ABSTRACT:
A system for reducing skin friction drag includes a user-controlled drag reducing substance and components for introducing the substance at or near the surface of the object for which skin friction drag is desired. In a fluid injection system embodiment, a pressurized injectant source supplies an injectant, an injector device injects the injectant near the surface of the object for which drag reduction is desired, a hose or conduit directs flow of the pressurized fluid from the source to the injector device and a control device enables a user to control the flow.
