Mercenary War

Rotzowski looked at Gao Yang and said slowly: “So, what is the really useful chip for you? It is the basic material.”

Gao Yang, but I really don’t understand this. He is curious: “Basic materials?”

Roztoski nodded: “Yes, contact with materials, for a country, especially an industrial country, basic materials are the most important, especially metal base materials, which is a country’s industrial base. High-end equipment manufacturing is a national industrial crown, but you have to have materials to form this crown.”

Gao Yang nodded and seemed to understand. Rootstoski continued to laugh: “Huaxia has developed rapidly over the years, and the research progress of gas turbines is not slow. However, some key components still need to be imported from Ukraine. ,why?”

Gao Yang shook his head and motioned that he didn’t understand.

Rootstoski smiled: “Because there is a lack of basic technology at certain key points, the basic materials industry needs a lot of investment. Long-term research can yield some results. It is one thing and more important to invest. Time, and people who don’t know it, can’t see the results. I think this is an industry that has no use. Huaxia has developed rapidly these years. It is reasonable to say that China can use reverse engineering technology to make any complicated equipment, such as These years have been plagued by the development of China’s aviation engines, but why, China is suffering from such troubles?”

Gao Yang whispered: “I really don’t know how important the basic materials are, because I didn’t know about them.”

Rotzowski said with a smile: “I will give an example. Once, I was ordered to get the key technology of an engine in United States. Finally, we got a turbofan engine and handed it over to one of our agencies. In the reverse research, at that time, the direction of technological development was already clear. On the fighter jet, the turbojet engine would be replaced by a turbofan engine, so the engine that I was ordered to bring back was highly valued. They copied the engine, but finally Do you know what the result is?”

“What results?”

Rotzowski shook his head and said with a slight helplessness: “They perfectly copied the engine, but the power of the engine is two grades worse than the original. Why? Because the rotor material of the turbofan is not closed, Because the blade material of the turbo fan is not strong enough to withstand the ultra-high temperature and high pressure, the full power output will cause damage. The active reduction of the output power can be used barely, and the performance from the original product is worse than two grades.”

Gao Yang nodded, loudly said: “It turned out to be like this, but since you have obtained the real thing, can you do it according to the same material? Metallographic analysis is not difficult? I don’t understand this, don’t laugh. ”

Several black devils all laughed.

Gleevav laughed: “Not like this, not as simple as you think.”

Rotzowski said with a smile: “Or let me explain, this kind of high-end metal material, you get the real thing. And you can analyze the specific ingredients, but even if you use the same material, Can’t achieve the same effect.”

Rotztoski waved at Grevatov: “Give me a piece of paper, a pen, let me explain it to him.”

After taking the paper and the pen, Rotztoski drew a picture on the paper and smiled: “The same materials, different manufacturing processes, different processes, will have very different performance. For example, I will give the easiest For example, a certain kind of steel, containing iron, nickel, chromium, tungsten, manganese, just like several materials, you have obtained the physical object. The composition is known through analysis, but you do not know the composition of tungsten in it. When to join, in simple terms, the key part of the casting process is to add all the materials together? Or when the base material is a thousand degrees Celsius, add nickel, then add manganese when it is one thousand two, or vice versa. It.”

Gao Yang is stupid: “Is it critical?”

Rootstoski nodded: “Yes, it is critical, very critical. A small difference may lead to a great difference in the performance of this material. The study of basic materials is not wrong, failure in one direction. It may mean success in another direction. Sometimes, a material with superior performance may be just because of luck, it is really just luck that leads to the discovery and use of a new material.”

Gao Yang sighed: “It’s so complicated.”

Rotztoski smiled: “It’s really complicated. It’s a long-term investment, a long-term output, and a lot of money. Really, basic materials, especially high-end basic materials, are research. Burn money.”

Gleevtof faintly said: “A certain material used on aircraft engines is at least dozens of alloys, and some components can only account for less than one ten thousandth. However, the lack of this material, the performance is immediately worse. No, so unless you can get all the production materials about this material, it is possible to get materials with similar performance. As for the same, it is impossible, or better, or not as good as the original, why? Because this involves another A large area is the problem of manufacturing process level and the level of process technology of purification. This involves a series of problems and is very complicated.”

Rootstoski smiled: “So, China’s development is fast, there is money, and sometimes it has to be subject to some seemingly insignificant problems. Because it involves high-end basic materials, you can only slow yourself. Slow research, try slowly, experiment a little bit, and it takes time.”

Grevatov said with a blank expression: “Like the Soviet engine, the life of the engine is one thousand hours, and the engine life of the United States has reached more than 10,000 hours. This is a different understanding of the war, but also the equipment. The results of the use and research philosophy are different, but if we can improve the service life and not too expensive, we certainly hope to extend the interval between overhauls and increase the service life, but not, the material can not match the United States, and the Soviet Union The use of titanium alloys, but more than the United States, such as the use of titanium alloys to make nuclear submarines, United States is not as good as the Soviet Union, United States national strength is not as good as the Soviet Union? United States technology is not developed enough? No, they just have not found the right direction, Maybe one day, they will suddenly do it because they got a breakthrough.”

Gao Yang nodded and said: “Thank you for your science. Now I understand, that is, I should start in this regard?”

Rootstoski nodded: “Yes, you should pay attention to this, and you are very lucky, because I can tell you what is really good in Ukraine, especially the good things for you.” (~^ ~) Mobile phone users please visit http://m.piaotian.net
