It was Smith's assistant Joseph who knocked on the door and came in, and when he saw Joseph, Smith said happily: "Joseph, come, come, take a look at the test flight report of the turbofan 17 engine sorted out by the technical department, the turbofan 17 engine is even better than we imagined and expected." ”

Seeing that his boss was completely complimenting the turbofan 17 engine, Joseph, who had come in to report, couldn't help but swallow back the words that came to his mouth.

Smith, who was in the midst of joy and joy, didn't notice Joseph's expression for the time being, but continued to say happily: "Joseph, what do you think will happen if our plane is equipped with turbofan 17 engines?" ”

Joseph said: "BOSS, the turbofan 17 engine is naturally a very good engine, if our aircraft is equipped with a turbofan 17 engine, I think it will be more fuel-efficient, more comfortable and more competitive." ”

After thinking about it, Joseph hesitated and said, "But ......"

At this point, Smith finally noticed the anomaly and couldn't help asking, "Joseph, is there something wrong?" ”

Joseph said truthfully: "BOSS, last month, Embraer ordered a large number of engines from Tianfeng Technology, including a lot of turbofan 17 engines. ”

"Is there such a thing?"

"BOSS, it's true, although we don't know the price and quantity of the engines ordered, but it is an ironclad fact that a large number of engines are ordered."

Hearing Joseph say this, Smithton became brooding, frowning, and walking up and down his office, his expression becoming more and more solemn.

It is no secret that Tianfeng Technology and Embraer signed a large order in the Songzhou region, even in the domestic aviation industry. A lot of people know about it.

Abroad, as far away as Canada, Bombardier will have to lag behind when it learns the news, so Joseph reported it to Smith.

After thinking for a long time, Smith said, "Joseph." I have to report this to the board of directors right away, and if possible, I'm going to go to Tianfeng Technology in person. ”

Joseph hurriedly said: "BOSS, then I'll go through the relevant procedures immediately, and we'll go to Tianfeng Technology Company as soon as possible." ”

Smith nodded and said, "Okay, go through the formalities immediately, I want to go to Tianfeng Technology Company as soon as possible." ”

With that, Smith walked briskly out of his office, obviously. I went to my boss to report the new situation.

If it had been before, Smith would definitely not be in such a hurry when he heard such news, but as the turbofan 17 engine completed a series of test flights, as he gradually understood this engine, Smith couldn't help but feel anxious.

Tianfeng Technology Company.

Li Tianfeng was looking at the turbine rotor design of the turbofan 17 engine, which was the design drawing after further improvement and refinement. Li Tianfeng looked very carefully.

Even, some sizes and technical conditions. Li Tianfeng will personally calculate it again to ensure that nothing goes wrong.

Just the day before yesterday, Sun Xiaoping organized a design review meeting for the turbine rotor, which Li Tianfeng personally attended, and everyone completed the design review of the turbine rotor together.

This review has a lot fewer questions than last time. There are only a few small problems, because the design of this turbine rotor, Li Tianfeng has carefully read it before, and the design has been improved and perfected in Li Tianfeng's requirements.

In addition, after completing the refinement and refinement. The aero engine R&D center itself organized an internal design review, and the second review in the first two days belonged to the second review, and there were naturally very few problems.

There were only a few minor problems, and the design of the turbine rotor was also slightly improved and perfected again, and after completion, the design drawings were sent to Li Tianfeng.

In his own computer, Li Tianfeng looked at it carefully and carefully again, and after calculating, Li Tianfeng picked up the phone and called Sun Xiaoping's office directly.

Li Tianfeng said: "Mr. Sun, there should be no problem with the turbine rotor, you can issue formal design drawings, and then, the turbine casing, and other parts of the turbine part can be designed on the basis of this turbine rotor." ”

Hearing this, Sun Xiaoping was also greatly relieved, since Li Tianfeng said that there was no problem, then there must be no problem.

Sun Xiaoping said: "Boss, we will immediately issue the official design drawings, and immediately send the official design drawings of the turbine rotor to Mr. Zeng and them, I think, they have been waiting a little anxious." ”

Zeng Qinghai's process technology team has been waiting for the official design drawings of the turbofan 20 engine, as soon as the drawings arrive, the preparation of process regulations will be carried out in accordance with the design drawings.

The tradition of Tianfeng Technology Company does not necessarily complete the design of a certain engine, and the manufacturing of process specifications is carried out only after all the design drawings are released.

As long as there are formal design drawings, even if it is a certain part of the design drawings, the preparation of the process specification will be carried out immediately according to the design drawings, and the drawings will come out first, which can greatly shorten the development cycle of the engine.

