The strength of a country, in addition to its own strength, is also closely related to its own technology, military and so on. China is the only country that can independently develop and build aircraft carriers.
Creation of aircraft carriers.
As a large aircraft carrier, the aircraft carrier will encounter more risks when participating in the war, so when it is built, it is necessary to carry out a series of modifications to the aircraft carrier to increase the defense of the aircraft carrier.
You know, this aircraft carrier is made of steel.
1. Steel needed for aircraft carriers.
The aircraft carrier is a sign of the strength of the first team, and it is also a sign of its technological development.
Therefore, when building an aircraft carrier, the choice of materials is also very important. It does not mean that how thick the armor of an aircraft carrier is, it must have a high defensive power.
Everything has a degree, and as the thickness of the steel becomes thicker and thicker, the gravitational pull on the aircraft carrier also increases, which naturally has a certain impact on the buoyancy of the aircraft carrier.
This is undoubtedly an additional overhead for those countries that want to build aircraft carriers, because the mass of aircraft carriers will decrease with their size, and at the same time, it will also have a certain negative impact on their maneuverability.
Therefore, in the process of manufacturing aircraft carriers, it is necessary to take into account the thickness of the steel plates of the hull.
It's like in the cold of winter, everyone will wrap themselves, but not everyone will wrap themselves, and no one will add another padded coat to the outside, because it's a balance.
In fact, if there is enough steel to support the weight of the aircraft carrier, it will be enough.
2. The thickness of the steel plate of the aircraft carrier.
The steel used on aircraft carriers is not set in stone, because the structure and structure of aircraft carriers are not the same, and the steel required is not the same.
For the thickness of the steel plate, it depends on the specific situation.
Types of steel plates used in aircraft carriers.
Aircraft carriers are large ships that can be seen from afar once they are put into the water, and in order to ensure their safety, architects choose various types of steel in the manufacturing process.
1. Steel plate for the hull.
Just as the hull of an aircraft carrier can be divided into two halves, one is exposed to the sea and the other is sinking.
The section that is exposed to the sea, the reason why the steel plate is chosen is because it can withstand the erosion of seawater, and it can also withstand the pressure of seawater. Therefore, there are no high requirements for the thickness of the hull, and generally 23 mm to 28 mm submarine pads are capable of working in an environment of 450-550 MPa.
Underwater armor also has high requirements for the thickness of the steel plates, both against torpedoes and underwater corrosion. Therefore, most of the steel plates with a thickness of 150-203 mm are used. Some aircraft carriers will even build three decks to enhance their ability to withstand pressure.
This is to enhance the buoyancy of the aircraft carrier, but also to provide more protection for the aircraft carrier, even if the outermost steel is penetrated, there will be internal steel to resist.
2. Steel plates for armor.
The armor layer is like the heart of an aircraft carrier, and the control platform is built here. Every member of the aircraft carrier will act according to the instructions on the console. Therefore, on the battlefield, if someone on the command platform of the aircraft carrier is damaged, it is basically the collapse of the entire aircraft carrier.
Since this podium is the center of the entire base, it also requires the thickest amount of steel, comparable to a tank.
An aircraft carrier needs the longest and thickest steel, that is, the metal of the control platform, and inside the aircraft carrier, there are arsenals, nuclear power plants, cockpits, etc. If something goes wrong with this place, then the result is serious.
To put it bluntly, there are only two results, either ** or nuclear ** leakage, and this time, the aircraft carrier will completely lose its course.
3. Steel plates for other parts.
The aircraft carrier, like the airport, is used as a compartment, and the requirements for steel plates are not very high.
For example, the steel required for the airport only requires it to have a certain strength and toughness, and the steel used is usually 40-50 mm, and the construction process should be slightly coarser to increase friction and resistance. As for partitions, as long as they can be effectively isolated.
Take the Ford as an example, it has been serving the U.S. ** team since 2013, and its cost is as high as $13 billion. At the time of construction, the hull was made of a low-alloy steel called HSLA-100, which varies in thickness from 22-28 mm, and the steel of the second flight deck was 40-50 mm, but its yield limit was as high as 800 GPA, which was designated HSLA-115.
The Ford is much smaller than the Nimitz, much cheaper to build, and much more resistant to pressure. The reason for this situation has a lot to do with the use of HSLA series steels, which can be welded directly or in a shorter time.
It has to be said that the creation of an aircraft carrier is not a simple project, but a very brain-intensive one. Without enough financial resources and technology, aircraft carriers simply cannot be built.
