Abstract:

The Nutatron gyro features an anisometric rotor which responds to torques by exhibiting minute signals at twice the rotor frequency. These signals are used to automatically compensate for the drift producing torques and as a result the Nutatron is a high performance, low cost gyro with fast reaction time. Under previous contracts, the feasibility of the concept was demonstrated and an engineering model was designed, fabricated, and tested. This report covers a phase of the instrument development which had as its goal the investigation of the effect of bearing imperfections on the instrument performance. During this program unique analyses of bearing noise were made and the results of these analyses show which bearing parameters are important to achieving good Nutatron performance.
