While answering the phone, Li Tianfeng walked a few steps to an open place in the distance, away from everyone. Everyone knew that Li Tianfeng was answering the phone, and everyone was watching the assembly of this static testing machine seriously.

On the phone, Liu Wei said: "Boss, I just received a notice from the Songzhou Municipal Party Committee Office that Secretary He and Mayor Chen will come to our company together tomorrow." ”

Guo Tongde was promoted, and the former mayor of Songzhou City also followed suit and was promoted to the top of a prefecture-level city, He Jun was transferred from the top of a department and bureau in the provincial capital to the top of Songzhou City, and Chen Anjie was promoted from the position of deputy mayor to mayor.

Tianfeng Technology Company is in an important position in Songzhou City, and the local government naturally does not dare to underestimate it, no, the secretary and the mayor came to visit together, not to investigate.

Li Tianfeng said with a smile: "Secretary He and Mayor Chen came together, just in time, I was about to find these two and tell them that we welcome their arrival." ”

Seeing that Li Tianfeng agreed, Liu Wei said: "Boss, then I will reply to them immediately." ”

Li Tianfeng nodded, and after ending the call with Liu Wei, Li Tianfeng said, the secretary and the mayor came together, this is the taste of the dock.

Thinking about this, Li Tianfeng was happy in his heart, and he was also proud in his heart, the status of Tianfeng Technology Company is getting higher and higher, and the scale is getting bigger and bigger.

Several major manufacturing bases, the company has 70,000 or 80,000 employees, with an annual output value and sales of more than 200 billion yuan, and it is expected to exceed 300 billion yuan this year.

In a good mood, Li Tianfeng put away the phone and walked to the side of the static testing machine, and Li Tianfeng gave him guidance from a professional point of view.

This is the first static test, not the whole machine static test, but the overall structure static test, mainly to check the structural strength design of the whole machine, the whole static testing machine is a bit like a skeleton.

Structural static testing is very important. The J-30 fighter not only has the ability to cruise at supersonic speed, but also has excellent maneuverability.

Especially in the high-G state, this kind of assessment is even more severe. Li Tianfeng himself did not dare to take it lightly, even if he knew that the structural design was very advanced and excellent, there was no problem in theory, but it still had to go through strict practical tests.

From a professional point of view, Li Tianfeng also pointed out a few problems, and Zhou Ding and Lei Yong hurriedly wrote them down, and they would improve them immediately before the static test.

After watching the assembly of the static testing machine, Li Tianfeng went to the aero engine assembly workshop again and looked at the turbofan 25B engine that was basically equipped.

The turbofan 25A engine is mainly used for J-20 fighters. The turbofan 25B is used in the J-30 fighter. The J-20 fighter does not have vertical take-off and landing, while the J-30 fighter has excellent vertical take-off and landing capabilities.

Compared with the turbofan 25A, the biggest difference between the turbofan 25B engine is that the turbofan 25B uses very good vector thrust technology, and the tail spray part is very different. The rest of the parts look similar, with little change.

During the final assembly process of this turbofan 25B engine, as the chief designer, Sun Xiaoping basically stayed at the final assembly site. When Li Tianfeng walked over, Sun Xiaoping happened to be there.

I saw Li Tianfeng coming over. Sun Xiaoping said: "Boss, the final assembly of the first turbofan 25B prototype will be completed today, and it is planned to enter the first test run tomorrow." ”

Li Tianfeng smiled and said, "Mr. Sun, everyone has worked hard. ”

After speaking, Li Tianfeng took a serious look at this engine and also looked at the assembly resume of this engine. Li Tianfeng said: "Mr. Sun, the assembly quality control is good, you see here, the design requires the shaft to run 2 wires, in fact, there is only half a wire." ”

Sun Xiaoping said: "The spirit of excellence. It is deeply rooted in the hearts of employees, and it has gradually become the essence of our corporate culture of Tianfeng Technology Company. ”

Just as he was talking about Liu Peng, Liu Peng walked over briskly from a distance, and learned that Li Tianfeng had entered the aircraft assembly workshop, so Liu Peng walked over quickly.

Liu Peng said enthusiastically: "Boss, you are here." ”

Li Tianfeng nodded approvingly, patted Liu Peng's shoulder lightly and said, "Mr. Liu, good job, this turbofan 25B prototype has been assembled into a boutique by you." ”

After receiving the praise, Mr. Liu was overjoyed and very happy in his heart, Liu Peng said: "Boss, whether it is the assembly of the turbofan 25 engine or the assembly of the turbofan 20 engine, now everyone adheres to the principle of excellence, compared with before, the quality of the engine has been slightly improved." ”

Li Tianfeng nodded with satisfaction.

Liu Peng and Sun Xiaoping reported on the assembly of the prototype of the turbofan 25B engine.

