摘　　要：二维翼型气动特性决定整个转子叶片的气动特性,分析二维翼型气动特性十分必要。文章介绍了翼型绕流及其升阻效应,并且对经典翼型NACA4415进行气动特性数值模拟计算,对翼型气动特性影响因素雷诺数、相对厚度、相对弯度等进行了研究。对翼型气动特性数值计算及其影响因素的研究,为三维叶片设计提供可靠参考,并对进一步叶片优化设计具有重要意义。It is necessary to analyze two-dimensional airfoil aerodynamic performance that determines aerodynamic performance of entire rotor blades. In this paper, flow around airfoils and lift-drag effect are introduced, aerodynamic characteristics of searched that factors such as Reynolds number, classical NACA4415 airfoil is simulated, and it is rerelative thickness and relative curvature, influence on the aerodynamic performance. The research on simulations of airfoils aerodynamic performance and its influence factors provides a reference for three-dimensional blade design, and has great significance for further optimizing the design of blades.
