Abstract
A wind turbine blade (20B-C) with a rounded trailing edge (42A-E) and an elongated tab (44A-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.
