FIELD: shipbuilding; propulsion systems.
SUBSTANCE: proposed propulsion system with submersible electric motor has autonomous body and reversible submersible electric motor whose stator is secured to body and rotor is provided with circular ring on inner side. Provision is also made for protective separators. Propulsion system has propeller whose blades are secured to inner surface of ring in form of cylinder or truncated cone. Shaft of rotor is simultaneously used shaft of propeller. Shaft is mounted in bearings fitted in struts secured on body from both sides from electric motor and/or on stator; propeller hub is rigidly connected with rotor shaft.
EFFECT: enhanced propulsive characteristics of ship; reduced level of noise in ship's spaces and in surrounding water medium.
