Rule system

"The design of the two groups of Kunlun is completed?"

"impossible!"

"The two groups have just been established, people are not a few. I have seen several, it is not professional research and development, how can their design be completed?"

"Academician Zhao studied cutting-edge technology? For example, K03B, right, I also know the partition film of the combustion room, and the latest design, we also made a new partition film argument, calculation."

"That is just two technologies."

"But the group was originally developed on the basis of the Kunlun engine, there were several cutting-edge technology, there were several improvements."

"Does Yuan Haitao said the design is just on the basis of Kunlun, adding two technologies, making simple modifications? Do not still still Kunlun?"

"It is the two groups of 'Kunlun'!"

"Uh……"

"Right!"

I heard that Yuan Haitao said that the two groups were prepared to apply for design, and even prepared a sample, the people next to them quickly came out of the news, many people couldn't help but discuss it.

In the impression of most people, the Kunlun two groups just have just been established. They make up the purpose of the review group, that is to take a look at the research and development environment in the two groups, the meaning of the leadership, understand the two groups or Zhao Wei research and development engine The idea, while looking at the two groups in technology, talent, R & D environment, and funding, etc.

result……

The two groups are designed to apply for a fixed type?

"(꒪ꇴ꒪ (꒪ꇴ꒪;)?"

"- !!?"

When other people are surprising, Yuan Haitao has also been questioned, and Liu Jiankun asked in a row, "How is a fixed shape? Designed? Are you sure? All Design?"

Zhang Gangchuan said, "Yuan Captain, you are not a joke? Really joking? Isn't it a April Fool's Day? Are you a new design? Is there a new design, need to review it?"

Liu Zecheng, Gao Mingyi and others are silent, and mood is obvious and Zhang Gangchuan. Liu Jiankun is almost.

Yuan Haitao was asked for some irritability. He very simply said, "Liu Yi, Zhang Director, I am very confirmed, it is the design type you understand, determine the design to apply for the model, this is more clear, I was Responsible for Kunlun 2 prototype. "

"Uh……"

Others are still better, Zhang Gangchuan is blocked, he certainly knows that Yuan Haitao understands the rules, but still can't believe that the two groups are ready to design.

"What new design you have done?"

"Compared with Kunlun machine?"

"Is there any improvement place? What is the latest research and development? Or the latest design, Yuan captain, you talk about ..."

Liu Jiankun, Zhang Gangchuan no longer chased the design of design, but asked what the latest design was compared to the Kunlun engine, what amended.

Yuan Haitao is able to answer the last, "the new design of the custom door seems to be a well-known, directly to the jet, it is said to increase the driving force ..."

Then, no.

Yuan Haitao is not a professional who specializes in research and development. He just understands some new design. If there is any other change, I don't know. Several people have been questioning continuously, and Yuan Haitao does not know how to answer, he is very difficult to be in the same place, I feel a bit embarrassed.

At this time, Zhao Wei came over.

Yuan Haitao had a long tone, and he quickly said with Zhao Wei. "Academician Zhao, you can come over, these professional things, or you speak."

"Oh?"

Zhao Wei still doesn't know what is.

A large group of people surrounded, but no one speaks, wait for a long time or Liu Jiankun asked, "Zhao's unscrupulous, I just listened to Yuan Captain, said, your design is ready?"

"Correct."

Zhao Wei nodded directly, but Liu Jiankun didn't know how to continue. He thought about it, "So, the design of you, is there any modified place than the original Kunlun?"

"Modify ... a lot."

"A lot?" Questioning the ideology of Zhang Gangchuan.

"Correct."

Zhao Wei is still calm, "we have made a whole correction, aspect, and there is a new design." He said, "When the Qunlun two groups, there is no aiming fighter, now just Make the main design, only the aiming fighters can be made to perform parameters, materials, and design changes, in order to meet specific fighter needs. "

"Ah ... Well."

Everyone is nodded.

They understand Zhao Wei's meaning, like Kunlun engine aiming is a domestic J-20 fighter, designing is determined according to the demand for the engine according to the domestic J-20 fighter, and then produces corresponding accessories, and manufactures corresponding The prototype, because the design is uncertain, such as combustion chamber performance, turbine group performance, the higher the better, the higher the performance, the higher the manufacturing cost, the performance, the performance, all Within a certain range, it is combined to create an engine that meets the parameter range can be loaded on a specific fighter.

Kunlun two sets of design is the same.

The performance of each component is not directly supporting, which will be affected by the design, materials, and precision technology, and there will be a small difference, while each component is performed, there is certainly a parameter, but some components performance parameters High, some component performance parameters are low, and a suitable design must be set, allowing the various components to match reasonable.

After hearing Zhao Wei's statement, others have not responded, and Zhang Gangchuan is ignorant.

Zhang Gangchuan is the person in charge of the Kunlun engineer. I feel that the two groups have finished designing, it is impossible, especially the amendment, some new design ', two groups have completed a lot of fixes. I have made some new design, not to say that the research and development progress in the Kunlun engineer group is slow?

