Abstract

TRAPPE DE LOGEMENT DE TRAIN D’ATTERRISSAGE D’AÉRONEF La présente invention concerne une trappe de logement de train d’atterrissage d’aéronef (140) comprenant un mécanisme d’attache approprié pour la fixation de manière pivotante de la trappe à un aéronef, et un premier côté (141) prévu pour être orienté vers l’intérieur relativement à un logement de train d’atterrissage d’aéronef lorsque la trappe est fermée et être orienté vers un côté d’une jambe principale (110) d’un train d’atterrissage lorsque la trappe est ouverte et le train d’atterrissage est déployé. Le premier côté comprend un profil incurvé. Lors de l’utilisation, l’écoulement d’air passant le long du profil incurvé est modifié par le profil incurvé. L’invention concerne également un système de train d’atterrissage d’aéronef, un aéronef, des procédés de manœuvre d’un aéronef et un procédé de réduction de bruit. Figure accompagnant l’abrégé : Figure 3AIRCRAFT LANDING GEAR HOUSING DOOR The present invention relates to an aircraft landing gear housing door (140) comprising an attachment mechanism suitable for pivotally attaching the door to an aircraft, and a first side (141) intended to face inwardly relative to an aircraft landing gear housing when the door is closed and to face one side of a main leg (110) of a landing gear landing gear when the hatch is open and the landing gear is deployed. The first side includes a curved profile. In use, the airflow passing along the curved profile is modified by the curved profile. The invention also relates to an aircraft landing gear system, an aircraft, methods of maneuvering an aircraft, and a method of noise reduction. Figure accompanying the abstract: Figure 3
