In his office, Li Tianfeng is completing a sketch of the design of the parts of the turbofan 20 engine, Li Tianfeng looked at this sketch with satisfaction, and thought to himself, he has drawn dozens of sketches, basically the slightly difficult parts design are all taken care of by himself, the design of this engine, there should be no problem.

Because of the need to ensure the high reliability and safety of the engine, the turbofan 20 engine basically adopts the technology that has been verified in the turbofan 16 engine, and the new design technology is relatively rare.

Because of the new design technology, it is necessary to carry out strict verification from beginning to end, even if Li Tianfeng himself knows that such a new technology must be no problem, but it is not possible, it must be comprehensively and strictly verified, and a special verification report must be formed.

Because of the technology that has been proven, the design difficulty of the turbofan 20 engine is not as great as imagined, and the most difficult should be in the fan part and the control system part, because these two parts have changed the most.

As for the other parts, the changes are relatively small, and even some parts are directly common to the turbofan 16 engine, even if they are not common parts, their design structure is basically the same, so that the design difficulty is greatly reduced.

Looking at his design sketch with satisfaction, Li Tianfeng thought in his heart, all the sketches of the parts that should be drawn have been drawn, and the task now is to draw another 3D color map of the turbofan 20 engine.

Open the professional drawing software, Li Tianfeng did it himself, this kind of work, at present, it is really only Li Tianfeng can do, in Li Tianfeng's mind, he has long conceived the three-dimensional graphics of the turbofan 20 engine.

However, the aero engine is very complex, even if Li Tianfeng's level of using drawing software is a master, but it will take at least half a month to complete.

In Li Tianfeng's plan. In addition to the panoramic 3D color map of the turbofan 20 engine, there will also be a quarter and a half cutaway.

The cut-out diagram of one-half can reflect the internal structure of the engine in more detail, because the engine is two from the central axis, like a big watermelon. After cutting it in half, you can clearly see the melon pulp and melon seeds inside.

Li Tianfeng sat in his computer, the first thing he began to draw was the panoramic 3D color map of the turbofan 20 engine, first starting from the parts, planning to draw several large casings, and then draw out the accessories outside the casing, and then assemble them together, and the 3D color map of the turbofan 20 engine was completed.

It's easier to say, but it's really drawn. It was a long and meticulous job, but even if it took a lot of time, Li Tianfeng was still ready to complete it himself.

With the 3D color map of the turbofan 20 engine, it can not only boost everyone's morale, but also let everyone have an intuitive understanding of this engine visually, and can also guide everyone in a series of design work.

Li Tianfeng was concentrating on drawing, and Liu Wei was happy. He walked in happily and said, "Boss, there's a fax from Embraer." Mr. Marceldo will lead a delegation to our company again for a business visit, boss, they must come to order engines this time. ”

Li Tianfeng couldn't help but smile when he saw Liu Wei's happy face, and then said, "Ignore them for now, and let them dry for two days." ”

"Ahh Liu Wei was stunned. didn't think about it, Li Tianfeng did this, all along, didn't Li Tianfeng want his engine to go abroad and open the international market. This is an opportunity to send it to the door, without thinking about it, Li Tianfeng has to dry the other party for two days.

However, Liu Wei quickly understood the reason, knowing that Li Tianfeng had an opinion on Embraer and wanted to take advantage of it to vent his anger.

Liu Wei said: "Boss, then we will dry them for two days first." ”

………

Embraer.

Marceldo finally breathed a sigh of relief and finally persuaded the entire board of directors, at the board of directors just now, Marceldo took a lot of pains, and even personally became a salesman for Tianfeng Technology Company.

Fortunately, Marceldo has a very good understanding of the turbofan 16, turbofan 17 and turbofan 18 engines of Tianfeng Technology Company, and is very well prepared.

Even, because Marceldo, a salesman, was too devoted, he was questioned by one of the directors, asking whether Marceldo had received the benefits of Tianfeng Technology Company, otherwise, how could he be so hardworking.

In the face of questioning, Marceldo could only explain, and introduced the engines of Tianfeng Technology Company in detail, listing the outstanding points one by one.

Whether it is the turbofan 16, turbofan 17, or turbofan 18 engine, its performance is very good and excellent, the only drawback is that it has not been verified by a long flight time, and its safety and reliability have to be tested by time.

