Abstract
The system comprises a grip of composite material having belts, filament windings unidirectional material and fillers of off axis bias ply material for directing the CF exerted on the grip by the blade rotation to the clevis throat of the grip. The force is further directed through a CF fitting, a CF bearing and an OPCBA to the yoke, thereby maintaining the yoke in tension. Should this load path fail, the CF will be transmitted through the length of the grip to the IPCBA that will in turn load the yoke with the CF.
