Airfoil geometry plays a key role in determining an aircraft wing’s aerodynamic performance. Parameters such as camber, thickness, and profile shape strongly affect lift, drag, and operating limits under different flight conditions. This study examines the impact of airfoil shape through three aspects: comparing symmetric and cambered airfoils in terms of maximum lift, evaluating the effect of thickness on drag and critical Mach number, and analyzing three typical airfoils across various speeds. Results indicate that cambered airfoils provide higher maximum lift, while thickness significantly influences drag and critical Mach number, with each airfoil showing distinct performance in different flight regimes.
