As Zhuang Jianye said that, he stuffed the huge guide blade in his hand to the head of the Aero Engine Manufacturing Factory in front of him. The head of the Aero Engine Manufacturing Factory was really surprised because the guide blades looked quite large, and they were half the size of a forearm. In addition, this thing faced the so-called strongest front-turbine high temperature between the combustion chamber and the turbine. It was generally made of nickel-based alloy combined with complex cooling ring channels. It was not as light as ordinary aviation components in weight.

So when Zhuang Jianye suddenly came over, he really scared the person in charge of the Aerospace Engine Manufacturing Factory. If one of them was not caught, who would fall to the ground?

If it were just him and Zhuang Jianye, it wouldn't matter. If it could not be taken, it would not be taken. Anyway, this thing was not his. The problem was that the chief engineer, deputy director and many other brother factories were here at this moment. The head of the Aerospace Manufacturing Factory was not good enough, but he had to maintain a certain image, so he was really shocked.

But as a result, the head of the Aerospace Engineering Manufacturing Factory was not only not angry because of Zhuang Jianye's reckless behavior, but instead held the huge guide blade with one hand and was filled with incredible eyes, and then his lips trembled twice: "Why is it so light?"

Yes, in the past, guide blades made of completely metal such as nickel-based alloys were not heavier than steel of the same volume, but they were not much lighter.

Even if you admit that you can easily pick it up, you still need to support it with some effort.

But at this moment, although the shape and volume of the guide blades on your hand are no different from the previous ones, the overall weight is at least one-third lighter than the guide blades made of traditional nickel-based alloys.

You should know that the main focus of the factory where the Aerospace Engine Manufacturing Factory, who holds the guide blades in his hand, is the most core thermal components of aircraft engines such as guide blades and turbine blades, because he is not only aware of the weight of such components but also extremely sensitive.

As soon as you start, you will know that Tengfei Group's products are much lighter than the products in their factory.

What does it mean to be so lightweight with the same volume and shape?

First, we will make decisive breakthroughs in materials, and secondly, we will achieve disruptive innovations in processing technology. None of them can be used to lack either.

However, before the head of the AVF manufacturing factory came back to his senses from the light guide blades, another head of the AVF factory snatched the guide blades, and then looked over and over for a while. That was not counting. He even called his assistant, took out the magnifying glass he carried with him and looked carefully on the surface for a while, then looked up at Zhuang Jianye in disbelief: "There is no cooling hole on your blade? Use the material to resist directly? Even if the ceramic material has a strong resistance to high temperature, the oxidation resistance of the ceramic material is very poor, and its ductility itself is even worse. The combination of the two causes the strength to be worse than that of different low-carbon steels. At the same time, the heat flow that just ejected from the combustion chamber is fierce and unstable, and the impact is very strong. How did you do it? Not only that..."

I don’t know if the head of the Aviation Engine Factory was really surprised or curious. He asked a series of questions at Zhuang Jianye like a gun, which confused the heads of other Aviation Engine Factory around him, but none of them came out to stop him, including the deputy director and the head of the Aviation Engine Factory who fought with Zhuang Jianye.

The reason is very simple, because they also discovered that there are really no complicated air film cooling holes on this guide blade.

When I checked the WD-66 large bypass ratio turbofan engine before, this detail was not noticed by them. It was not that they did not look carefully, but that this type of air film cooling hole is extremely small, and there will be different degrees of oxidation reactions during high-temperature shock and burning during the operation of the aircraft engine, resulting in black and dirty surfaces of the blades, and the location of the air film holes is slowly identified, so it is normal not to notice it.

But now, the blade that Zhuang Jianye took out is brand new, without any trace of burning or oxidation, and naturally they will be discovered by seniors in the aerospace industry at a glance.

But because of this, except for Zhuang Jianye and the chief engineer, the rest of the people present were counted and none of them were shocked. The guide blades that faced the temperature in front of the turbine did not have an air film cooling hole, and they directly used the material itself to eat high temperatures above 1,300 degrees Celsius.

Such a simple and crude approach, let alone the deputy director and others, were incredible when they saw it, but the core aeroengine engineers of the three major aeroengine giants, General Motors, Puhui, and Rolls-Royce, would also feel their scalp numb when they saw it.

How strongly does the material itself have to reach to be to dare to eat the absolute high temperature before the turbine so hard?

You should know that the structure of nickel-based alloys is no longer stable at 1,100 degrees Celsius. If not, aerospace engineers would not have developed a cooling structure that is as complex as the air film cooling hole. But even so, the temperature will be increased to 1,300 degrees Celsius at most, and no matter how high it is, there is nothing to do.

Therefore, in addition to further digging into the potential of nickel-based alloy single crystal structure materials and doing as much as possible to achieve this single crystal structure, the rest is to find ways to develop heat-resistant coating materials and apply a layer of skin on the nickel-based alloy blades.

However, whether it is to dig deep into the single crystal structure of the material or apply a layer of skin, the focus is on the nickel-based alloy itself.

In this regard, the United States, Europe and Russia are at the forefront of the world, but China is far behind. There is no way for those aviation powers to accumulate more than half a century in this regard, and their experience has accumulated to an explosion and are still moving forward.

Of course, China also wants to catch up in this regard, but the domestic aviation industry started late, and it has to wait until the first flight of Project No. 10, which is more than 40 years behind the aviation power as a whole.

The nickel-based alloy is a very experienced thing, especially the single crystal structure, the ratio of various metal elements, the temperature of smelting, the heat treatment procedures, etc., which cannot be solved overnight. It is the best solution that takes decades and tens of millions of tests to be summarized.

If not, how could those aviation powers dare to make the latest metallographic data of nickel-based alloys public as research results?

It’s not clear about the tricks here. Even if other countries know metallographic data, they cannot produce similar products, because the key to this kind of thing is not the data, but the entire production process.

Of course, other domestic aerospace manufacturers know this cruel reality, but they have no choice. If you want to chase it, it will take as long as 20 or 30 years. In other words, they will not see hope when they bring people.

If you don’t see hope, you will have no achievements. Without achievements, you will have no political achievements. You have reached this position. You are a cadre in charge of the central government. Who wouldn’t want to leave a strong mark in the future factory history?

But if you have the ability, what should I do?

So many factories took their attention to Russia or Ukraine, and used their aero-generating heating component manufacturing technology that was stronger than domestic aero-generating equipment and used it as a "domestic" installation machine.

Of course, the Russians are willing to make money, but the problem is that the quality control of the Russians is too poor, and their business reputation is also poor, which makes several domestic aerospace manufacturers want to die, but they can't say that they have any pain. Russia and Ukraine only look at money, but the United States and Europe are also dead, so even if the Russians are disgusting and fucking, domestic aerospace manufacturers will lose their teeth and swallow them into their stomachs.
