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

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 tomorrow."

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

The important position of Tianfeng Technology Company in Songzhou City, so the local government naturally dare not underestimate it. The secretary and the mayor came to visit instead of inspecting it.

Li Tianfeng smiled and said, "Secretary He and Mayor Chen came together. I was about to find these two people and tell them that we welcome their arrival."

Seeing Li Tianfeng agreeing, Liu Wei said, "Boss, then I will reply to them immediately."

Li Tianfeng nodded, and after finishing the call with Liu Wei, Li Tianfeng said, the secretary and the mayor came together, and this was probably the smell of a dock.

After thinking about this, Li Tianfeng felt happy and proud. Tianfeng Technology Company's status is getting higher and higher, and its scale is getting bigger and bigger.

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

In a good mood, Li Tianfeng put away the phone and walked to the static tester. Li Tianfeng gave some advice from a professional perspective.

This is the first static test, not the whole machine's static test, but the overall structural static test. It mainly checks the structural strength design of the whole machine. The whole static test machine looks a bit like a skeleton.

Structural static test is very important. The J-30 fighter not only has the ability to cruise supersonically, but also has excellent maneuverability. When the fighter maneuveres at supersonically and at high speed, all structural components will be subject to strict force assessment.

Especially in the high G state, this assessment is even more harsh. Li Tianfeng himself dares not underestimate it. Even if he knows that the structural design is very advanced and excellent, there is no problem in theory, but it still has to go through strict practical experiments.

From a professional perspective, Li Tianfeng also pointed out several issues. Zhou Yin and Lei Yong quickly wrote them down and will be improved immediately before the static test.

After watching the assembly of the static tester, Li Tianfeng went to the aircraft engine assembly workshop again and saw the turbofan 25b engine that was basically equipped.

The turbofan 25a engine is mainly used for the J-20 fighter jet, while the turbofan 25b is used for the J-30 fighter jet. The J-20 fighter jet does not have vertical take-off and landing, while the J-30 fighter jet has excellent vertical take-off and landing functions.

Compared with the turbofan 25b engine, the biggest difference between the turbofan 25a is that the turbofan 25b uses very excellent vector thrust technology, and the tail spraying parts are very different to a large extent. The rest of the parts look similar, and the amount of changes is not large.

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

Seeing Li Tianfeng coming, Sun Xiaoping said: "Boss, the 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, thank you for your hard work."

After saying that, Li Tianfeng looked at the engine seriously and the assembly resume of the engine. Li Tianfeng said: "Mr. Sun, the assembly quality control is good. Look here, the design requires the shaft to jump 2 wires, but in fact only half a wire."

Sun Xiaoping said: "The spirit of striving for excellence is deeply rooted in the hearts of employees. It is gradually becoming the essence of our Tianfeng Technology Company's corporate culture. Since Mr. Liu took office, he has put a lot of effort into this aspect."

As he was talking about Liu Peng, Liu Peng walked over quickly from a distance. When he learned that Li Tianfeng had entered the aircraft assembly workshop, Liu Peng walked over quickly.

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

Li Tianfeng nodded in praise, patted Liu Peng on the shoulder and said, "Mr. Liu, you did a good job. This turbofan 25b prototype has been assembled into a fine product by you."

After receiving praise, Mr. Liu looked happy and was extremely happy. 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 striving for excellence. Compared with the past, the quality of the engine has improved a little."

Li Tianfeng nodded with satisfaction.

Liu Peng and Sun Xiaoping together reported the assembly status of the prototype of the turbofan 25b engine.

After listening to the report, Li Tianfeng said: "Mr. Sun, after the turbofan 25b was successfully tested, the new development task is waiting for you again."

Upon hearing this, Sun Xiaoping was happy and immediately asked happily: "Boss, what new development task is developing a new engine?"

Li Tianfeng nodded and said, "Yes, the new engine, the new big channel is better than the turbofan engine, a civilian engine."

Tianfeng Technology's turbofan 21 engine, as an excellent power supply for civilian regional passenger aircraft, has basically monopolized the international regional passenger aircraft engine market.

