Abstract

L'invention concerne une aube creuse pour moteur à turbine à gaz. La paroi de la partie profilée aérodynamique de l'aube comporte une surépaisseur creuse longitudinale 35 au voisinage de son bord d'attaque, jouant le rôle d'une entretoise creuse faisant corps avec ladite paroi et soulageant le bord d'attaque de certaines contraintes. L'invention s'applique à toutes aubes creuses de moteurs à turbine à gaz mais convient particulièrement aux aubes réfrigérées.
