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 1):
A wind turbine blade comprising:\n a cylindrical root portion; a maximum chord position comprising a lifting airfoil cross sectional profile; a transition region comprising a radial transition length between the root portion and the maximum chord position; a trailing edge that is rounded in cross section from the root portion to at least one transition length radially outward of the maximum chord position; and an elongated tab extending from a pressure side of the wind turbine blade over at least a portion thereof from the maximum chord position to said one transition length outward of the maximum chord position; wherein the tab is located within an aft 10% of the chord length of the blade, and wherein the tab comprises a height normal to the pressure side, and the height gradually changes from 3-6% of local chord length at an inboard end of the tab to 0.5%-2% of local chord length at an outboard end of the tab.
