This study efficiently evaluates the aerodynamic impact of local leading-edge deformations using CFD. We confirm that leading-edge geometry significantly influences loss generation. By comparing two different LE shape airfoils, this research identifies shapes that maintain robust aerodynamic performance, offering vital guidelines for designing airfoils resilient to geometric uncertainties.
