A plain blank (10) is sized to produce an airfoil (10a, b, c) The blank is plastically formed to include a pocket (24a, b) blending smoothly in one side thereof. Leading and trailing edges (20, 22) of the airfoil are benched. And, filler (26) is placed into the pocket to effect an aerodynamic profile for the airfoil. <IMAGE> |
