Enhance the fidelity of aerodynamic wind tunnel testing by integrating high-speed moving ground plane systems that accurately replicate ground effect conditions under test vehicles and around rotating wheels. Available in numerous configurations, Flat-Trac Rolling Road Systems are deployed worldwide to optimize racing vehicle performance, develop more fuel efficient passenger cars and study aircraft ground interactions during takeoff and landing.
MTS has delivered numerous custom-engineered rolling roads to racing teams, OEMs and contract labs worldwide, including: 16 single-belt, 8 five-belt systems, and 3 interchangeable systems
Through-the-belt wheel force measurement provides highly accurate measurement of individual tire lift and down forces; proprietary vacuum pre-loaded air bearings maintain flat belt operation
Stainless steel belts exhibit outstanding durability and long life, operating at speeds approaching 325 kph for up to 300,000 km
Automated configuration features and intuitive user interfaces reduce vehicle setup time and improve test productivity
