Chapter 135: Surge
"If these materials can pass your extreme tests and the data is ideal, they can be directly connected to the factory for production!"
"Okay, okay. I'll arrange it as soon as the materials arrive and send you the latest data immediately. I sincerely invite you to become the chief consultant of WS-15 and help us make it better!"
The position of chief consultant was second only to that of chief engineer. Before this, Yang Wei had never given up the position. But now, Yang Wei only wanted to repay Wu Tong with the best conditions he could offer.
If the WS-15 generation had not been finalized during its difficult development in the past two years, he would have wanted to give the position of chief engineer to Wu Tong.
"Mr. Yang, you are too polite. 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!"
Even without her, with Ms. Yang's tireless and continuous efforts in research, it is possible to achieve this result. She just used her best to speed up the process.
"In fact, I should thank you for the trust and authority you gave me, which gave me the opportunity to access those confidential data. I also learned a lot in the process. It can be said that you have integrated and sublimated the things I had learned in a disorganized manner before. I should be grateful to you!"
As for the core data of WS-15, there are few sources in China that can provide such a comprehensive overview.
This involves knowledge in many areas. During the six months since Wu Tong came to Peking University, he has attended many classes. In addition to basic mathematics, he has covered everything from physics to chemistry, from materials to engineering.
Studying and researching WS-15 materials is also an improvement of Wu Tong's studies in these subjects. Deducing and improving on this basis is equivalent to special advanced training. Wu Tong has truly gotten started in these subjects.
Especially for materials, Wu Tong got the list of advanced study books carefully compiled for her by Mr. Cheng, and repeated the preparation process. Without the tension of the first preparation, Wu Tong began to carry out intensive study whenever she had time. Day by day, her understanding of materials science became more and more profound, which was incomparable to before.
If nothing unexpected happens, with continued research and study, materials science may become the most superior subject after Wu Tong's mathematics.
Not everyone who reads the information can have this sublimation ability. Wu Tong’s talent is the most crucial point.
Think about Wu Tong's world-class achievements in mathematics, one after another. Maybe in her eyes, this is commonplace, a skill that everyone can have? It seems that a certain classmate's cognition may be a little biased, but this is not important, and Yang Wei does not deliberately emphasize it.
After making a gesture to the assistant engineer to continue verifying, Yang Wei returned to the office anxiously and loaded the encrypted document that Wu Tong had transferred to her.
He then discussed with Wu Tong some of the questions they had encountered during the research and preparation process in recent days, as well as the process and principles of Wu Tong's material preparation.
Aircraft engines are difficult, and blade preparation is definitely the first priority.
He did not fully understand the key points and difficulties here, pretended to know them, and rushed to arrange and prepare for the test, which might have caused a disaster and wasted Wu Tong's efforts.
Wu Tong carefully explained the basis of her deduction at the time. After receiving guidance from Academician Xie and supplementary courses in materials science, she had a rich theoretical reserve and could use scientific language to explain the absolute deduction that immersed her body and mind that night, but she only knew the results but not the reasons.
"Aircraft engine blades are generally cast from alloy materials, and single crystal technology is currently the most superior technical choice. When the material is cast, molecules and atoms combine to form grains, which are arranged outward with the crystal nucleus as the core in the early stage of casting."
Yang Wei nodded and explained the difficulty: "Because there is no external force, the arrangement will be chaotic and irregular, and there will be broken fracture zones between the grains, resulting in inconsistent melting points and force-bearing capacity in different parts of the entire crystal.
Due to the non-uniform distribution of this shape, two difficult problems arise here. The first is that the various parts of the entire engine blade are still subjected to uneven forces. The second is that some parts will naturally bear much more heat than other parts.
When it is made into an engine blade, it will break and disintegrate instantly due to its high temperature environment of over 1500°!"
"Yes, Mr. Yang, you are an expert in aircraft engines, so the engine blades I deduced are single crystal blades! The arrangement of the grains in these blades must be very orderly. On this basis, I deduced and designed a new nickel-iron material model, which will perform very well in temperature and mechanical properties under certain conditions!" Questions and answers extended each other, and Wu Tong and Yang Wei discussed carefully and attentively.
"This problem is not so easy to solve. Most alloy materials have a low melting point and cannot withstand high temperatures above 1500°. The interior of the single-crystal blades of an aircraft engine must also be made into a hollow shape with various grooves, right?" As the chief designer of WS-15, Yang Wei has been deeply involved in this area for many years and knows the difficulty best.
Only by improving the melting point and strength of the alloy material at the same time can we make a truly qualified engine single crystal blade. Otherwise, they would not have been stuck for so many years. The many difficulties of the material are also the key factor that is fatal.
"Yes, based on the atomic and molecular sequence, I transformed and deduced the metal rhenium that is suitable for enhancing the melting point and strength of the alloy."
Wu Tong's absolute direction and absolute deduction allowed her to screen out and determine that the key material was metal rhenium.
The melting point of this metal is as high as 3180℃, and its tensile strength exceeds 1172MPa, which is equivalent to bearing a weight of 117 tons per square centimeter without deformation.
In addition, the most amazing thing about this metal is that it basically does not expand or contract when switching between high temperature and rapid cooling and heating conditions. The engine nozzle made of this material can withstand 100,000 thermal fatigue cycles, making it a good choice for aviation materials.
However, 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 based on the material and combined his abilities to deduce the most appropriate material ratio.
"I rearranged the order of molecular atoms to retain 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 heat cycle fatigue resistance of metal rhenium. I got the best material that can be achieved with current technology, and it is relatively low in cost, the T5 nickel-iron alloy blade material."
After receiving Wu Tong's precise answers, Wu Tong took the opportunity to ask Yang Wei some questions about engineering dynamics. After they exchanged ideas, they both hung up the phone contentedly.
High temperature resistance of 2400°, tensile strength, corrosion resistance, fatigue resistance of 1710MPa, and light weight... There is no more suitable blade material than this. Seeing the detailed data of the T5 alloy's advantages, Yang Wei's blood boiled in an instant, and he returned to the excitement of the WS-15 design back then, or even higher!
