Shrinking shock strut system for retractable landing gear

摘要

A shrinking shock strut (11) system for an aircraft landing gear (10) having a retract actuator (17) that is moveable in length to deploy or retract the landing gear (10), that includes a shrink strut (11) and a transfer device. The shrink strut (11) may be compressed in length for stowage in the fuselage. The transfer device may be in closed fluid communication with the strut shrink (11) for transferring and receiving hydraulic fluid to and from the strut shrink (11). When actuated by an aircraft hydraulic system independent of any motion of the retract actuator (17), the transfer device may drive hydraulic fluid to the strut shrink thereby compressing or shrinking the shrink strut (11) to a partially compressed length.
