摘　　要：为了探索适用于长航时飞行器的翼型设计思想、方法和技术 ,进行了新型高升力及失速特性缓和的BUAA K1 BUAA K2翼型的设计研究 .风洞实验结果表明 ,与配置著名GAW 1 GAW 2翼型的机翼比较 ,配置BUAA K1 BUAA K2翼型的机翼最大升力系数和最大航时因子分别提高了 1 5 %和 2 5 % 。Design research of high lift, mild stall airfoils (BUAA K1/BUAA K2) was conducted in order to investigate their design strategy, methods and technology for a long endurance aircraft. Wind tunnel experimental results indicated that, while keep satisfactory aerodynamical features of high\|lift and mild\|stall, the maximum lift coefficient and the maximum endurance factor of a wing with BUAA K1/BUAA K2 high lift, mild stall airfoils can be increased respectively by 15 percent and 25 percent, relative to that of a wing with the well known GAW 1/GAW 2 airfoils.
