Black technology: I can decompose everything

Chapter 134 Coefficients
"It looks good, it's alright, old Liu, my ears are getting calluses from your nagging, to be honest, the shape of this plane is really nothing to say.

You know, when you first brought this plane over, I thought it was my eyesight, so let me know, have you dug back the designers of the old American Aifu? "

The staff in charge of the wind tunnel seemed very impatient with Lao Liu's question at first, but then they became gossipy and asked Lao Liu teasingly.

"Let's go, if we really get the designer of f22 back, we still need to launch the current single-engine aircraft. We don't want to directly develop heavy aircraft?

Don't talk about these things, what is the next step? "

Hearing Lao Liu talk about business, the staff at the wind tunnel also became serious.

"Speaking of which, as far as you provide the data blown out of the clay mold, the next step should be to blow the supersonic wind tunnel.

But blowing it with a clay mold is definitely not enough. The intensity cannot be achieved at all. Forcibly blowing with a clay mold has only one ending, that is, it will be blown away immediately when the wind speed is high!

You know the old Liu I mentioned very well, it is obviously redundant to ask my opinion! "

When Lao Liu was told, his face was also embarrassed. Didn't he know that the clay mold could not be used in the supersonic wind tunnel?Of course he knew, but he just wanted to change the subject, but even if he was directly talked about like this, he would still be embarrassed.

"That's fine, I'll go back with the clay model later, and after we get the scaled metal model out, I'll come over and continue blowing.

When I come back next time, I think I will be able to blow out the final data of the shape of this aircraft, so get ready to work overtime! "

After they finished speaking, they chatted about other things, and then Lao Liu checked the current state of the clay mold. After all, he had just come down from the wind tunnel, and even though they had reinforced the clay mold, he was still a clay mold.

Therefore, the main wing of the aircraft made of oil sludge inevitably had slight cracks. Although they were not large, there was still a problem with the strength.

When Lao Liu saw this, a cloud of haze flooded his heart. Although the shape and structure of the aircraft are not problematic at present, there are new requirements for the materials used to manufacture aircraft in the future. He just does not know the existing materials. Can you stand it.

But now is not the time to think about these things. The most important thing now is to blow out the wind tunnel data first. As for the problems that will be encountered in the material in the future, we can solve them later.

When no new aircraft is launched, it will be smooth sailing, so the problem encountered now is just a hurdle on the road to success.

Lao Liu took the clay model and the wind tunnel data that had just been blown out, and went directly back to Chengluoma, and it was time to apply for structural proofing when he went back.

To get a one-to-one prototype, let’s finish all the wind tunnel tests first. As for the internal structure, don’t worry about it now.

When Lao Liu returned to Chengluoma, Li Zhenhua was studying with Professor Du and Song Cong together around the design drawings.

As soon as Lao Liu came back, he came to them, holding the wind tunnel data he had just blown in his hands.

"Lao Song, Lao Du, I'm back. Oh, Xiao Li is here after the Chinese New Year?" Lao Liu and Du Sanyi Song Cong greeted each other, and saw Li Zhenhua pat him on the shoulder as well.

"All the data blown with clay molds are here. Based on the data obtained now, the lift coefficient is estimated to be between 1.6-1.85, which is better than our current No. [-] performance.

However, he didn't go to the hypersonic wind tunnel. After all, the clay model is still a clay model, and he can't replace the real machine at all.

So if you want to continue, the prototype for the blowing tunnel is essential, and I suggest that since we have reached this point, why don't we just do it in one step and make a one-to-one comparison.

I also have a general idea, we will transfer the materials of an aircraft from the No. [-] project, and directly make it according to the standards of the real aircraft. Even if we fail to meet our expectations in the end, I think the cost of a No. [-] Totally worth it. "

Old Liu said all his thoughts in one go, but the wind tunnel data he got back was in Song Cong's hands.

Song Cong was looking at the data in his hand at the moment, and Professor Du came over, his eyes also fixed on the data.

Li Zhenhua, who was listening to this, felt at peace when he heard the wind tunnel data, because he already knew the lift coefficient of the aircraft he created.

When the decomposition machine analyzed it, it was already clearly marked. The lift coefficient is 1.89, which will be less than 1.9, but even so, it is still higher than the f22 lift coefficient.

Song Cong on the side was silent for a while after reading the data before speaking.

"The lift coefficient of this aircraft is very good. The coefficient of our No. 1.8 is only 22, but unfortunately, it is still not as good as the 2.0 of the f[-] disclosed by Lao Mei!"

After speaking, as if he was afraid of hurting Li Zhenhua, he said to Li Zhenhua: "Zhenhua, your design is already great. Even if it is not as good as F22 now, I believe you will be able to do it in the future!"

But what they said, Li Zhenhua didn't take it to heart at all, because he came from later generations, he knew the coefficient of F22 well, and it was exposed that the coefficient of the data simulated by the wind tunnel did not reach 2.0 at all. Only 1.7.

After Song Cong finished speaking with Li Zhenhua, he returned to the question raised by Lao Liu.

"Old Liu, regarding what you said, I agree with the proposal of making a one-to-one shape prototype, but I have nothing to say about it, and it still needs to be discussed at the meeting before it can be settled.

And I think, now that we have the design drawings of the exterior and internal structure, it is better to just make a real prototype.

Your idea is only to deal with appearance, but I want to take your proposal one step further.

Directly use our No. [-] to fill the inside of the prototype, combine this shape with our No. [-], and make a real prototype. "

Hearing what Song Cong said, the three people around him all widened their eyes and looked at him in disbelief.

His idea is really bold and risky, which is equivalent to omitting many steps and directly entering the prototype production.

"Old Song, are you taking some risks?" Du Sanyi stood beside him and advised.

