Drift of a dynamically regulated gyroscope, caused by residual stresses in the torsional elements of the suspension, and diagnostics of the drift
Abstract
Dynamically regulated gyroscopes with a horizontal spin axis are characterized by an appreciable drift which is not amenable to elimination either by balancing or regulation and which cannot be explained in terms of damping or the earth's rotation. In the present paper, the nature of this drift is studied by analyzing the behavior of an ideally balanced and regulated gyroscope free of damping. The drift is shown to result from residual stresses arising in the torsional elements of the gyro.
