    摘要: A two-stage aircraft gear. The landing gear includes a cantilever landing gear (110) whose lower end is attached to a trailing arm (or articulated) landing gear (112). The cantilever gear is a collapsible piston­cylinder assembly (116, 114), and the trailing arm gear also has a shock absorber (143) connected between a fixed portion of the trailing arm gear (136) and the movable wheel support arm (138). When landing, the load imposed is first absorbed by the trailing arm landing gear (112). After the trailing arm gear has been fully compressed, the cantilever gear (110) begins to compress. The cantilever and trailing arm landing gear can be combined to provide the desired performance. The landing gear static position can be designed to be in the static load curve of the first component, allowing the aircraft to be stably supported and yet difficult to overturn.

    摘要: An aircraft landing gear assembly comprises a first landing gear element movably coupled relative to a second landing gear element to move between a first condition and a second condition. The aircraft landing gear assembly further comprises a fibre composite leaf spring formed from a plurality of composite layers and arranged between the first and second elements, the leaf spring being arranged to bend when the first element moves from the first condition to the second condition. The fibre composite leaf spring comprises a first region and a second region, wherein the number of composite layers in the first region is greater than the number of composite layers in the second region. The landing gear further comprises a mounting assembly arranged to engage the first region of the leaf spring to couple the leaf spring to the first landing gear element.
