    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.
