摘要： A propeller rotor (99) has a hub (112) mounting a plurality of blades (106). A counterweight (100) is movably mounted on the blade (106). A pitch change mechanism (108; 110) for changing an angle of incidence of an airfoil is associated with each of the blades (106). The counterweight (100) twists the blades (106) toward an increased pitch direction should the pitch change mechanism (108; 110) fail. A stop member stops rotation of the counterweight (100) as the blade (106) moves to a feather position.

摘要： A propeller system, 10, for an aircraft includes a propeller assembly rotatable about a central axis and a reduction gearbox, 16, operably connected to the propeller assembly via a propeller shaft, 18. An electrical power transfer system is positioned such that the gearbox, 16, is located axially between the electrical power transfer system and the propeller assembly. The electrical power transfer system includes a slip ring assembly operably connected to an oil transfer tube, 24, extending to the propeller assembly and a brush block, 34, interactive with the slip ring assembly to transfer electrical power to a plurality of lead wires extending from the slip ring assembly to the propeller assembly, The brush block, 34, is positioned such that brush block tips, 46, of the brush block, 34, extend toward the slip ring assembly in a substantially axial direction relative to the central axis.

摘要： An example airfoil assembly (20) includes an airfoil body (22) extending between a leading edge, a trailing edge, a suction side, and a pressure side. The assembly further includes a first protective sheath (34), an indicator sheath (72), and a second protective sheath (60). The first protective sheath (34) has an outer side (36) and an inner side (38) that forms a cavity for receiving at least a portion of the airfoil body (22). The inner side being bonded to the leading edge of the airfoil body. A portion of the indicator sheath (72) is positioned forward the first sheath (34) relative to the leading edge of the airfoil. A portion of the second protective sheath (60) is positioned forward the indicator sheath (72) relative to the leading edge of the airfoil.

摘要： A split slip ring assembly formed from first and second halves of a slip ring having a contact surface (31a,31b,31c) for rotational engagement with a stationary brush element for transferring electrical signals therebetween. The contact surface has a smooth surface at the junction (49) of the first and second halves. A fastener (51,53) locates the first and second halves to form a ring shape. An electrical contact on the ring carries electrical signals between the slip ring and the brush element. An alignment element aligns the first and second halves to form the smooth surface at their junction (331a,331b,331c).

摘要： A fan blade (30) for a turbine engine (10) includes an exterior surface defining an airfoil that is provided by leading (38) and trailing (40) edges, opposing generally chord-wise surfaces (42) interconnecting the leading and trailing edges, and a tip (36). The airfoil extends from a root (34). A fan rotor (28) includes a slot that receives the root. A spar (46) is constructed from a first material and includes opposing sides. The spar provides at least a portion of the exterior surface. A sheath (44) is constructed from a second material different from the first material. The sheath is arranged on both of the opposing sides of the spar to provide at least a portion of the exterior surface at the opposing surfaces.
