Abstract

Dispositif (10) de blocage en rotation d’une soufflante (12) carénée de turbomachine (14), cette soufflante étant solidaire en rotation d’un cône d’entrée (16) et étant entourée par un carter de soufflante (18), le dispositif étant configuré pour être logé à l’intérieur du carter, lorsque la turbomachine est à l’arrêt, et à être démonté et retiré de la turbomachine avant son fonctionnement, le dispositif comportant : - une coiffe (24) configurée pour prendre appui sur le cône d’entrée, et - au moins une branche (25) reliée à la coiffe et configurée pour prendre appui sur une surface interne (18c) du carter, le dispositif étant en outre configuré pour que les forces d’appui générées par la coiffe et la branche respectivement sur le cône d’entrée et le carter, soient suffisantes pour éviter une rotation libre de la soufflante par effet « windmilling ». Figure pour l'abrégé : 4
