| Abstract: | Rapid rotational motion of a dynamically asymmetric satellite relative to the center of mass is studied. The satellite has
a cavity filled with viscous fluid at low Reynolds numbers, and it moves under the action of moments of gravity and light
pressure forces. Orbital motions with an arbitrary eccentricity are supposed to be specified. The system, obtained after averaging
over the Euler-Poinsot motion and applying the modified averaging method, is analyzed. The numerical analysis in the general
case is performed, and the analytical study in the axial rotation vicinity is carried out. The motion in the specific case
of a dynamically symmetric satellite is considered. |
