In the box, a table of sumptuous and exquisite dishes, a bottle of good wine, the three of them chatted while eating and drinking, first talking about Li Dawu's promotion, and then talking about Li Dawu's personal problems.

Zhang Can said: "Dawu, it's 31 this year, it's time to find a partner." ”

Li Dawu said: "Time flies so fast, it's been 7 years since I resigned from Factory E, and I really should find a partner." ”

He Baitao said: "Dawu, there are a lot of beauties in our company, or brother, I will introduce you to one." ”

Li Dawu said: "Go, go, I already have a goal, but it's not our company." ”

Zhang Can smiled, and then said: "Dawu, Lao He and I are both from here, otherwise, let's take a pass for you and take a look at this girl?" ”

Li Dawu said: "Forget it, it's still me who comes, besides, we just started to get in touch, and she doesn't know my true identity yet." ”

Zhang Can smiled and said, "Dawu, you are going to pretend to be a pig and eat a tiger to deceive other little girls." ”

Li Dawu said: "Go, go, am I that kind of person?" ”

The three of them talked and laughed, a meal, ate for a long time, were full of wine and food, the three of them went out of the private room, in the corridor, a few words of Japanese sounded in their ears, the three of them were stunned, did not think that they could meet the Japanese here.

The door of a private room next to it opened, and several people walked out of it, two of whom spoke Japanese, but when they saw Zhang Can and others, they immediately changed their words to Mandarin.

Zhang Can, He Baitao, and Li Dawu all glanced at the few people who had just come out of the box, and the other party was also three people, in addition to the two who spoke Japanese just now, there was also one person, wearing a black suit and glasses. About thirty years old.

Zhang Can and the three of them didn't pay too much attention, but they just felt a little strange, and when they walked out of the restaurant, He Baitao said with a smile: "I didn't think that I could meet a little Japanese devil here." ”

Zhang Can and Li Dawu smiled, and Li Dawu glanced back. Just now, the three of them were also about to leave the restaurant, and one of the little Japanese people bent down to salute, as if to say, "Please!" ”

I didn't really hear it, and I just glanced back, Li Dawu didn't pay attention to it, everyone got in the car and drove away together.

Tianfeng Technology Company, Chengnan Base.

The No. 1 workshop of more than 10,000 square meters not only has personnel wearing Tianfeng Technology Company's work clothes. There are also some personnel from a well-known machine tool and equipment factory in China.

In the huge workshop, on the floor of epoxy resin, the smooth and clean can shine the figure, and the whole workshop has completed the planning.

The yellow and red paint lines have drawn out the safety passages, logistics passages, and even the installation location of the equipment. It is also planned one by one.

It's clear where to install what equipment. And the whole workshop has completed the installation of multiple equipment sporadically.

More equipment is being transported from outside the workshop for installation and commissioning, and there are personnel from the machine tool equipment factory with the installation and commissioning.

In front of a large CNC vertical lathe. There are several people who are checking the accuracy of the equipment. Tianfeng Technology Co., Ltd. has also purchased a lot of equipment from China, and many of these equipment have been shipped to Tianfeng Technology Co., Ltd. to start the installation of equipment.

Zhou Ding, Li Dawu two. Walking into the No. 1 workshop side by side, just yesterday, Li Tianfeng officially signed the appointment document, appointing Li Dawu as the deputy general manager of the Chengnan base, and Li Dawu was appointed together, and there are two people, who are also deputy general managers, these two people, all of whom were middle-level positions before.

The promotion from a middle-level position to the deputy general manager of the Chengnan base is considered a high promotion, and of course, Li Dawu has been promoted from the general manager of the international industry and trade branch to the deputy general manager of the Chengnan base.

The International Industry and Trade Branch, with two manufacturing workshops and more than 1,000 employees in the entire branch, will surely reach tens of thousands of employees after the completion of the Chengnan Base, which integrates design and development, production and manufacturing.

On the first day of his appointment, Li Dawu went to the following workshops to take a look at the installation of equipment, the construction of unfinished workshops, and so on.

After looking around, Li Dawu walked into the office building, about to walk towards his office, in the lobby of the office building, the elevator door in the distance opened, and several people came out of it.

Two or three thousand design and technical personnel from the aircraft R&D and design center were temporarily working in the office building, and everyone got out of the elevator, talking and laughing, and walked outside, as if they did not know Li Dawu.

Most of the design and technical personnel in the R&D center are newly recruited, and Li Dawu has just taken up his post and does not know normal.

However, Li Dawu was stunned for a moment and recognized one of them, who was the person he saw in the restaurant two days ago, wearing glasses and a black suit, but now he was wearing a work uniform of Tianfeng Technology Company, no longer a suit and leather shoes.

The other party obviously didn't recognize Li Dawu, talking and laughing, walking past Li Dawu, Li Dawu thoughtfully, the other party was actually a technician of Tianfeng Technology Company, and it seemed that he was still a technician of the newly established aircraft research and development center.

