FIELD: shipbuilding.
SUBSTANCE: invention relates to shipbuilding, namely, to versions of propulsors. In three versions propeller screw comprises hub with blades. In the first version, the shape of the screw blades has the shape of pipe fragments bent around the hub at an angle to its axis. In the second version, the shape of the screw blades has the form of semi-rings bent along the spiral around the hub by the concave side towards the screw rotation side, and upper edges of blades lie on surface of imaginary cylinder with radius similar to that of propeller. In the third version, the shape of the screw blades has the shape of pipe fragments bent around the hub, and with edges parallel to the screw axis.
EFFECT: higher screw thrust.