Contrast, the damage is great!

Zhang Gangchuan headed his head, asked for hard, "So, the academician Zhao, you are talking in detail, what new design did two groups? What is the correction of Kunlun?"

"Here?"

Zhao Wei did not mind, but the surrounding environment was not very good, dozens of people were surrounded, and the design will definitely involve confidentiality.

Cough. "

Liu Zecheng took a cough, open mouth, "Let's go to the conference room."

......

A group of people left the operation room of the power engineering laboratory. In the small meeting room of the mechanical building, some people left outside, they all in the leadership and related fields.

People in the Kunlun group also came over.

All people are sitting in the conference room, Liu Zecheng said to Zhao Wei, "Here, I am outside the line. Some people are like me, don't understand too professional things. Zhao Academician, you don't talk too deep, only Generally speaking, what is innovative, improved, we listen, it is a understanding of the acceptance design. "

Zhao Wei's head, "I just said."

The two said.

Yuan Haitao found a document designed in the group, holding a big pair in front of Zhao Wei, Zhao Wei turned over and suddenly didn't know where to start.

Change, there are too many new design!

They almost changed the Kunlun engine from the outside, and the two designs were contrasting together, it is difficult to see the design of the two groups, which is based on the Kunlun engine.

Where should I start saying?

Zhang Gangchuan seems to have seen Zhao Wei's hesitation, he reminded, "only to change the place, there is new design."

Zhao Wei did not say anything, he continued to consider it, "said it from the spindle."

He lifted his head.

Everyone in the conference room came over.

If the design of the two groups is most similar to the original design of the Kunlun engine group, it is the main shaft turbine blade morphology, and the compressor booster blade mentality and the main shaft itself.

The main shaft itself is not changed.

This is also the only place in which the turbine blade, the pressurized blade of the turbine blade, is the change adjustment made on the original design foundation of the Kunlun engine, which is the technical correction, add the design of the hollow hole, so that the blade can Give a higher performance.

However, the new design is better than the original design, and it is not a very professional calculation by listening.

Zhao Wei said this, "We have changed the turbine blades and boost blades. The turbine blades are originally hollow mentality, but it is a very good design, but there are some small problems ..."

"After the changed turbine blades, the same material properties, weight and original design are comparable, and performance will increase by up to five percent."

"The booster blade, the design of the multi-arc channel and the hole connection can increase the supercharged effect under strong wind, with the stator ..."

"After the change in booster, the boosting efficiency is between nine to 11%."

"These two conclusions are all calculated repeatedly."

Zhao Wei said to look at everyone.

Several people looked at Zhang Gangchuan, Zhang Gangchuan affirmed the form of the spindle blade, and there must be in-depth research on the relevant.

Zhang Gangchuan is wrinkled and carefully thinking. Just now, Zhao Wei's explanation is not meticulous, but it is just how to improve, but the overall thinking, direction is still said, he thinks that it is half a day or not, Zhao Wei said Whether the method can increase performance and do very professional calculations to know.

Some people pay attention to the points.

For example, Liu Zecheng, Liu Jiankun, two people found Zhang Gangchuan silence and did not speak, and there was a thing about it.

Now the design of the main shaft blade form is not to say that 100% can improve performance, but it must have certain reference and value, otherwise Zhang Gongchuan has been noticed in the first time, and then considering the mathematics level of Zhao Wei itself. Performance should be no problem.

Talk about calculations?

Who can compare Zhao Wei!

Yuan Haitao, Sun Lei, Wang Zhi, etc. are sitting on the side, and their points are also different.

Sun Lei looked around and saw it. "This is what Zhao is designed. When will we calculate this, armed this?"

Wang Zhiguo's mouth, "I don't know all, we have completed the turbine blade, the improvement of the pressurized blade ..."

Yuan Haitao, "This is what Zhao is doing. You certainly don't know, others can not use it. Zhao is the most top mathematician, do you ask other people in this regard?"

"Right."

"However, blade design is not just mathematics ..."

When the few people were talking about, Zhao Wei said the latest design, which is the compromine stability solution. He opened the design document, and he felt some mouthful of dry tongue, and immediately looked at this side. He said, "Sun" Lei, you are responsible for this piece, let's talk about it. "

"I?"

Sun Lei pointed to himself and surprised.

"Of course, you are responsible for this piece." Zhao Wei said very seriously, "said that it is said to let the door."

"it is good."

Sun Lei stood around and saw it, still a little nervous, he walked to Zhao Wei, and I started explaining the document. "We have made a new deflational door design for stability, completely changed the original simple The piston design is used in a multi-hole discharge method. "

"The inlet of the engrave of the body corresponds to the pressure press, each of the outer mouth of each hole corresponds to the final exhaust port ..."

"We designed the final exhaust port in the periphery of the jet, and changed the outer form of the compressor ..."

Sun Lei has started to have some nervous, but also wrong twice, it seems to have found a state, repeatedly said, one is more than ten minutes, designed from the hole piston, has been designed to the outer layer of the compressor, Includes the second airway, isometed to change the shape of the outer layer of the engine.

