The Rocketdyne Division of Rockwell International Corporation is developing an advanced 30 kW-hr high-energy-storage flywheel module for the U.S. Army. The module is designed to utilize the Rocketdyne-modified constantstress isotropic rotor system with a signed to utilize the Rocketdyne-modified constant stress isotropic rotor system with a disc energy of 11.6 W-hr/lb at its rated speed. The flywheel system incorporates two counter-rotating assemblies connected through a common gearbox with each rotating assembly being comprised of two flywheel discs. The Rocketdyne-modified constant stress flywheel system has been fully tested on a subscale basis with the results of an energy storage density at disc failure in excess of 21 W-hr/lb. A significant advantage of the rotor system is the fail-safe mode of failure which has been demonstrated through sub-scale testing. (DePo)
