Chapter 468: Who counts if you fail?

    By cutting off the beginning and ending in this way, the Americans not only kept their core secrets, but also achieved so-called openness and transparency, and even partially paralyzed their competitors.

    Because there are indeed several chasing countries that took advantage of public reports from the Americans and used carbon fiber resin composite materials to load the missile body. As a result, one bomb was blown up, two bombs were bombed, and the wallets were really blown up.  Helplessly gave up.

    The Soviets should say that they were not deceived by the Americans. This is not to say that the Americans¡¯ composite materials are not good, but that the Soviet Union is rich in resources and has advanced alloy smelting technology. There are several alloy materials suitable for long-range missiles, regardless of  The quality and performance are not much worse than the composite materials that the United States has painstakingly produced.

    Therefore, the Soviet model is really difficult to copy. In addition to the extremely high technical threshold, you must have a mine at home. It is not just one kind, but almost covers most of the naturally derived minerals in the periodic table of elements.

    Only the Soviet Union, which spanned the Eurasian continent, could do it several times in the entire world. None of the others could do it, not even Russia later.

    Not to mention domestically, neither the Soviet Union nor the United States can compare. Coupled with the strict technological blockade of the two superpowers, such high-value materials are not available not only domestically, but also by established powers such as Britain and France.  They do not have the technology for industrial mass production and can only obtain a small amount of finished products from the United States.

    The Soviet Union doesn¡¯t even give you finished products. If you want it, no problem. There are a lot of long-range missiles of various SSs. As long as you follow the big brother, I guarantee that you can sleep peacefully next to the missiles.

    Under such circumstances, it is extremely difficult to make fiber-reinforced metal matrix composite materials. Let¡¯s not say goodbye. Various metals and matching fiber materials must be familiar with their properties. This process is not just a list of chemistry in middle school.  Equations are enough, but they need to be narrowed down to molecules or even the arrangement and combination of atoms.

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

    Then the corresponding fiber and metal matching is 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 a long journey of thousands of miles, including fiber preparation, mixed metal fusion, technology, equipment, and stable industrial production. A series of things is simply not too much.

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

    Japan is relatively fast. It has been keeping pace with the United States since the 1960s and the late 1970s. 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 high-level part-time worker in the United States in the global division of labor system of the United States.  young.

    It is also true that Americans¡¯ metal matrix composite materials follow a robust industrial preparation route; while Japan takes another high-risk route with higher technology content and greater investment.

    ??In commonly used words in China, it is one goal and two paths. Under uncertain circumstances, try both with funds.

    "If we were in China, we might allocate two funds in order to produce results quickly, but it would be much more convenient to go to the United States. We would do some of the work at home and leave the rest to Japan.

    ???????????????????????????????????????????????????????????????????????????????????????????????????????????????? When Japan has results, they will just use them. Do the Japanese dare to say no?  The muzzles of the US military stationed in Japan are not vegetarian.

    "The country does not have the convenience of Americans to share funds, let alone their strength. There is no other way but greed. Even the country is helpless, and Ascendas Airlines naturally does not have this ability.

    But how come so many metal matrix composite materials were suddenly produced?

    It¡¯s very simple, it was forced out by mistake.

    In addition to carbon fiber composite materials, the aviation technology R&D center under Ascendas Aviation Corporation is focusing on titanium-aluminum alloys. As the main material for turbine blades in the next ten to twenty years, titanium-aluminum alloys have extremely high temperature resistance.  Once successful, the total temperature at the engine combustion chamber outlet can be increased to about 1600k (i.e. 1327 degrees Celsius).

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

    Based on this, the high-thrust aeroengine will reach a very considerable thrust value. Once a breakthrough is made in the core aircraft, the supersonic cruise of stealth fighters, the large bomb load and long range of bombers, the intercontinental flight of transport aircraft, and the supersonic flight of large civilian airliners will be achieved.  High demands are no longer a problem.

    However, the vision of the future is beautiful, but the road ahead is tortuous. At the beginning, Company H was searching for Japanese technical resources.It was messy at first. Although Zhuang Jianye found a few promising technologies in it, it was generally just a prototype, or even a good idea.

    For example, the electrochemical drilling device used to manufacture film cooling holes in aircraft engine turbine blades is a typical representative; titanium-aluminum alloy is better than the electrochemical drilling device, but it is only slightly better.

    So when Song Yanan led a large number of technicians to make titanium-aluminum alloy samples based on Japanese materials with great interest, there was no joy, only frustration.

    Because apart from high temperature resistance, the other properties of titanium-aluminum alloys are simply terrible. The longitudinal strength is acceptable but the transverse strength is very weak. Not to mention running at high speed on an aero-engine turbine, even if it is knocked with a vise, it will deform.  .

    That¡¯s all. The low-temperature performance is not up to standard, and the material is easily brittle. It¡¯s fine for other uses, but if it¡¯s placed on an aero engine, severe hot and cold changes can easily cause it to break.

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

    How about saying that the public technical data of some Western developed countries are deceptive. They only highlight high-temperature resistance and talk about this in a lavish way. They don¡¯t mention anything else, and then they just watch others fall into this pit.

    "It is said that the Soviet Union's war situation is powerful. Compared with the guys in the West who dig holes and bury them, the Soviet Union's war situation is as innocent as a young girl who has just grown up.

    Tengfei Aviation Technology R&D Center encountered such a cheating problem. The titanium-aluminum alloy in its current state is simply not suitable for the high requirements of aeroengines, let alone the core turbofan blades, and other general materials are not suitable.  Promotion.

    If this was placed in other research units, they might have given up. It didn¡¯t succeed anyway. If you don¡¯t stop the loss quickly, why are you waiting? But the corporate culture of Ascendas Airlines is 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 salary of scientific researchers at all. They only care about the huge returns brought by the commercial conversion of research and development projects, because they will get a few percentage points of sales share from it. Compared with this, according to the regulations designated by the ministries and commissions  The fixed salary is just like pocket money, and few people care about it.

    Because of this, Song Yanan and others were not only disappointed but also deeply unwilling to look at the titanium-aluminum alloy. It felt like they had finally harvested crops, only to find that the crops were crooked, cracked, and difficult to sell.

    what to do?  Naturally, I want to find ways to repackage, improve the appearance, and try to sell things through other channels. After all, the most delicious thing is still small money, and failure is considered a failure.
