Aerodynamic Trailer Systems Ltd. (ATS) of Auburn, Ohio, has developed a new product that fits on commercial trailer doors to provide a more aerodynamic shape to the rear of the trailer. The object is a “Green Technology” to reduce emissions by improving fuel efficiency of over-the-road trucks. The product, a boattail, is an aerodynamic device that reduces drag caused by air flowing in a random, turbulent manner around the rear of a commercial trailer. It effectively changes the flat surface of the rear doors to a curvilinear shape.

The design, developed by Aerodynamic Trailer Systems, is an inflatable boattail constructed from a heavy-duty flexible polymer material that automatically inflates and deflates by means of a blower and valving system at pre-set highway speeds. The deflated position overcomes a design challenge by allowing the rear doors to be fully opened for loading freight.
