Abstract: A two-axis angular rate gyroscopic apparatus is provided having a rotatable disk, said disk having a central hub portion and a plurality of flexible members, each of which extends from said hub portion. The entire disk is electrically conductive and connected to a reference potential. A plurality of electrically conductive members which are mounted end-to-end are located on an insulated plate mounted adjacent to the disk. A motor is provided for rotating the disk at approximately 2000 rpm. In addition, each of the flexible members in the disk has a pie-shaped section removed therefrom in order to increase its flexibility. By increasing the flexibility of the movable members, performance at low motor speeds is facilitated. An electronic circuit provides an output corresponding to the differential capacitance between the rotating disk and the members on the plate mounted adjacent thereto.
