Abstract : Based on force measurements, oil flow observations, and eddy measurements in low air-speed wind tunnels, the paper studies the mechanism underlying the effect of canard wing positions on the aerodynamic characteristics of swept-forward canard wing configurations. As shown in studies, canard wing positions play the most significant role with respect to aerodynamic characteristics. Improvements in characteristics through a large incident angle in the swept-forward canard wing configuration depends on the relative position and the mutual control of the eddy at the leading edge of main wing. Based on the experimental results of an assembly with swept-forward and swept-back canard wing as well as the main wing, the paper presents the two- dimensional shapes of the canard and main wings, as well as their relative positions when adopting canard configuration. in addition, the authors express some of their views on the configuration of dual swept forward wings.
