Abstract RU 2425776 C1

FIELD: transport.

SUBSTANCE: proposed cylindrical shell of watertight hull from glass metal composite is made up of at least two different-diameter cylindrical shells from glass breakage lined by metal coat. Cylindrical shells are fitted one into another aligned and with annular clearance there between. Stiff annular shell from foamed glass is fitted in said annular clearance over entire length of cylindrical shell by synthesis of foamed glass directly in said clearance.

EFFECT: higher strength at invariable weight, required buoyancy with no extra buoyancy add-on.
