An investigation of free whirling, forced whirling, and stability analyses of two ring type composite-material flywheel systems installed in a quill-shaft, air-turbine-drive test facility is presented. These systems differ from turbine/compressor systems in two respects: (1) the flywheel rim attachment to its hub is very flexible for both translation and tilting, and (2) these flexibilities depend upon rotational speed through centrifugal stiffening. It is believed that the eight-degree-of-freedom analysis presented here is the most comprehensive for such systems, and numerical results are presented for specific flywheel systems under development at Sandia Laboratories. Critical speeds encountered in the 8000 to 32,000 rpm range and a method of overcoming the adverse effect of material internal damping on the system stability by providing an adequate external damper are discussed.
