Chapter 1055

"This..."

After listening to Zhuang Jianye's words, both Abdullah and Mahmoud's excitement at the laser precision processing workshop more than ten minutes ago, even if he exposed his private life, he couldn't wait to see it.

It felt as if we were finally going to see the goddess we had long cherished. After all, the rational brain couldn't fight the cerebellum full of sperm. We hurriedly pushed the door and found that the goddess was indeed a goddess, but the goddess was already seventy years old and eighty years old, and no longer as beautiful as before.

So the sperm retreated, and the intelligent intelligence once again occupied the high ground, so the eyes of each one were slightly resentful. I took off my pants, so I showed this to me?

Also stealth, also bomb cabin, on a plate welding equipment, how stealth, and where the bomb cabin!

As for Aziz and other people in the industry, their mouths are straight. In their uncertain eyes, there is a kind of emotion called "being fooled".

In fact, not only these outsiders, but also the head of the headquarters who came with them were secretly supporting their foreheads. He thought that Zhuang Jianye had brought Abdullah and others to see the nb-2550dl automatic linear friction welding machine, which is the top welding equipment in the world today.

Its comprehensive performance is comparable to that of Pratt & Whitney's automatic linear friction welding machine. Thanks to this automatic linear friction welding machine, Pratt & Whitney boldly adopts the full blisk technology on the f-119 high thrust turbofan engine equipped with F-22 combat equipment.

The key point is blisk technology, not blisk technology.

That is to say, the f-119 low-pressure and high-pressure compressor with a total of more than ten stages adopts blisk technology, not the same as other aeroengine manufacturers, or the low-pressure compressor adopts blisk technology and the high-pressure compressor adopts traditional mortise and tenon connection technology, or the low-pressure compressor adopts traditional technology and the high-pressure compressor adopts blisk Technology.

This will minimize the risk.

However, Pratt & Whitney did not do so. Regardless of high pressure and low pressure, they all adopt blisk technology. Apart from Pratt & Whitney's confidence in materials, they are also very confident in their own manufacturing process.

Because of this, while the diameter of f-119 high thrust turbofan engine is larger than that of the previous generation f-110 series engine, the number of spare parts is greatly reduced, and the total mass is also reduced by several percentage points. At the same time, the overhaul interval and service life have been qualitatively improved, which can be said to be an unbreakable engine.

Based on this, the headquarters and the development team of the next generation of combat aircraft have listed nb-2550dl automatic linear friction welding machine and nb-6600dl ultra precision laser drilling machine of Tengfei group as the key manufacturing equipment of the next generation of high thrust engine.

Now that the nb-6600dl ultra precision laser drilling machine has been shown to the guests of UAE and Algeria, it's OK for the head of the headquarters to come to nb-2550dl automatic linear friction welding machine for a look. Anyway, they are not for sale. It's better than two local tyrants quarreling over more than ten nb-66 to make their brains ache.

What's more, Zhuang Jianye didn't show them any good intentions when he led them to see the welding equipment. In recent years, Tengfei group has been upgraded several times, and the welding equipment has been eliminated most. The warehouse covering an area of 4000 square meters is full of three, and they are lazy to repair it. Someone just came to take over the plate, and they don't need to pack it quickly.

So at that time, the head of the headquarters didn't stop him. Instead, he let it be. As a result, he didn't expect that the nb-2550dl automatic linear friction welding machine, which could be compared with the United States, was another nb-2330dl automatic welding machine.

This makes the head of the headquarters very difficult to understand. The UAE and Algeria say they want to develop the aviation industry, but Zhuang Jianye takes people to see the aerospace manufacturing equipment.

That's all. Before, I kept saying that there would be no stealth without nb-2330dl automatic welding machine. With it, there would be the bomb cabin of stealth fighter.

If you're a layman, Zhuang Jianye can fool you. The problem is that this time, Abdullah and Mahmoud are not fighting. They are bringing two groups of people, two groups of very professional aviation experts. How dare you fool them? Is the welding equipment in those three warehouses really ready to rot for a lifetime?

It's no wonder that Abdallah and the head of the headquarters will be like this. The original nb-2330dl automatic welding machine that Zhuang Jianye took people to see is nothing else. It's a new welding process just emerging in recent years friction stir welding.

It was invented by British Welding Research Institute in 1991, and then followed up by many countries.

Evans and Owen, who were in Europe at that time, bought the relevant patents for the first time and gave them to Tengfei group. Therefore, Tengfei group became one of the few Aerospace Manufacturers in the world who mastered the core technology in this field.

However, although this new welding process has many advantages and great potential, it is a brand-new thing after all. The world's major giants and research institutes, including Tengfei group, are exploring the specific application boundary and scope. Therefore, the current application scope is not large and is only limited to the aerospace field.

For example, the special aluminum alloy fuel storage tank inside the long-range launch vehicle is welded by friction stir welding, and the flap seal of the fuel storage tank is also welded by friction stir welding.In this respect, Americans are the most widely used. Almost all the fuel tanks of their new delta heavy carrier rocket are connected by friction stir welding, and even the fuel tanks on the space shuttle are also connected by friction stir welding.

Thanks to the accumulation of Tengfei group in this field, it is also widely used in friction stir welding, especially in the aerospace field. At present, the primary liquid fuel storage tanks of Chang 3, Chang 4 and Chang 5 launch vehicles produced by Tengfei group have all adopted friction stir welding, and the secondary fuel tanks are gradually using friction stir welding to replace the previous gas Protective brazing.

In the military field, the DF IV medium range launch vehicle and the fuel storage tank of the DF V long-range launch vehicle produced by Tengfei group all adopt friction stir welding.

Thus, the production progress of the two launch vehicles has been increased from 8 and 4 each year to 14 and 8 each year.

This is also the result of the headquarters' lack of funds, which makes Tengfei group not fully start up. If it is fully powered, other aspects should be ignored. However, as far as fuel storage tanks are concerned, Tengfei group can realize the classic saying of the Soviet Union leader in the 1950s and 1960s, that the production of fuel storage tanks for launch vehicles is as simple as the production of sausages.

There's no way. In the past, the welding process has made great efforts. The efficiency of welding the fuel storage tank of launch vehicle is only 5 mm min, while the efficiency of friction stir welding is 12 m min, 12 m, which is equivalent to 12000 mm. This is no longer an advantage. It's just a sling.
