    摘要: A rotor blade assembly includes a rotor blade (20) and a rotatable flap portion (34) located along a span of the rotor blade (20). A linear actuator (46) located inside the rotor blade (20) is operably connected to the flap portion (34) to rotate the flap portion (34) about a flap axis (44) and is absent oil, grease or other fluid lubricant. A rotary-winged aircraft (10) includes an airframe (14) and a main rotor assembly (12) operably connected to the airframe (14). The main rotor assembly includes a plurality of rotor blade assemblies rotatable about a rotor assembly axis (22). At least one rotor blade assembly of the plurality of rotor blade assemblies includes a rotor blade (20) and a rotatable flap portion (34) located along a span of the rotor blade (20). A linear actuator (46) positioned inside the rotor blade (20) is operably connected to the flap portion (34) to rotate the flap portion (34) about a flap axis (44) and is absent oil, grease or other fluid lubricant.

    摘要: A gurney flap assembly (50) includes an actuator (100), and a flexible body (155) attaching to the actuator (100), the body (155) having a downwardly depending flap (160) for moving into and out of an airstream in a pressure side (85) of a wing (75), wherein the flexible body (155) flexes in reaction to motion of the actuator (100). This increases the lift force of the rotor blade, wing or aerofoil blade.

    摘要: A bearing assembly (100) and a method of forming a bearing assembly is provided including a housing (110) having a bore (132). The bore has a generally concave inner surface (134). The bearing assembly also includes a bearing (140) having an inner member (142). The inner member is movable about a central axis (A) and is dimensioned to fit within the bore. The inner member has a generally convex outer surface (144) complementary to the concave inner surface (134) of the bore. The housing functions as an outer member of the bearing.

    摘要: A hinge for use with movable components is provided including a generally rectangular body (22). The body includes a bend region (28), a first flange (24), and a second flange (26). The first flange and the second flange are positioned on opposing sides of the bend region. A portion of the bend region has a reduced thickness relative to the first flange and the second flange. A hinge axis (A) is defined within the bend region. The first flange and the second flange rotate about the hinge axis.

    摘要: A gurney flap assembly (50) has an actuator (100) and a body (155). The body (155) has a leading edge and a trailing edge and includes a first panel (215) attaching to the actuator (100) proximate the leading edge, and a second panel (205) attaching to a first hinge (223) at the trailing edge. A second hinge (222) attaches the first and second panel (215, 205). Linear motion of an actuator output (110) is transposed to the gurney flap (150), thereby causing the gurney flap (150) to expand and deploy into the airstream on the pressure side of a wing (75).
