FIELD: transportation.
SUBSTANCE: propeller incorporates curved blades fitted radially on the running screw hub. A guide block representing a curved-base radially fitted blades is coaxially arranged behind the propeller screw, the blades directing the flow created by the said screw solely towards one side from the screw. The guide block base is attached to the vehicle. The said base represents a ring with the wing-shape blades attached thereto, the blades create a force acting in direction of the screw thrust and brought about by a direct impact of air or water flow on the blades. The ambient medium flow is forced rectilinearly along the propeller axis.
EFFECT: increased propeller thrust.
