Title

A Viscous Ring Damper for a Freely Precessing Satellite

Abstract

A viscous ring damper for removing the wobble motion of a spin-stabilized satellite is proposed and analyzed. The analysis is performed by studying the energy dissipation in an auxiliary problem of the motion of a viscous liquid in a tube whose boundaries perform harmonic motion. The energy dissipated per unit mass of the damper fluid is maximized in terms of a -œwobble Reynolds number-. This maximization is experimentally verified. The decay of the cone angle of free precession is then obtained by the use of the -œenergy-sink-approximation-. The results of the theory are compared with those from a laboratory experiment.
