The purpose of this program was to investigate the performance of high-speed overrunning clutch assemblies for use in a multiengine helicopter. The design operating conditions were 3,570 inch-pounds torque transmitted at 26,500 rpm. Two clutch configurations with differing design philosophies were evaluated. One design utilizes inner and outer sprag retainers with a central energizing ribbon spring. The other design positions the sprags with one retainer and incorporates garter springs at the sprag edges. An analysis of high-speed sprag clutch operation was performed, and a computer program was developed as an initial step to provide a mathematical model of clutch operation reflecting modern, high-speed mechanical component technology.