The turbofan 21 engine is the main one and the turbofan 18 engine is the auxiliary one. These two engines occupy more than 70% or 80% of the international regional passenger aircraft engine market.

In the international trunk passenger aircraft engine market, Tianfeng Technology Company mainly has two engines, the turbofan 16 and the turbofan 17.

The turbofan 17 engine, a 20,000-pound rating engine, is used for 100 to 150-seat passenger aircraft, and if it is four, it is also used for trunk technology of 150-seat or above.

The turbofan 16 engine is a 50,000-pound grade engine, mainly used in 150-seat or 200-seat engines. In the 300-seat trunk passenger aircraft 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 can only be regarded as a world-class civil passenger aircraft engine, not a top-level one. The turbofan 21 engine using a second-generation core engine is the top-level civil passenger aircraft engine.

The market share of the turbofan 16 and turbofan 17 engines is naturally not comparable to that of the turbofan 21. In addition to the extensive use of these two engines at COMAC and the use of some turbofan 17 engines at Boeing and Airbus, these two engines do not have obvious advantages.

Boeing and Airbus purchase turbofan 17 engines in the market of 150-seat or 200-seat trunk passenger aircraft engines, and only compete with Rolls, Rolls, Ge, and Puhui.

As for the 300-seat or above 300-seat trunk passenger aircraft market, whether in Boeing or Airbus, there is no aircraft engine manufactured by Tianfeng Technology, which is inconsistent with Tianfeng Technology's growing reputation.

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

Sun Xiaoping had obviously been considering this issue for a long time. When Li Tianfeng mentioned this, Sun Xiaoping immediately guessed.

Li Tianfeng nodded and said, "A large engine with a 100,000-pound thrust level uses our second-generation core engine technology."

Hundred thousand pounds of thrust engine!

This is an engine that only the giants in the air use, such as large passenger aircraft such as the Airbus A380, Boeing 777, as well as some large military transport aircraft, large long-range strategic bombers, etc.

Sun Xiaoping thought to himself, is the boss going ahead and preparing to enter the field of large-scale aircraft research and development and manufacturing?

A turbofan engine with a thrust level of 100,000 pounds is definitely a giant. If it is a passenger plane, it is a giant four or five hundred seats. If it is a transport plane, it is a super large transport plane with a capacity of more than 200 tons.

Thinking of this in my heart, Sun Xiaoping felt a little excited and immediately said with a little excitement: "Boss, let's start developing this engine right away."

Tianfeng Technology's aviation engine research and development team has thousands of people, strong technical strength, and a series of engine development foundations. It even has the world's most advanced regional passenger aircraft engines and the most advanced military small-channel turbine engines, such as the turbofan 21 engine and the turbofan 25 engine.

Sun Xiaoping himself has a higher and higher technical level, and Sun Xiaoping is confident in the development of this engine.

Seeing that Sun Xiaoping was full of confidence, Li Tianfeng smiled slightly and said, "Mr. Sun, then I will ask you this difficult task, and you will be the chief designer of this engine."

Sun Xiaoping said: "No problem, we will start the development work immediately. After the design technical outline is released, I will give it to you for a review."

Li Tianfeng nodded and thought to himself that Sun Xiaoping and others should be confident of successful development. He is planning ahead and planning and preparing for the future in advance.

Li Tianfeng is definitely preparing to develop a large aircraft. Since he wants to develop a large aircraft, he must have a supporting engine, an engine with a 100,000-pound thrust level, which is considered for future consideration.

Songzhou City Secretary He Jun, Mayor Chen Anjie and his party arrived at Tianfeng Technology Company as scheduled. At about 9 a.m., a convoy drove over from Songzhou Avenue and stopped at the gate of Tianfeng Technology Company.

Li Tianfeng seemed quite polite and brought several senior executives to greet the company gate early. Seeing the convoy coming and stopping, Li Tianfeng smiled slightly.

Several cars stopped and the doors were opened. The first thing that came out was a few staff members and secretary. These people got out and opened the doors. He Jun, Chen Anjie and others got off the car.

Seeing Li Tianfeng standing not far away with a few senior executives facing a smile, He Jun and Chen Anjie looked at each other quietly, and they nodded slightly, then walked over quickly.
