DEVICE FOR BREAKING DOWN ICE COVER Russian patent published in 2009 - IPC B63B35/08 

Abstract RU 2353540 C1

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding, particularly, to submarine, which break down ice cover using the resonance method. Device for breaking down of ice cover is a submarine, capable of moving under ice with resonance speed and generating resonance bending-gravitational waves. On the surface of the body of the vessel on its fore ends is installed a boundary layer trip in the form of devices, periodically inducing in the friction layer transverse secondary flow.

EFFECT: increase in the effectiveness of breaking down ice cover by reducing costs and generating resonance bending-gravitational waves with amplitude, enough for breaking down ice cover.
