Embodiment Construction

[0017] A Hall electric propulsion system for satellites in GEO orbit. Under the condition that the carrying capacity remains unchanged, the saved weight resources can be used to increase the weight of the payload and increase the income generated by a single launch mission. It is mainly composed of batteries, power supplies Converter, power processing unit, xenon gas storage and supply module, flow regulation module, Hall thruster, electric propulsion manager, of which:

[0018] The storage battery and power converter are used to provide primary power for the power processing unit; the power processing unit converts the primary power into a secondary power supply and supplies power to the Hall thruster, and suppresses the plasma discharge oscillation and electromagnetic interference generated by the Hall thruster; The xenon gas storage and supply module provides stable pressure xenon for the flow regulation module; the flow regulation module provides xenon gas with a correspond...

Abstract

The invention discloses a Hall electric propulsion system for a GEO orbit satellite. The Hall electric propulsion system comprises a storage battery, a power converter, a power processing unit, a xenon storage and supply module, a flow adjusting module, a Hall thruster and an electric propulsion manager, and under the condition that the carrying launching capacity is not changed, saved weight resources can be used for increasing the effective load weight, the earnings generated by a single launching task are improved, and the problem that a large amount of propellant is needed when a conventional engine is used for carrying out a south-north position protection task of the GEO orbit satellite is solved.

Description

technical field [0001] The invention relates to a Hall electric propulsion system for GEO orbit satellites, belonging to the field of GEO orbit satellite carrying and launch design. Background technique [0002] Satellites in GEO orbit are limited by their carrying and launching capabilities, and the weight and resources of the load directly determine the benefits of the satellites. Traditional chemical propulsion has a low specific impulse (285s), and chemical propellants occupy a large amount of weight resources and space resources of the satellite platform. If a Hall electric propulsion system with a high specific impulse (not less than 1600s) is used for orbital maneuvering, it will save More valuable weight resources. [0003] Taking the north-south position protection task of a GEO orbit satellite as an example, for a 3t high-orbit satellite, the on-orbit life is calculated as 8 years. If a conventional 10N engine is used for the north-south position protection task (...