As far as the domestic industry is concerned, other aviation industry enterprises may not be able to do this, because the risk of doing so is too great, in case the design has to be pushed to the beginning, or face major changes, according to the original design drawings of the processing and trial production of parts may be scrapped, so that the previous series of processing and trial production is in vain.

There is basically no such situation in Tianfeng Technology Company, Li Tianfeng has a spectrum in his heart, and the design drawings that have generally been checked and reviewed by Li Tianfeng will generally not make major changes, at most only some small changes, even if they are small changes, they are generally very few.

Because of this, as soon as some of the design drawings come out, the process specification will be compiled immediately for the trial production of parts, and the development cycle of aero engines will be greatly shortened.

The turbofan 20 engine and the turbofan 19 engine competed, and in terms of the development process, Li Tianfeng naturally grasped it very tightly, and in Li Tianfeng's view, the sooner the development was completed, the better.

So, Li Tianfeng said: "Mr. Sun, as soon as the design drawings come out, they will be sent to Mr. Zeng's process technology department as soon as possible, and they will immediately enter the trial production stage of parts." ”

Sun Xiaoping said: "Boss, there is no problem, the design drawings of the turbofan 20 engine, every drawing that comes out officially, we will send it to the process technology department as soon as possible." ”

Li Tianfeng said: "Although there is a certain risk in our operation, it can greatly shorten the development cycle, which is completely worth it." ”

Sun Xiaoping said: "Boss, the turbofan 20 engine is designed on the basis of the turbofan 16 engine core engine, this risk is very small, we are confident that once the design drawing is issued, it will generally not be changed." ”

Li Tianfeng nodded, this is the best.

Process Technology Department.

The first formal design drawing Zeng Qinghai received was the turbine rotor design drawing of the turbofan 20 engine, which not only included the general design drawing of the turbine rotor, but also a complete set of design drawings such as turbine blades, turbine disks, and turbine shafts.

Wu Shungao used to be a senior engineer of E factory, when the national aviation industry system technical skills competition, Wu Shungao also won the ranking of the process group, at the beginning, Li Tianfeng was the first, Zeng Qinghai was the second, Wu Shungao was the fifth.

At the same time, Wu Shungao is one of the first technicians to join Tianfeng Technology Company, and now Wu Shungao is already Zeng Qinghai's right-hand man, the deputy minister of the process technology department of Tianfeng Technology Company, with an annual salary of hundreds of thousands, which can be regarded as a successful career, and the original E factory is completely on the ground and a sky.

Zeng Qinghai took this large stack of design drawings, put them on the reading table, and said happily: "Shungao, the R&D center is really fast, the design drawings of the first batch of turbofan 20 engines have come out, you can also take a look." ”

Hearing this, Wu Shungao was also interested, picked up one of the design drawings, which was the design of the turbine shaft, and after looking at it carefully, he said: "Mr. Zeng, the overall turbine shaft has not changed much, and we can learn from the processing technology of the turbofan 16 engine turbine shaft." ”

Zeng Qinghai also said: "I think it is completely possible to learn from the processing technology of the turbofan 16 engine turboshaft, but the process parameters need to be changed slightly, and the process route can be basically the same." ”

Wu Shungao picked up a design drawing of the low-pressure turbine disk, looked at it carefully, and said in surprise: "Mr. Zeng, the amount of changes in the low-pressure turbine disk is not large, and its structure is basically similar to the low-pressure turbine disk of the turbofan 16 engine. ”

Zeng Qinghai said: "I have basically read these drawings, and the amount of change in each part is not large, and we can learn from the processing technology of the turbofan 16 engine." ”

Wu Shungao said: "Mr. Zeng, in this way, whether it is the preparation of process regulations, or the trial production of parts, as well as the verification of the process, it will save a lot of trouble, and it will definitely be a lot smoother." ”

Zeng Qinghai said: "Shungao, turbofan 20 engine Li Zong's expectations are very high, we must not fall behind the R&D center, they completed the first batch of design drawings so quickly, then we must also complete the preparation of the first batch of process regulations as soon as possible." ”

Wu Shun nodded and said confidently: "Mr. Zeng, I will personally arrange this matter, the backbone of safety process technology, and complete the preparation of our first batch of processing technology regulations as soon as possible." ”

Zeng Qinghai was very happy, "Shungao, then this matter will be handed over to you, the preparation of the process regulations is completed, and we will personally review and review it to strictly ensure the quality of the process regulations." ”

The two were talking about the preparation of the first batch of process specifications for the turbofan 20 engine, while Li Tianfeng was answering a phone call from Beijing.

I saw Li Tianfeng's anxious face, and said loudly: "Okay, I'll come to the capital immediately, and I'll arrive in the capital this afternoon." ”

After receiving this call, Li Tianfeng had to hurriedly put down everything in his hand and immediately went to the capital.
