Rule system

When discovered in the field of their best, it has been made for several years, and the result is taken by a foreman, only for half a year, surpass, what is the feeling of inner?

Now Li Jianming feels feeling, he knows that the Wars-1 completed the design, submitted the application for acceptance, the aviation group also solemnly organized the organization review team, and his first reaction was unwilling to believe.

"impossible!"

"It has completed the design for half a year. How is the aircraft design? The design of the five-generation machine? What is the performance of the five generations, and now there is still a debate, directly say that it is a five-generation machine?"

"The highest amount of gold is now four generations. It can't make a five-generation machine in a short period of time, and it is impossible for a few years. It is not possible!"

This is the heart of Li Jianming.

Although Li Jianming has been designed J-31, because the group is too high for the five generations of parameters, even some ***-type and F-35, he can't complete design work, every part of the design must Considering a lot of factors, you need to carefully discuss it.

The WZ-A1, WZ-A2 engine design, let Li Jianming have seen a point of hope, the engine performance, the design of the fighter performance will also improve, but I don't want to eat a fat man, he thinks J The design of -31, it is also necessary for a minimum, two years, can be truly applying for design acceptance.

At that time, the design would not be very perfect, but to convince some people, reduce the performance requirements of the five generations, and the F-35 is unrealistic, but as long as there is high performance engine support, it has reached the four generations of menometers. Great.

This is the judgment of Li Jianming.

Now I heard that the Wark -1 design application was accepted, he could not accept it.

"Maybe just because of Zhao Academician?"

"The Group's high level thinks should be careful, not how good is the Wars-1 design?"

"Yup!"

"This should be!"

Li Jianming felt the truth.

In fact, there are many people with similar opinions with Li Jianming, especially the Shencheng Aircraft Research Institute, Wucheng Aircraft Design Institute, and two research institutes specialized in aircraft design work, and it is very clear for high-end fighter design.

This is not a solution, but to surpass domestic existing information, design technology, leapfrogging to complete a higher generation design, they do not have the data in the transitional stage, no related experience, directly complete the leap design, Don't say something difficult, think about it, think it is impossible.

not to mention……

Half a year?

"Junny?"

"Unless I see the design, I will never believe this kind of thing." Some people assert.

Some colleagues say that Li Jianming is safe, standing in its own point of view, he doesn't want to see a set of gorgeous five-year machine design.

That represents his failure!

In fact, Li Jianming still looks forward to seeing something, just like Yang Cong, I feel that the design is impossible, but to Zhao Wei's research and development capabilities, he feels that Zhao Wei participated in the aircraft design. Work, it may have a bright spot, maybe this highlight, causing the group's high level attention?

Because of this, Li Jianming decided to go to see it.

When he said, when he said, Li Jianming didn't make a hand, and he also said that he said, "I will go, the same design five-generation machine, even if you want to lose."

Although this is said to be said, how many authenticity is hard to say.

the other side.

Yang Cong watched a few hours in the office. When he arrived in the evening, he felt a burst of stomach, he was still unfained to stop.

He looked most of the design information.

After a few hours, I definitely not look at most. When I started, he still seriously saw that every detail had repeated scrutiny, even picked up the paper and verify the calculation, and later looked at a few pages, he found no Wrong place, simply browsing each part is designed.

Yang Cong took the appearance of the Wars-1 design, and before and after before and after, he felt that his stomach was screaming, and he still stopped and stretched a lazy waist, and found Liu Jiankun sat next to it. I still put it on it.

"Liu Qi, really time! I am hungry!" Yang Cong said a stop, and I feel a little dizzy.

Liu Jiankun has been busy in service, laughs, "I see that you are all devil, I will keep it, how?"

"Unique, there are many innovations, and the argument is rigorous, just some calculations are very complicated, I am not sure whether it is correct."

Yang Cong judged a sentence, then sitting on the table, picking up a few mouthfuls of rice, and not adding a word, "I still said, very beautiful!"

"Yeah!" Liu Jiankun sighed.

Such a scientific design plan, just look at the appearance, but specifically, it is necessary to see how professional people say.

Yang Cong said while eating, "I didn't finish reading, but I also gotten over again, the most impressed is that there are many automatic control components in the design."

