Chapter 925 Technical Shock
The stealth fighter is not really invisible. Its invisibility 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 scan the existence of the fighter, then the stealth fighter can be in It has achieved unimaginable results on the battlefield.
However, stealth fighters are not perfect. First of all, the cost of stealth fighters is very high, and the maintenance cost is also very staggering. Some weaker countries simply cannot afford stealth fighters.
Secondly, in order to achieve the stealth effect, the stealth fighter has to sacrifice power and even some performance in addition to the special shape of the fuselage.
This is almost common sense in the scientific research community, but this common sense is that no country has been able to make a breakthrough for the time being.
Even the United States, the overlord of the stealth fighter world, is the same.
However, in front of Du Cheng, who has the knowledge of future science and technology, there is no difficulty or problem in all of this.
Under Du Cheng's signal, one of the scientific research members came over pushing a cart, and there were more than 20 telescopes in it.
When these telescopes were distributed to the eyes of the Prime Minister and everyone in Ye Nanling, Du Cheng said: "This Stealth stealth fighter uses the wide-band wave-absorbing material developed by our scientific research base. It is made by adding energy plastic material to the matrix of polyurethane chemically modified multilayer foam, which maintains effectiveness in a fairly wide frequency range. The radar absorbing material is combined with a rigid material that can pass through radar energy Combined, its reflected energy is almost zero, even compared to the reflected energy of a mosquito, it is about ten times smaller."
Du Cheng gave a brief introduction to this technology, and after a pause, he went on to say: "This material has very little regulation on the structure of the fuselage and flow shaping, so the stalker we studied Stealth fighters are currently at the top level in the world in terms of power performance and attack..."
After there is no streamlined shape, the design of the fighter will not have the restrictions on the shape, and there is no need to sacrifice power and performance. .
"..."
After Du Cheng finished speaking, the Prime Minister and Ye Nanling were already stunned again.
Originally they thought that the effect of this stealth fighter was extremely amazing, but they did not expect that the stealth fighter Du Cheng showed was so superior that it was almost terrifying.
Moreover, they heard another more important news from Du Cheng's tone. No wonder they looked very familiar when they looked at the stealth fighter just now, because the stealth fighter seemed to have been slightly improved by Du Cheng. new Boeing fighter jet.
Ye Nanling glanced at Du Cheng, and then asked directly: "Du Cheng, you mean that the new wave-absorbing material you have researched can be used on any aircraft?"
At this time, he finally understood why Du Cheng kept it a secret yesterday, because only after keeping it a secret would the research results of this time be more astonishing.
Du Cheng nodded lightly, and said: "Almost, as long as the body size is not larger than a large airliner, basically most of the aircraft can achieve the purpose of invisibility as long as they are coated with this material."
His words, while explaining to Ye Nanling, also explained one point, that is, the most successful research this time is this new type of wave-absorbing material. As for the fighter, what Du Cheng said is nice, In fact, it was just a high-level fighter plane transferred from the military and coated with that layer of wave-absorbing material.
However, the research on the wave-absorbing material consumed a great deal of painstaking effort and efforts of Du Cheng and a group of scientific researchers.
As for the answer from the listener Du Cheng, the Prime Minister and Ye Nanling looked at each other in blank dismay. Obviously, they both saw what this technology really represented, which was far more astonishing than what they had 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 wave-absorbing material?"
The wave-absorbing material developed by Du Cheng is easy to use, but the cost required is too staggering, and if the production capacity is low, then its usefulness will be greatly limited.
It can be said that this is the matter that the Prime Minister is most concerned about at the moment.
Du Cheng had already considered this point. Hearing what the Prime Minister said, he said very simply: "Prime Minister, the manufacturing cost of this wave-absorbing material is very low. If it is just an ordinary stealth fighter, the cost will not More than 1.6 million, if large-scale research and production are carried out, I think it should be possible to produce roughly three absorbing materials for stealth fighters per day."
It seems that the production capacity of three planes a day seems a little low, but if it takes ten days, twenty days, or one year or two years, it only takes a certain amount of time to accumulate, and it is completely possible to form a team of the most terrifying stealth fighters in the world. The fighter team came out.
Moreover, the cost of this kind of wave-absorbing material is not too astonishing. Even if it is painted on a thousand frames, it will be more than ten billion at most. Even if it is several times more, based on China's current international performance In terms of financial resources, it can be fully supported.
After listening to Du Cheng finished speaking, the Prime Minister was obviously relieved, but the excited expression on his face became stronger.
Not only him, but even Ye Nanling and Ye Chengtu saw the future scene at this moment, as if countless stalkers in the sky were waving at them. . .
Du Cheng did not bother them, but after winking at Team Leader Guan, he said slowly: "Prime Minister, this is the first technology we have researched, come with me, I will show you Let's take a look at the second technology demonstrated this time."
"Is there a second technology?"
Just because of the first technology, the Prime Minister and the others were already extremely excited. He never thought that Du Cheng was actually ready for the second technology.
