Embodiment

[0036] figure 1 It is a schematic diagram of the structure of a traditional ion wind thruster. Such as figure 1 As shown, the overall structure of the traditional ion wind thruster includes a discharge device and a measurement device. The discharge device includes an ionization power supply 1, an ionization electrode 2 and a collector electrode 3; the measurement device includes an oscilloscope 4, a current transformer 5 and an anemometer 6. Under the action of a high-voltage power supply in a traditional ion wind thruster, electrons in the discharge space between the ionization electrode 2 and the collector electrode 3 are excited and collide to generate charged particles; the charged particles move toward the collector electrode 3 under the action of an external electric field, and Collisions with neutral gas molecules create an ionic wind effect. However, the traditional ion wind thruster is limited by the principle of corona discharge. There is a limit to the concentrati...

Abstract

The invention discloses an ionic wind thrust device cooperating with microwaves. The device comprises an ion wind thruster and an energy injection device, wherein an electric field generated by the ionic wind thruster ionizes dielectric gas in a discharge space of the ionic wind thruster to generate electrons, and the electrons are combined with neutral gas molecules in the discharge space to formfirst charged particles; the energy injection device is used for injecting energy into a discharge space of the ion wind thruster to increase the energy of the first charged particles, and the firstcharged particles and neutral gas molecules are excited to generate second charged particles; and the first charged particles and the second charged particles drive neutral gas molecules in the discharge space to move to form ionic wind. According to the ionic wind thruster cooperating with the microwaves, the concentration of charged particles is increased through the energy injection device, andthe macroscopic thrust effect of the ionic wind thruster is optimized.
