A combination of net flying claw devices

Abstract

The invention discloses a net claw device assembly which comprises a capture net, wherein a mass block is arranged at a geometric center position of the capture net; the mass block is connected with amooring rope; the mooring rope is used for being connected with a mooring platform on a spacecraft; and multiple net claws are uniformly arranged at the periphery of the capture net. The capture principle of the assembly disclosed by the invention is as follows: by utilizing the inertia of the capture net and the net claws, after the net claw device assembly is launched out, the capture net is rapidly unfolded, and after the capture net collides with a target, the net claws on the capture net make a re-holding motion, and the net claws can be twisted with the rope net so as to capture the target. Furthermore, by utilizing a cloth bag principle, a closing structure is designed by a closing rope. The capture net has a net-type control function, the effective capture distance and effective capture time of the rope net are greatly increased, and the distance between the capture airship and the target is increased, so that the orbital maneuverability of the capture airship is reduced. According to the net claw device assembly disclosed by the invention, accurate, reliable and high-efficiency on-orbit capture can be realized aiming at a non-cooperative target.

Description

technical field [0001] The invention relates to the technical field of spacecraft capture devices, in particular to a netfly claw device assembly used for on-orbit capture of non-cooperative targets. Background technique [0002] The capture and on-orbit service of spacecraft is a hot spot in the current international space field. How to capture space targets safely, accurately and quickly is a major challenge for the development of space technology in the future. [0003] At present, the autonomous on-orbit capture technology of space robots has been demonstrated and verified by flight tests. However, the captured objects in these flight tests are all cooperative targets, that is, devices equipped with feature marks for measurement and robotic arm grasping or docking. Space debris can be classified as non-cooperative targets. Non-cooperative targets have motion characteristics such as spin, nutation, and escape. It is difficult to obtain real-time measurement feedback for t...

Problems solved by technology

However, space debris can be classified as non-cooperative targets. Non-cooperative targets have motion characteristics such as spin, nutation, and escape. It is difficult to obtain real-time measurement feedback for their spatial relative position and motion information, so it is difficult to capture

On-orbit capture of non-cooperative targets is still a key technical bottleneck that has not yet been resolved in aerospace engineering
