The invention discloses a cyclone blade. The tail edge of the cyclone blade comprises at least one level of fractal structure. The ith-level fractal structure comprises at least one ith-level fractal face or at least one ith-level section fractal face. The (i+1)th-level fractal face is obtained by cutting at least one polygon on at least one ith-level fractal face in the direction perpendicular to the thickness direction of the blade, wherein the (i+1)th-level fractal face corresponds to the side face, in the thickness direction of the blade, of at least one cut-off polygon. At least one ith-level fractal face is divided by j polygons into (j+1) ith-level section fractal faces. The side face, in the thickness direction, of the tail edge of the blade serves as the 0th-level fractal face. At least one fractal face or section fractal face is provided with at least one fuel hole, i is larger than or equal to 0, j is larger than 0, and i and j are integers.
