Abstract

AUBE POUR ROUE DE TURBOMACHINE L’invention concerne une aube (1) d’une roue de turbomachine d’axe longitudinal X, l’aube (1) comprenant un pied (2) depuis lequel s’étend une pale (3) suivant un axe d’empilement, ledit pied (2) comprenant : un bulbe (7) destiné à s’engager dans une rainure d’un disque de rotor, et une échasse (8) s’étendant suivant un axe radial depuis le bulbe (6) et étant reliée au bulbe par un col (9), l’échasse (8) comprenant une paroi amont (18) et une paroi (19) aval opposées suivant l’axe longitudinal X et s’étendant suivant un axe transversal T. Selon l’invention, les parois amont et aval (18, 19) de l’échasse (8) présentent chacune au moins une portion de paroi épaissie (35) au moins localement au-dessus du col (9) en direction de la pale, suivant l’axe radial Z.
