US 10,556,629 - INNER WHEEL SKIRT REDUCING VEHICLE DRAG

An inner wheel skirt panel centrally located under the body of a vehicle reduces overall vehicle drag by inhibiting air from otherwise being displaced laterally inward by the passing wheels of the moving vehicle. Maintaining air to remain generally static while passing under the vehicle through the central open-space between the wheels increases the effective air pressure developed immediately behind the vehicle to reduce overall drag developed between the front and rear of the vehicle.

Proven performance, road tested by MVT Solutions demonstrated improved fuel economy in Pecos, Texas, 2018. Inventor seeks partner in developing this proven cost-effective drag-reducing technology. This technology has potential application for a variety of vehicles other than trucks and semitrailers, including automotive race cars.

Patent

US 10,538,280 - WHEEL FAIRING REDUCING VEHICLE DRAG

‘Wheel Fairing Reducing Vehicle Drag’ teaches that minimally shielding only the faster-moving upper wheel can maximize vehicle aerodynamic efficiency, especially when facing punishing headwinds.  “Previous aerodynamic fenders were simply too large, inducing too much drag by extending too far downward, thereby negating the dramatic performance gains achievable from efficiently shielding only the most critical drag-inducing uppermost wheel,” said Inventor Garth Magee, founder of NULL WINDS Technology.

“A small upper wheel fairing eliminates the highly magnified drag on the faster-moving upper wheel, enabling the use of wider, more stable tires without significant loss in propulsive efficiency or crosswind stability.  The aero gains are so significant that most road bike cyclists experience a remarkable 10-20 percent increase in speed when facing even moderately strong headwinds.” 

The invention teaches that exposed upper wheels needlessly increase vehicle drag, since winds on the uppermost wheel often exceed twice the vehicle speed.  (Faster winds induce far more drag, especially under headwind conditions.)  Thus, all open wheel vehicles are needlessly inefficient—especially vehicles having wider tires—being inherently handicapped against headwinds by the exposed upper wheel. 

AERODEFENDER™ has been extensively tested with proven performance.  The invention also teaches that faster vehicles gain the most, thereby having application for automotive vehicles and racecars.  And shielding the upper wheel also increases lateral steering traction by reducing the drag-induced ground slip force, thereby noticeably enhancing stability at speed. 

Evaluated and currently endorsed by Hawaii Ironman winner, Olympian and road cycling legend John Howard (www.johnhowardsports.com), the invention provides a new standard for minimizing drag on bicycles, as well as for other open-wheel vehicles, from motorcycles to racecars.  While noticeably reducing the pedaling effort required against headwinds, the invention can also extend battery range on electric bicycles in windy conditions, or when simply cycling generally above 15 mph under static conditions.

US 9,878,745 - UPPER WHEEL FAIRING REDUCING CRITICAL VEHICLE DRAG

A method and apparatus for shielding critical faster-moving upper wheel surfaces from headwinds reduces vehicle propulsive counterforces needed to countervail mechanically magnified upper wheel drag forces combined with drag forces on the apparatus itself.  The apparatus includes various upper wheel fairings of FIGS. 1 – 6.  Each fairing shields a critical primary vehicle-drag-inducing upper wheel surface from headwinds otherwise impinging thereon. (All AERODEFENDER™ Wheel Fairing products to be covered by this patent.)

US 9,290,041 - STREAMLINED TAILFIN FOR BICYCLE WHEEL SPOKE

A streamlined tailfin rotatably attached to a bicycle wheel spoke reduces drag by swiveling as a wind vane in both headwinds and crosswinds. (All SPOKE FIN™ spoke tailfin and AEROCROSS™ wheel products are covered by this patent.)

Patent

US 9,766,153 - MEASURING VEHICLE DRAG IN A WIND TUNNEL

A method and apparatus for measuring the propulsive power required to overcome drag forces on a vehicle mounted within a wind tunnel.  The apparatus includes a running belt platform driven by a dynamometer and supporting the vehicle, to be vehicle placed inside a wind tunnel and controlled by a closed-loop servo control system, which maintains the vehicle centered on the running belt under varying operating speeds and headwind conditions.  The power dissipated in drag is measured as the power transferred through groundward contact with the wheels of the vehicle.
