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15%和25%,并且实现了同时具有高升力和失速特性缓和的气动特性.Abstract: 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.
