MARINE PROPULSIVE ARRANGEMENT WITH POWER ACCUMULATOR Russian patent published in 2014 - IPC B63H23/24 

FIELD: engines and pumps.

SUBSTANCE: invention relates to electrical drives designed to transfer power from primary thermal engine to propulsors. Proposed complex comprises thermal engine, first shaft, variator and second shaft whereat screw propeller is fitted. Said variator incorporates first unipolar generator and second unipolar generator, not engaged mechanically, and third unipolar machine fitted on hollow shaft rung in bearings or magnetic suspensions coaxially with first or second shaft. Power accumulation flywheel is fitted on the same shaft. RPM transducers are fitted on all shafts. Said transducers are connected with control system whereto excitation windings of unipolar machines are connected as well as thermal engine rpm control unit. Subject to control signals this machine runs in engine or generator mode while flywheel accumulates or outputs the accumulated power.

EFFECT: higher efficiency, decreased overall dimensions and weight, higher reliability.
