ABSTRACT:
Aerodynamic drag reducing apparatus for mounting on the bluff, forward face of the trailing element of an over the road vehicle. The apparatus comprises a contoured member carried on the forward face and extending outwardly therefrom with its point of maximum extension substantially aligned for impingement by an air stream. The portion of the surface displaced above the point of maximum extension describes a perturbed paraboloid of revolution with the rearward portions of the apparatus describing three sides of rectangle for aerodynamic merging with the top and side edges of the trailing element.
