Abstract

L'invention concerne une aube de turbomachine. L'aube comprend un pied (P). Le pied (P) est traversé par une cavité amont (16) et une cavité aval (18). La cavité amont (16) et la cavité aval (18) sont configurées pour collecter au niveau du pied (P) de l'air de refroidissement destiné à refroidir la pale. La base intérieure (40) du pied (P) comprend un premier étage (41) et un deuxième étage (42) décalé du premier étage (41) selon la direction d'envergure (EV) de l'aube. Le deuxième étage (42) est en aval du premier étage (41). La cavité amont (16) traverse au moins partiellement le premier étage (41). La cavité aval (18) traverse au moins partiellement le deuxième étage (42).
