After all kinds of personnel were arranged, Li Tianfeng also breathed a long sigh of relief, and his heart was relieved for a while, Tianfeng Technology Company, the number of employees has reached four or five hundred, and it finally looks like a large company.

"The annual bidding meeting of factory E is about to be held, and it seems that we have to get as much processing business back as possible, otherwise, so many new recruits will face a situation of shutdown and no work." Li Tianfeng thought in his heart.

At the bidding meeting of Factory E, Tianfeng Technology is determined to participate, and the goal is not small, and now that so many new employees have been recruited, Li Tianfeng's appetite has gradually increased, and he wants to win a lot of business.

In his office, he was thinking about the upcoming bidding, when there was a knock on the door, "knock, knock, knock", Li Tianfeng knew that it should be Liu Wei, the general manager of the administration department.

"Please come in!"

With Li Tianfeng's permission, Liu Wei gently pushed the door in and reported: "Boss, Deputy Chief Designer Sun Xiaoping is coming over soon." ”

Usually, Hu Xiao generally calls Li Tianfeng "boss", because Hu Xiao is used to such a title in American companies, and under the influence of Hu Xiao, Liu Wei and others also changed the name of Li Tianfeng to "boss", and Li Tianfeng obviously likes and accepts this title.

Li Tianfeng knew that Sun Xiaoping was going to come to him today, and in order to show politeness, Li Tianfeng had already sent out his company's Mercedes-Benz business car and took Sun Xiaoping over.

Li Tianfeng got up, "Let's go, let's go downstairs to greet Vice President Sun Xiaoping." ”

Now I am different from before in Factory E, and I must deal with all kinds of relationships, because I am starting a business now, all kinds of relationships, all kinds of resources are more important, and maintaining a good relationship with Sun Xiaoping is definitely only good for Li Tianfeng.

The reception matter belongs to the business scope of the Administration Department, so Liu Wei followed Li Tianfeng, and the two walked downstairs together, standing in front of the office building, waiting for Sun Xiaoping's arrival.

After only waiting for three or five minutes, a black Mercedes-Benz business car drove over slowly, stopped in front of the office building, the door opened, Sun Xiaoping got out of the car with a happy face, seeing this, Li Tianfeng hurriedly took a few steps to meet him.

"Mr. Sun, welcome, welcome!"

"Mr. Li, you're polite, you're so polite!"

After a few words of greeting between the two, Sun Xiaoping said: "Mr. Li, you are good here, if you don't come to see it in person, I can't believe that there is such a scale." ”

Hearing this, Li Tianfeng smiled slightly, "Mr. Sun, let's go, go to my office and sit down." ”

Sun Xiaoping came over this time, just to find Li Tianfeng to have something, and he was not polite, and said with a hearty smile: "Mr. Li, then disturb." ”

After speaking, Sun Xiaoping carried a large black bag of his own, followed behind Li Tianfeng, seeing this, Liu Wei hurriedly took Sun Xiaoping's big bag with a smile.

"Liu Wei, general manager of our administration department!" Li Tianfeng introduced with a smile.

Liu Wei hurriedly stretched out her little hand, shook hands with Sun Xiaoping, and said with a smile: "Mr. Sun, I often hear the boss talk about you." ”

Liu Wei is an eight-sided delicate character, and he is at ease with such a scene, and the atmosphere is very good, Liu Wei also gave his business card to Sun Xiaoping, Sun Xiaoping was also polite, and gave Liu Wei a business card, and the three of them entered the office building together, entered the elevator, and went upstairs.

Li Tianfeng's office.

After sitting down, he took a sip of the hot tea made by Liu Wei herself, and Sun Xiaoping said: "Mr. Li, your office is atmospheric enough, at least more than 100 square meters." ”

Li Tian and the others smiled slightly, "Mr. Sun, I came in person this time to design the fan blades of the turbofan B engine last time!" ”

"Mr. Li, you guessed half right." After speaking, Sun Xiaoping smiled and opened his black bag, and took out a lot of drawings and design materials from it, all about the fan blades of the subturbofan B engine. ”

On Li Tianfeng's wide desk, Sun Xiaoping spread out the design drawing of the first-stage fan blades of the turbofan B engine, which is a No. 1 drawing, which is relatively large, but fortunately, Li Tianfeng's desk is wide enough.

"Mr. Li, this is a new drawing of our design, which has been verified and tested, and the effect is very good, and the overall performance of the fan has increased by about 50%, which is a very remarkable achievement."

As soon as the words changed, Sun Xiaoping's face was full of gratitude: "Mr. Li, without your guidance last time, we would definitely not be able to design such advanced fan blades, thank you, thank you so much, the design results have been reported to the group company, if nothing else, it may win the second prize of this year's National Science and Technology Progress Award." ”

Second Prize of National Science and Technology Progress Award! This is quite an achievement.

"Mr. Sun, congratulations!." Li Tianfeng was also very happy.

"Where, where." Sun Xiaoping was very modest, "Mr. Li, if it weren't for your guidance, how could I, Sun Xiaoping, have the ability to design such an advanced wide-chord fan blade and break the gap in China in one fell swoop." ”

"Mr. Li, this is the first stage of fan blades we designed, you can take a look and see if there is still the possibility of improvement."

