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.
Claims11
A vehicle, comprising:
- a vehicle body including an underbody;
- at least one dual-strake assembly coupled to the underbody, wherein the at least one dual-strake assembly includes:
- a first strake coupled to the underbody, wherein the first strake has a first camber;
- and
- a second strake coupled to the underbody, wherein the second strake has a second camber, and the first camber is less than the second camber;
- and
- wherein the at least one dual-strake assembly includes a first set of dual-strake assemblies and a second set of dual-strake assemblies, and the first set of dual-strake assemblies and the second set of dual-strake assemblies are equidistantly spaced from each other.
