METHOD OF EMERGENCY SURFACING OF SUBMARINE IN CASE OF EXPLOSION OR FIRE RESULTING IN LOSS OF BUOYANCY Russian patent published in 2005 - IPC

FIELD: submarine building; technology of emergency surfacing of submarine in case of explosion or fire resulting in loss of buoyancy.

SUBSTANCE: proposed method includes charging the additional inflatable flexible reservoirs which are installed in the vicinity of aft compartment on the outside of hull. Emergency blowing of group of aft ballast tanks together with emergency charging of additional inflatable flexible reservoirs is effected automatically by signals of sensors rated at excess of permissible shock loads on hull or equipment or by signals of sensor operating at temperature exceeding permissible level. Number of additional inflatable flexible reservoirs and their volume shall be determined by calculations so that total lifting force of these reservoirs and group of aft ballast tank exceeds displacement of submarine.

EFFECT: enhanced reliability and efficiency for rescue of submarine personnel.
