It is known that sinusoidal leading edge is effective in low Reynolds number region. However, the effect of the wavelength and the amplitude of the sinusoidal leading edge on the wing performance has not been clarified yet. In this study, we carried out the wind tunnel experiment and numerical simulation to investigate the effect of the wavelength and the amplitude of sinusoidal leading edge on the wing performance. As a result, it was found that amplitude-to-wavelength ratio λ/A can be used to estimate the increase amount of the lift force in λ/A≦4, however, in λ/A≧4, the increase amount of the lift differs depending on the changing parameter.
