20120104794 | BASE DRAG REDUCTION FOR ROAD VEHICLES AND 'AIRDROP' CARGO AIRCRAFT - Methods providing naturally driven routing of air bleed derived from the external air pressure field typically developed about a moving vehicle were conceived.

Low energy air bleed flow injected into the vehicle's separated afterbody region acts to replenish entrained base flow and its base drag reduction is thereby achieved. | 05-03-2012 |

20120175910 | SYSTEM AND METHOD FOR DRAG REDUCTION - A system and method for drag reduction allows thrust output, fuel efficiency or both to be maximized. Specifically, a rear portion of a body or motor vehicle may be modified to increase thrust output, fuel efficiency or both by creating a stagnation area, a suction inlet and a convex cusp area formed on the rear portion of the motor vehicle. Increasing the concavity or camber or sharpness of the radius of the stagnation area results in greater local pressure coefficient, which results in greater thrust output. The size and shape of the suction inlet and the convex cusp area will also have an effect on thrust output and fuel efficiency. A width and volume of an airplane fuselage may be increased. | 07-12-2012 |

20130181479 | VEHICLE TRAILER WITH IMPROVED AERODYNAMICS - Trailers, such as semi-trailers, having configurations that improve the aerodynamic efficiency thereof are provided. In some examples, aerodynamically configured trailers are provided that maintain standard cargo capacity. To improve the aerodynamic efficiency, the rearward end of the trailer in some embodiments include a downward cant or slope. In use, the rearward cant or slope reduces the low-pressure region that trails the end of the trailer, thereby reducing pressure drag. In accordance with another aspect, to accommodate loading and unloading of the downwardly canting or sloping trailer, examples of the trailers may also be equipped with “sliding trailer axle” and/or extended travel landing gear so as to allow the trailer to interface with standard loading dock heights as well as rampless ground loading/unloading. | 07-18-2013 |
20160039479 | WHEEL WELL REAR PORTION STRUCTURE - In a vehicle to which a wheel well rear portion structure has been applied, a curved portion of an upper wall of a guide portion bulges obliquely toward the vehicle lower side as seen in a side view and is connected to a discharge portion. An air flow flowing in a flow channel flows along the upper wall due to the Coanda effect, so in the air flow along the curved portion the flow component heading toward the vehicle rear side becomes larger. The flow direction of the air flow discharged from the discharge portion substantially coincides with the flow direction of an air flow flowing in the space under the body of the vehicle. In a state in which a drop in the flow speed of the air flow discharged from the discharge portion is controlled, the air flow can be caused to smoothly merge with the air flow. | 02-11-2016 |
