Abstract

Système de propulsion d’aéronef à ingestion de couche limite La présente invention concerne un système de propulsion d’aéronef à ingestion de couche limite (10) comportant au moins un propulseur à soufflante (12) accroché à une partie de structure arrière de l’aéronef et alimenté au travers d’un réducteur (14) par un générateur de gaz (16), le propulseur à soufflante comportant une pluralité d’aubes mobiles (120) montées sur un rotor de soufflante (122) tournant dans un carter de soufflante (124) et le rotor de soufflante est relié à un arbre d’entrainement du réducteur (140) par une première liaison souple (18) permettant des déplacements différentiels par rapport au générateur de gaz. Figure pour l’abrégé : Fig. 1.
