Abstract

TURBOMACHINE COMPORTANT UNE STRUCTURE ET UNE STRUCTURE INTERNE D’UN CONDUIT D’EJECTION PRIMAIRE FIXEE A LADITE STRUCTURE L’invention concerne une turbomachine (200) avec une direction longitudinale X et comportant une structure (210) présentant une surface extérieure (212) et une paroi de fixation (216) disposée dans un plan normal à la direction longitudinale X, une structure interne (206) présentant une surface extérieure (214) alignée avec la surface extérieure (212) de la structure (210) pour constituer une surface intérieure d’un conduit d’éjection primaire (202), et une pluralité de boulons (218) qui fixent la structure interne (206) à la paroi de fixation (216). Pour chaque boulon (218), la surface extérieure (214) de la structure interne (206) comporte un évidement (150) ouvert vers l’extérieur de la structure interne (206), et délimité à l’avant par une plaque (220) et à l’intérieur par une paroi intérieure (222), où la plaque (220) est disposée dans un plan normal à la direction longitudinale X et en appui contre la paroi de fixation (216), où la plaque (220) présente une extrémité extérieure orientée vers l’extérieur de la structure interne (206) et une extrémité intérieure orientée vers l’intérieur de la structure interne (206), où la paroi intérieure (222) s’enfonce à l’intérieur de la structure interne (206) depuis la surface extérieure (214) de la structure interne (206) vers l’extrémité intérieure de la plaque (220), et où la plaque (220) et la paroi de fixation (216) présentent chacune un alésage pour le passage de la tige filetée du boulon (218). Fig. 3TURBOMACHINE COMPRISING A STRUCTURE AND AN INTERNAL STRUCTURE OF A PRIMARY EXHAUST DUCT FIXED TO SAID STRUCTURE The invention concerns a turbomachine (200) with a longitudinal direction X and comprising a structure (210) having an outer surface (212) and a attachment wall (216) disposed in a plane normal to the longitudinal direction X, an internal structure (206) having an exterior surface (214) aligned with the exterior surface (212) of the structure (210) to constitute an interior surface of a primary ejection duct (202), and a plurality of bolts (218) which secure the internal structure (206) to the attachment wall (216). For each bolt (218), the outer surface (214) of the internal structure (206) comprises a recess (150) open towards the outside of the internal structure (206), and delimited at the front by a plate (220 ) and inside by an inner wall (222), where the plate (220) is arranged in a plane normal to the longitudinal direction X and bearing against the fixing wall (216), where the plate (220) has an outward facing outer end of the internal structure (206) and an inward facing inner end of the internal structure (206), where the inner wall (222) sinks inside the internal structure (206) from the exterior surface (214) of the internal structure (206) towards the interior end of the plate (220), and where the plate (220) and the fixing wall (216) each have a bore for the passage of the threaded rod of the bolt (218).
