Chapter 341 completion of COMAC production line

Just after Zhang Yunfeng sorted out the organizational structure of Dongchen charity fund and established it completely, the complete set of production line equipment ordered by Dongchen from Qualcomm and Texas Instruments arrived in China, and started to be established in Jiangcheng. Most of these equipment were not produced by Qualcomm and Texas Instruments, but various equipment were transformed and modular by Qualcomm and Texas Instruments It has been established to the top level in the world.

Although this kind of thing is high-end, Americans never ban it from China. It's a terminal device in a special field, rather than a high-precision processing device. Like that, it also has a high value in other fields. If you have enough scientific research level, you can purchase and assemble a set from the world. It doesn't take much time. But in the global processor market, the United States Enterprises account for the vast majority of shares, and other developed countries can hardly catch up with them, which is the advantage of technology monopoly.

However, for Zhang Yunfeng, what he lacks is just time. If everything starts from scratch, Dongchen needs to spend a lot of time in the preparation stage no matter what he does. Therefore, he must try to buy ready-made ones to save himself as much time as possible.

Even though the two sets of equipment have arrived, they still can't meet the requirements of the sophomore. Next, the sophomore will continue to upgrade and transform on this basis. In this period, Zhang Yunfeng can't save it in any way, because he wants to surpass the existing technology on the basis of the current top technology, until no one can reach it in this era.

Two production lines will be used in the production of microprocessors in the future, one for CPU production and the other for GPU production. As for memory particles, Zhang Yunfeng doesn't need to import them from abroad. He can meet the requirements of sophomore by purchasing from home and refitting them.

At the same time, COMAC's aircraft engine production line in Zhonghai, after a long and huge transformation project, was finally completed. The modified production line basically achieved 90% automation, while COMAC transferred a group of top domestic technicians into Zhang Yunfeng's hands to complete the remaining less than 10% of the labor links, which also means that Zhang Yunfeng's industrial empire Take the lead and go further.

After the completion of the production line, the next step is to enter the actual production stage. Zhang Yunfeng finds out all the materials of the world's civil aviation system, uses his unforgettable skills to see all the materials thoroughly in a short time, and then starts his own analysis of the industry.

The civil aviation industry is now very developed in the world. Even in China, it has a considerable scale. As far as the current attendance rate of domestic airlines is concerned, the whole industry is in a golden period of vigorous development. Domestic airlines, on domestic routes of more than 800 kilometers, have a considerable competitiveness. In the field of international aviation, civil aviation is the largest The first choice for several people to enter and leave the country is the civil aviation system of the whole world. There are nearly 20000 various types of airliners, most of which are mainline airliners, and the number of regional airliners within 100 seats is very small.

The trunk airliner has always been the core of the whole civil aviation field, just like Boeing and Airbus. The two smallest airplanes are the 737 and A320 series with more than 100 seats. Moreover, because of the different seat rates and competitors, the most allocated airliner by civil aviation companies is the 100200 seat trunk airliner, such as 737 and A320. The price of such airplanes Low cost, small cost, more accurate and appropriate control of attendance, will not bring too much waste of resources.

Boeing 737 has a total production of more than 8000 models. China's airlines alone have at least 500530, while Airbus A320 has a very high production, with a total production of more than 5000. It can be said that only these two series of aircraft occupy half of the civil aviation field.

Zhang Yunfeng's first entry point is to start with these two planes. The standard configuration of 00 seat civil aviation airliner is to hang two turbofan engines. The thrust of each engine is about 80009500 kg. The design of large bypass ratio has higher thermal efficiency and higher economy, but the acceleration is slightly inferior to that of small bypass ratio engine. However, for civil aviation, the large bypass ratio is the most economical and practical design.

Zhang Yunfeng is going to let Xiaoer bring out the turbofan engine technology in 30 years. Although the current production line level and material level are not up to the standard in 30 years, the products actually produced can also be at least 20 years ahead of the current world science and technology.

For civil aviation, cost is always the biggest problem. The price of Boeing 737 series varies from 50 million US dollars to nearly 90 million US dollars. Its maintenance costs are extremely high, and the service life of aircraft engine is limited. Even for civil aviation, the engine needs to be overhauled in more than 3000 hours, and almost all parts are replaced Depending on imports, the price is very high.

However, the cost of civil aviation is also very high, and the fuel consumption is very high. Sometimes, the occupancy rate is low, or the landing process of the aircraft is delayed by the air traffic control for a long time. When this line flies down, the airline will lose money. People with multiple flight experience are very clear about the importance of the base airport to the airline It's faster to get there, because the base airport of China Eastern Airlines is in Zhonghai. When several airplanes are queuing up to approach and land, the base airport will give priority to landing their own airplanes, while some unlucky ones need to hover in the sky for dozens of minutes before they can get permission to land.

