FIELD: transportation.
SUBSTANCE: ring nozzle for the propeller screw has a cylindrical shape with an increased width. The ring nozzle, in the set form, covers the propeller screw and the part of the fairing screw in such a way that the outlet diameter of the ring nozzle is partly overlapped by the fairing. The diameters of the inlet and outlet openings of the ring nozzle are equal.
EFFECT: increase the reactive tractive effort and prevent the propeller screw cavitating.
