The work described is concerned primarily with fluid rotor angular velocity and piezoelectric crystal linear acceleration sensing techniques. The technical and investigative effort was directed at establishing the feasibility of and measuring the performance of extremely small sensors which contained in one instrument, the capability of measuring two orthogonal axes of angular velocity and two orthogonal axes of linear acceleration. Laboratory models of these multifunction sensors were fabricated and tested. Both ball bearing and hydrodynamic gas bearing spin axis suspension systems were investigated. The significant results obtained for an instrument of microminiature size were those of wide band frequency response, low thresholds, and adequate linearity and cross coupling parameters. It was concluded that the sensor concept investigated is capable of an extremely wide range of high performance applications, while offering some very unique advantages in its simplicity as a multi-function instrument, in small size and weight, in low power consumption and in its insensitivity to extreme inertial environments.
