If it were before, Xiao Feng would not dare to give the generals on the other side.

But some time ago, he visited the industrial robots at Xinghuo Technology and had a detailed understanding of the performance of the robot.

As he now knows, this kind of tube is really a pediatrician for that industrial robot.

So he smiled slightly at the generals opposite: "This... I think it should be fine."

He said it lightly, but the generals on the other side felt like thunder in their ears when they heard it!

The general who asked the question just now even sat up straight and his expression became more serious.

"Mr. Xiao, what you said is true? This is a joke!"

In fact, whether it is J20, J15, or our Y20.

This aircraft engine has always been a problem that bothers us and is the most troublesome problem for us.

Forty years ago, we started to connect with the world with the country. In the first ten years, we gradually learned about the gap between us and the world.

For the next decade, we have been keeping our time and spending our constant depression and collapse.

At that time, the more we understood the world, the further we found that we were lagging behind the world.

At that time, let alone comparing with the United States and the United States, we could not compare with the Southern Dynasties of Japan.

At that time, even the air force on a certain island was not weaker than us.

Because we are still using J8, and others have already used F16.

So at that time, those people didn't take us seriously at all.

Later, until several frictions of about two thousand years, we were slapped in the face, but we could only knock down our front teeth and swallow them after we swallowed them.

From then on, we made up our minds to overcome all difficulties and catch up.

No one knows how we survived those thirty years?

In the ten years after that, we worked hard and sent out many personnel.

It is precisely the contribution and sacrifice of those overseas personnel that bring us a lot of valuable information.

It is precisely because of those valuable information that we have been catching up step by step since we lagged behind for decades.

It was only about ten years ago that we finally figured out where we were behind others?

That's right, in the first thirty years, we just knew that we were at least thirty years behind other people's aerospace engine technology, but why we were thirty years behind? In what respect, we were slandering and couldn't explain clearly.

It was not until almost ten years ago that we learned from the Japanese that the cost of aviation components was almost 50% from materials.

There is a huge gap between us and others in terms of materials, and it is the information we get from Japan that let us know.

It turns out that the American Aviation Engine has more than 50% of the components, and they use special metal materials such as titanium nickel cobalt and other alloy processes.

It was at that time that we realized why the turbofan blades on the rotor inside the aircraft engine were so powerful.

Not only is it a unique design concept and processing technology, but it also adds metal rhenium to it when the blades are smelted.

It is this rare metal that gives this turbofan blade super strong creep resistance.

After we got that information from Japan, we also produced an engine prototype according to the information from the Japanese.

In addition, alloy materials such as titanium nickel cobalt are also widely used in the engine.

Even the turbofan blades on the rotor are made of these materials.

However, an accident occurred during the installation test flight, and the aircraft engine entered the super-high speed working state.

I couldn't hold on for a few minutes and even had parts sprayed out of the sprayer port.

The most serious thing is that even the turbofan blades are broken, then the combustion behind them is broken, and finally sprayed out from the nozzle.

We even sacrificed several pilots because of this major accident like Aero Engine.

But after thinking about it, everyone still couldn't figure out what was going on?

Did we follow the Japanese manual?

It was not until later that a specialized personnel sent back information from the United States that everyone knew that the Americans also cheated the Japanese.

Although they can supply airplanes and aircraft to the Japanese unlimitedly.

He even taught the Japanese to disassemble and maintain.

But they will still be good at the Japanese in terms of aviation engine design, key components design, and production and production.

The materials and information about aircraft engines that the Japanese possessed were basically found by themselves after using US aircraft engines for decades.

But they didn't know that when the Americans were producing the turbofan blades on the aircraft engine rotor, they would add metal rhenium to it.

Because the working environment of this rotor turbofan blade is very special, it goes without saying that the high pressure is high, and it may have to work at an environment of thirty atmospheric pressures at the highest time.

It also needs to ensure a revolution of hundreds of thousands per minute, and the temperature inside the air compressor is very high at this time.

The maximum can be even more than 3,000 degrees. Those turbofan blades work in such high temperature and high pressure environments. It is impossible to determine the alloys of titanium nickel cobalt alone.

