Abstract
The invention comprises an inflatable bag mounted on each of the rear trailer doors of a standard tractor-trailer unit. The optimum aerodynamic shape of the bags with stable flat external surfaces for air to pass over is created by a series of internal cords extending horizontally in a radial array from the medial edge of the base of each bag to its corresponding lateral surface, and vertically form the top to the bottom surfaces of each bag.
