Abstract
L'invention concerne un disque de rétention d'aubes (20) comportant, sur sa surface externe, une rainure annulaire périphérique (22) apte à recevoir une pluralité de pieds (29) d'aube de type attache marteau, ladite rainure annulaire périphérique (22) comportant une fenêtre de chargement (23) destinée à l'introduction des pieds (29) d'aube dans ladite rainure annulaire périphérique (22). Le disque de rétention (20) comporte en outre : - une couronne (25) recouvrant ladite rainure annulaire périphérique (22); - des moyens de centrage (24) de ladite couronne (25), lesdits moyens de centrage (24) et ladite couronne (25) formant une enceinte (28) d'alimentation en air du fond de ladite rainure annulaire périphérique (22) ; - au moins un orifice (31) débouchant dans ladite enceinte (28) d'alimentation en air, ledit orifice (31) étant destiné à l'introduction d'air de refroidissement dans ladite enceinte (28) d'alimentation en air. Le disque de rétention d'aubes trouve une application directe dans le domaine d'une turbine basse pression d'une turbomachine d'aéronef.
