Best NACA airfoil database for racecar4/29/2024 In comparison with the conventional wing and fuselage design, BWB design has been proved to have noteworthy enhancements in terms of aerodynamic efficiency. The benefits of this kind of aircraft mainly arises due to distributed structural and aerodynamic loads, which leads to better aerodynamic performance and provides lighter structural weight as well. The requirement to design an eco-friendly aircraft that can produce higher lift which is aerodynamically efficient has directed the designers to develop the Blended Wing Body (BWB) aircraft concept. According to study 3D results are more realistic due to the viscosity inclusion. The effect of viscosity is not considered in two-dimensional analysis but in three-dimensional analysis viscosity is considered. Cd values, which can get from Two-dimensional simulation & three dimensional simulations. Three dimensional simulations for selected airfoils done by using "Solid Works" software for selecting suitable airfoil and comparing Cl vs. After analysis among five airfoils three airfoils were chosen (NACA: 6318, 9520, 9525) which having higher Cd and lower Cl values. For two-dimensional analysis there were five airfoils used (NACA 4-digit airfoils) the analysis done by using Xfoil open source software, aimed at obtaining Pressure Coefficient (Cp), Lift Coefficient (Cl) and Drag Coefficient (Cd) graphs. Performance of NACA airfoils by using "Xfoil" software for two-dimensional simulation and Solid Works for three dimensional simulations was compared. In this report 2D and 3D performance of NACA airfoils was obtained. A product of air resistance which acts to slow the car down. In simple terms FSAE car aerodynamics have two primary concerns, the creation of down force to help push the car tires on to the track and improve cornering forces and the minimization of drag.
