N2 - In this study, the computational accuracy of BCM compressible Euler solver was first validated with NACA0012 airfoil. The result of validation showed that BCM was in good agreement with the TAS code. Next, the BCM solver was applied to the aerodynamic design optimization problem of shock free airfoil. The airfoil without a shock wave was successfully designed. Finally, data mining was performed using POD in order to understand the characteristics of configuration for the obtained airfoils by optimization. As a result, it is revealed that the acceleration of flow on upper surface is reduced by the flattened upper surface of airfoil to weaken a shock wave.
