    摘要： A fitting assembly (100) includes a fitting (110) with at least one pocket (120). The pocket includes a web (122) extending inward from a perimeter of the pocket, and the web has a cutout (124) that defines an inner edge. A stiffener (150) is mounted within the pocket. The stiffener includes a lattice (152) and a coupler (160) that is configured to engage at least a portion of the web to mount the lattice to the fitting.

    摘要： A shock strut (100) for a vehicle includes a housing (130) with a through channel (131) and a motor mount (134), and a motor (150) fixed to the housing (130). The cylinder (106) of a shock strut (100) is configured to define a lead screw (107) on its outer surface. The cylinder (106) extends through the housing (130). The piston (104) of the shock strut (100) is attached to a ground engaging assembly (110). A gear nut (140) rotatably mounted in the housing (130) threadably engages the threaded cylinder (106), and is configured to be driven by the motor (150). The housing (130) is attached to the vehicle, and the gear nut (140) is controllably rotated to extend and retract the shock strut (100). A sensor (155) provided on the assembly monitors the position of the shock strut (100). A torsion link assembly (120) reacts rotational forces on the cylinder (106).

    摘要： A retractable landing gear (100) includes a main strut (110) having an upper end (103) that is configured to connect to aircraft primary structure and a lower end (102) configured to connect to an axle or bogie truck. An articulated stay (120) has a distal end configured to connect to the aircraft structure and a proximal end pivotally connected to a cardan pin member (150). The cardan pin member has a cylindrical portion with a first recessed annular channel (154). The cardan pin member is retained in the socket (160) by a ring assembly formed by two semi-annular ring members (155) that slidably engages the first recessed channel. The ring assembly defines a second recessed annular channel (156). A collar (157) is configured to be positioned over the second recessed channel, and to contract upon a change in temperature to lockingly engage the second recessed channel, to secure the split ring assembly in the first recessed channel.

    摘要： A hydraulic shimmy damper that resolves drawbacks in several known shimmy dampers, such as damping characteristics that are dependent on oil temperature variations. The disclosed shimmy damper includes a hydraulic compensator (40) having an internal fluid volume that is significantly more important than a fluid volume expelled from the body of the shimmy damper when its piston moves fore and aft. The shimmy damper also includes a hydraulic manifold (30) arranged between the body and the hydraulic compensator and defining a transfer channel between chambers in the piston that is connected to the hydraulic compensator. The manifold receives interchangeable hydraulic cartridge-type valves (CV1,RV1; CV2,RV2) for metering the fluid flowing from the chambers to the transfer channel, and allows the fluid to freely enter the chambers from the transfer channel. The present shimmy damper is therefore much less sensitive to oil temperature variation under intense shimmy.
