The steady-state whirl-spin relationships for the pendulously supported flywheel with bearing flexibilities, stiff sections of shaft and gyroscopic action are derived and experimentally verified. Stable and unstable operations of the system are experimentally demonstrated, and damping necessary to stabilize an inherently unstable system is theoretically derived for two modes of bearing displacements.
