Advantages: reduced displacement
Disadvantages: high requirements for hull materials
Introduction——
A single-shell submarine is a submarine with only one shell. Early submarines They are all single-hull submarines. They have only one pressure-resistant hull, and the main ballast water tank is arranged inside the pressure-resistant hull. A single-hull submarine only relies on one shell to withstand seawater pressure and maintain the air pressure inside the boat. Therefore, it must be pressure-resistant and is usually made of high-strength steel. Inside the pressure-resistant shell, command positions, weapons, equipment, devices, various systems and crew living facilities are arranged to ensure the normal work, life and combat of the crew.
The advantages of single-hull submarines are that they can reduce displacement, increase speed, simplify shipbuilding processes, and reduce manufacturing costs. The disadvantage is that single-hull submarines have high requirements for hull materials. At the same time, the safety of the hull is poor. Once it is subject to shock, impact, etc., the pressure-resistant hull is easily damaged. However, with the advancement of material technology and fluid mechanics, single hulls can withstand deep water pressure and maintain shape and internal pressure. Therefore, after World War II, the submarine side tests of the United States and other Western countries began to shift to a comprehensive single hull design.
Although Western submarines are called single-shell structures, in fact, most single-shell submarines are not complete single-shell submarines because a "light shell" is added to the bow and stern of the submarine. .
