Configuration Design and Dynamics Analysis of Rotating Permanent Magnet Arrays for Space Debris Along-Orbit Removal

The deteriorating environment of space debris poses a significant threat to spacecraft. Several permanent magnets rotating at constant speed are formed into an array appropriately to remove the space debris, creating an induced force on the debris and pulling the debris into the collector. The force/torque model of magnetic dipoles and solid conductive sphere debris is established based on the existing research results. The relative motion model of debris and collection spacecraft in space orbit environment is established based on the C-W equation. The rotating permanent magnet array configuration is designed. The debris removal dynamics along the orbit is analyzed.
