The difficulties encountered by the Jian-20 project are not difficult to say, but they are not simple.

At the end of the day, it's just one sentence: it's too slow.

But to put it bluntly, there are many links involved.

The first is that the infrastructure can't keep up.

At present, the domestic infrastructure construction is insufficient, especially in the field of fourth-generation machines that require high-precision machine tools, advanced welding and smelting equipment, most of the resources have been sucked up by the No. 22 project, and the tentacles of 601 have even reached Bashu, taking away part of the production capacity of local enterprise suppliers.

As a result, the production capacity that 611 can obtain is quite limited, and can only meet basic needs.

If you want to rely on money, you can't smash it, after all, equipment can't be built in a day.

The second point is that the researchers are inexperienced, and after updating the design direction, the steering is relatively slow, and the progress is naturally slow.

They do need a senior leader to lead the turn, but Yang Wei, as the chief engineer of the project, cannot play such a role.

The third point is external pressure.

The J-20 project can be said to be the project facing the heaviest external penetration pressure in modern times, especially after the No. 22 project quietly released a big bomb, the outside world has accelerated the pace, wanting to obtain information about the J-20 project and make an obstacle from it.

Whether it is a personnel review or an update of the confidentiality system, it consumes a lot of time and resources.

The combination of these problems has led to the progress of the J-20 project far from meeting expectations.

So, in order to find a solution, Yang Wei thought of Chen Nian.

He knows Chen Nian's style, and what stands out is a simple and rude.

Whatever the problem, it is not a problem in the face of rapid technical iteration.

When the speed of development and application is fast enough, and the information is complete enough, in many cases, most of the problems can be solved.

That's a good idea, though.

Chen Nian hesitated a little, and after thinking for a moment, he asked:

"What do they want me to solve? I mean, the technical kind, told you? ”

"Having said that, the main problem is the engine deflection nozzle, the lift fan, and the transmission gear."

"What? Are they going to go to the STOVL system? ”

Hearing this, Chen Nian was shocked.

Although he has long known that the J-20 will transform into a carrier-based aircraft and is also pursuing short-range take-off performance, he has been busy with the high-speed rail and the Deep Blue 16 project recently, and has not paid much attention to the progress of the J-20 project.

How did it take only a few months for the project to directly cross over to the stage of vertical take-off?

You must know that the most typical representative of the so-called STOVL system is the F-35, if the J-20 wants to engage in the STOVL system, wouldn't it mean

The two advanced fighter projects of the United States have all been cut off by us? ——

Don't say it, it's kind of exciting to think about.

Regardless of the cost-effectiveness of vertical take-off at this stage, at least, this step of exploration is indeed necessary.

According to the strategy of Huaxia production generation, R&D generation, and pre-research generation, it seems that this is really the case with STOVL now

After all, after Deep Blue 16, the Chinese Navy will usher in the era of dumplings, there will be more and more offshore platforms, and if the J-20 can achieve STOVL, the combat effectiveness of the aircraft carrier battle group within the first island chain can almost be said to be invincible.

So, strategically, the 611 Institute's decision is not radical.

But to support such an aggressive strategy, the need for technology is enormous.

No wonder Yang Wei would want to let himself go over to help

Looking at Chen Nian's surprised expression, Chen Guo nodded slightly and replied:

"Yes, this strategy has been approved by the superior and matches the progress of the Deep Blue 16 project."

"According to the plan, there will be three models of J-20A, J-20B, and J-20C."

"A is a conventional model, B is a short take-off and vertical take-off model, and C is a carrier-based model."

"Among them, the Type A is progressing smoothly, there is a technical basis for Project No. 22, and there are basically no difficulties."

"The C-type is relatively complex, but with the blessing of the F119 engine, it is not too difficult to do."

"The most difficult thing to do at the moment is Type B"

Hearing Chen Guo's words, Chen Nian couldn't help but hold his forehead.

Rabbit, you still say that you don't know martial arts?!

Good guys, even the model division of the F-35 has been copied, what else can you not copy?

If this thing really comes out, what do you want the neighbors on the other side of the sea to think? Where do you put Loma's face?

"I know, I'll pack up and fly to Chengdu."

"However, I am not necessarily sure whether the problem can be solved, so I can only say that I will go and see."

Chen Nian is not humble when he says this, in fact, the previous analysis of the F-22 did not involve the design of vertical take-off and landing, and he is unwilling to waste additional source points.

Therefore, all he can rely on is the results of his learning during this period of time, as well as some literature about the F-35 that he has read in his previous life.

If there is any help to the problem, it must be.

It's hard to say how much it will help.

"Understand, you go and take a look, if it doesn't work, come back, or focus on your studies."

"Or you don't have to go, just ask them to send the document, and you can just read the document."

Chen Nian frowned and replied:

"You have to go, things on paper are often not as intuitive as in reality, and only when you are on the scene can you be inspired."

