Sun Xiaoping's heart also struggled fiercely, and he went to Tianfeng Technology Company, but he still didn't go. If you choose to go to Tianfeng Technology Company and participate in the development of such a turboshaft engine, you will become famous, and the development of advanced turboshaft engines is Sun Xiaoping's lifelong dream and lifelong pursuit.

But choosing to go to Tianfeng Technology Company, this is not easy, as the chief designer of the turboshaft C engine, it is impossible to go, which involves too many things from all sides.

Tangled, very tangled.

After a long time, Sun Xiaoping took a long breath and asked tentatively: "Mr. Li, can you really make such an advanced turboshaft engine?" ”

If it weren't for Li Tianfeng's extremely high technical level in the past, and he guided himself to improve the design of the fan blades of the turbofan B engine, Sun Xiaoping would definitely have brushed his sleeves away after reading such a design outline, which is not a deceptive thing.

Now it's different, since it was Li Tianfeng who came up with such a design outline, Sun Xiaoping was shocked and asked tentatively.

Li Tianfeng smiled confidently, "Mr. Sun, I am eighty percent sure that I can make an engine with such performance, of course, if Mr. Sun is willing to deign to help me and work with me on this turboshaft engine, then I am ninety percent sure." ”

Hearing this, Sun Xiaoping stood up slowly, walked around, thought carefully, weighed, and after a long time, Sun Xiaoping still sighed.

"Mr. Li, it's not that I don't want to come, but, hey, it's still a matter of importance, I'm a deputy chief designer, and if the chief designer of the turboshaft C engine resigns, the impact will be too great, the impact will be too great!"

Hearing this, Li Tianfeng couldn't help but feel disappointed for a while. His own design outline has come out, and it is when he needs someone to work hard with him, but Sun Xiaoping can't come.

Li Tianfeng said: "Then, Mr. Sun, you still have to think about it, the door of our Tianfeng Technology is open for you at any time." "Finished. Li Tianfeng's face could not hide his disappointment.

Seeing Li Tianfeng's disappointed look, Sun Xiaoping thought for a while and said: "Mr. Li, I have a college classmate who has a relationship between bunk beds, and my old classmate is currently a designer of the Fifth Design Institute and a professor-level senior engineer. If you are at a level, you may still be above me. ”

"Oh." Li Tianfeng seemed to see a glimmer of hope, but soon thought that since he was Sun Xiaoping's college classmate, he was afraid that his position was not low. I don't know what kind of model chief designer, what deputy chief designer or something.

Sun Xiaoping said: "Mr. Li, don't worry, my old classmate does not have any leadership and administrative positions in the Fifth Design Institute, and only has the title of professor-level senior engineer. ”

As if seeing Li Tianfeng's doubts, Sun Xiaoping said: "My old classmate suffers from his personality, he won't cater to it, and he is focused on technology." In addition, he is introverted and does not like words, and has worked for 20 years. Now he is only a supervising designer, and his title is to become a professor-level senior engineer with his own skills. ”

"Oh." Suddenly, Li Tianfeng became interested, such a person is what he needs, and he is introverted. If you don't like words, it's not a problem at all. His own Tianfeng Technology has the final say, as long as he really has the ability. It is not impossible to give him the post of chief designer of the model.

Thinking of this, Li Tianfeng expressed great interest and said, "Mr. Sun, tell me about your old classmate in detail." ”

Sun Xiaoping smiled, did not hide it, and told Li Tianfeng in detail what he knew, and after listening, Li Tianfeng said in his heart: "Qiu Wenan, it's you!" ”

Sun Xiaoping's ancient scientific name is "Qiu Wen'an". Li Tianfeng thought in his heart, although he didn't bring Sun Xiaoping over to join his Tianfeng Technology Company, if he could get Qiu Wenan, it would be a big gain.

Qiu Wenan was originally unsatisfactory in the Fifth Design Institute and was very depressed everywhere, but he never thought that when he was in his forties, his fate would take such a magical turn, and he became famous and became a well-known aero engine designer in China.

Asking about Qiu Wen'an's situation, Li Tianfeng said: "Mr. Sun, I disturbed you today, I still said the same thing, the door of Tianfeng Technology is open for you at any time, you can come at any time, I welcome you at any time." ”

In fact, Sun Xiaoping's heart is very entangled, I don't want to go to Tianfeng Technology, it must be fake, Li Tianfeng's hands can hold the design outline of the most advanced turboshaft engine in China, if he can participate in the research and development, and if he still plays an important role, he will have no regrets in this life.

As an aero engine designer, and a designer with a good level, I can imagine the yearning in my heart when I encounter such a project. It's like a good calligrapher who suddenly sees an ancient famous post.

The two chatted for a while, drank tea for a while, Li Tianfeng got up to say goodbye, and when he left, seeing the tangled look in Sun Xiaoping's eyes, Li Tianfeng said in his heart, there may be a play, wait for a while.

"Mr. Sun, then thank you, you can help me contact your old classmate first." Li Tianfeng said.

