Redesign of Glenn research center D1 flywheel module

Glenn Research Center has completed the redesign of the D1 flywheel module. The redesign includes a new rotor with a composite rim, motor/generator, touchdown bearings, sensors, and a magnetic actuator. The purpose of the relatively low cost module upgrade is to enable it to continuously operate throughout its speed range of 0-60,000 RPM. The module will be used as part of a combined attitude control and bus regulation experiment.
