OPTIMISED WIND TURBINE BLADE

摘要

The invention relates to an optimised wind turbine blade including: a first component (7) having an aerodynamic profile with a leading edge (11), a blunt trailing edge (13) with 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 (9, 12) for reducing the noise from the blunt trailing edge, having a constant cross-section along the radius of the blade, which is securely joined to the blunt trailing edge (13) of the first component (7) in at least part of the wind turbine blade using coupling means that enable same to be replaced.
