Abstract

The utility model relates to a linear electromagnetic damping device for spacecraft recovery, relating to the field of spacecraft recovery. The purpose of the present invention is to solve the problem that the parachute landing system, which is widely used in the existing spacecraft recovery device, has the disadvantages of large diameter and heavy weight of the umbrella surface, and the problem of occupying the load resources of the spacecraft. When it is ready to be recycled, multiple evenly arranged support frames support the recovery net, and the net angles of the recovery net are respectively connected with the linear electromagnetic damper movers of the multiple support frames. When the spacecraft falls into the recovery net, it will pull the mover of the linear electromagnetic damper to move downward. At this time, the permanent magnet on the stator cuts the No. 3 conductor plate on the mover to generate a magnetic field, which will generate a braking force against falling into the recovery net. The descending speed of the inner spacecraft is buffered to control the descending speed of the spacecraft. After the recovery is completed, the drive coil integrated in the linear electromagnetic damping is used to lift the mover and the recovery net to prepare for the next spacecraft recovery. It is used to recover spacecraft.

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....
