Abstract

Le présent docuement concerne un ensemble annulaire pour turbine de turbomachine, en particulier d’aéronef, ledit ensemble annulaire s’étendant autour d’un axe longitudinal X et comprenant :- un distributeur (20);- une roue à aubes (4) agencée en aval du distributeur (20) ;- ladite roue à aubes (4) étant entourée par un anneau sectorisé circonférentiellement et porté par le carter (16) externe et formé d’une couronne (18) et d’un déflecteur (20);caractérisé en ce que chaque secteur de déflecteur d’au moins un secteur d’anneau est engagé pour partie dans un logement du secteur de couronne dudit secteur d’anneau et en ce que le secteur de déflecteur et le secteur de couronne coopère par liaison de forme pour le maintien statique du secteur de déflecteur avec le secteur de couronne. Figure à publier avec l’abrégé : Figure 7This document relates to an annular assembly for a turbomachine turbine, in particular an aircraft turbine, said annular assembly extending around a longitudinal axis X and comprising:- a distributor (20);- a blade wheel (4) arranged downstream of the distributor (20); - said blade wheel (4) being surrounded by a circumferentially sectorized ring and carried by the outer casing (16) and formed of a crown (18) and a deflector (20); characterized in that each deflector sector of at least one ring sector is partly engaged in a housing of the crown sector of said ring sector and in that the deflector sector and the crown sector cooperate by linking form for the static maintenance of the deflector sector with the crown sector. Figure to be published with abstract: Figure 7
