Schumann's gaffes immediately caught the attention of others, and cast doubtful glances.

Upon seeing this, Schumann immediately regretted it, and realized it by himself. What was the excitement. Wien and Moston are more skilled in management than technology, and the staff who came together are also more skilled in aviation technology than production. Manufacturing capacity.

Unlike him, in addition to a master's degree in aviation design, he also studied a master's degree in mechanics. Because of this, Schumann not only understands the basic principles of aircraft, but also knows the process of manufacturing.

This can be regarded as Schumann's bigger 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 your head to find Zhuang Jianye to buy them, which is a big leak.

As a result, Schumann's mentality is still arrogant. He feels that Zhuang Jianye's claims are a bit exaggerated. Coupled with the old-fashioned machine tools he saw before, combined with the inherent experience, this idea has deepened a lot.

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

The problem is that there are no problems in other places. At this moment in this workshop...

"Stress wave riveting? I seem to have heard it somewhere!" Before Schumann's thoughts calmed down, the keen Wien immediately grasped the point. Moston was not to be outdone, and nodded in response: "It looks like an American style. Ruman and Boeing have applied this technology."

As he said, Moston's eyes widened immediately, and he looked at the robotic arm in front of Schumann in disbelief, then tilted his head and asked Zhuang Jianye: "Mr. Zhuang, is it possible that you imported this technology from the United States? "

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

Also wondering is Wien. Although Wolff Aviation Maintenance is headquartered in the United States, nearly half of its shares are in European capital. Wien himself is not an orthodox American, but an Irishman.

Because of this, when he learned about the basic situation of stress wave riveting from his staff, his interest was not much less than that of Schumann, so Wien simply pointed out the words directly. Stress wave riveting is really high-end.

In fact, it is true. Schumann and Wien are right to say that stress wave riveting, as a subversive riveting process, is really not an ordinary high-end.

How high-end is it?

The American F-14 fighter is the first aircraft to apply the stress wave riveting process, and therefore solves the problem of the connection between the thin titanium alloy skin and the high-strength titanium alloy ribs on the F-14 fighter.

Because the ordinary pressure riveting method and hammering riveting method can easily cause damage to the skin with a thickness of less than 0.5cm during the riveting process, causing micro-cracks, which will affect the safety of the aircraft. Because of this, the F-14 fighter jets at that time The contractor, Grumman, USA, innovated the riveting process and adopted stress wave riveting, which solved the connection problem between the thin titanium alloy skin and other reinforcing rib materials in one fell swoop.

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

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

In the mid-to-late 1980s, the models used in this process were even more remarkable. The B2 stealth bomber, the main contractor was Northrop, and Boeing was the sub-contractor. Because of the high standards of the US military for B2, Boeing thought I didn't want to take out the stress wave riveting, and used the riveting process of the B2's rear central fuselage and wings.

The Soviet Union has also widely used stress wave riveting technology. This is mainly because the development of the Soviet military and aviation industry has made the traditional riveting process unable to meet its needs. Therefore, the Soviet Union has been investing heavily in basic technology, and the stress wave riveting process is convenient. Is one of them.

It is mainly used in the production of Tu-160 strategic bombers, Tu-22M bombers and MiG-31 fighters.

In this respect, Europe is far worse than the United States and the Soviet Union. Since there is no need for such high-end fighters and bombers in the military, Europeans do not think of stress wave riveting when the general riveting process is sufficient.

However, after their Airbus has established a firm foothold in the world's large passenger aircraft market with its A300 and A320 passenger aircraft, it is ready to enter the double-engine and four-engine large wide-body passenger aircraft market, and then launch the A330 and A340 R&D plans. When benchmarking Boeing 777, Boeing 747, DC-10, DC-11 and other models.

Suddenly, it was discovered that the original riveting process had inevitable defects in titanium alloys, composite materials, ultra-thin gold skins, and mixed connections of multiple materials. It was then discovered that stress wave riveting is not ordinary.

It is impossible to develop from scratch. The A330 and A340 have been launched. In order to seize the market, Airbus can’t wait to launch these two aircraft on the market in the next second, blasting Boeing and McDonnell Douglas. ?

If you don’t have time to develop it, you can only buy it. The European Union of the Soviet Union didn’t even think about it. The reason is very simple. Lao Maozi’s equipment highlights strong and durable minimalism, so most of the stress wave riveting in the Soviet Union is manual and automatic No, but all of them are horrible with a single function.

This is unacceptable for Airbus who wants to improve efficiency and reduce labor costs. (The labor cost in Europe is very high.)

So we can only choose the United States.

After the letter of intent was sent, the American aviation manufacturing giants such as Boeing and McDonnell Douglas took a look. Good guys, the old adversary wanted to buy an American **** to plan the American ancestral grave.

It must be procrastinated. If it is not procrastinated, the price will be advertised. It is best if the price is so high that even Airbus is damned.

Boeing and Airbus, the two big dung sticks, were mixed together. You can imagine how difficult it was for Airbus to introduce American stress wave riveting equipment~www.readwn.com~ The two sides started talking about two things in 1988. In the year, I didn't talk about why.

This matter is not a secret in the whole of Europe, and even regarded as a shame in the eyes of some radical Europeans, thinking that this is the malicious suppression of the European aviation industry by the Americans relying on their own technological advantages.

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

Proper fame and fortune.

Although Wien and Moston are engaged in aviation maintenance, it does not prevent them from getting involved in other businesses. For example, the agency and maintenance of professional aviation manufacturing equipment are also important sources of income for them.

So when they discovered that the automatic riveting equipment in the Xiangzhou field used stress wave riveting technology, the shrewd two immediately realized that there was an opportunity to make big money.
