1. An aerodynamic device for reducing drag on a ground vehicle, comprising:
- a first pair of rigid panels attached to the left side of the bottom surface of the vehicle and extending downward from the vehicle, including an outer panel substantially coplanar with the left surface of the vehicle and an inner panel located inboard of the outer panel; and
a second pair of rigid panels attached to the right side of the bottom surface of the vehicle and extending downward from the vehicle, including an outer panel substantially coplanar with the right surface of the vehicle and an inner panel located inboard of the outer panel.

Abstract
A device for the reduction of aerodynamic drag and for improved performance and stability of ground vehicles by reducing the mass and velocity of the flow passing under a vehicle is described. The device is particularly suited for a tractor-trailer truck system that includes a motorized lead vehicle pulling one or more non-motorized vehicles. The device is designed to control the flow from entering the undercarriage region from the side of a trailer of a tractor-trailer truck system.
