The Black Technology Chat Group of the Ten Thousand Realms

A few days later, in the reception room for foreign guests of Huaxia Commercial Aircraft Manufacturing Company, Anderson Fergus, a representative of Honeywell International in the United States, and Kelly Hall, a representative of Rolls-Royce in the United Kingdom, were negotiating and waiting.

Their goals are the same, both are to sell the manufacturing technical information of engine blade materials to Huaxia Commercial Aircraft Manufacturing Company as soon as possible. The two sides are competitors, and it is inevitable to test each other to find each other's bottom line.

"You two, I've made you wait for a long time." Peng Zhengge said from the door.

"Mr. Peng!" The two stood up and shook hands with him, eager to know the decision of Huaxia Commercial Aircraft Manufacturing Company.

Generally speaking, this kind of thing should be discussed separately, because no matter which side is rejected, it is more hurtful. But today Peng Zhengge is not worried about this problem, because he doesn't need to reject either party, the other party will naturally understand.

"Before discussing cooperation, I would like to invite the two of you to visit our Institute of Aeronautical Materials again. Today is the day when we test the latest low-pressure turbine engine blades, and I would like to invite the two of you to visit together." Peng Zhengge said.

"That's right, I'm also very interested," Anderson said.

"It's an honor." Kelly also expressed his interest.

On the way, Kelly Hall has also been emphasizing the importance of their blade material technology with Peng Zhengge.

"Now all the aero-engines that Rolls-Royce manufactures for Airbus use this new type of titanium-aluminum alloy blade. Its improved fuel efficiency has greatly enhanced the competitiveness of commercial aircraft. Airbus A350-800, A350- The 900, A350-1000 and the A350-900ULR in development will all use this blade material for aero engines.”

"And Airbus, relying on this fuel-efficient model, has won a large number of orders from around the world, competing with Boeing 787-9 and 777-200ER passenger aircraft for the market. If Huaxia Commercial Aircraft Manufacturing Company can use this new material, instead of Nickel-based alloy blade materials, the market competitiveness will definitely be more than doubled!"

"Mr. Hall is the same as we think, our idea is to apply this new material to aero engines as soon as possible. Therefore, the purchased aero engines also use this new material." Peng Zhengge said.

"Yes." Kelly Hall continued to sell and said: "If we can cooperate on the manufacture of this material, your company will no longer have to spend a lot of money on this material in the future, but can manufacture its own production. ."

He just finished speaking, and Anderson also said: "We Honeywell are also willing to carry out such cooperation."

"You two, let's talk about this after visiting the material testing of the Institute of Aeronautical Materials." Peng Zhengge said mysteriously.

When Anderson heard his tone, he had an inexplicable feeling, just like the large-scale molding technology of carbon fiber composite materials before. Did they tinker with it again this time?

impossible? If it is said that Hongxin Group has already developed carbon fiber composite materials for the manufacture of other high-tech equipment, but this time the materials are only used on aircraft engine blades! It is unlikely that the R\u0026D technology will be available in advance.

And Kelly Hall felt even more that Peng Zhengge was playing the game of war, so that Rolls-Royce and Honeywell International could compete with each other to lower prices.

At the Institute of Aeronautical Materials, where the manufacturing process of engine blades is underway.

Zhong Bing, the technical representative of Hongxin Group, said: "The blade rotates at a high speed. Any small, hidden metal breakage may cause the blade to break. Therefore, the blade must be integrally formed, and there cannot be a second or third casting process!"

Gao Wei nodded and said, "We also have a one-piece design, but there is a problem. Among titanium-aluminum alloys, titanium is too active and reacts with almost all metals and ceramics. For one-piece molding, we must find a suitable shaping container!"

Zhong Bing carried the spherical quantum computer with him. He turned on the projection and said, "There are three kinds of ceramics that do not react with titanium. One is thorium oxide, which is radioactive and cannot be used as a stereotype container; the second is calcium oxide, which absorbs moisture. , cannot be preserved; only yttrium oxide can be used as a shaping container."

"We have also considered this." Gao Wei wondered, "Yttrium oxide is used as a shaping container. Its surface is powdery, and it is easy to drop slag and contaminate the titanium-aluminum solution, so that the precision of the formed titanium-aluminum blade is not enough. "

"That's right!" Kelly Hall happened to hear this and interjected: "We used computer simulations in the Aeronautical Materials Laboratory in Germany to calculate that titanium-aluminum alloy blades longer than 200 mm cannot be integrally formed. No matter what we do , will encounter the problem that the yttrium oxide slag will affect the accuracy."

"That's not necessarily true. Computer simulations can also make mistakes." Zhong Bing said.

Kelly smiled: "I just reminded that if you fail, we are willing to sell some technical materials to help you complete the material manufacturing of titanium and aluminum alloys. As for blades longer than 200mm, I advise you not to delay."

"What we want to manufacture today is a titanium-aluminum alloy blade that exceeds 200mm." Zhong Bing said directly.

Kelly Hall shrugged and didn't speak again, but the expression on his face already showed his thoughts, and he was waiting for the good show.

"Let's start. Prepare titanium-aluminum solution and yttrium oxide solution." Zhong Bing shouted, and the working groups began to act.

"Mr. Lu, can you do it?" Peng Zhengge asked Lu Zixin in a low voice, "Today, I called the representatives of Rolls-Royce and Honeywell. If I fail, I won't be able to hang on my face!"

"Don't worry, today, you can see titanium-aluminum alloy blades appear, and they definitely exceed 200mm." Lu Zixin assured.

There is no problem with the titanium aluminum solution, the most important thing is the manufacture of the yttrium oxide shaping container! As long as the yttrium oxide shaping container is made, and then the titanium aluminum solution is poured into it, it can be integrally formed.

Gao Wei has always been worried that they have done similar experiments countless times. Every time it fails due to various reasons, especially the problem of slag loss in the yttrium oxide forming container, which has led to the accuracy of the titanium aluminum alloy blade has not been up to the standard, so far they have not found a solution.

To make the yttrium oxide stereotype container, when smelting the yttrium oxide solution, Zhong Bing asked someone to fetch a bucket of sealing solution.

"What is this?" Gao Wei asked curiously.

"A molecular binder, specially used for yttrium oxide, can make its surface smooth and stable without slag falling off." Zhong Bing said, let people add the molecular binder to the yttrium oxide solution and carry out Forming of yttrium oxide shaped containers.

After a while, when the solution cooled, the styling container appeared! Different from the results of previous experiments, this time, the yttrium oxide shaping container did not appear in the state of surface particles and powder, but was as smooth as a mirror!
