RESCUE COMPARTMENT OF THE SUBMARINE Russian patent published in 2023 - IPC B63G8/40 B63C9/00 

FIELD: emergency submarines.

SUBSTANCE: invention relates to means of collective rescue of personnel in emergency submarines. The rescue compartment of a submarine is its bow compartment with a spherical aft - rear bulkhead, equally strong with a strong hull. Spherical aft - the rear bulkhead is connected to the same convex spherical bulkhead of the second compartment of the main hull of the submarine using an equal-strength short cylindrical insert, the diameter of which is less than the diameter of the pressure hull of the submarine, equipped with a passage hatch with bulkhead doors for moving personnel between compartments, and also serving to accommodate inter-compartment pipelines and cable routes. The cylindrical insert consists of two cylinders, which are welded on the outside to a spherical bulkhead by one base, each of its own compartment, and by the second base are connected to each other by a sealed shutter, inside which a shaped charge of an explosive is mounted along its perimeter, which is undermined in the event of an accident, the power of which enough to separate the cylinders of the cylindrical insert and either break the inter-compartment pipelines and cable routes, or, if they are made detachable, their separation, with the separation, in case of explosion, of the rescue compartment from the main body of the submarine, its ascent to the surface of the sea with the personnel of the submarine, placed in the rescue compartment.

EFFECT: increase in the number and reduction in the time of rescue of submariners in case of submarine flooding.
