Abstract

Turbomachine (10) d'aéronef, comportant un générateur de gaz (12) et une soufflante (14) située en amont du générateur de gaz et entourée par un carter de soufflante (16), le générateur de gaz comportant un corps haute pression (12b) et un corps basse pression (12a) qui est relié à un arbre de la soufflante (32), les corps haute et basse pression comportant des compresseurs (22, 20) entre lesquels est situé un carter intermédiaire (40) qui relie le générateur de gaz audit carter de soufflante, la turbomachine comportant en outre des moyens de découplage (60) configurés pour désolidariser l'arbre de soufflante du corps basse pression suite à une détection d'un évènement critique, caractérisée en ce que lesdits moyens de découplage comprennent des moyens fusibles (62) de fixation d'un stator du compresseur du corps basse pression au carter intermédiaire.
