Abstract
Aerodynamic testing plays a vital role in the early stages of automotive design, enabling engineers to optimize drag, lift, and stability before committing to costly production tooling. While Computational Fluid Dynamics (CFD) provides valuable insights, physical wind tunnel testing remains the gold standard for validation. This paper examines the use of clay-modeled prototypes in aerodynamic testing, emphasizing the importance of lightweight construction through hollow-core designs to enhance testing efficiency. Practical considerations in wind tunnel operation, scaling, and model preparation are discussed, with a focus on improving the accuracy of aerodynamic data in the initial phases of vehicle development.
