Throwing cable type space flexible electromagnetic docking mechanism

Abstract

The invention provides a throwing cable type space flexible electromagnetic docking mechanism which is divided into three parts, a driving mechanism and a control system are mounted on a tracking spacecraft, and a driven mechanism is mounted on a target spacecraft. A throwing cable mechanism, an electromagnetic coil and a mechanical claw locking mechanism are mounted in the driving mechanism. The throwing cable mechanism throws out a guide ball so that the guide ball can be captured by the driven mechanism and a throwing cable is recovered to complete butt joint. Electromagnetic force generated by the electromagnetic coil serves as power for launching a throwing cable and buffering power before contact with spacecrafts. A mechanical claw locking mechanism is used for limiting the guide ball in the non-butt-joint period and used for locking the two spacecrafts after butt joint is completed. The control system comprises a laser distance measuring sensor, an attitude sensor, a magnetic torquer and a flywheel. The distance measuring sensor provides relative position information between the two spacecrafts so as to determine whether an active spacecraft and a passive spacecraft meet the butt joint distance requirement or not. The attitude sensor is used for judging the relative attitude of the two spacecrafts and ensuring that the guide ball can be captured. The driven mechanism is provided with the electromagnetic coil for adsorbing the guide ball.

Description

technical field [0001] The invention relates to a spacecraft docking mechanism, in particular to a space electromagnetic docking mechanism capable of realizing locking / unlocking. It is suitable for the short-distance electromagnetic docking between the tracking spacecraft and the target spacecraft after attitude adjustment. Background technique [0002] Traditional spacecraft docking is realized by thrusters, which have many shortcomings such as propellant consumption, plume pollution, and residual heat of combustion products interfering with optical measurement, making the docking efficiency low. Space electromagnetic docking is installed on two adjacent spacecraft. The electromagnetic coil on the ground generates gravitational force to achieve docking, and uses electromagnetic force and electromagnetic moment to realize the shortening of the relative distance and attitude adjustment on the space orbit. Space electromagnetic docking technology is a flexible docking technol...
