A software arm capture system and a space non-cooperative target derotation method

Abstract

A software arm capture system, comprising an aircraft platform (1), several software arms (2), a fluid pressure control system, a target detection device, and a capture system controller; several software arms (2) are installed on the aircraft platform (1) On the inside of each soft arm (2) there are several fluid channels evenly distributed in the circumferential direction, and each fluid channel extends axially along the soft arm (2); the fluid pressure control system controls the fluid pressure entering the fluid cavity , to realize the straightening of the soft arm (2) or bending toward the geometric center of the aircraft; the target detection device is installed on the aircraft platform (1), detects the position of non-cooperative targets, and sends the detected position information to the capture system controller The capture controller controls the fluid pressure control system to input fluids of different pressures into the fluid cavity of the soft arm (2), so as to realize the capture of non-cooperative targets.

Description

technical field [0001] The invention relates to a method for derotation of spatially non-cooperative targets. Background technique [0002] A large number of space debris such as the last stage of rockets, invalid satellites, spacecraft mission discards, spacecraft disintegration and collision derivatives in space have posed a huge threat to the development of human spaceflight. The active removal technology of space debris is a research hotspot in the field of spaceflight. The capture of floating debris at close range is the key technical point of the current space debris removal mission. Large-mass, large-diameter space debris flies freely in space, and most of them spin at a certain speed. The spin of space debris is difficult to capture. There is a risk of collision in the direct capture of rolling non-cooperative targets, and it is more appropriate to take the method of derotation and then capture in order to reduce the risk factor. It needs to be racemized by some p...

AI Technical Summary

Problems solved by technology

The rigid mechanical arm will inevitably produce a large instantaneous impact force during the contact derotation process, which will easily lead to damage to the mechanical arm and loss of control of the capture mechanism; the derotation method of the flying net and flying claws will easily cause disordered winding during the derotation process ; Deceleration brush derotation, mechanical pulse derotation and tethered robot derotation and other methods require high-precision control methods and complex mechanical structures to ensure the effective implementation of the scheme
