Optimal geometry and materials for nanospacecraft magnetic damping systems
A magnetic damping system for nanospacecraft attitude stabilization is proposed, primarily based on the use of thin strips of amorphous Fe-B-Si soft magnetic ribbons. The size, range, and location of the strips is optimized, and a predictive formulation is provided. The most results of ground tests, comparing the performance of several soft magnetic materials, is that suitably heat-treated amorphous ribbons offer the simplest loss performance in the entire range of magnetic fields expected in orbit.
