FIELD: shipbuilding; submarine ships running under ice conditions and breaking ice cover by resonance method at surfacing in compact ice. ^ SUBSTANCE: proposed method consists in excitation of flexural gravitational waves during ship's motion under ice at resonance speed. During motion of ship, electromagnetic force of opposite direction as compared with ship's motion is created on her upper surface in aft extremity where crest of flexural gravitational wave is most likely to occur. ^ EFFECT: enhanced efficiency of breaking ice cover. ^ 1 dwg |
