Abstract
Est concerné un dispositif d'étanchéité d'une turbomachine présentant comprenant un carter externe auquel sont fixés des blocs de matière abradable définissant un revêtement (46) interne adapté à coopérer avec des léchettes d'aubes d'un rotor tournant autour d'un axe (X). Le revêtement (46) comprenant des alvéoles (52) polygonales, liées deux à deux par des scellements (54), axialement (axe X), à l'endroit de côtés respectifs (54,56) circonférentiels du polygone, adjacents et s'étendant le long l'un de l'autre. Un dit scellement (54) s'étend circonférentiellement, sur une longueur (L1) déterminée commune desdits côtés circonférentiels respectifs où il est situé, et, circonférentiellement, une dite alvéole présente une longueur (L2) supérieure à au moins 2 fois celle (L1) d'un dit scellement.
