"Butcher, since the cause of the accident has been found, then I will go back today. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

Originally, it was thought that it would take at least ten days and a half months to investigate the accident, but who would have thought that the cause of the accident of the Jianjiao-5 would be found out so quickly by the 132 factory, so Yang Weining naturally did not have to continue to stay in the 132 factory to cooperate with the investigation.

Tu Kai hurriedly grabbed Yang Weining and said: "Xiao Yang, why are you in such a hurry to go back, anyway, when you go back to the 611 Institute, you are also engaged in your CAD project, it just so happens that I have already helped you ask Lao Lu for leave, and the hotel room has also been opened for you, you will stay for a few more days, in the past two days, I will let Xiao Liu take you to visit our production line, familiarize yourself with our technological process, and communicate with Hongfei them on flight issues." It's also very good for you to start projects in the future!"

Yang Weining hesitated, looked at Tu Kai's eager eyes, and nodded in agreement.

Tu Kai is right, although his mind is full of later generations, a kind of technical information, but in this era the overall level of China's aviation industry is still quite vague, which is not conducive to the development of the technology in his brain.

The aviation industry is an industry that combines scientific research and production quite closely, and if Yang Weining does not understand the current technical level of Factory 132, it will not be beneficial to his future development.

In the next two days, Yang Weining visited the aviation sheet metal center, finishing center, and assembly workshop of the 132 factory under the leadership of Xiao Liu, although he had enough mental preparation, but after seeing the J-7 production line of the 132 factory, Yang Weining was still disappointed.

In this era, there is a huge gap between China's aviation industry and foreign advanced levels in the fields of precision machining, aviation materials and microelectronics.

However, this is also a helpless thing, the aviation industry has always been a capital-intensive technology-intensive industry, in the case of the country's overall economic strength is backward, aviation science and technology want to reach the level of the United States, the Soviet Union, it is almost impossible.

As a simple example, the heat dissipation structure of turbine blades requires special alloy materials, and the production cost of this thing is almost the same as the price of the same weight of gold in this era, but in this way, China cannot do it without investing huge amounts of money in research.

There is also a fuel atomization device in the combustion chamber, which also requires a special structure and materials, and the price is almost equal to gold.

In addition, the aviation industry is more systematic than most people think.

For example, there are a lot of companies under AVIC that can't be beaten and don't seem to have anything to do with aviation at all.

When any aircraft is developed, there will always be a large number of units other than the aviation port such as the Chinese Academy of Sciences, China Electric Power, China Shipbuilding, and Aerospace.

This is only the first-level supporting units of the subsystem/sub-system, not counting the second-level supporting, third-level supporting and various outsourcing and so on.

In addition, the requirements of the aviation industry for various parts and components are different from ordinary industrial products.

Equipment that can work normally on the ground generally cannot work normally in various environments such as high and low temperature, high and low pressure, vibration, impact, rain, salt spray, etc.

Because of this, there will be all kinds of navigation beacon military standard requirements.

What we can see on a daily basis is usually just a narrow projection of the aviation industry in the ordinary industrial field.

Without Yang Weining's accurate judgment on the future development of the aviation industry and the prospects of various technologies, it would be really difficult for China to make achievements in the aviation industry without investing hundreds of billions of dollars and decades.

In fact, in Yang Weining's previous life, after experiencing rapid economic growth and decades of huge investment, the overall quality of China's aviation industry's front-line scientific research team has surpassed that of European and American aviation powers, and the application of various new technologies is much better.

A specific example is the electronic level of the J-20, which is better than the T50 or even the F22.

In particular, the J-20 can be called the flight control system against the sky, because this fighter uses canard wings and a full-motion double vertical tail layout, the aerodynamic control surface of the J-20 has almost reached the extreme of a fighter in history, even if the F-35 that later adopted many new technologies can not compare.

For another example, the large-size titanium alloy 3D printing technology of Yun 20 not only greatly reduces the cost compared with the old United States when it does f22, but also makes all the indicators better than the old United States.

At that time, China did not lag behind many new technologies in the aviation industry, on the contrary, some of them may have done better than those of European and American aviation powers.

However, there is another very important feature of the aviation industry, and that is the barrel effect.

Due to China's long-term backwardness in basic science, especially in fields such as materials science, which require long-term capital investment, not to mention the old United States, even the fallen Maozi, Britain, France and other countries that have been stagnant for a long time cannot compare.

Because of this, what really hinders the development of China's aviation industry is not those short-sighted technocrats, nor all kinds of technical shortcomings, but capital investment.

Money is the core issue of whether China's aviation industry can catch up with aviation powers in the future.

After visiting the production line of Factory 132, Yang Weining thought for a long time, in addition to carefully combing the development line of various new technologies in his mind, he felt the great responsibility on his shoulders.

These technologies in my mind can not only lead the development of China's aviation science and technology in the future, but are more likely to be the largest source of funds for the aviation industry in the dark period after the country shifts its focus to economic construction.
