DEVICE FOR DESTRUCTION OF ICE COVER Russian patent published in 2020 - IPC B63B35/08 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding, in particular to underwater ships, breaking ice cover by resonant flexural-gravity waves. Device for breaking the ice cover consists of an underwater vessel capable of moving under the ice at a resonant speed. On upper surface of hull of ship in fore part of it under the first cavity excited by ship of flexural-gravity waves is periodically installed, i.e. extends from ship hull, wedge cavitator with frequency of resonant flexural-gravity waves, time of cavitator in extended position should be equal to half of their period.

EFFECT: enabling increase in the ice cover destruction efficiency.