"Those components that change their minds according to the aircraft, including wing, tail, etc., theoretically basically no problem, in fact, this area is not necessarily questioned, Zhao Academician is a mathematics expert."

Liu Jiankun listened to a serious nod.

Zhao Wei is a recognized mathematics NO.1 in the world. The calculated part is not to question, but he is more than just mathematicians, WZ series engine design, enough to prove that he is also the top in terms of kinetic, mechanical physics. .

"I think, only look at the design of the appearance, even if the F-35 is compared, it is estimated that it is not possible."

Yang Cong sighs to make a comparison.

"Is it so powerful?" Liu Jiankun listened to the surprised, "" Is it better than F-35? "

"At present, this design is going to exceed F-35, and the least theoretically transcendence, but there is a little ..."

Yang Cong said very seriously. "I found the biggest problem of design, this problem does not resolve, this design may be put on the database, more than ten years, and take it out for decades."

"what is the problem?"

Liu Jiankun became more serious, serious, Yang Cong is the top three aircraft designer in China. He said that major issues have been found, maybe it is true.

Zhao Wei did studying is really very powerful, but he is not a professional aircraft designer, maybe in the design, there have been no attention, affecting the entire design problem.

Yang Cong pulped up in his mouth, and did not panic, the cup of tea, it was obviously some of the meaning of some selling, he has been smiling, there is a kind of feeling of 'major confidential'.

Liu Jiankun is not anxious, and it has also been helped to help the tea, introduce Yang Cong to the top gross edge here.

finally.

The two returned to the seat.

Yang Cong raised a tea cup and said with a smile, "the overall control has problems!"

"There are many automatic controlled components in this design, and it is very unique, but it is difficult to achieve overall coordination if they are owned by their autonomous direction."

"For example, when the plane is rapidly pulling from the dive turns, the folding wing will start, but the flaps will not start quickly, the automatic changes of the tail will also drag the power of the top, in which case Automatic transform parts, many will become dragged, maybe it is not ordinary design ... "

"So I want this design to play ideal effects, I have to have a smart main control system!"

"this is a must!"

"But according to what I know, even the electronic control system of the international top fighter, can also achieve flexible control of so many parts, which involve very complex operation, and domestic ..."

"Balabara ~~~"

Yang Cong said a lot of piles, in the case of selling his own knowledge, after a while, he found that Liu Jiankun's look is somewhat, some is still unfained to stop, asked, "Liu Zheng?"

"Cough, cough ~"

Liu Jiankun took the smile of his mouth and went to the sofa to come up with a document. "What should you say?"

Yang Cong took a document to see a topic, "Intelligent Control System?"

He opened the two pages, the expression was completely stiff, and some realized the embarrassment of 'social death', looked up and looked at Liu Jiankun, smile stiff, "It turned out ... Zhao's inter think about it."

"Ha, Ha, Ha ~~"

the other side.

After Zhao Wei submitted the design and acceptance of the report, he will wait for the news.

He is very busy.

The Wars-1 design work is completed, the next is to wait for design acceptance, determine WZ-A1 engine aiming to fight Eagle -1, then the manufacturing engine sample, first make the engine to start manufacturing the fighter testing machine.

The engine's moderator works, it can urge the red wind industry. He and the red breeze industry have cooperated. The things manufactured by the prototype have been opened all the way, but because it is not officially approved by the superior, it can only design the mold internally, formulate the plan.

These are all working in advance.

When involving the red breeze industry, we must pay attention to the spindle development of the red wind industry.

The red wind industry has sent a lot of information.

Zhao Yu took time to see the technical information related to industrial spindle manufacturing, the content of the information is much, including not only the spindle manufacturing technology of the red wind industry, but also information, parameters, etc. related to the spindles, machine tools, precision. Wait.

For the main shaft-related research and development design, these must be well understood.

It is the advantage of seeing manufacturing technology. There is no obscure theory. The technical information is said to Zhao Wei. It is not much different from the philosophy. It is to look at the design, materials, parameters, etc., carefully look at it. Stay, don't use care, think about it.

Therefore, he read the amount of information very fast, spent about more than a week, and has a general understanding of the research and development of industrial main shaft technology and the red-breeze industry.

