1487 Do You Know How We Lived Those 30 Years?

If it had been before, Xiao Feng really didn't dare to give assurances to the generals on the opposite side.

But since some time ago, he went to Xinghuo Technology to visit the industrial robot there, and got a detailed understanding of the robot's performance.

Based on his current understanding, this kind of pipe is really a child's play for that industrial robot.

So he smiled slightly at the generals on the opposite side: "This... I think there should be no problem."

He said it lightly, but the generals on the opposite side heard it like thunder!

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

"Mr. Xiao, is what you said true? This matter is no joke!"

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

This aviation hair has always been bothering us, the most troublesome problem for us.

Since 40 years ago, we opened our country and connected with the world. In the first ten years, we gradually realized the gap between us and the world.

For the next ten years, we have been hiding our strengths and biding our time, and spent them in constant frustration and collapse.

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

At that time, not to mention the comparison with the United States and Mao Xiong, but even the comparison with Japan's Nanchao country, we couldn't compare it.

At that time, even the air force of a certain island was no weaker than ours.

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

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

Later, until several frictions around two thousand years ago, we were beaten in the face by others, but we could only knock out our front teeth and swallow our blood.

Since then, we have made up our minds to pursue despite all difficulties.

No one knows, how did we survive those thirty years?

In the ten years since then, we have been working hard while sending many people.

It is also the contribution and sacrifice of those overseas personnel that have brought us a lot of valuable information.

It is precisely because of those precious materials that we have been behind for decades and caught up step by step.

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

That's right, in the first 30 years, we just know that we are at least 30 years behind other people's aviation technology, but why are we 30 years behind, and in what areas are we 30 years behind? Can't tell either.

It wasn't until almost ten years ago that we learned from the Japanese that almost 50% of the cost of the components of the original aviation engine came from materials.

And there is a huge gap between us and others in terms of materials, and it is the materials obtained from Japan that let us know.

It turns out that what's so special is that more than 50% of the parts of the aircraft in the United States are made of special metal materials made of several alloys such as titanium, nickel and cobalt.

And it was at that time that we knew that as for the turbofan blades on the rotor inside the aviation engine,

Why are Laomei's blades so powerful?

Not only because of their unique design concept and processing technology, but also because they added metal rhenium to the blades when they were smelted.

It is this rare metal that endows this turbofan blade with super creep resistance.

Originally, after obtaining the information from Japan, we also produced a prototype engine according to the Japanese information.

And on the engine, a large number of alloy materials such as titanium nickel cobalt are also used.

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

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

It collapsed within a few minutes, and even sprayed parts out of the nozzle.

The most serious, even the blades of the turbofan were broken, and then damaged the combustion chamber behind, and finally ejected from the nozzle.

We even sacrificed several pilots because of such a major accident.

But everyone thought it over and couldn't figure it out, what was going on?

We did it according to the Japanese manual?

It wasn't until later that special personnel sent back information from the United States that everyone knew that the Americans also tricked the Japanese.

Although they can supply the Japanese with unlimited supply of aircraft and aviation.

He even taught the Japanese how to disassemble and maintain.

But they will still keep the Japanese in the design of aviation development, the design of key components, and production.

The materials and information about aviation engines that the Japanese have mastered are basically what they have figured out after decades of using the aviation engines of the United States.

But they didn't know that when the Americans produced the turbofan blades on the rotors of aviation engines, they would add metal rhenium to them.

Because the working environment of this kind of rotor turbofan blade is very special, needless to say high pressure, it may have to work in an environment of 30 atmospheres at its highest.

Moreover, hundreds of thousands of revolutions per minute must be guaranteed, and at this time the temperature inside the air compressor is very high.

The maximum can even reach more than 3,000 degrees, and those turbofan blades can work in such a high-temperature and high-pressure environment, only relying on several alloys of titanium, nickel and cobalt.

The alloy smelted by combining these metal elements has the characteristics of being extremely hard and resistant to stretching and stretching.

But the problem is that in such a high-temperature environment, working for a long time, even such a hard metal will melt.

Especially when the aircraft enters supersonic cruise, the aviation engine enters the violent burning mode, which may even last for more than ten minutes.

At this time, the blades of the turbofan are prone to melt creep at a high temperature of more than 3,000 degrees.

It is at the edge of the blade that melting and deformation begin to occur. If the time is long, the blade may even break.

Once that point is reached, the engine is completely scrapped.

And if the fighter jets soaring in the air suddenly lose their power, they will be finished and turned into a pile of scrap metal.

After the metal rhenium is added to the turbofan blades, the turbofan blades will not suffer from high-temperature creep when they work in such a high-temperature and high-pressure environment.

This greatly improves the life and reliability of the aircraft engine.

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

It's a pity that we discovered at this time that this rare metal has basically been monopolized by the United States, Russia, France and other three countries.

The United States, in particular, has almost monopolized 80% of the production and sales of rhenium metal in the world.

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

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

Although the annual output is limited, it has basically solved the material problem of our aviation blades.

At that time, we also brought in many experts from the Antonov company in Ukraine, and basically mastered the production and processing technology of engine turbofan blades.

It just so happened that a batch of machine tools were bought at a high price from a neutral country in Western Europe, and this was the breakthrough of the turbofan series engine.

However, although it is a breakthrough, the production capacity has not been able to increase.

It is mainly limited by the lack of processing equipment.

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

It is drilled on the iron bars produced by these alloy materials, because such pipes cannot be welded at all.

Because the welded pipes simply cannot withstand the ultra-high pressure when the aircraft is working.

Just like drilling a gun barrel, use the turning head to drill out a little bit on the iron rod, and then polish it.

Finally, an ultra-high-power bending machine is used to bend these pipes according to the required shape.

And because these pipes are special metal alloy pipes, the performance is very outstanding, such as very hard, relatively poor toughness and so on.

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

It is very possible to bend ten pieces, and finally only two pieces are qualified. This is the main reason why the manufacturing cost of our aviation engine has been high.

This is just the bending part. As for the front drilling pipe, the scrap rate is even more astonishingly high.

Out of ten iron rods, if one can be drilled into a qualified pipe in the end, it is already very good.

And because these metal alloys are very hard, they also consume a lot of drill bits when drilling.

Before that, the military had received a secret report from Yang Lei, and learned that there was another very advanced industrial robot from Spark Technology.

It is actually possible to drill various winding cavities on the iron ingot, and use the one-piece molding technology to create a hydraulic valve.

To be honest, the knowledgeable technical experts at the time felt that this information was simply a fantasy.

One must know that it is not difficult to drill holes in an aluminum alloy iron ingot that is 30 centimeters long, 40 centimeters wide, and 20 centimeters high.

But you said that on such a large iron ingot, a cavity as complicated as a hydraulic valve is drilled, isn't this a joke?

Even though aluminum alloy is not as hard as titanium alloy, it is still a metal, and it is also very hard.

To drill a dungeon-like labyrinth on such iron ingots, those experts felt that their brains were not enough.

But later Yang Lei also sent a very short video image. After watching this video, many experts were dumbfounded.

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

Then there was today's meeting and the face-to-face inquiries of the generals.

Now that Xiao Feng gave an affirmative answer, how could the generals remain calm?

"Of course I can be sure that our industrial robots will have no problem producing such pipes."

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

Knowing the strength of that robot, Xiao Feng was very confident at this moment, and the faces of the generals on the opposite side immediately flushed.
