An airfoil includes a leading edge, a trailing edge, a pressure side surface extending from the leading edge to the trailing edge, a suction side surface extending from the leading edge to the trailing edge and generally opposite the pressure side surface and a plurality of cooling holes. The cooling holes are positioned on the airfoil in accordance with X, Y and Z Cartesian coordinate values set forth in an accompanying Table. L'invention concerne une aube qui comprend un bord d'attaque, un bord de fuite, une surface côté pression s'étendant du bord d'attaque au bord de fuite, une surface côté aspiration s'étendant du bord d'attaque au bord de fuite et opposée généralement à la surface côté pression et une pluralité de trous de refroidissement. Les trous de refroidissement sont positionnés sur l'aube en fonction d'un ensemble de valeurs de coordonnées cartésiennes X, Y et Z présentées dans une table annexe.
