Abstract

L’invention concerne une aube de compresseur de turbomachine, dont une épaisseur (EP) est définie dans la section d’aube par la distance entre un premier point de l’intrados et un deuxième point de l’extrados sur un premier segment perpendiculaire à la corde (AF), l’épaisseur (EP) suivant une courbe (CC) convexe d’épaisseur en fonction du pourcentage (PAF) de corde, la courbe (CC) passant par une épaisseur maximale (Emax) pour une valeur déterminée (XEmax) du pourcentage (PAF), caractérisée en ce que la courbe (CC) d’épaisseur passe par un point intermédiaire (I) de bombement amont, défini par le fait que : le pourcentage (IA) pris au point intermédiaire (I) est compris entre 5 % et 25 % et est inférieur à la valeur déterminée (XEmax), l’épaisseur (EPIA) prise au point intermédiaire (I) est comprise entre 75 % et 85 % de l’épaisseur maximale (Emax).
