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.

1. A wind turbine having blades wherein at least one of the blades consist of a first component (11) having an aerodynamic profile with a leading edge (5), a trailing edge (7), and suction and pressure sides between the leading edge (5) and the trailing edge (7) and a second component (13) attached
1. A wind turbine having blades wherein at least one of the blades consist of a first component (11) having an aerodynamic profile with a leading edge (5), a trailing edge (7), and suction and pressure sides between the leading edge (5) and the trailing edge (7) and a second component (13) attached to the end of leading edge (5) and/or to the trailing edge (7) of the first component (11) in at least a part of the blade, wherein: the second component (13) consist of one or several upwards and/or downwards deflectable flaps (15, 15′) that allows changing the flow over the blade;the deflectable flaps (15, 15′) consist of suction and pressure sides;each of said deflectable flaps (15, 15′) has means for deflecting which comprise a scaling device (21) that, depending on the pressure detected at a predetermined location (17), to which the deflectable flap is connected by means of a duct (19), generates an actuating force or torque proportional to the changes in the wind pressure at said location (17). 2. A wind turbine according to claim 1, wherein the attachment of said one or several flaps (15, 15′) to the second component (13) is actuated by the force generated by the scaling devices (21) that deflects one or several flaps (15, 15′). 3. A wind turbine according to claim 2, wherein the scaling device (21) generates a force that deflects directly one or several flaps (15, 15′). 4. A wind turbine according to claim 2, wherein the scaling device (21) generates a force that controls specific flap deflecting means (23) of said one or several flaps (15, 15′). 5. A wind turbine according to claim 1, wherein the attachment of said one or several flaps (15) to the first component (11) is actuated by the torque generated by the scaling devices (21) which deflects one or several flaps (15, 15′). 6. A wind turbine according to claims 1, wherein the width W of said one or several flaps (15, 15′) is comprised between 1-20% of the chord length C of the blade in the center of the flap (15, 15′). 7. A wind turbine according to claim 6, wherein the width W of at least one flap (15) is constant along the blade. 8. A wind turbine according to claim 6, wherein the width W of at least one flap (15′) is variable along the blade. 9. A wind turbine according to claim 1, wherein said one or several flaps (15, 15′) are attached to the blade leading edge (5) and/or to the blade trailing edge (7) in a section having a length lesser than ⅓ of the blade length L. 10. A wind turbine according to claim 1, wherein said one or several flaps (15, 15′) are made in one piece of a flexible material. 11. A wind turbine according to claim 10, wherein said one or several flaps (15, 15′) are made of rubber. 12. A wind turbine according to claim 10, wherein said one or several flaps (15, 15′) are made of a pultruded fiber glass reinforced composite.
