FIELD: shipbuilding; increase of load-carrying capacity of impact-resistant shells( taper or cylindrical drums open at ends which are used as blanks for manufacture of articles from sheet materials). SUBSTANCE: second shell is fitted on the outside of first shell; both shells are connected by means of flexible members maintaining even clearance between them. EFFECT: enhanced resistance to shock waves and local loads.
