A few days later, in the foreign guest reception room of China Commercial Aircraft Manufacturing Company, Anderson Fogus, a representative of Honeywell International of the United States, and Kelly Hall, a representative of Rolls-Royce of the United Kingdom, were negotiating and waiting.
Their purpose is the same, to sell the manufacturing technical data of engine blade materials to China Commercial Aircraft Manufacturing Company as soon as possible. The two parties are competitors, and it is inevitable to test each other and find the other party's bottom line.
"You two, I kept you waiting for a long time." Peng Zhengge came from the door and said.
"Mr. Peng!" The two stood up and shook hands with him, both eager to know the decision of China Commercial Aircraft Manufacturing Company.
Generally speaking, this kind of thing should be discussed separately, because no matter which party is rejected, it will be more embarrassing. But Peng Zhengge is not worried about this problem today, because he does not need to reject either party, and the other party will naturally understand.
"Before discussing cooperation, I would like to invite you two to visit our Aerospace Materials Research Institute. Today is the day when we test the latest low-pressure turbine engine blades, and I would like to invite you to visit together." Peng Zhengge said.
"That's good, I'm interested too," Anderson said.
"It's an honor." Kelly also expressed his interest.
On the way, Kelly Hall also kept emphasizing to Peng Zhengge the importance of their blade material technology.
"Now all the aero engines manufactured by Rolls-Royce for Airbus use this new type of titanium-aluminum alloy blades. Its improved fuel efficiency has greatly enhanced the competitiveness of commercial aircraft. Airbus A350-800, A350- 900, A350-1000 and the A350-900ULR under development will all use aircraft engines made of this blade material.”
"Relying on this fuel-efficient model, Airbus has received a large number of orders from around the world and competes with Boeing 787-9 and 777-200ER passenger aircraft for the market. If China Commercial Aircraft Manufacturing Company can use this new material, it will replace Nickel-based alloy blade materials will definitely more than double their market competitiveness!”
"Mr. Hall has the same considerations as us. Our idea is to use this new material in aero-engines as soon as possible. Therefore, the aero-engines purchased also use this new material." Peng Zhengge said.
"Yes." Kelly Hall continued to promote and said: "If we can cooperate in the manufacturing of this material, your company will no longer have to spend a lot of money on this material in the future, but can manufacture it by itself. ”
After he finished speaking, Anderson also said: "We at Honeywell are also willing to carry out such cooperation."
"You two, let's talk about this issue after we visit the material testing at the Aeronautical Materials Research Institute." Peng Zhengge said in a mysterious tone.
Hearing his tone, Anderson had an inexplicable feeling. It was like the previous large-area molding technology of carbon fiber composite materials. Could it be that they had tinkered with it again this time
impossible? If Hongxin Group has already developed carbon fiber composite materials for other high-tech equipment manufacturing, but this time the materials are only used in aircraft engine blades! It is unlikely that R&D technology will be available in advance.
Kelly Hall, on the other hand, felt that Peng Zhengge was playing a psychological game to further allow Rolls-Royce and Honeywell International to compete and lower each other's prices.
Arriving at the Aeronautical Materials Research Institute, the manufacturing process of engine blades is in progress.
Zhong Bing, the technical representative of Hongxin Group, said: "The blades rotate at high speed, and any small, hidden metal fractures may cause the blades to break, so the blades must be formed in one piece, 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 reactive and reacts with almost all metals and ceramics. For one-piece molding, we must find a suitable shaping container!"
Zhong Bing brought a spherical quantum computer with him. He turned on the projection and said: "There are three types of ceramics that do not react with titanium. One is thorium oxide. Thorium is radioactive and cannot be used as a shaped container; the second is calcium oxide, which absorbs moisture. , cannot be preserved; only yttrium oxide can be used as a shaped container."
"We have also considered this." Gao Wei said doubtfully, "Yttrium oxide is used as a shaping container. Its surface is powdery, and it is easy for slag to fall off and contaminate the titanium-aluminum solution, so that the formed titanium-aluminum blades are not accurate enough. "
"That's right!" Kelly Hall happened to hear this and interrupted: "In the aerospace materials laboratory in Germany, we used computer simulations to calculate that titanium-aluminum alloy blades longer than 200 mm cannot be formed in one piece. No matter how we do it, , will encounter the problem of yttrium oxide slag affecting accuracy. "
"That's not necessarily true. Computer simulations can also make mistakes," Zhong Bing said.
Kelly smiled and said: "I'm just reminding you that if you fail, we are willing to sell some technical data to help you complete the manufacturing of titanium-aluminum alloy materials. As for blades longer than 200mm, I advise you not to waste time."
"What we are going to manufacture today are titanium-aluminum alloy blades exceeding 200mm." Zhong Bing said directly.
Kelly Hall shrugged and said no more, but the expression on his face already revealed his thoughts. He was waiting for a good show.
"Let's get started. Prepare titanium-aluminum solution and yttrium oxide solution." Zhong Bing shouted, and the working groups began to take action.
"Mr. Lu, can you do it?" Peng Zhengge asked Lu Zixin in a low voice, "Today I called up the representatives of Rolls-Royce and Honeywell. If I fail, I won't be able to show off my face!"
"Don't worry, today, you can see the appearance of titanium-aluminum alloy blades, and they will definitely exceed 200mm." Lu Zixin assured.
There is no problem with the titanium-aluminum solution. The most important thing is the manufacturing of the yttrium oxide shaping container! As long as the yttrium oxide shaping container is made and the titanium-aluminum solution is poured into it, it can be formed in one piece.
Gao Wei has been worried that they have done similar experiments countless times. Each time it failed due to various reasons, especially the problem of slag falling out of the yttrium oxide shaping container, which caused the accuracy of the titanium-aluminum alloy blades to not meet the standards. So far, they have not found a solution.
It was time to make a shaped container for yttrium oxide. When smelting the yttrium oxide solution, Zhong Bing asked someone to get a bucket of sealing solution.
"What is this?" Gao Wei asked curiously.
"A molecular adhesive is specially used for yttrium oxide, which can make its surface smooth and stable without falling slag." Zhong Bing said, and asked people to add the molecular adhesive to the yttrium oxide solution, and conduct Forming of yttrium oxide shaped containers.
Not long after, when the solution had cooled, the shaping container appeared! Different from the results of many previous experiments, this time, the surface of the yttrium oxide shaping container no longer appears in a granular or powdery state, but is as smooth as a mirror!
