The military-industrial scientific research system of the academic master.

What he just thought about was actually very simple.

It is to find a way to get them to agree to produce some important parts of "non-important models" in China while the aircraft manufacturers are focusing their main efforts elsewhere.

Main frame, landing gear, wings and even fan blades.

On the one hand, it can provide many high-end manufacturing jobs for the country. On the other hand, it can also allow more aircraft manufacturers to gain experience in manufacturing passenger aircraft parts in advance and train some skilled workers.

To be honest, Shanghai is not a suitable place for manufacturing.

Every inch of land costs too much.

Although Hufei generally cannot move around arbitrarily, once the production of domestically produced passenger aircraft increases, parts production will definitely have to be allocated to other factories under the aviation industry.

The ARJ21 and C919 on the original timeline adopted this form, with scattered production in various places, and finally completed assembly and testing in Shanghai.

In this life, the localization rate of domestically produced large aircraft will definitely be higher than in the previous life, and the number of companies and factories involved in the entire industry chain will also be greater.

Just one Figure 214, which has a high probability of not having a very high output, will definitely not be able to feed so many factories.

So the earlier you prepare for this, the better.

If it can succeed, then units such as Factory 112, Factory 132, Factory 410, Factory 172, and even the cities where they are located will benefit from it.

However, Chang Haonan is not the kind of person who likes to open champagne at halftime, so he still chatted with the other party calmly on the surface.

"You know a lot about this."

The aviation manufacturing industry and the air transportation industry can be considered to be two fields that have almost nothing to do with each other. Although Zhong Shihong is the director of the technical department of Factory 410, the things he mentioned earlier about civil aviation obviously did not come from his usual work. .

"Of course, I've loved airplanes since I was a kid."

When Zhong Shihong said this, his face was filled with memories of his childhood:

"When I was in elementary school, I watched a movie about air combat with adults."

"Because of my poor health, I knew I would definitely not be able to be a pilot, so I always regarded this as a hobby. Later, when an opportunity arose, I applied for transfer from Factory 103, which was engaged in mechanical equipment, to Factory 410."

A story similar to that of Chang Haonan, who chose to build airplanes because he couldn't fly them.

"But when you work in Factory 410, you rarely see a complete aircraft, right?"

the former asked with a smile.

"Indeed, most of the time I am immersed in the workshop, dealing with aviation engine parts." Zhong Shihong stroked his hair:

"But another reason why I chose to transfer here is that there are more civil aviation aircraft here in Shengjing. I have saved some money over the years, bought a camera and often go to the airport to take pictures..."

……

As the two chatted, the plane quickly landed at Lianhai Airport.

However, transportation and communication in this era were not smooth. It was not until that afternoon that the group finally met Professor Zhou Zexuan, the director of the Analysis and Testing Center of Lianhai University of Science and Technology, after looking in several wrong places.

"Thank you for your hard work on the road."

Professor Zhou took the two turbine blades and looked at them over and over:

"We need to perform metallographic examination on the inside of these... uh, small holes, right? What magnification is required?"

"It is best to measure both inside and around the hole. First use 200x and 500x magnification to look at the overall appearance. If problems are found, then look at the specific details."

"No problem, this is quick."

Due to confidentiality issues, Zhou Zexuan did not ask students to help. Instead, he put on gloves himself, wiped the surface to be tested with alcohol, and then immersed the sample in the reagent.

While waiting for the chemical erosion, Chang Haonan asked something that he had been curious about on the road:

"Speaking of which, Professor Zhou, since foreign manufacturers prohibit you from moving the position of the instrument, they probably want to restrict the specific use of the equipment. If you directly test it for us, won't there be any risks?"

Zhou Zexuan laughed directly when he heard this question:

"Restrict the specific use of personal P. After the equipment is purchased, unless they send someone to watch here at all times, there is no way they can know what we are doing with it."

"The reason for writing this kind of clause is, firstly, to make us feel disgusted. Secondly, and most importantly, we are worried that users will go to third-party manufacturers to buy wearing parts and perform repairs, which will cause their profits to be damaged."

"Some parts have no technical content at all and cost a few yuan at most. The Gringo Lion's Big Opening costs several thousand dollars each. If you dare not use theirs, they will refuse to provide you with after-sales service."

"If you can buy domestically produced equipment that you can use, who the hell would be willing to suffer this kind of anger..."

Chang Haonan understood immediately.

"I see……"

It is similar to the sanctions imposed on certain institutions and schools in China in previous lives.

For example, you are prohibited from using certain software.

Everyone knows that this will not have any real impact - the original ones are all pirated.

But just doing this gesture makes you feel sick by the way.

To be honest, it is the high-priced accessories and services that cause greater losses.

Before his rebirth, he had also heard that many faults of imported equipment were actually not difficult to repair, but the contract required that the original factory engineers had to deal with it. The price was extremely high, and the efficiency was extremely low. Work often had to be stopped for half a minute because of trivial matters. months or even longer.

Everyone chatted about other topics, and soon the chemical erosion process was over.

As the director of the analysis and testing center, Zhou Zexuan's work efficiency is unparalleled, and the optical inspection results were obtained in a short time.

Several black and white photos printed on paper.

Zhong Shihong was the first to come over, followed by the others who were traveling with him, and they quickly surrounded Zhou Zexuan.

"Um……"

The latter pondered for a moment and finally gave his judgment:

"The material around the hole has a uniform shape, and no cracks are found. Only a very weak uneven surface can be seen under 500 times magnification, which should be left by post-processing processes such as polishing."

Zhong Shihong next to him was obviously in a good mood after hearing this comment.

But before he could be happy for a few seconds, the next words made his heart suddenly lift:

"As for the inner wall of the small hole... the light is not very bright, but at 200 times magnification, some white strips or blocks can be seen."

"The shape of the inner wall of the small hole that has not been chemically corroded is similar. It has strong corrosion resistance..."

Zhou Zexuan put down the two pieces of paper in his hands when he said this:

"I speculate that there should be a remelted layer structure that has not been cleaned, but the specific situation, especially the thickness of the remelted layer, cannot be seen. If you are willing to pay additional testing fees, you can use a 2500x electron microscope for further testing! "
