SPACE ENGINE COMPRISING MEANS OF ATTITUDE ACTIVE MONITORING AND PASSIVE ATTITUDE CONTROL MEANS

摘要

The invention relates to a spacecraft (100) comprising a main body (110) and an attitude control system, said attitude control system comprising active attitude control means (150). In addition, said attitude control system also comprises passive attitude control means adapted to generate, in cooperation with the earth's magnetic field, a damping torque and comprising at least one passive damper (200), said less a passive damper (200) comprising an external enclosure (210) and an internal body (220) configured so that: - said inner body (220) is positioned inside said outer enclosure (210) and rotatable within said outer enclosure (210) about at least one axis of rotation, - said outer enclosure (210) has an inner surface (211) and said inner body (220) has an outer surface (221), said surfaces being separated by means of a viscous fluid (230), - said internal body (220) is permanently magnetized, - said external enclosure (210) is integral in rotation with the main body (110) of said spacecraft ( 100).
