Abstract

L'invention concerne un ensemble de nacelle (800,1100,1300,1500,2000,2100) pour un moteur à double flux (10,802) qui comprend une portion de nacelle avant (921,1121,1321,1501,2108) comportant un bord arrière (920,1124,1320) et définissant un conduit de dérivation (24,906,1116,1306,1509,2112) qui transporte un écoulement d'air de dilution du moteur à double flux, un manchon translatable (902,1105,1302,1504,2102) qui peut être translaté à l'arrière de la portion de nacelle avant et un profil aérodynamique de tuyère de soufflante à section variable (VAFN) (50,904,1106,1304,1506,2106) qui est mobile entre une position rentrée, une position d'écoulement de VAFN, et une position d'inversion de poussée. Des volets obturateurs (912,1108,1312,1508,2118) pour la position de poussée sont intégrés dans le profil aérodynamique de VAFN.
