Abstract: In this paper, the aerodynamic efficiency of an airfoil passing through a wind tunnel is introduced, and the aerodynamic characteristics of the airfoil are compared with that of the airfoil prior to the flow cavity. The purpose of the study is to investigate the aerodynamic efficiency of the internal guiding cavity on the basis of the ordinary airfoil. The results show that the airfoil has high aerodynamic efficiency in the airfoil strength range. The research results can contribute to improving the maneuverability and high aerodynamic efficiency of aircraft.
