    摘要： A landing gear actuation system is disclosed herein. The landing gear actuation system includes an attachment point (216) integral to a movable member, a flexible pull member (220) having a first end coupled to the attachment point (216), and a motor (218) configured to move the flexible pull member (220), wherein the movement of the flexible pull member (220) moves the attachment point (216) and the movable member.

    摘要： An aircraft assembly (14) comprising: a first part (18a); a second part (20b), the second part being movably mounted with respect to the first part; an electro-hydraulic actuator (42) coupled between the second part and a first anchor point (18a), the actuator comprising a cylinder defining a bore and a piston and rod assembly slidably mounted within the bore and an active chamber within which an increase in fluid pressure causes the actuator to change during a first phase between first and second extension states to move the second part relative to the first part. The electro-hydraulic actuator further comprises a hydraulic fluid supply circuit comprising a piezo-electric pump operable to supply pressurised fluid to the active chamber to change the actuator between first and second extension states.

    摘要： A landing gear is disclosed having a main strut being connected to a first attachment point located on the aircraft. The landing gear includes an inboard sidestay and outboard sidestays. The inboard sidestay has a first end connected to the main strut for movement along the main strut and is connected at a second end to a second attachment point located on the aircraft. The outboard sidestay has a first end connected to the main strut for movement along the main strut and is connected at a second end to a third attachment point located on the aircraft. When the landing gear is in a deployed configuration, the connection between the first end of each of the inboard and outboard sidestays and the main strut allows for movement of each first end along at least a portion of the length of the main strut.
