A few days later, in the Foreign Guest Reception Room of China Commercial Aircraft Manufacturing Company, the representative of Honeywell International, Anderson Forges, and the representative of Rolo, Kelly Hall, were discussing and waiting.
They had the same purpose, which was to sell the manufacturing technology of the engine blade material to China Commercial Aircraft Manufacturing Company as soon as possible. Both parties were competitors, and it was inevitable for them to test each other's bottom line.
"Sorry to keep you waiting." Peng Zhengge walked in and said.
"Mr. Peng!" Both of them stood up and shook hands with him. They were 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 was rejected, it would hurt the other party's reputation. But today, Peng Zhengge was not worried about this problem, because he did not need to reject either party, and the other party would naturally understand.
"Before we talk about cooperation, I would like to invite both of you to visit our Aviation Materials Research Institute. Today is the day we test the latest low-pressure turbine engine blades, and I would like to invite both of you to visit together. "Peng Zhengge said.
"That's great, I am also interested." Anderson said.
"It's an honor." Kelly also expressed his interest.
On the way, Kelly Hall kept emphasizing the importance of their blade material technology to Peng Zhengge.
"Now, the aircraft engines that Rolo is manufacturing for Airbus are all using this new type of titanium alloy blades. It improves the fuel efficiency and greatly enhances the competitiveness of commercial aircraft. Airbus A350-800, A350-900, A350-1000 and the A350-900 ULR in development will use this type of blade material to manufacture aircraft engines. "
"And Airbus relied on this type of fuel efficient aircraft model to obtain a large number of orders from all over the world, competing with Boeing 787-9 and 777-200ER airliners for the market. If China Commercial Aircraft Manufacturing Company can use this new type of material to replace the nickel-base alloy blade material, the market competitiveness will definitely increase by more than double! "
"Mr. Hall is thinking the same thing as us. We also want to use this new type of material in aircraft engines as soon as possible. So, we will also use this new type of material to purchase aircraft engines. "Peng Zhengge said.
"Yes." Kelly Hall continued to promote and said: "If we can cooperate on the manufacturing of this type of material, your company will not need to spend a lot of money on this type of material in the future, and you can manufacture it yourself."
As soon as he finished speaking, Anderson said, "Honeywell is also willing to cooperate with you."
"Let's talk about this after we visit the Aerospace Materials Research Institute," Peng Zhengge said mysteriously.
When Anderson heard his tone, he inexplicably had a bad feeling. It was just like the large area forming technology of carbon fiber composite materials. Could it be that they had come up with something again this time?
Impossible, right? Hongxin Group had already developed carbon fiber composites for other high-tech equipment. But this time, the material was only used for aircraft engine blades! It was unlikely that they would have the research and development technology in advance.
As for Kelly Hall, he felt that Peng Zhengge was playing a psychological battle. He wanted Luoluo to compete with Honeywell International and lower the price.
When they arrived at the Aerospace Materials Research Institute, the research institute was in the process of manufacturing engine blades.
Zhong Bing, the technical representative of Hongxin Group, said, "The blades are rotating at high speeds. Any small, hidden metal fracture may cause the blades to break. Therefore, the blades must be formed as one piece. 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 the titanium and aluminum alloys, the activity of titanium was so strong that it reacted with almost all metals and ceramics. We must find a suitable container for forming the blades! "
Zhong Bing carried a spherical quantum computer with him. He turned on the projection and said, "There are three kinds of ceramics that do not react with titanium. The first is thorium oxide. Thorium is radioactive and cannot be used as a container. The second is calcium oxide. Calcium oxide absorbs moisture and cannot be stored. Only yttrium oxide can be used as a container."
"We have considered this." Gao Wei was puzzled. "If yttrium oxide is used as a container, its surface is powdery. It is easy to drop slag and contaminate the titanium and aluminum solution. As a result, the precision of the formed titanium and aluminum blades is not high enough."
"That's right!" Kelly Hall happened to hear this and interrupted, "In the Aerospace Materials Research Institute in Germany, we used computer simulations to calculate that titanium and aluminum alloy blades longer than 200mm can not be formed as one piece. No matter how we do it, we will encounter the problem of yttrium oxide dropping and affecting the precision. "
"That is not necessarily true. Computer simulations can also be wrong. "Zhong Bing said.
Kelly smiled and said, "I am just reminding you that if you fail, we are willing to sell a part of the technical information to help you complete the manufacturing of titanium and aluminum alloy. As for the blades longer than 200mm, I advise you not to waste time. "
"What we are going to manufacture today is titanium and aluminum alloy blades longer than 200mm." Zhong Bing said directly.
Kelly Hall shrugged and did not speak again. However, the expression on his face revealed his thoughts. He was waiting to watch a good show.
"Let's begin. Prepare the titanium and aluminum solutions, and yttrium oxide solutions. "Zhong Bing shouted and the working groups began to move.
"General Lu, can this work?" Peng Zhengge asked Lu Zixin in a low voice. "Today, I called the representatives of Luoluo and Honeywell. If we fail, we will lose face!"
"Don't worry. Today, you will see the titanium and aluminum alloy blades, and they will definitely be longer than 200mm." Lu Zixin guaranteed.
There was no problem with the titanium and aluminum solution. The most important thing was the production of the yttrium oxide container! As long as the yttrium oxide container was made, the titanium and aluminum solution would be poured in, and the blades would be formed as one piece.
Gao Wei had been worried. They had done similar experiments countless times. Every time, they failed due to various reasons. Especially the problem of the yttrium oxide container dropping, which caused the precision of the titanium and aluminum alloy blades to not meet the standards. Until now, they had not found a solution.
It was time to make the yttrium oxide container. When the yttrium oxide solution was being smelted, Zhong Bing asked someone to bring a bucket of sealed solution.
"What is this?" Gao Wei asked curiously.
"It is a type of molecular adhesive. It is specially used for yttrium oxide. It can make the surface smooth and stable without any droplets." Zhong Bing said and asked someone to add the molecular adhesive into the yttrium oxide solution to form the yttrium oxide container.
Not long after, when the solution cooled down, the container was formed! The results were different from the previous experiments. This time, the surface of the yttrium oxide container did not appear to be in a powdery state. It was as smooth as a mirror!
