Section 313

Although Xiao Yi could start the research at any time, Wang Changhong told him later that the research was conducted in another material research institute under the military, near Jinling. After all, Jinling is the base of the Eastern Theater Command, and there are naturally some research institutes nearby.

But Xiao Yi obviously couldn't stay in the research institute all the time. After all, he still had to attend classes at school, and as the director of the Science Island Laboratory, he also had a lot of things to do. In addition, he also had his current position as the general consultant of the National Fusion Company. Sometimes the company would have some technical inquiries, and he might need to go to the site occasionally.

Not to mention, now, his three students are about to graduate, and before they graduate, he, the teacher, of course, still has to watch.

So, in the end, Xiao Yi decided to go to the research institute first to at least know what kind of material they need now, and then see where the research progress is, and finally think about how to help them solve the problem.

In aircraft engines, material compatibility is indeed a very important performance.

Material compatibility refers to whether harmful physical or chemical reactions will occur when different materials coexist in a specific environment, whether they will lead to a decrease in material performance or structural damage. It reflects whether each material in the entire material system can effectively exert its own stability and reliability.

This problem exists in various projects, including building a house, and also considering the compatibility between the materials used in the house. Of course, in modern projects, these materials have already had a systematic conclusion, so just use them.

However, for a project like the H-20, it is destined to require more detailed considerations in this regard.

As a new strategic bomber in the 21st century, the performance of the H-20 must show its latecomer advantage.

For example, the US B2 bomber has a very strong stealth capability, but its speed is very average, while the Russian Tu-160 is very fast, with the fastest speed reaching Mach 2.05, but it completely abandons its stealth capability.

So the H-20 has both stealth and supersonic cruise capabilities, which is truly all-round.

But...

For Xiao Yi now, the compatibility problem seems to be quite easy to solve.

...

After leaving the Science Island Laboratory and getting in the car, they headed straight to Jinling.

Liu Cong was a secretary and a driver in a car. As the director of the National Science and Technology Bureau, he certainly had a full-time secretary and a full-time driver, and the car he was assigned was also an A6.

Then came Wang Changhong and his team who drove over from Jinling. They drove a military vehicle directly, and the driver was also a soldier.

Xiao Yi took Wang Li and got on his tram.

As for Luo Mingya, she also got on his car. It was not that she didn't want to sit with Wang Changhong and Li Zhenhai, but when she wanted to sit, Wang Changhong and his team pushed her out and asked her to sit with Xiao Yi. They were two young people.

Xiao Yi didn't care, but Luo Mingya was a little helpless. She always felt that there seemed to be some encouragement in the eyes of Chief Engineer Wang and Team Leader Li?

Sit if you want to.

After getting in the car, Luo Mingya was surprised by the interior of the car and the thick door when she opened it just now.

"Why is your car a little different from the Diaby Hua I usually see?"

She asked in confusion.

Xiao Yi smiled and said calmly: "This is a gift from Diaby. It is customized and it is indeed a little different."

His electric car is Diaby's latest flagship model, named [Hua]. It is a new model after the major dynasty models.

It is equipped with a brand-new lithium-sulfur solid-state battery. After being fully charged, it has a range of 2,500 kilometers, which directly matches the range of its previous hybrid models. Moreover, compared with the emission problems that hybrid cars still have, such pure electric cars have no emission problems at all.

Of course, [Hua] is also the world's first lithium-sulfur solid-state battery car, and its starting price is relatively high. The starting price of the lowest configuration is 499,900, and the high configuration will be higher.

But even so, this car has been sold out.

As for Xiao Yi's car, it was given to him by Diaby when he launched this new model. It is more advanced than the highest configuration on the market and is specially made.

In addition to the fact that it looks no different from the [Hua] in appearance, the materials used for the entire body of the car are the best, and naturally it also has bulletproof performance.

It is said that when building this car, Diaby also invited experts in military bulletproof vehicles to provide guidance.

The car door alone is nearly three times thicker than ordinary car doors, and the car windows are naturally thickened.

The defense capability can be said to be basically full, and in terms of power, it is also customized, with a maximum speed of 280. As a bulletproof electric car, this speed is already quite fast.

In addition, there are quite a lot of other black technologies.

As for the interior, there is naturally no need to say more, even the starry sky roof.

In short, this is a super luxury car that only looks like [Hua] in appearance, and the overall cost is not less than 10 million.

Hearing Xiao Yi's words, Luo Mingya blinked, and then said with emotion: "As expected of our Chief Engineer Xiao! A man richer than Musk."

Xiao Yi laughed for a moment and said, "Why are you talking like this? You're not like the female bully in the School of Materials Science and Engineering."

Luo Mingya rolled her eyes and said unhappily, "Don't slander me. Don't mention the things of the past."

Xiao Yi nodded with a smile.

Then, he said, "But I didn't expect you to be doing research in the H-20 project."

Luo Mingya smiled and said, "I didn't expect that nuclear fusion would come out before the H-20."

Xiao Yi said, "Do you still remember the bet?"

"Of course I remember." Luo Mingya shrugged, "But I can't leave now, unless you can dig me out from Chief Engineer Wang and Team Leader Li."

