Abstract

L'invention concerne un secteur angulaire de couronne d'aubage fixe de turbomachine (10), notamment de redresseur ou de distributeur, ledit secteur s'étendant suivant un angle déterminé autour d'un axe A de ladite couronne et comportant, par rapport audit axe A, une plateforme radialement extérieure, une plateforme radialement intérieure, au moins deux aubes qui s'étendent entre lesdites plateformes, et au moins un bloc de matériau abradable (44a) en nid d'abeilles qui s'étend intérieurement à la plateforme intérieure entre des extrémités transversales (52a) du secteur (34a) et qui comporte des alvéoles tubulaires (54a) orientées radialement, caractérisé en ce que le bloc de matériau abradable (44a) comporte au moins une paroi d'extrémité transversale (52a) au niveau de laquelle les toutes les alvéoles (54a) sont ouvertes par des ouvertures (56a1, 56a2) tournées du côté opposé audit secteur (34a).
