Design and CFD Analysis of a Rear Wing of a Motorsport Car

Abstract

The rear wing of a motorsport car is one of the 3 main components to produce the downforce required by the car to take a corner with the maximum speed possible. This paper aims to design and analyse the rear wing of a motorsport car. The design consists of a lower wing element (main plane), an upper wing element (flap) and the endplates. In this study, the rear wing is designed as per the FIA 2020 F1 technical regulations and is analyzed using Computational Fluid Dynamics (CFD). The rear wing model is designed using Autodesk Fusion 360 and the analysis is made using Autodesk CFD. Benzing airfoils were used in this project as the wing elements. The results of the stock and modified model are compared and discussed. The results show how the modified version of the endplate has better aerodynamic properties than the stock model. The whole rear wing assembly has also been analysed and the results were discussed.
