Abstract

Aéronef comportant une motorisation à l’arrière du fuselage et une structure d’accrochage de cette motorisation Dans un aéronef comportant un fuselage (12) et au moins un premier et un deuxième propulseurs (10A, 10B) disposés en pointe arrière du fuselage, de part et d’autre d’une dérive de l’aéronef, chaque propulseur comportant au moins un rotor de soufflante (16A, 16B) suivi d’un aubage redresseur (18A, 18B), l’ensemble étant entouré d’une nacelle comportant un carter de soufflante (20A, 20B) et un carter intermédiaire (22A, 22B) de l’aubage redresseur solidaires l’un de l’autre, chaque rotor de soufflante (16A, 16B) étant entrainé en rotation par l’énergie fournie par au moins un générateur de couple (24A, 24B) installé dans le fuselage, il est prévu que le premier et le deuxième propulseurs soient reliés par une structure d’accrochage articulée (28A, 28B) à une partie structurelle de dérive (14) de l’aéronef.
