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, in which the second component () comprises an upwards and/or downwards deflectable flap () that allows changing the flow over the blade and in which the means for deflecting the flap () comprise a stiff plate () inserted between the first component () and the flap () and stiff plate actuating means ().

Wind turbine blade with cambering flaps

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. An upwards and/or downwards deflectable flap allows changing the flow over the blade, in which the unit for deflecting the flap is a fluid inflatable unit placed in a flap inner chamber close to the first component and in which the wind turbine comprises a unit for controlling the inflatable unit depending on the wind situation and/or the blade loads.
