ABSTRACT:
A steering system is provided for a hydrodynamically shaped vehicle having a nose end, a tail end, and forward propulsion. The steering system includes an internal supply of drag-reducing medium, at least one ejector ring positioned adjacent a nose end of the vehicle, and a plurality of ejector sections formed in the at least one ejector ring. Each ejector section includes an opening arrangement for ejecting drag-reducing medium to an external surface of the vehicle. A control unit selectively supplies drag-reducing medium to at least one of the plurality of ejector sections. The drag-reducing medium ejected from selected ejector sections causes a reduced-drag surface on said vehicle body and an increased speed thereof relative to a remainder of the vehicle body and thereby imparting a directional motion to the vehicle in the form of pitch and/or yaw.
