Take Off My Aviation Era

It is no wonder that the heads of several aviation manufacturing plants present have such an idea, it is that the domestic smelting and preparation of nickel-based alloys are too far behind the European and American aviation powers.

Not to mention them, they are the two brand-new aeronautical metal materials, X and Y, developed based on nickel-based alloys, doped metal rhenium and other rare high-temperature resistant metal elements, which are superior to the domestic Ascendas Group in terms of materials. If you want to truly mature and put into use, you will have to wait at least another five years.

After all, there is still a big difference between laboratory preparation and large-scale industrial production. The two new aviation metal materials, X and Y, must be used in aero engines no matter what, as industrial products must be mass-produced on a large scale. In the laboratory, I made a few samples and made a few limited editions. It was not an industrial product but a luxury product.

At present, the two brand-new Hangfa metal material cards of Ascendas Group X and Y are stuck in large-scale industrial preparation.

Even the Ascendas Group is like this, let alone other aviation manufacturers, it can only be more unbearable, otherwise it will not be able to buy so-called "domestic" goods from Russia and Ukraine.

Because of this, when they knew that there was a brand-new product that could surpass the impeccable nickel-based alloy material and complete the temperature leap in front of the aero engine turbine, the heads of several aviation manufacturing plants followed the innocent boy bathed by the goddess. The same, not to mention the exaggeration of blood spurting, but it is also very excited.

It’s just excitement to excitement. The people in charge of these aviation plants are not stupid. No matter how good the things of Ascendas Group, we must figure out whether this thing can be produced on a large scale, otherwise it will be advanced to make X and Y alloys. For companies like them eager to transform benefits, it's almost like taking off your pants and farting, and it's useless.

Therefore, the person in charge of the aviation development plant who asked a series of questions was surprised, but he was surprised, but also asked Zhuang Jianye in another way, this kind of high-pressure turbine guide blade made of ZBF-600 material Feasibility, don't be a custom model made by the laboratory, it's not interesting!

Zhuang Jianye is a wild fox that can be treated as a monkey spirit with his fur. The changes in the attitude of the people around him are naturally received by him, so he is not nonsense, and takes the other one from the staff next to him. The guide blades, and then took out two exquisite workmanship pins from the bottom of the upper and lower two outer support plates with the same woodwork tenon and tenon structure by hand. The next moment, the hand shakes gently, and everyone is stunned, pulling out the follower blade from the guide blade The shape is exactly the same, and the metal core is densely packed with cooling holes.

At the same time, Zhuang Jianye slowly said: "Let me answer first how our guide vanes solve the problem of insufficient structural strength and ductility of ceramic materials..."

Speaking and pointing to the metal core that he extracted most of: "Our method is very simple, that is, to add a set of metal bones to the ceramic material, which is somewhat similar to the honeycomb core in the honeycomb material commonly used in the aviation industry. The role of the ceramic blade shell support.

However, because of the characteristics of ceramic materials and the harsh working environment between the combustion chamber of the aero engine and the high-pressure turbine, a simple fixed honeycomb structure is not enough to reduce the impact of high-pressure gas turbulence, and it needs to offset the greater impact potential energy. According to our 2.5-generation core Take the 17MW power of the engine as an example, the temperature in front of the turbine reaches 1728K, which is 1454 degrees Celsius, and the impact force of the high-temperature heat flow in the combustion chamber reaches 9.05×10 6th power MPa.

Such a strong impact force cannot be supported by the general honeycomb structure. Therefore, we have added a metal wave spring on the outside of the metal core, so that when the outer ceramic blade is strongly impacted by the high temperature heat flow, the wave spring can reduce the internal The potential energy will eventually withstand the damage caused by the high-temperature jet to the overall blade under the support of the metal core. "

As Zhuang Jianye said, he pulled out the stack of metal sheets that were attached to the outer layer of the metal core like origami, and then stretched back and forth to show everyone present, and then said: "This is like ancient times. Like the heavy armor of the soldiers, ceramic materials are highly defensive armor, wave springs are muscles and soft tissues, and the innermost metal core is the supporting bones.

The effective coordination of the three can enable the soldiers to perform well. The same is true for our guide vanes. Thanks to the organic combination of three different components, our guide vanes have doubled their ability to withstand high temperatures and pressures. Together with the cooling airflow, it is also reduced by 25% compared to the previous second-generation core engine, thereby increasing the efficiency of the turbine's work..."

What Zhuang Jianye introduced was nothing but details. Several interested persons in charge of the aviation development plant listened more carefully. However, there was still a person in charge who asked inexplicably before Zhuang Jianye finished speaking: "Mr. Zhuang, according to what you just said. Said that the internal metal core and wave spring should be made of nickel-based alloy. I wonder if the requirements of this nickel-based alloy are high?"

"Not high!" Zhuang Jianye waved his hand and responded with a smile: "It's not high at all, just use the nickel-based alloy material on our turbojet 13 engine, which is the second-generation domestic nickel-based alloy, which is not used at all. What single crystal material, after all, the worst high temperature is blocked by ceramic materials, and the interior is naturally supported by many such good materials. Otherwise, what use is there for us to make this ceramic armor?

Isn’t it just to avoid the bottleneck in our own metal material metallurgy field, and to reduce costs as much as possible, so please don’t worry about this, as long as you have done the turbojet 13 matching, there are second-generation nickel-based alloys. With experience in processing and production, it is no problem to assist us in the production of metal cores and wave springs in Ascendas Group! "

After hearing this, the people in charge of the aviation development factory who were already quite interested felt that the heart in Dong's chest had begun to throb. This was no longer interested, but could not restrain the rhythm of his heartbeat.

Turbojet-13 is one of the few domestic aviation development projects that can be fully implemented. Many aviation manufacturers have participated more or less, and even some factories are turbojet-13 second-generation nickel-based alloy thermal components. The established production and processing unit of the company is quite knowledgeable in processing second-generation nickel-based alloys.

Therefore, I heard that the metal parts inside the guide vane that Zhuang Jianye is holding are so simple, why don't you want to try it?

It should be known that this is the core component of world-class aviation development ~ www.readwn.com~ Being able to participate in it is equivalent to competing with the advanced products of the world aviation development giants, let alone fill the domestic gaps, nor can we say The fact that the number of advanced patents obtained is simply the fact that they stand side by side with the world's aviation development giants is enough for these responsible people to make a big fuss in the year-end report.

And another manifestation of this kind of hype is the political achievements that make them dream of.

They pressed the Tengfei Group, grabbed projects, digged into the wall, and even did the disgusting thing of buying "domestic products" from Russia. Why? It's not for the word "political achievement".

Now, Zhuang Jianye puts such an easy task of brushing his political achievements in front of them. If this is not grasped, it is really tolerable or unbearable!

However, just when these people in charge began to think about how to get the metal core of the guide vane and the processing and production of the wave spring into their own factory, Zhuang Jianye's next sentence made the people in charge who just gave birth to this idea. A lot of crashing cold:

"By the way, I almost forgot. Don't use small Japanese equipment for processing this set of metal cores and wave springs. None of those broken gadgets can meet the accuracy requirements. All TMs are pit goods!"
