摘要： A levered landing gear including a first shock strut having and a second shock strut disposed concentrically with the first shock strut. The second shock strut includes a metering pin coupled to a mounting surface of a piston of the second shock strut, and an orifice plate that cooperates with the metering pin to meter an amount of fluid flow as the second shock strut is compressed. The metering pin includes flutes longitudinally arranged on the metering pin between first and second ends of the metering pin, the flutes having a varying depth so that a fluid flow through the flutes is greater at the second end than fluid flow through the flutes at the first end. A truck lever is coupled to both the first shock strut and the second shock strut such that the second shock strut pivots the truck lever relative to the first shock strut.

摘要： An aircraft landing gear assembly having a reinstating geometry in which a lock link can be moved to assume a first locking condition to inhibit movement of a stay when a main strut is in a deployed condition and a second locking condition to inhibit movement of the main strut when in a stowed condition. An unlock actuator is coupled between a first element of the stay and the lock link such that the actuator can break the lock link from the first locking condition and force it to assume the second locking condition by operational force in a single direction.

摘要： A retractable landing gear system configured to contour an aircraft fuselage includes a landing wheel having an axle, a wheel rotation strut assembly coupling the landing wheel to the aircraft fuselage and an actuation strut assembly configured to move the wheel rotation strut assembly between various positions including a deployed position and a stowed position. The axle of the landing wheel is pivotably coupled to a distal end of the wheel rotation strut assembly and configured to pivot relative to the wheel rotation strut assembly as the actuation strut assembly moves the wheel rotation strut assembly between the deployed and stowed positions such that the landing wheel generally contours the aircraft fuselage when the wheel rotation strut assembly is in the stowed position.

摘要： An amphibious aircraft has a tricycle landing gear that is movable between a retracted, or up, position and an extended, or down, position. Each member of the landing gear is protected in the forward direction by a hydrodynamic protector, or vane, or shoe, such as may tend to create lift when brought into engagement with water, as during landing. The landing gear protector vanes may be mounted to move with extension and retraction of the landing gear. The landing gear wheels may protrude to extend partially downwardly proud of the sole of the shoe. The landing gear actuator and transmission may operate all gear in concert. The shoes may include sacrificial wear members for ground engagement in the event of an inadvertent gear-up landing on terrain.
