摘  要:
针对动量叶素理论气动外形设计方法中迭代初值需要人为经验定义的问题,运用Wilson算法计算风机叶片外形参数,使用Matlab中的Cftool工具箱对外形数据进行拟合修正,并将修正后的数据作为迭代初值进行二次修正,从而使叶片外形设计更为科学。通过与普遍方法计算的叶片外形设计方法进行Cp值对比,验证了计算方法的正确与实用性。

摘  要:
Aiming at the problem that iterative initial value of the aerodynamic shape design is defined by experience based on blade element theory,the paper calculated the shape parameters of wind turbine blade by using wilson algorithm,fitted the shape data by using Cftool toolbox in Matlab,used the corrected data as iterative initial value to modify secondly,and then obtained a scientific shape parameter. Through the comparison with Cpvalues between the general method and new method,the correctness and feasibility of the method is verified.
