FIELD: shipbuilding; technology of enhancing resistance of submersible vehicles to impact wave loads. SUBSTANCE: hull of submersible vehicle, mainly submarine, is made from two envelopes with strength members between them. External envelope is in communication with outside water medium; space between envelopes is filled with flexible envelopes. Inner cavity of flexible envelopes is under action of gas pressure. EFFECT: reduction of load on submarine hull when she is acted on by impact stepped load.
