This report discusses the results of the definition of requirements and design phases of the Advanced Overrunning Clutch Technology program conducted by Sikorsky Aircraft for the Eustis Directorate. The purpose of this program is to develop helicopter overrunning clutches for use at engine speeds. Current practice is to design the free-wheel unit to operate at the second stage of gearing with speeds from 6,000 to 8,000 rpm. At the engine speed, torque is lower and hence the free-wheel unit will be lighter.
