FIELD: ship building.SUBSTANCE: invention relates to shipbuilding, particularly to submarine vehicles which break up ice cover. Device for the destruction of the ice cover consisting of a submarine vessel equipped with an anchor is proposed, the diameter of the paws opening must be greater than the length of the cockpit, which secures the attachment of the vessel to the ice, ballast tanks are filled with outboard water to develop the negative buoyancy force sufficient to break the preset-depth ice. Point of the rope securing to the submarine should be aligned with the submarine displacement center. Under the ice cover, a pump is installed on the anchor line, capable of periodical sucking out of water from under ice with the frequency of resonant flexural-gravitational waves for a time equal to half of their period and with a flow rate at which a cavitation cavity will appear under the ice cover.EFFECT: technical result is to increase the thickness of the ice cover to be destroyed.1 cl, 1 dwg
