Chapter 466: How Old Is Failure?
With such a pinching of the head and the tail, the Americans not only kept their core secrets, but also achieved so-called openness and transparency, and even played a role in partially paralyzing their competitors.
Because there are really a few countries that are chasing behind take the public reports of the Americans and use carbon fiber resin composite materials to load the bomb body, and as a result, one is fried, and two are fried, and the wallet is deflated, so I have no choice but to give up.
It is not that the Americans' composite materials are not good, but that the Soviet Union is rich in resources, has developed various alloy smelting technologies, and has several alloy materials that meet the requirements of long-range missiles, and their quality and performance are not much worse than the composite materials that the United States has worked so hard to make.
So the Soviet model is really difficult to replicate, in addition to the ultra-high technical threshold, you must have a mine at home, not one, but almost covering most of the naturally derived minerals in the periodic table.
Several times the whole earth, only the Soviet Union, which straddled the Eurasian continent, could do it, and the rest were counted as one, and none of them had that ability, even if it was later Russia.
As for the country, not to mention, whether it is the Soviet Union or the United States, there is no comparison, coupled with the strict technological blockade of the two superpowers, such high-value materials, not to mention the domestic, even the old powers such as Britain and France can not get the technology of industrial mass production, and can only obtain a small number of finished products from the United States.
The USSR, not even the finished product, you want, no problem, there are a lot of long-range missiles of all kinds of SS, as long as you follow the big brother, it is guaranteed that you can sleep peacefully lying on the side of the missile.
In this case, it is difficult to make fiber-reinforced metal matrix composites, not to mention other things, all kinds of metals, supporting fiber materials, must be familiar with their properties, this process is not to learn a few chemical equations, but to narrow down to molecules, and even the arrangement and combination of atoms.
Experimentation, accumulation, and analysis are a long and difficult process.
Then the corresponding fiber and metal matching are generated, and it is a series of experiments, accumulation, and analysis......
On the contrary, these processes are only the first step in a long march of thousands of miles, fiber preparation, mixed metal fusion, processes, equipment and stable industrial production, a series of things that are simply not too much.
The Americans have been doing research in this area since the fifties of the twentieth century, and it was not until the late seventies and early eighties that the initial industrialization was achieved.
The problem is that Japan's rapid progress is inseparable from the support of the United States, after all, Japan has always been a high-level wage earner in the United States in the American division of labor system.
In fact, the Americans' metal matrix composites have taken a robust industrial preparation route, while Japan's has taken a more high-risk route with higher technology content and greater investment.
In the words commonly used in China, it is one goal, two paths, and in the case of uncertainty, both take the funds to try it.
If it were at home, it might allocate two funds in order to produce results quickly, but it would be much more convenient for the United States, and the country would make a mess and throw the rest to Japan.
Each has its own expense, and when the time comes, Japan will directly bring it to the Japanese when it has achieved results, and the Japanese will dare to say a word? The muzzles of the US troops stationed in Japan are not vegetarians.
There is no convenience for Americans to share expenses in China, let alone the strength of the family, and there is no other way but to be greedy, and even the country is helpless, and the Tengfei Aviation Corporation naturally does not have this ability.
But why did you suddenly come up with so many metal matrix composites?
It's very simple, the crooked beating is being forced out.
In addition to carbon fiber composite materials, the main direction of the aviation technology research and development center under Tengfei Aviation Corporation is titanium aluminum alloy, as the main material of turbine blades in the next ten to twenty years, titanium aluminum alloy with its extremely high temperature resistance, once successful, the total temperature of the engine combustion chamber outlet can be increased to about 1600K (that is, 1327 degrees Celsius).
If combined with the advanced air mold cooling system and the ceramic thermal insulation spraying material on the surface, the total temperature of the engine combustion chamber outlet can be increased to more than 2000K (that is, 1763 degrees Celsius).
On this basis, a high-thrust aero engine will reach a very considerable thrust value, once a breakthrough in the core aircraft is achieved, the supersonic cruise of stealth fighters, the large bomb load and long range of bombers, the intercontinental flight of transport aircraft, and the high requirements of large civil airliners are no longer a problem.
However, the vision of the future is beautiful, but the road ahead is tortuous, when the H company searched for Japanese technical data, it was disorganized, although Zhuang Jianye found a few potential technologies from it, but on the whole it was only a prototype, and even a good idea.
For example, the electrochemical perforation device used for the manufacture of air film cooling holes in aero engine turbine blades is a typical representative, and the titanium aluminum alloy is better than the electrochemical perforation equipment, but it is so much better.
Therefore, when Song Yanan led a large number of technicians to make samples of titanium aluminum alloy according to Japanese data with great interest, there was no joy, only frustration.
Because in addition to the high temperature resistance of titanium aluminum alloy, the other properties are simply terrible, the longitudinal strength is okay, but the transverse strength is weak, not to mention running at high speed on the aero engine turbine, it will be deformed when knocked with a vice.
That's it, the low-temperature performance is also unqualified, the material is easy to embrittle, and it is good for other uses, but if it is placed on an aero engine, the drastic cold and heat changes are easy to break.
In other words, purebred titanium-aluminum alloys have no commendable advantages except for high temperature resistance and high price.
How else to say that the public technical information of some western developed countries is pitiful, just highlighting the high temperature resistance, saying this article is out of the blue, and nothing else is mentioned, and then quietly watching others jump in this deep pit.
It is said that the war situation in the Soviet Union is very powerful, and compared with the guys who dig holes in the West and don't bury them, the war situation in the Soviet Union is as innocent as a girl who has just grown up.
Tengfei Aviation Technology R&D Center has encountered such a pitfall, titanium aluminum alloy in its current state is not suitable for the high requirements of aero engines, not to mention the core turbofan blades, that is, the general materials on other parts are not promoted.
If this is placed in other research units, maybe it will be given up, anyway, it is not successful, what are you waiting for if you don't stop the loss quickly, but the corporate culture of Tengfei Aviation Corporation pays attention to the investment must have a return, and it must be a high return on super profits.
Especially in the research sector, the salaries of scientific researchers are not looked at at at all, they only care about the huge returns brought by the transformation of the goods of the research and development projects, because they will get a few percentage points of sales share from them, compared to the fixed salary designated by the ministry is like pocket money, and few people care.
Because of this, Song Yanan and others looked at titanium aluminum alloy in addition to disappointment and deep unwillingness, it felt like the crops that were finally harvested, but it turned out that the crops were crooked and cracked, and the mood was the same.
Naturally, I want to find a way to repackage, improve my appearance, and strive to sell things in other channels, after all, the most fragrant is still a small amount of money, and failure is considered an old man.
