ABSTRACT |
Coast-down tests have been performed on a box-shaped ground vehicle used to simulate the aerodynamic drag of high volum transports such as delivery vans, motor homes and trucks. The results of these tests define the reduction in aerodynamic drag that can be obtained by the addition of either a full boattail or a trucated boattail to an otherwise blunt-based vehicle.
