FIELD: ice-breaking jobs.
SUBSTANCE: submarine vessel (2) runs under ice (1) at resonance speed and resonance flexural gravitational waves (3) are excited in ice. During motion, poorly streamlined shape is imparted to vessel (2) by forming hydrodynamic eddies (8) in fore and extremities of vessel. Water sucked from area of minimum pressure for forming these eddies.
EFFECT: enhanced efficiency of ice breaking.
