Entering Li Tianfeng's office, Liu Wei said happily: "Boss, Embraer really sent a fax again, you see." ”

After speaking, Liu Wei handed the fax she had just received to Li Tianfeng, this was an English fax, Li Tianfeng was full of joy after looking at it for a while, Li Tianfeng said: "I can't see it, Embraer's attitude is quite sincere." ”

Liu Wei smiled.

Li Tianfeng said: "Mr. Liu, for the sake of their good attitude, give them a reply and welcome Comrade Marceldo to our company for a business visit." ”

Hearing this, Liu Wei smiled again, and then happily walked out of Li Tianfeng's office, looking at Liu Wei's happy appearance, Li Tianfeng also smiled, the peak turned around!

There are no eternal friends, only eternal interests, which Li Tianfeng has a deep experience, especially in the shopping mall.

The little dissatisfaction with Embraer, after two days of drying the other party, gradually disappeared, at this moment, Li Tianfeng's heart was thinking about the business visit that Marcel and his party were about to come over.

………

Embraer.

Marceldo has been waiting for Tianfeng Technology's reply, and has been hung by Tianfeng Technology for two days in a row, and Marceldo is really worried that Tianfeng Technology will form a cooperative relationship with Bombardier.

In his office, Marcel walked back and forth, looking anxious.

Just as Marceldo wanted to ask about the situation in person, the door to his office was pushed open. I didn't even knock on the door, but I saw my assistant rush in, and said happily and loudly: "BOSS." Good news, Tianfeng Technology Company has finally replied! ”

Hearing this, Marcel Duo was overjoyed in his heart, and he didn t care that his assistant rushed in without knocking on the door, Marcel Duo snatched this fax of Tianfeng Technology Company's reply, and hurriedly glanced at it, and then. He was so happy!

"Joseph, quick, quick. Book your ticket now and we'll be leaving tomorrow! ”

…………

Tianfeng Technology Company.

Li Tianfeng watched Liu Wei happily walk out of his office, and smiled happily, at this time. Xu Lilong's long-distance call came.

Xu Lilong said: "Boss." The good news is that Bombardier has made it clear that after our turbofan 17 engine completes a series of verification flights, Mr. Smith will personally lead a delegation to our company to negotiate the order of the engine. ”

Hearing this, Li Tianfeng was overjoyed in his heart, today is really an auspicious day, and this good news is really one after another.

Li Tianfeng said: "Mr. Xu, you have worked hard. We are very pleased to welcome Mr. Smith to visit us, Mr. Xu. You are indispensable! ”

Xu Lilong was also very happy, "Boss, this trip to Canada is relatively smooth, our turbofan 17 engine series of test flights have performed well, I feel face-saving in front of these foreigners, two days later, I will lead the team back." ”

Li Tianfeng said: "Mr. Xu, you can play in Canada for a few more days and relax." ”

Xu Lilong said: "Thank you boss, I know that the company must have a big mess, and I have wanted to come back for a long time." ”

Li Tianfeng smiled, Xu Lilong's professionalism, Li Tianfeng felt very satisfied.

Xu Lilong will return to the company, Li Tianfeng will not be so busy, more energy will be focused on the research and development of the turbofan 20 engine, since learning that Wu Lao went out of the mountain and presided over the development of the turbofan 19 engine, Li Tianfeng obviously felt the pressure.

Li Tianfeng thought in his heart, the turbofan 20 engine is the first military turbofan engine of Tianfeng Technology Company, which can only succeed, not fail!

Thinking about the development of the turbofan 20 engine, Li Tianfeng got up, left his office, and went to the aero engine research and development center.

Li Tianfeng listened to the reports of Sun Xiaoping and Qiu Wenan, and personally went to the design offices of his subordinates to see the design progress of the turbofan 20 engine.

At present, in the aero engine R&D center, the design of the turbofan 20 engine is the top priority.

A design room is generally responsible for the design of a certain component of an aero engine, such as the fourth design room is responsible for the design of the turbine part, and the fifth design room is responsible for the design of the combustion chamber part.

Aero engine R&D center, a total of nearly 3,000 technicians, including hundreds of senior titles, this is a strong design team, Li Tianfeng looked at it, his heart is very satisfied.

In the second design room, Li Tianfeng saw several designers discussing the design of the fan casing, obviously, there was a technical controversy.

Coincidentally, Li Tianfeng and Sun Xiaoping walked into the second design room, and happened to see that these designers were arguing, and their faces were red, seeing this, Li Tianfeng and Sun Xiaoping looked at each other and smiled, such a design technical controversy is completely allowed in Tianfeng Technology Company.

The more the reason is argued, the more the reason is clearer, the same is true in the design of aero engines, and the debate on the design technology of aero engines is basically a tradition in Tianfeng Technology Company.

