"The construction cost of these buildings cost 100 million marks?" Lu Hengsheng stood behind Liang Yuan and glanced around at the construction site, which was still huge.

As Liang Yuan tried his best to promote cross-industry vision at the top management of Yuanjia, the CEO of COMAC in Hamburg was qualified for the infrastructure materials conference, and the general framework and important nodes of the project were well known.

Meng Dawei, the first executor of the entire COMAC infrastructure project, quickly explained after hearing Lu Hengsheng say this: "If the engineering volume of these civil engineering projects is placed in China, the construction cost of 100 million yuan will be done for the third bureau of China Construction ...... most, but the third bureau has not obtained any construction certification in the Federal Republic of Germany for the time being, and can only face a Europe-wide bidding, and the price and construction period of Hachtief are the best ." ”

Seeing Meng Dawei's long speech, eager to report all the details, Liang Yuan waved his hand and said with a smile: "Hao Haotiev is the largest construction company in the Federal Republic of Germany, and the construction level can also rank among the top five in Europe, this offer is not much." ”

COMAC's wharf is located on the west bank of the Elbe River, with a large semicircular bay deeply recessed on the bank of the river, and the opposite side of the river bend is the main production plant of COMAC.

While walking and talking, Liang Yuan, Lu Hengsheng, Li Guowei and others bypassed the river bay and just turned the five-story R&D building, and the park road at the entrance of the main workshop behind the building was crowded with milky white MAN van heavy trucks.

Liang Yuan looked at it for a while, and only recognized the famous Klaus Maffei Company on the heavy truck compartment painted with the logos of major enterprises.

"The equipment is coming?" Liang Yuan turned his head and asked Meng Dawei.

Well, the water, electricity, lighting, and building interior decoration of the main production workshop have all been completed, and the basic processing equipment and aviation special processing equipment have begun to be installed in the factory. Meng Da nodded.

"Go over and see. Liang Yuan suddenly became excited.

Since the main product is an aircraft, COMAC's main production workshop is more like a large warehouse than a factory.

The overall painting of the COMAC factory was chosen by the two girls in a warm light beige, and the whole plant was roughly rectangular in structure. Just 25 meters high from the ground to the ceiling, the building is composed of hollow long-span steel structure, without any load-bearing façade inside the building, and nine stout high-strength alloy steel columns provide solid support for the 400-meter-long, 200-meter-wide all-steel roof.

The light blue steel dome was covered with bright yellow high-power sodium lamps, and the light yellow light shimmered on the turquoise dust-proof ground. Standing at the main gate of the 60-meter-wide and 18-meter-high workshop and looking at the other end of the workshop 400 meters away, the lonely emptiness with the industrial sense of cold and hard steel goes straight to the soul, making people have to bow down to the greatness of human science and technology.

"It's a sci-fi scene, and it can fit at least ten standard football fields. Liang Yuan said with a little satisfaction.

"CMB Aerospace's main building is a third larger than ours. ”

Li Guowei's eyes were also full of enthusiasm when he inspected the factory, how many years have passed? Finally, Chinese capital has stepped into the door of the pinnacle industry of human science and technology.

"Da Shao, Klaus Maffei's equipment engineer told me a few days ago that after the completion of COMAC's factory, the level of hardware equipment is more advanced than that of Claus Military Industry, which produced Leopard tanks for the West German Wehrmacht. Meng Dawei's posture stood straight.

"Except for Klaus Maffei, it seems that many equipment suppliers don't know each other. Liang Yuanyou looked around.

"Big Little. Mr. Meng is not right at all, whether it is general equipment or aviation special equipment, it is the first-class enterprises in West Germany that can provide products for commercial aviation. Li Guowei nodded while watching.

Meng Dawei took a step forward and pointed to the different areas of the workshop one by one: "Lathes from Grob, laser cutting machines from Trumpf, Schuler, a leading brand in the field of punching machines, multifunctional processing stations from Emag, high-precision grinding machines from Schleifring, ....... ”

COMAC built its factory in Hamburg, Germany. There is no chaos here such as the Batumi Committee, and at the request of Liang Yuan, a large amount of cash in hand is not asked about the price, but only seeks the best. In terms of equipment ordering, the top machinery and equipment suppliers in the Federal Republic of Germany are basically exhausted.

In addition to the common multi-axis linkage composite machining center in later generations, which is limited by the level of semiconductor technology, the general processing equipment ordered by COMAC at this time can be used until the new century without considering the problem of obsolescence.

"Mr. Li, these are the production equipment of CM100?" Lu Hengsheng asked.

"But that's not all. ”

Li Guowei smiled and continued: "Most of these are general-purpose basic equipment in the aviation industry, and many high-precision professional equipment are not available here. ”

"So much is the foundation?" Lu Hengsheng's tone was a little surprised.

