An experimental and computational study on improvement of lift-drag characteristics of transonic airfoil with passive ventilation has been conducted. Transonic airfoils with passive ventilation have been selected in the present study. For the passive ventilation, porous wall on the upper surface of wing or a pair of slits, which are located on the wing surface, is used. Surface pressure distributions on the airfoil are measured in order to investigate the effect of passive ventilation to the improvement of lift-drag characteristics of the airfoil. Lift and drag coefficients of the airfoil are calculated by using those surface pressure distributions. The results show the passive ventilation could improve lift-drag characteristics of the airfoil in some cases and the optimal selections of the shape of airfoil and location of passive ventilation are requested.
