Claim:
1. A drag-reducing apparatus for a cargo container, the cargo container defining a top surface, a first side surface having a first rear door attached thereto by at least one first hinge, and a second side surface having a second rear door attached thereto by at least one second hinge, the apparatus comprising: a first flexible airfoil comprising a first side edge and one or more first exit holes; a plurality of first fasteners adapted to join the first side edge of the first flexible airfoil to the first side surface adjacent the first hinge to define a first air inlet between the first flexible airfoil and the first side surface; a second flexible airfoil comprising a second side edge and one or more second exit holes; and a plurality of second fasteners adapted to join the second side edge of the second flexible airfoil to the second side surface adjacent the second hinge to define a second air inlet between the second flexible airfoil and the second side surface, wherein the first air inlet permits air flow along the first side surface into the first flexible airfoil to inflate the first airfoil into a first deployed position and the first exit holes permit the air received from the first air inlet to exit the first airfoil when the cargo container is moved in a direction away from the first flexible airfoil; and wherein the second air inlet permits air flow along the second side surface into the second flexible airfoil to inflate the second airfoil into a second deployed position and the second exit holes permit the air received from the second air inlet to exit the second airfoil when the cargo container is moved in a direction away from the second flexible airfoil.
