ABSTRACT:
A flexibly suspended gyroscope apparatus comprises a fixed body (100), a rotary drive shaft (200) supported in said body, and a flywheel (220) mounted on said drive shaft by a rotary joint (222). The joint serves to retain the flywheel radially and to transmit rotary drive thereto, while leaving said flywheel free to oscillate with two degrees of freedom about a central position in which the axis of the flywheel is aligned with the axis of the drive shaft. The flywheel is also free for axial translation with one degree of freedom. Axial support means (101, 102, 103, 104) are provided for applying an axial force to the flywheel by electrostatic or electromagnetic induction, and axial position detector means are provided for detecting the axial position of the flywheel, said support means being servo controlled by said detector means to maintain the flywheel in a predetermined axial position. Advantageously the same or similar means also apply precession torques to the flywheel, thereby constituting a rate gyro.
