Description
Airfoils, an invention known since the 19th century, are among the most crucial structures discovered by humans. Besides their obvious presence in aircraft wings, airfoil profiles are also used in the design of fans, drone propellers and helicopter blades, and even in foiling motorboats. The physical principles of a wing are fundamentally simple: lift force is generated through pressure differences between the upper and lower surfaces of the wing.
In this study, an investigation was conducted on the NACA 64A-715 airfoil, which is part of the 6-digit NACA profiles. Numerical analysis was performed using Computational Fluid Dynamics (CFD) for both 2D and 3D geometries. An iterative numerical refinement of the geometry was carried out to enhance lift force and increase lift to drag ratio, comparing the results with the original profile. Additionally, the winglets were analyzed to minimize energy losses caused by turbulent eddies. The hydrodynamic properties were examined in relation to the wing’s angle of attack. The received data resulted in the creation of high-quality hydrofoil design for solar powered race boat "Celka".
