Abstract

L’invention a pour objet un distributeur (16) de turbine, comportant des secteurs aubagés (17) assemblés selon un agencement ayant une forme de révolution autour d’un axe longitudinal (AX), chaque secteur aubagé (17) comportant une tête et un pied (21) reliés l’un à l’autre par au moins une aube (22-25). Le distributeur comporte un l’élément annulaire d’étanchéité (18) entouré par les pieds (21) des secteurs aubagés (17), qui comporte une face radialement interne couverte d’un matériau abradable (19). Au moins trois liaisons linéaires annulaires (32) orientées radialement par rapport à l’axe longitudinal (AX), relient l’élément annulaire d’étanchéité (18) à un pied (21) de secteur aubagé (17). Figure pour l’abrégé : Figure 4.
