Section 314

Time passed quickly.

Fei City and Jinling are the nearest provincial capitals in China. In addition, they are located in the plains of the Yangtze River Delta, with flat terrain and convenient transportation, so it only takes about two hours to drive there.

Finally, after going around, the car stopped in front of a large courtyard near Zijin Mountain.

This courtyard looks a bit old, but the fact that it can be built here in Zijin Mountain also shows that this courtyard is not simple. As for the white sign at the door and the soldiers standing guard, there is no need to say more.

And Luo Mingya’s research institute is also located here. From the outside, it is really hard to imagine that this was once a confidential research institute.

"Finally arrived."

Identified and entered the courtyard.

After getting off the car, Luo Mingya stretched her body and talked with Xiao Yi about their research progress for a long time. She was a little tired.

Xiao Yi and Wang Li said a few words, and then got off the car.

And Wang Changhong and others also came over.

As for Director Liu, he had other things to do in Jinling, so he separated from them after entering Jinling.

Then, under the leadership of Wang Changhong, Xiao Yi came to the institute.

At this time, he also saw how strict the internal security of a truly confidential institute was. If you want to enter the core area, you must not only swipe your work badge, but also have iris verification.

On the other hand, their Science Island Laboratory only needs to swipe a work badge at most.

Of course, the nature of the two is different after all, so there is no need to compare.

However, Xiao Yi couldn't help thinking with a bad taste in his heart. At least the Science Island Laboratory sounds safer. What if some super agents want to break in? Don't they have to remove the eyeballs of an unlucky researcher first to obtain iris verification?

"Let's take Chief Xiao to record the iris first."

At this time, Wang Changhong said to the person next to him.

The bad taste in Xiao Yi's heart disappeared immediately.

Chapter 261 Two Methods

Xiao Yi warned himself in his heart that it would be better to have less bad taste in the future, otherwise, like now, he would accidentally "bad taste" himself.

For the time being, he waved his hand and said, "Iris is not in a hurry, let me see the specific information of your materials first."

Hearing what Xiao Yi said, Wang Changhong smiled and said, "Okay, since Chief Xiao is concerned about our problems, let's go and have a look first."

Xiao Yi nodded slightly unnaturally, so as not to be seen.

Then, Wang Changhong took him to the sample room inside.

On the way, Wang Changhong also said, "I'll also tell you about the main problem we are facing now."

Xiao Yi waved his hand and said, "No need for the time being."

"Just now in the car, Luo Mingya has told me about the compatibility problems you encountered."

"The main problem you encountered is that the thermal expansion coefficient of the material cannot be well adapted to the materials of other parts, and the high-temperature creep performance also has some incompatibility problems, right?"

Wang Changhong shook his head helplessly: "It seems that the girl has revealed all our secrets."

But what can I say?

After all, they were the ones who drove Luo Mingya out when they got in the car, and asked her to ride in the same car with Xiao Yi.

Then he smiled bitterly and said, "Yes, that's basically the situation."

"To be honest, when we first developed this material, it was only a few years ago, and we celebrated it."

"As a result, we only saw that some basic properties of this new titanium-aluminum alloy were very good, but we ignored the key compatibility issues."

"Compared with another material we used before, this titanium-aluminum alloy is actually better in terms of thermal expansion coefficient and high-temperature creep performance. The most important thing is that the temperature it can withstand is increased by nearly 200 degrees! It has reached an operating temperature of 1200 degrees."

"For turbine blades, 200 degrees is a huge increase, and I believe Chief Engineer Xiao is also aware of this."

"However, the problem is that when this material works at a temperature of 1200 degrees for a long time, its thermal expansion degree is even greater than before."

"So there is a problem."

Wang Changhong sighed.

"Think about it, can we easily give up the working temperature of 1200 degrees? Especially with our updated cooling system, it can directly make the final turbine temperature reach 1700 degrees. At that time, our H-20 will be able to greatly improve its maximum cruising speed and bomb load."

"So we further studied it for several years and wanted to coordinate on it, but now it seems..."

"It's difficult!"

"Difficult, difficult, difficult!"

The chief engineer Wang sighed deeply.

Xiao Yi also shook his head with emotion.

This is the trouble of material research.

The performance of this new material has indeed been greatly improved, but when it is used at the highest performance, such problems will occur now.

As for lowering the working temperature of this new material?

Although this method can solve the problem, the problem is that the effort they spent on researching this material before will be greatly reduced?

So Wang Changhong and his team were completely reluctant to waste the performance of this material, so they have been striving for excellence for several years.

But they couldn't change the structure of the engine itself for this matter.

After all, the structure of the engine itself also serves the stealth performance of the entire H-20 bomber. Once the engine structure is changed, the overall stealth layout will have to change again, and the stealth effect may not meet the original requirements.

Even if it is achieved, the aerodynamic layout will change again, and then the entire aerodynamic layout will have to be reconsidered, which will be even more troublesome.

It can really be said that one hair moves the whole body.

Of course, the main difficulty is that this is a stealth strategic bomber capable of supersonic cruise.

The Americans don't have it, and the Russians don't have it.

The existence of difficulties is inevitable.

"Okay, here we are."

Came to the door of a room, and the sign hanging on it also read the words "sample room".

Walking in, Li Zhenhai next to him walked up and found their new titanium aluminum alloy sample.

"Then this is all the information about this sample."

He took out another stack of A4 paper from the side.

Xiao Yi took them one by one and then looked at the relevant information.

The name of this new titanium-aluminum alloy is TA1203, and 1203 represents its highest working temperature.

Being able to withstand such a working temperature for a long time already represents its strong performance.

You know, the melting point of titanium is only 1668 degrees Celsius, and the melting point of aluminum is only 660 degrees Celsius.

Looking at these materials, Xiao Yi's face showed a thoughtful look.

Of course, in Wang Changhong's eyes, this is the case, but in fact he directly entered the state of material mastery.

He began to understand the various internal information of this material through material mastery.

Now that the material mastery has been upgraded, he can directly start simulating the material even if he does not need the detailed data of the material.

However, with the detailed data of these materials, the simulation will naturally be more accurate.

Soon, after basically understanding the internal structure of this material, he exited the state of material mastery.

"Well, I have already mastered some information about this material." Xiao Yi said: "Are there any other more detailed information? For example, the structure of the engine, and some data from your previous experiments?"

"All of them."

Wang Changhong said, and then took Xiao Yi to get other various data, including the overall appearance and structure of the H-20, and there were also videos.

Looking at these materials, Xiao Yi also became quite interested.

Which boy is not interested in fighters and bombers?

When he saw the promotional video about the H-20, he was also very surprised.

And the sci-fi appearance of the H-20 also surprised him.

I didn't expect that one day, I would be able to personally participate in the research and development of the H-20.

Of course, if you really want to count, he has participated in the H-20 before.

This is to mention the MHT-1, a radar-absorbing material that he accidentally made.

Then, another professor named Chen Weidong from the 603 Institute was attracted to come. Professor Chen Weidong was the leader of the weapons and design group of the 603 Institute. He took the MHT-1 away and said that he would participate in the stealth layout of the H-20.

It was also his first time to participate in the design of the H-20.

Of course, at that time, it could only be said that he participated indirectly, but now he is directly involved.

After getting these materials, Xiao Yi began to analyze them.

Of course, just as he thought before, the problem of material compatibility was not a particularly difficult problem for him.

Because, with his BUFF upgraded to lv7, the two skills of material mastery and perfect engineering can be used together.
