Abstract:
A wind turbine blade ( 20 B-C) with a rounded trailing edge ( 42 A-E) and an elongated tab ( 44 A-J) extending from the pressure side (PS) within the aft 10% of the local chord (C) and generally parallel to the trailing edge to increase lift. The tab may have a height (H) that is greatest on the radially inboard end to maximize lift, and lower on the outboard end to minimize drag. It may have a base with a length of at least 60% of its height.

Claim (Index 13):
A wind turbine blade comprising:\n a root, a tip, and a span there between; a cylindrical root portion extending radially outward from the root; a maximum chord position comprising a lifting airfoil cross sectional profile at a radial position outboard of the cylindrical root portion; a transition of airfoil profile shape over a spanwise transition length between the cylindrical root portion and the maximum chord position; a rounded trailing edge with a radius of curvature of at least 2% of a local chord length as seen in cross section over an inboard 30% of the blade span; and a tab extending from a pressure side of the wind turbine blade within an aft 10% of the local chord length over a portion of the blade from the maximum chord position to at least one transition length outward from the maximum chord position, wherein the radius of curvature is 50% of local chord length at the cylindrical root portion, and reduces to 3-5% of local chord length at one transition length outward from the maximum chord position.
