Tianfeng Technology Company.

Li Tianfeng was looking at an album of his first turbofan engine, which was prepared for the Zhuhai Air Show in November this year.

Thinking of the last air show two years ago, Li Tianfeng still remembers vividly, the original Tianfeng Technology Company was established only for more than a year, and there is no aero engine that can be used, and the original vortex D is still in the design stage, and there is no physical object.

Two years later, the turboshaft D engine was already mass-produced, and the turboshaft E engine also had a good customer and began mass production.

In addition, one of its turbofan engines is nearing the end of design and has begun to enter the stage of trial production of parts, and the design of a second turbofan engine has already begun.

In Li Tianfeng's view, the current Tianfeng Technology Company has a bit of a feeling of changing a shotgun for a cannon, and finally has something to do.

The turboshaft E engine will definitely be exhibited, and the turboshaft D engine will be exhibited because it is for the military, so it will have to apply for approval if it participates in the exhibition, and in addition, its first turbo engine will definitely be exhibited.

You may wonder how this engine is only in the trial production stage of parts, so how can it be exhibited.

In fact, this is possible, and there is a precedent in the international arena for a long time. As long as the engine can be assembled, such an engine may not be able to work and perform up to standard, because the parts are not verified, such an engine, just assembled, the appearance looks the same as the official real engine, at least the appearance looks exactly the same.

Such an engine is only used for the exhibition, and at the end of the exhibition, the engine has completed its historical mission, which is also called the "exhibition machine", as the name suggests. It is the engine that participates in the air show.

Sun Kang is in charge of the company's production, and at this moment, in Li Tianfeng's office, the two are discussing the assembly of the exhibition machine.

Sun Kang said: "Tianfeng, if you install an exhibition machine, it is not a big problem. There are basically all major parts, and some invisible small parts can not be installed, and the problem is not big. It's just that if you want to install two, it's a little difficult, and some parts are missing. ”

Li Tianfeng said: "I have great hopes for this air show, and I must install two exhibitors, one of which is a quarter cutting machine. ”

The so-called "quarter cutter". It is based on the central axis of the engine, cutting a quarter to expose the internal structure of the engine, so that you can see the details of the engine more clearly, especially some internal details.

Seeing that Li Tianfeng was so resolute, Sun Kang nodded and said, "Then we will go all out, even if we work overtime, we must produce all the missing parts." ”

Li Tianfeng nodded and said, "Brother-in-law." Although the parts do not need to be verified, they can be installed directly. However, the quality of parts, especially the appearance quality, must be paid attention to, and it must not be rough. ”

Sun Kang also knows this, because these two exhibitors are going to participate in the air show, that is, for others to visit. The appearance quality must not be bad, on the contrary, the appearance should be of high standards and high requirements.

After discussing the matter of the two exhibitors with Sun Kang in his office for a long time, he sent Sun Kang away. Li Tianfeng called Sun Xiaoping over again.

Li Tianfeng asked: "Mr. Sun, how is the design outline of our 'TFWZ002' turbofan engine?" ”

The 'TFWZ002' turbofan engine is the second turbofan engine, and the first turbofan engine is the 'TFWZ001' turbofan engine, both of which are in-house models of Tianfeng Technology.

Later, after the formal design is finalized, the engine will be a turbofan XX engine.

Sun Xiaoping said: "Boss, it's basically almost finished." ”

Li Tianfeng nodded: "Mr. Sun, I will give you another task, arrange a few elite soldiers and strong generals, and draw a 3D color map of our 'TFWZ002' turbofan engine, not only to have an overall drawing, but also to have a component drawing, the more exquisite the drawing, the better." ”

Sun Xiaoping quickly understood what Li Tianfeng meant, and immediately said: "Boss, this is to prepare for participating in this year's Zhuhai Air Show, participating in the air show is a big thing for our company, and I will definitely draw it as required." ”

Li Tianfeng nodded, and then asked about some things about the engine design......

…………

Sun Xiaoping's efficiency is still okay, and in less than ten days, the 3D color map of the 'TFWZ002' turbofan engine has been drawn.

Although it was drawn using drawing software, it looks very close to the real thing, and if you don't look closely, you will think that it is a color photo of a real aircraft engine.

In addition to the overall color map, there are also parts color map, such as fans, compressors, combustion chambers, turbines, etc., these parts color maps, all cut drawings, such as the fan part, are cut symmetrically from the central axis, like a watermelon cut in half.