Sun Xiaoping is very modest, completely asking for advice, fortunately there is no third person here, Liu Wei has already closed the door and retreated, otherwise, seeing this scene, he will definitely be shocked, because Sun Xiaoping's identity is the deputy chief designer of the sixth institute and the chief designer of the engine model.

Seeing this large drawing, Li Tianfeng looked at it seriously, "Mr. Sun, it was completely designed according to my original ideas, it is very good, and there is no need to improve it at all." ”

Then, Li Tianfeng looked at the design drawings of the second-stage and third-stage fan blades one by one, and was quite satisfied, and only proposed a little bit of improvement, such a little bit of improvement, Sun Xiaoping took out a notebook and recorded it word for word.

After reading the drawings of these fan blades, Sun Xiaoping carefully folded these drawings and put them into his big black bag, and then, as if playing a trick, took out a large stack of drawings from it.

Seeing these drawings, Li Tianfeng was stunned for a moment, and thought to himself, what kind of drawings are these? Sun Xiaoping saw Li Tianfeng's puzzled expression, and couldn't help but smile embarrassedly: "Mr. Li, I want to ask you again this time." ”

Spread out these drawings, Li Tianfeng recognized them at a glance, it was actually the design drawings of the turboshaft C engine compressor part, no wonder Sun Xiaoping carried such a large black bag, it turned out that there were a lot of things in it.

Turboshaft C engine, Li Tianfeng is very familiar, when he was in the E factory before, Li Tianfeng also solved a lot of processing problems of key parts, otherwise, the turboshaft C engine does not want to develop so smoothly, it may also delay the National Day gift of the eleventh.

It is said that the turboshaft C engines produced by Plant E are equipped with the most similar armed helicopters in China, and they flew in formation over Tiananmen Square, becoming one of the biggest highlights of the National Day military parade, and the military even sent a commendation order to Factory E.

A total of nine people in E factory have been ceremoniously commended, these nine people are known as "National Day Meritorious Figures", if Li Tianfeng did not resign from E factory, he will definitely be commended, then the number of people who were commended in E factory is not nine, but ten.

As the design unit of the turboshaft C engine, several people have also been commended, and Sun Xiaoping, the chief designer of the model, is one of them.

"Mr. Sun, this is the design drawing of the compressor part of the turboshaft C engine." Li Tianfeng was slightly surprised, but he didn't think that Sun Xiaoping brought such a drawing.

The turboshaft C engine is divided into five parts, namely the compressor part, the combustion chamber part, the turbine part, the reducer part, and the accessory part. The compressor part is further divided into axial flow compressor and centrifugal compressor.

"Yes, Mr. Li, I brought the design drawings of the compressor part of the turboshaft C engine." Sun Xiaoping said.

Li Tianfeng said suspiciously: "Mr. Sun, hasn't the development and production of the turboshaft C engine always been relatively smooth, and it is also equipped with the most advanced armed helicopter in my country and participated in the high-profile National Day military parade." ”

"Hey!" Sun Xiaoping sighed and said: "Mr. Li, I won't tell you, the turboshaft C engine looks glamorous, but in fact, many problems have not been fundamentally solved. ”

"Oh, what's the problem?" Li Tianfeng was also interested.

Sun Xiaoping did not hide it, and said truthfully: "First of all, the efficiency of the compressor part is not high, compared with the same turboshaft engine in the United States, the efficiency of the compressor is at least one grade lower, the efficiency of the combustion chamber is not high, the fuel consumption is large, and the situation of the turbine part is even worse, one is that the temperature before the turbine can not be further improved, and the second is that the turbine blade life is not good, and it cannot withstand the higher temperature before the turbine......"

Sun Xiaoping said a lot of big problems, Li Tianfeng knows that if these problems are not solved, the turboshaft C engine may really become a flower in the mirror, the moon in the water, everyone has high hopes for this project, but it may have to be aborted, so many big problems are not solved, and it will not be possible to mass produce at all.

Even in mass production, there will be problems in the process of use, and after two or three hundred hours of use, an engine will face overhaul.

It takes two or three hundred hours to overhaul, which is a little too terrifying, military aircraft engines must be overhauled for at least 1,000 hours, and abroad, it has reached 3,000 hours, or 5,000 hours before overhauling, and even 8,000 hours before overhauling.

Two or three hundred hours to overhaul, that's too shocking!

Li Tianfeng began to ponder, and after thinking about it, Li Tianfeng said a little helplessly: "Mr. Sun, in such a situation, if you want to fundamentally solve the problem, you can only make a major change to the turboshaft C engine, or even tear it down and start over." ”

Overhaul! Tear it down and start over!

Hearing this, Sun Xiaoping's face was more depressed, and after a long time, Sun Xiaoping sighed, silently put away his drawings, there are so many big problems with the turboshaft C engine, Sun Xiaoping thinks that it is completely unnecessary to ask Li Tianfeng to improve the compressor part.

changed the compressor, the combustion chamber, the turbine, and the reducer, there are so many problems, Sun Xiaoping is embarrassed to trouble Li Tianfeng all the time, Li Tianfeng is not an employee of the Sixth Design Institute, and they don't have that obligation.
