Space shape following capturing net

Abstract

The invention provides a space shape following capturing net, which comprises a capturing net body. A close-up mechanism is arranged on the periphery of the capturing net body, and an adaptive claw isarranged on a net body of the capturing net body; the adaptive claw can stretch out along with launching of the capturing net body; after the capturing net body collides with a space target, the adaptive claw embraces the space target in the capturing net body; and the capturing net body wraps the target and is closed up through the close-up mechanism to capture the target. It can be ensured thatthe target is completely captured through the large-area covering characteristic of the capturing net body, by combining with the self-locking function of the adaptive claw and through the close-up mechanism, the capturing net body is closed up, it is ensured that the capturing rope net body and the captured target can form a more stable composite, and non-cooperative targets are accurately, reliably and efficiently captured on rails.

Description

technical field [0001] The invention relates to the technical field of spacecraft capture devices, in particular to a capture rope net 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 their spatia...

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
