Title (EN) FIXED-WING AIRCRAFT WITH INCREASED STATIC STABILITY
(FR) AERONEF A VOILURE FIXE ET A STABILITE STATIQUE ACCRUE
Abstract:
(EN) The invention relates to an aircraft having at least one wing (5) including, at each end thereof, a fin (6) forming an angle of between 0° and 45° relative to the vertical. According to the invention, each fin (6) has a leading edge (7) that includes at least one slot (8) provided along said leading edge (7) and oriented so as to cause an air flow to flow via said leading edge (7) from an outer surface (6a) of the fin (6) to an inner surface (6b).
(FR) L'invention concerne un aéronef présentant au moins une aile (5) comprenant, à chacune de ses extrémités, une ailette (6) formant un angle compris entre 0° et 45° par rapport à la verticale. Selon l'invention, chaque ailette (6) présente un bord d'attaque (7) qui comprend au moins une fente (8) ménagée le long dudit bord d'attaque (7) et orientée pour faire circuler un flux d'air au travers dudit bord d'attaque (7) à partir d'une face externe (6a) de l'ailette (6) jusqu'à une face interne (6b).