"It's okay, Lao Du, we can still bear this risk at Loma. In fact, to be honest, we are still under a lot of pressure at Loma.

Especially after Lao Mei's F22 progress was disclosed, our Air Force should not fall behind any longer. Coupled with what happened in Guanyinhai last year, our Air Force also needs fighters like F22.

Although what we are doing now is only a single-engine medium-sized machine, it still cannot catch up with the f22, which is a heavy-duty machine, but we can also fight back against it to a certain extent. "

After listening to Song Cong's words, several people understood what he was thinking, but there was still a sad expression on their faces.

"Oh, don't be like this. Actually, it's fine. It doesn't matter if it's successful or not. I'm just reporting my ideas. It doesn't matter if it can be the best or not. We just need to do it step by step!"

Hearing what he said, several people felt relieved a lot.

Song Cong then chatted with them a few more words, then left here, went directly to the leader of Cheng Luoma, and told his thoughts.

The next few days were very peaceful. As for Song Cong, since he reported his thoughts that day, he didn't mention these things again when he came back, he just said that he was waiting for the good news.

Until the fifteenth day of the first lunar month, Cheng Luoma's employees finally understood all the designs that Li Zhenhua took out.

When all of them were about to start incorporating some of the technologies on No. [-] into these designs, Song Cong finally got the latest instructions from the leaders above.

When Song Cong got the latest document, he fell into extreme ecstasy. The document said nothing but the topic that Song Cong had submitted to the above.

I finally got a reply today, and the reply still agrees to implement it, which means that they can really directly trial-produce the prototype.

Of course, Song Cong also had a clear positioning for them, and he didn't do it all at once, but made a small plan, that is, first, according to Li Zhenhua's drawings, he made out the shape of the aircraft and the internal structure.

As for the things inside the plane, such as landing gear, avionics system, radar, etc., they are all placed later. Make sure that the one-to-one prototype comes out first, go to the blowing hole first, and get the final data.

While conducting wind tunnel experiments on the aircraft, they combined No. [-] with the internal structure diagram of the aircraft, and solved any problems that occurred during the design process.

Try to fully develop the aircraft they have in the shortest possible time. It is best to be able to complete the production and manufacture of the aircraft before the old f22 enters service on a large scale, and make the first flight.

The current air force really needs a main fighter to be able to top it, especially after the Guanyinhai incident, otherwise Chengluoma would not be in a hurry to launch the No. [-] project at the beginning. Such an air superiority machine is on top.

Compared with multi-purpose fighters, air superiority aircraft still have a wider range of use. The role of air superiority aircraft is only to allow the Air Force to have usable aircraft, but it does not really allow the Air Force to have air superiority.

However, these design drawings after Li Zhenhua are completely different from the previous No. [-] in terms of attributes.

Although he was still born out of the No. [-] project, strictly speaking, these design drawings from Li Zhenhua's hands are no longer air superiority aircraft at all, but have been transformed into multi-purpose fighters.

If you want to say who he wants to compare this fighter with, it is undoubtedly the F35, which has no shadow yet.

Both are medium-sized fighters, the same stealth fighters, the same single-engine single-seat, and the same double vertical tails.

In order to allow the Air Force to bridge the gap in air power with Lao Mei and other countries as soon as possible, as long as there is a slight possibility, they will try.

Therefore, under these many factors, the design drawings that only exist on paper are about to enter the stage of trial production.

However, after everyone got the news, their emotions immediately became high. Even if they all spent the Chinese New Year working overtime, they are still in a state of blood.

After Song Cong got permission, all [-]% of the original No. [-] project was transferred out, leaving only [-]% to continue to complete the follow-up test flight of No. [-].

With the continuous addition of personnel, the progress of the combination of No. [-] Project and Li Zhenhua's design drawings is also steadily advancing.

Lao Liu, who was in charge of the blowing tunnel before, is now directly rooted in the workshop, and has been watching the workers all the time, taking the first step to figure out the appearance of the one-to-one machine.

He wants to know now, what is the final data blown by this plane, as long as it is really similar to the data calculated by blowing the clay mold before, then their step will prove that they have not made a mistake.

And after the personnel of No. [-] machine continued to join in, Li Zhenhua seemed like a fish in water. No matter what parts department he was in charge of, he would go over and get involved.

Sometimes I go to look at the avionics system of this era, browse the skin materials of the aircraft, see what style the landing gear of the aircraft uses, and what kind of craftsmanship the canopy is...

Anyway, after he kept wandering around, he also had an understanding of the technical level they were in now.

What is the extent of these things, and how far is it from the decomposition machine in his mind? Can you take the right opportunity to take out the things in his mind?

Time passed quietly like this, and during this period of time, he was truly integrated into the project, and because of his talents that he continued to show outwards, everyone gradually gained some voice in the crowd.

Especially in some places, Li Zhenhua's opinions can be really used in the end. For example, in terms of landing gear, he has also given the solution to the problem of kneeling landing gear that could not be solved before. .

Of course, he didn't take it out directly, although he already had a complete set of design plans in his mind.

Li Zhenhua puts forward his opinions first, and then gradually integrates them into people. After that, he gives solutions where people encounter difficulties inadvertently.

Although people finally solved the problem, there is still a gap with the plan in his mind, but this is enough, as long as there is the final effect to be achieved, there will always be a perfect state.

The days passed day by day while Li Zhenhua was so busy, and the difficulties in the project were discovered, solved and improved little by little.

Time often passes very fast when he is concentrating on doing something. Before he knew it, he had been in Chengluoma for more than a month, and now Beihang University has already started school.

But as a student, he didn't report back to the school, but with Du Sanyi, the school's affairs are not a problem at all.

On this day, after more than 20 days of rush work, Lao Liu finally made the shape one by one according to the design drawing!
