Flatback insert for turbine blades

摘要

A blade (108) for use in the generation of power has a leading edge (201) and a trailing edge (203). A first shell portion (301) of the blade (108) extends from the leading edge (201) to the trailing edge (203). A second shell portion (302) of the blade (108) also extends from the leading edge (201) to the trailing edge (203). A root portion (209) of the blade (108) is positioned proximate the wind turbine (100) and a tip portion (207) which extends from the root portion (209) away from the wind turbine (100). A trailing edge insert (220) is positioned between the first shell portion (301) and the second shell portion (302) proximate the root portion (209). The trailing edge insert (220) has a surface (260) which extends between and separates the first shell portion (301) from the second shell portion (302) at the trailing edge (203), such that the insert (220) provides a high lift profile for increased blade efficiency.
