What is the shape of a modern submarine?

The submarine's shape is not very powerful, or even very much like an ordinary ship. Its shape is called "teardrop" or "spindle", which reduces the resistance of underwater movement to ensure that the submarine has a good maneuverability, so that the submarine can swim far underwater. The first is to make sure that the submarine has good maneuverability, so that the submarine can swim fast and far underwater.

The submarine's shell has an inner shell, also known as the solid shell? It is a large cylindrical tube, mainly made of steel, to ensure that the submarine in the underwater activities, can withstand hydrostatic pressure corresponding to the depth? The outer shell is a non-pressure-resistant hull made of steel, not subject to seawater pressure?

The inner hull is separated by a partition into a command compartment? Missile compartment? torpedo compartment? The submarine was divided into a number of compartments, including the command compartment, the missile compartment, the torpedo compartment, and the soldiers' compartment.

The volume between the inner shell of the submarine is mainly ballast water tanks and fuel tanks? The reason why the submarine can dive and float well, mainly by the main ballast water tanks play a role?

Single-hulled submarines have only pressure-resistant hulls, and the main ballast water tanks are arranged in the pressure-resistant hulls. Half-hull submarines, in the pressure-resistant hull on both sides of a part of the shell is not pressure-resistant as the submarine's main ballast water tanks?

The pressure-resistant hull is usually divided into bow? amidships? Stern three sections, separated into three to eight sealed compartments, the compartments are set up with maneuvering and command positions and weapons? equipment? equipment? Various systems and crew living facilities to ensure the normal work of the crew? The first time I saw the ship, I was able to get a good look at it, and it was a good look at the ship.

Modern submarines are installed in the bow section with a large spherical sonar base array and torpedo room, in the torpedo room is generally installed with four to eight torpedo tubes?

Amidships, there are pressure-resistant command room and non-pressure-resistant water command bridge. In the command room and its enclosure, the arrangement of periscope can work in the depth of the periscope? Ventilation pipe and radio communication? Radar? Radar detection and alarm receiver? Radio directional instrument antennae lifting device?

The transom section is mainly installed with power plant and transmission? In the hull on both sides of the general installation of sonar base array? The submarine's bow and stern are equipped with elevating rudders, they and the fins of the fish, as long as you change the rudder and the angle of the water surface, you can make the submarine sailing in the water to change the depth of the submarine, upward or downward sailing, the operation is very convenient?

Additionally, the stern is equipped with a propeller and rudder, which enables the submarine to make left and right turns or maintain the direction of travel. Most submarines are powered by diesel engines and batteries. Modern submarine's primary mission is to attack large and medium-sized surface ships, can also be used to fulfill the reconnaissance? The submarine can also be used to fulfill the tasks of reconnaissance, mine laying and patrolling.

China's Yuan class submarine adopts a teardrop hull with a rounded bow and plenty of bow space. After the upper bow is used to set up six torpedo tubes, there is still plenty of room for sonar arrays to be placed in the lower bow. Therefore, the Yuan class submarine has a new type of integrated sonar at the bow, which improves its search and tracking range.
