Abstract

The invention discloses a channel external type distributor anode integrated structure for a low-power hall thruster. The channel external type distributor anode integrated structure comprises a gas guide column, a fixing column, a gas inlet chamber, a single-row hole chamber, a double-row hole chamber and a channel chamber. The gas guide column is inserted into a through hole in the gas inlet chamber, and the gas guide column is stably connected with the gas inlet chamber in an electron beam welding mode. The fixing column is inserted into a through hole in the gas inlet chamber, and the fixing column is stably connected with the gas inlet chamber in an electron beam welding mode. The single-row hole chamber is inserted into the gas inlet cavity, and the stable connection between the gasinlet cavity and the single-row hole chamber is achieved in an electron beam welding mode. The double-row hole chamber is inserted into the single-row hole chamber, and the stable connection between the single-row hole chamber and the double-row hole chamber is achieved in an electron beam welding mode. The channel chamber is inserted into the double-row hole chamber, and the stable connection between the double-row hole chamber and the channel chamber is achieved in an electron beam welding mode.

Description

technical field [0001] The invention relates to a radial gas outlet distributor structure, which is suitable for Hall thrusters and belongs to the technical field of gas homogenization measures for Hall thrusters. Background technique [0002] Hall propulsion technology is the mainstream technical direction of spacecraft electric propulsion at present. The Hall thruster mainly includes hollow cathodes, discharge chambers, magnetic poles, magnetic coils, anode / gas distributors, propellant delivery pipelines and support structures; Seoul propulsion technology can increase the payload of spacecraft, reduce launch costs, and extend service life. It is an effective means to improve the efficiency and competitiveness of commercial satellites in the future. [0003] Hall thruster consists of hollow cathode, discharge chamber, magnetic pole (composed of front and rear magnetic pole plates, inner and outer magnetic cores, inner and outer magnetic screens, etc.), inner magnetic coil, ...
