Retention assembly for a propeller blade

摘要

A retention assembly (32) for a propeller blade (30) includes an inner ring (40) that is conformally shaped to a bore (41) of an annular loop (38), the annular loop (38) being associated with a root portion (36) of the propeller blade (30); a base (44) that is configured to be immediately adjacent the annular loop (38); an outer ring (42) that includes an extended tapered portion (72) which decreases in radial thickness from an inboard end (74) to an outboard end (76); and an adhesive that adhesively connects complementary surfaces of the outer ring (42) and the annular loop (38). Also, a propeller blade assembly (22) includes a propeller blade (30) having a blade portion (34) and a root portion (36) and the retention assembly (32) configured to be attached to the propeller blade (30).
