Seeing that everyone's eyes were focused on him, Li Tianfeng smiled slightly.

Liu Qingshan naturally knew Li Tianfeng, and now seeing Li Tianfeng speak, Liu Qingshan himself didn't figure it out, and he suddenly had an expectation in his heart, expecting Li Tianfeng to be a blockbuster. Chief Engineer Yang Xianfeng was also deeply impressed by Li Tianfeng, and said in a very calm tone: "Xiao Li, you can talk about it, speak freely, don't have any worries." ”

Li Tianfeng smiled gratefully, and then continued: "Hello Mr. Yang, hello leaders and colleagues, fortunately, the turbine rotor of our turboshaft C engine was stuck during the assembly process, otherwise, there would be a big problem." ”

As soon as these words came out, many people were shocked, and many old comrades secretly shook their heads, thinking in their hearts, after all, they are young people, too young, and there is no one to speak, and such words can be said.

Li Tianfeng ignored everyone's puzzled gazes and continued: "It is precisely because of the sluggishness of the turbine rotor that I calculated a little just now, and this calculation is a big problem, and there is a big problem in the design. ”

Hearing this, everyone was shocked and thought to themselves, is there really a big problem with the design? No way!

Several design directors of the design institute looked at Li Tianfeng angrily, and now they are talking about design problems, which is equivalent to slapping the face of the design institute, that is, Sun Xiaoping, the chief designer of this model is also staring, looking at Li Tianfeng with blazing eyes, looking at this posture, if Li Tianfeng can't say a reason to come out, then he will be mad.

Li Tianfeng seemed to be full of confidence, and continued to affirm: "I must have a problem with the design, of course, there is also a problem with the manufacturing and assembly of the turbine rotor stuck in the machine, I will talk about this problem later, I will talk about the design problem first......

Li Tianfeng said very carefully, not only said the design structure, but also calculated, and even walked to the blackboard in front of the conference room in the eyes of everyone, picked up a pen and drew a rough diagram, and then sprinkled a large list of calculation formulas.

Most people can't understand these calculation formulas, and a small number of people can only understand a rough idea, and some of the formulas involved in them have never been seen by everyone, but everyone knows that these formulas are definitely not made up by Li Tianfeng, they must be true.

"As we all know, the outer diameter of our turbine rotor blades and the outer ring of the turbine have a matching gap, this gap is designed to be 0.1 to 0.15, everyone, this is only the clearance at room temperature, and when the turbine works, it will expand and contract, this is the result of my calculation, it can be seen from the calculation, even if our parts are all qualified, all meet the design size, but in the working high temperature state, the turbine rotor blades will still be scratched with the turbine outer ring."

Yan zhòng scratch!

This is terrible, such a high speed, once a strict scratch occurs, the turbine part will be scrapped, no, I am afraid that the entire engine will be scrapped, this, this, many people's heads are basically cold sweat out.

Sun Xiaoping, as the chief designer of the model, still has two brushes, and when he designed it, he naturally did calculations on thermal expansion and cold contraction, but there was a difference between his own calculations and Li Tianfeng's calculations, and now, after reading Li Tianfeng's calculations, Sun Xiaoping felt that he should have miscalculated.

Sun Xiaoping also basically understood Li Tianfeng's series of calculations just now, although there are some formulas that he has not been exposed to before, and they seem to be very complicated, but the results are there, and Sun Xiaoping believes it.

So, Sun Xiaoping's attitude changed 180 degrees, and he immediately said with emotion: "This comrade, now I am open, thank you, thank you!" ”

The people in the entire conference room were shocked when they saw Sun Xiaoping thanking him, and their eyes gradually changed when they saw Li Tianfeng.

Li Tianfeng was also generous, smiled lightly, and then continued: "Now let's talk about the problem of rotor stuckness, I also thought about this problem just now, our manufacturing and assembly have certain problems, to solve this problem, I think it is necessary to ......."

Li Tianfeng spoke for several more minutes, and said it in the same detail, many people immediately understood what the problem was, and some people thought that they had just spoken and expressed their own opinions, but they found that they were very different from Li Tianfeng, and their old faces suddenly turned red.

After Li Tianfeng finished speaking, the entire conference room was quiet, and everyone was basically shocked, and everyone thought in their hearts, it turned out that the problem was like this.

"Yes, yes, yes." Yang Xianfeng said two "good" words in a row, and then took the lead in applauding, and suddenly, everyone also reacted, and the whole conference room applauded like thunder.

Outside the conference room, two staff members have been on standby outside, as soon as they heard this warm applause, the two looked at each other, and both saw each other's doubts, the two have been working here for some years, but it is really rare to see such a thunderous applause as today.

