Chapter 911

Yes, at the moment, credo's face is full of disbelief. Not only he, but also other executives of Embraer are shocked by the palm sized Y-shaped jet nozzle.

I can't help it. This kind of fuel nozzle is so amazing that they, senior people in aviation industry, are stunned for a long time. They can't see how it is made.

Generally, no matter what the shape and structure of the fuel nozzle are, the number of components is between 22 and 28. Although the materials of each component are different, they are basically made of titanium alloy or magnesium alloy light alloy.

So in the weight control can only be said to be passed, not excellent.

But the Y-shaped fuel nozzle Lin Guanghua gave them is not the same, not only the weight is lighter than the traditional fuel nozzle, but also the key is that the whole is integrated, so that there is no trace of assembling parts on the surface.

What does that mean?

Since childhood, Tengfei group has mastered an advanced new technology of Aeroengine Fuel nozzle.

Generally speaking, Tengfei group has carried out disruptive innovation in high-end precision manufacturing.

This may not be obvious to laymen, but crierdo and others are old birds who have been in the aviation industry for many years. It is the so-called "layman watching the crowd, expert watching the door".

Although it is difficult to manufacture aero-engine fuel nozzle without turbine blade, it is unimaginable to make more than 20 parts in an integrated way.

Among other things, the internal structure of the fuel nozzle is very unique, involving fuel control, pressure output and other components. If not, how can many giants not know the benefits of integration after studying for so many years? As a result, many times because of the complexity of simple, do more than 20 parts of the assembly goods?

It's not that I don't want to, but that I can't do it at all. Integrated manufacturing is good. The problem is how to give consideration to the internal structure?

It is such a problem that has plagued the giant for half a century that Tengfei group has not only solved, but also has a very high degree of maturity in terms of the products on hand. Not only the appearance is impeccable, but also the internal structure is extremely fine.

"This is one of the most important supporting products of the new generation aero-engine of our Tengfei group. We call it the laser additive integrated fuel nozzle. Of course, the scientific name is too tongue twister, so we give it a more appropriate name, which is called 3D printing nozzle..."

Looking at the shocking and different eyes of crierdo and others, and the desire to explore and study, Lin Guanghua began to introduce this 3D printing nozzle slowly with a knowing smile.

In fact, Lin Guanghua is right. The 3D printing nozzle is indeed an important component of the new generation aero-engine of Tengfei group, but it has some reservation. That is, the lightning-120 long endurance UAV using this 3D printing nozzle is in fact just a comprehensive test and verification platform for supporting technologies of the new generation aero-engine built by Tengfei group.

This is also no way, the acquisition of an aviation technology must do sufficient experimental verification in order to obtain sufficient supporting demonstration data.

Superpowers such as the United States and the Soviet Union are rich and powerful, and they can spread freely on the test machine. Obviously, China does not have such conditions.

When it comes to the entity of Tengfei group, it can't compare with monsters like the United States and the Soviet Union. The problem is that it's difficult to get accurate data by computer simulation only relying on wind tunnel test for some aviation demonstration, and the price of the usual test verification machine is not only expensive, but also not very practical.

Among other things, Tengfei Jitu built five "science fiction star" test and verification aircraft for airborne electronic equipment and telex control of the 10th project a few years ago, and then Then there's no more.

So far, this model is the one with the worst sales performance of Tengfei group. In addition to the overbearing style, it is a loss product.

If Tengfei group goes along this road of no return, the big family will have to go bankrupt sooner or later.

Therefore, under the careful consideration of Zhuang Jianye and others, Tengfei group has found a new way to build a test and verification system that attaches equal importance to unmanned and manned aircraft by taking the large-scale UAV platform as the main test and verification model and cooperating with the existing two "science fiction star" test and verification aircraft.

In recent years, the flight verification of many major projects of Tengfei group is basically completed by using ty-6 large UAV platform. If you need special structure, you can quickly refit it immediately. In a word, for Tengfei group, which started as a UAV, playing with UAVs is a light car familiar road.

Take the demonstration of advanced supporting parts of new generation aero-engine as an example. Tengfei group added many advanced parts of aero-engine including 3D printing fuel nozzle to a wd-48j high-power turboprop engine, and integrated them into ty-6 large UAV platform.

After nearly half a year's test and adjustment, the wd-48j high-power turboprop engine used in the test has become more and more mature, especially in terms of fuel saving, reaching a new height, thus increasing the endurance of ty-6 large UAV from the original 48 hours to 120 hours.Based on this, lightning-120 was born.

Of course, Lin Guanghua won't even tell us about the past of these lightning-120 mice. Otherwise, such a good test object Bah, it's made with all our strength. How can the customized products be sold at a high price?

So Lin Guanghua's focus is on the unique performance of 3D printing nozzle. What parts have been saved by 95%, what weight has been reduced by 84%, what fuel utilization has been increased by 55%, what comprehensive fuel consumption has been reduced by 43%, what overall performance has been improved by 27% and so on. It's almost impossible to say that this 3D fuel nozzle is a rare treasure in the sky and on the ground.

Listen, crierdo and others are stunned.

Fortunately, crierdo is not an ordinary person. Although he was almost confused by Lin Guanghua who opened the conversation, he still kept a clear mind. Relying on this clear mind, he firmly grasped the key point of Lin Guanghua's words. When Lin Guanghua became thirsty, he immediately asked, "Mr. Lin, what is the 3D printing device you just mentioned what? Does Tengfei group have finished products here? "

"Ah ~ ~ it's a special high-end aviation precision processing equipment that we spent 8 years to build. The model is nb-233!"

"I don't know if there is any possibility of transfer here?" Asked crildo cheekily.

"Of course, but..." Lin Guanghua nodded without hesitation, but he stopped in the middle of the conversation, which made Kerry a little worried: "is there anything inconvenient?"

Lin Guanghua hesitated, but still frowned and said: "no, the main reason is that the production cost of this product is too high. Let's use an inappropriate metaphor. If ordinary machines are ordinary goods, then our nb-233 is the top luxury in machines and luxury in luxury goods. The cost alone costs US $800 million, alas We can hardly afford to use it! "

Hearing this, crildo's eyes lit up and immediately asked, "can we have a look at this nb-233?"
