Abstract:
1. A device for reducing aerodynamic resistance of a vehicle, having a generally rectangular body with a front, a rear, a bottom, and sides disposed above rear wheels, which positions the rectangular body a predetermined position above a ground surface, the device comprising: a plurality of load bearing struts of a predetermined size attached to the bottom of the rectangular body adjacent the sides thereof; a plurality of opposed flat sheets, front opposed flat sheets disposed toward the front of the rectangular body, intermediate opposed flat sheets disposed behind the front opposed flat sheets, and rear opposed flat sheets disposed toward the rear of the rectangular body, each having a top edge disposed adjacent the bottom and side of the rectangular body, a lower edge disposed at a predetermined height above the ground surface and below the bottom of the rectangular body, and fastened to the load bearing struts; and a plurality of angled flaps fastened adjacent the lower edges of the intermediate opposed flat sheets and rear opposed flat sheets, each angled flap forming an obtuse angle with respect to each attached opposed flat sheet, extending inwardly with respect to the sides of the rectangular body, and extending to a predetermined height above the ground surface; whereby the intermediate opposed flat sheets and rear opposed flat sheets are stiffened by the angled flaps, which flex toward the generally rectangular body if struck by protrusions on the ground surface to resist damage; so that airflow is directed around the rear wheels reducing the aerodynamic resistance of the vehicle when moving.
