Record 4 2008-04-22

English

Subject field(s)
  • Flight Controls (Aeroindustry)
  • Landing Gear (Aeroindustry)
CONT

The MLG [main landing gear] retracts inwards into the fuselage wheel well. Each MLG has two doors. The outboard door is rigidly attached at the strut. The inboard door operates by mechanical linkage to the strut and is held in up position by two uplock cylinders. This uplock is released when landing gear lever is placed in down position by hydraulic pressure, or by nitrogen pressure in emergency. The MLG is held, while airborne, in retracted position by hydraulic pressure in the actuator and by the inboard door mechanical uplock, if pressure drops. As the gear is extended, an internal lock in the actuator automatically locks it in fully extended positions.

French

Domaine(s)
  • Commandes de vol (Constructions aéronautiques)
  • Atterrisseur (Constructions aéronautiques)
CONT

La séquence d'extension/rétraction des trains est conditionnée par la position du levier de commande «rentrée/sortie» des trains et par la réponse des détecteurs de positions du train et des trappes. Elle commande successivement l'ouverture des trappes, le déverrouillage du train, l'extension du train, le verrouillage du train en position basse, puis la fermeture des trappes principales (et inversement lors de la rétraction).

Record 6 2008-01-21

English

Subject field(s)
  • Landing Gear (Aeroindustry)
DEF

A small cylindrical or conical wheel used to guide or to support a mobile mechanical part.

CONT

The roller installed on the outboard landing gear bellcrank was of a smaller diameter than the required part and was designed to be used as an uplock roller vice bellcrank roller. The smaller diameter of the roller reduced the required clearance in relation to the roller's location on the heel of the positioning cam. Repetitive landing loads transmitted through the drag brace were initially absorbed by the roller hitting the lip of the cam, until the lip of the cam was worn away.

French

Domaine(s)
  • Atterrisseur (Constructions aéronautiques)
DEF

Petite roue cylindrique ou conique servant de guidage ou d'appui à une pièce mécanique mobile.

CONT

Le diamètre du galet monté sur le guignol extérieur du train était inférieur à celui de la pièce requise, et ce galet avait été conçu pour être utilisé comme galet de verrouillage train rentré plutôt que comme galet de guignol. Le diamètre plus faible du galet a réduit l'espacement nécessaire par rapport à la position du galet sur le talon de la came de positionnement. Les charges répétitives à l'atterrissage transmises par la contrefiche ont initialement été absorbées par le galet qui a percuté le rebord de la came jusqu'à ce que ce dernier soit complètement usé.

The nose gear uplock release mechanism provides a mechanical means for upsetting the nose gear overcenter linkage and releasing the nose gear from the uplocked position when hydraulic pressure is not available to extend the gear. The uplock release mechanism consists of a cable, cable sector, shaft, return spring, and upset arm.

CONT

The uplock release mechanism and pressure can are installed on the pressure bulkhead above the nosegear strut. Part of the mechanism is installed inside the pressure can and is accessible through the floor panel under the rudder pedals in the forward part of the flight compartment. The external portion of the mechanism is accessible through the nosegear doors.
