본 개시내용에 따른 항공기 착륙 장치 구조물은 접개 작동기 및 수축 메커니즘을 포함한다. 접개 작동기는 수축 메커니즘을 통해 항공기 착륙 장치 구조물의 스트럿 조립체를 확장된 구성과 접힌 구성 사이에서 전환시킴으로써, 스트럿 조립체의 전체 세로 길이를 감소시키도록 구성된다. 접개 작동기는 또한 접개 메커니즘을 통해, 비행 중 항공기의 격납 영역으로 항공기 착륙 장치 구조물을 접어 넣도록 구성된다. 일부 예들에서, 접개 메커니즘은 이를테면, 접개 메커니즘과 수축 메커니즘을 결합하는 구동 링크를 통해 수축 메커니즘을 작동시키면서, 동시에 접힘 축을 중심으로 회전하여 항공기 착륙 장치 구조물을 접는 워킹 빔이다. 일부 예들에서, 수축 메커니즘은 접개 메커니즘에 기계적으로 종속된다. 수축 메커니즘은 일부 예들에서, 잠금 링크 조립체이다.

    An aircraft landing gear structure (18, 152) according to the present disclosure includes a retract actuator (32) and a shrink mechanism (22). The retract actuator (32) is configured to transition a strut assembly (100, 154) of the aircraft landing gear structure (18, 152) between an extended configuration (74) and a retracted configuration (72) via the shrink mechanism (22), thereby reducing the overall longitudinal length of the strut assembly. The retract actuator (32) is also configured to retract the aircraft landing gear into a stowage area of the aircraft during flight, via a retraction mechanism. In some examples, the retraction mechanism is a walking beam that rotates about a retraction axis to retract the aircraft landing gear structure, while simultaneously actuating the shrink mechanism (22), such as via a drive link coupling the retraction mechanism (32) and the shrink mechanism (22). In some examples, the shrink mechanism (22) is mechanically slaved to the retraction mechanism. The shrink mechanism (22) is a locking link assembly in some examples.
