Take Off My Aviation Era

So Song Yanan led the team to start the improvement of titanium and aluminum alloys. At first, they had no goals, they just walked inertially towards the alloy.

Fortunately, as an export-oriented enterprise, Ascendas Aviation Corporation attaches great importance to the collection and sorting of foreign language technical data, especially the technical developments in aerospace in Europe, America, Japan and other countries. Core journals will be ordered through Hong Kong Island as long as there is no accident. , Transferred back to China.

Therefore, although Song Yanan and others have no direction, they have enough references. Among them, several articles briefly introducing metal matrix composites have given them great inspiration.

A closer look revealed that it is a bit difficult for Ascendas Aviation Technology R&D Center to go in the direction of alloys, but it seems easier to try fiber-reinforced metal matrix composites.

This would be incredible if it were in other materials research institutes. If those who do materials have no metallurgical skills, what kind of materials will they do?

But in the serious take-off aviation technology research and development center of the branch, metallurgy is precisely their weakness, even if the half-dead titanium aluminum alloy is based on Japanese technical data, it is made at a high price.

In other words, in addition to titanium and aluminum, Ascendas Aviation Technology R&D Center has very general control of other metal materials. If it is alloyed, it is tantamount to starting from scratch. Not to mention the time and effort, the investment will be doubled.

But if fiber-reinforced metal matrix composites are used, the advantage of Ascendas Aviation Technology R&D Center is obvious, because they are mainly engaged in carbon fiber composite materials, and their understanding of various carbon elements and their compounds is not generally thorough. Not to mention, how to condense carbon fiber is the unique job of Ascendas Aviation Technology R&D Center.

If metal elements can be incorporated into carbon fiber to generate more excellent composite materials and improve the characteristics of titanium and aluminum alloys, will there be broad application prospects?

Now that the general hardware is available in the Aerospace Technology R&D Center, the only difference is the fusion process of carbon fiber and metal elements. There is nothing to say, just stick your arms and do it.

Of course, this time Song Yanan and the others did not directly use titanium aluminum alloy. Instead, they started with simple aluminum and tried to combine with aluminum element with the best t300 carbon fiber to produce aluminum-based composite fiber filaments in order to confirm their theory.

This confirmation has been confirmed for more than a year. Finally, after breaking through the chemical vapor deposition technology and fiber calcination technology, the aluminum-based fiber filaments that meet the requirements are made, and then the stacked fiber filaments are made into carbon fiber reinforced aluminum by high temperature and high pressure. Base composite materials have undergone a series of actual tests and tests.

Found that the performance of carbon fiber reinforced aluminum matrix composites is not generally good, so I quickly reported to Zhuang Jianye as a briefing. While introducing the new achievements of the aviation technology research and development center, it is recommended to apply the discovered carbon fiber reinforced aluminum matrix composites to The main bearing structure of the aircraft or the general parts of the gas turbine engine.

Zhuang Jianye, who saw this briefing, was also taken aback. Others didn’t know about carbon fiber reinforced aluminum matrix composites. Doesn’t he, a man who has lived for two lifetimes, still know?

In fact, I did not expect that the Aviation Technology R&D Center would have such a big battle, and I was surprised and even more excited.

Because once this composite material science and technology tree is lit, the technological leap of the future aerospace is almost inestimable, let alone other, if the aluminum base is replaced with a carbon base, the carbon fiber reinforced carbon-based composite material will be produced at once. Mentioned another new height.

How tall is it?

Decades later, the most mysterious X-37b low-Earth orbit vehicle covered by the US military is made of carbon fiber reinforced carbon-based composite materials.

If it is replaced with a ceramic base, it is even more serious, because of the natural high temperature resistance and high strength, it is an excellent material for the surface of the warhead of a super high-speed attack weapon.

As the so-called one pass Belden, as long as you go down this road, Ascendas Aviation Corporation can stand still and watch various composite materials synthesized by carbon fiber in the aerospace field.

What else to say, just throw in the money, so 20 million was allocated to the Aviation Technology R&D Center without saying a word, specifically for the research of carbon fiber reinforced metal matrix composite materials, of which 10% of the funds were used as project incentives Funds are used for rewards and subsidies for scientific research team members.

10% of 20 million is 2 million. Just after the results came out, I got 2 million before commercial conversion. So let alone Song Yanan and the others who are going for small money, let alone the excitement. In the past year or so It was worth the hard work, so while ensuring the progress of carbon fiber composite materials, the research on titanium-based composite materials and other aluminum-based composite materials was quickly started.

And quickly completed the development of silicon carbide fiber-reinforced titanium-based composite materials and silicon carbide fiber-aluminum-based composite materials, but encountered unprecedented difficulties in carbon fiber-reinforced titanium-based composite materials.

In this regard, Zhuang Jianye did not urge Song Yanan and the others, because carbon fiber reinforced titanium-based composite materials are a worldwide problem. As the best material for the fan blades of turbofan engines in the future, Rolls-Royce of the United Kingdom Almost broke.

General Motors of the United States was also almost exhausted because of this material, relying on continuous blood transfusions from the powerful financial system of the United States to survive and finally completed a breakthrough in this field.

This material is used for the fan blades of the ge90 large bypass ratio turbofan engines on the Boeing 777 and Boeing 787. Compared with the traditional titanium alloy material, the weight is reduced by more than 30%, but the strength is increased. More than doubled that after a high-speed impact of a 1.5 kg bird, the blade was not damaged in the slightest and continued to work normally, showing extremely strong safety.

Once the performance of the ge90 engine came out, it became another explosion after the gf6 engine.

Even Rolls-Royce and General Motors are dying because of the carbon fiber-reinforced titanium-based composite materials. The volume is not as big as a fingernail-sized Ascendas Aviation Corporation, so they dare not let go. They can only guarantee generality. I dare not bet on my value.

In fact, I just want Ascendas Aviation Corporation to gamble, because the previous three metal matrix composite materials have almost exhausted the old foundation of Ascendas Aviation Corporation, so Zhuang Jianye looks like a okay person during this period. Yes, in fact, I was thinking all day about how to make money.

Whether it is an opinion of financial service support or an attitude of all-out disaster relief, to put it bluntly, it is Zhuang Jianye's means of seeking funds and policies.

Needless to say, financial services ~www.readwn.com~ is directly linked to funds; all-out disaster relief seems to be a loss, but the policies given by superiors are better than one. As long as they are used well, these policies can be quickly transformed into substance Help reduce business costs.

Even if it is now taking a naval expert team to investigate the d-50 gas turbine power plant of the Ascendas Aerospace Power, its purpose is also the same.

If the d-50 gas turbine power unit can be sold, it would be good. If not, so many good materials will be placed here. The Navy and the Second Artillery have long-range missiles. It is just a proper need. Can you give me some money? With policy support, you can't let Ascendas Aviation Manufacturing Corporation do its own work, right?

I thought it was a long and arduous process, but I never thought that Director Zhao jumped out with excitement as soon as he had just started, and helped himself to explain the basic situation of carbon fiber reinforced aluminum matrix composites, which saved Zhuang Jianye. A lot of tongues, as for the effect, just look at the expression of Song Changzheng, with shock in the dazedness, and unspeakable excitement and excitement hidden in the shock.

Finally stared at Director Zhao and said in a trembling tone: "Old Zhao, what you said is true? The second stage instrument bracket and the third stage of the American Trident 2 submarine-launched missile are all carbon fiber reinforced. Made of aluminum-based composite materials?"
