Abstract

L’invention concerne un ensemble comportant au moins un premier secteur (21) d’anneau (17) de turbine (7) et un second secteur (21) d’anneau (17) de turbine (7), les deux secteurs (21) étant disposés de façon adjacente l’un par rapport à l’autre, chaque secteur (21) s’étendant sur une portion angulaire autour d’un axe X, chaque secteur (21) comportant une partie radialement externe (22) comprenant des moyens de fixation aptes à permettre la fixation du secteur (21) à un carter de turbine et une partie radialement interne (23) comportant un matériau abradable destiné à coopérer avec des léchettes ou des sommets d’aubes mobiles de la turbine (7), la partie radialement externe (22) comportant une première extrémité circonférentielle comportant une première fente (25a) et une seconde extrémité circonférentielle comportant une seconde fente (25b).The invention relates to an assembly comprising at least a first sector (21) of the ring (17) of the turbine (7) and a second sector (21) of the ring (17) of the turbine (7), the two sectors (21 ) being arranged adjacent to each other, each sector (21) extending over an angular portion around an axis X, each sector (21) comprising a radially outer part (22) comprising fixing means capable of allowing the fixing of the sector (21) to a turbine casing and a radially internal part (23) comprising an abradable material intended to cooperate with the wipers or the tips of the moving blades of the turbine (7), the radially outer portion (22) having a first circumferential end having a first slot (25a) and a second circumferential end having a second slot (25b).
