Li Tianfeng thought for a while and said: "Grandpa Wang, I am confident that I will successfully develop the TFWZ001 turboshaft engine within three years, if I can develop it within three years, please allow me to be with Ruobing." “

Wang Guohong said: "What if it is not successfully developed within three years? ”

Li Tianfeng said firmly: "Sure, I have this confidence and certainty." ”

"Okay, I'd like to take a look, if you can really succeed in developing such an advanced turboshaft engine within three years, I will marry Ruobing to you, and I will bless you, but if you can't develop it within three years, young man, don't blame me for being ruthless."

"Okay, it's a deal!" Li Tianfeng said categorically.

"Okay, that's it!" Wang Guohong is also full of momentum.

Li Tianfeng was about to thank him, but he saw Wang Guohong say: "Young man, don't blame me for not reminding you, at present, our country has not fully opened the aviation industry market, your company, as a private enterprise, wants to obtain a production license, it is difficult to obtain an airworthiness certificate,"

Li Tianfeng said confidently: "Grandpa Wang, I also know this, I have my own way." ”

Things are basically done, although it is not very perfect, but it is also within Li Tianfeng's expectations, three years, Li Tianfeng can afford to wait, I believe Wang Ruobing can also afford to wait, Wang Ruobing is only 22 years old this year, and in another three years, he will only be 25 years old, and he is still very young.

"Grandpa Wang, thank you, I will definitely successfully develop this turboshaft engine." Li Tianfeng said.

Wang Guohong nodded, "Young man, it's good that you have this kind of confidence, I appreciate it, but I still have to remind you again, in the past three years." I won't provide you with any help, you can only rely on yourself, and in addition, you can't move around under the banner of our Wang family, and you can't pull relationships everywhere. ”

"That's natural." Li Tianfeng assured.

……

Although Wang Ruobing did not enter the study, he had been waiting anxiously for Li Tianfeng in the reception room. Seeing Li Tianfeng walk into the reception room, Wang Ruobing almost threw himself into Li Tianfeng's arms, and asked anxiously and worriedly, "Tianfeng, how is it?" ”

Li Tianfeng smiled with relief: "Ruobing, basically smooth." ”

Hearing this, Wang Ruobing's hanging heart was put down, and he breathed a long sigh of relief, and Li Tianfeng also explained the situation in detail.

"Tianfeng, it turns out that the satchel contains the information of the turboshaft engine. There are so many 3D color pictures, you are so smart, it's just, three years is not enough, in case the development fails, what should I do? ”

Li Tianfeng said confidently: "If there is no case, it will definitely succeed!" ”

Immediately, Wang Ruobing smiled.

………

Tianfeng Technology Company.

In your own office. Qiu Wenan is concentrating on the overall design of the fuel regulator of the "TFWZ001" turboshaft engine, including the basic structure. Basic components, basic parameters, and much more.

Aero engines, there must be a fuel regulator, in the engine control system, the fuel regulator is an important component, very important. Fuel regulator. Hence the name, it is to adjust the amount of aviation fuel, just like the accelerator of a car, as soon as you step on the accelerator, the horsepower of the car will come up.

It's just that. Fuel regulators are much more complex, much more demanding, and require very precise fuel regulation, involving a lot of cutting-edge design stuff.

Domestic aero engine, fuel regulator is basically mechanical, Li Tianfeng knows that this regulator has been relatively backward, can not adapt to the relatively advanced "TFWZ001" turboshaft engine, as the fourth generation of turboshaft engine, must use electronic digital fuel regulator.

This kind of fuel regulator design is a cutting-edge topic in China, and although Qiu Wenan has researched it, it is also the first time to carry out the design.

"It would be nice if the boss was at home, a lot of things are not accurate, and now I can't find someone to ask." Qiu Wen thought with peace of mind.

Sometimes, Qiu Wenan even thinks that in the design of aero engines, Li Tianfeng is the supreme god in his heart!