Industrial spindle, spindle, including many types, is common to the belt-type spindle, spindle gear, as well as direct-coupled spindle motor spindle.

The belt drive spindle so widely on the market, from small to large machining centers are used, a belt-type spindle speed does not exceed 8000, the assembly is relatively easy, many more vibration small gear, the faster the speed the greater drawback is noise, and difficult to control belt tension.

Many large, medium-sized CNC machine, using the spindle gear shift mode, the deceleration gear by a few, to expand the output torque to meet the requirements of low speed when the output shaft torque characteristics, and more powerful than the belt drive spindle, but the disadvantages are also obvious, noise and vibration are very large.

The main advantage is a powerful, big drawback is the noise and vibration.

Direct spindle oriented to the processing of small parts, the faster the speed the smaller the cutting force, the more extensive industrial uses, but also a lot of advantages, such as the relative speed of the belt type is much faster, but the correction of the direct coupling spindle has a very high requirements.

Red Wind industry for several spindle has production, research and development, but also a certain domestic market share, but their main spindle technology research and development, and put them on the latest model of electric spindle.

Is the latest electric spindle spindle spindle speed of 50,000 rpm very high energy, wherein an electric motor spindle drive structure, and the main spindle head is greatly simplified structure, effectively increase the rigidity of the spindle member, the international many large machines, including ultra-precision machining CNC machines, are used for fast speed, easy control spindle.

Technical difficulties spindle, the disadvantage is that it is excluded, for example, sealing and precision spindle, spindle speed will bring more rapid wear, ultra ensure sealing, it is possible to reduce the possibility of damage , while the accuracy is the key to the key, only a certain degree of accuracy, in order to use in the fine machining member.

"So the focus should be placed on research and development of electric spindle, red wind industry main research spindle, but they produce spindle, even the self-development of domestic machine tools do not have access ......"

Zhao Yi sigh and shook his head.

You can see from here, the domestic high-end manufacturing industry and the gap between the international and domestic companies use most of the leading manufacturers of machine tools are imported from abroad over, and the top of the machine tool industry, and even the purchase will be subject to restrictions.

Domestic production of machine tools from research, not for leading high-end manufacturing industries.

For example, most electronic chip production requires precision.

This is the field of ultra-precision machining, completely monopolized by foreign companies, machine tool spindle technology does not mean that, but it is an integral part of the core components of the machine.

"Red Wind industry to grasp the electric spindle manufacturing technology, to create the most from the high-precision spindle, estimated worse on two generations, three generations, or even more, right?"

Zhao Yi is somewhat uncertain, but he can not wait to start doing some research and development, not just want to help the domestic high-end manufacturing technology development, but also want to try the effect of "derived rate".

When the real test "derived rate" effect, he discovered a problem, much simpler than the spindle motor, but also includes several parts, he found a whole can not be used "derived rate", only a portion of a part of Come.

Then……

Usage "derived rate" will consume 68 points coins learning, whether to use?

Zhao Yi prompted by the system are some ignorant, the effect is "derived rate" seems to be very good, but learning coin consumption is also very alarming ah.

In this way, let the red wind industrial electric spindle technology upgrade generation, you need to consume hundreds, thousands of learning coins?

"It seems to be a little loss ..."

Zhao Wei said's 'losses' refers to learning coins, because even if it is developed from the next generation of electric spindle technology, it is not necessarily to get thousands of learning coins.

According to past experience, it should be five hundred or eight hundred student coins. If there is a little loss, unless it is the electric spindle technology of the red breeze industry, it is possible to reach the international level, causing warm discussion of public opinion. Harvest more learning coins.

Of course, it is a learning currency 'loss', and it is definitely to be developed.

Zhao Wei still reluctantly used "derived rate", and immediately got the next generation of electric spindles, internal hollow body structural technology, know how to design a demompatient structure.

Obviously.

This is just a part of the spindle design and cannot bring learning coin rewards.

Zhao Qi looked at the empty, if they were also learning coins, with sighs, "I still have to count on the plane design, and I don't know if the aviation group, what happens to complete design acceptance work!"

"Their work efficiency is too slow!"

"It is already nearly two weeks, and there is no news!"
