| 摘 要： | 本文以偏微分方程造型为基础,提出了一种基于椭圆型方程的扭叶片三维型面直接设计方法,详细推导了叶型曲面函数,给出了型面方程的求解及其前后缘修正。该方法具有设计叶型曲面自然光顺,设计参数少且各参数具有明显的几何意义,叶型曲面调整方便,利于采用非数值优化算法对其进行气动优化等优点。文中给出了设计实例,并通过数值实验分析了所设计叶片型面的流动特性。分析结果表明设计叶片具有良好的气动性能,同时也证明了本文提出的基于椭圆型方程的扭叶片三维型面设计方法的可靠性和实用性。

| Abstract: | This paper presents a method for 3D twist blade curved surface design based on the elliptic equations using Partial Differential Equation solutions. The function of the curved surface is deduced in details and the corresponding solutions with the modification for leading edge and trailing edge of the designed blade are described. Few parameters can be used to adjust smooth curved surface of the designed blade in this method. The design case and corresponding aerodynamic performance using numerical method are presented. The obtained results show that the designed blade has excellent performance. The practicability and reliability of the present designed method are also illustrated. |
