| 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. |
| Keywords: | airfoils stalling characteristics endurance property |