Not only that, sometimes the weather is cold, and the aircraft body is covered with ice in the high altitude and low temperature environment. After landing, the cost of one-time deicing will cost tens of thousands of yuan, sometimes even hundreds of thousands.

Therefore, civil aviation companies attach great importance to cost control. They prefer to choose airliners and engines with higher cost performance ratio. When it comes to civil aviation cost, fuel and maintenance have always been the largest continuous cost expenditure of civil aviation industry.

The new engine design will adopt the most advanced rotor technology, and the turbofan will also be designed by Dongchen and manufactured with high precision. In terms of material use, the weight of the engine with the same thrust can be reduced by more than 30%, the service life can be easily doubled, and the combustion process is more scientific. Under the same thrust, the fuel consumption will be reduced by at least 3040%. Due to the special design and manufacturing Technology, noise can be greatly controlled, decibels, compared with the current engine, reduce at least 28 decibels.

If the engine wants to meet this standard, it is not only the manufacturing process, but also the material. The large fan adopts hollow titanium alloy or composite material. Zhang Yunfeng prefers the latter, because if the latter adopts higher technology, the cost can be greatly reduced, and most importantly, the performance is better than the current titanium alloy.

In addition, the most important one is the single crystal superalloy for manufacturing turbine blades, which has always been one of the core secrets of a large country of science and technology. It will never export materials to the outside world, even if it has, it will only export the whole machine, and will not give the other party any chance to make use of it.

It's not difficult for Zhang Yunfeng to produce these materials. As long as he provides his own technology, with Zhongchen's technical strength, he can complete the manufacturing in a short time. Moreover, the technical level of the materials will be far higher than the current top technology. However, the strategic significance of this material is far more important than that of high-strength steel alloy. Does Zhongchen have the ability to protect this secret? Zhang Yunfeng has What's more, will the senior management rest assured and boldly let a private enterprise carry out the production of this extremely high-end material?

In order to solve this problem, Zhang Yunfeng's first stop is not to go to COMAC's production line in Zhonghai, but to take a private plane to Yanjing to meet Nie Minhui.

What kind of position does the Su family have in the senior management? Zhang Yunfeng is still confused. And he doesn't want to find out. It's like Su Yunfeng, Su nuoyan's father. Zhang Yunfeng has never known what his position is in the government. His repeated contact with Su Yunfeng also makes him feel that because of Su Yunfeng's special identity, he has made himself contact with Su Yunfeng It's hard for him to say anything like himself and Nie Minhui, and he won't have inexplicable pressure and formality.

Up to now, Zhang Yunfeng is still very sensitive to senior leaders. For senior leaders, he has only contacted with Director Liu. In a reasonable way, he should also greet director Liu and ask for senior opinions indirectly through it. However, Zhongchen is a joint venture established by Dongchen and Zhongyu, with one accounting for 51% and the other for Nie Minhui Shares 49%, plus Nie Minhui is his future mother-in-law, this kind of thing, first discuss with her, is the most appropriate.

Nie Minhui is very busy recently. Zhongyu's own business is mainly steel manufacturing. However, the competition of low-end steel in China is very big. Dozens of steel-making enterprises, large and small, regard low-end steel as the top priority, and the profit space has been constantly suppressed. Although the profit of high-end steel is higher, it is frequently suffered by foreign super large enterprises Recently, the most powerful Nippon Steel in Asia has made a full impact on the domestic high-end steel market. With a higher level of technical strength, Zhongyu has been losing in front of Nippon Steel.

Nie Minhui sometimes thinks angrily that Zhongyu does not have an absolute advantage in high-end steel. However, Zhongchen's high-strength steel alloy is the best high-end steel in the world. Even the state explicitly prohibits the export of materials, and only approves Dongchen to export finished automobile parts. Otherwise, if we mass produce this steel alloy, Nippon steel will be grey for a long time I'm rolling home.

Hearing that Zhang Yunfeng called to have an interview with him, Nie Minhui had to temporarily suppress her negative emotions. She also knew that some of the high-end high-strength steel alloy products produced by Zhongchen were too outrageous. This high-end material must be covered in the pocket, which could not be taken out to others.

With Zhang Yunfeng about the club that he often met before, Nie Minhui first arrived at Zhang Yunfeng, and Zhang Yunfeng hurried in half an hour later.

Seeing Zhang Yunfeng's dusty and anxious appearance, Nie Minhui couldn't help asking, "Yunfeng, what's the matter? Why are you so anxious to come to Yanjing?"

Zhang Yunfeng sat opposite Nie Minhui and drank a mouthful of water, but said: "the COMAC production line has been transformed. Now I am thinking that if we use the existing materials, the design performance of the engine will be greatly reduced. In order to ensure the technological content of the Dongchen aeroengine, I think that some special materials still need to be produced by Zhongchen."

Nie Minhui asked curiously, "special materials? Is there technology? "

"yes." Zhang Yunfeng said: "technology is ready-made, Zhongchen's design
