Chapter 228 Hurry to find Wang Xudong

These two people are not simple, they are both senior experts, one is a senior expert in the field of materials, and the other is a senior expert in the field of aero-engines.

Lin Yunwen, as a senior expert in the field of China's aero-engines, is in charge of the development of a national key model of aero-engines. Currently, he has encountered major difficulties, especially in terms of materials.

The progress of this aero-engine was good at the beginning. Not only has the design been successfully completed, but also the trial production of the first verification machine has been completed. This verification machine has also been tested on the test bench. However, from the test run situation, Not ideal.

After careful analysis by the entire scientific research team, the problem was not in the design, nor in the manufacturing process, but in the material. The material was not up to standard, and the verification test almost failed.

Taking advantage of his friend Xu Jiaxiang's birthday this time, Lin Yunwen specially took the time to come here. Congratulations on Xu Jiaxiang's 50th birthday is one aspect. On the other hand, which is the most important, Lin Yunwen wants to seek Xu Jiaxiang's help.

It's a pity that when Lin Yunwen explained the situation, Xu Jiaxiang also felt very exhausted and helpless. This is a key model of aero engine, and the requirements for materials are very strict. Even Xu Jiaxiang has no way to solve this material problem.

Lin Yunwen was full of disappointment, and now he was in a slightly depressed mood. He was about to leave Jiangnan Province and continue his own research after returning. Lin Yunwen even had such a plan. If he really couldn't solve the material problem, he could only change the design structure and lower the requirements. However, in this way, the overall performance of this aero engine will drop a lot.

Helpless, there is no way, it seems that the overall performance of the aero engine can only be sacrificed, Lin Yunwen thought so dejectedly.

Wang Xudong could hear the content of the two people's chat clearly. Wang Xudong turned around and looked at the two people curiously. Wang Xudong saw that Xu Jiaxiang patted Lin Yunwen's shoulder lightly as a comfort, and then lightly Sigh lightly.

Wang Xudong's heart moved. He is one of the shareholders of Sanlian Special Steel. It is a remarkable thing to purchase from the local party and apply it to military products.

Eight out of ten domestically produced aero engines are used by the military. That is to say, if the special steel of Sanlian Special Steel can be used in aero engines, the heaviest user is the military.

Wang Xudong really wanted to say loudly, I can solve your problems, but Wang Xudong knew that if he really said that, the other party might think he was crazy if he didn't believe him or not.

Knowing this in his heart, Wang Xudong was very strategic. With a friendly smile on his face, he looked at the two of them and struck up a conversation: "You are experts, please. We are not in a hurry."

There were quite a lot of people checking in, and Wang Xudong's team was lined up with several people. Lin Yunwen and Xu Jiaxiang were right behind Wang Xudong.

Lin Yunwen said: "Young man, it doesn't matter, first come first come first, you should go first."

Wang Xudong had a good impression of Lin Yunwen and Xu Jiaxiang. Seeing that Wang Xudong was young and polite, the two had a good impression of Wang Xudong.

Just now, when the two of them were chatting, they paid great attention to confidentiality. They probably knew that this was a public place, and at most they only mentioned key models, what aero-engines, troubles, etc., and never mentioned materials. Engine model, verification test details and so on.

However, Wang Xudong guessed that the two probably encountered difficulties in transporting materials. Sanlian Special Steel should start to smelt the first furnace of super stainless steel soon, so Wang Xudong wanted to sell it to the two.

Wang Xudong really hit the spot.

Wang Xudong said: "You two, the Sanlian Special Steel Group in Wujiang City is about to smelt the world's most advanced super stainless steel. This is a very remarkable stainless steel material. Not only is it absolutely first-class in corrosion resistance, but it also has good mechanical processing. Performance, super mechanical structure strength, I wonder if you two are interested in it?"

Lin Yunwen's eyes lit up, but soon his eyes dimmed. He sighed slightly and thought to himself, I have never heard of Sanlian Special Steel. I guess this so-called super stainless steel is not much better, so I don't want it. hopeful.

Lin Yunwen presided over the research and development of this aero-engine, and encountered two major material problems, one of which was the problem of stainless steel materials.

Generally speaking, titanium alloy materials are widely used in the compressor part of aero-engines, because this material is corrosion-resistant, has a small specific gravity, light material, and high mechanical strength, and is the preferred material for cold parts such as compressors.

However, titanium alloy is not perfect, and has a fatal shortcoming, that is, it is not resistant to high temperature. To improve the overall performance of this aero-engine, it is necessary to increase the compression ratio in design. The higher the compression ratio, the higher the compressor level. The compressed air, as the air is compressed step by step in the compressor, the temperature also rises step by step, and the temperature of the next few stages of the compressor reaches several hundred degrees, which exceeds the limit of the titanium alloy. Made of stainless steel.

High-quality stainless steel materials are also corrosion-resistant and have good mechanical strength. The only point is that the specificity is larger. In order to improve the compression ratio and the overall performance of the engine, although the stainless steel material has a larger specificity, compared with the overall performance improvement , is totally worth it.

