Abstract

L’invention concerne un carter (10a) de turbomachine comprenant une virole annulaire radialement interne une virole annulaire radialement externe (14a) reliées l’une à l’autre par au moins un bras creux (18a) de passage de servitudes comportant à une extrémité une embase (30a) de fixation à une première de la virole annulaire interne et de la virole externe (14a) qui comprend un orifice communiquant avec l’intérieur du bras, des moyens d’étanchéité (34) étant appliqués à la jonction de l’embase (30a) et de ladite première virole (14a), caractérisé en ce que lesdits moyens d’étanchéité (30a) comprennent une structure rigide (36) appliquée sur une face radialement interne de la première virole (14a) et sur une face extérieure dudit bras (18a), ladite structure rigide (36) étant intégralement recouverte par une couche (38) céramisante.
