This photograph illustrates a standard passenger van modified at the Dryden Flight Research Center to investigate the aerodynamics of trucks. The resulting vehicle – re-fashioned with sheet metal – resembled a motor home, with rounded vertical corners on the vehicle's front and rear sections.

This photograph illustrates a standard passenger van modified at the Dryden Flight Research Center to investigate the aerodynamics of trucks. The resulting vehicle – re-fashioned with sheet metal – resembled a motor home, with rounded vertical corners on the vehicle’s front and rear sections. For subsequent tests, researchers installed a “boat tail” structure, shown in the photograph.February 18, 1981NASA Photo› Aerotruck Project Description
