Abstract
The special dissipative method of nanosatellites angular momentum unloading is considered. The method implies the interaction of the main body of a nanosatellite with the internal damper, rotating relative the main body in the cavity with dissipative resistance medium (liquid, etc.). The damper body represents the three-axial body with the different general inertia moments, which try to take its orient according to the action of gravitation central forces. So, the damper-body rotates in the inertial space due to gravitational forces, and therefore, it fulfills the rotation relative the main body of the nanosatellite. Then between the main body and the damper-body, the dissipative torque is acted due to resistance of liquid-type friction, which unloads the angular momentum of the satellite. The presented method for unloading the angular momentum is quite simple from the constructional point of view, also it is dynamically natural and clear, and, moreover, this is the first exploration of the idea of gravitationally dissipative unloading scheme for nanosatellites.
