The objective of this research was to initiate the development of a design procedure to optimize the shape of a drag reducing device to obtain a significant drag reduction on the rear end of a trailer of a tractor-trailer rig. To meet this objective, four wind tunnel experiments were conducted. An optimized shape has not been determined as of yet; however, it was found that the aerodynamic drag could be reduced as much as 17.4 percent, and that there are several important parameters that influence the drag reduction, such as: device length, device edge curvature, and the device-to-trailer attachment angles.
