CA 2633319

The present invention provides an airfoil for a first stage turbine blade having an external surface with first and second sides. The external surface extends spanwise between a hub and a tip and streamwise between a leading edge and a trailing edge of the airfoil. The external surface includes a contour substantially defined by Table 1 as listed in the specification.

L'invention concerne un profil aérodynamique pour une pale de turbine primaire, présentant une surface externe dotée de premier et deuxième côtés. La surface externe s'étend dans la direction radiale entre une base et une extrémité, et dans la direction méridienne entre un bord d'attaque et un bord de fuite du profil aérodynamique. La surface externe présente un contour sensiblement défini par le Tableau 1 figurant dans le mémoire descriptif.
