The General Motors Engineering Staff Aerodynamics Laboratory - A Full-Scale Automotive Wind Tunnel

A new full-scale automotive aerodynamics wind tunnel has been constructed and placed in operation at the General Motors Technical Center. Tunnel performance and flow quality specifications have been met through appropriate choices of design criteria, construction techniques, and inspection procedures. Test section size, two balances, and a boundary layer suction system provide a broad range of full-size and reduced-scale model test capability. Test support, operational and engineering environments, and equipment have been specifically tailored for automotive aerodynamics requirements.
