General Motors Full Scale Wind Tunnel Upgrade 2020-01-0687

The General Motors Aero Lab’s Full Scale Wind Tunnel Facility, which came into operation in August of 1980, has undergone the significant upgrade of installing a state-of-the-art moving ground plane system. After almost four decades of continued use the full-scale wind tunnel also received some significant maintenance to other areas, including a new heat exchanger, main fan overhaul, and replacement of the test section acoustic treatment. A 5-belt system was installed along with an integrated vehicle lift system. The center belt measures 8m long, and can accommodate two belt widths of 1100mm and 900mm. Flow quality and other wind tunnel performance parameters were maintained to prior standards which are on par with the latest industry standards. The new 5-belt rolling road system maintains GM’s industry leading vehicle aerodynamic development and the improved acoustic panels ensure GM continues to develop vehicles with leading class acoustics.
