    Abstract: A remote hydraulic system for an aircraft may provide hydraulic fluid to nose landing gear while being isolated from the main landing gear and other main hydraulic systems of the aircraft. A supply pressure accumulator may be configured to supply hydraulic fluid to a hydraulic load of the nose gear. A pressure sensor may be configured to detect a hydraulic pressure in the supply pressure accumulator. A pump may be in fluid communication with the supply pressure accumulator and configured to switch on in response to the hydraulic pressure below a threshold value. A return pressure accumulator may be configured to store the hydraulic fluid returning from the hydraulic load. The pump may drive fluid from the return pressure accumulator to the supply pressure accumulator.

    Abstract: A damper is provided for responding to relative movement of arms to which the damper is coupled. The damper includes a member, springs, a first housing and a second housing. The first housing includes a first body and first bellows affixed to the member and the first body by first joints to define a first interior. The second housing includes a second body and second bellows affixed to the member and the second body by second joints to define a second interior. The first and second interiors are configured to contain fluid charged therein and the member is configured to permit bi-directional flows of the fluid between the first and second interiors responsive to the relative movement of the arms and in opposition to an elasticity of the springs.

    Abstract: The landing gear systems, methods and apparatuses disclosed herein may comprise a shrink pump and a shrink valve that are capable of shrinking a landing gear by up to 40% of its available stroke, or more depending on the air spring configuration. 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 shrink valve may be part of a strut shrink system.
