In this study, the aerodynamic performance of seven different airfoils named CLARK Y, YH, Curtis C-72, FX 66-S-196 V1, NACA4412, NACA4415, and NACA4418 was numerically investigated under angles attack ranging from 0° to 30° in increments 5°. 2D (two-dimensional) CFD (Computational Fluid Dynamics) models were created performed steady-state conditions. When changes lift coefficient drag with exam...
