FIELD: shipbuilding, in particular, water-jet propellers of high-speed ships and other floating means. ^ SUBSTANCE: the insert-water conduit has an inlet and an outlet, as well as at least one streamlined body made in the form of a lattice wing, and the wings making up the lattice have a controllable angle of attack and are positioned in planes perpendicular to the diametric plane of the ship, the lower wing of the lattice is installed at the after plating of the insert-water conduit, and the upper one above-at the bow plating, a plate-like interceptor is installed along the rear edge of the wings on the side of the lower surface, and the shape of the surface of the insert inner plating corresponds to the surface of flow of real liquid flowing around the bodies contained in the insert. ^ EFFECT: obtained an additional thrust to the stop of the water-jet propeller, thereby increasing the speed of motion or reducing the fuel consumption, enhanced efficiency of the propeller to the value close to the efficiency of the screw propeller. ^ 2 dwg |
