Abstract:
1. A control moment gyro comprising: a chock having a lower base, an upper face provided with a central orifice, and lateral walls extending from the lower base to the upper face; a gimbal assembly comprising a stator; an inertia wheel mounted, by means of a wheel support, on a movable portion named rotor of said gimbal assembly that also comprises driving means for rotating said rotor relative to said stator about a first axis of rotation, said inertia wheel having a spinner able to be rotated about a second axis of rotation not aligned with said first axis of rotation; at least one vibration-attenuation element distinct from the chock and arranged in contact with said lateral walls and adjacent the upper face; wherein said stator of said gimbal assembly is mounted on said chock through the central orifice and attached to said chock by said at least one vibration-attenuation element, and said driving means for rotating said rotor are at least partially housed in an internal volume of said chock.
