MTS Systems Corporation announced that the world’s largest rolling road system is now fully operational at DNW (German-Dutch Wind Tunnels), one of the world’s most advanced specialized wind tunnel test facilities, located 100 kilometers northeast of Amsterdam, the Netherlands.
Deployed within an aerodynamic wind tunnel, the system provides a moving ground plane that is critical for accurately replicating the unique dynamics surrounding aircraft takeoffs and landings. Aircraft manufacturers use data generated by these tests to evaluate critical design elements, such as how engines are integrated with wing designs and the effects of landing gear and high lift devices.
At six meters wide, DNW’s new rolling road is the largest of its kind, operating at speeds up to 80 meters per second (approximately 180 miles per hour) — equal to that of rolling road systems used for testing Formula 1 race cars. Even at maximum speed, the system’s moving belt is designed to remain flat to ensure simulation accuracy. The moving belt also exhibits exceptional reliability and durability, especially critical for withstanding the rigors of powered takeoff simulations – during which engine exhaust flow is also simulated.
With the new rolling road system, DNW is able to offer their aerospace customers the most realistic simulations possible while benefiting from high levels of uptime. DNW is particularly satisfied with the system’s flatness and reliability, which enables their customers to simulate required test conditions with very high levels of precision and efficiency.
