<p>The airfoil comprises a leading edge, a trailing edge spaced from the leading edge and an upper surface extending from the leading edge to the trailing edge. A lower surface extends from the leading edge to the trailing edge. The airfoil has a cross-sectional shape characterized by a thickness in a range from 24%-26%, a Reynolds number in a range from 1,000,000-1,800,000, and a maximum lift coefficient in a range from 1.4-1.6.</p> |
