An aircraft landing gear assembly comprises a landing gear () arranged to be moveable between a stowed position and a deployed position. The assembly includes a removably mounted cover plate () that covers a void () defined by a part of the landing gear assembly. The plate () may have a substantially constant thickness, one or more fixing elements () on one side only of the plate, and a sealing element () that extends around substantially the entire perimeter () of the plate ().

Landing gear with noise reduction apparatus

An aircraft noise reduction apparatus includes an aircraft landing gear assembly and a noise reduction fairing. The landing gear assembly includes a landing geararranged to be moveable between a stowed position and a fully deployed position. The noise reduction fairingmay include a wrap-around fairing which, when the landing gearis in its fully deployed position, wraps around the landing gearand extends along the majority of the length of a landing gear leg. A landing gear bay door assemblyincluding at least one door may also be provided. The fairingmay have a recessfor accommodating one of landing gear bay doors when the dooris in its fully open position.

Landing gear with noise reduction fairing

An aircraft landing gear is described including a noise-reducing means. In one embodiment there is a noise-reducing element that includes an air-deflecting surface, in the form of a fairing, and a perforated airflow-reducing region. In use, some air passes through the perforations, while other air is deflected by the fairing away from a noise-generating region of the landing gear. Noise caused by the passing of the landing gear through the air is therefore reduced. In another embodiment a noise-reducing layer in the form of a mesh is supported by a skeleton structure.

Landing gear

An aircraft landing gear () includes a torque link set () comprising a first fairing () rotatably connected at a first end () to a first end () of a second fairing (). The fairings (), () may be arranged to act as first and second torque links. The fairings may be in the form of noise reduction fairings.

Torque link set

The invention relates to aircraft noise reduction apparatus, in particular, but not exclusively, to noise reduction apparatus on an aircraft landing gear. The aircraft noise reduction apparatus comprises a noise reduction attachment for a landing gear of an aircraft. The noise reduction apparatus is movable between a first position in which it deflects air away from a noise inducing component of the landing gear and a second position in which it allows access to the noise inducing component. The movement of the noise reduction attachment between the first and second positions is actuated by a part of the landing gear.

Aircraft noise reduction apparatus

An aircraft landing gearincludes a folding side stay, wherein the folding side stay includes an integral locking mechanism and does not require the landing gear to include a lock stay. The lack of a lock stay reduces the airframe noise created by the aircraft, which is particularly significant when the aircraft is landing. The aircraft landing gearis movable between an stowed and deployed position. The folding side staycomprises a first section and a second section foldable relative to the first section. The integral locking mechanismis arranged to lock the first section and second section of the folding side stay into position when the landing gear is in the deployed position.
