以Wilson理论为基础,采用Matlab对风力机气动外形设计程序,对叶片的弦长、扭角进行优化设计,并对优化结果进行比较分析,叶片截面的风能利用系数均高于0.5,最高可达到0.56,非常接近贝茨极限的0.593,验证了优化叶片的工作性能,为大功率风力机叶片的设计开发提供了理论依据.%Taking the Wilson theory as a foundation, the design project of the anemometer air-operated contour and the optimization design of the chord length, and the torsion angle of the blade are carried on with the help of the matlab and then a comparative analysis is made on the optimized results. The coefficient of wind energy utilization of the blade cross sections is higher than 0. 5; sometimes it goes up to 0. 56, very close to the Betz limit of 0. 593. The performance of optimized blade is verified,thus providing a theoretical basis for the design and development of high-power wind turbine blades.
