Abstract

TRAPPE DE LOGEMENT DE TRAIN D’ATTERRISSAGE D’AÉRONEF L’invention concerne une trappe de logement de train d’atterrissage d’aéronef (140) comprenant un premier côté de panneau orienté vers l’intérieur relativement au logement de train d’atterrissage lorsque la trappe est fermée et orienté vers un côté d’une jambe principale (110) d’un train d’atterrissage (100) déployé lorsque la trappe est ouverte, un second côté de panneau (141) opposé et un élément de guidage d’écoulement d’air (150). L’élément de guidage d’écoulement d’air est attaché au premier côté de panneau et s’étend à partir de celui-ci, et est attaché à un emplacement du premier côté de panneau qui est situé derrière la jambe principale. L’écoulement d’air (1001) est guidé par l’élément de guidage d’écoulement d’air de sorte qu’il s’éloigne du premier côté de panneau et passe derrière la jambe principale. 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 1aAIRCRAFT LANDING GEAR HOUSING DOOR An aircraft landing gear housing door (140) includes a first panel side facing inward relative to the landing gear housing when the hatch is closed and oriented towards one side of a main leg (110) of a landing gear (100) deployed when the hatch is open, a second opposite panel side (141) and a guide member of air flow (150). The airflow guide member is attached to and extends from the first panel side, and is attached to a location on the first panel side that is located behind the main leg. The airflow (1001) is guided by the airflow guide member so that it flows away from the first panel side and passes behind the main leg. 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 1a
