Abstract
An air flow management system for a rear of a cargo trailer, box car, bus, van, truck, or similar vehicle, having a shaped skin in a three-dimensional surface such as a vertical half of a gas bag envelope of a hot air balloon, and an attachment bracket for the shaped skin to a rear side of the cargo vehicle to reshape and improve the aerodynamics of a vertical planar rear surface of the cargo vehicle by controlling the decompression and expansion of air flow around the rear of the vehicle, which is especially useful for over-the-road cargo trailers having side skirts.
