ABSTRACT:
Devices, and associative methods, of creating drag on a transport vehicle are disclosed. Drag creation devices are comprised of a slipstream control device and a striking surface device. The slipstream control device attaches to a truck of a transport assembly. The slipstream control device has at least one moveable part which provides for transfer of the slipstream control device between a slipstream streamlining orientation and a slipstream redirecting orientation. The slipstream control device acts upon a slipstream created by movement of the transport assembly during a forward advance along a highway. The striking surface device may be attached to the truck or to a trailer attached to the truck. The striking surface device has an impingement surface which provides for impingement of a portion of the slipstream redirected by the slipstream control device while in the slipstream redirecting orientation. The impingement creates the desired drag upon the transport vehicle. Optionally, the striking surface device may be moveable between a free flow configuration and an impingement configuration.
