In modern motor sports, the concept of aerodynamics has become one of the most important and most developed factors. Good aerodynamics, i.e. the lowest possible air resistance, leads to lower fuel consumption and thus to higher speeds and time gains. It also increases the safety and comfort of driving.
Optimum results and significant improvements are only achieved through the interaction of many individual details. These can be revised air outlets that avoid disturbing turbulence in the wheel arches or generous floor/rear axle panels that offer the air as little contact surface as possible. But even minor modifications to the front and side sections, additional ducts on bumpers and fenders or a redesign of the rear spoiler have a major impact on the overall result. For a comprehensive analysis of aerodynamics, all data and factors are already given in your vehicle. The first step is the correct and detailed acquisition of all vehicle data by means of a 3D scan.
Subsequently, a model of a three-dimensional object is constructed by means of a CAD software (Computer Aided Design), which allows the illustration from any direction.
The subsequent CFD software (Computational Fluid Dynamics) simulates the wind tunnel on the virtual model so that various adjustments and configurations can be made to obtain an understanding of the various interactions.
The greatest challenge is to evaluate and verify the necessary data with sound knowledge and experience. In doing so, pressure distributions and flow structures have to be determined precisely, local forces and flow variables on surfaces have to be evaluated, and finally, modes of action of optimization measures have to be understood.
