Abstract

SYSTÈME DE TRAIN D’ATTERRISSAGE D’AÉRONEF La présente invention concerne un système de train d’atterrissage d’aéronef (100) comprenant une trappe de train d’atterrissage (140) et une jambe de train d’atterrissage (110), la trappe et la jambe de train d’atterrissage comportant des côtés intérieurs placés en regard l’un de l’autre. Le système comprend en outre un élément de blocage d’écoulement d’air (150) attaché au côté intérieur de la trappe/la jambe de train d’atterrissage, s’étendant le long d’une ligne entre un emplacement sur le côté intérieur de la jambe de train d’atterrissage et un emplacement sur le côté intérieur de la trappe de train d’atterrissage. Lors de l’utilisation, un écoulement d’air entre le côté intérieur de la jambe de train d’atterrissage et le côté intérieur de la trappe est bloqué. L’invention concerne également un aéronef, des procédés de manœuvre d’un aéronef et des procédés de réduction de bruit. Figure accompagnant l’abrégé : Figure 1bAIRCRAFT LANDING GEAR SYSTEM The present invention relates to an aircraft landing gear system (100) comprising a landing gear door (140) and a landing gear leg (110), the hatch and the landing gear leg having interior sides placed facing each other. The system further includes an airflow blocking member (150) attached to the inboard side of the door/landing gear leg, extending along a line between a location on the inboard side of the landing gear leg and a location on the inboard side of the landing gear door. When in use, air flow between the inboard side of the landing gear leg and the inboard side of the hatch is blocked. The invention also relates to an aircraft, methods of maneuvering an aircraft, and methods of reducing noise. Figure accompanying the abstract: Figure 1b
