Abstract
The dynamically adjustable airfoil system for road vehicles includes a pair of airfoils having their respective inner ends pivotally mounted to a central, vertical base on the rear of a road vehicle. An airfoil lift assembly is coupled to an outer end of each airfoil and to a rear wheel suspension system to facilitate dynamic adjustable positioning of the airfoils in response to movements of the suspension system. A split flap is pivotally mounted to each airfoil. A split flap actuator assembly is mounted inside each airfoil and coupled to a corresponding split flap to selectively and independently open or close the respective split flap. Opening of the split flap to various angles increases downforce exerted on the rear suspension system for improved performance. A controller controls deployment and angular disposition of the split flaps, depending on driving conditions.
