Description

technical field [0001] The invention relates to a vector adjustment mechanism for adjusting the thrust vector direction of a thruster when an electric propulsion system performs tasks such as north-south position protection, east-west position protection, and track transfer, and belongs to the technical field of space application equipment. Background technique [0002] The research on foreign vector adjustment mechanisms has been carried out for many years, and the product types are relatively rich, and have been verified by many flights. The domestic electric thruster thrust vector adjustment mechanism has not been applied in space yet. [0003] The present invention designs a vector adjustment mechanism with the thruster as the bearing object based on the track maintenance (north-south position maintenance, east-west position maintenance, momentum wheel unloading, and final derailment) tasks that are currently the most widely used in domestic electric propulsion technolog...
