What are the characteristics of 2 1 century submarines?

Modern submarines can not only dive underwater, but also sail on the surface. It is mainly used to attack enemy surface ships and submarines and destroy and destroy enemy bases, ports and shore-based targets. Submarines carrying nuclear missiles can also attack enemy targets inland. The nuclear submarine can sail underwater at high speed for a long time and is a promising naval vessel.

With the development of science and technology and the increasing demand for naval warfare, military strategists are drawing blueprints for future submarines, which will have the following characteristics: First, they will move towards high speed. The submarine's sailing speed is fast, which can not only occupy the favorable position in advance to give the opponent a sudden blow, but also quickly avoid the enemy's attack and ensure its own safety. Most submarines will use nuclear engines in the future.

In order to improve the sailing speed, it is necessary to reduce the resistance of submarine sailing underwater. Therefore, it is necessary to avoid opening holes in the hull and improve the smoothness of the hull surface as much as possible. The test shows that wrapping a layer of elastic material on the submarine surface can reduce the resistance by 60%.

Spraying a layer of polymer solution on the submarine hull can also reduce the resistance. It is predicted that if all these measures are adopted, the submarine's underwater sailing speed will reach 50 ~ 60 knots in the future. It is also proposed to build a "skin-moving submarine" so that the submarine can bend forward like a snake to increase the speed of navigation.

The second is to increase the depth of dive. With the increase of diving depth, the submarine can move more widely, which can better fight and hide, and at the same time avoid the attack of enemy anti-submarine forces.

At present, the maximum dive depth of the submarine is 500 meters. Beyond this depth, the submarine hull will be crushed by seawater pressure, and the submarine hull of titanium alloy can dive 1400 meters; The reinforced plastic shell can dive more than 4000 meters. Future submarines are likely to be made of reinforced plastics.

The third is to reduce noise. The submarine's engine and propeller make noise when they work. The noise is low, the submarine can move more stealthily, and the enemy sonar is not easy to find itself. Now France has made a silent submarine.

The fourth is to extend the incubation period. A box-type oxygen-making equipment made of special drugs can provide the submarine with oxygen needed for a one-year incubation period with only one box, and can also absorb the carbon dioxide gas discharged by the human body to keep the air in the cabin clean.

The fifth is to strengthen the contact with the shore by neutrino communication; Holographic photography of the outside of the boat is carried out with ultrasonic waves, so that the personnel in the submarine can clearly see the three-dimensional image of the outside of the boat.

Sixth, the use of advanced weapons. Including the use of advanced weapons such as particle beams.

Seventh, realize automatic control. Using computers and advanced control devices, the operation and command of submarines are fully automated.
