FIELD: shipbuilding; designing amphibian hovercraft for breaking icer cover by resonance method. SUBSTANCE: proposed ice-breaking hovercraft has hull with flexible guard and superstructure. Mounted in hull in one vertical with its center of mass is vertical extensible plunger with ice bore inside it; this plunger performs vertical motion at frequency of resonance flexural gravitational waves in ice cover. EFFECT: enhanced efficiency of breaking ice cover by resonance method. 2 dwg
