Rotor blade for horizontal axis wind turbines is variable in longitudinal axis to increase rotor power, has base module attached to hub, module angled in the direction of rotation in rotor plane

摘要

The rotor blade has a base module (4) attached to the hub (2) and a module (5) angled in the direction of rotation and arranged in the plane of the rotor. The angled module consists of one or more angled parts. The bend angle of each individually angled module or part with respect to the blade is between 5 and 90 degrees and the bending point (3) can be variably specified along the blade's axis.
