Design of the Wind Turbine Blade
Abstract: Wind turbine blades is one of the important parts of wind power system, which is a direct impact on wind generator power, efficiency and size. This project is designed to 1MW wind turbine blades, including the calculation of the shape and size of the data structure, select the blade airfoil and materials. In calculating the data, select the Wlison design model and use the MATHLAB to optimize the design blade profile data. In the case of the actual operation, but also consider how to prevent harm caused by lightning leaves, design lightning protection system, because the blades wind power system is the most expensive part. 30 m overall length blade airfoil selected N4415 type blade is made by FRP, structural stability, the design wind speed 12m / s, the speed of about 24r / min, the overall power coefficient of about 30%.
