This slab-sided aluminum body was mounted over a standard van during research in applying aerodynamic drag reduction techniques to ground vehicles conducted at NASA’s Dryden Flight Research Center in the late 1970s and early 1980s. Felt tufts mounted on the sides, top and semi-boat tail rear of the modified body clearly show the airflow over the structure.1981NASA photo
