Abstract
A blade for the use in the generation of power has a leading edge and a trailing edge. A first shell portion of the blade extends from the leading edge to the trailing edge. A second shell portion of the blade also extends from the leading edge to the trailing edge. A root portion of the blade is positioned proximate the wind turbine and a tip portion which extends from the root portion away from the wind turbine. A trailing edge insert is positioned between the first shell portion and the second shell portion proximate the root portion. The trailing edge insert has a surface which extends between and separates the first shell portion from the second shell portion at the trailing edge, such that the insert provides a high lift profile for increased blade efficiency.
