| 20090256385 | VEHICLE WITH DRAG-REDUCING OUTER SURFACE - A vehicle with a drag-reducing outer surface. A method of reducing aerodynamic or hydrodynamic drag on a vehicle includes the steps of: providing an outer surface on a body of the vehicle, with the outer surface including spaced apart turbulence-inducing structures thereon. The structures cause boundary layer separation to be delayed along a length of the body, thereby reducing a drag coefficient of the body. A vehicle wrapping product for reducing aerodynamic or hydrodynamic drag on a vehicle includes an outer surface for applying onto an opaque portion of a body of the vehicle. The outer surface includes a plurality of structures which induce turbulence and thereby delay separation of a boundary layer along a length of the body, to thereby reduce a drag coefficient of the body. | 10-15-2009 |
