LIFT MODIFYING DEVICE FOR A ROTOR BLADE, ROTOR BLADE OF A WIND TURBINE AND METHOD FOR MODIFYING THE LIFT OF A ROTOR BLADE

摘要

The invention relates to a lift modifying device (20) for a rotor blade (10) of a wind turbine, the lifting modifying device (20) comprising at least one fluid jet module (21) and at least one compressed fluid source (22), wherein the at least one fluid jet module (21) comprises multiple fluid jets (23), which are fluidically connected to the at least one compressed fluid source (22), the at least one fluid jet module (21) is configured to be arranged at a suction side (17) or a pressure side of an airfoil of the rotor blade (10), and the at least one fluid jet module (21) is configured to generate a fluid curtain (A) separating an air flow (W) on the suction side (17) or the pressure side of the airfoil, when the rotor blade (10) is provided with the lift modifying device (20) on its suction side (17) or pressure side and the at least one compressed fluid source (22) supplies compressed fluid to the at least one fluid jet module (21). Further, the invention relates to a rotor blade (10) having the lift modifying device (20) and a method for modifying the lift of a rotor blade (10).
