摘要
在叶片翼型设计过程中,提出了翼型型线的集成设计理论和方法,阐述了保角变换理论及其在翼型设计过程中的应用,引入了级数思想,推导出了能够广泛应用的翼型集成表达式,构造出了三种典型的翼型曲线,最后对常用的两种翼型进行了集成表达,并比较分析了级数项对翼型形状的影响,验证了函数表达方程的集成性和通用性。该研究突破了现有翼型数学模型固有特性的限制,提出的函数集成表达方式能够表征翼型的本质特征,为风力机叶片翼型的优化设计理论与方法研究拓宽了思路。
Based on the conformal transformation and series theory, an integration equation was developed for the airfoil profile expression. From the integration equation, three typical profiles were presented. In order to see the generality of the integration equation, two airfoils were able to expressed. The inherent characteristics of airfoil profiles model are broken through and the design method of airfoil profiles for wind turbines is broaden. Due to the simple form, the new integration equation has more advantages in the deisgn stage than classic airfoil profile models.