The warm applause lasted for more than a minute, and the protagonist Li Tianfeng's heart was also full of joy, he didn't expect that he would be recognized by so many people at once.

Cheng Gang's face was happy, but he didn't think that Li Tianfeng was really a blockbuster, which was eye-opening, of course, Cheng Gang himself could be regarded as having opened a glimpse, and he calculated it like this.

glanced at Li Tianfeng approvingly, and now Cheng Gang found that no matter how he looked at it, he liked Li Tianfeng in his heart. Talents, talents, very rare talents, Cheng Gang thought in his heart.

The applause gradually stopped, Liu Qingshan also glanced at Li Tianfeng happily, motioned for Li Tianfeng to sit down, and then continued: "Let's discuss the assembly beating of the combustion chamber below, the comrades of the assembly workshop have introduced that in the assembly process, the beating of several key places in the combustion chamber can not meet the standard, and there is an outer circle surface that is even more outrageous to reach nearly 20 threads. ”

This time, everyone's speeches were much more cautious, obviously they didn't dare to make an axe, and a few people even took a special look at Li Tianfeng before expressing their opinions, and then carefully expressed their views.

Seeing this, Li Tianfeng couldn't help but shake his head helplessly, and thought in his heart, could it be that he was too good just now, giving everyone a lot of pressure. You know, just now I was just a small test, and I didn't show my real strength at all.

If everyone knows that Li Tianfeng thinks so, many people will definitely look up to the sky and sigh, just a small test of the knife shows such a strong strength, do you want people to live!

Seeing that everyone was speaking cautiously, Liu Qingshan had to say again: "Don't be pressured, don't be pressured, speak freely, I said it, even if it's wrong, it doesn't matter." ”

Even if Liu Qingshan said this, everyone still seemed cautious, and after saying something in twos and threes, no one stood up to express their opinions and opinions anymore.

Seeing this, Liu Qingshan and Yang Xianfeng glanced at each other, Yang Xianfeng nodded gently, Liu Qingshan understood, so Liu Qingshan personally nodded.

"Xiao Li, Li said his opinion."

Seeing this, Li Tianfeng stood up and said modestly: "Mr. Liu, then I'll say it casually, don't criticize me if you say something wrong." ”

"Haha, don't worry, just say it." Liu Qingshan is happy.

Seeing Li Tianfeng stand up, suddenly, the entire conference room immediately quieted down, everyone's eyes all looked at Li Tianfeng, and many people's eyes were full of expectation, looking forward to Li Tianfeng expressing his new views.

Clearing his throat, Li Tianfeng said: "The combustion chamber is a very important component of an engine, a good combustion chamber can not only give full play to the efficiency of fuel, but also provide a stable temperature field, just now I analyzed, our vortex C combustion chamber has the problem of runout out-of-tolerance, I think the root of the problem lies in the processing, in addition, there are problems with assembly." ”

"Yes, the flame cylinder part of this combustion chamber is allowed to give way, and the quality must be a little worse." Liu Qingshan Road.

The so-called concession release is that the quality of the parts does not meet the requirements of the drawings, but the parts are urgently needed for various reasons and have to be used, which is the concession release, which is also a helpless move.

Li Tianfeng nodded and continued: "There must be a part of the impact of the concession and release of parts, but I think the main problem lies in ......."

Li Tianfeng has said it for a long time, and what he said is also very detailed, many people suddenly realized, and thought in their hearts, it turns out that the problem is here, why didn't I think about it?

"Xiao Li, yes, yes, I think this is also the root of the problem." Yang Xianfeng personally spoke, agreeing with Li Tianfeng's point of view.

Seeing Mr. Yang speak, everyone was shocked again, many people admired Li Tianfeng a little, such a complex problem, Li Tianfeng can find the root of the problem, what is valuable is that Li Tianfeng also came up with a reasonable and effective solution.

This failure analysis meeting, because of Li Tianfeng's appearance, ended successfully, and a series of problems were solved one by one, Yang Xianfeng was very satisfied and in a good mood.

"Now the meeting is adjourned, by the way, Xiao Li, you stay for the time being."

Hearing this, everyone was envious for a while, but they didn't think about it, Mr. Yang left Li Tianfeng alone, who is Yang Xianfeng, the deputy general manager and chief engineer of Factory E, and the No. 3 person in Factory E.

Gently patted Li Tianfeng's shoulder, and glanced at Li Tianfeng approvingly, Cheng Gang thought in his heart, the young man can be favored by Mr. Yang, and the future is immeasurable!

Soon, the people in the conference room walked cleanly, leaving Yang Xianfeng, Liu Qingshan, and Li Tianfeng, Yang Xianfeng stood up and said, "Let's go, let's go to my office together, Qingshan, you also come together." ”
