| Abstract: | Based on the airfoil design requirement of high lift-to-drag ratio and small pitch-down moment for tailless aircraft,the effects of forward-loading and aft-unloading on airfoil aerodynamic characteristics was investigated by CFD.Applying the idea of forward-loading and aft-unloading,the distribution of thickness and camber of airfoil were optimized,and the airfoil design with higher lift-to-drag ratio and small pitch-down moment has been successfully performed.Results indicated that this airfoil design meth... |
