. The factory was very cautious. He hoped to join the Russian fighter jet research project to cooperate with Kan Fan Dan's disease. Putin refused directly.

Although Russia is in extreme difficulties, it is absolutely impossible to exchange things that affect the major interests of the country. Especially for the Chinese, if they really want to absorb the design skills of the Russian military's top fighter jets, it is difficult to guarantee that they will not make breakthroughs in the shortest time. Russia will be directly affected by the time.

After all, Russia and China have a large area of ​​borders. Most cities in the Far East are not on guard against China. Once something happens, it feels like it is beyond reach.

Although Putin is determined to reform and has made great progress in the Russian economy and is expected to achieve greater achievements in a few years, he will never agree to Fan Wubing's request. He handed over the military's most important fighter jet technology.

Although Fan Wubing had this idea, he did not have too many extravagant expectations. After all, this was related to the fundamentals of the Russian military, and it was not easy to get them to agree. In fact, his real idea was just to raise some questions that made Putin difficult. It hurt him.

For Fan Wubing, it is very important to remind the owner of the Kremlin to remember the favors he owed him. At least when he makes more reasonable requests in the future, Putin should be able to accept the requests he had rejected before. Therefore, he agreed smoothly.

This should also be considered... art, the art of struggle.

At the end of August, good news came to Lingxi Province. The overall design and planning of the large aircraft project had been completed, and the details had been fully discussed and reasoned. After such a long time of preparation, the wind tunnel used for the large aircraft project test had been completed. On the basis of the Lingxi Airport, most of the original crew members who originally manufactured Y10, as well as the members of the large aircraft project team selected from all over the country have also begun to decompose the parts required for the large aircraft project according to the principles of in-house processing and off-site processing, and find the most suitable collaborators for processing and manufacturing.

"It is expected that this time, there will be more than 100 companies participating in the cooperation, and the construction period will be completed ahead of schedule. It is very likely that the prototype will be seen within two or three years, which is much better than before." Maximos, the ground executive of China Aviation Manufacturing Group, which is fully responsible for the large aircraft project, told Fan Wubing.

Fan Wubing was very happy about this, that is to say, if there is no major problem, he would be able to board a domestic large plane by the end of 2005 at the latest. According to the design capabilities, such a large plane can fly to any corner of the world.

Of course, the most critical issue is that the valuable information of the YTF project team, especially the motivation manufacturing technology, played a great role. After absorbing the advantages of Russian motivation technology, the motivation model obtained through the most advanced digital design method has maximized the domestic motivation technology to several levels, and has become a leading motivation technology that can be compared with advanced large aircraft. This progress has enabled the large aircraft project, which was originally expected to be promoted for ten years, and it can be completed within five years.

Another one is due to the breakthroughs in new materials technology in recent years.

When I was manufacturing the top ten aircraft projects, I had a concern that because the fuselage of large aircraft was too long and the materials could not achieve the best performance, some people were worried that during flight, the huge pulling force would gradually make the fuselage longer.

If the plane suddenly grows several inches after a flight, it is very problematic. Even if it flies into the sky, no one dares to fly a few more times. After all, the huge deformation will cause the plane to disintegrate in an unpredictable time, which is very terrible.

Even if there is no disintegration in the air, the longer and longer fuselage is a big problem. As the most precise aerial vehicle, there is no deviation, not to mention that if the fuselage metal processing technology fails, the aircraft will be several meters long, which is very good.

of.

Developing large aircraft is very costly, but it is also an important reflection of the country's economic strength.

.

Aircraft has only appeared for more than a hundred years, but it has become a product that symbolizes the entry of human society into the technological era. In addition to having great military value, it is also called the flower of science and technology economically. Many scientific and technological achievements of human society are gathered on aircraft.

At the same time, the aviation industry is also called the locomotive of industrial technology. The exhibition of the aviation industry will drive a wide range of social aspects to move forward. Therefore, in the second half of the 20th century, some people believe that if two important factors are mentioned, one should be attributed to the aviation exhibition and the other is the education exhibition.

The development of large aircraft is of course a very energy-consuming task, but it is also very economical. The aircraft industry is a highly knowledge-intensive, low-energy, low material consumption, and high added value. The unit weight price of aircraft and motors is three to five times that of electronic computers, more than ten to thirty times that of color TVs, and nearly a hundred times that of cars. In terms of consumption, the average raw materials used by each person in the aircraft industry, including fuel, are only one-third of the steel industry and one-half of the automobile industry.

Because of this, countries with husband-type aircraft regard it as the national pillar industry. It can be said that the civil aviation industry is an industry with great economic value, which is also an important reason why Fan Wubing wants to invest in large aircraft projects.

After all, although Mr. Fan is patriotic, he also loves money. He likes the most

.

During the century-old exhibition, aviation has pursued various technical indicators, such as degree, altitude, range, and battery life. However, in the past fifty years, various indicators have gradually stabilized. For example, the flight degree and altitude of the Y-Ten produced in China at that time are the same as the latest aviation product of Airbus, which is still in test flights today, and the waves that Boeing has not yet begun to develop.

The frontier position of the aviation technology exhibition is transferred to large passenger aircraft, mainly because large passenger aircraft brings huge benefits in food and economic benefits and has a great role in improving the country's comprehensive national strength and international reputation. Therefore, the exhibition of large passenger aircraft is a strategic arrangement, rather than a temporary arrangement needed at the moment.

Since it is a strategic issue, the most core is the overall design of the aircraft, which is comprehensive design. Putting all technologies in the divination is the most important thing. It is not a specific calculation and equality that requires comprehensive consideration of various possibilities.