The purpose of this is naturally to show it more clearly, and it looks very exquisite, as for not worrying about causing technical leaks, Li Tianfeng is not worried about this.

It's just a color picture, no size, no technical conditions, how to talk about leaks!

After reading these 3D color pictures, Li Tianfeng was very satisfied, with these color pictures, he could make a good color brochure for this turbofan engine with a thrust level of 20,000 pounds.

In addition to the 3D color drawing, the design team led by Sun Xiaoping also completed the preparation of the design outline of the TFWZ002' turbofan engine.

At present, Sun Xiaoping's design team can carry out the design of this turbofan engine according to the design outline, and the design work has begun according to Li Tianfeng's requirements.

The core machine does not need to be redesigned, but only on the basis of the existing core machine, the design difficulty will be much lower, which is why Li Tianfeng originally promised Shen Wensheng to tailor a turbofan engine for the Xiang-Feng regional airliner.

In fact, the thrust level of 20,000 pounds is the fourth-generation turbofan engine, and the comprehensive performance is so excellent.

After reading these 3D color pictures, Li Tianfeng was very satisfied, and was about to call Sun Xiaoping to praise him, when Li Tianfeng's mobile phone rang.

Seeing that the caller ID was Shen Wensheng, Li Tianfeng smiled, Shen Wensheng promised that he would report to his chairman after he went back, and thought in his heart, is there a result.

Li Tianfeng said happily: "Mr. Shen, how is the situation?" ”

Surprisingly, Shen Wensheng sighed, "Hey, Mr. Li, I'm really sorry, our chairman is skeptical of your engine, I have communicated with our chairman several times, but I have not been able to change our chairman's attitude." ”

In fact, there is another point that Shen Wensheng did not say, that is, there is also Vice President Na Ding in the middle, who is a hindrance, so that Ma Delong is more doubtful about the performance of the two turbofan engines of Tianfeng Technology Company.

Li Tianfeng said: "Mr. Shen, there will be such a situation, but I never thought about it." ”

Shen Wensheng said apologetically: "Mr. Li, it takes a lot of manpower and material resources to develop an aero engine, you tailor a turbofan engine for our regional airliner, in case our chairman does not agree, your loss will be relatively large, Mr. Li, is it ......?"

Of course, Li Tianfeng knew what Shen Wensheng meant, and Li Tianfeng said: "Mr. Shen, no matter whether you will purchase our 'TFWS002' turbofan engine in the end, our company will also develop this turbofan engine." ”

An excellent turbine engine, in Li Tianfeng's view, must not worry about the market, this engine must be developed.

Both engines are developed at the same time, a thrust grade of 50,000 pounds, the other thrust grade of 20,000 pounds, if a thrust grade of 100,000 large turbofan engines are developed in the future, then the civilian turbofan market is very competitive, because of the wide coverage, the variety is relatively complete.

Zhang San doesn't want it, Li Si will always want it, such an engine should not worry about buyers, a turbofan engine with a thrust of 20,000 pounds, Li Tianfeng must develop it.

So, Li Tianfeng said: "Mr. Shen, thank you for your kindness, in addition, you will definitely participate in the Zhuhai Air Show, and then bring your chairman to our Tianfeng Technology Company's booth to have a look." ”

Shen Wensheng sighed slightly, "Mr. Li, I'm really sorry that things are like this, when the air show comes, we must come to your booth to take a look." ”

ended the call with Shen Wensheng, Li Tianfeng's face gradually became firm, he didn't believe in his technical strength, and he actually doubted that he could develop a fourth-generation turbofan engine with excellent performance.

Tianfeng Technology Co., Ltd., absolutely can!

I thought about it for a long time in my heart, and at the same time, Li Tianfeng secretly cheered for myself, clenched his fists, and said loudly in his heart, Li Tianfeng, work hard, work hard, and work hard, we must develop these two turbofan engines.

…………

As time went by, the time had come to the end of October, and the day of the air show was getting closer and closer.

Final assembly workshop.

Li Tianfeng, Sun Xiaoping and a large group of people were gathered in front of an aero engine, and everyone was happy, as if they had done a big thing.

Liu Wei next to her, still holding a camera in her hand, seemed to be ready to take pictures, and in the distance, many employees in the assembly workshop stretched out their necks and looked at this side curiously.
