FIELD: shipbuilding; ice-breaking submarine vessels cleaning water basins from ice cover. ^ SUBSTANCE: proposed device includes submarine vessel exciting resonance flexural gravitational waves while running under ice at resonance speed. Upper deck of ship may be deformed to state of mirror image of flexural gravitational waves excited by ship by means of drives mounted under it and actuated by ultrasonic sensors which are mounted on deck for measuring the vertical distance between upper deck and lower surface of ice cover. ^ EFFECT: enhanced efficiency of ice breaking. ^ 1 dwg |
