Abstract: A load mitigation arrangement of a non-mounted rotor blade, includes at least one actuatable lift-modification device arranged on a surface of the rotor blade; a monitor configured to estimate the magnitudes of loads acting on the non-mounted rotor blade; a controller configured to actuate the lift-modification device on the basis of the estimated magnitudes to mitigate the loads acting on the non-mounted rotor blade. Further provided is a rotor blade assembly, and a method of performing load mitigation on a non-mounted rotor blade.

Abstract: A rotor blade of a wind turbineis provided, the rotor blade including a lift modifying device having at least one fluid jet module and at least one compressed fluid sources, wherein the at least one fluid jet module includes multiple fluid jets, which are fluidically connected to the at least one compressed fluid source, whereby the at least one fluid jet module is mounted as an add-on onto an outer surface of the suction side or the pressure side of the rotor blade. Also provided is a method for installing this rotor blade, whereby a rotor blade is provided and the at least one fluid jet module is mounted as an add-on onto the outer surface of the suction side or the pressure side of the rotor blade.

Abstract: A lift modifying device for a rotor blade of a wind turbine is provided, the lifting modifying device including at least one fluid jet module and at least one compressed fluid source, wherein the at least one fluid jet module includes multiple fluid jets, which are fluidically connected to the at least one compressed fluid source, the at least one fluid jet module is configured to be arranged at a suction side or a pressure side of an airfoil of the rotor blade, and the at least one fluid jet module is configured to generate a fluid curtain separating an air flow on the suction side the pressure side of the airfoil, when the rotor blade is provided with the lift modifying device on its suction side or pressure side and the at least one compressed fluid source supplies compressed fluid to the at least one fluid jet module.
