ABSTRACT:
A gyroscopic rate sensor has a motor driven shaft on which is mounted a flexible disc rotor enclosed in a gas-filled housing with a rotating rigid plate, also mounted on the shaft, to provide viscous gaseous restraint. A rotating capacitive plate assembly referenced to the drive motor spin axis provides a stable electrical output signal proportional to periodic deflections of the disc rotor. By perforating the disc rotor near the spin axis, spring restraint is minimized while the squeeze film damping provides improved dynamic response.
