空间旋转目标涡流消旋概念与仿真分析.

This paper studies the problem of detumbling a non-cooperative space object with a high rotating speed. Firstly, the high temperature superconducting technology and eddy current brake technology are combined together and an eddy brake concept based on superconducting electromagnet is proposed. Then, the qualitative analysis on the technological feasibility of this eddy brake concept is conducted, and the advantages of this combined technology is concluded through the tradeoff analysis among several despin approaches. Furthermore, by applying the electromagnetic tensor theory, the exact magnetic field model and exact eddy current torque model that explicate the action mechanisms of the superconducting eddy brake are derived. Finally, considering the requirement of the practical despin task, the despinning simulation studies of the typical tumbling objects ranging from low speed spin to high speed spin and the objects rotating with nutational motion are performed. The simulation results indicate that the superconducting eddy brake can provide enough brake torque to the despin rotations up to 550 (°)/s or rotations combined with nutational motion.
