Chapter 81 Xuanwu Alloy, a great underwater world!

After pondering for a moment, Qin Shan spoke again: "Xiao Su, why is there no enclosure on the back of your submarine?"

The enclosure is the island-like thing above the submarine's head.

At present, almost all submarines in the world have such enclosures.

However, Qinshan did not find this thing on the Qianjiao. The entire body of the Qianjiao was like a huge elongated drop of water. The surrounding area was extremely smooth and there was no protruding equipment at all. In Qinshan's view, this was not the case. , somewhat incredible.

You know, the protrusions on the world's mainstream submarines are not deliberately installed after eating too much.

These things all have their own key roles.

Take the enclosure for example. Although the existence of the enclosure makes the submarine look ugly.

However, there are various observation equipment on the submarine, such as periscopes, attack periscopes, search radars, radio direction finders, and various communication equipment, such as transmitting and receiving antennas, satellite communication antennas, and various ESM antennas used for electronic warfare, etc. , these things are almost all in the enclosure!

There are also things like the casing and rudder, which are also on the casing!

In layman's terms, a rudder is what maintains the balance of a submarine. Without this thing, the submarine cannot maintain stability when sailing underwater, and accidents such as rollover may even occur!
  The Third Reich had built submarines without enclosures.

Then the submarine lost its balance and rolled directly into the deep sea...

To this day, hundreds of years have passed, and the submarine's enclosure is still retained. It's not that we don't want to cancel it, but that we simply can't cancel it!

Facing Qin Shan's inquiry, Su Heng slowly said: "The submersible dragon is equipped with multiple stabilizers to maintain stability and direction, and it also has an intelligent monitoring system that can monitor the submarine's navigation attitude in real time and perform intelligent control at the same time. The hull is needed to maintain the balance of the ship."

Hearing this, Qin Shan's eyes moved slightly, and his heart became more and more amazed.

After thinking about it, Qin Shan stepped on the hidden dragon under his feet and said again:

"Xiao Su, what kind of material is your submarine made of? Why does it feel like the outer shell is soft and doesn't look like a metal material?"

Just when he touched the latent dragon, Qin Shan felt something strange about the latent dragon. The touch was not like steel at all. Steel felt hard and had no tactility at all.

But the shell of the latent dragon seemed to be covered with a layer of cowhide. It was soft and beyond Qin Shan's knowledge.

He even wondered for a while whether Su Heng had covered the shell of the hidden dragon with a special layer of anechoic tile-like material...

Amidst Qin Shan's doubts, Su Heng said slowly:

"It is a metal material, but it is a special alloy. I call it Xuanwu alloy. Most of the entire submarine body is made of Xuanwu alloy. This alloy feels similar to cowhide, but in fact Its rigidity and toughness far exceed that of titanium alloy, and it has the characteristics of getting stronger when strong!"

"Well... the professional explanation is too complicated. Simply put, it's like a non-Newtonian fluid. The stronger the pressure, the stronger the rigidity of the basalt alloy!"

"But just like non-Newtonian fluids can also be broken, basalt alloys also have endurance limits. Currently, the maximum depth that the submersible dragon can withstand is recorded by the data I showed you before, which is 1455.8 meters. Beyond this depth, the submersible dragon can dive at any time. They may be crushed by water pressure.”

Listening to Su Heng's response, Qin Shan's eyes kept flickering.

Wisps of wonder kept passing by.

He is not a scientist, and he does not understand professional things.

But what Su Heng explained was easy to understand, and even an ordinary person could understand it.

"I really don't know how your brain is able to create so many incredible things..."

While thinking, Qin Shan couldn't help but sigh.

Hearing this, Su Heng shook his head slightly: "Mr. Qin, you are exaggerating, and if you insist on saying it, I don't call it creation, I can only call it discovery."

"The essence of science is to constantly discover, discover the characteristics of various substances in the universe, and the laws between them, and use these characteristics and laws to create things that meet our needs. In fact, as long as these are discovered, many things It’s easy to figure it out.”

Simple?
  Hearing what Su Heng said, Qin Shan couldn't help but smile bitterly.

The essence of science is discovery. This is indeed true. The whole world cannot deny this.

Just like friction generates heat, primitive people discovered that friction generates heat, thus allowing mankind to enter the "civilized" era.

So is frictional heat created by humans?
  Obviously not. Before there were humans, the universe itself had this law!
  Human beings have just discovered this law and exploited it.

I just say that, but how can it be so easy to find out?

It took primitive people countless thousands of years to discover that friction generates heat!
  Although modern society is highly technologically advanced, it is only achieved by the hard work of countless scientists and countless sweat!
  If it were that easy to discover, it wouldn’t have taken so long for humans to enter modern civilization...

After a long time, Qin Shan shook his head and suppressed the thoughts in his heart.

Then he followed Su Heng's footsteps and walked towards the entrance of the hidden dragon.

It didn't take long for the two of them to arrive at the entrance, but at this moment, as if he thought of something, Qin Shan spoke again:

"Xiao Su, how many decibels is the underwater noise of this submarine?"

