Nutational Damping of a Slowly Spinning Satellite Stabilized by Use of a Rotor

摘要

The nutational damping of a slowly spinning satellite, stabilized with a small rotor, is analyzed. The characteristic equation for the case of damper motion in a plane passing through the spin axis is seen to be similar to that of damper motion in a plane perpendicular to the spin axis. A parametric study of the characteristic equation is made for the case of one and two dampers. The damping characteristics of the one damper, with counterweight, appears to be preferable. (Author)
