Gyroscope apparatus includes a tubular rotor that is supported at opposite ends by bearings, such as a gas-lubricated bearing, for rotation about its axis. A gimbal ring encircles the rotor and is resiliently supported with the rotor, for angular displacement about an axis at right angles to the rotor axis, by a pair of flexure pivots located intermediate the ends of the rotor. An inertia ring is mounted concentrically with the gimbal ring by another pair of flexure pivots for angular displacement about an axis at right angles to the rotor axis and the axis of displacement of the gimbal ring. The major part of each flexure pivot is contained within the radial thickness of the gimbal ring. Displacement of the inertia ring is sensed by pick-offs the outputs of which are used to control the restoring torque applied by torquers located outwardly of the pick-offs. |
