The stealth fighter is not really invisible, its stealth is not invisible to our naked eyes, the real purpose is to make the radar unable to detect the existence of the aircraft, as long as the radar cannot detect the existence of the fighter, then, the stealth fighter can play an unimaginable role on the battlefield.

First of all, the cost of stealth fighters is very high, and the maintenance costs are also very amazing.

Secondly, in order to achieve the effect of stealth, coupled with the special shape of the fuselage, the stealth fighter has to sacrifice power and even some surnames.

This is almost common sense in the scientific research community, but this common sense is that no country can make a breakthrough for the time being.

Even the United States, the hegemon in the stealth fighter world, is the same.

However, in front of Du Cheng, who has knowledge of future science and technology, there are no difficulties and problems in all this.

At Du Cheng's suggestion, one of the scientific research members came over with a cart, and there were more than 20 telescopes inside.

When these telescopes were assigned to the eyes of the prime minister and Ye Nanling, Du Cheng said: "This stalker stealth fighter is made of wide-band absorbing materials researched by our scientific research base, and is made of carbon energy-dissipating plastic materials added to the matrix of polyurethane chemically deteriorated multi-layer foam, which remains effective in a fairly wide frequency range. Combining radar absorbing materials with rigid substances that radar energy can penetrate, the reflected energy is almost zero, even if it is about ten times smaller than the reflected energy of a mosquito. ”

Du Cheng gave a brief introduction to this technology, and after a pause, he continued: "This material has very little regulations on the structure and flow shaping of the fuselage, so the Stalker stealth fighter we studied is currently the world's top level in terms of power and attack......

After there is no prescribed surname for flow shaping, there is no restriction on the shape of the fighter's design, and there is no need to sacrifice power and surname......

“……”

After listening to Du Cheng's words, the prime minister and Ye Nanling were already stunned again.

Originally, they thought that the effect of this stalker fighter was already extremely amazing, but they didn't expect that the stalker fighter shown by Du Cheng would have an advantage that was almost terrifying.

Moreover, they heard another more important news from Du Cheng's tone, no wonder they were very familiar when they looked at the stealth fighter just now, because the stealth fighter seemed to be a new Boeing fighter that had been slightly improved by Du Cheng.

Ye Nanling glanced at Du Cheng, and then asked directly: "Du Cheng, do you mean that the new absorbing materials you have researched can be used in any aircraft?" ”

At this time, he finally understood why Du Cheng wanted to keep it secret yesterday, because only after keeping it secret would the research results this time be even more amazing.

Du Cheng nodded lightly and said: "Almost, as long as the body size does not exceed that of a large passenger aircraft, basically most aircraft can achieve the purpose of invisibility as long as they are coated with this layer of material." ”

While explaining this sentence to Ye Nanling, he also explained one point, that is, the most successful research this time is this new type of absorbing material, as for that fighter, what Du Cheng said is good, in fact, it is just a high-level fighter plane transferred from the military and coated with that layer of absorbing material.

It's just that the research of absorbing materials has consumed a lot of effort and effort from Du Cheng and a group of scientific researchers.

And the listener Du Cheng's answer, the prime minister and Ye Nanling have already looked at each other, obviously, they have seen what this technology really represents, far more amazing than they imagined.

Immediately, the prime minister seemed to have thought of something, and asked Du Cheng directly: "Du Cheng, what is the manufacturing cost and speed of this absorbing material?" ”

The absorbing material researched by Du Cheng is easy to use, but the cost required is too amazing, and if the production capacity is low, then its usefulness will also be very limited.

It can be said that this is the most important thing that the prime minister is most concerned about at the moment.

Du Cheng has long considered this, listening to what the prime minister said, he said very simply: "Prime minister, the manufacturing cost of this absorbing material is very low, if it is just an ordinary stealth fighter, the cost will not exceed 1.6 million, if large-scale research and production is carried out, I think it should be possible to produce roughly three stealth fighters per day." ”

It seems that the production capacity of three planes a day seems to be a little lower, but if it takes only a certain amount of time to accumulate in ten days, twenty days, or a year or two years, it is completely possible to form the world's most terrifying stealth fighter team.

Moreover, the cost of this absorbing material is not too amazing, even if it is painted with a thousand, it will be more than 10 billion at most, even if it is several times more, in terms of China's current financial resources in the world, it can be raised.

After listening to Du Cheng, the prime minister was obviously relieved, but the excited look on his face was a little stronger.

Not only him, but even Ye Nanling and Ye Chengtu all saw a scene in the future at this moment, as if countless stalkers in the sky were waving to them......

Du Cheng didn't bother them, but after giving Team Leader Guan a look, he said slowly: "Prime Minister, this is the first technology we have researched, come with me, I will take you to see the second technology displayed this time." ”

"And a second technology?"

It's just that with the first technology, the prime minister and they are already very excited, and he didn't expect that Du Cheng would actually prepare the second technology.

Therefore, when they heard Du Cheng talk about the second technology, whether it was the prime minister or Ye Nanling, their faces were already full of expectation.

After experiencing the impact of the first technology, each of them was full of expectations for the second technology that Du Cheng would develop next.

