Air-controlled auxiliary docking device and air-controlled auxiliary docking method for satellites

Abstract

The invention discloses a pneumatic auxiliary docking device and a pneumatic auxiliary docking method for a satellite. The pneumatic auxiliary docking device for the satellite comprises an inflatabledocking lock head, a gasbag structure and an installation base, wherein the inflatable docking lock head is used for conducting flexible guide and conducting docking locking through inflation expansion in the satellite docking process, the gasbag structure is used for inflating in different directions to adjust attitudes, and the installation base is used for being in mechanical connection with asatellite body. The inflatable docking lock head is connected to the first end of the gasbag structure in a sealing mode, and the installation base is connected to the second end of the gasbag structure in a sealing mode. Through the pneumatic auxiliary docking device, the inflation pressure and amount of different areas in the gasbag structure loaded on the service satellite are controlled, so that the variation of the appearance attitude of the gasbag structure is controlled, the inflatable docking lock head is driven to move and is inserted into an engine jet pipe of the target satellite toachieve flexible capturing, and allowance capacity of docking capture positions and angles is high.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an air-controlled auxiliary docking device. In addition, the present invention also relates to an air-controlled auxiliary docking method of a satellite using the above-mentioned air-controlled auxiliary docking device. Background technique [0002] On-orbit service of spacecraft involves on-orbit fuel filling and life extension, maintenance assembly and upgrade, debris removal, auxiliary orbit change, etc., and one of the key technologies is to realize autonomous docking and capture of spacecraft through auxiliary docking devices. [0003] There are many types of existing auxiliary docking devices. The telescopic rod-type auxiliary docking device sends the expandable mechanism into the engine nozzle of the target satellite by extending the double rods, and then shortens the double rods to make the service satellite gradually approach the target satellite. The mechanism captu...
