Abstract

The invention discloses a self-cooling microwave-enhanced electric thruster, which belongs to the technical field of aerospace electric propulsion. The self-cooling microwave-enhanced electric thruster includes a metal antenna, a discharge cavity, an air inlet interface, an SMA radio frequency input interface, a tapered outlet, and a permanent magnet ring group. The metal antenna, the discharge cavity and the conical outlet are connected in turn by threads; the permanent magnet ring group is installed outside the discharge cavity and the conical outlet; the air inlet interface and the SMA radio frequency input interface are installed in the threaded through hole of the discharge cavity; this The invention solves the problem of unstable discharge caused by local overheating of the metal antenna caused by long-term discharge in the existing microwave thrusters, and greatly reduces the heat generation of the antenna through the effect of "air cooling", thereby maintaining the stability of the discharge and realizing the thrust The device is self-cooling. Through the conical outlet at the rear of the thruster, the electromagnetic field is locally enhanced, the energy conversion efficiency of the plasma is improved, and the performance of the thruster is improved.

Description

technical field [0001] The invention belongs to the technical field of aerospace electric propulsion, in particular to a self-cooling microwave enhanced electric thruster. Background technique [0002] The desire to explore space and gain knowledge beyond Earth has long been the driving force behind the development of aerospace technology. Electric propulsion is a new type of propulsion technology for spacecraft, which converts electrical energy into kinetic energy of propellant to generate thrust. Compared with chemical propulsion technology, electric propulsion is not limited by the chemical energy of the propellant, and mainly relies on electrical energy (from solar cells or nuclear reactor power supply) to provide energy, which is free from the limitation of chemical energy. [0003] Electron cyclotron resonance (ECR) is a relatively common microwave plasma acquisition method. Since electrons move around the magnetic field lines in a magnetic field, the cyclotron frequ...
