Designing an airfoil is one of the essential parts for the blade development. This study was conducted to find the optimal airfoil using the DesignFoil program. For this, the coordinates were derived using the NACA 4-digit series and 5-digit series formulas, and the obtained initial cross-sectional shape was input into the DesignFoil program, and then the lift-to-drag ratio was optimized for each parameters such as the pitching moment, Reynolds number, Mach number, thickness ratio and angle of attack. The result showed that the airfoil section coordinates were optimized and then a designed airfoil was analyzed, using VisualFoil program that analyzes airfoil to verify it’s performance and were used for the determination of the blade geometry.
