METHOD FOR SHEET ICE BREAKING Russian patent published in 2016 - IPC B63B35/08 B63B35/10 E02B15/02 B60V3/06 

Abstract RU 2603422 C1

FIELD: ice-technology.

SUBSTANCE: invention relates to ice-technology, particularly to ice breaking. Method of ice breaking is performed by air-cushion ship during its movement over ice with resonance speed. After excitation in ice of resonance flexural-gravity waves ship, within moving behind it with resonance speed first wave trough is imparted additional periodic reciprocating movements in direction of its movement with frequency of resonance flexural-gravity waves. Movements are provided maximum within wave troughs, that is equal to half their length, and ship is imparted lengthwise rolling with frequency of resonance flexural-gravity waves.

EFFECT: technical result consists in improvement of efficiency of ice breaking.
