Abstract

L'invention porte sur un ensemble propulsif d'aéronef comportant un premier moteur comportant une première tuyère (17) et un deuxième moteur comportant une deuxième tuyère (18), et une nacelle (1). La première tuyère (17) et la deuxième tuyère (18) ont chacune une section de sortie, définie par une paroi externe de la tuyère, dont une portion est sensiblement droite, et la portion droite de la section de sortie de la première tuyère (17) et la portion droite de la section de sortie de la deuxième tuyère (18) sont au contact l'une de l'autre ou forment une paroi commune audites tuyères (17,18) au niveau d'un plan médian (PM) de symétrie de l'ensemble propulsif. La grande proximité permise entre les moteurs permet de limiter l'espace entre le carénage de chaque moteur formé par la nacelle, et de limiter la trainée aérodynamique du groupe propulsif.
