Take Off My Aviation Era

If you see the wide-chord titanium alloy fan blades with forward and backward profiles like the scimitar of Rolls-Royce's "Trent" series turbofan engine, Djokovic is excited like a little otaku. There is nothing more to add.

Djokovic, who saw the "Z"-shaped structure inside, was completely excited to explode while riding a great ocean horse.

He really almost rolled his eyes and went directly to the Soviet sages.

It took a long time before I finally returned to the world, and then I didn’t care about taking a breath, and then I was steady for a while, then pointed to the "Z" structure in the model and asked urgently: "How did you make this structure? ?"

As soon as these words were spoken, I was worried that Djokovic had some shortcomings, those executives and experts in the Russian aviation industry turned their hopeful eyes on Liu Cong.

That's right, how did the Z-shaped structure arranged in the internal cavity of Ascendas Group make it?

We must know that the Soviet Union and later Russia have been studying this area for seven or eight years, but there has been no progress at all. Looking at the world, only the United Kingdom and the United States can really make this structure. semicolon.

No way, the titanium alloy "Z" structure as the support inside is not a traditional honeycomb structure, but a hollow-like truss beam structure, which is similar to the beams in a traditional house, with a lot of hollows in the middle of the bars.

In popular words, it is to use a titanium alloy hollow beam as thin as a hairline to support two outer blades of titanium alloy.

The principle is similar to the honeycomb sandwich structure of the previous generation, but the manufacturing is quite different.

After all, the honeycomb structure is a whole, and the corresponding overall plasticity is sufficient as required. As for the connection method, high-grade vacuum brazing or electron beam welding can be used.

Overall it is not complicated.

However, this method will not be able to play with the "Z"-shaped structure. First, this structure is not a whole. Secondly, the titanium alloy wire used to support the blade is extremely fine and cannot withstand any welding method. The coming high temperature burns.

If not, based on the Soviet Union's profound knowledge in welding technology at that time, the "Z"-shaped structure would have been solved long ago. Why wait until the disintegration did not understand what was going on?

Therefore, not only does Djokovic want to know this problem, but also other Russian executives and experts.

Although the current Liu Cong is no longer the half-hearted electrician when he was in the 23rd branch of the factory, he is essentially the honest guy who personally invited Zhuang Jianye to visit his home.

Seeing Djokovic's excitement, he almost went crazy...Bah~~ He almost went to see the sages. Liu Cong felt a little bit unbearable, so he weighed it up and said, "Uh... our fan The zigzag structure inside the blade is made using a method called super forming-diffusion bonding process."

"Super molding-diffusion bonding process?" Djokovic heard the words, his eyes narrowed unconsciously.

Liu Cong nodded without hesitation: "That's right, it's super molding-diffusion bonding process..."

Having said that, Liu Cong introduced the high-precision manufacturing process of Ascendas Group.

It turns out that Ascendas Group had mastered this technology as early as three years ago, but it did not apply it to the manufacture of turbofan engine fan blades, but applied it to an anti-ship missile.

Because the missile uses the WD-16P small turbojet engine produced by Ascendas Group to replace the original rocket engine, the overall aerodynamic layout of the missile has to be changed. However, in order to save money, the Navy requires the new anti-ship missile to use the old model. The launch device and storage device.

This requires that the overall size of the new anti-ship missile cannot exceed the old model too much, especially the diameter of the missile body must be determined in accordance with the upper limit of the Navy's existing launchers and storage devices.

This can hardly damage the chief designer in charge of the new anti-ship missile, because the turbojet-powered anti-ship missile is different from the previous rocket thrust of the old model. It needs ambient air to support combustion, so there must be air injection on the missile body. The air inlet.

According to the traditional design idea, a rectangular bulge will be set under the missile as the inlet of the air inlet for the turbojet engine to work normally.

The problem is that in this way, the diameter of the missile will greatly exceed the upper limit of the Navy’s existing launchers and storage devices, and will not meet the Navy’s requirements.

Changing to a retractable inlet is technically feasible, but the cost has soared rapidly, far exceeding the budget standard set by the Navy.

In desperation, the commander-in-chief of the new anti-ship missile simply copied the inlet layout of the US Harpoon anti-ship missile and designed a titanium alloy inlet with double-sided internal pipes.

In this way, the air inlet and the projectile body are almost flat, but the opening edge is slightly higher than the projectile body. This way, the efficiency of the turbojet engine can be maximized under the condition of meeting the requirements of the navy, and the maximum range of the new anti-ship missile can reach 150. Kilometers.

However, the design is very perfect, but in practice, it allows the development team to squeeze the hair.

The titanium alloy inlet of the double-sided inner pipe is good, but the key is that it is not easy to make it. First, control the weight. It should not be too heavy, otherwise it will cause the center of gravity of the entire missile to shift back, causing the missile to fire. Go and become a large diamond sky monkey.

Secondly, the structural strength must be good, able to withstand at least a large overload impact.

Finally, it has strong corrosion resistance. After all, it is naval equipment and cannot be too delicate in the high-salt and high-humidity marine environment.

In this way, the design team referred to the American Harpoon and proposed an integrated molding plan.

But the problem is that throughout the world, the only country that can make a "harpoon" that integrates the air inlet and the missile body is the United States, and the rest include France. The anti-ship missiles equipped with turbojet engines have One is counted as one, and there is no air inlet that does not protrude outside the projectile.

There is nothing more than one reason, that is, other countries do not have the cutting-edge manufacturing technology of the United States, and even if they can design it, they can’t make it.

In the face of this situation, the new anti-ship missile development team at that time said that it was not desperate. It was a fake. It was just that the dead horse was used as a living horse doctor to run around in various domestic manufacturers to see if they could find the so-called miracle.

As a result, this search really came from the supplier of anti-ship missile engines, where did the Ascendas Group find it.

In the supporting project of No. 10 project that Ascendas Group participated in at that time, the supporting production products of vertical tail wing beam and No. 3, 12, 27 and 28 reinforced ribs were just beaten by the chief engineer of No. 10 project. come back.

The reason is only one sentence: the technology is too advanced to meet the domestic mass production requirements.

At that time, the MMP mentality in Zhuang Jianye's mind was not to be mentioned. You must know that for these components, Ascendas Group almost put all the advanced technology of carbon fiber and aramid fiber on the bottom of the pressure box, but finally got such a comment. It will not feel good.

But the problem is that it’s uncomfortable and there is nothing to do. Military equipment, especially the main battle military equipment of the Air Force in the future, must always have a balance between advancement and mass production~www.readwn.com~ Otherwise, once the battlefront is opened, it will need to be large. Large-scale production, it turns out that those high-end materials are not available, so don't you have to be dumbfounded?

So the chief teacher's request was reasonable, so Zhuang Jianye gritted his teeth.

However, before Zhuang Jianye adjusted it, the new technical indicators of the No. 10 engineering chief once again made Zhuang Jianye violent, even if it was required to meet mass production, the new product standards should maintain the combined performance indicators of carbon fiber and aramid fiber. 85% of the total.

Use materials that can be mass-produced to reach 85% of the top high-end aviation materials, and more!

Is this a man-made airplane? It's just forcing people to hit the wall with their heads!

So after receiving this new technical standard, Zhuang Jianye carried a bottle of Erguotou on the roof of the Tengfei Group building, poured half a bottle frantically, and cursed in the direction of the Eastern Sichuan Plain for more than two hours. Go downstairs in a good mood.

Then...then the super-sho molding-diffusion bonding process was forced out under the weight of the chief engineer of the No. 10 project.
