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).
An aircraft landing gear and door assembly comprising a landing gear and a door, the door being moveable to an open position, in which an aperture is exposed, the landing gear being able to be deployed through said aperture, the door being moveable to a closed position, in which the door is closed across the aperture, wherein at least a part of the door is arranged for movement of a first type, in which the door moves between the closed position and the open position, wherein at least a portion of the same door is also arranged for movement of a second type, in which said at least a portion of the same door moves to a fairing position in which it acts as a fairing to reduce the noise caused by the landing gear or a part thereof when the landing gear is in its fully deployed position, and wherein the first type of movement is different from the second type of movement, said door is coupled to the aircraft using a coupling mechanism that includes first and second linkages so arranged that when the assembly is installed on an aircraft, during movement of the first type the door is coupled to the first linkage and decoupled from the second linkage and during movement of the second type the door is decoupled from the first linkage and coupled to the second linkage.
An aircraft landing gear and door assembly including a door movable to and from a closed position, in which the door is closed across an aperture, the aperture when open allowing a landing gear to be deployed through the aperture, wherein
A door assembly for an aircraft landing gear bay, the door assembly comprising a door moveable between a closed position and a fully open position, the fully open position defined as creating a gap within an aircraft landing gear bay sufficient for the extension of a landing gear, wherein
