"We definitely support it with our hands up."

Both Liu Zecheng and Liu Jiankun have spoken, and Zhang Gangchuan also asked reluctantly, "In terms of talents, most of the former core technicians of our Kunlun team have gone to Wangwu..."

Zhao Yi said, "It doesn't matter, we don't need anyone for now, if there is a need, I will definitely speak up if I have the cheek."

"OK, no problem."

Gao Mingfu said, "In terms of materials, if you have any needs, you can ask our Academy of Aeronautics to cooperate. In terms of aerospace materials, even the Academy of Sciences is not as good as us."

"Thank you."

Zhao Yi felt the enthusiasm of the review team, and he was in a good mood, but he was most interested in Xia Kaide from Hongfeng Industry. After shaking hands with Xia Kaide, he immediately said, "Leader Xia, I want to Learn about the precision manufacturing capabilities of your Hongfeng Industry."

"Which aspect?" Xia Kaide asked doubtfully.

"In many aspects, for example, the manufacture of the engine shaft, how did you shape the shape of the turbine blades in the prototype you made for Kunlun? If I want to add a subtle hole design on the basis of the hollow mentality, can it be realized? "

"This one……"

"Also, the main material in the front of the inner skin of the engine I designed is titanium alloy? Can titanium alloy be directly molded into a uniform porous structure, that is, to create multiple uniform channels on an area of ​​several square centimeters? ..."

"This one……"

"Do you have the technology of the blisk? Our latest design requires a higher blisk. If it is electron beam welding, it will definitely increase the weight..."

"in addition……"

Zhao Yi continued talking a lot.

Xia Kaide tried to answer at first, but then he simply covered his forehead and called the precision manufacturing expert 'Mr. Zhang' over. "Mr. Zhang, you know more about this than I do. Tell Academician Zhao about it."

Zhang Gong is about fifty years old, with dark and rough skin. He looks like a person who often stays in the factory, but this kind of talent will have been in front of the front-line manufacturing for a long time and understand technical problems in detail.

"Mr. Zhang, hello!"

After Zhao Yi and Zhang Gong shook hands, they began to talk about Seiko's requirements. Zhang Gong answered much more smoothly than Xia Kaide, and he could answer many questions directly.

Once the two exchanged, they didn't know the time.

The others stood by and waited. They were very patient at first, but later found that after an hour, they couldn't wait any longer, but they couldn't bother directly.

Liu Jiankun called Yuan Haitao over and asked in a low voice, "Why is Academician Zhao interested in Seiko technology? Is he going to do research in this area?"

Others also looked over.

Yuan Haitao shook his head and said, "That's not true. Because the design of our group is almost done, the next step is to apply for design finalization and manufacture of prototypes. Academician Zhao wants to learn about Seiko technology and see if the prototype can be manufactured according to the design."

"—?"

Liu Jiankun opened his mouth slightly and was completely stunned.

Zhang Gangchuan laughed out loud when he heard that. He pointed at Yuan Haitao and said, "Captain Yuan, you've made progress after you've been here for half a year! You dare to joke directly when talking to General Manager Liu."

Yuan Haitao turned his head to look over, and said seriously, "Director Zhang, you know, I never joke around at work." His cold and serious look shocked the others.

Are you kidding me?

The design of Kunlun Group [-] is ready to apply for finalization. The next step is to manufacture prototypes?

They looked at Zhao Yi together.

Zhao Yi seriously communicated with Mr. Zhang about precision work, constantly asking 'whether such and such technology is available', 'can such and such parts be molded in such and such a way', and so on.

They all opened their mouths in surprise.

This……

That is not true, is it? !

4Chapter 17 Is a group still necessary?

"The design of the second group of Kunlun has been completed?"

"impossible!"

"The second group has just been established, and there are not many people. I have seen several, but they are not professional in research and development. How can their design be completed?"

"Academician Zhao has researched cutting-edge technology, right? For example, K03B. By the way, I also know that the partition of the combustion chamber is also the latest design. Our team has also done the demonstration and calculation of the new partition."

"That's just two technologies."

"But the second group was originally doing research and development on the basis of the Kunlun engine. It is enough to have a few cutting-edge technologies and a few improvements."

