Abstract

The invention discloses a water cooling structure magnetic plasma thruster. An expanded anode, a hollow cathode and internal conical surface insulating ceramic form a discharge chamber. An insulator is designed to be connected with the cathode and the anode, and insulating connection is achieved. A flexible graphite gasket is installed in the key matching position, and a sealing purpose is achieved. An installation insulating piece is designed to achieve radial matching connection of the thruster and a magnetic coil, the coaxality is ensued, and the precision of the bit-type of an additional magnetic field is improved. The thruster is fastened through a locking column structure, and thus the thruster can be adjusted at random relative to the axial position of the magnetic coil. The cathode and the anode both adopt cavity water cooling structures. Argon servers as a propellant, the cathode and the anode supply air at the same time, discharging is conducted in the discharge chamber through high-voltage breakdown between the cathode and the anode, and plasmas are continuously ionized and are ejected from the anode under the action of the additional electromagnetic field to produce thrust. The water cooling structure magnetic plasma thruster can stably work in the power range of 10-20 kW, provides the bull level thrust, and has an important significance to the structural design and experimental researches of magnetic plasma thrusters.
