Car Development

The best performance requires the best preparation.

The aerodynamic performance of race and production cars are validated and 
enhanced by RUAG Aviation’s Wind Tunnels. Using precise scale models for
maximum data accuracy, aerodynamic development is optimised through the 
evaluation of real-world effects within a controlled Environment.

Race Car Development

Scale models are used in the Automotive Wind Tunnel Emmen (AWTE) to develop and optimize the aerodynamics of cars competing in various race series such as LeMans, Formula 3, WTCC and others.

The AWTE and its infrastructure are especially adapted to automotive testing with models up to 50% scale. Standard equipment includes a moving belt, a multi-axis model manipulator and a model shaker for dynamic motion testing. Our customers rely on our proven competence and flexibility, as well as our infrastructure, kept up to date constantly, to allow efficient test campaigns. Clearly defined calibration procedures, wind tunnel processes and check lists according to ISO 9001 allow us to meet the highest quality standards.

Production Car Development - Models

Rain Test

The Large Wind Tunnel Emmen (LWTE) accepts full-scale cars in its test section for performing water management tests. Water mixed with a fluorescent dye is injected upstream of the car. The test object is illuminated with multiple UV lamps and the distribution and flow of the water droplets is documented with video or still cameras. The functionality of windshield wipers and the soiling due to water droplets on the side window and the rearview mirror can thus be studied.
