Evolution of perturbed rotations of an asymmetric Gyro in a gravitational field and a resisting medium

Resumo

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.
