AI Technical Summary
Existing on-orbit refueling mechanisms have small capture tolerance, high control difficulty, and insufficient safety and reliability, resulting in a low success rate for refueling missions.
A highly reliable claw-type on-orbit refueling mechanism was designed, comprising an active end and a passive end. It employs a claw assembly, an elastic support rod, a drive mechanism, and a backup drive mechanism. Capture, docking, and separation are achieved through the opening, closing, and vertical movement of the claw. It features large radial and axial tolerances, strong self-adaptability, and an emergency separation function.
It improves the capture tolerance of on-orbit refueling, reduces the control difficulty, ensures the safety and reliability of refueling missions, and achieves high-reliability capture, docking and separation throughout the entire process, enabling the mission to continue even in the event of a failure.
