Abstract

L'invention concerne un noyau (10) utilisé pour la fabrication par fonderie à la cire perdue d'une aube de turbomachine, s'étendant selon une direction longitudinale (L) entre un pied (14) et une tête (12). La tête (12) du noyau (10) est conformé pour constituer une cavité en sommet d'aube et comprend un évidement (18) comportant une première face (26) sensiblement perpendiculaire à la direction longitudinale (L).The invention relates to a core (10) used for the production by lost wax casting of a turbine engine blade, extending in a longitudinal direction (L) between a foot (14) and a head (12). The head (12) of the core (10) is shaped to constitute a cavity at the top of the blade and comprises a recess (18) comprising a first face (26) substantially perpendicular to the longitudinal direction (L).
