Patent attributes
A semi-trailer aerodynamic drag deflection assembly for reducing aerodynamic drag upon all surfaces of the semi-trailer includes a pair of interior walls positioned against a respective one of a pair of lateral surfaces of a semi-trailer. A plurality of vents is positioned from an inner surface to an outer surface of the interior wall. A pair of exterior walls is positioned against a respective one of the pair of interior walls. An outside surface of each of the exterior walls has a plurality of indents for deflecting wind An undercarriage has a pair of side walls with a storage being positioned between each of the side walls. Each of the side walls has a plurality of fins directing aerodynamic drag from the bottom surface of the semi-trailer into each of the vents of each of the interior walls. A pair of doors provides access to the storage of the undercarriage.
