Despun capture integrated device

Abstract

The invention provides a despun capture integrated device. The despun capture integrated device comprises a capture mechanism, a coupling and a despun mechanism, and the despun mechanism comprises anelectric generating machine mounted on a servicing spacecraft; the capture mechanism is connected with the despun mechanism through the coupling, after a target is captured by the capture mechanism, the despun mechanism is driven by rotation of the target to generate electricity, and thus rotation of the target is eliminated. According to the despun capture integrated device, the structure is compact, automatic centering is achieved, clamping is reliable, energy consumption is low, applicability of interfaces is wide, the despun capture integrated device can be used for targets in high speed self-spin or plane-spin states and the targets which the interface of a rotary body shape is located on a rotary shaft, continuous capturing and releasing of the targets can be achieved, stability of the targets and accuracy of gesture are guaranteed, and the despun capture integrated device has great application value in space operation tasks such as repairing, auxiliary on-orbit and off orbit offailed satellites.

Description

technical field [0001] The invention relates to aerospace technology, in particular to a device for capturing high-speed spinning or flat-rotating non-cooperative targets by using a fast locking mechanism. Background technique [0002] The exploration activities of human beings in outer space are gradually increasing, which brings benefits and also has a lasting and far-reaching impact on the space environment. The remaining rocket stages, failed satellites, spacecraft mission discards, spacecraft disintegration and collision derivatives in space A large number of space debris such as space debris have posed a huge threat to the development of human spaceflight. Therefore, the active removal technology of space debris has become a research hotspot in the aerospace field. The primary key to the active removal of space debris is the implementation of on-orbit capture, and most of the space debris are non-cooperative targets. Since the target has lost the ability to adjust its...

Problems solved by technology

Rigid capture has higher requirements for target cooperation, while flying nets and flying claws have looser requirements on target speed and target size than rigid capture, but it is difficult to carry out maintenance, detection and reuse of targets after capture

(2) The non-contact method uses gas impact, electrostatic force, electromagnetic force, laser and other non-contact forces to derotate the target, which can effectively reduce the risk of collision and eliminate the three-axis rotational speed of the target from a safe distance. The spin process lasts longer

[0006] Among them, the rigid capture and flexible capture in the contact capture method will have a great impact on the service spacecraft during the despin and capture process of the high-speed spinning or flat-rotating out-of-control satellite, and even cause its It collides with the high-speed spinning target, causing damage to the service spacecraft and producing a large amount of space debris, and the flexible capture connection has poor stiffness and poor capture reliability, which is not conducive to the precise operation of the target after capture, so it is not applicable

[0007] Among them, the non-contact capture method consumes a lot of energy in the despinning and capture process of high-speed spin or high-speed flat-spin out-of-control satellites, the despin process lasts for a long time, and generally requires two sets of independent magnetic field generating devices and capture devices. The devices are used for the derotation operation and capture operation respectively, which virtually increases the complexity of the service spacecraft, and also increases the complexity of the space failure target derotation capture task
