FIELD: shipbuilding; hovercraft breaking ice cover by resonance method, namely by excitation of flexural gravitational waves. SUBSTANCE: during motion of ship, repeated passages of ship are performed over field of ice to be broken. Number of lanes thus formed is limited to avoid rise of trim by stern. Repeated passages are performed at critical speed. EFFECT: enhanced efficiency of ice breaking. 2 cl, 1 dwg
