Space rope net capturing system based on recombining rope system formation flying

Abstract

The invention discloses a space rope net capturing system based on recombining rope system formation flying. The space rope net capturing system comprises a recombining mechanism, a flexible plane rope net and closing-in ropes. The recombining mechanism is composed of four sub-mechanisms the same in structure. Each sub-mechanism comprises a launching-butt joint part and a tied rope control part. After one end of the corresponding closing-in rope enters a shell from a conical barrel center hole outside a shell and sequentially passes through a tension pretensioner, a rope length measuring wheel, a tension measuring wheel and an auxiliary guide wheel of each tied rope control part, the closing-in rope is fixed to the inner wall position of a rope rolling barrel, and the other end of the closing-in rope is connected with the middle portion of a conical rod of the adjacent sub-mechanism. Rope rings are evenly distributed on the periphery of the flexible plane rope net, the closing-in ropes of the four sub-mechanisms are sleeved with the rope rings in a clearance manner correspondingly, and folding and unfolding of the flexible plane rope net are achieved through collecting and releasing of the closing-in ropes. The space rope net capturing system has the beneficial effects that the fault tolerance is good, the operating distance is long and the capturing efficiency is high; and rope net unfolding and folding are conducted through recombining rope system formation flying, rope net capturing reliability can be improved, and control complexity is reduced.

Description

technical field [0001] The invention relates to a space rope net capture system, in particular to a space rope net capture system based on recombinable rope formation flight. Background technique [0002] In order to meet the needs of non-cooperative target acquisition tasks such as malfunctioning spacecraft and space debris in the future, the concept of flexible acquisition has gradually entered people's field of vision, and has become one of the research hotspots in recent years. The concept of flexible capture is a new capture method proposed in recent years. It covers and wraps the target with flexible structures such as nets or cloth, and forms a reliable connection with the mission spacecraft through flexible connectors (such as ropes). The traditional rope net capture system is mostly based on the structure of "task platform + connecting tether + rope net + passive mass block". The traction mass block is launched through the task platform and then pulled to expand t...

Problems solved by technology

[0003] Taking the space rope net capture robot as the application background, aiming at the problems of high launch requirements, short capture distance and poor maneuverability of the traditional rope net capture system, the purpose of the present invention is to provide a space rope net based on reorganizable tether formation flight The capture system adopts four sub-mechanisms with combined functions of ejection separation and docking, combined with the closing rope for space formation flight, and realizes the expansion, maintenance and shrinkage of the rope net through the change of formation configuration and the control of tether retraction and release. operate
