Abstract

L’invention concerne une aube (1) d’une partie tournante d’une turbomachine, ladite aube (1) comprenant une surface aérodynamique (2), ladite surface aérodynamique (2) comprenant une direction principale d’extension, et une hauteur (h) amont, ladite aube (1) comprenant : - une pale (8) et un bord d’attaque (4), - un bouclier (10) structurel rapporté et fixé sur le bord d’attaque (4), une portion supérieure (1a) du bouclier (10) en un premier matériau métallique et s’étendant sur une partie seulement de la hauteur (h) de ladite surface aérodynamique (2) depuis une partie adjacente à la tête de l’aube (1), l’aube (1) étant caractérisée en ce que la portion supérieure (1a) du bouclier (10) comporte un noyau interne (121) qui s’étend suivant la direction principale d’extension dans la portion supérieure (1a), ledit noyau interne (121) étant en un second matériau métallique d’une densité supérieure à la densité du premier matériau métallique.
