization density limit of the traditional ion wind thruster on the performance of the ion wind thruster , and increase the energy transfer with neutral gas molecules, so that more neutral gas molecules can participate in the work of the ion wind thruster, improve the energy conversion efficiency, and further improve the performance of the ion wind thruster.

Description

technical field [0001] The invention relates to the field of electric propulsion near space, in particular to an ion wind thrust device. Background technique [0002] The ion wind thruster has the characteristics of simple structure, high reliability, and no self-carrying propellant, etc., and has a wide range of application values ​​in the field of electric propulsion in adjacent space. The working process of the ion wind thruster includes the ionization process and acceleration process of particles. However, the low density of charged particles in the traditional ion wind thruster limits the improvement of the performance of the ion wind thruster. Improving the ionization intensity of the ion wind thruster has important application value. [0003] Therefore, improving the performance of the ion wind thruster is a technical problem to be solved urgently. Contents of the invention [0004] The purpose of the present invention is to provide a kind of ion wind thruster, ha...
