Abstract
An aircraft landing gear structure includes a strut assembly configured to transition between a compressed configuration, an extended configuration, and a retracted configuration. The strut assembly has a compressed length, an extended length, and a retracted length, such that the compressed length and retracted length are less than the extended length. The strut assembly includes an upper tubular housing, an upper bulkhead configured to be translated between a lower position and an upper position, a lower tubular housing operatively coupled to the upper tubular housing, a lower bulkhead supported by the lower tubular housing, and a pressure chamber defined between the lower bulkhead and the upper bulkhead. A volume of strut liquid and a mass of strut gas are positioned within the pressure chamber. A method of retracting a strut assembly includes longitudinally translating an upper bulkhead within an upper tubular housing from a lower position to an upper position.