After listening to the report, Li Tianfeng said: "Mr. Sun, after the successful test run of the turbofan 25B, a new development task is waiting for you." ”

Hearing this, Sun Xiaoping was overjoyed and immediately asked happily: "Boss, what is the new development task, the development of a new engine?" ”

Li Tianfeng nodded and said, "Yes, a new engine, a new Dahan Daobi turbofan engine, a civilian engine." ”

Tianfeng Technology's turbofan 21 engine, as an excellent civil regional airliner power, has basically monopolized the international regional airliner engine market.

The turbofan 21 engine is the main engine, supplemented by the turbofan 18 engine, and these two engines occupy more than 7 or 80% of the international regional airliner engine market.

In the international trunk airliner engine market, Tianfeng Technology Co., Ltd. mainly has two engines, turbofan 16 and turbofan 17.

The turbofan 17 engine, a 20,000-pound engine, is used in passenger aircraft from 100 to 150 seats, and if it is four engines, it is also used in mainline technology with more than 150 seats.

Turbofan 16 engine, 50,000-pound class engine, mainly used for 150-seat class, or 200-seat class engines. In the 300-seat mainline airliner engine market, there is basically no turbofan 16 engine.

Whether it is a turbofan 17 engine or a turbofan 16 engine, the first-generation core engine of Tianfeng Technology Company can only be regarded as a world-class civil airliner engine, not the top, and the turbofan 21 engine using the second-generation core engine is the top civil airliner engine.

The market share of the turbofan 16 and turbofan 17 engines is naturally not comparable with that of the turbofan 21, except for the extensive use of these two engines in COMAC, as well as the use of some turbofan 17 engines in Bombardier and Embraer, in Boeing and Airbus, these two engines do not have obvious advantages.

Boeing and Airbus purchase turbofan 17 engines are not large, and turbofan 16 engines are only in the 150-seat or 200-seat mainline airliner engine market, along with Rolls-Royce, GE, and Pratt & Whitney.

As for the 300-seater class, or the trunk airliner market with more than 300 seats, whether it is in Boeing or Airbus, there is no aero engine manufactured by Tianfeng Technology Company, which is extremely inconsistent with the growing reputation of Tianfeng Technology Company.

Now, the turbofan 25B engine is about to enter the test stage, and Li Tianfeng is preparing to develop a large civil airliner engine to meet the needs of passenger aircraft engines above 300 seats.

Sun Xiaoping had obviously been thinking about this issue for a long time, and when Li Tianfeng mentioned this, Sun Xiaoping immediately guessed.

Li Tianfeng nodded and said, "A large engine with a thrust level of 100,000 pounds, using our second-generation core engine technology. ”

100,000 lb class thrust engine!

This is the engine used only by the air giants, such as Airbus A380, Boeing 777 and other large passenger aircraft, as well as some large military transport aircraft, large long-range strategic bombers and so on.

Sun Xiaoping thought in his heart, could it be that the boss is preparing to enter the field of large-scale aircraft research and development and manufacturing.

If it is a passenger plane, it must be a giant aircraft with four or five hundred seats, and if it is a transport aircraft, it must be a super transport aircraft of more than 200 tons.

Thinking of this in his heart, Sun Xiaoping was hot for a while, and immediately said with a little excitement: "Boss, we will start the development of this engine immediately." ”

Tianfeng Technology's aero engine R&D team, thousands of people, strong technical force, and a series of engines have the basis for successful development, and even the world's most advanced regional airliner engine, the most advanced military small channel turbine engine, such as turbofan 21 engine, turbofan 25 engine.

Sun Xiaoping's own technical level is getting higher and higher, and Sun Xiaoping is sure of the development of this engine.

Seeing that Sun Xiaoping was full of confidence, Li Tianfeng smiled slightly and said: "Mr. Sun, then this arduous task will be called to you, and you will be the chief designer of this engine." ”

Sun Xiaoping said: "There is no problem, we will start the development work immediately, and after the design technical outline comes out, I will send it to you for a look." ”

Li Tianfeng nodded, thinking in his heart, Sun Xiaoping should be sure of the success of the development, and he can be regarded as taking precautions and preparing for the future in advance.

As for the large aircraft, Li Tianfeng is determined to develop it, since he wants to develop a large aircraft, there must be a supporting engine, a 100,000-pound thrust engine, which can be regarded as a consideration for the future.

………

He Jun, secretary of Songzhou City, and Chen Anjie, mayor of Songzhou, arrived at Tianfeng Technology Company as scheduled, and at about nine o'clock in the morning, a convoy drove from Songzhou Avenue and stopped at the gate of Tianfeng Technology Company.

Li Tianfeng looked more polite, and took a few high-level executives to greet him at the gate of the company early, and saw the convoy driving over and stopping, Li Tianfeng smiled slightly.

Several cars came to a stop, the doors opened, and the first to come down were several staff members and secretaries and the like, who got out of the car and opened the doors. He Jun, Chen Anjie and others got off the car one by one.

Seeing Li Tianfeng smiling and standing not far away with several high-level executives, He Jun and Chen Anjie quietly glanced at each other, the two nodded slightly, and then walked over quickly.
