The Float-Cocking Phenomenon in Single-Axis Floated Gyroscopes 650589
Some single-axis floated integrating rate gyroscopes are designed with float suspension systems that have sensible radial compliance. When angular velocities are impressed about the output axis of these units, the resulting gyroscopic torque about the input axis causes the float to cock within the gyro housing. This paper presents complete equations of motion for the single-axis floated gyro, taking into account the float-cocking degree of freedom. Previously observed test results are explained analytically. Approximate expressions for the squeeze-film damping constant, not available in the literature, are developed in Appendix B.