Underwater noise is a basic parameter for evaluating the quality of a submarine, especially military submarines.

Military submarines all pursue the smallest possible underwater noise, so that they can minimize the probability of being discovered, and correspondingly, they can maximize their survivability! And what is the most important thing about a strategic submarine?
  It’s not about how many missiles you carry, it’s about survival!

If it doesn't even have survivability, no matter how many missiles it carries, it's just a large living target!
  With the slow stealth speed of a submarine, once discovered, it is basically impossible to escape death!
  Even the most advanced nuclear submarines of Black and White Eagle are the same. Submarines basically have no ability to fight back when faced with anti-submarine weapons!
  In this regard, Dragon Kingdom's submarines are called underwater tractors by black and white eagles because they are too noisy!
  "Is there underwater noise?" Facing Qin Shan's inquiry, Su Heng pondered for a moment, then shook his head slightly: "This has not been tested. The design of Qianjiao is just a sightseeing submarine, and there is no technical requirement in this area."

Hearing this, Qin Shan sighed slightly.

I'm a little disappointed. If the noise of the hidden dragon is too loud, everything else will have to be reconsidered.

As the saying goes, a submarine that cannot be hidden is a living target!

If discovered, the submarine has a slim chance of escaping!

But then I thought about it, with Qianjiao's other parameters that are incredible, even if the noise is too loud, it can still be modified.

With a displacement of 18,000 tons, there is too much redundant space for modification!

Even if 8,000 tons are used as a sound-absorbing transformation space, Qianjiao still has a huge displacement advantage of 10,000 tons!

Still one of the largest submarines in the world!

While Qin Shan was thinking, the two followed the entrance of the Qian Jiao and entered the inside of the Qian Jiao.

"hiss!!"

As soon as he entered the hidden dragon, Qin Shan couldn't help but let out a gasp.

Looking at the bright and spacious space in front of him, Qin Shan couldn't help but open his eyes wide.

"Why is the interior space of your submarine so big?"

At this moment, Qin Shan was shocked again.

As a submariner, what kind of submarine has he not seen?

He has seen almost everything from conventionally powered submarines to strategic nuclear submarines, and he knows the scene inside the submarine very well.

But the scene in front of him was completely beyond his understanding.

The submarines he had seen in the past, whether they were conventionally powered submarines or nuclear-powered submarines, had extremely cramped interior spaces.

Especially for conventionally powered submarines, it is impossible for people to stand and walk inside.

When resting, they were squeezed into a bed that could only accommodate one person's body. It was difficult to turn over!
  Whether at home or abroad, many submariners even suffer from mental illness because of such an environment!
  Because of this situation, almost all submariners around the world have to undergo a physical and mental health examination every once in a while. Once a problem occurs, they have to go to the hospital for medical treatment as soon as possible. In serious cases, they may even be retired directly!
  As for the hidden dragon in front of us, the internal space can only be described as an exaggeration!
  The spacious and bright space once made Qin Shan think that he was not visiting a submarine, but a luxurious villa!

"Is it big?" Hearing Qin Shan's exclamation, Su Heng looked around and then shook his head slightly.

Is this big?
  The maximum displacement of the submersible dragon he originally designed reached 30,000 tons!
  However, considering cost issues and port commuting conditions, in order to avoid the embarrassing situation like the empty 380 passenger plane, Su Heng modified the submersible dragon and reduced the displacement to tons.

Compared with the original design, these 18,000-ton latent dragons can only be regarded as babies. How big are they...

Noticing Su Heng's nonchalant and even slightly disgusted look, Qin Shan's lips twitched slightly.

With his IQ, he could easily judge Su Heng's thoughts.

"Xiao Su, I will take you to see our nuclear submarine another day."

With a slight sigh, Qin Shan spoke quietly.

Hearing this, Su Heng was startled.

Then his eyes lit up.

To be honest, he was not very interested in nuclear submarines.

He really doesn't know much about military affairs, but he also knows the basics of modern ships. Whether it is military or civilian, it is nothing more than boiling water!
  The so-called nuclear power is just a different kind of fuel used to boil water.

It sounds high-end, but in fact it's just that.

The most fundamental reason why Su Heng dislikes nuclear power, apart from the pollution caused by nuclear power, is this.

To Su Heng, things that boil water really have no appeal.

However, although Su Heng was not interested in boiling water, he was very interested in the weapons on nuclear-powered submarines.

He has been tinkering with the latent dragon for a while, but isn't he tinkering with weapons?

Originally, he wanted to add electromagnetic weapons to it, but electromagnetic weapons obviously didn't work underwater, so this plan was abandoned after Su Heng studied it.

The same goes for high-energy weapons. The underwater environment is not suitable for the use of high-energy weapons at all.

He was thinking about whether to add a ramming angle to the submarine and directly drive the submarine to ram it. Now Qinshan offered to let him visit the nuclear submarine. This was just giving him a pillow when he fell asleep.
