Dream back to 90, start the development of B2 bomber!

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

Seeing Gou Yi standing up, Hu Weinan hurriedly introduced Yu Bei.

“Hello, Dean Gou.”

Yu Bei looked at Gou Yi in front of him with some surprise, and he was also a little surprised in his heart, and even the head of the branch directly stood up.

“Hehe, Yu Bei, I will first declare, I am not against you, in the earliest disagreement, 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 head of the aerodynamics branch, Wang Zheng.”

Hu Weinan introduced again.

“Ahem, Lao Gou, don’t add oil and vinegar 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, it’s too shameful for you to say this, and you want to divide us?”

“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.

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

In the face of everyone’s explanation, Yu Bei certainly believed it, after all, he was able to make such a design drawing at such a young age, if he changed to him, he would also doubt it!

“Dean Gou, what do you want to say?”

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

Gou Yi’s face turned serious: “I looked at the bomber design drawing and said that our bomber stealth is mainly done by absorbing the waves of the radar with stealth materials.” I wonder what material exactly does this. ”

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

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

Among them, the binder mainly plays a bonding role.

Fillers are the main components that absorb radar waves, and the ferromagnetic composition materials specially made by MgO, FeO, ZnO, etc. after my research have prismatic crystals that can continuously absorb incident waves!! ”

“Moreover, these materials also have a certain porosity, which can fully absorb the inner layer and cause wave scattering due to interference between incident waves and reflected waves, as long as we apply radar absorbing paint on the surface of the bomber, we can effectively reduce the radar scattering section of the target.”

Yu Bei answered like a fluent.

“Ferromagnetic composition materials of MgO, FeO, ZnO, etc… Can these things really absorb the electromagnetic waves of the radar !? ”

After hearing this, he was stunned for a moment, originally he thought that Yu Bei would say some materials that he didn’t know, but these very common materials could actually play such a role, which he really didn’t know!

“Of course, and with these materials, the reflected waves of the radar can be attenuated to 5 to 10 percent of the incident waves.”

Yu Bei nodded.

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

“I’ll go, that’s an exaggeration!! Is there such a god!? ”

“If you follow this attenuation power, wouldn’t a bomber look about the size of a sparrow on radar!?”

As soon as Yu Bei’s voice fell, a group of academicians were shocked!

Everyone knows that the working principle of radar is to form a detection by transmitting electromagnetic waves to collect reflected waves!

And now these commonly used ferromagnetic materials mentioned by Yu Bei can actually attenuate the reflected wave to such an extent, which is inevitably too exaggerated!

“Hehe, these are all data that I have tested this is, I do experiments. Because the last time I sent the design drawings, I was in a hurry, so I did not attach this data to the design drawings. ”

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

Of course, these materials are also given by the system.

“I’ll take a look!”

As soon as Gou heard this, his eyes lit up, and he immediately took the information!

Then, he looked at it on the spot, and as time passed, Gou Yi’s eyes became extremely shocked!!

These experimental data are clearly written!

Moreover, the process of the experiment is also detailed!

“It really is! It’s actually true, it turns out that these things are combined to 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 muttered in his mouth.

Then, he looked up at Yu Bei

“Student Yu Bei, can you give me this information, I want our academicians 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 lanthanides in rare earths are added to these materials, it may even attenuate the reflected wave to zero, making the bomber completely disappear on the radar!”

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

Yu Bei smiled, and then said.

“Attenuation to zero!?”

As soon as Gou heard Yu Bei’s words, his heart was about to jump out!

For researchers, 100% and zero are definitely the most difficult 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!

And I didn’t expect Yu Bei to be so confident to say the word zero so young!

“Rare earths? This is indeed more difficult to get, and now our Great Xia Kingdom also lists rare earths as important national land resources. But if you need it, I can apply to the above, and it should be able to be approved. ”

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

“No hurry, Dean Hu, we still need to complete the entire bomber frame first, and the matter of smearing invisible materials is naturally done last.”

Yu Bei said with a smile.

Then, he looked at the other academicians.

“Academicians, do you have any other questions?”

A group of academicians heard Yu Bei’s words, and suddenly you look at me and I see that you dare not come out again!

“Hehe, it’s really a hero out of a teenager…”

And at this time, Wang Zheng walked out.

But he didn’t come to ask questions, his previous questions had already been voiced.

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

“Yu Gong, please name our stealth bomber project!”

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

“Yu Gong, please take a name!”

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

Yu Bei looked at a group of academicians in front of him, and also exhaled, thinking of the strangeness of the world pattern in this era, and the light in his eyes flickered, and said,

“The project code name is Bright Sword, and as for this stealth bomber, it is named B2!”
