摘　　要：对适用于风力机的新翼型FFA W3 211和FFA W3 360进行了风洞实验研究,得到了两种翼型在不同雷诺数下的气动性能及其在大攻角下的失速特性。实验结果与采用低雷诺数翼型分析和设计软件XFOIL的计算结果进行了比较,其最大升力系数对应攻角偏差小于1,在-10°～+18°范围内,升力系数的平均相对偏差为5 1%,两种结果的一致性很好。A wind tunnel test research was conducted to gain the aerodynamic performances of the HAWT new airfoils FFA-W3-211 and FFA-W3-360 at different Reynolds numbers and their stall characteristics at high angle of attack.The comparisons of the performances between the test and the calculation using the software XFOIL,which is a kind of analysis and design software for low Reynolds number airfoil,were made.The results showed that the difference of the angles of attack at which the maximum lifts appear is less than 1° and the average relative difference of lift coefficients between -10° to +18° is 5.1%,they were in good agreement.
