Abstract:

This report documents a study to find overruning clutch concepts suitable for use in helicopters. Ten designs were selected for in-depth evaluation, and from these, three were selected for fabrication and testing the spring, the sprag, and the ramp-roller clutches. These performed satisfactorily in the tests, and a design guide was compiled for them USAAMRDL-TR-77-18. Author
