The invention relates to an aircraft comprising three fuselages which are separated transversely from one another, namely a central fuselage (1) and two lateral fuselages (2, 2'). The aforementioned fuselages are interconnected by means of two positive bearing surfaces which are separated longitudinally from one another and which each comprise two fixed wings which extend between the central fuselage (1) and each lateral fuselage (2, 2'). According to the invention, the two fixed front wings (30, 30') and the two fixed central wings (40, 40') comprise leading edges (41, 41') which are symmetrically inclined at a positive sweep angle of at least 40·. Moreover, the surface area of each free space (12) between the trailing edge (32) of a fixed front wing (30) and the leading edge (41) of the central wing (40) therebehind is, at most, of the same order as the surface covered by said front wing (30). According to the invention, a triple-fuselage aircraft of this type can be used to improve transport safety and, from one base fuselage, to produce at least two families of aircraft with two or three engines.
L'invention a pour objet un avion comprenant trois fuselages écartés transversalement l'un de l'autre, respectivement un fuselage central (1) et deux fuselages latéraux (2, 2'), reliés entre eux par au moins deux surfaces portantes positives écartées longitudinalement l'une de l'autre et comportant chacune deux voilures fixes s'étendant entre le fuselage central (1) et chaque fuselage latéral (2, 2').Conformément à l'invention, les deux voilures fixes avant (30, 30') et les deux voilures fixes centrales (40, 40') présentent des bords d'attaque (41, 41') inclinés symétriquement d'un angle de flèche positive d'au moins 40~, et la surface de chaque espace libre (12) compris entre le bord de fuite (32) d'une voilure fixe avant (30) et le bord d'attaque (41) de la voilure centrale (40) qui la suit est, au plus, du même ordre que la surface couverte par ladite voilure avant (30).Un avion à trois fuselages de ce type permet, selon l'invention, d'améliorer la sûreté de transport et permet,à partir d'un fuselage de base, de réaliser au moins deux familles d'avion à deux ou trois moteurs.
