Before returning to the college entrance examination, I became popular in the science circle

Chapter 135 Surging
"If these materials can pass your limit test and the data is satisfactory, they can be directly connected to the factory and put into production!"

"Okay, okay, as soon as the material arrives, I will arrange it immediately, and send you the latest data as soon as I have it. I sincerely invite you to become the general consultant of WS-15 and help us make it better!"

The chief counselor is the position second only to him as the chief engineer. Before that, Yang Wei had never promised it, but now, Yang Wei only wanted to repay Wu Tong with the best conditions he could offer.

If it weren't for the WS-15 generation, it would have been frozen when it was difficultly developed two years ago, and he wanted to give up the position of chief engineer to Wu Tong.

"Mr. Yang, you are welcome. Without the solid foundation you laid before, there would be no foundation for my deduction. I just stood on your shoulders and did some theoretical deduction work!"

Without her, with Mr. Yang's tireless efforts to study the pace, it may not be impossible to achieve this result. She just used her best to speed up the process.

"Actually, I should thank you for giving me the trust and authority to give me the opportunity to access those confidential data. I also learned a lot during this process. It can be said that I have learned a lot from here and there. Things, well integrated, mastered and sublimated, I should thank you!"

Regarding the core information of WS-15, there are few in the whole of China that can provide such a comprehensive overview of the overall situation.

Among them, many aspects of knowledge are involved. In the six months since Wu Tong came to Beijing University in advance, he really did not miss many classes. In addition to basic mathematics, he has dabbled in everything from physics to chemistry, from materials to engineering.

The research and study of WS-15 data is also an improvement study of Wu Tong's subjects. On this basis, the deduction is perfect, which is equivalent to special elevation training. Wu Tong is a real beginner in these homework.

Especially for the materials, Wu Tong got the list of refresher books that Chenglao carefully listed for her. She repeated the preparation process without the stress of concentrating on the first preparation. Wu Tong started to study intensively when she had time. Day by day, she mastered the materials. The understanding of learning has become more and more profound, which is not the same as before.

Not surprisingly, with continuous research and study, material science may become the most superior subject under Wu Tong's mathematics.

Not everyone who reads those materials can have this sublimation ability. Wu Tong's talent is the most critical thing.

Thinking about Wu Tong's world-class achievements in mathematics one after another, maybe in her opinion, this is something that everyone is accustomed to, an ability that everyone can master?I feel that a certain young student’s cognition may be a bit biased, but this is not important, and Yang Wei is not deliberately emphasizing it.

After gesturing to the assistant engineer to continue the verification, Yang Wei returned to the office anxiously and loaded the encrypted document that Wu Tong had transmitted to her.

Turning to Wu Tong, they discussed some doubts about their research and preparation process these days, as well as the process and principles of Wu Tong's material preparation.

Aeroengines are difficult, and blade preparation is definitely the most important and difficult point.

He did not fully understand the important and difficult points here and did not know how to pretend to understand. He rushed to prepare for the test, which was likely to cause disaster and wasted Wu Tong's hard work.

Wu Tong carefully explained the basis of her deduction at that time. After receiving the guidance of Academician Xie and the supplementary course of materials science, she has a rich theoretical reserve and can use scientific language to explain that she was immersed in body and mind that night, but only Absolute deduction of knowing why and not knowing why.

"Aero engine blades are generally cast from alloy materials, and single crystal technology is currently the most superior technology choice. When the material is cast, molecules and atoms combine to form grains, and these grains will use crystal nuclei as the initial stage of casting. The core is aligned outward.”

Yang Wei nodded and pointed out the difficulty, "Because there is no external force, the arrangement will be messy and irregular, and there will be broken fracture zones between the crystal grains, resulting in inconsistent melting points and force-bearing capabilities of various parts of the entire crystal. .

Due to the non-uniform distribution of this shape, there will be two serious and difficult problems here. The first is that the force on each part of the entire engine blade is still uneven, and the second is that some parts will naturally bear more heat than other parts.

When it is made into an engine blade, it will break and disintegrate instantly because it works in a high temperature environment above 1500°! "

"Yes, Mr. Yang, you are an expert in aero engines. Therefore, the engine blades I deduced are single-crystal blades! The arrangement of the crystal grains in these blades must be very orderly. On this basis, I deduced and designed a new type of The nickel-iron material model will perform very well in terms of temperature and mechanical properties under a certain continuation!" Questions and answers, extending each other, Wu Tong and Yang Wei discussed carefully.

"This problem is not that simple and easy to solve, right? Most alloy materials have low melting points and cannot withstand high temperatures above 1500°. The interior of the single crystal blade of the aero engine must be made into a hollow shape with a variety of ravines, right? "As the chief designer of WS-15, Yang Wei has been deeply involved in this sector for many years, and he is most aware of the difficulties involved.

Only by simultaneously strengthening the melting point and strength of alloy materials can we make truly qualified single-crystal engine blades.Otherwise, they wouldn't have been trapped for so many years.The many difficulties with materials are also a fatal key factor.

"Yes, based on the sequence of atoms and molecules, I transformed and deduced the metal rhenium that is suitable for strengthening and financial stores and strength."

Wu Tong's absolute direction and absolute deduction allowed her to screen and judge that the key material was metal rhenium.

The melting point of this metal is as high as 3180 ° C, and the tensile strength exceeds 1172 MPa, which is equivalent to bearing a weight of 117 tons on one square centimeter without deformation.

In addition, the most amazing thing about this metal is that there is basically no thermal expansion and contraction when switching between high temperature and rapid cooling and rapid heating. The engine nozzle made of this material can withstand 10 thermal fatigue cycles, and it is a better aviation material. choose.

It’s just that rhenium ore is rare and precious. Like titanium, no company or even country can afford to use rhenium metal to fully build blades. Wu Tong established a mathematical model on the right materials and combined his capabilities to deduce the most suitable materials. Proportion.

"I reorganized the order of molecular atoms and retained the advantages of various materials, such as the high resistance of titanium, the lightness of aluminum, the corrosion resistance of nickel iron, and the high temperature resistance and thermal cycle fatigue resistance of rhenium metal. The most superior material that can be achieved with technology and relatively low cost is T5 nickel-iron alloy blade material."

After receiving Wu Tong's precise answer, Wu Tong also took the opportunity to ask Yang Wei some questions about engineering dynamics and exchanged views with each other before the two hung up the phone in satisfaction.

2400° high temperature resistance, 1710MPa tensile resistance, corrosion resistance, fatigue resistance, and lighter weight... There is no more suitable blade material than this. Seeing the detailed data of the superiority of T5 alloy, Yang Weiyi In an instant, the blood boiled, and once again returned to the surge designed by WS-15, even higher!
