Abstract

In order to solve the problem of poor versatility and adaptability of spacecraft acquisition system, the invention provides a spacecraft capture system based on nozzle capture and satellite-rocket docking ring locking, which relates to the technical field of non-cooperative spacecraft acquisition. The invention comprises a six-degree-of-freedom adjusting device, which is used for adjusting the position and the posture of the locking device so as to make the locking device contact with the butt joint surface of the satellite-arrow butt joint ring; a capture device, when opposite to the nozzle position, is used for detecting the position of the nozzle throat of the spacecraft, controlling the airbag to enter the nozzle throat of the spacecraft and inflate the airbag, and using the airbag tolock the nozzle throat to realize capture; a locking device for locking the outer edge of the satellite-arrow docking ring from a radial direction using a locking member when the locking device is incontact with the docking surface of the satellite-arrow docking ring. The invention releases the capturing device to the nozzle throat of the target, and captures the target nozzle; by recovering thecapture device, the docking range of the capture device to the locking device is tightened; the locking device locks the target's satellite-arrow docking ring through the locking member.

Description

Technical field [0001] The invention relates to a spacecraft capture system, in particular to a spacecraft capture system based on nozzle capture and star and arrow docking ring locking, and relates to the technical field of non-cooperative spacecraft capture. Background technique [0002] After entering the 21st century, with the vigorous development of space technology, countries around the world are developing and exploring deep space more and more frequently, and space systems are becoming more and more complex. However, the risk of aerospace technology is very high. While bringing huge benefits, it will also cause huge losses due to spacecraft launch failures, orbital failures, and limited spacecraft life. Therefore, in order to minimize the losses caused by spacecraft failures or failures, it is necessary to carry out many on-orbit service technology researches aimed at extending the life of spacecraft and removing orbital debris (such as abandoned spacecraft and space debr...
