Abstract

Module de soufflante (10) pour une turbomachine d’aéronef, comportant : un disque de soufflante (18) portant des aubes (20) et des plateformes inter-aubes (22), une virole annulaire (14) et comportant un premier rebord annulaire aval (14b) à sa périphérie externe qui s’étend autour d’un bord axial amont de chacune des plateformes et prend appui radialement sur ces bords, et un cône d’entrée d’air (12) fixé sur la virole (14), caractérisé en ce que le cône (12) comprend un second rebord annulaire aval (12a) à sa périphérie externe qui recouvre le premier rebord (14b) et qui s’étend axialement jusqu’à une extrémité libre aval de ce premier rebord, en prenant appui radialement sur cette extrémité libre, de façon à ce que les premier et second rebords (12a, 14b) participent à la retenue radiale des bords (22a) des plateformes (22).
