Abstract

Ensemble propulsif pour un arrière de fuselage d’un aéronef, comprenant : - une turbomachine (2) à double flux présentant un axe principal (X), la turbomachine comprenant un corps haute pression et un corps basse pression comprenant un arbre basse pression (11) monté mobile en rotation autour de l’axe principal, - une nacelle recevant la turbomachine (2), - un mât (14) de support de la turbomachine fixé à la turbomachine d’une part et destiné à être fixé à l’arrière de fuselage d’autre part, et - une machine électrique (15) comprenant au moins un stator (22) solidaire de la turbomachine, disposé extérieurement à la nacelle, d’un côté opposé au mât relativement à l’axe principal, et au moins un rotor (23) entraîné en rotation par l’arbre basse pression autour d’un axe de rotation (X’) formant un angle (β) inférieur ou égal à 15° avec l’axe principal (X).