"Could it be that the design that Yuan Haitao said is finalized is just adding two technologies and making simple modifications on the basis of Kunlun? Isn't the Kunlun manufactured in that way?"

"It was the second group of 'Kunlun'!"

"Uh……"

"Right!"

Hearing Yuan Haitao say that the second group was going to apply for finalization of the design, and even prepare to manufacture a prototype, the people next to him quickly spread the news, and many people couldn't help discussing it.

In most people's minds, the second group of Kunlun has just been formed. The purpose of their review team is to take a look at the R&D environment of the second group. The leadership also means to learn about the second group or Zhao Yi's R&D engine. At the same time, see if the second group has any needs in terms of technology, talents, R&D environment, and funding.

result……

The design of the second group is ready to apply for finalization?

"(???(???;)?"

"—!!?"

While other people were discussing in amazement, Yuan Haitao was also constantly questioned. Liu Jiankun asked continuously, "How is it finalized? The design is finalized? Are you sure? All designs?"

Zhang Gangchuan said, "Captain Yuan, are you sure you're not joking? Really? Today isn't April Fool's Day, is it? Have you misunderstood design stereotypes? Or do you have a new design that needs to be reviewed?"

Liu Zecheng, Gao Mingfu and others watched silently, their moods were obviously similar to those of Zhang Gangchuan and Liu Jiankun.

Yuan Haitao was a little irritable when he was questioned, and he said simply, "Manager Liu, Director Zhang, I am very sure that the design you understand is finalized, and the prototype can only be applied for after the design is confirmed. I know this better than anyone else. In charge of the Kunlun No. [-] prototype."

"Uh……"

Everyone else was better. Zhang Gangchuan was so blocked that he couldn't speak. Of course he knew that Yuan Haitao understood the rules, but he still couldn't believe that the second group was planning to finalize the design.

"What new designs have you all made?"

"Compared to the Kunlun machine?"

"Is there any improvement? What's the latest research and development? Or the latest design, Captain Yuan, tell me..."

Liu Jiankun and Zhang Gangchuan no longer asked questions about the finalization of the design, but asked what the latest design was, and what corrections were there compared to the Kunlun engine.

Yuan Haitao was able to answer the last one, "The new design of the deflation valve seems to be made of a hole or something. It directly leads to the air injection port. It is said that it can increase the driving force..."

Then, no more.

Yuan Haitao is not a professional R&D person. He only knows about some new designs. He doesn’t know about other specific changes. Several people kept asking, and Yuan Haitao didn’t know how to answer. Feeling a little awkward.

At this time Zhao Yi came over.

Yuan Haitao breathed a sigh of relief, and hurriedly said to Zhao Yi, "Academician Zhao, you are here, and you should talk about these professional things."

"Oh?"

Zhao Yi still didn't know what was going on.

A large group of people gathered around, but still no one spoke. After waiting for a long time, Liu Jiankun asked, "Academician Zhao, just now I heard from Captain Yuan that your design is ready to be finalized?"

"Correct."

Zhao Yi directly nodded and admitted, but Liu Jiankun didn't know how to proceed. After thinking about it, he asked, "Then, compared with the original Kunlun, is there any modification in the design of your second team?"

"Modification... a lot."

"A lot?" Zhang Gangchuan questioned subconsciously.

"Correct."

Zhao Yi still nodded calmly, "We have revised the whole, every aspect, and some have made a new design." After he finished speaking, he explained, "Because when the Kunlun Group II applied, there was no targeted fighter, and now it is just After the main design is made, only when the target fighter is determined can the parameters, materials and design be changed in order to meet the needs of the specific fighter.”

"Ah... um."

Everyone around nodded.

They understood what Zhao Yi said. For example, the Kunlun engine was aimed at the domestic J-20 fighter. Prototype, because the design has an uncertain upper limit, such as the performance of the combustion chamber and the performance of the turbine group, the higher the better, the higher the performance, to a certain extent, it means the higher the manufacturing cost, and the performance of each component needs to be at the same level. Within a certain range, they can be combined to create an engine that meets the parameter range before it can be loaded on a specific fighter.

The design of the second group of Kunlun is the same.

The performance of each component is not directly matched, and will be affected by design, material, precision technology and other aspects, and there will be considerable differences. At the same time, the performance of each component must have an upper limit of parameters, but the performance parameters of some components High and some components have low performance parameters, so a suitable design must be determined so that each component can be reasonably matched.

