Since the two sides want to cooperate, and AVIC Southwest is still involved in the cooperation as a project technology investor, then of course, it is necessary to show the visiting team of the German MM company the strong technical strength of AVIC Southwest, and the closest place to show the strength of Guiyang City, the headquarters of AVIC Southwest, is naturally the titanium alloy processing base that is also located in the aviation industrial park.

At this time, the titanium alloy processing base has been expanded many times, seven years ago from the Soviet Union to get the titanium alloy compressor blade production technology, at that time it was already awesome, but with the southwest of China Aviation or the whole republic of titanium alloy processing parts requirements are getting higher and higher, the middle has experienced a major technological upgrade and several times of technical improvement.

Of course, this technological upgrade has a lot to do with the collapse of the Soviet Union, at least the entire titanium alloy processing base relied on the four years before the collapse of the Soviet Union, and undertook a large number of titanium alloy processing projects at home and abroad, and the southwest science and industry era at that time was favored by good national policies, but let the titanium alloy processing base accumulate a lot of original capital, so that when the Soviet Union collapsed, it also brought a large number of processing technology and equipment, talents, etc. from all over the Soviet Union.

"What you see now is the largest titanium alloy processing base in the southwest of our AVIC and even the entire republic, which undertakes almost 80% of the titanium alloy processing and manufacturing tasks in the republic. However, who of you has ever seen this thing, this is definitely the part that can best prove the technical level of our AVIC Southwest in the field of titanium alloy processing. ”

Following Yang Hui's introduction, a whole circle of people has been enclosed in the process and product showroom of the processing base, and the compressor blades in the floor-to-ceiling glass display cabinets around the room, as well as conventional small parts, have attracted a few people.

The red isolation belt tells everyone that the things placed in the middle are definitely not ordinary colors, just looking at the cold metal surface, as well as the huge size of the workpiece, of course, the metal surface has been completely unclear cutting route, which also shows that the processing of the parts is either a one-time no margin forging in place, or super-finishing milling.

After all, these are all veteran drivers who have been in the aviation industry for many years, although MM has no experience in manufacturing large aircraft, but they have never eaten pork, they have always seen pigs run, so after a slight pause, someone immediately saw it.

"That's right, this is a large transport aircraft titanium alloy structural parts, look at the size to know that it is definitely a wide-body passenger aircraft can be used, then now your company's processing and manufacturing capacity has indeed reached a certain level, AVIC Southwest can make such structural parts, we are looking for the right partner this time."

The old German engineer's hair was already a little gray, but Yang Hui was a little puzzled, European countries that have always paid attention to human rights in recent years also need to squeeze the surplus value of the elderly?

Of course, the above is just a joke, really to say, the old re-employment of this situation is very common no matter where it is, some experienced and healthy old engineers, in the aviation industry such precision machining manufacturing industry is 50% chance to be re-employed, unless the company is indeed already difficult to protect itself and another matter.

"This is the titanium alloy load-bearing member specially manufactured by our company for the MD-11 passenger aircraft, not only the manufacture of the load-bearing member made of this titanium alloy material, but also other types. The Modu Aircraft Factory under AVIC Northeast Company of the Republic of China and McDonnell Douglas Company cooperate in the production of MD-11 passenger aircraft, so the fuselage partition of the MD-11 passenger aircraft with a diameter of 5.8 meters is also forged by the newly built 80,000-ton die forging hydraulic press of AVIC Southwest, so our technical strength of AVIC Southwest can be completely trusted. ”

Yang Hui's words are not false at all, now the Modu Aircraft Factory has begun to assemble the MD-11 passenger aircraft, it is said that the country has been delivered and used eight aircraft, just now it seems, the Modu Aircraft Factory is indeed a thriving scene, even McDonnell Douglas is optimistic that the original expected MD-11 passenger aircraft sales of 300 to sell 450, it can be said that the two sides are now the king of the eight mung beans, it is really eye-to-eye.

In this case, Yang Hui actually thinks that if it can continue, maybe it can be regarded as a different road for the revitalization and development of the aviation industry, but it is a pity that Yang Hui is still very clear that history is still crushing all the way.

First of all, McDonnell Douglas's corporate performance is still worse than the previous year, and the first quarter is even worse than the first quarter, and there is now a need to integrate the domestic civil aviation aircraft manufacturing industry in the United States to confront Airbus, which is growing stronger and stronger.

But fortunately, the current AVIC Southwest has indeed begun to gradually come into contact with the design and production materials of some MD-11 transferred by McDonnell Douglas to the Modu Aircraft Factory, especially the large fuselage partition frame, which has been delivered in batches for final assembly under the forging of the large press of AVIC Southwest, and these are naturally under the pressure of the 10,000-ton large press of AVIC Southwest.

"I have long heard that AVIC Southwest has built a world-class large-scale pressure equipment center, hydraulic die forging, hydraulic free forging, and even 40,000 tons of vertical extruders. I look at it now, it is really extraordinary, it can provide the manufacture of large structural parts for the MD-11, an aircraft with a maximum take-off weight of more than 200 tons, and the manufacturing of structural parts for our 120-ton medium-sized transport aircraft is certainly not a problem, and everyone can develop the project with confidence. ”

Joke, now the situation is like this, it must be a hundred rest assured, this new China Transport is a total of these technical difficulties, the manufacturing of aircraft load-bearing structural parts by AVIC Southwest, and the need for a lot of technical research, aerodynamic testing of the wing, the central wing box is also by AVIC Southwest hand bag, left to Germany there really is not much key technology to tackle.

After Yang Hui carefully calculated the whole project, he found that there are still great difficulties in the design of the landing gear of the new Zhongyun, after all, this aircraft needs to land in a short distance at the front-line field dirt airport, so the requirements for the landing gear are indeed not low, but this thing obviously cannot be designed and manufactured by the MM company itself, it must be entrusted to the international landing gear giant Liebherr company of Germany, which is still one of the few remaining aviation industry essences in Germany.

In addition, avionics design belongs to the design that can be completed by anyone in China and Germany, and it is directly handed over to MM company without much objection, so that the only thing left that needs to be spent by MM company is probably a variety of pull orders, which may also be regarded as a major difficulty of the project, and even directly related to the final success or failure of the project and profitability.
