DEVICE TO CONVERT SEA CURRENT FORCE INTO SHIP PROPULSION FORCE Russian patent published in 2011 - IPC B63H19/02 

FIELD: transport.

SUBSTANCE: invention relates to ship building and pertains to devices to convert sea current forces into ship propulsion forces. Proposed device comprises ship hull, several hollow annular cylinders that make rotors arranged to rotate about vertical axes, rotor electric drive, appliance to reverse rotor rotation, power source, a storage battery, and sip propeller screw electric drive. Ship hull is provided with several crosswise through channels to accommodate rotors arranged so that their lengthwise axes are aligned with ship lengthwise axis, while their crosswise axes are shifted from through channel crosswise axes by magnitude equal to half the rotor diametre. Opening between through chamber sidewall and rotor on bow side is smaller than that on ship stern side. Crosswise through channel cross section may have rectangular shape with its height exceeding its width.

EFFECT: simplified design, access to operating components for servicing, reduced power consumption.
