ELECTROMAGNET PROPELLER Russian patent published in 2009 - IPC B63H11/02 H02K44/00 

FIELD: shipbuilding.

SUBSTANCE: invention is related to propellers and may be used at marine vessels. Electromagnet propeller comprises set of energy accumulators, switching device, body with channel for inlet and outlet of water, in which main electrodes are installed for current generation in electric field, covering section of specified channel, and device for generation of magnetic field oriented perpendicularly to electric field, to create main Lorentz force. In working channel of propeller there is at least one pair of additional electrodes installed as insulated from the main electrodes, with the possibility to provide for electric breakdown of water and development of additional Lorentz force that matches the main one in direction. At the same time switching device provides for connection of energy accumulators to additional electrodes.

EFFECT: increased efficiency factor of proposed propeller due to artificial increase of water electric conductivity.
