Abstract

The invention provides a spacecraft recycling linear electromagnetic damping device, relates to the field of spacecraft recycling, and aims at solving disadvantages of parachute landing systems that are conventionally used as spacecraft recycling devices, like large diameter and large weight of the parachute surface, and occupying spacecraft load resources. When preparing recycling, a plurality ofevenly arranged support frames support recycling nets, and net corners of the recycling nets are respectively connected with linear electromagnetic damper movers of the support frames. When the spacecraft falls into the recycling nets, the linear electromagnetic damper movers are pulled downward; meanwhile, permanent magnets on stators cut third conductor plates on the movers to generate magneticfields; and braking forces are generated to buffer the descent process of the spacecraft falling into the recycling nets and control the falling speed of the spacecraft. After the recycling process is completed, the movers and the recycling nets are lifted by drive coils integrated in the linear electromagnetic dampers to prepare for a next spacecraft recycling. The device is used for recycling aspacecraft.

Description

technical field [0001] The invention relates to a rectilinear electromagnetic damping device for spacecraft recovery, belonging to the field of spacecraft recovery. Background technique [0002] Spacecraft recovery technology is a technology for a spacecraft to break away from its original orbit and enter the earth's atmosphere and land safely on the ground. Recovering a spacecraft belongs to the final phase of the spacecraft return process, the landing phase. After the spacecraft is decelerated by a special deceleration device, it is called a soft landing at a certain speed. Without special deceleration, it is called a hard landing. The recovery device is an important means to achieve a soft landing. The reliable performance of the spacecraft recovery device It plays an important role in the safe landing of spacecraft. [0003] The recovery of the spacecraft can choose land landing or sea splashing, and there are land recovery systems and sea recovery systems accordingly....
