Chapter 295: Fighting for the Plane

"Mr. Zhou, Lao Mou, this way."

"Master Wen, just call me Xiao Zhou."

Zhou Rui was led to a small building outside Factory No. 03.

Today is already the third day in the 919 factory.

This is also Zhou Rui’s second visit to Factory 03.

The overall appearance of Factory No. 03 is a huge rectangle with a terrifying area. Walking in it, it feels like you are in a covered square.

There are also some "ear rooms" on both sides of the No. 03 factory. Some are warehouses, some are equipment rooms, and some are rest rooms. They can be seen as small squares connected to the main body of the factory.

The place Zhou Rui came to at this time was very special. There were heavily armed soldiers at the door, and there was no window in the whole house.

Only three words were written: reference room.

This is the place where the J-20 design drawings are stored, or one of them, specifically for factory technical workers to call and consult at any time.

The design drawings of the J-20 are very large and are divided into dozens of different links. The total volume is said to be hundreds of G, which is calculated in tons when converted into paper materials.

Most people can only check content related to themselves. For example, what Zhou Rui can see is the part related to the skin. Other weapon systems, cockpit systems, fuel systems, radar systems, etc. are not visible and require additional applications. .

And more than three people must be present at the same time, and no copies are allowed. If you need to borrow paper materials to use in the workshop, each piece of paper has a number and must be returned in its original form, and everyone in the team must bear the responsibility of supervision and confidentiality.

Zhou Rui looked at the small room that looked like a prison, with several computers that were not connected to the Internet, and the soldiers looking intently behind them.

"That's it?"

Wen Hongqi said with a smile: "The atmosphere is a bit strange. I will get used to it in two or three days in the next three days. This is how we check the design drawings."

Smiling like the warden

It was a little different from what Zhou Rui thought. His original plan was to use the "master time" to quickly understand the relevant design drawings of the J-20, and maybe he could get some other inspirations, but under observation, this was obviously not the case. realistic.

The content of the information was extremely large, and Zhou Rui was not a mechanical student, so he could only turn on the focus time.

From time to time, I have to discuss it with Wen Hongqi.

In the last five hours, the concentration time was full, and the "prison guard" behind the scenes changed three times before I had an overall concept.

There is no fine button, fine button will stay here today.

The so-called skinning literally means applying skin to the aircraft.

In the early days, the main purpose of the skin was to make the fighter aircraft stronger and more stable, have a relatively better aerodynamic shape, and there were even skin designs for bulletproof purposes.

But now, beyond visual range, supersonic speed, and super perception are the needs of the new generation of fighters. It is no longer the era of thick steel plates to protect against machine guns.

Whoever you hit will hit the target with one shot. The key is that you have to be able to hit it.

Smart skinning means that a large number of sensors are embedded in the skin during the skinning process, so that the "skin" of the aircraft has all-round external sensing like human skin.

Compared with the past, where sensors were concentrated in specific locations and each had its own business, smart skin is much more comprehensive.

As for its materials, at least the J-20 plan uses special flexible materials as carriers, allowing the aircraft to withstand greater aerodynamic loads and deformations.

For example, the natural deformation of materials during flight, as well as the increase in reflective surfaces caused by opening the weapon bay and changes in the canards.

The flexible material here is a high-elastic fiber membrane. This is the key point and will be examined later.

In the original design, the J-20 planned to add a ferrite invisible coating with a total thickness of about 2mm under the flexible material.

It is thicker than a one-yuan coin, equivalent to a layer of "putty", and it is also fragile putty.

This is a decision made after "referring" to the f117 and f22 technical paths from various channels.

Now that we have four images, it seems to be much easier, but there are also many problems.

First of all, the "four-image material" with electronic control properties needs to be combined with various sensors on the surface of the aircraft, and even part of the circuit system can be replaced with four-image metamaterials to reduce internal space pressure.

In addition, the splicing of four-image materials also requires high precision, otherwise it will affect the absorption rate and stability.

Finally, for the "four-image metamaterial" used in the J-20, the base material can no longer be scum like PET, but the flexible high-elastic fiber membrane developed by Rongfei, code-named MP3. (Skin material No. 3)

This part also requires some effort. While preparing new materials, we also need to teach the technical staff here.

Zhou Rui spent five hours painting design drawings, again in a closed space without windows. When he came out, he felt like he was released from prison, greedily sucking in the fresh air.

Five hours! You can watch any movie you want!

Mou Zhongyi couldn't hold on for a long time. He was old and lacked blood and energy. He became weak after just two hours of watching.

After Zhou Rui came out, he summoned all the "Furui" people and immediately organized work groups.

"We don't have many people, but we still need to divide the work. Ke Chunjiang and Pan Xiangling haven't arrived yet, and some of the remaining eight people have to prepare four-image metamaterials based on MP3 substrates."

As soon as these words came out, several gay men dodge and their eyes wandered.

There is such a "big guy" (fighter aircraft) sitting in the factory, and you ask them to go back and do the film

Making films is not as interesting as making airplanes.

Zhou Rui looked at everyone's expressions and knew what they were thinking, but someone still had to do the work.

Finally, he looked at Mou Zhongyi, Han Ziyin and Xue Li.

The three of them were relatively weak physically, so the work in the factory was not hard, but it was definitely not easy.

With Mou Zhongyi in charge, the progress there was guaranteed.

Mou Zhongyi struggled a little, but finally nodded and said, "Forget it, forget it. I'm really old. I can use my brain, but it's a bit messy to do it. I'll lead the team to prepare new materials."

Han Ziyin and Xue Li had no objection.

The task of the other five people was arduous.

If everything goes well, there will be results in two months. If luck is bad, it's not surprising that nothing can be done in two years.

Zhou Rui said: "We mainly provide guidance and assistance, but if you want to solve practical problems, you must have the ability to do it yourself and understand the process flow. Otherwise, you won't know what to say to others, and the discussion will be irrelevant."

"I have discussed this with Master Wen. In the first week, we will learn while doing, master some basic processes, not too strong but understand, and also explore the technical points of the new skinning process."

"You are all outstanding in the scientific research community. I believe you can do it. If you really can't do it, it doesn't matter. You can go to Mou Laoer's group to help prepare new materials."

Several big men shook their heads like rattles.

"It can be done! I was born to be a screwdriver! My nickname is Little Screw."

"The fortune teller said that I will become a technical expert in the future. I have been doing scientific research purely because I took a detour for more than ten years! Turn it over!"

"My right hand is fast and steady, and my left hand is smooth and coherent. Just watch me perform!"
