Abstract

Turbopropulseur hybride amélioré pour aéronef Turbopropulseur (100) hybride pour aéronef, comprenant un générateur de gaz (12) porté par un arbre de générateur (14), une turbine libre (11) portée par un arbre de turbine (13) et entraînée en rotation par un flux de gaz généré par le générateur de gaz (12), l’arbre de turbine (13) étant en prise avec un rotor principal (60) via une boîte de transmission (50) comprenant une première roue libre (51) orientée de telle sorte que le rotor principal (60) ne peut pas entraîner la turbine libre (11), une machine électrique réversible (30) en prise avec le rotor principal via la boîte de transmission (50) pour entrainer le rotor principal (60) lors d’un fonctionnement électrique ou hybride, le turbopropulseur comprenant une unique pompe à huile (40) en prise avec la boîte de transmission (50) pour être entrainée sélectivement par l’arbre de turbine (13) ou par la machine électrique (30) selon le mode de fonctionnement. Figure pour l’abrégé : Fig. 4.
