The invention relates to a housing (16a) for a stator of a module of an aircraft turbine engine provided with a plurality of through-openings (22) respectively receiving a stator blade (4) and defining a skeleton (32) extending between a first end (25) for housing the trailing edge of the blade and a second end (27) for housing the leading edge (28) of the blade. According to the invention, a mechanical offloading slit formed through the housing is associated with one of the openings (22), facing, and at a distance from, the first end (25) of the opening according to the direction of the skeleton (32).
L'invention se rapporte à une virole (16a) pour stator de module de turbomoteur d'aéronef pourvue d'une pluralité d'ajours traversants (22) chacun destiné à recevoir une aube de stator (4), chaque ajour définissant un squelette (32) s'étendant entre une première extrémité (25) destinée à loger le bord de fuite (26) de l'aube et une seconde extrémité (27) destinée à loger le bord d'attaque (28) de l'aube. Selon l'invention, à au moins l'un des ajours (22) est associée une fente de déchargement mécanique (36) pratiquée traversante sur la virole, et agencée en regard et à distance de la première extrémité (25) de l'ajour selon la direction du squelette (32).
