Abstract
In aerodynamic applications, there are on going efforts to improve the aerodynamic performance of the airfoils used. In the aerospace sector itself, many apply modifications to slats and flaps that focus on the effects of adding these elements. Several slat and flaps configurations are analyzed using computational fluid dynamics (CFD) simulations at various angles of attack. The results will be compared with airfoils without slats and flaps. The results show that NACA 4412 with a combination of 20 m slat length and 20 m flaps shows a more effective configuration in producing high lift compared to no modification. The lift coefficient (CL) reaches a peak value of around 3.062263 at an angle of attack of around 28°-29°. The lift coefficient increases by about 2 times compared to no modification. This shows that this configuration can produce higher lift at higher angles of attack, and is able to delay stall. This study improves the understanding of the aerodynamic behavior of NACA 4412 and provides data to guide design improvements. Keywords: NACA 4412, Slat, Flaps, Computational Fluid Dynamics (CFD), Lift coefficient, Drag coefficient
