Abstract
An aircraft landing gear door assembly includes a plurality of doors moveable between open positions, in which landing gear can be deployed through an aperture, and closed positions, in which the doors are closed across the aperture. The plurality of doors includes first and second doors arranged such that, when the landing gear is deployed, the second door is obstructed from moving between its open and closed positions while the first door is free to move between its open and closed positions. After the landing gear is deployed the first door is closed.

An aircraft landing gear door assembly comprising a plurality of doors moveable between open positions, in which a landing gear can be deployed through an aperture, and closed positions, in which the doors are closed across the aperture, the plurality of doors comprising a first door and a second door, wherein
- during at least part of said movement of the plurality of doors, the movement of at least the first door of the plurality of doors is independent of the movement of the landing gear,
- the first and second doors are so arranged that they are, when installed on an aircraft, configurable in such a way that movement of one of the first and second doors for at least a part of the way between the open and closed positions causes movement of the other of the first and second doors, and
- the first and second doors are arranged such that, when the landing gear is deployed, the second door is obstructed from moving between its open and closed positions while the first door is free to move between its open and closed positions.
An aircraft landing gear door assembly comprising a plurality of doors moveable between open positions, in which a landing gear can be deployed through an aperture, and closed positions, in which the doors are closed across the aperture, the plurality of doors comprising a first door, a second door, a third door and a fourth door, wherein
- the first and second doors are so arranged that they are, when installed on an aircraft, configurable in such a way that movement of one of the first and second doors for at least a part of the way between the open and closed positions causes movement of the other of the first and second doors,
- the first and second doors are arranged such that, when the landing gear is deployed, the second door is obstructed from moving between its open and closed positions while the first door is free to move between its open and closed positions,
- the third and fourth doors are so arranged that they are, when installed on an aircraft, configurable in such a way that movement of one of the third and fourth doors for at least a part of the way between the open and closed positions causes movement of the other of the third and fourth doors,
- the third and fourth doors are arranged such that, when the landing gear is deployed, the fourth door is obstructed from moving between its open and closed positions while the third door is free to move between its open and closed positions,
- the first and third doors defining a first pair of doors on opposite sides of the aperture through which the landing gear is deployed,
- the second and fourth doors defining a second pair of doors on opposite sides of the aperture through which the landing gear is deployed.
