We as the aerodynamics department are responsible for both the design and production of the bodywork of the Forze IX. The aerodynamic design goals are to minimize drag, maximize downforce and assure proper airflow for cooling. For every potential design alteration, an extensive airflow simulation is run by means of Computational Fluid Dynamics (CFD) to ensure these design goals are met. When the design is finalized, also the production is done by the Aerodynamics department. With the use of carbon fibre, it is made sure that the bodywork is as lightweight and strong as possible to handle all aerodynamic loads.
My role this year is to translate the geometric design of our aerodynamic surfaces of the new car from CAD to physical parts. We produce our bodywork from carbon fiber and we manufacture almost every component ourselves. This means we need to design and manufacture tooling needed for production and eventually laminate the carbon fiber parts. Alongside the production, I work on some side projects within the aerodynamics department, such as CFD validation.
Together with Thijs I work mostly on generating the new outer geometry of the car. This is done by performing CFD simulations and analysing the results of these. As aero department we strive to meet the harsh cooling requirements of a hydrogen-electric race car, while maintaining an acceptable aerodynamic performance to enhance the ability of the car to race. Additionally I am also responsible for internal fluid flow simulations of the car.
This year we are designing a complete new aero package compared to previous years. Increased cooling requirements have a large influence on our design choices, and we are always searching for the best balance between aerodynamic- and cooling performance. Martijn and I are responsible for finding a bodywork geometry which fulfills all design goals set at the beginning of the year, and we test every iteration on the geometry extensively in CFD.
