FIELD: shipbuilding and marine engineering; design of pressure hulls of submersible vehicles, containers and other underwater structures. SUBSTANCE: brittle material is placed in space bounded by metal facings by pouring its molten mass from which brittle material is formed upon cooling into mould. Metal facings located between this mould and mass being poured follow the surface of envelope of pressure hull and possess increased coefficient of thermal expansion as compared with coefficient of thermal expansion of bittle material. Before pouring the mass. facing are heated to temperature sufficient to ensure reliable joint with brittle material. Casting hole is closed by metal facing part which is heated (before pouring the mass into mould) to a temperature sufficient to ensure reliable joint with brittle material, after which it is tightly pressed to molten mass. To manufacture large-size envelope of pressure hull, molten mass is pored in several portions; in between pouring procedures, mould and metal facings are increased. To enhance rigidly and stability of pressure hull envelope, metal facing are made with frame or with corrugations which form frames and stringers after filling with molten mass and cooling. EFFECT: enhanced reliability. 5 cl, 1 dwg
