Take Off My Aviation Era

With such a choke, the Americans not only kept their core secrets, but also achieved the so-called openness and transparency, and even played a part in paralyzing their competitors.

Because there are really a few countries that are catching up with public reports from the Americans. They used carbon fiber resin composite materials to mount the projectiles. As a result, they were blown up one by one, and two were blown up. It was really blown up until the wallet collapsed. Helplessly gave up.

The Soviets should not say that they have not been fooled by the Americans. This is not to say that the Americans’ composite materials are not good, but that the Soviets are rich in resources and have developed various alloy smelting technologies. There are several alloy materials suitable for long-range missiles. The quality or performance is not much worse than the composite materials produced by the United States.

Therefore, the Soviet model is really difficult to replicate. In addition to the ultra-high technical threshold, you must have mines in your home. It is not one, but almost covers most of the naturally derived mines in the periodic table.

Counting the entire earth, only the Soviet Union, which straddles Eurasia, can do it. There is only one left, which is not capable, even the later Russia.

Not to mention the domestic situation. Neither the Soviet Union nor the United States can compare. Coupled with the strict technical blockade of the two superpowers, this kind of high-value materials, not to mention domestic, is even the old powers such as Britain and France. No technology for industrialized mass production is available, only a small amount of finished products can be obtained from the United States.

The Soviet Union does not even give the finished product. You want it, no problem. There are a lot of long-range missiles of various SSs. Just follow the big brother to ensure that you can sleep peacefully while lying on the side of the missile.

Under such circumstances, it is simply difficult to make fiber-reinforced metal matrix composites. Let’s not say goodbye. Various metals and supporting fiber materials must be familiar with their properties. This process is not a matter of studying chemistry. The equation is fine, but it should be reduced to the permutation and combination of molecules or even atoms.

The experiment, accumulation, and analysis are a long and difficult process.

Then the corresponding fiber and metal match are generated, which is a series of experiments, accumulation, analysis...

Do you think this is over? On the contrary, these processes are only the first step in the long march. Fiber preparation, mixed metal fusion, process, equipment and stable industrial production are not too many.

Americans have been doing research in this area since the 1950s, and it was not until the end of the 1970s and the beginning of the 1980s that preliminary industrialization results were achieved.

Japan's speed is relatively fast. Since the 1960s and the end of the 1970s, it has been advancing side by side with the United States. The problem is that Japan's rapid progress cannot be separated from the support of the United States. After all, Japan has always been a senior part-time worker in the United States in the global division of labor. kid.

The fact is also true. The American metal matrix composites are taking a robust industrial preparation route; while Japan is another high-risk route with higher technological content and greater investment.

In common domestic terms, it is one goal and two roads. In the case of uncertainty, both have funds to try.

If you are in the country, you may allocate two funds in order to quickly produce results, but it is much more convenient for the United States, and the country makes a lot of money, and the rest is thrown to Japan.

All the funds are in charge. When the time comes, Japan will have the results and bring them directly. Do the Japanese dare to say nothing? The muzzle of the US military in Japan is not vegetarian.

China does not have the convenience of Americans to share the expenses, and there is no other person's strength. There is no other way but to be greedy. Even the country is helpless. Naturally, Ascendas Aviation Corporation has no such ability.

But why suddenly come up with so many metal matrix composite materials?

Quite simply, the crooked hit was being forced out.

In addition to carbon fiber composite materials, the aviation technology research and development center of Ascendas Aviation Corporation is mainly focused on titanium aluminum alloy. As the main material for turbine blades in the next ten to twenty years, titanium aluminum alloy has extremely high temperature resistance characteristics. Once successful, the total temperature of the engine combustion chamber outlet can be increased to about 1600k (1327 degrees Celsius).

And this is the temperature range that the blades can withstand under normal conditions of titanium-aluminum alloy. If combined with an advanced air cooling system and ceramic insulation spray material on the surface, the total temperature of the engine combustion chamber outlet can be increased to more than 2000k (1763 degrees Celsius).

On this basis, a large-thrust aero engine will reach a very considerable thrust value. Once a breakthrough is made in the core aircraft, the supersonic cruise of the stealth fighter, the large-loaded and long-range bomber, the intercontinental flight of the transport aircraft, and the large-scale civil aircraft High demands are no longer a problem.

However, the future vision is beautiful, and the road ahead is tortuous. When company h searched Japanese technical materials, it was messy and disorderly. Although Zhuang Jianye found several promising technologies from it, it was generally just a rudimentary form. It's even a good idea.

For example, the electrochemical perforation device used for the manufacture of film cooling holes for aero-engine turbine blades is a typical representative; titanium aluminum alloy is better than electrochemical perforation equipment, but it is just as good.

Therefore, when Song Yanan led a large number of technicians to make samples of titanium aluminum alloy according to Japanese materials, there was no joy, only depression.

In addition to high temperature resistance, the other properties of titanium aluminum alloy are simply terrible. The longitudinal strength is reasonable but the lateral strength is weak. Not to mention the high-speed operation on the aero engine turbine, even if it is knocked with a vise, it will deform. .

That’s all, the low-temperature performance is unqualified, the material is easy to be brittle, and it is good for other purposes, but if it is placed on an aero engine, the drastic cold and heat changes will easily break it.

In other words, pure titanium aluminum alloy has no commendable advantages except high temperature resistance and high price.

How about saying that some of the publicly available technical data of western developed countries are cheating, just highlighting the high temperature resistance, and talking about this one without mentioning anything else, and then quietly watching others jump in this pit.

It’s said that the Soviet Union’s sudden war situation is very powerful, compared with the guys who dig holes in the West ~ www.readwn.com~ The Soviet Union's war situation is innocent like a newly grown girl.

Ascendas Aviation Technology R&D Center encountered such a pitfall. In its current state, titanium aluminum alloy is not suitable for the high requirements of aero engines, let alone the core turbofan blades, that is, the general materials on other parts are not Promoted.

If this is put in other research units, they might give up. Anyway, it didn’t succeed. What are you waiting for if you don’t rush to stop the loss? The corporate culture of Ascendas Aviation Corporation emphasizes that the investment must be rewarded, and it must be super profitable. Amount of return.

Especially in the research department, no one cares about the salaries of scientific researchers. They only care about the huge returns brought by the conversion of products for research and development projects, because they will get a few percentage points of the sales share. Compared with this, according to the ministries and commissions. A fixed salary is just like pocket money, and few people care.

Because of this, Song Yanan and others looked at titanium and aluminum alloy in addition to disappointment and deep unwillingness. They felt like the harvested crops, and found that the crops were crooked and cracked. The mood is the same as it is not easy to sell.

How to do? Naturally, I think of a way to repackage, improve the appearance, and strive to sell things in other channels. After all, the most fragrant is the small money, and failure is considered an old man.
