Chapter 650

Schumann's behavior immediately attracted other people's attention and cast puzzled eyes.

Seeing this, Schumann immediately regretted it. He discovered it by himself. What a thrill! Wayne and Moston are more accomplished in management than in technology. The staff who came together are also more accomplished in aviation technology than in manufacturing.

Unlike him, in addition to his master's degree in aviation design, he has also studied mechanical engineering. Because of this, Schumann is not only familiar with the basic principles of aircraft, but also has a better understanding of its manufacturing process.

This is Schumann's advantage over the other two.

If you come across some unexpected good things in this helicopter assembly workshop calmly, quietly write them down and turn to Zhuang Jianye to buy them, it's a big leak.

As a result, Schumann's attitude is still arrogant. He thinks that Zhuang Jianye's claim is exaggerated. In addition to the old machine tools he saw before, his inherent experience has deepened this idea a lot.

Because of this, when he found that the mechanical arm imported from Germany was equipped with stress wave riveting equipment, his incredible exclamation was normal under the huge contrast.

The problem is that there is no problem anywhere else, in this workshop at this moment

"Stress wave riveting? I seem to have heard it somewhere Before Schumann's thoughts calmed down, keen Wayne immediately grasped the key point, and Moston was not willing to be outdone. He nodded and responded: "it seems that Gruman and Boeing in the United States have applied this technology."

With that, Moston's eyes immediately widened. He looked at Schumann's mechanical arm in front of him in disbelief. Then he turned to Zhuang Jianye and asked, "Mr. Zhuang, did you introduce this technology from the United States?"

"Yes, Mr. Zhuang. As far as I know, the Americans have applied this technology to their most advanced fighter planes, bombers and airliners, so the Americans are not open to their closest European allies. How did you get it?"

Similarly, Wayne is puzzled. Although the headquarters of wolf aviation maintenance company is located in the United States, nearly half of its shares are European capital, and Wayne himself is not an orthodox American, but an Irishman.

Because of this, when he learned the basic situation of stress wave riveting from his staff, his interest was no less than Schumann's, so Wien simply pointed out that stress wave riveting is really high-end.

In fact, it is true. What Schumann and Wayne said is true. Stress wave riveting, as a subversive riveting process, is really not an ordinary high-end.

How high-end is it?

The F-14 fighter of the United States is the first one to apply the stress wave riveting technology, which solves the connection problem between the thin titanium alloy skin and the high-strength titanium alloy stiffener on the F-14 fighter.

Because the common riveting method, hammer riveting method is very easy to cause damage to the skin less than 0.5cm in thickness in the riveting process, resulting in micro cracks, thus affecting the safety of the aircraft. Just because of this, the then F-14 fighter contractor gluman company of the United States innovated the riveting process, using stress wave riveting, solved the problem of thin titanium alloy skin and other stiffeners at one stroke The connection problem of material.

(so the F-14 fighter is not only a legend of aircraft, but also a legend of aviation manufacturing.)

Later, Boeing introduced this technology and applied it to the riveting of Boeing 747 wings in the 1980s.

By the middle and late 1980s, the aircraft model used in this process was even more extraordinary. The main contractor of B2 stealth bomber was Northrop, and Boeing was the sub contractor. Due to the high standard of B2 by the US military, Boeing took out the stress wave riveting without thinking and applied it to the riveting process of B2's rear central fuselage and wing.

The Soviet Union is also widely used in the stress wave riveting technology. This is mainly because the development of the Soviet military aviation industry makes the traditional riveting technology unable to meet its needs. Therefore, the Soviet Union has been making great efforts to invest in the basic technology, and the stress wave riveting technology is one of them.

It is mainly used in the production of Tu-160 strategic bomber, tu-22m bomber and MiG-31 fighter.

In this respect, Europe is quite different from the United States and the Soviet Union. Because there is no need to engage in such high-end fighters and bombers in the military, when the general riveting process is sufficient, Europeans do not think about stress wave riveting.

However, when their airbus company gets a firm foothold in the world's large aircraft market with A300 and A320, it is ready to march into the twin engine and four engine wide body aircraft market, and then launch the R & D plan of A330 and A340, and prepare to benchmark Boeing 777, Boeing 747, DC-10, dc-11, etc.

But suddenly found that the original riveting process in titanium alloy, composite materials, ultra-thin gold skin, a variety of materials mixed connection and other aspects of unavoidable defects, then found that the stress wave riveting is not the general trend.

It's impossible to develop from scratch. The A330 and A340 have already been launched. In order to seize the market, Airbus is eager to push these two types of aircraft to the market in the next second, hammering Boeing and McDonnell Douglas. How can it bear to let the aircraft and other equipment go?The reason is very simple. Lao maozi's equipment highlights the strong and durable minimalism. Therefore, most of the stress wave riveting in the Soviet Union is manual, not automatic. However, the top one has a single function, which is appalling.

This is unacceptable to Airbus, which wants to improve efficiency and reduce labor costs. (labor costs in Europe are very high.)

So we have to choose the United States.

After the letter of intent was sent, Boeing, McDonnell Douglas and other American aviation giants saw that the old rivals wanted to buy American hoes to dig the ancestral grave of the United States. How could this be?

We have to delay. If we can't wait, we'd better ask for a price. It's better that the price is so high that even Airbus can't understand.

Boeing and Airbus are two big troublemakers. It's hard to imagine how hard Airbus is to introduce stress wave riveting equipment from the United States. The two sides have been talking for two years since 1988, but they haven't come up with a reason.

This is not a secret in the whole of Europe, and even in the eyes of some radical Europeans, it has even been regarded as a disgrace. They think that this is a malicious suppression of European aviation industry by Americans relying on their own technological advantages.

Therefore, if anyone can take out the available automatic stress wave riveting equipment and return to Europe at this time, he will not only make several times of profits, but also become a hero in the European aviation industry.

Good fame and good fortune.

Although Wayne and Moston are engaged in aviation maintenance, it does not prevent them from getting involved in other businesses. For example, professional aviation manufacturing equipment agency and maintenance business are also their important source of income.

So when they found out that the automatic riveting equipment in Xiangzhou field used stress wave riveting technology, the smart ghost like two immediately realized that the opportunity to make a lot of money came.