Sun Xiaoping said briskly: "Mr. Li, don't worry, I will definitely be a good lobbyist, mobilize my old classmate, build a good bridge for you, and pull a good line." ”

Seeing Sun Xiaoping so humorous, Li Tianfeng laughed, the slight disappointment in his heart was swept away, and together with Sun Xiaoping, he laughed and walked out of the teahouse.

……

After the Lantern Festival, Wei Jin's family has returned to Songzhou, and Wang Ruobing is a little late, Wang Ruobing, who is already a senior, although his studies are already very easy, he still has to go to school first and come back after a while.

In the past few days, Li Tianfeng has basically talked to Wang Ruobing on the phone every day, and sometimes, Wang Ruobing will take the initiative to call, although there is no affection on the phone, but there is talk and laughter, and both of them seem very cheerful.

No, in his office, just after dealing with a few points, Wang Ruobing's phone called, the two talked and laughed, and cooked phone porridge for almost half an hour, and finally, Li Tianfeng said: "Ruobing, then say okay, I will come to the airport to pick you up." ”

"Well, that's settled, I'll call you then." Wang Ruobing said happily.

ended the call, and Li Tianfeng's heart was also happy. Enthusiastically, I reviewed a new process specification sent by the process technology department.

As the boss of Tianfeng Technology, Li Tianfeng is also relatively busy, with more and more parts from the E factory to process, and more and more process regulations are compiled, Li Tianfeng can no longer do each process specification carefully reviewed.

A review of the process regulations, as short as one or two hours, as long as three or five hours, the workload is not small, at present, Li Tianfeng only reviews some important parts, the processing process of key parts, and some of the processing process procedures of the parts that are difficult to process.

As for the processing technology regulations of some general parts, Li Tianfeng has already delegated authority, and Zeng Qinghai and them will review it.

After reviewing a process specification in a good mood, Li Tianfeng's phone rang, and Li Tianfeng received the call, feeling slightly strange in his heart, the call was actually from Tang Jianyi.

"Mr. Li, I finally asked for your phone number, and I will call you right away." Tang Jianyì's tone sounded a little joyful.

Li Tianfeng said slightly strangely: "Expert Tang, I didn't expect to receive a call from you, it's really unexpected, Expert Tang, do you have something to do with me?" ”

Tang Jianyì This person likes to go straight and straight, everything is written on his face, and he won't be twisted and turned, otherwise, when he came to Tianfeng Technology last time, he wouldn't have thought that the processing technology of the flame cylinder was wrong at the beginning, so he directly gave his face, which almost caused a misunderstanding.

However, the finishing of the flame barrel was perfect, and it almost convinced Tang Jianyì, an old expert, and his attitude and tone were much better and more polite.

This time, Tang Jianyì was not polite, but said directly: "Mr. Li, I heard that a batch of blanks of turbofan B compressor wheels from Factory E came over, which are being processed by you, and I want to come and take a look." ”

Li Tianfeng said with a smile: "Expert Tang, why are you interested in these turbofan B compressor roulettes?" ”

"Mr. Li, it's hard to say." Speaking of this, Tang Jianyì seemed to be full of feelings, and his mind also came to mind the days and nights when he carried out process public relations, thinking of this, Tang Jianyì said: "Mr. Li, these compressor wheels are not easy to process, especially the spokes of fine wheel discs, which are very difficult, I want to come and take a look." ”

The turbofan B compressor wheel disc is like a disc, but there are precision mounting holes on it, and the outer circle has a tenon and groove for installing the blades, the structure is relatively complex, titanium alloy material, the parts are very thin, very light, and the processing difficulty is relatively large.

In particular, the wall thickness of the spoke plate of the wheel disc is only 2.1 mm, and the so-called "spoke plate" is the wall plate of the wheel disc radial perpendicular to the axis of the wheel disc, because the wall thickness is only 2.1 mm, and the wall thickness tolerance, the end face runout requirements are extremely strict, and the processing difficulty has been great.

Obviously, Li Tianfeng also knew the difficulty of processing this kind of parts, and he seemed to be a little sure in his heart, so he smiled slightly: "Expert Tang, it just so happens that the ninth-stage roulette of the turbofan B compressor will soon enter the finishing process, if you are free now, I will send a car to pick you up." ”

"Oh, Mr. Li, the ninth stage roulette is one of the most difficult to process among the nine compressor discs from the first stage to the ninth level of the entire compressor, I didn't expect you to carry out the finishing process, I'll come here, come right away."

After the two talked on the phone, Li Tianfeng made another call to Liu Wei, told Liu Wei of Tang Jianyì's phone number, and instructed Liu Wei to send a car to Factory E to pick up Tang Jianyì. “

Putting down the phone, Li Tianfeng thought in his heart, the finishing processing of the ninth-level roulette disc should also take a look, the finishing of this part is not simple.

So, Li Tianfeng picked up the work cap and put it on his head, and walked to the No. 1 production workshop.
