Abstract

A dual-strake assembly can be coupled to the underbody of the vehicle in order to maximize the downforce-to-drag ratio, thereby enhancing the vehicle aerodynamic efficiency. The dual-strake assembly includes a first strake and a second strake having different curvatures. The second strake has a chord length. Each of the first and second strakes has a first edge and a second edge opposite the first edge. The first edges of the first and second strakes are spaced apart from each other so as to define a gap, which has a gap distance measured from the first edge of the first strake to the first edge of the second strake. The gap distance is equal to or less than twenty-five percent of the chord length. The camber of the first strake is less than the camber of the second strake.
