An aircraft landing gear door assembly (1, 2, 3, 4, 5) includes a door
(1), which is moveable to an open position, in which an aperture (6) is
exposed, the landing gear (10) being able to be deployed through said
aperture (6), and moveable to a closed position, in which the door (1) is
closed across the aperture (6). The door (1) is arranged for rotational
movement of a first type, in which the door rotates about an axis that is
substantially parallel to the length of the aircraft, between the closed
position and the open position. The door (1) is also arranged for
movement of a second type, different from the first type, in which the
door (1) rotates, about an axis that is substantially transverse to the
length of the aircraft, to a position in which it acts as a fairing to
reduce the noise caused by the landing gear or a part thereof. In one
embodiment, the second type of movement is rotational movement about an
axis that is substantially parallel to the door when in the closed
position and the door (1) forms a ramp type fairing. In another
embodiment, the second type of movement is rotational movement about an
axis that is substantially transverse to the door when in the closed
position and the door (31) forms a V-shaped fairing (when viewed from
above) with an opposite door (33).
