Start with the aviation industry

Chapter 317 Mr. Lin, I finally understand what you mean
"Boss is here!"

Someone reminded me, everyone looked over one after another, and saw Osman leading the way, followed by several people, walking towards here.

Behind him are some technical directors of Rolls-Royce, and everyone came here specially.

For a long time, the single crystal superalloy turbine blades used in several models have no major problems, but there are many minor problems.

They came here specially, just to take a look at the dismantled single crystal superalloy turbine blades, because there are many engines returned to the factory for overhaul in the past few days, whether they are civilian or military.

"Boss!"

"Boss, hello!"

The workers and technicians at the scene greeted Osman one after another, but he didn't respond one by one, but just nodded.

"How about the turbine blades on this engine?"

A technical director next to him immediately replied, "There are still a few fans that are ablated."

Hearing this, Osman picked up one of the blades and looked at it. He knew that this problem was not caused by the design of the engine, but by the quality of the batch of single crystal superalloy turbine blades.

The corrosion resistance and high temperature resistance of the blade itself are not enough and need to be improved.

"You all take a look!"

The technical directors next to each picked up a turbine blade and looked at it in their hands. No one spoke, only a dignified face.

Osmond said, "Everyone, how do you think this problem should be dealt with?"

The scene was silent for a while, and then someone tentatively replied, "BOSS, I think it is necessary to carry out technical research to improve the performance of our single crystal superalloy turbine blades, make it more corrosion-resistant and stronger, use it Manufactured turbine blades last longer."

Someone immediately objected, "It is too difficult to carry out technical research, and the cycle will be very long. We have to invest a lot of manpower and material resources, and we cannot solve the current problems at all for the time being."

"Yeah, I don't know when it happened, it's too far away."

"."

They saw the situation of these turbine blades on the spot and talked about it, but there was no good way for the time being. It seemed that there was no second way except to tackle key problems.

Some people even proposed to reduce the overhaul cycle of the engine, the original [-] hours will be reduced to [-] hours, or [-] hours, and the original [-] hours will be reduced to [-], or [-] hours.

This is of course a bad idea!

Reducing the overhaul cycle means reducing the overall life of the engine, and the loss is very large, so Osmond vetoed it on the spot.

a few days later.

Osmond was looking at a summary report in the office, which was the inspection status of the single-crystal turbine blades of dozens of overhauled engines recently. They had more or less problems, such as ablation problems, and even a small number of non-destructive inspections of the blades Microcracks were found.

After reading the report, Osmond frowned.

He was even thinking about whether to replace these single-crystal turbine blades with titanium-aluminum alloys, but he quickly denied it himself.

Turbine blades are key parts. Changing the material grade requires a lot of verification and test runs. It cannot be completed at once. It will take at least half a year or even more than a year of verification time. Only after full verification and no problems can it be done.

In addition, the working environment temperature of high-pressure turbine blades is the highest, and titanium-aluminum alloys cannot adapt to such high temperatures, so single-crystal superalloys can only be used.

After frowning and thinking for a long time, Osmond said helplessly, can it really only be spent a lot of manpower and material resources on technical research?

But he knows that the investment in this area will not be a small amount. In addition, he is not fully sure that it will be successful. It may take three to five years, or it may take more than ten years.

As for other aviation industry enterprises, how about the quality of their single crystal superalloy turbine blades, will such problems also arise?

After thinking about it, he picked up the phone on his desk and called some of his colleagues. Although others may not tell the truth, it is useful to know a little information.

After making two phone calls, he learned very little. After thinking about it, he called Lin Feng.Osmond thinks that the relationship with Lin Feng is not bad, and Rolls-Royce and Leihuo Technology Industrial Group are also in a cooperative relationship, and maybe they can get some things he needs.

"Boss Lin, I'm Osmond."

"Hello, Mr. Osmond." Lin Feng's voice came clearly from the microphone, "What's the matter?"

This is an international long-distance call. To make a long story short, it is better to get straight to the point. Lin Feng didn't mean to be polite, and asked directly what the matter was.

Osmond said, "Mr. Lin, the high-pressure turbine blades of the LH165 turbofan engine that your company is developing should use single crystal superalloys."

He had been to Leihuo Technology Industry Group two or three months ago, and learned that Leihuo Technology Industry Group was designing and developing a military turbofan engine with relatively advanced performance. He guessed that this turbofan engine should use single crystal high-temperature alloy blades.

Lin Feng did not hide anything, and was secretly happy in his heart. After waiting for two or three months, Osmond finally called and asked about the single crystal superalloy.

"Mr. Osmond, our engine does use a single crystal superalloy turbine blade, and I also gave you a piece of such a single crystal superalloy."

Suddenly, Osmond remembered.

Two or three months ago, Lin Feng once gave him a gift, which seemed to be a piece of single crystal superalloy, but he couldn't remember where to put it for a while. If Lin Feng didn't mention this matter, he probably forgot about this piece. presence of superalloys.

