ABSTRACT:
A blade is disclosed for use in a wind turbine, with the blade having a longitudinal axis for extending radially outwardly from a center of rotation of the blade on the wind turbine. The blade has a front side with a front surface for orienting in a windward direction and a rear side with a rear surface for orienting in a leeward direction. The blade has a profile taken in a plane oriented substantially perpendicular to the longitudinal axis of the blade. The profile of the blade has a leading edge and a trailing edge. The profile is characterized by a camber ratio, and the camber ratio of the profile is greater than or equal to approximately 4%.
