Abstract: Various embodiments of an airfoil and machines with airfoils are disclosed. The airfoils include a thicker leading airfoil portion and a thinner trailing airfoil portion. In one embodiment, the leading airfoil portion is formed by bending a body of the airfoil back toward itself. In another embodiment, the leading airfoil portion has a solid geometry and includes two elliptic surfaces. To prevent detachment of airflow, the leading airfoil portion includes at least two arc portions or surfaces that act to direct the airflow down to the trailing airfoil portion in a manner that stabilizes vortexes that may form in the region of changing thickness.

Abstract: A golf club head for a driver is disclosed. The golf club head includes a face portion and a rearward end portion. An upward facing surface in a crown portion of the golf club head curves up towards the rearward end portion to keep airflow from separating from the crown portion. A downward facing surface on a sole portion of the golf club includes an airfoil that helps keep air stuck to the sole portion of the golf club head. The airfoil portion extends across a substantial entirety of the width of the golf club head.
