ABSTRACT:
In order to increase energy efficiency by reducing the drag experienced by bodies moving through a fluid medium, such as tractor-trailers, structure is incorporated in the rear surface or panel of the bodies. The structure is implemented with a multiplicity of cavities or a multiplicity of protruding regions. The cavities or protruding regions each comprise only a small portion of the total area of the rear surface and the depth or extension dimension, relative to the rear surface or panel, is small. In the case of a tractor-trailer, the rear surface structure permits convenient access to the interior of the vehicle and can be incorporated in either a rear door assembly or in a sliding rear panel assembly. The drag reduction benefits are achieved not only when the body is a tractor-trailer but also in the case of all types of land vehicles, water craft, aircraft, projectiles and the like which have a relatively flat rear surface.
