Schumann's gaffe immediately attracted the attention of the others, and they all cast puzzled glances.

Seeing this, Schumann immediately regretted it, and when he found out, he found out, what kind of excitement, Wayne and Morston have more attainments in management than technology, and the staff who came together are also stronger in aviation technology than in production and manufacturing capabilities.

Unlike him, in addition to a master's degree in aeronautical design, he also studied a master's degree in mechanical engineering, and because of this, Schumann not only knew the basic principles of aircraft, but also knew the process of its processing and manufacturing.

This is where Schumann has an advantage over the other two.

If you calmly encounter some unexpected good things in this helicopter assembly workshop, write them down quietly, and turn your head to Zhuang Jianye to buy them, which can be regarded as picking up a big leak.

As a result, Schumann's mentality was still arrogant, and he felt that Zhuang Jianye's claim was a bit exaggerated, coupled with the old-fashioned machine tools he had seen before, and the inherent experience 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, under the huge contrast, it was normal to exclaim in disbelief.

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

"Stress wave riveting, I think I've heard it somewhere!" Before Schumann could calm down, the keen Wayne immediately grasped the point, and Morston was not to be outdone, nodding and responding: "It seems that Grumman and Boeing in the United States have applied this technology." ”

As he spoke, Morston's eyes immediately widened, and he looked at the robotic arm in front of Schumann in disbelief, and then turned his head to Zhuang Jianye and asked, "Mr. Zhuang, could it be that you have introduced this technology from the United States?"

"Yes, Mr. Zhuang, as far as I know, the Americans are applying this technology to their most advanced fighters, bombers, and large airliners, and therefore the Americans are not open to their closest European allies, how did you get it?"

Equally puzzled is Vane, who, despite its U.S.-based headquarters in the United States, owns nearly half of its shares in European capital, and Vane 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 not much less than Schumann's, so Wayne simply made it clear that stress wave riveting is really high-end.

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

How high-end?

The F-14 fighter of the United States is the first aircraft to apply the stress wave riveting process, which also solves the connection problem of thin titanium alloy skin and high-strength titanium alloy stiffeners on the F-14 fighter.

Because the ordinary pressure riveting method and hammer riveting method are easy to damage the skin with a thickness of less than 0.5cm in the riveting process, resulting in micro cracks, which in turn affects the safety of the aircraft, because of this, the American Grumman Company, the contractor of the F-14 fighter at that time, innovated the riveting process and used stress wave riveting to solve the connection problem of thin titanium alloy skin and other stiffener materials in one fell swoop.

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

Boeing later introduced this technology and applied it to the riveting of the Boeing 747 wing in the 80s.

In the mid-to-late eighties, the models applied to this process were even more unbelievable, the B2 stealth bomber, the main contractor was Northrop, and Boeing was the subcontractor, due to the high standards of the U.S. military for the B2, Boeing didn't want to take out the stress wave riveting and use it in the riveting process of the central fuselage and wing of the rear section of the B2.

The Soviet Union is also widely used in stress wave riveting technology, which is mainly because of the development of the Soviet military aviation industry, so that the traditional riveting process can not meet its needs, so the Soviet Union has been spending a lot of effort in the basic process, and the stress wave riveting process is one of them.

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

Europe is much worse than the United States and the Soviet Union in this regard, because there is no need to engage in such high-end fighters and bombers militarily, so in the case of sufficient general riveting technology, Europeans do not feel how to stress wave riveting.

However, after their Airbus company has gained a firm foothold in the world's large passenger aircraft market with the A300 and A320 passenger aircraft, it is ready to enter the twin-engine and four-engine large wide-body passenger aircraft market, and then launch the research and development plan of the A330 and A340, ready to benchmark against Boeing 777, Boeing 747, DC-10, DC-11 and other models.

However, it was suddenly found that the original riveting process had unavoidable defects in titanium alloy, composite materials, ultra-thin gold skin, and mixed connection of various materials.

It is impossible to develop it from scratch, A330 and A340 have been launched, Airbus is eager to push these two types of aircraft to the market in the next second in order to seize the market, hammering Boeing and McDonnell Douglas, how can it be possible to endure the mind to let the aircraft and other equipment?

If it's too late to develop, you can only buy it, and the European Union can't even think about it, the reason is very simple, Lao Maozi's equipment highlights the sturdy and durable minimalism, so most of the stress wave riveting in the Soviet Union is manual, and the automatic ones are not nothing, but the top ones are outrageous with a single function.

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

So the United States can only be chosen.

The letter of intent was sent, and American aviation manufacturing giants such as Boeing and McDonnell Douglas looked at it, good guys, the old enemy wants to buy a hoe from the United States to dig up the ancestral grave of the United States, and this is still necessary?

It must be delayed, and if it can't be delayed, the price will be shouted, and the price is so high that even Airbus is confused.

There are Boeing and Airbus two big stirring sticks to the death, Airbus to introduce the United States stress wave riveting equipment can be imagined the degree of difficulty, the two sides began in 1988, talked for two whole years, stunned did not come up with a reason.

This is not a secret in the whole of Europe, and even regarded it as a shame in the eyes of some radical Europeans, who feel that it is a malicious suppression of the European aviation industry by the Americans relying on their technological superiority.

Therefore, at this time, whoever can come up with the available automatic stress wave riveting equipment and return to Europe will not only be able to make several times the profit, but also become a hero in the European aviation industry.

Proper fame and fortune.

Although Wayne and Morston are engaged in aviation maintenance, it does not prevent them from getting involved in other businesses, such as the agency and maintenance of professional aviation manufacturing equipment, which is also an important source of income for them.

So when they found out that the automatic riveting equipment in the Xiangzhou field applied the stress wave riveting process, the shrewd two immediately realized that the opportunity to make a lot of money had come.
