    Aerodynamic Characteristics
    Author(s): Paolo Di Sia*

    In the low-Reynolds-number range below Re = 60,000, SD7003 and Ishii airfoils are referred to as high-performance low-Reynolds-number airfoils with a comparatively high lift-to-drag ratios. Although the aerodynamic characteristics at particular Reynolds numbers are thoroughly studied, research is lacking on how Reynolds numbers affect the aerodynamic characteristics that become pronounced for general low-Reynolds-number airfoils. This study investigates the Reynolds number dependence on the aerodynamic performance of those two airfoils. The results demonstrate that the Ishii airfoil is especially less hooked in to the Reynolds number of the lift curve compared to the SD7003 airfoil. Although there's a small difference within the high angles of attack above the utmost lift coefficient, the lift slope hardly changes, even when the Reynolds number varies... Read More»
