A low-speed wind-tunnel investigation was conducted to examine the effect of aspect ratio on ground effect. The characteristics of the wing and its section (a S8036 profile) were established at Re=1.2×105. The results indicate that ground effect is highly beneficial in augmenting lift, such that marked increases in the maximum lift-to-drag ratio may be realized. Finite wings in ground effect benefit from a reduction in vortex drag, as well as a lift increase, yielding greater gains in efficiency than achievable for an airfoil. The evaluation of analytic relations for estimation of the finite wing lift-curve slope and drag due to lift showed close accord with experiment.
