FIELD: shipbuilding. SUBSTANCE: mounted in through radial bores 5 of propeller hub 6 by means of split bush 7 and needle rollers 11 are blades 1 provided with flanges 2 and trunnion 3 with bearing bead 4. Stops of flanges 2 are mounted for turning in cuts of split bush 7. When this propeller is mounted on hopped-up engine, hydrodynamic resistance of ship's hull is reduced, thus reducing consumption of fuel. EFFECT: reduced hydrodynamic resistance of ship's hull and reduced consumption of fuel. 3 dwg
