摘要:
A wind turbine having at least a blade comprising a first component (11) having an aerodynamic profile with a leading edge, a trailing edge and suction and pressure sides between the leading edge and the trailing edge, and a second component (13), attached to the trailing edge and/or to the leading edge of the first component (11) in at least a part of the blade, comprising one or several upwards and/or downwards deflectable flaps (15, 15') that allow changing the flow over the blade, in which the means for deflecting each of said flaps (15, 15') comprise an actuating force or torque provided by scaling devices (21) connected to a predetermined location (17) in the outer surface of the blade, through a duct (19), so that the changes in the wind pressure at said location (17) can be scaled to said actuating force or torque.
