Title (EN) SPACECRAFT COMPRISING ACTIVE ATTITUDE CONTROL MEANS AND PASSIVE ATTITUDE CONTROL MEANS
(FR) ENGIN SPATIAL COMPRENANT DES MOYENS DE CONTRÔLE ACTIF D'ATTITUDE ET DES MOYENS DE CONTRÔLE PASSIF D'ATTITUDE
Abstract:
(EN) The invention relates to a spacecraft (100) comprising a main body (110) and an attitude control system, said attitude control system including active attitude control means (150). In addition, the attitude control system also comprises passive attitude control means suitable for generating, in cooperation with the Earth's magnetic field, a damping torque and comprising at least one passive damper (200), the at least one passive damper (200) comprising an outer enclosure (210) and an inner body (220) configured such that: - the inner body (220) is positioned inside the outer enclosure (210) and is rotatable inside the outer enclosure (210) around at least one axis of rotation, - the outer enclosure (210) comprises an inner surface (211) and the inner body (220) comprises an outer surface (221), said surfaces being separated by means of a viscous fluid (230), - the inner body (220) is permanently magnetized, and - the outer enclosure (210) is constrained to rotate with the main body (110) of the spacecraft (100).
(FR) L'invention concerne un engin spatial (100) comprenant un corps principal (110) ainsi qu'un système de contrôle d'attitude, ledit système de contrôle d'attitude comportant des moyens de contrôle actif d'attitude (150). En outre, ledit système de contrôle d'attitude comporte également des moyens de contrôle passif d'attitude adaptés à générer, en coopération avec le champ magnétique terrestre, un couple d'amortissement et comportant au moins un amortisseur passif (200), ledit au moins un amortisseur passif (200) comportant une enceinte externe (210) et un corps interne (220) configurées de sorte que : - ledit corps interne (220) est positionné à l'intérieur de ladite enceinte externe (210) et mobile en rotation à l'intérieur de ladite enceinte externe (210) autour d'au moins un axe de rotation, - ladite enceinte externe (210) comporte une surface interne (211) et ledit corps interne (220) comporte une surface externe (221), lesdites surfaces étant séparées au moyen d'un fluide visqueux (230), - ledit corps interne (220) est aimanté de manière permanente, - ladite enceinte externe (210) est solidaire en rotation avec le corps principal (110) dudit engin spatial (100).
