DEVICE FOR BREAKING DOWN ICE COVER Russian patent published in 2019 - IPC B63B35/08 

FIELD: ship building.

SUBSTANCE: invention relates to shipbuilding, particularly to submarine vehicles which break up ice cover using a resonance method. Proposed device for the destruction of the ice cover, which is an underwater vessel that can move under the ice at a resonant speed and excite resonant flexural-gravity waves. Surface turbulators of the boundary layer in the form of belts are installed on the surface of the vessel with the ability to periodically advance, and then embed in the hull with a frequency equal to the frequency of resonant flexural-gravity waves, and be in the extended or recessed positions for a time equal to half the period of these waves.

EFFECT: increased efficiency of ice destruction is achieved.
