Abstract
An air foil includes a leading edge, a trailing edge, a hub contour, and a tip contour, whereby the hub contour and tip contour extend between the leading and trailing edges to define a blade surface therebetween. A localized thick spot is disposed between the leading edge and the trailing edge and extends from a first point on the hub contour to a second point on the tip contour. The localized thick spot includes a generally sheared profile and is operable to provide the air foil with a desired strength while concurrently providing desired aerodynamic properties.
