METHOD OF BREAKING ICE COVER

摘要

FIELD: ice-breaking jobs. SUBSTANCE: flexural gravitational waves 3 are excited under ice 1 during motion of ship 2 at resonance speed. After excitation of resonance flexural gravitational waves, speed of ship 2 is reduced and she starts running at resonance speed again at moment first crest 4 of wave reaches conning tower at simultaneous putting fairwater diving planes 7 of ship 2 to angles of attack from 0-90 deg and from 90-0 deg at frequency of flexural gravitational waves. EFFECT: increased height of ice breaking wave. 1 dwg
