ABSTRACT:
Preloading and retention of an aircraft propeller blade (12) are achieved by a preloading mechanism (85) received within an outer portion of a hub barrel(30) within which the blade is received. The preloading mechanism comprises an annular fastener (90) threaded into the barrel. A splined lock ring (125) prevents loosening or disengagement of the fastener from the barrel. Location of the preloading mechainsm at an outer location of the barrel allows the primary centrifugal load path from the blade into the barrel to be free from discontinuities and attendant stress concentrations.