Therefore, when Du Cheng talked about the second technology, whether it was the Prime Minister or Ye Nanling, everyone's faces were full of anticipation.
After experiencing the impact of the first technology, each of them is full of expectations for the second technology that Du Cheng will develop next.
Du Cheng nodded lightly, and then said: "Prime Minister, please come with me, I will take you to another exhibition hall."
After finishing speaking, Du Cheng didn't stop there, but directly led the Prime Minister and Ye Nanling together towards the gate where he and the scientific researchers walked out.
Those scientific researchers also followed Du Cheng and the others one by one, and some excited expressions could be seen on their faces. It also seems to be looking forward to the demonstration of the second technology.
---------------------------------------
Compared with the previous hall, the front of the second hall is obviously much smaller.
The hall is also very empty, only a workbench is placed in the middle of the hall, and several large pieces of metal are placed on the workbench.
Apart from that, nothing else can be seen outside the entire hall.
This made the Prime Minister and the others a little bit puzzled, because those large pieces of metal seemed to be either iron or steel, and there were some alloys, which seemed to have nothing outstanding.
"Ye Hu, come here."
Du Cheng didn't explain anything right away, but waved towards Ye Hu. After waiting for Ye Hu to approach, Du Cheng took out an electromagnetic laser knife that he had prepared a long time ago from the side of the workbench, and handed it to Ye Hu. After Ye Hu, he said: "Ye Hu, try to stab a few times on these metals, and you can do it casually."
Although Ye Hu didn't understand what Du Cheng's second new technology was, he didn't have the slightest doubt about what Du Cheng said. Without even thinking about it, he directly turned on the electromagnetic laser knife. After waiting for the electromagnetic laser knife to flash out, he held the knife tightly and stabbed straight towards the large pieces of metal.
And in the back, the Prime Minister and the others' eyes were already focused on those metal stones, as if they could see the flowers from those metals.
Ye Hu's movements were very fast. In just a few seconds, he stabbed more than a dozen stabs easily. With the terrifying edge of the electromagnetic laser knife, he stabbed a small hole directly with almost every stab.
If it were replaced by a human body, I am afraid that there would have been more than a dozen holes.
After stabbing, Ye Hu directly turned off the switch of the electromagnetic laser knife, and just as he was about to hand the knife back to Du Cheng, a strange scene happened before his eyes.
I saw that the metal at the pierced hole seemed to become liquid, and then, the metal began to move rapidly, and the small hole was rapidly shrinking, only less than ten In seconds, those pierced holes were all healed, as if they hadn't been pierced at all.
"this...."
Just looking at this weird scene, Ye Hu was completely stunned, his mouth was opened wide, and he almost shouted out 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 the metal.
It's just that everything remains the same, and in less than ten seconds, those small holes have all healed by themselves. . .
Behind him, the Prime Minister and the others had similar expressions.
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 life-living bodies.
Ye Hu finally came to his senses, 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?"
"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 murmured softly, he can be sure that the name used on these metals seems to be more appropriate.
Only metal with life can heal itself when it is injured, but all of this seems a little too weird.
"Du Cheng, how did you do it...?"
Ye Hu asked very directly. Not only did he not think of this matter, the Prime Minister and the others also couldn't think of it.
Although a metal self-repair technology has appeared in the world at present, it is an ultrafine powder composite material composed of various mineral components such as hydroxymagnesium silicate, additives and catalysts, that is, a self-repair material for metal wear.
However, the principle of this self-healing material for metal wear is completely different. It is used by adding to various types of lubricating oil or grease. Using lubricating oil or grease as a carrier, the fine powder of the repairing material is sent to the working surface of the friction object to achieve the effect of repairing the metal.
Moreover, this kind of repair only needs to be repaired with a small arc of wear and tear. Compared with this kind of repair at this moment, it is definitely the difference between a firefly and a scorching sun.
Du Cheng did not answer right away, but asked a researcher to take out a laptop computer and put it in front of everyone. After the relevant screen was played on the computer and directly projected and enlarged, he said: "We are Some researches have been carried out on metal wear self-repairing materials, and a very unique chemical catalytic component has been extracted. After this chemical catalytic component is combined with mechanochemical action, it can be excited by the heat energy generated by metal friction, and these metals, It is refined by fusing this chemical catalyst."
After a pause, Du Cheng pointed directly at the screen in the computer and continued: "Ye Hu, it's like you stabbed in with an electromagnetic laser knife just now, the heat energy generated by the electromagnetic laser knife quickly excited Chemical catalytic components, the chemical catalytic components contained in these metals are activated under the mechanochemical action of thermal energy, so as to achieve the ability of self-cultivation.”
What Du Cheng said was very simple and a little profound, but after matching the pictures played by the computer, everything became very clear.
Not only that, in the video that Du Cheng had already recorded, he even gave a detailed description of the chemical catalytic ingredients, and also gave a straightforward explanation of the principle behind the two excitations.
Under such circumstances, even Ye Hu, who has no knowledge of this aspect at all, has a general understanding of this second technology.

The third one is delivered and will continue tomorrow.
