This report discusses the importance of aerodynamics in Formula 1 racing cars and its impact on performance and fuel consumption. It explores the design of rear wings and their role in controlling lift and drag forces. The report also provides a history of Formula 1 and the evolution of aerodynamic technologies. It discusses the different forces involved in aerodynamics and their effects on vehicle performance. The report further examines the front wing, diffuser, and rear wing designs used in F1 cars, as well as the impact of surface roughness on drag force. It also answers research questions related to the difference between airplane and F1 aerofoils, the effect of attachment angle and wing elements on lift and drag coefficients, and other properties that can be investigated using computational fluid dynamics (CFD). Finally, the report includes the design of a Formula 1 car aerodynamic rear wing based on SAE 2018 regulations and recommends the best wing design.