"Mr. Lin, you gave me such a high-temperature alloy, there should be some deep meaning." Osmond finally thought so. Before, he always believed that the single-crystal superalloy of Rolls-Royce was the best in quality and performance in the world. .

Lin Feng said, "If it is said that our company has mastered the directional solidification technology of the world's best single crystal superalloy, you may not believe it. You should take this single crystal superalloy for some tests first."

After chatting on the phone for a few words, Osmond began to search for that piece of single crystal superalloy all over the world. He searched all over the office, but he couldn't find it.

Where is it!

Terrified! ! !

Osmond turned around in a hurry, patting his head from time to time. At this moment, he regretted a little. Why did Mr. Lin just throw away the things that Mr. Lin specially gave him, and didn't take it seriously at all. Now he doesn't even know where to put it up.

After sitting there for a long time, racking his brains, Osmond finally vaguely remembered that the piece of metal seemed to be in his study.

So what are you waiting for, go home right away.

Osmond hurriedly prepared to go out. His assistant was taken aback when he saw this, and then immediately reminded, "Boss, you have an important meeting in 10 minutes, and you must chair it."

Osmond didn't turn his head back, and walked out in a hurry, shaking his head and saying, "The meeting is cancelled, and now I have something very urgent and need to go out immediately."

A Rolls-Royce quickly left the headquarters of Rolls-Royce. It was so fast along the way that many cars voluntarily avoided it. It would have taken about 10 minutes, but Osmond only took [-] minutes this time. At the door of his big villa.

He slammed on the brakes, then got out of the car quickly, trotted all the way into the big villa, opened the door and entered his study room, searched hastily, and finally let out a long sigh of relief.

Something was finally found.

Together with the gift box, this piece of single-crystal high-temperature alloy was placed in the drawer of his big desk intact. He took the alloy to look at it, and then, Osmond hurried out of the big villa with it. I hurried back to the company.

The next thing was simple. He called a technical director with one phone call, and then gave instructions to conduct a comprehensive performance inspection of this single crystal superalloy at the fastest speed, and form an inspection report as soon as possible.

afternoon.

A more detailed inspection report was finally released, and the technical director knocked on the door and delivered it in person, "Boss, the single crystal superalloy has been inspected, and this is the inspection report."

It can be heard that there is a slight excitement in his tone.

But Osmond didn't notice this. He just wanted to have a look at the test results, and immediately flipped through the test report after receiving it. Gradually, the expression on his face became brighter.

This, this, this.
This is not scientific! ! !
After being stunned, Osmond immediately realized that he was a vice president after all, and he had seen all kinds of big scenes, so he asked with a straight face, "Are your data correct?"

If you listen carefully, you can still hear the fluctuations in the tone. In fact, Osmond is excited in his heart, but he doesn't show it on his face.

Because the data in this report is so perfect, whether it is high temperature resistance, corrosion resistance, tensile strength, yield, etc., it is completely ahead of their current single crystal superalloys, which is directly a grade higher.

No wonder his first reaction was to ask if the data was correct.

Of course, the technical director knew what Osmond meant, and replied in a slightly excited tone, "Boss, we thought the data was wrong at the beginning, so we checked it again, only to find that the data was all wrong. All correct."

"It's really correct!"

"It's all true, I can guarantee that!"

Hearing such an affirmative answer, Osmond finally couldn't hold back a little bit, showing a look of surprise, such a single crystal superalloy was exactly what they needed.

With such an excellent single crystal superalloy, he is sure to improve the performance and quality of turbine blades in an all-round way, including the service life.

No wonder, no wonder Mr. Lin gave me such a piece of single crystal superalloy!
Now, he completely understands!

He pressed the call button on his desk, called his assistant over, and ordered, "Book a ticket to Huaxia immediately, and I'm going to Leihuo Technology Industry Group again."

The assistant was stunned. The boss had just been to Leihuo Technology Industrial Group two or three months ago, so why did he go again, and he was so eager.

Although he couldn't figure it out, he still nodded and said, "Okay, I'll book the ticket and arrange the travel right away."

Leihuo Technology Industry Group.

On a large table, lay out a design drawing. Lin Feng was looking at it seriously, and holding a pencil, he would mark out all the places that needed to be revised, and some places would even be corrected with a pencil.

This is the blueprint for a stealth strategic bomber.

The design of this aircraft is progressing very smoothly, and now it is entering the finishing stage. Sometimes Lin Feng goes to Leihuo Aircraft Design Center, but most of the time it is there that he sends the design drawings.

All design drawings that are slightly more important and critical will be sent over according to Lin Feng's request, and Lin Feng will personally check them.

"Boom, boom, boom!"

There was a knock on the door, and Ding Haixia walked in with a fax she had just received, and reported, "Boss, I just received a fax from Rolls-Royce. Vice President Osmond and his team of five will come to visit our group." .”

