Abstract: A wing arrangement for an aircraft, comprising a wing having a base section and a tip section pivotably connected to base section such that the tip section is pivotable about a pivot axis between a deployed position and a stowed position. The wing arrangement also comprises a latching arrangement which includes an engagement portion, a latching actuator selectively movable between a first actuator position and a second actuator position, an elastically deformable structure, and a latching element. When the tip section is pivoted from the stowed or deployed position into an engagement position, the elastically deformable structure is initially deformed, and as the tip section pivots further into the deployed or stowed position, the elastic deformation of the elastically deformable structure decreases.

Abstract: A drive system for an aircraft landing gear is described. The drive system includes a drive pinion, a drive shaft arranged to rotate the drive pinion about a drive axis, and a casing which rotatably supports the drive shaft. The drive pinion is rotatably supported on the casing by a self-aligning bearing. The drive pinion is coupled to the drive shaft by a flexible coupling adapted to transfer torque between the drive pinion and the drive shaft and to permit tilting of the drive pinion relative to the drive axis.

Abstract: An aircraft include a landing gear is disclosed. The landing gear comprises a main strut and an inboard stay assembly connected to the aircraft fuselage such that landing gear loads can be transferred from the inboard stay assembly into the fuselage. The landing gear also comprises a sidestay connected to the wing such that landing gear loads can be transferred from the sidestay into the wing and a link assembly connected to the aircraft such that landing gear loads can be transferred via the link assembly into the aircraft. The landing gear is arranged such that, in use, when the landing gear is extended, substantially all the landing gear loads are transferred from the landing gear to the aircraft via one or more of the inboard stay assembly, the sidestay and the link assembly.

Abstract: A system for indicating the pressure in an aircraft landing gear shock absorber is provided, the system comprising a source of collimated light and a target, the source of collimated light being attached to the aircraft, and being operable to emit light onto the target; the position of the point of incidence of the light emitted from the source of collimated light on the target being indicative of the pressure in the aircraft landing gear shock absorber. A kit for making such a system and a method of indicating the pressure in an aircraft landing gear are also provided.

Abstract: An aircraft landing gear comprising a fibre optic load sensor for monitoring load in a component of the landing gear, such as an axle. The fibre optic cable is mounted on an inner surface of the component of the landing gear. Typically the fibre optic load sensor comprises one or more Bragg Grating sensors.

Abstract: An aircraft landing gear door assembly includes a plurality of doors (1 to 4) 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 (1) and second (2) doors arranged such that, when the landing gear is deployed, the second door (2) is obstructed from moving between its open and closed positions while the first door (1) is free to move between its open and closed positions. After the landing gear is deployed the first door (1) is closed.

Abstract: An aircraft landing gear door assembly has a plurality of doors. The doors include a first door (1) mounted for rotational movement between closed and open positions about a first generally longitudinal axis (11) and a transverse door (3) mounted for rotational movement between closed and open positions about a generally horizontal axis (13) that is transverse to the longitudinal axis (11). The provision of the transverse door (3) can allow the length of the first door (1) to be reduced from that which would otherwise be required to allow passage of the landing gear.