"Multi-directional die forging machine, vacuum brazing, large wall plate shot peening machine, isothermal die forging, matrix multi-point vacuum gantry milling, three-axis gantry laser shallow milling and cutting machine...... There is still a lot of lack of cutting-edge large-scale equipment. ”

The types of large-scale equipment mentioned by Li Guowei are all proprietary equipment that is at the core of the aviation industry. Vacuum brazing, multi-directional die forging and isothermal die forging are often used in the structural fields such as aero engines and passenger aircraft main beams and landing gear, while equipment such as large-scale wall plate shot peening machine and matrix vacuum gantry milling are special equipment for processing the outer skin of large aircraft.

"In addition to vacuum brazing equipment, we don't have what Mr. Li said. Liang Yuan said with some feelings.

"The types of equipment that Mr. Li said are being updated in the production workshop of CMB Aerospace, although CMB Aerospace is not a sole proprietorship, it should be regarded as our equipment. Meng Dawei added.

However, Lu Hengsheng knew that Liang Yuan had an extremely close relationship with the military of the Republic, and understood where Liang Yuan's feelings came from.

For example, before the invention of the cool-sounding large, skin-mirror-milling. Matrix multi-point vacuum gantry milling and its supporting multi-axis gantry laser shallow milling and cutting machine are the best aircraft skin processing equipment on the planet.

If Liang Yuan can get this set of equipment back to China, then for the Republic fighter at this time, it will evolve from the shiny rural aluminum style of the Jian-6 to the matte matte matte petty bourgeois appearance such as the F16 overnight, and in the field of civil airliners, the shortcomings of the short life of the Republic aircraft can also be greatly alleviated.

"Da Shao, if the 50-seat small regional airliner project can be resurrected, the Federal Republic of Germany should not hinder us from purchasing those types of core processing equipment, right?" Lu Hengsheng asked.

"The problem is that there are several types of equipment, and the Germans don't count. Liang Yuan said with a wry smile.

Although the Federal Republic of Germany has achieved incomparable success in the field of general machine tools, it is far inferior to Britain and France in the research and development of professional equipment for the aviation industry, and the large die forging machine of more than 40,000 tons, which is very important in the field of aircraft industry, is currently owned only by the United States, France and the Soviet Union.

Similar matrix multi-point vacuum gantry milling and three-axis gantry laser shallow milling and cutting machine are the products of the French Dufy Industries, and only the enterprises of the Federal Republic of Germany have the competitiveness of large-scale wall plate shot peening complete sets of equipment.

It can be said that the reason why the Federal Government of the Federal Republic of Germany is so keen on the joint venture regional airliner project with the Republic is that, in addition to employment, the Federal Government intends to evolve Germany's advantages and strength in the field of general machine tools into a higher-level industry through substantial investment and demand.

Of course, the strength of the Germans in the field of electromechanical also provides a solid foundation for solving the problem of high-end aviation production equipment, the reason why the Germans are inferior to France in this regard is nothing more than the influence of the defeated country, in the fifties and sixties of the great development of jet aircraft, Germany in the field of aviation related researchers at all, this almost extinct industry-wide fault has been the hidden pain of the Germans after the reunification of the two Germanys.

In order to make up for the lame leg in aerodynamics, the merged Germany even spent tens of millions of dollars and the Americans to jointly develop the next generation of advanced fighter demonstrators that can deflect the tail nozzle.

The design principle of the airspeed tube was born in the early 17th century, and its practical application in airplanes can be traced back to the middle of the 19th century, at the end of the 20th century, when the great 21st century was about to begin, and the Americans, who dominated the world in aviation technology, came up with this reason in complete defiance of the intelligence of the Germans.

It can be said that the reason why the Typhoon fighter jointly developed by Europe was able to break through many obstacles and succeed in its development has a great deal to do with the fact that the Americans are full of bad water and do not do anything.

For the Republic, there has always been no shortage of theoretical research in the aviation industry, and the weak industrial base is the biggest constraint that limits the imagination of the Republic's aeronautical engineers, and this complementarity in the field of intelligence is also one of the reasons why Liang Yuan chose the Federal Republic of Germany to develop the next generation of advanced passenger aircraft.

Hearing Liang Yuan say this, Lu Hengsheng couldn't help but shake his head again and again when he thought back to what the Republic had just experienced.

"Every time I see Mr. Liu, Mr. Zhou, Mr. Sun, and their work briefings in West Germany, I am very headed, around the CM100 project equipment procurement and production standards, the British, French, Germans plus us, just enough to play mahjong, the relationship here is really complicated to the extreme. Lu Hengsheng said with a wry smile.

Lu Hengsheng, Li Guowei, and Meng Dawei accompanied Liang Yuan to visit the new factory of COMAC slowly, and Liu Wenyue and Zhou Yuanhang, who were described by Lu Hengsheng as big-headed, were sitting in the conference room of CMB Aerospace, slowly looking at the forehead of the negotiator in front of him, and his face was flushed.
