    Effect of Taper Configuration on the Aerodynamic Load Distribution and Efficiency of Wings in Steady Flow by Onur Son

    Published 2025-01-01
    “…The spanwise location of the center of lift is also employed to quantify the approximation of spanwise lift distribution to the elliptic lift distribution. The maximum efficiency and corresponding optimum taper ratios are determined by three methods (lift-to-drag ratio, span efficiency factor and spanwise center of lift) and these methods are shown to yield the similar results.…”
