Beschreibung
Zusammenfassung:	The invention relates to a wind turbine blade based on fractal theory design. The wind turbine blade comprises a blade main body and a blade fractal tail edge, wherein the blade main body is located at the front part of the blade relative to the incoming flow direction, the blade fractal tail edge is located at the rear part of the blade relative to the incoming flow direction, a plurality of holes are distributed in the blade fractal tail edge, and the holes run through the pressure surface and the suction surface of the whole wind turbine blade. The wind turbine blade is simple in structure, a mechanism for inhibiting stalling is easy to achieve, and compared with a device with passive control on stalling characteristics, the cost is greatly lowered.
