Take Off My Aviation Era

"This one……"

Hearing what Zhuang Jianye said, whether it was Abdullah or Mahmoud, the excitement of coming over to see what happened in the laser precision machining workshop more than ten minutes ago disappeared in an instant, even if his private life was exposed.

It felt as if I was finally about to see the goddess I had long wanted. After all, my sane brain couldn't beat the cerebellum full of worms. I hurriedly pushed the door and found out that the goddess is indeed a goddess, but this goddess is already seventy and eighty years old. The bright of the year.

So the worms retreated, and the clever IQ once again occupied the high ground, so each of them had a little bit of resentment in their eyes. I took off my pants, just show me this?

Invisible and bomb bay, just a plate welding equipment, how stealthy, and where is the bomb bay!

As for Aziz and other people in the industry, the corners of their mouths twitched, and among the uncertain eyes, an emotion called "being fooled" burst out undisguised.

In fact, not only these outsiders, but even the head of the headquarters who came with him, are secretly holding their foreheads, with black lines on their foreheads. He originally thought that Zhuang Jianye brought Abdullah and others to see the NB-2550DL automatic linear friction welding machine. Well, that is the top welding equipment in the world today.

The overall performance is equivalent to that of Pratt & Whitney's automatic linear friction welding machine. Thanks to this automatic linear friction welding machine, Pratt & Whitney will boldly equip the F-119 high-thrust turbofan engine in the F-22 battle. It adopts the whole blisk technology.

The focus is on the whole leaf disc technology, not the whole leaf disc technology.

That is to say, the F-119 low-pressure and high-pressure compressors with a total of more than ten stages completely adopt integral blisk technology, instead of using integral blisk technology like other aviation manufacturers, or the low-pressure compressor adopts integral blisk technology, and the high-pressure compressor adopts traditional mortise and tenon connection. Process; Or low-pressure machine uses traditional technology, high-pressure machine uses integral blisk technology.

This can minimize the risk.

But Pratt & Whitney didn't do that. Both high pressure and low pressure adopt integral blisk technology. In addition to Pratt & Whitney's confidence in materials, it is also very confident in its own manufacturing process.

Because of this, the F-119 high-thrust turbofan engine has a larger diameter than the previous generation F-110 series engine. At the same time, the number of parts is greatly reduced, and the total mass is also reduced by several percentage points. At the same time, the overhaul interval and use The service life has been improved qualitatively, and it can be regarded as an engine that does not break down.

Based on this, the headquarters and the development team of next-generation combat aircraft have listed Ascendas Group’s NB-2550DL automatic linear friction welding machine and NB-6600DL ultra-precision laser drilling machine as the key core manufacturing equipment for the next generation of high-thrust engines.

Since the NB-6600DL ultra-precision laser hole making machine has been seen by guests from the UAE and Algeria, it’s okay if the head of the headquarters wants to have a look at the NB-2550DL automatic linear friction welding machine. Anyway, it is not for sale. Urinary sex, you can't get pregnant at a glance, it's better than two local tyrants arguing for more than a dozen NB-66s.

What's more, Zhuang Jianye led them to look at the welding equipment, but he didn’t have any good intentions. You must know that Ascendas Group has upgraded several rounds over the years, and the welding equipment is the most eliminated. There are three warehouses covering an area of ​​4,000 square meters, and they are lazy to repair. Someone happened to come to pick up the repairs, and they didn’t pack it up quickly.

Therefore, the head of the headquarters did not stop him at the time. Instead, he let the flow go, and Ren Zhuang Jianye was tossing about it. As a result, he did not expect that Zhuang Jianye’s circling around was not the NB-2550DL automatic linear friction welding machine comparable to the United States. It is another NB-2330DL automatic welding machine.

This makes the head of the headquarters very confused. People in the UAE and Algeria have agreed to engage in the aerospace industry, but you, Zhuang Jianye, showed people to see aerospace manufacturing equipment.

That's all, before I kept saying that without the NB-2330DL automatic welding machine, there would be no stealth, and with it, there would be a bomb bay for a stealth fighter.

As a layman, you can fool Zhuang Jianye. The problem is that Abdullah and Mahmoud are not two people fighting this time, but they brought two groups of people, two groups of very professional aviation experts. They dare to fool. ? Is the welding equipment in those three warehouses really going to be bad for a lifetime?

It is no wonder that Abdullah and the head of the headquarters and others will be like this. The NB-2330DL automatic welding machine that Zhuang Jianye showed was nothing but a new welding process that has just emerged in recent years-friction stir welding.

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

At that time, Evans and Irwin in Europe bought relevant patents for the first time and gave them to Ascendas Group. Therefore, Ascendas Group became one of the few aerospace manufacturers in the world that mastered core technologies in this field.

It’s just that although this new welding process has many advantages and huge potential, it is a brand new thing after all. What is the specific application boundary and breadth of the world, including Ascendas Group, the world’s major giants and research units are exploring, so the current application The scope is not large, 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 regard, the Americans are the most widely used. The fuel tanks of their brand-new Delta heavy-duty launch vehicle almost all use friction stir welding as the connection method, and even the fuel tanks on the space shuttle use friction stir welding.

Thanks to Ascendas Group’s accumulation in this area, it also has a very wide range of applications in friction stir welding~www.readwn.com~ Especially in the aerospace field. Ascendas Group is responsible for the production of three types of Long 3, Long 4, and Long 5. The first-level liquid fuel storage tanks of the launch vehicle have all adopted friction stir welding, and the second-level fuel tanks are gradually replacing the previous gas shielded brazing with friction stir welding.

Civilian use lags slightly behind. In the military field, all the fuel storage tanks of the DF IV mid-range maintenance medium-range launch vehicle produced by Ascendas Group and the DF V long-range launch vehicle use friction stir welding.

As a result, the production schedule of the two launch vehicles has increased from the original 8 and 4 per year to 14 and 8.

This is due to the fact that the headquarters did not make full use of the Ascendas Group due to funding problems. If it runs at full power, other aspects will be left aside. But with regard to the fuel storage tank, Ascendas Group will be able to achieve that in the 1950s and 1960s. The classic remark of the leader of the surname He, the production of fuel storage tanks for launch vehicles is as simple as the production of sausages.

No way, the previous welding process, using the strength of the milk, the efficiency of welding the fuel storage tank of the launch vehicle is only 5mm\minute, while the friction stir welding is 12 meters\minute, 12 meters, which is quite At 12,000 mm, this is no longer an advantage to describe, it's just hanging.