The alloys smelted together by these metal elements have extremely hard and resistant to stretching.

But the problem is that even if you work in such a high temperature environment for a long time, even such hard metals will have hot melting.

Especially when the aircraft enters supersonic cruise, the aircraft engine enters violent combustion mode, which even takes more than ten minutes.

At this time, the blades of the turbofan are prone to melting and creeping at high temperatures exceeding 3,000 degrees.

It means that melting and deformation begins to occur when the edge of the blade comes out. If the time is long, the blade may even break.

Once it reaches that point, the engine will be completely scrapped.

And the fighter jets that were rushing forward in the air suddenly lost their power, and would be done and turned into a pile of scrap iron.

After metal rhenium is added to the turbofan blades, the turbofan blades work in such a high-temperature and high-pressure environment, and there will be no high-temperature creep.

This greatly improves the life and reliability of aircraft engines.

After understanding these principles, we began to search for metal rhenium all over the world.

Unfortunately, we discovered that this rare metal has basically been monopolized by the United States, Russia, France and other three countries.

Especially the United States, it almost monopolizes the production and sales of rhenium in the world.

No matter how high we say it is, we can't buy it.

It was not until almost five years ago that we discovered a rhenium mine in a mountainous area of ​​the Qinling Mountains.

Although the annual output is limited, it basically solves the material problems of our aeroengine blades.

At that time, we also got a lot of experts from the Ukrainian Antonov Company, and basically mastered the production and processing technology of engine turbofan blades.

It happened to have brought a batch of machine tools from a neutral country in Western Europe at a high price, which made the breakthrough in the turbofan series engines.

However, although it was a breakthrough, the production capacity has not been increased.

The main reason is that it is limited by insufficient processing equipment.

For example, the metal pipes that the general showed Xiao Feng, are all old technicians in the factory, using special equipment.

The iron rods produced by these alloy materials are drilled out because such pipes cannot be welded at all.

Because the welded pipes can't withstand the ultra-high pressure during the aircraft engine work.

It is like drilling the gun barrel, using the turn head to drill out bit by bit on the iron rod, and then polish it.

Finally, you need to use an ultra-high power bending machine, so these pipes are bent according to the required shape.

Because these pipes are special metal alloy pipes, their performance is very outstanding, such as very hard and poor toughness.

Therefore, when bent, the scrap rate is also very high.

It is very likely that ten bends will be, and in the end, only two more are qualified. This is the main reason why our aeroengine manufacturing cost has always remained high.

This is just the bent part, and when drilling the pipe in front, the scrap rate is even more amazing.

It would be great if you could finally get one pipe that would drill into a qualified one.

Moreover, because these metal alloys are very hard in texture, it is also very costly to drill bits.

Previously, the military received a secret report from Yang Lei and learned that there was another very advanced industrial robot on Xinghuo Technology.

It is possible to drill various winding cavity on the iron ingot and use integrated molding technology to create a hydraulic valve.

To be honest, the expert who was aware of the technology at that time felt like a fantasy when he heard this information.

You should know that it is not difficult to drill holes on an aluminum alloy iron ingot that is thirty centimeters long, forty centimeters wide, and twenty centimeters high.

But isn't you kidding that you can drill out a cavity as complicated as a hydraulic valve on such a large iron ingot?

Even if aluminum alloy is not as hard as titanium alloy, it is also metal and very hard.

To drill out of a maze like an underground palace on such an iron ingot, those experts feel that their brains are a bit insufficient.

But later, Yang Lei sent a very short video image, but after watching this video, many experts were confused at that time.

After waking up, the news was reported immediately, and then the military equipment department held a series of discussions about this machine.

Then today's meeting came, and there were also face-to-face inquiries from the generals.

Now that Xiao Feng gave a positive answer, how can the generals remain calm?

"I'm certainly sure that our industrial robots produce such pipes, there is no problem."

"It can even be processed in one piece..."

Xiao Feng, who knew the strength of the robot, was very confident at this time, and the generals on the other side quickly turned red.
Chapter completed!
