摘要

The Windshear Rolling Road Wind Tunnel in Concord, North Carolina, is a full-scale commercial wind tunnel conceived primarily as a facility to serve the various motorsports communities, although it has already expanded beyond that base into production car and truck testing. The wind tunnel is a 3/4-open-jet, closed-return design with a 16.7 m~2 nozzle, a wide-belt moving ground plane, and a top speed of 80 m/s (180 mph). This paper describes the project history and design philosophy of the wind tunnel, commissioning results, and an overview of the force measurement methods on the wide-belt rolling road. Some results of a recently-completed correlation program are presented, along with performance validation results that include repeatability and reproducibility as well as an assessment of boundary corrections.
