MTL - The Black Technology Chat Group of the Ten Thousand Realms

A few days later, in the foreign guest reception room of Huaxia Commercial Aircraft Manufacturing Co., the representative of Honeywell International of the United States, Anderson Vogels, and the representative of the British Rolls-Royce, Kelly Hall, were negotiating and waiting.

Their purpose is the same, in order to sell the technical information of engine blade materials to Huaxia Commercial Aircraft Manufacturing Co., as soon as possible. The two sides are competitors, and it is inevitable to try each other and find the bottom line of each other.

"Two, I have kept you waiting." Peng Zhengge came out from the door and said.

"Peng Zong!" The two stood up and shook hands with him, and they were 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 does not need to refuse either party, the other party will naturally understand.

"Before talking about cooperation, I would like to invite two of them to visit our Institute of Aeronautical Materials. Today is the day we test the latest low-pressure turbine blades, and please also visit the two." Peng Zhengge said.

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

"It's a great honor." Kelly also expressed his interest.

On the road, Kelly Hall has also emphasized with Peng Zhengge the importance of their blade material technology.

“Now we are using the new titanium-aluminum alloy blades for the aero engines manufactured by Air Rolls for Airbus. The improved fuel efficiency has greatly enhanced the competitiveness of commercial aircraft. Airbus a350-800, a350- The 900, a350-1000 and the a350-900ulr under development will use the aircraft engine made of this blade material."

“And Airbus relies on this fuel-efficient model to obtain a large number of orders from around the world to compete with the Boeing 787-9 and 777-200er aircraft for the market. If Huaxia Commercial Aircraft Manufacturing Company can use this new material instead Nickel-based alloy blade materials, the market competitiveness can certainly be more than doubled!"

“Mr. Hall is the same as we thought. Our idea is to apply this new material to the aero engine as early as possible. Therefore, the purchased aero engine also uses this new material.” Peng Zhengge said.

“Yes.” Kelly Hall continued to sell and said: “If we can cooperate on the manufacture of such materials, your company will no longer have to spend a lot of money on this material, but can make it on its own. ""

He finished, Anderson also said: "We Honeywell is also willing to cooperate."

"Two, waited for the material testing of the Institute of Aeronautical Materials, let's talk about this issue again." Peng Zhengge said in a mysterious tone.

Anderson heard his tone, and inexplicably had a bad feeling. Just like the large-area molding technology of carbon fiber composites before, did they encourage them this time?

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

Kelly Hall, I feel that Peng Zhengge is playing in the heart, so that Luo Luo will compete with Honeywell International to lower prices.

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

Zhong Bing, technical representative of Hongxin Group, said: "The blade rotates at high speed. Any small, hidden metal breaks may cause the blade to break, so the blade must be integrally formed, and there must be no second or third casting process!"

Gao Wei nodded and said: "We are also a one-piece design, but there is a problem. In titanium-aluminum alloy, titanium is too active, almost reacts with all metals and ceramics. In one-piece molding, we must find a suitable shaped container!"

Zhong Bing carried a spherical quantum computer with him. He opened the projection and said: "There are three kinds of ceramics that do not react with titanium. One is yttrium oxide, which is radioactive and cannot be used as a shaped container. The second is calcium oxide, which absorbs moisture. Can't save; only yttrium oxide can be used as a styling container."

"We have also considered this." Gao Wei wondered, "Oxide is a shaped container, its surface is powdery, it is easy to slag, pollute the titanium aluminum solution, so that the titanium aluminum blade after molding is not accurate enough. ”

“Yes!” Kelly Hall happened to hear this and interjected: “We used computer simulations in the aerospace materials laboratory in Germany to calculate that titanium-aluminum alloy blades longer than 200 mm could not be integrally formed. No matter what. , will encounter the problem of the accuracy of the **** slag."

"That's not necessarily. Computer simulation, it will also go wrong." Zhong Bing said.

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

"Today we are going to manufacture more than 200mm titanium-aluminum alloy blades." Zhong Bing said directly.

Kelly Hall shrugged and didn't talk any more, but the expression on his face showed his thoughts, and he was waiting to watch the show.

"Get started. Prepare titanium aluminum solution, yttrium oxide solution." Zhong Bing shouted, the working groups began to act.

"General Lu, can you do it?" Peng Zhengge whispered to Lu Zixin. "Today, I called the representatives of Rolls-Royce and Honeywell. If they fail, they can't stand on their faces!"

"Do not worry, today, you can see the appearance of titanium aluminum alloy blades, and definitely more than 200mm." Lu Zixin assured.

There is no problem with the titanium aluminum solution, the most important is the manufacture of yttrium oxide shaped containers! As long as the yttria-shaped container is made, the titanium-aluminum solution is poured in, and it can be integrally molded.

Gao Wei has been worried that they have done it many times in similar experiments. Every time it failed for various reasons, especially the problem of **** slag-type container slag, resulting in the accuracy of titanium-aluminum alloy blades has not met the standard, so far they have not found a solution.

To make a yttria-shaped container, when smelting the yttrium oxide solution, Zhong Bing took a bucket of sealing solution.

"What is this?" Gao Wei was curious.

“A molecular adhesive, specially used for yttrium oxide, can make its surface smooth and stable without slag.” Zhong Bing said that people can add molecular binder to cerium oxide solution. Molding of a cerium oxide shaped container.

After a while, the styling container appeared when the solution cooled! Different from the results of many previous experiments, this time, the yttrium oxide shaped container does not appear as a surface particle or powder state, but is as smooth as a mirror!
