The angle of attack is a key parameter that significantly influences the aerodynamic characteristics of an aircraft wing, particularly the drag coefficient (Cₓ), which directly affects flight performance and fuel consumption. In this study, Computational Fluid Dynamics (CFD) simulations are performed for the YAK-130 aircraft wing over an angle-of-attack range from 0° to 35° in order to investigate the effect of the angle of attack on the drag coefficient. The obtained results provide insight into the aerodynamic mechanisms governing drag variation and contribute to a better understanding of the aerodynamic behavior of the YAK-130 aircraft at both low and high angles of attack.