Such a technician actually mingled with the Japanese, Li Dawu thought as he entered his office, and then picked up the phone and made a call out.

………

An aircraft factory.

Li Tianfeng and his entourage arrived here, and with Li Tianfeng, there were Sun Xiaoping and Qiu Wenan, and in addition, the military also had Zhang Haiping and several people.

This is the first time Li Tianfeng has been here, and it is also the first time to see the J-20 fighter at close range, before, at the beginning of the development of the turbofan 25 engine, and during the development process, naturally and the J-20 aircraft factory, as well as the J-20 fighter design and research institute, the three parties have had many technical exchanges.

In the aircraft assembly plant, Li Tianfeng saw the J-20 fighters undergoing final assembly, including a J-20 fighter, which was undergoing final assembly, but the position of the engine was empty.

Zhang Haiping said: "Mr. Li, the engine of this aircraft will be our turbofan 25, and when the engine is in place, it can be installed on the fighter plane for a series of test flights." ”

Li Tianfeng nodded, carefully looked at the engine compartment of the plane, looked at the situation inside, and then took a look at the J-20 fighter in general.

Zhang Haiping said with a happy face: "Mr. Li, how is our J-20 fighter?" ”

Li Tianfeng said: "It's not bad. ”

Next to him, the chief designer of the J-20 fighter said: "Mr. Li, the J-20 fighter, compared with the old American F22 fighter, there is still a certain technical gap, the main one is the engine problem, fortunately, the engine problem has been successfully solved by you." ”

The J-20 fighter, compared with the F22 fighter, naturally has a certain gap, Li Tianfeng just took a closer look at it, and saw a series of places that can be improved and perfected.

Even, Li Tianfeng thought in his heart that if he changed to his own design, the overall performance would increase a lot, and in addition, the stealth materials of the aircraft still needed to be improved.

Under the dark blue-gray stealth paint of the J-20 fighter (effective for multiple frequency spectrums), the rivets, openings and edges of the fuselage are almost completely invisible when you look at them. If you look closely, you can faintly see a few faintly visible side seams. This shows that the fuselage has good stealth materials, covering all the side seams and rivets of the engine.

The F-22's stealth paint is much thinner, like a varnish, with rivets, openings and edges on the surface clearly visible. Obviously, the stealth coating is not thicker and more advanced, on the contrary, the stealth material is so thick, which is precisely a manifestation of the lack of layers of stealth processing.

Li Tianfeng estimated that the stealth effect of the J-20 fighter is far from that of the American B2 bomber and F22 fighter. And even, most likely, inferior to the earlier F117.

Although there are some problems with the J-20, its advanced nature cannot be erased, and it truly belongs to the fourth generation fighter (according to Russian standards, it is considered a fifth-generation fighter), and the J-10 and J-11 belong to the third generation of fighters, which is a generation ahead.

If the J-20 fighter can be mass-produced, the overall strength of the Chinese Air Force will be greatly improved, and the gap with the United States will be greatly narrowed.

Praised by the chief designer of the J-20 fighter, Li Tianfeng said with a smile: "The turbofan 25 engine, the day when the J-20 fighter is officially installed will not be long, but I think the J-20 is a little expensive, and it is very difficult to mass produce." ”

As the chief designer of the J-20, Mr. Yang could only smile a little awkwardly.

Zhang Haiping sighed lightly and said: "The cost of the J-20 fighter is very high, more than 250 million US dollars, and our military is also unbearable." ”

Mr. Yang said: "The cost is so high, mainly because it involves some imported parts, in addition, the investment in research is not small, and in the end, the cost is high." ”

Li Tianfeng nodded, and even knew in his heart that if the research funds were converted into costs, the fighters of the J-20 fighter would be far more than 250 million US dollars, which was completely a money-burning thing.

The high cost of the J-20 fighter touched Li Tianfeng's heart, but Li Tianfeng did not speak too much, because the J-20 fighter was not developed by Tianfeng Technology Company.

This J-20 fighter has no vertical take-off and landing function, and Li Tianfeng has no way to do it for the time being, and the vector nozzle design of the turbofan 25 engine is of little use in this J-20 fighter.

In addition, the aerodynamic performance design of the J-20 fighter is relatively conservative, which may be that the performance of the original engine is not enough, and the turbofan 25 engine is the most outstanding turbofan engine with a small channel ratio, such a conservative design, which is completely a waste of the turbofan 25 engine.

After returning from the aircraft factory, Li Tianfeng's heart was inevitably low, the turbofan 25 engine was so good, Li Tianfeng was even a little indignant.

This is typical overkill!

A few days later, Li Tianfeng didn't want to do this, there was only one goal, to develop the turbofan 25 engine smoothly, perhaps, a few years later, when Tianfeng Technology Company developed its own advanced fighters, it was possible to use the turbofan 25 engine as the engine of this fighter.
