Abstract

L'invention concerne un dispositif de freinage (74) d'une soufflante de turbomachine d'aéronef, ladite turbomachine comportant un moteur à turbine à gaz accouplé à ladite soufflante par l'intermédiaire d'un réducteur, caractérisé en ce qu'il comporte : - un arbre (24) solidaire en rotation de ladite soufflante, - un moyeu (76), monté coaxialement audit arbre (24) et mobile axialement et en rotation par rapport audit arbre (24), - un premier dispositif (78) de blocage centripète de l'arbre (24), configuré pour lier ledit arbre (24) audit moyeu (76) dès lors qu'un régime de rotation dudit arbre (24) est inférieur à un seuil de régime déterminé, - un deuxième dispositif de freinage du moyeu (76) par rapport à un carter (82) de ladite turbomachine, configuré pour lier ledit moyeu (76) audit carter (82) dès lors que le moteur à turbine à gaz (13) est arrêté.
