Abstract
A wind turbine having at least a blade comprising a first component 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, attached to the trailing edge and/or to the leading edge of the first component in at least a part of the blade, comprising one or several upwards and/or downwards deflectable flaps that allow changing the flow over the blade, in which a device for deflecting each of the flaps comprises an actuating force or torque provided by scaling devices connected to a predetermined location in the outer surface of the blade, through a duct, so that the changes in the wind pressure at this location can be scaled to the actuating force or torque.