Seeing Li Tianfeng, these technicians immediately stopped, and seeing this, Li Tianfeng said in a calm tone: "It's okay, you discuss yours." ”

One of the designers, who seems to be not old, Li Tianfeng has the impression that one of the chief designers of the second design room, has a very high level of design, surnamed Ye, was a senior engineer of a domestic aero engine design institute, and joined Tianfeng Technology Company two years ago.

Ye Gong said: "Mr. Li, we have a dispute about the design of this fan shaft, we have a dispute about the strength calculation, you can help us take a look." ”

The fan shaft of the turbofan 20 engine is the key part, and it is also the main force part, and the strength calculation is very important and critical. The fan shaft of the turbofan 20 engine is designed on the basis of the fan shaft of the turbofan 16 engine, and the structure is basically similar, but there are certain changes.

Li Tianfeng didn't shirk, walked over and asked, "Ye Gong, how did you calculate?" ”

Ye Gong said: "Mr. Li, I calculated it manually by myself, and Zhang Gong used the force software to analyze the conclusions. ”

Li Tianfeng carefully looked at the respective calculation methods and calculation results of Ye Gong and Zhang Gong, and then said: "Both of you have a little problem with the calculation, Ye Gong, there is a little problem with your calculation formula and method, Zhang Gong, when you use the force software to analyze, the parameter input is wrong." ”

After speaking, Li Tianfeng personally sat in front of the computer, and said while entering the parameters on the force analysis software: "Zhang Gong, this is finite element analysis, the parameters should be like this, you see that this parameter 41.25 should be 41.15, and this outer diameter parameter should also be changed......"

Li Tianfeng personally modified the parameters slightly, and then, the analysis results came out quickly, which was a little different from what Zhang Gong analyzed just now.

Zhang Gong looked at it seriously, and after looking at it, Zhang Gong said with admiration: "Mr. Li, it's really like this, I really had a problem with the input of these parameters just now." ”

Li Tianfeng nodded, then took a piece of white paper, Sun Xiaoping hurriedly gave Li Tianfeng a pen, Li Tianfeng took the pen and paper, listed a long list of formulas on the white paper, and then said: "Ye Gong, the force analysis should be carried out like this, you see ......"

While speaking, Li Tianfeng was calculating quickly, and even, a designer next to him gave Li Tianfeng a calculator, Li Tianfeng gently pushed it away, and he didn't need a calculator at all.

A piece of white paper the size of A4 was quickly filled by Li Tianfeng, and while calculating, Li Tianfeng also said, why is this so, and the result is calculated, which is consistent with the results of the computer analysis just now.

Looking at Li Tianfeng's calculations and listening to Li Tianfeng's explanation, Ye Gong finally understood, and hurriedly nodded: "Mr. Li, this is really the case, my calculation just now is really a little improper." ”

Li Tianfeng patted Ye Gong's shoulder gently, "Ye Gong, you must get used to using a computer for analysis, manual calculations will inevitably make mistakes, so try to use them sparingly." ”

Li Tianfeng could see that Ye Gong was relatively old, and he definitely didn't have a computer when he was in college, and he was used to manual calculations.

In terms of the level of manual calculation, Li Tianfeng asked himself that no one in the entire Tianfeng Technology Company can be beaten, but there is an advanced tool such as a computer, and the force analysis software is becoming more and more advanced, so it is better to use this tool.

Ye Gong is in his forties, and in recent years, he has been working hard to learn and use computers, and after hearing Li Tianfeng's words, Ye Gong nodded: "Mr. Li, I will remember your words and try to use computer-aided design and calculation in the future." ”

"Hmm." Li Tianfeng nodded a little satisfied, then took a look at the second design room, and left satisfied.

After Li Tianfeng left, many designers in the second design room surrounded him, and some people even said: "Ye Gong, our Mr. Li is so powerful, how complicated the force analysis of the fan shaft is, it can be calculated by hand." ”

"Our Mr. Li's technical calculation level is also very high, you didn't find out how skilled Li was when he always used computer software to perform force analysis just now, admire!"

"Sure enough, it's true, the rumors that Mr. Li is very skilled, I never believed it before, and now it seems that the rumors are not wrong at all."

“……”

Hearing the surprise and admiration of the designers around him, Ye Gong took the A4 blank paper that Li Tianfeng had written full of calculation formulas just now, and thought in his heart, it seems that compared with Mr. Li, the difference in technology is still very huge, and he has to continue to work hard.

For a long time, Ye Gong asked himself to have more than 20 years of experience in aero engine design, and he is a senior engineer, and he is a little proud of his technology.

"Well, in the future, I will work hard to improve my design business level and try to narrow the gap with Mr. Li." Ye Gong thought resolutely in his heart.
