Abstract

L'invention concerne une plateforme (18) de soufflante (12) de turbomachine (10), qui est destinée à être montée sur un moyeu (14) de la soufflante (12) entre deux aubes (16) adjacentes, la plateforme (18) comportant une paroi principale (20) qui est de forme cintrée selon la direction longitudinale en ayant des bords (24, 26) courbés, un raidisseur (34) qui est monté sur une face interne (36) de la paroi principale (20), caractérisée en ce que le raidisseur (34) comporte au moins deux tronçons (38) rectilignes qui sont inclinés l'un par rapport à l'autre et inclinés par rapport à la direction principale longitudinale, les parois d’extrémité transversales (44, 46) de chacun desdits tronçons (38) ayant leurs tranches externes situées à l’opposé de la paroi principale (20) qui sont libres de manière que la section du raidisseur soit ouverte à l’opposé de la paroi principale (20). Figure pour l’abrégé : Figure 3The invention relates to a platform (18) for a fan (12) of a turbomachine (10), which is intended to be mounted on a hub (14) of the fan (12) between two adjacent blades (16), the platform (18 ) comprising a main wall (20) which is of curved shape in the longitudinal direction having curved edges (24, 26), a stiffener (34) which is mounted on an internal face (36) of the main wall (20) , characterized in that the stiffener (34) comprises at least two rectilinear sections (38) which are inclined relative to each other and inclined relative to the main longitudinal direction, the transverse end walls (44, 46) of each of said sections (38) having their outer edges located opposite the main wall (20) which are free so that the section of the stiffener is open opposite the main wall (20).
