METHOD OF BREAKING ICE COVER Russian patent published in 2006 - IPC B63B35/08 E02B15/02 B63G8/00 

FIELD: technology of breaking ice cover and cleaning of water basins; surfacing of submarines under ice conditions.

SUBSTANCE: proposed method of breaking ice cover by submarine vessel consists in excitation of flexural gravitational waves in ice cover when vessel is running under ice at resonance speed. In the course of motion of vessel, width of wake current formed in aft extremity of vessel is increased, thus increasing resistance of hull lines and wave resistance, i.e. height of waves being excited.

EFFECT: enhanced efficiency of breaking ice cover.
