FIELD: ice-breaking jobs. SUBSTANCE: submarine vessel 2 moves under ice 1 at resonance speed exciting resonance flexural gravitational waves 3 under ice and air is fed to area of stern of ship 2 for forming air cavity 6 behind ship, after which ship is braked. Wake current 4 continuing its translational motion by inertia meets air cavity 6 and then obstacle in form of ship 2, thus causing building-up of increased pressure 7 in area of ship s stern. EFFECT: enhanced efficiency. 1 dwg
