Embodiment Construction
[0035] The specific embodiment of the present invention will be further described below in conjunction with the accompanying drawings, but this should not limit the scope of protection of this patent.
[0036] figure 1 and figure 2 A sectional view of a wind turbine blade airfoil that can improve stall characteristics based on fractal optimization according to the present invention is shown. In this example, the airfoil of the wind turbine blade adopts NACA0012, which is widely used in the wind power industry, but the airfoil structure of the present invention is not limited thereto.
[0037] Depend on figure 1 It can be seen that the wind turbine blade of the present invention mainly includes a blade main body 1 and a blade trailing edge 2 .
[0038] The main body 1 of the blade is made of fiberglass, and the trailing edge 2 of the blade can also be made of fiberglass, which is characterized by high strength, light weight and aging resistance.
[0039] still refer to fi...
