PALA DE AEROGENERADOR OPTIMIZADA

摘要

An optimised wind turbine blade comprising a first component (7) having an aerodynamic profile with a leading edge (11), a blunt trailing edge (13) having a thickness T greater than 2 mm, and suction and pressure sides (17, 19) between the leading edge (11) and the blunt trailing edge (13) and a second component for reducing the blunt trailing edge noise, that can be embodied as a strip of a sharp profile (9) or as a splitter plate (12) having a constant cross section in the spanwise direction of the blade, which is rigidly attached to the blunt trailing edge (13) of the first component (7) in at least a part of the wind turbine blade by attachment means that allow its replacement. The splitter plate (12) can include additional means for protecting the blade against lightning or other electrical discharges connected to the main lightning protection means placed in the first component (7).