Du Cheng nodded slightly, and then said, "Prime Minister, please come with me, and I'll take you to another exhibition hall." ”

After speaking, Du Cheng didn't stop anything, but directly took the prime minister and Ye Nanling and them together, and walked towards the gate where he and those scientific researchers walked out before.

Those scientific researchers also followed behind Du Cheng one by one, and a little excitement could be faintly seen on their faces. It seems that I am looking forward to the demonstration of the second technology.

Compared to the previous hall, the second hall is significantly smaller in front of it.

The hall was also very empty, except for a workbench in the middle of the hall, on which several large pieces of metal were placed.

Other than that, there was nothing else to be seen outside the entire hall.

This made the prime minister and the others a little puzzled, because those large pieces of metal looked like either iron or steel, and there were some alloys, which didn't seem to be outstanding.

"Ye Hu, come over for a moment."

Du Cheng didn't explain anything immediately, but beckoned to Ye Hu, and after Ye Hu approached, Du Cheng directly took out an electromagnetic laser knife that had been prepared long ago from the side of the workbench, handed it to Ye Hu, and said, "Ye Hu, you try to stab a few knives on these metals, just stab them casually." ”

Although Ye Hu didn't understand what kind of technology Du Cheng's second new technology was displayed, he didn't have the slightest doubt about what Du Cheng said, and he didn't even think about it, he directly turned on the switch of the electromagnetic laser knife, and after the electromagnetic laser knife flashed out, he directly held the knife and stabbed straight towards those large pieces of metal.

Later, the Prime Minister's eyes were already focused on the metal stones, as if they could see the metal flowers.

Ye Hu's movements were very fast, in just a few seconds, he had easily stabbed out more than a dozen knives, with the terrifying edge of the electromagnetic laser knife, almost every knife he directly stabbed out of a small hole.

If you change the body of Chengren, I'm afraid there will be more than a dozen holes long ago.

After stabbing him, Ye Hu directly turned off the switch of the electromagnetic laser knife, and just when he was about to hand the knife back to Du Cheng, a strange scene happened in front of his eyes.

I saw that at the pierced hole, the metal seemed to have turned into fluid, and then, the metal began to move rapidly, and the small hole was rapidly getting smaller, but in less than ten seconds, the pierced hole was all healed, as if it had not been pierced at all.

"This ......"

Just looking at this strange scene, Ye Hu's whole person was completely stunned, his mouth was wide open, and he almost shouted "Hell".

Out of instinct, Ye Hu turned on the switch of the electromagnetic laser knife again, and then pierced more than a dozen small holes in those metals.

It's just that everything is still the same, but in less than ten seconds, those little holes have all healed on their own......

And behind him, the prime minister's face is similar.

Compared with the first technology, this second technology seems to have a greater impact on them.

In their eyes, these metals are no longer cold metal bodies, but have life—living bodies.

Ye Hu finally reacted, and even forgot to turn off the switch of the laser knife in his hand, but asked Du Cheng: "Du Cheng, what's going on, how can these metals heal on their own?" ”

"I forgot to tell you the names of these metals."

Du Cheng smiled slightly, and then explained: "On the surface, these metals seem to be no different from ordinary metals, but they all have a very unique name, that is, life metal. ”

"Life Metal ......"

Ye Hu muttered lightly, he was sure that the name seemed to be more appropriate to use on these metals.

Only the metal with life will heal itself when it is wounded, but it all seems too weird.

"Du Cheng, how did you do it......?"

Ye Hu asked very directly, not only did he not think of this matter, but the prime minister also couldn't think of it.

Although there is a metal self-healing technology in the world, it is an ultra-fine powder composite material composed of various mineral components, additives and catalysts such as magnesium hydroxysilicate, that is, metal wear self-healing materials.

However, the principle of this metal wear self-healing material is completely different, it is used by adding it to various types of lubricants or greases. Using lubricating oil or grease as the carrier, the fine powder particles of the repair material are fed into the working surface of the friction to achieve the effect of repairing the metal.

And this kind of repair, only through a small arc of wear repair, compared with this kind of repair at the moment, it is definitely the difference between fireflies and blazing.

Du Cheng didn't answer immediately, but asked a scientific researcher to take out a laptop computer and put it in front of everyone, waiting for the relevant picture to be played in the computer and directly projected and enlarged, then he said: "We have conducted some research on metal wear self-healing materials, and extracted one of the very unique chemical catalytic components, after this chemical catalytic component is combined with mechanical chemistry, it can be excited by the heat energy generated by metal friction, and these metals, It is made by combining this chemical catalytic ingredient. ”

After a pause, Du Cheng directly pointed to the picture in the computer and continued: "Ye Hu, just like you just stabbed it with an electromagnetic laser knife, the heat energy generated by the electromagnetic laser knife quickly excites the chemical catalytic components in these metals, and the chemical catalytic components contained in these metals themselves are excited under the mechanical and chemical action of thermal energy, so as to achieve the ability of self-cultivation. ”

What Du Cheng said is very simple and a little profound, but after cooperating with the picture flipped by the computer, everything has become very clear.

Not only that, but in the video that Du Cheng had already recorded, he gave a detailed description of the chemical catalytic components, and also made a direct explanation of the principle after the two were excited.

In this case, even Ye Hu, who had no knowledge of this aspect at all, had a general understanding of this second technology.
