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.
Claims8
A method of performing load mitigation on a non-mounted rotor blade of a rotor blade assembly, wherein the method comprises the steps of:
- arranging an actuatable lift-modification device of a load mitigation arrangement on a surface of the non-mounted rotor blade;
- monitoring loads acting on the non-mounted rotor blade;
- actuating the actuatable lift-modification device based on the monitored loads, and
- removing the actuatable lift-modification device after the non-mounted rotor blade has been mounted to a hub of a wind turbine.