After hearing what Zhao Yi said, Zhang Gangchuan laughed angrily when no one else responded.

Zhang Gangchuan is the person in charge of the Kunlun engine group. He felt that it was impossible for the second group to complete the design so quickly. In particular, he said that "a lot of corrections and some new designs have been made." The second group completed a lot of corrections in a short period of time. , and made some new designs. Doesn’t it mean that the development progress of the Kunlun engine unit is slow?

In contrast, the damage is great!

Zhang Gangchuan nodded, and asked vigorously, "Then, Academician Zhao, can you tell me in detail, what new design did the second team make? What kind of corrections did you make to Kunlun?"

"here?"

Zhao Yi doesn't mind talking about it, but the surrounding environment is not very good, surrounded by dozens of people, the design must involve confidentiality.

"Cough cough."

Liu Zecheng coughed lightly and said, "Let's go to the meeting room."

……

A group of people left the operation room of the power engineering laboratory and went to the small meeting room in the mechanical building. Half of the people stayed outside, and those who went in were all the leaders and elites in related fields.

The people from the second group of Kunlun also came.

When everyone was seated in the meeting room, Liu Zecheng said to Zhao Yi, "I am an amateur here. There are also some people like me who don't understand too professional things. Academician Zhao, don't talk too deeply, just Generally speaking, if there are any innovations and improvements, let’s listen to them and take it as an understanding of the design before acceptance.”

Zhao Yi nodded and said, "I'll just talk about it briefly."

The two were talking.

Yuan Haitao found the finalized design documents in the group, held a large stack and placed it in front of Zhao Yi. Zhao Yi flipped through it casually, and suddenly didn't know where to start.

There are so many changes and new designs!

They almost changed the Kunlun engine from the inside to the outside. When comparing the two designs together, it is difficult to see that the design of the second group is based on the Kunlun engine.

Where does this begin?

Zhang Gangchuan seemed to see Zhao Yi's hesitation, and he reminded, "Just talk about the changes and new designs."

Zhao Yi pursed his lips and said nothing. He continued to think about it and said, "Let's start with the main axis."

He raised his head.

Everyone in the conference room looked over.

If the design of the second group is most similar to the original design of the Kunlun engine group, it is the shape of the main shaft turbine blade, the state of mind of the compressor booster blade, and the design of the main shaft itself.

The spindle itself is unchanged.

This is also the only place that is completely consistent, and the shape of the turbine blades and the booster blades of the compressor are all changes and adjustments made on the basis of the original design of the Kunlun engine. Play higher performance.

However, whether the new design can play a higher performance than the original design is not something that can be understood through listening, and very professional calculations are still required.

Zhao Yi said this part, "We have made some changes to the turbine blades and supercharger blades. The turbine blades are originally hollow, which is a good design, but there are still some minor problems..."

"The modified turbine blade, under the same material properties, has the same weight as the original design, and the performance will increase by 13.00% to 15.00%."

"The supercharging vane is changed to a multi-arc and hole-connected design, which can increase the supercharging effect under strong winds, and cooperate with the stator..."

"After the modified supercharging blade, the supercharging efficiency is between 11.00% and [-]%."

"These two conclusions are obtained through our repeated calculations."

After Zhao Yi finished speaking, he looked at everyone.

Several people looked at Zhang Gangchuan. Zhang Gangchuan must have an understanding of the shape of the main shaft blades, and he must have done in-depth research on the relevant aspects.

Zhang Gangchuan frowned and thought carefully. What Zhao Yi explained just now was not detailed, he just talked about how to improve, but the overall idea and direction were still stated. He thought for a long time and still couldn't make a decision. Zhao Yi said Whether the method can increase performance really requires very professional calculations to know.

Some people focus on something different.

For example, Liu Zecheng and Liu Jiankun found that Zhang Gangchuan was silent and looked at each other for affirmation.

Now the second group’s design of the shape of the main shaft blade does not dare to say that it can improve the performance by 100%, but it must have certain reference and value, otherwise Zhang Gangchuan must be aware of it immediately, and then consider Zhao Yi’s own mathematics level to improve performance. It should be fine.

Talk about computing?

Who can compare to Zhao Yi!