Of course, the material problem encountered by this new type of aero-engine is not limited to stainless steel, but also a high-temperature material, but if any of them can be solved, it will definitely be a huge surprise for Lin Yunwen.

It's a pity that Lin Yunwen didn't believe it, and he didn't believe that the Sanlian Special Steel that Wang Xudong said he had never heard of could develop stainless steel materials that could meet the needs of advanced aero-engines.

Lin Yunwen is well aware of the stringent material requirements of aero-engines, especially advanced aero-engines.

Seeing that Lin Yunwen didn't believe it, Wang Xudong just shook his head lightly and didn't continue the conversation. Wang Xudong's meaning was obvious, I've given you the opportunity, and if you don't believe it and lose this opportunity, that's your own problem.

"Brother Dong, it's our turn."

Liu Yu yelled at the front, Wang Xudong smiled, and did not continue to chat with Lin Yunwen, but took a few steps forward and began to help Zheng Xiaotong check in, got the boarding pass, and the three of them walked towards the waiting hall together .

When they walked to the gate of the waiting hall, Zheng Xiaotong obviously looked sad, because they were about to separate soon, and Zheng Xiaotong was going back to the capital, and the two of them would not see each other again for at least a week.

"Brother..."

Zheng Xiaotong's eyes suddenly turned red, and big tears were about to flow down. Wang Xudong was very distressed when he looked so pitiful.

Wang Xudong hugged Zheng Xiaotong lightly, and kissed Zheng Xiaotong lightly on the forehead, how could he know that Zheng Xiaotong had a huge reaction, hugged Wang Xudong and kissed him proactively.

There are many people at the airport. If it was normal, according to Zheng Xiaotong's personality, he would definitely not take the initiative to kiss Wang Xudong in such a place, but thinking that he is going back to the capital soon, after returning, he still doesn't know what his family thinks about his future marriage. Regarding attitude, Zheng Xiaotong has no idea whether to accept Wang Xudong or not.

Zheng Xiaotong knew that his father had a good impression of Wang Xudong, but apart from his father, his mother obviously didn't like Wang Xudong. In addition, the Zheng family was such a big family that it was different from ordinary people's. The attitude of others.

More importantly, Zheng Xiaotong also knew that his grandfather hadn't said anything so far. Although he didn't object, he didn't support him either. If his grandfather didn't support him being with Wang Xudong, what should he do?

It is precisely because of all kinds of worries in his heart that the separation is imminent, Zheng Xiaotong's reaction is so great, Wang Xudong seems to understand, and while being moved in his heart, he secretly said, no matter how much resistance he encounters, he must be Xiaotong in front of him. Together.

The two kissed together and separated after a long time. Liu Yu was very self-conscious. He dragged his suitcase and left a long time ago. A plane.

Zheng Xiaotong said with red eyes: "Brother Dong, no matter what, we must be together and never separate, okay?"

Wang Xudong nodded firmly and said, "Well, no one can separate us. After the Chinese New Year, I must come to the capital. I want to propose marriage to the Zheng family, and I want to marry you."

After receiving Wang Xudong's firm answer, Zheng Xiaotong was so moved that he wiped away his tears in Wang Xudong's arms, and broke into a smile.

Wang Xudong gently stroked Zheng Xiaotong's beautiful hair, and said affectionately: "Little fool, the plane is about to take off, you can go in quickly, and call me when you arrive in the capital."

"En." Zheng Xiaotong nodded.

.........

Lin Yunwen also completed the check-in procedures, because it was still early before the boarding time, Lin Yunwen and Xu Jiaxiang were chatting, and hadn't entered the waiting hall yet.

Lin Yunwen said: "Old Xu, that young man just now is really strange. I don't believe what he said about triple special steel and super stainless steel. I guess it's just ordinary stainless steel, just a commodity."

Xu Jiaxiang nodded and said, "I guess it's the same."

The two chatted, and after chatting for a few words, Xu Jiaxiang suddenly seemed to remember something, and after being stunned for a while, he suddenly said: "Old Lin, I remembered this Sanlian special steel. I have a friend, Ding Huixian, you You know, he went to Sanlian Special Steel."

Ding Huixian is a metallurgical expert. Before that, he invented a super-strong steel that won the National Science and Technology Progress Award. In addition, Ding Huixian was from Jiangnan Province, and Xu Jiaxiang was also from Jiangnan Province. The two had known each other for a long time and had a good relationship.

A metallurgical expert, a material expert, and metallurgy and materials are closely related. Xu Jiaxiang and Ding Huixian have a good relationship and are completely normal. Not long ago, the two even met for a meal. Ding Huixian said that he went to Sanlian Special Steel , as the chief expert of Sanlian Iron and Steel, Xu Jiaxiang was surprised at the time.

Now that I think about it, Sanlian Special Steel is the steel company that Ding Hui served as the chief expert. Immediately, Xu Jiaxiang became inexplicably excited and had a hunch in his heart that this super stainless steel was really not simple.

With a slightly excited tone, Xu Jiaxiang said: "Old Lin, hurry up, don't rush back by plane, let's go find that young man just now, hurry up!"
