摘　　要：本文给出了DU93-W-210翼型在中国空气动力研究与发展中心4 m×3 m低速风洞中进行风洞试验的气动力特性数据,实验结果显示翼型具有很好的气动力特性。翼型在攻角大于200时,仍未表现出明显的失速特性,当Re=3.0×106时,Cl～α曲线还处在明显爬升阶段,Clmax=1.454;翼型在自由转捩和固定转捩两种模式下气动力特性曲线基本是一致的,说明翼型具有低的粗糙度敏感性。The aerodynamic data of DU93-W-210 airfoil wind tunnel experiments conducted in CARDC 4 m x 3 m low speed wind tunnel is given in this paper. The experimental results show that airfoil has good aerodynamic characteristics. While the angle of attack greater than 20°, the airfoil still does not show the obvious characteristic of the effectiveness. While Re = 3.0 x 106, C1 ct curve is still in the climb phase, Clmax = 1. 454. The aerodynamic characteristic curve of airfoil is consistent under free and fixed transition. It declares airfoil has low roughness sensitivity.