This design is very novel, the core is that the outer form of the Confair Pistons and the compressor package combustion room, Sun Lei is just a simple painting, let several people in the conference room bright, including Zhang Gangchuan amazed, "Don't hone! "

"This design, it is not easy!"

"Is Zhao Academician?"

After Sun Lei introduced, Zhang Gangchuan couldn't help but ask, Zhao Wei shakes his head, "" The first is to come from Zhou Qing. "

"Who is Zhou Qing?"

"I do not know?"

Don't say that it is other person, even Zhang Gangchuan doesn't know Zhou Qing, Zhou Qing is just a small engineer of the prototype, which can be said to be the technical blue collar of the R & D group. It is not easy to remember the name.

Zhou Qing was mentioned as an excitement when he was mentioned, and he raised his hand, "I! I!"

Everyone else has seen it.

At this moment, Zhou Qing reached the peak of life, all the leaders of the conference room and the elite R & D personnel, all of them were aligned with him, he even cleared the scorpion, thinking about what to say.

Liu Jiankun is interested in asking, "This design is very innovative, is there any other?"

All persons are coming to the next technical issue.

Zhou Qing returned back.

In fact, it is similar to the new design, it is almost the same here. It is enough to surprise everyone, even Zhang Gangchuan can't say anything, I think there is another of the K03B performance, it is determined to apply to design a design, design, can be said to be the Kunlun engine. It has already been very different. Unsure is just, design, improvement is correct, follow-up to the stage of acceptance design, must have elapsed in detail.

However, the people who came to the examination team did not expect that the report of the two groups of Kunlun only said that the main changes, and some included changes have not been finished. Next, Zhao Wei let Yuan Haitao, Li Rongmao, design, compress the combustion room The aperture piston and the vane type of the blade are elaborated, followed by a change in the front section of the spindle.

The front section of the spindle is integral, but not in the 'design acceptance' range, there is no aimed aircraft model, which is to determine the engine requirements, the front sector blade and the fan are uncertain, the turbine fan engine, different The front sector leaves and fans drive the same primary core components, which can be placed in two applications.

For example, the front sector and fan design will have a lot of resistance, which greatly reduces the transition ratio of the engine, but it can greatly reduce fuel consumption, which can be used on civil aviation passenger aircraft.

on the contrary.

The demand for the warplate to the turntile engine is the smaller the front sector and the fan, the smaller represents its own resistance, the second airway, the third wind center is best not to use, you can produce huge thrust, Support for supersonic or even a few times of sound.

The difference is here.

Zhao Wei was another change in the previous sector and fan. He mainly adjusted the fan form and the deflection angle. The big fan has also added a thinner fan, and the front sector behind the back is also corresponding. Two pieces, "This matching can produce a greater moving pull, not to increase the weight, because the front sector blade is small, I am discussed with the material group, and some new materials may also be possible. reduce weight."

Performance improvement is the key.

Regardless of whether the engine is used on what aircraft, you can directly improve performance design, it is definitely available.

Zhao Wei said the fan improvement problem, it did not cause more reactions, because the people in the examination team were surprised enough.

"ended?"

"Nothing?"

Liu Ze became a react around Mu, he probably was the most uncomfortable in the conference room, because only his understanding of the air engine, some places are like listening to the sky, but also know the design of the two groups Shocked.

He is clear -

Zhao Wei led two groups to the Kunlun engine made a huge change, and even finished all from all from the other, including the core turbine group, combustion chamber, compressor, but also two-layer engine skin, the front fans Wait, I want to find a place where there is no change in the engine is not easy.

Therefore, do not have to worry about the problem with less design and change, but it is more designed, and the manufacturing is more troublesome.

This Liu Zecheng still knows.

If you want to have fewer changes, there are experiences in making Kunlun engine, some parts can be used directly, all new design, and it is much more difficult to manufacture.

"No wonder the academician of Zhao first begins with the technical skills, it is so!" Liu Zecheng fully understood.

At this time, Zhang Gangchuan is the most embarrassing.

When he listened to the design introduction of the Kunlun two groups, he also listened to the taste, but also sent it to some design, but now he realizes a problem, the Kunlun two groups only used a short time, even less than three At the time of the month, all the design work was completed, and the steps to apply for the manufacture of the prototype were also directly entered, and the progress was not catching up with Kunlun?

In addition, the design of the two groups is also very high end.

If the design is passed in the subsequent design, their design has passed, and then the corresponding prototype ...

"Is there any need for our group?"

Zhang Gangchuan suddenly became a little confused. He had a crisis of 'lost work', and even couldn't help but think of it. "Do you want ... and the two groups of Kunlun, have developed two groups of design?"

"No!"

He shook his head right away.

The Kunlun engineer has insisted that so many years, it is difficult to have a prototype, and the progress of fighting with the fault is also very gratifying, directly giving up really accepting.

"Maybe the two sets of prototypes, more than Kunlun fault!" This thought, his mood was calm down.
