METHOD OF BREAKING ICE COVER

摘要

shipbuilding; ships running in ice and breaking ice by resonance flexural gravitational waves. SUBSTANCE: submersible ship runs under ice at safe depth of submergence at speed ensuring continuous break of ice due to rarefaction on ship's hull. Speed is determined and maintained by minimum hydrostatic pressure with the aid of pressure pickup mounted in central portion of ship's hull. EFFECT: enhanced efficiency of breaking ice. 2 cl, 2 dwg
