Problems solved by technology

However, due to the increase of the buffer chamber, this will lead to an increase in the outer contour size and weight of the thruster. In addition, because the buffer chamber is often integrated with the discharge channel, the material will be the same as the discharge channel. Due to the ceramics of the discharge channel The ingredients are special, so the cost is also higher

Abstract

The present invention is an integrated anode structure of channel external distributor for low-power Hall thruster, which includes air guide column, fixed column, air intake chamber, single-row hole chamber, double-row hole chamber, and channel chamber; The air column is inserted into the through hole in the air intake chamber, and the air guide column is stably connected with the air intake chamber by electron beam welding; the fixed column is inserted into the through hole in the air intake chamber, and the fixed column is connected to the air intake chamber by electron beam welding. The air inlet chamber is stably connected; the single-row hole chamber is inserted into the air inlet chamber, and the inlet chamber and the single-row hole chamber are stably connected by electron beam welding; the double-row hole chamber is inserted into the single-row hole chamber , using electron beam welding to achieve a stable connection between the single-row hole chamber and the double-row hole chamber; insert the channel chamber into the double-row hole chamber, and use electron beam welding to realize the double-row hole chamber and the channel chamber stable connection.

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, ...
