Flying mesh catapulting device for acquiring discarded spacecraft

Abstract

The invention relates to a flying mesh catapulting device for acquiring a discarded spacecraft and particularly relates to a flying mesh catapulting device for on-track acquisition of a discarded spacecraft and track resetting, belonging to the field of space mechanism designs. The flying mesh catapulting device concretely comprises a flying mesh, a flying mesh catapulting device and a rope release and control mechanism. An initiating explosive device is catapulted in the acquisition device, and the flying mesh can automatically unfold and realize retention of configuration in the process of flying towards a target; and after the flying mesh finishes the envelopment for the target, a mass block for guiding the flying mesh to unfold can automatically tighten the opening of the mesh and lock the target by means of self residual kinetic energy, and meanwhile, a safety design and a reliability redundancy design are realized, so that the safety of the acquisition device is ensured. The flying mesh catapulting device has the advantages of light weight and small size so as to be convenient for realizing modular design; and the flying mesh catapulting device can be used as an on-track target acquisition executing mechanism of a space robot system and particularly suitable for an on-track acquisition and clearing tasks for the discarded spacecraft.

Description

technical field [0001] The invention relates to a flying net ejection capture device for capturing abandoned spacecraft, in particular to a flying net ejection capture device for on-orbit capture and orbit reset of abandoned spacecraft, and belongs to the field of space mechanism design. technical background [0002] In recent years, with the continuous occurrence of collisions between abandoned spacecraft in orbit, the issue of space debris has attracted more and more attention from various countries. Space debris refers to man-made objects lingering in space other than normal working spacecraft in space. Space debris is in an uncontrollable high-speed flight state, posing a deadly threat to normal working spacecraft. [0003] The analysis of the generation pattern of space debris shows that although the proportion of abandoned spacecraft (including exhausted and malfunctioning spacecraft, rocket final stage, etc.) in the total space debris is small, it is a key source of ...

AI Technical Summary

Problems solved by technology

However, the above scheme still has the following obvious defects: 1) The above scheme does not give how to judge that the flying net has completely enveloped the target

2) The closing speed of the winding motor is slow, which may easily cause the target to miss the target

3) Under the condition of space microgravity, the rotation of the motor will cause its own tumbling, which will cause the entanglement of the flying net

4) The design of the spring compression release device is relatively complicated, and any failure of any one will lead to capture failure, so the reliability is low
