Abstract
L'invention concerne un secteur angulaire (34a) de couronne d'aubages fixes de turbomachine, notamment de redresseur ou de distributeur, ledit secteur (34a) s'étendant suivant un angle déterminé autour d'un axe de la couronne d'aubages fixes et comportant, par rapport à l'axe de ladite couronne d'aubages fixes, une plateforme radialement extérieure (38a), une plateforme radialement intérieure (40a), au moins deux aubes (42a) qui s'étendent entre lesdites plateformes (38a, 40a), et au moins un bloc de matériau abradable en nid d'abeilles (44a) qui s'étend intérieurement à la plateforme intérieure (38a) entre des extrémités transversales du secteur (34a), caractérisé en ce que le bloc (44a) de matériau abradable comporte au moins une paroi (52a) d'extrémité transversale qui est conformée selon un profil denté (54a1, 54a2) comportant au moins une dent (56a1, 56a2) d'orientation radiale (R) s'étendant suivant toute une épaisseur radiale dudit bloc (44a).
