FIELD: shipbuilding; submerged vessels breaking ice cover by resonance method. SUBSTANCE: submerged vessel runs ice at resonance speed corresponding to maximum amplitude of flexural gravitational waves which is determined and maintained depending on maximum deviation of ultrasonic signal radiated from ice cover. EFFECT: enhanced efficiency due to enhanced accuracy of determination of resonance speed. 2 cl, 1 dwg
