中文摘要：

为提高风力机的功率系数Cp，对平板V型小翼的参数进行了优化试验．采用正交试验法选取5个基本参数，分析了各个参数对风力机功率的影响，找出了对其影响明显的参数以及小翼尺寸与叶片尺寸的相对关系．

英文摘要：

Optimization of flat V tip vane geometry parameters were tested to upgrade power coefficient of wind turbine Cp. Orthogonal tests were carried out to analyze influence of five basic parameters of tip vane on Cp. The most prominent parameter on Cp and the relative relationship between dimensions of tip vane and blade have been found.
