Abstract
L'addition concerne un instrument inertie accordé. Selon l'addition, il comprend un boîtier 102; un arbre 11 supporté sur des paliers 104, pour une rotation autour d'un axe à une fréquence prédéterminée; un élément sensible 128; un moyen de suspension 106 comportant un moyen permettant une oscillation relative entre l'élément sensible et l'arbre autour d'au moins un axe du moyen de suspension qui n'est pas perpendiculaire à l'axe de rotation; un moyen 130 couplé à l'arbre pour provoquer un produit d'inertie autour de l'axe de rotation et d'un axe perpendiculaire à cet axe de rotation; et un moyen pour réduire la retenue angulaire apparente de la partie non rotative des paliers autour d'axes généralement perpendiculaires à l'axe de rotation. L'addition s'applique notamment aux instruments inertiels de précision tels que les gyroscopes et accéléromètres.
