FIELD: shipbuilding; breaking ice cover by resonance method with the aid of hovercraft.
SUBSTANCE: prior to starting ice breaking jobs, areas of ice cover of minimum strength are found and hovercraft runs over these areas at resonance speed breaking ice cover; then, hovercraft starts running over areas of ice cover of higher strength. Areas of ice cover of high strength are found with the aid of ultrasonic flaw detector showing thickness and structure of ice.
EFFECT: enhanced efficiency of breaking ice cover.
