METHOD OF BREAKING ICE COVER

摘要

FIELD: ice-breaking jobs. SUBSTANCE: hovercraft 2 runs on ice cover 1 exciting resonance flexural gravitational waves 3, thus forming aerodynamic lift force directed downward by turning horizontal plane 5 mounted preliminarily on upper deck 4 through negative angle of attack (position 6) towards incoming air flow. Angle of attack is changed regularly at frequency of said waves. EFFECT: increased thickness of broken ice. 1 dwg
