Abstract

La présente divulgation concerne une ébauche d’aube de turbomachine obtenue par coulée de métal, comprenant une première direction (Z) le long de laquelle sont formés successivement une pale (13), une plateforme (12) et un pied (11), la plateforme (12) s’étendant selon une deuxième direction (X) sensiblement perpendiculaire à la première direction (Z), la pale (13) comprenant une face d’intrados (14) et une face d’extrados (15) reliées l’une à l’autre par un bord de fuite (16) et un bord d’attaque (17), le pied comprenant des surfaces de retenues (23, 24) selon la première direction (Z) de l’aube en rotation destinées à coopérer avec des surfaces correspondantes d’un disque de turbomachine, l’ébauche d’aube (100) étant remarquable en ce qu’elle comprend au moins un voile (200) s’étendant selon une troisième direction (Y) sensiblement perpendiculaire aux première et deuxième directions (Z,X), ce voile reliant une surface de retenue (25) selon la première direction à la plateforme.
