Abstract

The invention relates to an electric propelling engine gas distributor, relates to the problem that whether propellant gas distribution of an electric propelling engine is uniform or not and belongs to the field of electric propelling. Due to non-uniform distribution of gas inlet pipelines, traditional gas distributors cause non-uniform circumferential distribution of propellant gas in electric discharging channels, and consequently, electric discharging of thrusters is affected. In order to solve the problem, the gas distributor with circumferential and radial gas transmission grooves and non-uniform distributed axial gas transmission holes/grooves is designed. The gas distributor mainly comprises a distributor-upper bottom, a distributor-lower bottom, gas inlet pipes and fastening screws. By forming gas transmission grooves, circumferential and radial diffusion of the propellant gas are manually inhibited, and non-uniform axial gas transmission holes/grooves are formed according to the different propellant gas densities in the different positions, so that the propellant gas enters the electric discharging channels more uniformly and the uniform and stable neutral particle environment is provided for the thrusters.

Description

Technical field: [0001] The invention belongs to the technical field of electric propulsion, and relates to a gas distributor for an electric propulsion engine. Background technique: [0002] As an advanced space propulsion technology, electric propulsion technology has a wide range of applications in spacecraft attitude control, orbit transfer, north-south position maintenance, and repositioning. With the gradual development of micro-satellites, electric thrusters are also developing in the direction of low power. Low-power electric thrusters have unique advantages in formation flight and position maintenance of micro-satellites. [0003] With the low power of the electric thruster, the volume of the discharge channel of the thruster is greatly reduced, and the design difficulty of the gas distributor increases. Due to the uneven distribution of the intake pipeline, the gas distributor of the traditional multi-hole gas transmission type electric thruster will cause the cir...
