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

Embodiment Construction
[0035] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0036] refer to figure 1 , is an embodiment of the present invention, and the spatial target capture rope net includes a central mass block 4 at the geometric center of the capture net 1 described in the capture net 1, and a space target capture rope net is realized by the central mass block 4. level launch. The periphery of the capture net 1 is evenly provided with a plurality of traction mass blocks 5, through which the multiple traction mass blocks 5 in the periphery realize the secondary launch of the space target capture rope net, so that the capture net 1 can be fully and fully deployed.
[0037] The catching net 1 is provided with an adaptive claw 2 that can be stretched along with the launch of the catching net. After the catching paving net 1 collides with a space target, the catching net 1 is retracted under the inertia of the catchi...

The invention provides a space target capture rope net. The space target capture rope net comprises a capture net, an adaptive claw is arranged on a net body of the capture net, the adaptive claw canstretch along with launching of the capture net, after the adaptive claw collides with a space target, the adaptive claw embraces towards the space target in the capture net, and the target is captured. Compared with traditional rope net capture, after the space target capture rope net collides with the capture target, it can be ensured that the target is captured completely through the large-areacoverage characteristic of the rope net, and it is ensured that the capture rope net and the capture target can form a more-stable composite body through the self-locking function of the adaptive claw. Through the characteristic, the complexity of subsequent control such as racemization control and orbit transfer control is greatly lowered on the basis of completing target capture, and the successful rate of space target capture deorbiting is greatly increased.
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...
