Embodiment Construction

[0049] The weak-impact general capture mechanism suitable for high-orbit satellites according to the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] According to the present invention, the capture target of the weak-impact universal capture mechanism suitable for high-orbit satellites is the apogee engine of the high-orbit satellite, and the capture and locking position is the inner throat of the engine. The key point is to ensure light touch when capturing the apogee engine and low disturbance to target attitude control. For this reason, in the weak-impact universal catching mechanism according to the present invention, a guide damping device is provided so as to absorb the impact energy of the collision during the catching process. The pawl tensioning device is installed at the front end of the extendable spaceborne device, and the extendable spaceborne device provides the pawl tensi...

Abstract

A universal weak-impact capture mechanism applicable to high-orbit satellites comprises a guide damping device, a ratchet expansion device shell, an extensible satellite-bone device and three ratchet expansion devices arranged inside the guide damping device, the ratchet expansion device shell and the extensible satellite-bone device. A capture target is an apogee engine, and a capture locking position is a throat inside the engine. The extensible satellite-bone device play roles in bearing force, extending and retracting and connecting with an aircraft. The ratchet expansion devices function in capturing and locking and are mounted at the front end of the extensible satellite-bone device. The guide damping device functions in guiding and absorbing impact energy. The universal weak-impact capture mechanism realizes locking or expanding of a petal-type locking block by front-back movement of the guide damping device so as to capture and lock the target satellite. The universal weak-impact capture mechanism has the advantages of energy absorption, damping, simplicity and reliability in locking, high universality and easiness in attitude control and can be used as a standard docking capture device for the high-orbit satellites.

Description

technical field [0001] The invention belongs to the technical field of space satellite capture, and in particular relates to the structural design of a weak impact universal capture mechanism suitable for high-orbit satellites, especially the selection of energy-absorbing and shock-absorbing methods and the capture, locking and release of apogee engines realization. Background technique [0002] High-orbit satellites play an important role in military and civilian fields such as communications, navigation, early warning, and remote sensing due to their large satellite coverage and relatively slow motion on the ground. Carrying out on-orbit service for high-orbit satellites can prolong the life of the satellite and improve the ability to perform tasks, which is one of the current research hotspots at home and abroad. In the process of on-orbit service for high-orbit satellites, operations such as auxiliary orbit change, fuel supply, attitude control, satellite takeover, and ...
