Dreaming back to 90, starting to develop B2 bombers!

Everyone is impressed! The project’s destiny is bright! Bomber, B2!

“This is Gou Yi, the dean of our Materials Branch.”

Seeing Gou Yi stand up, Hu Weinan quickly introduced him to Yu Bei.

“Hello, Dean Gou.”

Yu Bei looked at Gou Yi in front of him with some surprise. He was also a little surprised that even the dean of the branch stood up directly.

“Haha, student Yu Bei, let me make it clear first that I am not targeting you. When we had the earliest disagreements, I was on your side. You can ask Dean Wang Zheng about this. I just can’t bear it. ”

Gou Yi said with a smile.

“Yes, I can prove this.”

Wang Zheng nodded.

“This is the dean of the Aerodynamics Branch, Wang Zheng.”

Hu Weinan introduced again.

“Ahem, Lao Gou, don’t add jealousy there. We have never had any hostility towards Bei. We just want to know if Yu Bei can lead us to complete this project.”

“Yes, Lao Gou, what you say is too disrespectful to us. Do you want to divide us by co-authoring it?”

“That’s right, Lao Gou, don’t talk nonsense here.”

The deans of several other branches also smiled helplessly at this time, and then quickly explained.

Hu Weinan also introduced them to Yu Bei one by one.

Faced with everyone’s explanations, Yu Bei certainly believed it. After all, he was able to come up with such a design at such a young age. If it were him, he would have doubts!

“Dean Gou, what do you want to say?”

Yu Bei smiled, then looked at Gou Yi and said.

Gou Yi’s face straightened: “I looked at the bomber design drawing and it said that the stealth of our bomber is mainly achieved by using invisible materials to absorb radar waves. I want to know what kind of material can do this.”

Hearing Gou Yi’s words, Yu Bei suddenly understood, nodded and explained,

“The radar absorbing coating I designed is mainly composed of base material and filler, which is essentially a functional polymer composite coating.

Among them, the base material mainly plays a bonding role.

Filling is the main component that absorbs radar waves.Points, after my research, the specially prepared ferromagnetic materials such as MgO, FeO, ZnO, etc. have prismatic crystals that can continuously absorb incident waves! ! ”

“Furthermore, these materials also have a certain degree of porosity, which can fully absorb the inner layer and cause wave scattering due to the interference between the incident wave and the reflected wave. As long as we apply radar absorbing coating on the surface of the bomber, it can effectively Reduce the target’s radar cross section.”

Yu Bei answered fluently again.

“Ferromagnetic materials such as MgO, FeO, ZnO… can these things really absorb the electromagnetic waves of radar!?”

After Gou Yi heard this, he was stunned for a moment. He originally thought that Yu Bei would talk about some materials that he didn’t know. However, it was indeed unknown to him that these very common materials could actually have such an effect!

“Of course, and using these materials, the radar’s reflected wave can be attenuated to 5% to 10% of the incident wave.”

Yu Bei nodded.

“What!? Can the reflected wave attenuate to five to ten percent of the incident wave!?”

“I’ll go, this is too exaggerated!! Is it really so amazing!?”

“If the attenuation power is like this, wouldn’t it mean that a bomber would look about the same size as a sparrow when viewed on radar!?”

As soon as Yu Bei finished speaking, a group of academicians were shocked!

Everyone knows that the working principle of radar is to detect by emitting electromagnetic waves and collecting reflected waves!

Now what Yu Bei said is that these commonly used ferromagnetic materials can actually attenuate reflected waves to this extent, which is a bit too exaggerated!

“Haha, these are all the data that I have tested, and some data from my experiments. Because I was in a hurry when I sent the design drawing last time, I did not attach these data to the design drawing.”

Yu Bei smiled, and then took out a thick piece of information from his backpack.

Of course, these information are also provided by the system.

“Let me take a look!”

When Gou heard this, his eyes lit up and he immediately took the information!

Then, they started to look at it on the spot, and as time passed, Gou Yi’s eyes became particularly shocked! !

These experimental data are clearly written!

Moreover, the experimental process is also very detailed!

“It’s true! It’s actually true. It turns out that these things combined have such a strong ability to absorb electromagnetic waves!”

When Gou Yi saw the end, he couldn’t help but take a deep breath and murmured.

Then, he looked up at Yu Bei again,

“Student Yu Bei, can you give me this information? I want the academicians in our academy to go through this experimental process again!”

“No problem, Dean Gou, but what I want to say is that this material is not the best. In my judgment, if some unique lanthanide elements in rare earths are added to these materials, the reflected waves may even be attenuated. To zero, let the bomber completely disappear from the radar!”

“It’s just that my conditions were limited at the time and I couldn’t get these things, so it was only theoretically feasible.”

Yu Bei smiled and then said.

“Attenuate to zero!?”

When Gou heard Yu Bei’s words, his heart almost jumped out of his chest!

For scientific researchers, one hundred percent and zero are definitely the hardest things to say!

Due to scientific rigor, in ordinary experiments or projects, even if there is a possibility of one in ten thousand or even one in a billion, there is no way to say these two words!

But I didn’t expect that Yu Bei, at such a young age, would be so confident in saying the word zero!

“Rare earths? This is indeed difficult to obtain. Now our Daxia Kingdom has also listed rare earths as important land resources. But if you need it, I can apply to the above, and it should be approved.”

Hu Weinan was also shocked, and then quickly said to Yu Bei.

“There’s no rush, Dean Hu. We’d better finish the entire bomber frame first. Applying the invisible material will naturally be done last.”

Yu Bei smiled and said.

Then, he looked at the other academicians.

“Dear academicians, do you have any other questions?”

When a group of academicians heard what Yu Bei said, they immediately looked at me and saw that you didn’t dare to come out again!

“Haha, it turns out that a boy is born a hero…”

And at this moment, Wang Zheng walked out.

But he didn’t come here to ask questions. His previous questions had already been answered by Gou Yi.

I saw him looking at Yu Bei, his eyes full of satisfaction, then he took off his hat and said in a deep voice to Yu Bei,

“Yu Gong, please be invisible for usLet’s name the bomber project! ”

The other academicians also reacted when they heard Wang Zheng’s words, and then they all nodded and said,

“Yu Gong, please give me a name!”

Everyone was completely impressed by Yu Bei’s talent and learning at this moment!

Yu Bei looked at the group of academicians in front of him and exhaled. Thinking of the turbulent world situation in this era, his eyes flickered and he said,

“The project codename will be Liangjian, and this series of stealth bombers will be named B2!”
