FIELD: transport.
SUBSTANCE: device of manoeuvrable submarine screw-propeller includes submarine body, driving shaft, screw propeller on telescopic shaft with hub and with curved ends of blades, circular cavity, sound-proofing steering tube. The screw propeller is installed on brackets in tube cavity and pivotally connected with driving shaft. Inner and outer surfaces of tube are covered with viscoelastic damping material, with cavity covering with wear-resistant material layer. End of the tube is provided with flange. Bodies of four hydrodraulic (pneumatical) cylinders-manipulators are rigidly fixed along flange perimetre at equal distances. Rods of cylinders-manipulators are pivotally attached to disk eccentrics. Platform with movably attached eccentrics is installed on body. Driving shaft of submarine passes through passageway in the centre of the platform.
EFFECT: higher submarine maneuverability and suppression of noise from screw propellers.
