A variable length stay for an aircraft landing gear is disclosed having first and second sets of struts lying on different longitudinal axes that enable the stay to extend and contract by movement of the struts parallel to their axes. The stay may be locked in its extended and retracted configurations thus providing downlock and uplock functions for the landing gear. The struts of the stay may have an open and easy to inspect structure, have low friction kinematics, and do not need to telescope within each other or lie on a single common axis.

A thin-skin support member is provided. The thin-skin support member may include a semi-circular edge and a flat edge that define a hollow cavity. A cylindrical cavity may be adjacent the hollow cavity and at least partially defined by the semi-circular edge. The cylindrical cavity may be configured to retain a strut assembly. A mounting interface may be coupled to the semi-circular edge and the flat edge. A torsion interface may be disposed adjacent the cylindrical cavity and configured to receive a torsion link. The thin-skin support member may be made using additive manufacturing and thus may have a grain structure grown in the direction of material being added.

The present disclosure describes methods for anodizing aluminum alloys, including 7000 series aluminum alloys, and creating metal components, including aircraft landing gear components, from the aluminum alloys.

A torque link assembly may comprise an upper torque link, a lower torque link, and a torque link pin. The upper torque link may define an upper hydraulic fluid channel. The lower torque link may define a lower hydraulic fluid channel. The torque link pin may fluidly couple the upper hydraulic fluid channel to the lower hydraulic fluid channel.

A torque link assembly for a landing gear includes a lower torque link and an upper torque link that releasably engage first and second quick release pin assemblies. The pin assemblies each include a housing attached to one of the torque links, and a locking pin member extending through the housing. The locking pin member includes a rod portion and a pin portion, and is slidable between an engaged position and a disengaged position for hingedly connecting/disconnecting the torque links. One of the housing and the locking pin member includes a channel having a longitudinal portion and a circumferential portion, and the other has a guide pin that engages the channel. The guide pin is in the longitudinal portion of the channel when moving between the engaged and disengaged positions, and is retained in the disengaged position when the guide pin is in the circumferential portion of the channel.

A system for shrinking landing gear includes a shock strut having a cylinder and a piston to be received by the cylinder. The system further includes a collar coupled to a brace linkage and the piston, a torque arm configured to resist rotation between the collar and the piston, and a shrink linkage coupled between the torque arm and the cylinder. The collar rotates relative to the cylinder in response to retraction of the landing gear. Rotation of the collar rotates the piston and the torque arm relative to the cylinder. The rotation of the collar relative to the cylinder forces, via the shrink linkage, the piston towards the aircraft attachment within the cylinder.

An aircraft landing gear includes a shock strut with a rod slidably received within a cylinder. A beam is rotatably mounted to the rod, and wheels are mounted to the beam. The landing gear further includes a link assembly with an upper link and a lower link. The upper link has a first end rotatably connected to the cylinder, and the lower link has a first end rotatably connected to the beam. The second ends of the upper and lower links are rotatably coupled to each other by a limiter joint. The limiter joint includes a first stop associated with the upper link and a second stop associated with the lower link. The stops are configured such that the first stop engages the second stop to limit rotation of the upper link relative to the lower link.

A bracket manifold for a landing gear assembly is disclosed. In various embodiments, the bracket manifold includes a mounting plate having a central portion and a first wing portion extending from the central portion; and a first manifold section integrated monolithically into at least one of the central portion and the first wing portion of the mounting plate.

A landing gear assembly (12) includes a primary load bearing strut including a shock absorber having a slider part (15) arranged to slide within a cylinder part (17). A link assembly (50) is attached between the slider part (15) and the cylinder part (17). A bogie (16) supporting wheels is mounted on the strut. The bogie may adopt different pitch angles. A pitch trimmer device (70) is attached to the bogie and to the link assembly, for example thus providing a relatively long moment arm (96) for control of the bogie pitch angle. The arrangement may be such that the pitch trimmer (70) is near mid-stroke as the aircraft achieves the full weight on wheels condition, whereas the pitch trimmer is at a fullest extent for flight case and for retraction. Onset of pitch trimmer closure/movement is used to detect the weight-on-wheels condition.