Lin Feng put down the pencil in his hand and smiled happily. He fully knew the real purpose of Osmond's coming here. It must be to inspect the single crystal superalloy, and then came to discuss cooperation matters.

"Boss, how do we reply."

"Welcome to them."

Ding Haixia turned and left, and went to send a reply fax.

Lin Feng smiled again, Osmond's speed is so fast, it seems that they are in urgent need of such a single crystal superalloy.

Lin Feng couldn't be more clear about his single crystal superalloy. It is definitely much better than the single crystal superalloy of any aviation company in the world. Moreover, looking at the whole world, there are already enterprises capable of producing single crystal superalloy. There are only a few.

After thinking about this matter, Lin Feng calmed down again, and carefully read these design drawings, one after another, trying to make each design drawing as similar as possible to the design drawings provided by the system in his mind.

Two days later, Osmond and his party arrived at Leihuo Technology Industrial Group.

After exchanging polite greetings, Osmond apologized, "Boss Lin, I'm really sorry, I didn't understand what you meant for a while, and I didn't realize it until you reminded me."

Lin Feng smiled, "How about the performance of our single crystal superalloy?"

Osmond was completely stingy with words of praise, exaggerating this single crystal superalloy to the sky, and he did not hide his envy in his words.

"Mr. Lin, this is exactly the single crystal superalloy we dream of. How about we talk about cooperation?"

Lin Feng said, "Yes, no problem."

Hearing this, Osmond was overjoyed. He seemed to see hope at once, and he directly expressed his thoughts, "Mr. Lin, we want to buy this directional solidification technology of single crystal superalloy. How much does it cost? Do you want to buy it?" One price."

It is worthy of being a well-known aviation industry enterprise, but it is not short of money!
However, Lin Feng shook his head and reminded, "Mr. Osmond, you have to know that this is the world's most advanced single crystal superalloy directional solidification technology, and we will not sell it."

what!
After working for a long time, you guys don't sell it!
Immediately, Osmond's face couldn't hide the disappointment. They really urgently need this kind of single crystal superalloy.

However, he soon saw a glimmer of hope.

Lin Feng said, "It is impossible to sell this technology, but we can still cooperate. You provide the design drawings or rough drawings of the turbine blades, and we will manufacture them according to the drawings."

Is this the way of cooperation?
Osmond pondered for a while, and finally made a decision after thinking about it, "It's okay, then cooperate in this way."

The two sides talked for a long time, negotiated all the details, and signed a formal cooperation agreement.As for the price of each turbine blade, there are three grades according to the accuracy and the complexity of the blade shape.

According to the weight of the blank, the settlement is respectively US$0.5/gram, US$0.6 and RMB0.8/gram.

Rolls-Royce provides the rough drawings of the blades, and Leihuo Technology Industry Group manufactures the blanks of single-crystal superalloy blades according to the drawings, and Rolls-Royce is responsible for the subsequent processing.

"Boss Lin, happy cooperation!"

"Happy cooperation!"

After the agreement was signed, the two happily shook hands.

Osmond is happy because they will have the world's top-level single crystal superalloy turbine blades. Lin Feng is happy because after forming such a cooperative relationship, Rolls-Royce's dependence on Leihuo Technology Industry Group has further strengthened.

With this agreement, Osmond and his party went back happily. It is estimated that the rough drawings of the first batch of turbine blades will be sent over in a short time. Then, Leihuo Technology Industry Group will make the blanks of the blades. Pay by weight.

According to the output value of Rolls-Royce, a lot of engines are manufactured every year, and there will be a lot of single crystal superalloy turbine blades needed. This cooperation should bring a lot of revenue to Leihuo Technology Industrial Group.

The absorbing material of this stealth strategic bomber was first produced in the non-metal material workshop of Thunderfire Helicopter.

From the start of production preparation to the first batch of products, it takes only two to three months. With a complete set of technical data, the whole process is not complicated, and the manufacturing cost is much lower than imagined.

The first batch of absorbing materials has been produced, and the next step is of course design verification to see if the absorption rate of radar waves can meet the design requirements.

How to verify it?
The most effective and direct way is to spray a certain aircraft with such a wave-absorbing coating, and then test it under the radar.

The Leihuo Technology Industry Group only has helicopters, which are obviously not suitable for such experiments. It must be a fighter jet or a bomber, preferably a bomber, because it is large and can better reflect the performance of this wave-absorbing coating.

Lin Feng knew that this kind of absorbing material was too good, and fighter jets were relatively smaller. After applying the absorbing coating, it might be impossible for radar to detect it. Let's try a bomber first.

It is not difficult to do such a test and verification, just go to Xie Kangquan directly, and he is probably very happy to help.

So, Lin Fengbo called Xie Kangquan.

Another [-] words have been updated, and I still ask readers for monthly ticket support!