The aero engine giants such as Pratt & Whitney, GE, and Rolls-Royce have produced and manufactured aero engines, and their cumulative flight time has reached a terrifying data after a long period of flight verification, which is incomparable to Tianfeng Technology Company.

On the board of directors, there are naturally many directors who take this to talk about it, believing that they are producing and manufacturing civil airliners, and safety must be put first, and they are cautious about the engines produced by Tianfeng Technology Company.

Marceldo seemed to be determined to be the first to eat crabs, and after a war of words on the board, he finally reluctantly persuaded most of the directors, which also made Marceldo's heart a little lighter.

No, as soon as the meeting ended, he immediately asked his assistant to send a fax to Tianfeng Technology Company, making it clear that he would lead a delegation to Tianfeng Technology Company again.

Even, Marcellor had already thought about it, and he had estimated the approximate production and manufacturing capacity of Tianfeng Technology Company in his heart, and a plan was quietly produced in Marcello's heart.

Marceldo thought to himself, even if he couldn't monopolize the engines of Tianfeng Technology, he couldn't let Bombardier easily purchase a large number of engines from Tianfeng Technology.

However, Marceldo soon found that the fax he had sent was completely like a mud cow in the sea, and there was no news at all, so that Marceldo, who was originally full of ambition and hope, suddenly felt a little bad.

"Joseph, is there still no news from Tianfeng Technology?"

Joseph said: "BOSS, it's been two days, and the other party hasn't had any response, and I've sent five faxes to the other party in two days according to your request, but there hasn't been any response." ”

Marcel said: "Check the office phone number of Tianfeng Technology Company, I will call it in person." ”

Joseph acted quickly, and soon dialed the office phone number of Tianfeng Technology Company and gave the phone to Mr. Marceldo.

On the other end of the phone, there was a very nice female voice, it was Liu Wei who answered the phone, and the call went directly to the administrative department of Tianfeng Technology Company.

Marceldo was slightly stunned, but he immediately knew that it was Liu Wei, last time in Tianfeng Technology Company, Liu Wei went to the airport to pick up Marceldo and his party, which was not a stranger.

Marcel said in English: "Ms. Liu Wei, we have sent a total of five faxes to your company, and you have not replied, I want to know the reason, and in addition, I want to talk to Mr. Li Tianfeng on the phone." ”

Liu Wei is also fluent in English, and the answer is not leaky, Liu Wei said: "Mr. Marceldo, I'm really sorry, we manage the fax of Xiao Yang these days off, these faxes I will take a look in person, in addition, our Mr. Li is on a business trip, it may take a few days to come back, after our Mr. Li comes back, I will report the situation to our Mr. Li." ”

Marceldo is not a fool, there is a reason that cannot be heard, what Xiao Yang asks for leave and no one cares about the fax machine, it is simply nonsense, as for whether Li Tianfeng is on a business trip, it should be basically fake.

Through this phone call, Marceldo knew the attitude of Tianfeng Technology Company, Marceldo sighed softly, and after hanging up the phone, Marceldo's expression was a little frustrated.

Joseph next to him said: "BOSS, it seems that the other party has an opinion on us!" ”

Marcel said: "Now think about it, the last time we did that, it was indeed a little later, Joseph, continue to send a fax to contact Tianfeng Technology Company tomorrow, the tone is sincere, after the other party has a reply, tell me immediately." ”

Joseph naturally nodded hurriedly.

………

Tianfeng Technology Company.

Li Tianfeng was listening to Liu Wei's report, where did Li Tianfeng have any business trips, and he has been staying in Tianfeng Technology Company for a period of time.

Liu Wei said: "Boss, just now Marceldo called in person and made it clear that he wanted to talk to you on the phone in person." ”

Li Tianfeng smiled and said, "It seems that this Marcel is really a little anxious." ”

Liu Wei said worriedly: "Boss, if we hang each other like this, will we anger each other and cause the other party to be angry and stop ordering our engines?" ”

Li Tianfeng smiled lightly and said: "This should not be the case, I have confidence in our engine, and the other party will definitely contact us again." ”

Liu Wei said: "Boss, if the other party contacts us again, will we reply to the other party immediately?" ”

Li Tianfeng said: "It has been two days for the other party, which is enough, if they send a fax again, you will reply to the other party, and we welcome them to come to our company again for business inspection." ”

Sure enough, coming out of Li Tianfeng's office and returning to his office, Liu Wei soon received a fax from Embraer, and the other party's tone was very sincere.
