ABSTRACT:
A device for reducing air drag on highway vehicles includes a fabric enclosure mounted on the rear end of the vehicle which is self-inflated by a pressure differential between the outer and inner surfaces of the fabric enclosure created by the forward movement of the vehicle. The enclosure includes an inner flat fabric web and an outer shaped fabric web in a frame which is removably secured to the vehicle by mounting pins extending through hingedly mounted angles. The device may also be mounted on the rear of the forward trailer of a tandem trailer or behind the cab of a tractor-trailer having a cab mounted fairing device.
