ABSTRACT:
A golf club head having an aerodynamic upper surface including a vertical airfoil and a cavity therein. The cavity includes a first planar surface sloping downwardly and rearwardly from behind the ball striking face, and an upstanding rear wall which acts as the front portion of the airfoil. A normal swing of the club head positions the airfoil at substantially right angles to the swing path creating an aerodynamic effect on the air flow to reduce drag and increase clubhead speed.
