METHOD OF ICE COVER BREAKAGE Russian patent published in 2002 - IPC

FIELD: ice breaking operations. SUBSTANCE: essence of the invention consists in that submarine vessel 2 excites flexural-gravitational waves 3 in ice 1 when vessel moves at run-away speed. After excitation of resonance flexural-gravitational waves 3 imparted to vessel 2, for instance, with the help of compensating tank 4 are vertical vibrations and vessel continues its way at rising speed over path 5 equidistant to profile of excited flexural-gravitational waves 3. EFFECT: higher efficiency of action onto ice cover. 1 dwg
