Abstract

Secteur d’un d istributeur et distributeur d’une turbine d’une turbomachine d’aéronef La présente invention concerne un distributeur (1) d’une turbine (2) d’une turbomachine d’aéronef comprenant une pièce d’étanchéité (6) d’un seul tenant munie d’une partie lamellaire (61) agencée pour être interposée dans un espace séparant une portion (31, 41) d’une plateforme extérieure ou intérieure de distributeur (3, 4) et un élément de la turbomachine adjacent au distributeur (1), et ce pour assurer une étanchéité fluidique de part et d’autre de cet espace. Cette pièce d’étanchéité (6) comprend aussi des parties de crochetage (62) munies d’une terminaison libre (63) courbée entourant une excroissance (32) de la portion (31, 41), et maintenus en position par des moyens (7) de fixation comprenant au moins un pion et/ou rivet (71). Figure pour l’abrégé : Figure 2Sector of a distributor and distributor of a turbine of an aircraft turbomachine The present invention relates to a distributor (1) of a turbine (2) of an aircraft turbomachine comprising a sealing part (6 ) in one piece provided with a lamellar part (61) arranged to be interposed in a space separating a portion (31, 41) of an outer or inner platform of a distributor (3, 4) and an element of the turbomachine adjacent to the distributor (1), in order to ensure fluid tightness on either side of this space. This sealing part (6) also comprises hooking parts (62) provided with a free curved end (63) surrounding a protuberance (32) of the portion (31, 41), and held in position by means ( 7) fixing comprising at least one pin and / or rivet (71).
