FIELD: shipbuilding; water-jet propulsion units with full head water scoops. SUBSTANCE: proposed water scoop has flow- through pipe line with cylinders mounted rotatably inside it; axes of these cylinders are perpendicular to ship s CL. Cylinders are kinematically linked in pairs with closed flexible tape provided with artificial roughness. Located before lower cylinder of pair is flow divider and flow shifter is located after upper cylinder of pair. EFFECT: increased thrust of ship; enhanced efficiency of water-jet propeller. 1 dwg
