Abstract: Systems and methods for enabling aircraft shock strut shrink are provided. The system may comprise a shock strut comprising a shrink piston, an accumulator comprising a gas piston and a hydraulic chamber, wherein the gas piston is configured to apply gas pressure to the hydraulic chamber, and a first valve in fluid communication with the accumulator. The system may further comprise a second valve, wherein the second valve is in fluid communication with a vent, the pneumatic cylinder, and the gas piston, wherein the first valve is in fluid communication with the hydraulic chamber and the shrink piston.

Abstract: A shock strut may comprise a strut cylinder, a strut piston operatively coupled to the strut cylinder, a shrink piston disposed at least partially within the strut cylinder, and a shrink chamber at least partially defined by the shrink piston. The shrink piston may comprise a shrink piston head, a sleeve extending from the shrink piston head, and a mechanical stop. A hydraulic fluid may be moved into the shrink chamber to compress the shrink piston and the strut piston into the strut cylinder to reduce an overall length of the shock strut.

Abstract: A landing gear arrangement may comprise a lever configured to be coupled between an axle and a strut piston of a shock strut, a load damper configured to be externally coupled between the shock strut and the lever, wherein the load damper is configured to increase a length of the landing gear arrangement in response to an extension force of the load damper increasing above a ground force reacted through the landing gear arrangement. The load damper may be located externally from the strut piston.

Abstract: The landing gear systems, methods and apparatuses disclosed herein may comprise a shrink pump and an unshrink valve that are capable of shrinking a landing gear shock strut up to about 40% of its available stroke. The shrink pump may be configured to pump fluid (e.g., a hydraulic fluid) between an oil chamber, where hydraulic fluid is likely present and a shrink chamber to shrink the landing gear. Moreover, the shrink pump and unshrink valve may be part of a strut shrink system.

Abstract: The present disclosure describes lug clusters for composite tubes and methods for making such lug clusters. Lug clusters of the present disclosure may include a first side, a second side, and a saddle. The saddle may be placed in adjacent contact with a tube and a filament may be wound around the lug cluster and tube. The wound lug cluster and tube may be resin transfer molded. Machining may follow to remove material and finalize the shape of the lug cluster and/or tube. Thus, a lug cluster may be attached to a composite tube.