Therefore, this time the overall design plan of the large aircraft project has been reviewed and entered the production stage. It is indeed a good news for Fan Wubing.

As for the general belief that there are three thresholds for developing large aircraft, technical, institutional and economic, they actually no longer exist. In fact, after the Y-10 was manufactured, it had already achieved a leap. At that time, we should have entered the club for the development of large aircraft in the world, but later withdrew. This withdrawal left the country many years behind in the large aircraft project, but with the wisdom of the Chinese people and the accumulation of aviation technology over the years, there were no insurmountable obstacles in technology.

As for the system obstacles, after the Yunshen was put on hold, due to various reasons, the airline was unable to embark on the road of innovation, and the airline was narrower and narrower. The current conditions were much better than that at that time. There were more opportunities to access new technologies, accept world intellectual achievements, and the injection of sufficient funds provided by Fan Wubing. The principle of independent opening was established.

The country has ranked second in the world's air traffic for many years, which is related to China's population base. When China's economy further rises, the total number of aircraft in the population increases, the required large passenger aircraft will be a huge market. Boeing, the United States, estimates that China will need at least 3,000 large aircraft in the future. Although the expected specific figures still need commercial and practical tests, such a huge domestic market needs are not available to other small countries.

China is the largest buyer in the world's common airplane field. It is said that the money used to buy planes today can be stacked with 100 new bills and can enter space. It is obviously nonsense to say that you can't afford to spend money to develop.

Just like overseas restrictions on domestic wafer manufacturing technology, if the country has its own large aircraft production and manufacturing base, then even if the market share has not yet become large, there will be a lot of bargaining chips when buying aircraft from abroad. The economic benefits in other places are far greater than the economic benefits of the aircraft itself.

In short, after Fan Wubing received this news, he immediately rushed to Lingxi Province and came to China Aviation Manufacturing Group Corporation. He invited the leaders of the General Equipment Department and the leaders of Lingxi Province to visit the factory together, and expressed his gratitude and condolences to the cadres and staff participating in the battle of the large aircraft project.

Of course, Fan Wubing naturally would not inform Boss Zhu. After all, the leader of this project team was personally held by Boss Zhu.

However, Boss Zhu seemed to have a lot of things to do and was not very interested, so he entrusted Fan Heng to Lingxi Province on behalf of the Central Committee and the State Council to inspect the progress of the large aircraft project and encourage him.

Fan Heng has not had many urgent matters on hand recently, and he has always been very concerned about the large aircraft project, so he accepted Boss Zhu's commission as soon as possible and flew to Lingxi Province by a special plane. He met with Fan Wubing and others to visit China Aviation Manufacturing Group Co., Ltd.

This time, the large-spec Ming alloy material development project of Southwest Aluminum Corporation has made a major breakthrough. Recently, a batch of domestic large aircraft aluminum alloy fuselage frame forging materials were successfully produced on the 30,000-ton hydraulic press of Southwest Aluminum Corporation. Since then, Southwest Aluminum Corporation has the ability to develop large-spec and high-performance aluminum alloy products.

Large aircraft refers to transport aircraft with a total take-off weight of more than 150 tons. Currently, only a few countries such as the United States, Russia and the European Union have manufacturing capabilities. Since the development of large aircraft is a high-precision project, each aircraft needs to use a large amount of aluminum alloy materials. After the domestic large aircraft project was launched, Southwest Aluminum Corporation also fully utilized its forging products for Boeing and provided the development advantages of advanced aluminum alloy materials for aerospace projects such as the Shenzhou series of spacecrafts. Internship in advance, a leading group for the development of advanced aluminum alloy materials for large aircraft and a large aircraft sub-project office were established, and some key special aluminum alloy materials in the large aircraft project were started to pre-research and trial production work.

The vice president of Southwest Aluminum Corporation also came to Lingxi Province this time to participate in this event. When meeting, Yu introduced to the leaders that the processing technology of large-scale stress-bearing components such as the fuselage frame of large aircraft has always been a cutting-edge technology that is internationally blocked. Without drawings to check or process information, the scientific and technological personnel of Southwest Aluminum Corporation developed a composite strong deformation process. After many tests and debugging, they finally broke through the problem of insufficient processing and deformation capabilities of existing supporting equipment and not deep deformation. They successfully increased the thickness of the product from rising to ugly in one fell swoop, filling the gap in the inability to produce ugly and thick components in China. They met the material needs of manufacturing large aircraft.

According to him, Southwest Aluminum Corporation has been shocked by hundreds of sets of large aircraft aluminum alloy supporting materials production orders with a total weight of about 700 tons. It is closely following the research needs of large aircraft related designs and equipment manufacturing units, and refining the research of key materials such as special aluminum alloy plates, profiles, forgings, etc. required for large aircraft projects.

In addition, Southwest Aluminum Corporation is also establishing a four-point three-meter wide thick plate hot-rolled production line and a large-tonnage tensile machine of more than 1:20,000 tons. After the project is completed, Southwest Aluminum Corporation will have the production capacity of large aluminum and aluminum alloy wide thick aluminum alloy thick plates for large aircraft, which can fill the domestic gap.

"Okay, now everything is ready, only the east wind is missing." Fan Heng was very satisfied with this.

Obviously, in the shortest time, the large-hair project entered a substantial operation stage. I came here when the large-hair project was planned to be established, and later I came here again when the China Aviation Manufacturing Group laid the foundation. This visit and congratulations on the overall design plan of the large-hair project passed the review.

If you can still stay in office in the next session, then you may come back when the large plane is officially tested. In other words, this project has grown up completely under your own care, which is of great significance.

I think Boss Zhu gave me this opportunity to visit and encourage me, but I hope I will start and end well and do this well.
Chapter completed!
