The same was true for the others, surrounded them one after another, looking at the turbine blades with a little excited about Liu Hui.

Turbine blades!

Among the entire gas turbine, they are truly critical and important parts, and of course, it is also very difficult to manufacture them.

Liu Hui stretched out his hand, and didn't care about the dirty thing. He touched it, as if he was touching a peerless treasure. After touching it with a love affair, he ordered loudly: "Arrang to dismantle immediately and clean it as soon as possible."

"Okay, I'll arrange it right away."

Next to it is the director of the assembly workshop of the gas turbine branch. The lm2500 gas turbine is responsible for dismantling, cleaning, storage and other work.

Under the arrangement of the workshop director, two experienced fitters immediately came and started dismantling the turbine blades with hammers and copper rods.

First, one end of the copper rod was pressed against the lock plate of the turbine blade, and then tapped the other end of the copper rod with a hammer, and the lock plate was quickly knocked open.

The first lock piece, the second lock piece...

Everything went very smoothly, the locks of the entire plate of blades were knocked open, and then the first turbine blade was taken off in everyone's eyes.

“The first blade!”

"I just didn't feel angry, afraid of something wrong!"

“……”

Seeing the first turbine blade being taken off the turbine disc, the originally quiet scene immediately boiled, and almost everyone seemed very excited.

"Show me."

Regardless of the various dirty things on the leaves, Liu Hui took the leaf, looked at it carefully, and nodded gently.

Although the Americans stopped supplying our LM2500 gas turbine, Liu Hui was very dissatisfied with them, but he had to say that their technology was much ahead of us. It can be seen from the turbine blades. It is dirty, but it can still be seen that the craftsmanship is exquisite and represents an extremely high industrial level.

"After all the blades are removed, clean them immediately, and relevant technicians will intervene immediately to survey and map the turbine blades and get out the design drawings as soon as possible."

Several designers looked at each other next to him!

One person asked tentatively: "Mr. Liu, you don't want to survey and map and imitate the turbine blades of the lm2500 gas turbine!"

If this is the case, it's so scary!

Everyone is engaged in technology and knows the huge difficulty of this. It does not mean that you can imitate it just by having the actual blades. It involves many complex technical issues such as materials and technology.

Take materials as an example. It is estimated that there is no such high-temperature alloy material in China. If there is no material, there is also a copy of yarn. Could it be that I want to use other high-temperature aggregate materials instead?

Replacement is absolutely impossible. The material grade is incorrect, there are matching problems, and there are also service life problems, as well as a series of various problems.

Knowing the difficulty, this technician asked this question.

Liu Hui nodded and admitted: "I do want to imitate the turbine blades, and I also know that the technology is extremely difficult. No matter what, we first survey the drawings, and then think of solutions step by step."

It turns out that I really want to survey and map and imitate the turbine blades.

Many people looked at Liu Hui with admiration and thought to themselves, Mr. Liu is really courageous and dares to think and do it!

Gradually, these designers were also full of motivation.

Is it OK? Try it first!

If it could imitate the turbine blades, it would be a very exciting thing.

The lm2500 gas turbine has a service life and needs to be overhauled every 15,000 hours of work. Each overhaul means that many parts need to be replaced.

Some of these replaced parts are replaced after long-term use, such as wear, ablation and other defects.

A large number of parts have only one overhaul life, and each overhaul is replaced. These parts are required to be replaced.

Turbine blades are parts with service life. They must be replaced even if there is no quality problem. Also, if there is any problem with the blade during overhaul, they must be replaced even if they have not reached their service life.

This means preparing a large number of turbine blades for backup, but let’s not talk about important and critical parts such as turbine blades, even other simple parts.

The Americans not only stopped supplying, but also provided spare parts, and ignored the later repairs, which made our necks tightly.

Liu Hui wants to give it a try.

What if it succeeds?

If the turbine blades can be successfully imitated, it will solve a big problem. In the future, there is no need to worry about the gas turbine having no blades to replace.

