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

FIELD: icebreaking works.

SUBSTANCE: method is proposed for destruction of ice cover by submarine by excitation of flexural-gravity waves in ice under its motion under ice at resonant speed, consisting in the fact that at destruction of ice two ships are simultaneously used, which are moving with wake system at minimum safe from each other distance and on the same deepening, note here that rear ship speed is first reduced and then increased to resonant at the moment of location above it of bottom of flexural-gravity waves excited by front ship, after that its deepening is increased by value equal to diameter of front ship hull.

EFFECT: invention is aimed at improvement of efficiency of ice destruction.
