Flexible pneumatic capturing mechanism for capturing non-cooperative target in space

Abstract

The invention discloses a flexible pneumatic capturing mechanism for capturing a non-cooperative target in a space, and belongs to the technical field of capturing systems for the non-cooperative target in the space. According to the flexible pneumatic capturing mechanism, the front end extends to be close to a non-cooperative target, and the tail end captures the non-cooperative target. The main air bag is a main body part of the stretching mechanism and can be unfolded and stretched after being inflated, the auxiliary air bag is a steering control part of the stretching mechanism, the two ends of the main air bag and the auxiliary air bag are connected with end covers, the end cover located at the tail end is connected with a capturing satellite, and the end cover located at the head end is used for installing a capturing device. The flexible protection cover is arranged between the two end covers and used for covering the outer sides of the main air bag and the auxiliary air bag. The unmanned aerial vehicle has the advantages of low control requirement on a capture satellite, light weight, small loading volume, no need of a thermal insulation system, high safety, multi-arm coordination, simple structure, low cost and strong structural designability.

Description

technical field [0001] The invention belongs to the technical field of capture systems for space non-cooperative targets, and in particular relates to a flexible pneumatic capture mechanism. Background technique [0002] Non-cooperative targets generally refer to space targets that cannot provide effective information. Research on non-cooperative targets is the basic prerequisite for many popular space technologies such as autonomous navigation, space-based precise measurement, interstellar flight, autonomous rendezvous and docking, space countermeasures, and small satellite orbiting in the future. [0003] At present, the capture of non-cooperative targets in space mainly adopts mechanical capture systems, such as claw-holding systems. These mechanical capture systems usually have the disadvantages of heavy weight, large volume, high energy consumption, and easy damage to non-cooperative targets during accidental collisions. In addition, mechanical capture often requires ...

Problems solved by technology

[0005] However, some existing flexible capture mechanisms also have some problems, such as the bionic flying net capture system. After capture, the flying net is entangled with non-cooperative targets (such as non-cooperative satellites), and it is difficult to release non-cooperative targets; Claw-clamping inflatable catcher, this kind of catcher is actually multiple inflatable extension arms, they are directly connected to the satellite, and capture by "hugging" the non-cooperative target, which requires the satellite to be as close as possible to the non-cooperative target, and to adjust the capture posture, it will also consume more energy

In addition, the inflatable catcher composed of multiple inflatable stretching arms has a catch force related to the internal pressure of the stretch arms. In order to ensure safety, the internal pressure of the inflatable structure should not be too large, so the catch force is limited.
