摘要: A bearing system includes an inboard bearing assembly (120) and an outboard bearing assembly (114). The inboard bearing assembly (120) includes an inboard fitting (122) and an inboard race (124). The inboard fitting includes a plate (126) with a convex mating surface (142) and a first aperture (128) formed through the plate for receiving a blade root (112) of a rotor blade (108). The inboard race comprises a concave mating surface (144) configured to receive the convex mating surface (142), a second aperture (125) formed in the inboard race (124). The outboard bearing assembly includes an outboard bearing assembly (114) comprising an outboard fitting (118) having an aperture formed therethrough for receiving the blade root (112) of the rotor blade (108).

摘要: A propeller assembly of an aircraft includes a hub (18), a plurality of propeller blades (20) extending from the hub and secured thereto and a propeller blade pitch change system located at at least one propeller blade of the plurality of propeller blades. The propeller blade pitch change system includes a pitch change actuator (36) located in the propeller blade, and a drive mechanism (46, 48, 50) operably connected to the pitch change actuator and to the propeller blade to urge rotation of the propeller blade about a propeller blade axis.
