Abstract

An apparatus is provided for reducing aerodynamic drag experienced by an over- the-road vehicle while underway. A frame assembly including a fastening fixture couples the apparatus to the vehicle, and a first airfoil including a first outward air deflecting surface deflects a portion of the airflow directed toward a first tire laterally outward toward an externally exposed side of the first tire. A second airfoil including a second outward air deflecting surface deflects a portion of the airflow directed toward a second tire laterally outward toward an externally exposed side of the second tire. The first and second airfoils are spaced laterally apart from each other when coupled to the vehicle by the frame assembly to define an aperture between the first and second airfoils through which at least a portion of the airflow directed toward the axle assembly is to pass while the vehicle is underway.
