Evolution of Perturbed Rotations of an Asymmetric Gyro in a Gravitational Field and a Resisting Medium

摘要

We study the fast rotational motion of a dynamically asymmetric satellite with a spherical cavity filled with a highly viscous liquid about the center of mass under the action of gravitational torque and medium drag torques. The system obtained by averaging over the Euler-Poinsotmotion and by using a modified averaging method is analyzed. An analytic study and numerical analysis are carried out.
