  • With the goal of maximizing lift-to-drag ratio, the optimization of three-dimensional wing-s section thickness and twist angle is discussed. Euler equations as flow field sovler and Powell method are used as design tools, and the wing-s aspect shape and airfoil are fixed. The thicknesses of wing sections on the semi-wingspan relative position of 0.1, 0.2, 0.3, 0.8, 1.0, with the additional twist angle are chosen as the optimal control factors. The distribution of wing-s thickness and twist angle is obtained on the subsonic conditions with relative high lift-to-drag. The subcritical and supercritical computation of Lockheed-AFOSR wing B cases show that nonlinear distribution of thickness and negative twist angle could ameliorate the condition of flow field around the wing, which leads to higher lift-to-drag ratio, the optimization method is effective.