Even if the technology is very difficult, Liu Hui wants to give it a try.

East China Sea Ship Design Institute.

Yang Fan is teaching everyone again, mainly explaining the modular design and versatility design of missile vertical launch system to the people in the weapon system design room.

According to Yang Fan's design ideas, every 8 vertical launch cylinders is a module, which can be combined as needed on the warship, either 6x8 combination or 8x8 combinations.

In terms of versatility, a variety of missiles can be launched, not only the current existing missiles, but also the newly developed new missiles can be launched through the missile vertical launch system in the future.

Dozens of people were so fascinated by hearing it!

Even Zhou Ping, director of the Weapon System Design Office, was no exception. He thought in his heart that he was worthy of Comrade Yang Fan and his speech was really wonderful.

On the blackboard in front, not only is the design simple drawn, but there is also a lot of text, which is simply full of pictures and texts. Yang Fan has been talking about it for nearly two hours.

"Okay, that's all for today's class. I hope it will be helpful to everyone's future design work. Below is the time to ask questions. If you have any questions, you can ask me now."

A designer immediately stood up and asked a question.

Everyone is very familiar with Yang Fan and knows that General Manager Yang has no airs. No matter what the design is, as long as they ask, General Manager Yang will answer and be very patient.

This questioning takes about half an hour.

He raised his hand and looked at the time. He felt that it was almost done. Yang Fan said loudly: "I'll be here today. We will have such classes from time to time in the future. Director Zhou Ping will be responsible for notifying you."

Warm applause rang out.

In this way, everyone thanked Yang Fan for bringing such a wonderful lecture. They waved their hands to everyone and walked out of the training room quickly.

Entering your office, sitting down and taking a pleasant sip of tea, taking a short rest, and then starting to review the design drawings sent over.

As the design of the missile vertical launch system gradually unfolds and deepens, it has now entered the stage of comprehensive and detailed design, and more and more design drawings have been completed.

After reading the dozen design drawings sent over, Yang Fan smiled happily. It was already lunch time and was about to go to Wangjiang Tower for dinner today.

At this time, Yang Fang should have booked a private room and was waiting for Yang Fan to come over. She just came back from Deep Sea City yesterday and had a very important matter to discuss with Yang Fan.

After sorting out his desk, Yang Fan left his office.

I got on my own big off-road car in front of the office building, drove out of the Donghai Inn and headed to the Wangjiang Tower Restaurant. The distance was a little far, and it took me more than 40 minutes.

At the entrance of the restaurant, there was a Mercedes-Benz sedan parked. Yang Fan almost didn't have to look at the license plate to know that it was his sister's new car.

Hongtai Supermarket is getting bigger and bigger. There are more than a dozen large supermarkets in Donghai City alone. Then, with Donghai City as the center, many surrounding cities have also opened branches. The number of these branches has exceeded the total of Donghai Supermarkets, reaching more than twenty.

The development of Deep Sea City is very fast, and there are currently nearly ten supermarkets. Yang Fang is already considering developing towards surrounding cities with Deep Sea City as the center.

With the deepening of reform and opening up, policies have become more and more relaxed, especially the window of reform, the city of Deep Sea City, Hongtai Supermarket has developed more and more smoothly there and has been completely on the right track.

Now, Yang Fang's vision is higher, and the threshold for opening a supermarket is much higher. The location is not very ideal. If the store area is not large enough, she will not open a store easily.

Every newly opened supermarket is a supermarket with good location and large scale.

In addition to opening a supermarket, Yang Fang had new ideas. After returning from Shenhai City, she wanted to discuss it with Yang Fan.

After parking the car, Yang Fan looked at his sister's new car, smiled with satisfaction, and walked into Wangjianglou Restaurant.

The second update is given.

I am very sorry, periarthritis of the shoulder seems to be getting worse and worse. I can only write so much. Don’t worry, as long as I have a little bit, I will work hard to update and strive to write more words.
Chapter completed!
