The detailed results of the spin test evaluation of the Hercules Aerospace flywheel at the Oak Ridge Flywheel Evaluation Laboratory (ORFEL) are presented. Details of the static evaluation with radiography and measures of weight, inertia, and natural frequencies are included. The flywheel was spun four times with the maximum speed being increased with each run. During the final run, the flywheel achieved 372 rps and stored 0.714 kWhr of kinetic energy at 37 Whr/kg. The ultimate speed was limited by a composite transverse strength that was somewhat lower than that used in the design of the flywheel. This resulted in internal cracking of the flywheel and, eventually, the loss of material from the outer circumference. (ERA citation 07:004337)
