METHOD FOR BREAKING THE ICE COVER Russian patent published in 2023 - IPC B63B35/08 

FIELD: marine navigation.

SUBSTANCE: navigation in ice conditions, in particular underwater vessels, floating in conditions of continuous ice cover and destroying it by the resonance method. When it is implemented during the movement of the vessel, the outboard water is pumped into the vessel using a pump located inside the vessel in the water flow channel, while the water intake part of the channel is located in the upper part of the ship's fore plating at the location of the foot of the bending gravity wave, and the channel outlet - at the aft end. The flow of water leaving the channel is directed under the maximum peak of the bending gravity waves.

EFFECT: increased efficiency of ice cover destruction.
