Large-scale wind turbine intelligent blade
2014
The invention discloses a large-scale wind turbine intelligent blade. The intelligent blade comprises a blade body and a tail edge wing flap which is connected with the cutting-off tail edge of the blade body; the tail edge wing flap comprises n divided deflection rubber surfaces, two two-end connecting transition segments and n-1 middle connecting transition segments, wherein n is larger than or equal to 1 and smaller than or equal to 3; the two-end connecting transition segments and the middle connecting transition segments are made of flexible materials; every two adjacent divided deflection rubber surfaces are connected through the corresponding middle connecting transition segment, and therefore the two adjacent divided deflection rubber surfaces and the corresponding middle connecting transition segment are in series connection to form a total deflection rubber surface; and the two ends of the total deflection rubber surface are connected with the blade body through the two-end connecting transition segments. According to the intelligent blade, the two ends of the tail edge wing flap are in smooth transition with the blade body, and the tail edge of the blade is continuous, so that the flow quality of the tail edge is improved. Flow-around flow stability of the blade is improved, deflection of the tail edge wing flap is controlled, and therefore the local aerodynamic load control and overall load optimal control over the blade can be achieved.