In fact, the core design of the F-35B is the two-pole counter-rotating lift fan behind the cockpit, the design principle of this thing is not complicated, but if you really want to get on the machine, you have to consider the matching of various systems and modules, if you are not on the scene, Chen Nian will not be able to recall those designs and parameters anyway.

"Okay, you choose the right time, and I'll arrange the itinerary for you."

"By the way, if there is any special event in the near future, it is best to let me know in advance."

"You also know the reason, some forces have been more active recently, and they are staring at us very much, and I will bring you unnecessary trouble."

"Got it."

Chen Nian nodded in agreement, and then left Chen Guo's office.

Walking out the door and looking at the blue sky, he suddenly had a feeling of unreality.

Are we going to engage in J-20B? Actually want to engage in vertical take-off and landing fighters?

Although it is only a pre-research and there is no plan to actually ship it in the short term, this matter is still of great significance.

Contrary to what most people think, this thing is not a "must" among Air Force aircraft, and there are many cheaper and more stable alternatives to it.

The meaning of the existence of the vertical take-off and landing fighter is to compete for the faint and weak opportunity to widen the difference in victory in the war.

It can be said that it is useless in the downwind game, and it is useless in the upwind game.

But if there is a war in which the two sides are in a state of anxiety of confrontation at sea, then its significance can be reflected.

The more planes that take to the skies in a short period of time, the greater the chance of winning.

This is an unquestionable iron law in modern naval warfare.

Therefore, from the actions of the 611 Institute, Chen Nian vaguely felt that something had changed.

On the "surface of the sea", the official attitude has become more radical.

From the Navy 16, to the J-20B, they all seem to be making some kind of preparation.

Perhaps, what was not completed in the era that I traveled back in time will be completed here ahead of schedule

Chen Nian shook his head, put away his chaotic thoughts, and returned to his residence in an inconspicuous special car dressed as a taxi.

Although he said that he was going to Chengdu, he did not have to leave immediately.

He had to sort out his schedule and get his class schedule right

At this time, in the 611 Institute, Yang Wei had just received a call from Chen Guo.

"He agreed? Good! Just agree! ”

"I'm just waiting for him to come, don't worry, I'll definitely give you security in place."

"Life problems? You don't have to worry about life problems, even if I drink rice soup and eat gruel, I will arrange lobster and abalone for him! ”

"What was the standard in Dongqi before, but it will be doubled by me!"

"Understand, I'll arrange it"

"There is no hurry in time, he shall prevail, we will wait at any time!"

Hanging up the phone, Yang Wei couldn't help but laugh out loud.

I've finally invited this great god over!

Although he had already invited Chen Nian to be the technical consultant of the J-20 project, since the re-planning of the project, Chen Nian has not invested much energy, but most of the time has been spent on the dark blue 16.

Finally, when he finished solving the problem of AGT110, Yang Wei thought that it should be his turn, but he didn't expect another high-speed rail project.

Seeing the results of the high-speed rail project, Yang Wei was red-eyed.

He couldn't wait that one day when the Spark Working Group was in a meeting, he would go directly up to grab Chen Nian and turn him directly to Chengdu, but unfortunately, this kind of idea can only be thought about.

Well, now that the other projects have come full circle, it's finally my turn.

Although according to Chen Guo's relay on the phone, Chen Nian was very conservative about this technical assistance, but Yang Wei was not disappointed at all.

Wasn't he just as conservative when he was doing exterior design?

What now?

The J-20A is about to make its first flight!

This young man always works miracles, and all he has to do is give him a chance.

Thinking of this, Yang Wei picked up the phone again, and after connecting the logistics department, he explained the follow-up arrangements.

Of course, he did not reveal Chen Nian's identity, only said that there were important leaders visiting and preparing according to the highest standards.

The intelligence service, for its part, has also stepped up security measures in the near future in accordance with his request.

Everything is ready, just wait for Chen Nianfei to come.

was busy until more than eight o'clock in the evening, and Yang Wei finished arranging all the work.

At this moment, he deeply felt that it was not easy for those people in the so-called "agency office" to do things.

In the past, as a technical leader, he never cared about this kind of thing, as long as you are not doing the right thing, no one will give face.

Because of this character, he almost couldn't even get along at home and went overseas.

But now, he suddenly understood.

The reason why there is so much red tape, in fact, to put it bluntly, is still one word:

Set store by.

Why do you care?

Benefit.

He values Chen Nian, so he tries his best to give him the best experience.

And the reason why I value him is because I know how much benefit Chen Nian can bring to this project, this institute, and even this country.

Thinking of this, he sighed.

If one day, everyone can realize where the "real interests" are, then the country can be considered completely hopeful.

Those who value Chen Nian should not be the only one.

Chen Nian should not be the only one who is valued.

Yang Wei shook his head, and subconsciously touched the phone, that is, this touch, he suddenly remembered an important thing:

I was so busy that I forgot about the main master!

He hurriedly dialed Chen Nian's phone and said softly:

"Hey, Xiao Nian, my Uncle Yang."

"When are you coming?"

"Oh, oh, don't worry, don't worry, arrange your own affairs first, I can wait here"
