Chapter 1751 Popular Science
Rotstosky looked at Gao Yang and said slowly: "So, what are the bargaining chips that are really useful to you? They are the basic materials."
Gao Yang really didn't understand these things. He said curiously: "Basic materials?"
Rotstosky nodded and said, "That's right, for a country, especially an industrial country, basic materials are the most important, especially metal basic materials. This is the industrial foundation of a country, high-end equipment manufacturing industry, and the industrial crown of a country, but you have to have materials to form this crown."
Gao Yang nodded without understanding, and Rotstosky continued to smile: "China has developed very quickly in recent years, and the research on gas turbines has not been slow. However, it is still necessary to import some key components from Ukraine. Why?"
Gao Yang shook his head and signaled that he didn't understand.
Rotstosky smiled and said, "Because there is a lack of basic technology at some key points, the basic materials industry requires large investment and long-term research can make some results. Being rich and investable is one aspect, and more importantly, it takes time, and people who don't understand can't see the results. They think this is a useless industry. Huaxia has been developing rapidly over the years. Logically speaking, Huaxia can use reverse engineering technology to make any complex equipment, such as the aviation engine that has plagued China's development over the years, but why should China suffer such trouble?"
Gao Yang whispered: "I really don't know how important the basic materials are, because I haven't understood them before."
Rotstosky smiled and said, "Let me give an example. Once, I was ordered to obtain the key technology of an engine in the United States. Finally, we got a turbofan engine and handed it to a certain organization for reverse research. At that time, the direction of technology development was already very clear. On fighter jets, the turbojet engine will be replaced by a turbofan engine. So the engine I was ordered to bring back was highly valued, and they copied the engine. But do you know what the result was in the end?"
“What’s the result?”
Rotstosky shook his head and said helplessly: "They perfectly copied the engine, but the power of the engine is two levels different from the original product. Why? Because the rotor material of the turbofan is not up to standard, because the blade material of the turbofan is not strong enough and cannot withstand ultra-high temperature and high pressure, the full power output will cause damage. However, it can be used only if it is actively reduced to the output power, but it is two levels worse than the performance of the original product."
Gao Yang nodded and said loudly: "So that's the case, but since you have obtained the physical object, isn't it enough to do it according to the physical object? Isn't metallographic analysis very difficult, right? I don't understand this, don't laugh."
All the black devils laughed.
Grevatov smiled and said, "It's not like this, it's not as simple as you think."
Rotstosky smiled and said, "Let me explain it. Even if you get a physical object, you can also analyze the specific ingredients, but even if you use the same material, you still cannot achieve the same effect."
Rotstosky waved to Grevatov and said, "Give me a piece of paper and a pen, I'll explain it to him."
After taking the paper and a pen, Rotstosky drew on the paper and said with a smile: "The same material, different manufacturing processes and different processes, will have completely different performances. For example, let me give you the simplest example. A certain type of steel contains iron, nickel, chromium, tungsten, and manganese. There are only a few materials. You have obtained the physical object and learned the ingredients through analysis. However, you don't know when the tungsten component should be added. Simply put, should the key casting part be added together? Or should you add nickel at 1,000 degrees Celsius of the base material, and then add manganese at 1,200 degrees Celsius, or the other way around."
Gao Yang said silly: "Is it very important?"
Rotstosky nodded and said, "Yes, it's very critical, very critical. A small difference may lead to a huge difference in the properties of this material. There is no error in the research on basic materials. The failure of one direction may mean the success of the other direction. Sometimes, a material with superior performance may be just because of luck, but it's really luck that leads to the discovery and use of a brand new material."
Gao Yang sighed, "It's so complicated."
Rotstosky smiled and said, "It's really complicated. It requires long-term investment, no output for a long time, and it also requires a lot of money to work. To be honest, the research on basic materials, especially high-end basic materials, is to burn money."
Glevatov said lightly: "The material used in the aircraft engine is at least dozens of alloys, and some components can only account for less than one ten thousandth of them. However, if this material is lacking, the performance will immediately vary greatly. Therefore, unless you can get all the means of production related to this material, you can get materials with similar performance. As for the same, it is impossible, or better, or worse than the original product. Why? Because this involves another major field, which is the problem of manufacturing process level and the problem of purification process level, which involves a series of problems, which is very complicated."
Rotstosky smiled and said, "So no matter how fast China is developing and how rich it is, sometimes it has to be subject to some seemingly inconspicuous small problems, because after it involves high-end basic materials, you can only study it slowly, try it slowly, and experiment it bit by bit, and it takes time."
Glevatov said expressionlessly: "Justice, the service life of the Soviet fighter engine is 1,000 hours, while the US engine life is more than 10,000 hours. This is a different understanding of war and a result of different use and research concepts of equipment. However, if it can be improved, it will not be too expensive. Of course, we hope to extend the interval between overhaul and increase the service life, but it is not possible. The materials are not as good as the United States. However, the Soviet Union surpassed the United States in the use of titanium alloys. For example, using titanium alloy to make nuclear submarines, the United States is not as good as the Soviet Union. Is the United States not as strong as the Soviet Union? Is the United States not as strong as the Soviet Union? Is the United States not well developed enough? None of them, they just haven't found the right direction yet. Maybe one day, they will do it suddenly because they have made a breakthrough."
Gao Yang nodded repeatedly and said, "Thank you for your popular science. Now I understand, that is, I should start with this?"
