METHOD OF BREAKING ICE COVER FOR BATHYSCAPH SURFACING Russian patent published in 2017 - IPC B63B35/12 B63G8/00 

FIELD: transportation.

SUBSTANCE: ice cover breaking method for the bathyscaph surfacing is proposed, in which the bathyscaphe floats against the deckhouse stop into the ice, the rods with electrodes are pulled out from the body against it stop into the ice, the rods are filled with the seawater and heated by the electric heating elements, located inside the hollow side wall of the rod, after melting in the ice thickness the slots, charge the capacitive storage installed inside the hull to the rated depth, and then discharge the capacitive storage, initiating the electric charge in the spark spacer between the inner surface of the end part of the rod and the electrode end, after that the rods with the electrodes are returned into the initial position, increase the positive floatability up to the design value, breaking the weakened ice cover with the bathyscaph hull and move the bathyscaph deckhouse into the surface position.

EFFECT: reduction of the mechanical impact of the cracked ice on the hull, which increases the safety level, when surfacing the bathyscaph.
