Abstract

L’invention concerne un groupe propulseur d’aéronef comprenant un moteur électrique (5) présentant un rotor (8) et un stator (9) relié mécaniquement à une embase (10) apte à être montée à l’arrière du fuselage d’un aéronef (11), une soufflante (12) entraînée en rotation par le rotor (8), un ensemble d’aubes fixes (13) situé en aval de la soufflante (12) ; et une nacelle (14) comportant une enveloppe extérieure (15) et un carter de soufflante (16) enveloppant la soufflante (12) et l’ensemble d’aubes fixes (13). La nacelle (14) est reliée mécaniquement à l’embase (10) à travers l’ensemble d’aubes fixes (13). Cette configuration permet de former un circuit de refroidissement (19) permettant d’évacuer la chaleur produite par le moteur électrique (5) au niveau du stator (9) vers les aubes fixes (26) et la nacelle (14) où elle est dissipée. En outre cette chaleur peut être utilisée pour le dégivrage de la lèvre de nacelle (35). Figure pour l’abrégé : Figure 2
