  • Patent number: 12110066
    Abstract: Aerodynamic fairing devices divert rising headwinds lifted over the top of a truck more laterally outwards to reduce vehicle drag. Embodiments include a truck cab roof mounted fairing, a streamlined truck cab roof, a fairing visor disposed on either cab roof fairing or on a streamlined truck cab roof, and a forwardly open-box sidewall assembly disposed on an upper portion of the front wall of a cargo box of a truck or semitrailer.

  • Patent number: 11814112
    Abstract: 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.

    Inventor: Garth L. Magee
  • Patent number: 11618512
    Abstract: An inwardly disposed vehicle skirt panel assembly disposed laterally inset toward the longitudinal centerline of the vehicle. The vehicle skirt panel assembly is suspended underneath a rearward body component of a truck or semitrailer, extending forwards in front of a rearward wheel assembly. The vehicle skirt panel assembly stabilizes otherwise laterally displaced air passing under the central portion of the moving vehicle, further increasing the effective air pressure developed immediately behind the vehicle. Maintaining air generally static while passing under the vehicle increases the effective pressure developed immediately behind the vehicle to reduce drag thereon.

  • Patent number: 9766153
    Abstract: 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 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 ground contact with the wheels of the vehicle.
