Abstract

AERONEF AVEC NACELLE MOBILE ET PROCEDE CORRESPONDANT L’invention concerne un procédé de mise en œuvre d’un aéronef (2) comprenant un fuselage (4), deux ailes (6) disposées respectivement de part et d’autre du fuselage (4), et deux groupes propulsifs (10) disposés respectivement en aval et à distance (H) de chaque aile (6), chacun des groupes propulsifs (10) comprenant une nacelle (12) accueillant au moins deux soufflantes (14) non coaxiales, ladite nacelle (12) comprenant une paroi supérieure (16) et une paroi inférieure (18), le procédé étant remarquable en ce qu’il comprend une phase de vol subsonique lors de laquelle la paroi inférieure (18) s’étend sensiblement dans le prolongement de l’aile (6), et une phase de vol transsonique lors de laquelle la paroi supérieure (16) s’étend sensiblement dans le prolongement de l’aile (6). L’invention porte également sur l’aéronef associé. (Figure à publier avec l'abrégé : Figure 5)AIRCRAFT WITH MOBILE NACELLE AND CORRESPONDING METHOD The invention relates to a method for implementing an aircraft (2) comprising a fuselage (4), two wings (6) arranged respectively on either side of the fuselage (4), and two propulsion groups (10) arranged respectively downstream and at a distance (H) from each wing (6), each of the propulsion groups (10) comprising a nacelle (12) accommodating at least two non-coaxial fans (14), said nacelle (12) comprising an upper wall (16) and a lower wall (18), the method being remarkable in that it comprises a subsonic flight phase during which the lower wall (18) extends substantially in the extension of the wing (6), and a transonic flight phase during which the upper wall (16) extends substantially in the extension of the wing (6). The invention also relates to the associated aircraft. (Figure to be published with the abstract: Figure 5)