"Chief Engineer Wang thinks so highly of you?" Xiao Yi raised his eyebrows. After hearing what Luo Mingya said, could it be that the face of Chief Engineer Xiao was not enough to dig out a researcher who was not the leader of the research group?

Luo Mingya said: "Chief Engineer Wang has a good relationship with my grandfather. I once studied with Team Leader Li for a period of time. He is my teacher. Now I am a researcher in the turbine blade material group. I have previously proposed a solution to optimize the surface consistency of the blade material. Therefore, I am probably also involved in the issue of material compatibility."

Xiao Yi raised his eyebrows and smiled: "It seems that the female bully is an important figure wherever she goes."

"I said you are not allowed to mention it again." Luo Mingya said unhappily: "What's more, now that Chief Engineer Xiao is here, no matter how important the person is, he will seem unimportant, right?"

Xiao Yi laughed: "I'm not here to fight for power and profit."

Luo Mingya chuckled: "That's true."

After that, there was silence in the car for a moment.

There was no noise coming from outside. The car was very quiet. The thick enough body material could prevent any sound from coming in. Of course, some horns outside the car could be collected by external high-sensitivity microphones and transmitted to the speakers inside the car or the driver's headphones, so as to ensure that the judgment of some external situations would not be lost because of the inability to hear the outside world.

At this time, Wang Li, who was responsible for driving, was wearing headphones.

However, he would occasionally glance at the two people in the back row from the rearview mirror. Although there was a window partition design, Xiao Yi had never used it.

His bodyguard, who was sent here, not only had to protect Xiao Yi on weekdays, but also examined all people who approached Xiao Yi.

Of course, he was not examining Luo Mingya now. After all, she was a researcher who could participate in the H-20 project, and she might have been examined long ago.

He just thought of a more secret task he had taken before, which was to see if there were any women around Chief Engineer Xiao who tried to get close to him, and some women who were close to him.

The former are naturally quite a lot. Xiao Yi is single and unmarried. He has great talent and wealth, so there are naturally quite a lot of women who want to get close to him.

Fortunately, they don't have to worry too much about such women. Their Chief Engineer Xiao can do everything he can to push these women away and make them give up the idea.

As for the latter, to be honest, Wang Li has rarely seen women of the same age who are close to Xiao Yi.

This woman called Luo Mingya is indeed the only woman of the same age he has seen in such a long time who can talk to Xiao Yi.

Could it be that the things that the higher-ups have been worried about have now been settled?

For a great scientist like Xiao Yi, the marriage problem is still very concerned.

Once the position is high, marriage, which is originally a private matter, will also become something that others have to care about.

The leaders naturally hope that Chief Engineer Xiao can get married in China as soon as possible and find a Chinese wife. With a concern in his heart, he will be more stable.

However, the leaders also hope that Chief Engineer Xiao can find a good wife, so that the family will not bring some negative influence to Chief Engineer Xiao in the end.

So regarding this matter, the leaders told Wang Li to take good care of him in normal times.

But now it seems that this woman with the surname Luo is very suitable.

"Well... it seems that there is a solution."

Wang Li grinned and continued to concentrate on driving.

At this time, Xiao Yi also spoke again: "By the way, take advantage of this time to tell me about the problems you encountered."

Luo Mingya nodded, and then began to talk.

"Because the H-20 is a stealth strategic bomber, and in order to ensure that it has a strong enough stealth capability, all designs need to be compatible with its stealth capability."

"However, the thermal expansion coefficient of the new titanium-aluminum alloy blade material we have developed does not match the materials of other engine components..."

As Luo Mingya gradually spoke, Xiao Yi also understood where the problem they encountered was.

The coefficient of thermal expansion refers to a physical quantity used to measure the degree of thermal expansion of solid materials. It indicates the relative change in length or volume of an object per unit length or unit volume when the temperature rises by 1 degree Celsius.

In the high-temperature working environment of aircraft engines, the problem encountered by Luo Mingya and his team is that the expansion amplitude of the new material blade is greater than that of other parts, resulting in a reduction in the gap between the blade and the casing and other parts, and even interference friction, which affects the normal operation of the engine and increases the risk of failure.

Although they have made many adjustments, they have not been able to reach a level that satisfies them.

After all, turbine blades have a great impact on the performance of aircraft engines.

As the saying goes, aircraft engines are the crown of human industrial history, and turbine blades are the pearls on the crown.

Once the composition changes, it will more or less affect many other performances.

In addition to this problem, the creep performance of new materials at high temperatures is more or less incompatible with other materials.

They are reluctant to completely change the idea of ​​​​the new blade material. The first is to waste time, energy and cost, and the second is that the performance of this new material is so strong that they are reluctant to give it up.

So now they are stuck here, but they are not in a hurry. After all, they have plenty of time to choose a plan, and their task is not time-limited.

But who knows that nuclear fusion technology suddenly emerged and had a great impact on the international situation.

So, the person who tied the bell must untie it, and they found Xiao Yi who came up with nuclear fusion and indirectly changed the international situation.

Xiao Yi was helpless after hearing this.

So, this matter is still because of the nuclear fusion he came up with?
