ABSTRACT OF THE DISCLOSURE An airfoil having improved aerodynamic charac- teristics incorporates a leading edge (13) and a trailing edge (14) longitudinally displaced therefrom. A continuous lower surface (21), defining the lower camber of the air- foil, extends from the leading edge (13) to the trailing edge (14). The upper surface of the airfoil incorporates a first upper surface (22) extending rearwardly from the loading edge (13) and terminating in an offset (20), and at least a second upper surface (23) extending rearwardly therefrom. The first upper surface (22) defines a first upper camber portion of the airfoil and the second upper surface (23) defines a second upper camber portion thereof.