Li Tianfeng is not there, and some things are not accurate, Qiu Wenan can only build the overall framework of the fuel regulator design, and the temporary vacancy that is not accurate, is ready to convene Sun Xiaoping, Wu Shungao, and several senior engineers who are good at controlling the system design in the afternoon, and everyone will have a meeting to discuss, not to say that there are three stinkers and one Zhuge Liang.

In addition, the design of the lubricating oil system is also basically completed, you can also discuss it, Li Tianfeng is not there, we can only brainstorm, fortunately, the overall design scheme of the engine is designed by Li Tianfeng himself, there are specific parameters, we carry out the specific design according to these parameters, it is equivalent to having a guiding text, which is a lot more convenient.

Lubricating oil system, fuel system, are important systems of aero engines, and separate into a relatively independent system, fuel and lubricating oil must not be mixed together, fuel is fuel, lubricating oil is lubricating oil, no matter which system, in the design and very technical content.

All morning, Qiu Wenan was in his office, serious and careful to design the fuel regulator.

In the afternoon, Qiu Wenan convened a meeting in the small conference room of the Aero Engine Design Institute to discuss some key issues and some difficult problems in design.

The projector projects the overall design scheme of the entire fuel regulator, on the snow-white wall, clearly, everyone sits in the conference room, looks at the overall design scheme, thinks carefully, and gives full play to their intelligence and design level.

"Mr. Qiu, I see if the design of the fuel pump can be slightly improved to increase the fuel output of the fuel pump." A high engineer.

The fuel pump mainly pumps the fuel into the fuel system of the aero engine at a certain pressure, how big the pressure is, there are strict requirements, the big is not good, the small is not good, in addition, the fuel pump can pump how many liters of fuel can be pumped in a minute, in the design to be fully considered, of course, the fuel pump can be controlled, through the electronic induction, how much you want to pump in must be able to control how much you pump in.

The amount of fuel is directly related to the power output of the engine, more fuel, more power output, less fuel, small power output, as far as the engine is concerned, there is a rated output power state, there are 1.2 times the rated output power state, there are also 0.8 times the rated output power state, 0.5 times the rated output power state and so on.

When a helicopter is in normal flight, its engine is not the rated power output state we imagined, but often does not reach this range, and is often only a few tenths of a time of the rated output power state.

If a helicopter has two turboshaft engines, if one engine stops working, the other engine can cope with the emergency, and the output power of the remaining turboshaft engine can rise immediately, from a few tenths of a times the power, quickly climbing to 1.0 times or even 1.2 times the rated power state, that is to say, generally speaking, the helicopter equipped with two turboshaft engines is far safer and more reliable than the helicopter equipped with a turboshaft engine.

At the meeting, everyone gave full play to their professional knowledge, and some designs that were not accurate were finalized one by one, and even some improved designs were carried out.

Towards the end, Qiu Wenan breathed a sigh of relief, the overall design plan of the fuel regulator was finally finalized, and then as long as it was sent to Li Tianfeng for review and signing, further relevant designs could be carried out in detail according to this overall design plan.

In fact, Li Tianfeng has returned from the capital, and he is worried about his Tianfeng Technology Company, and when he returns to Songzhou, Li Tianfeng returned to the company non-stop, and he didn't have time to sit in his office, and immediately came to the aero engine design institute located in the technology center building.

In the past few days, he is not in the company, Li Tianfeng thought in his heart, I don't know if Qiu Wenan and others can provoke the beam, walked into the design office, looked at each floor, and saw that the designers were seriously carrying out the design work, Li Tianfeng was more satisfied.

Passing by the small conference room, he saw that the door of the conference room was empty, so Li Tianfeng pushed the door in, and saw that there were many people in the conference room, everyone was brainstorming and discussing the overall design plan of the fuel regulator.

Obviously, everyone saw Li Tianfeng, and Qiu Wenan also saw Li Tianfeng, and there was a slight excitement in his heart, "Boss, are you back?" ”

Li Tianfeng smiled and said, "Just come back, you continue, I'll just listen to it." ”

Sun Xiaoping said: "Boss, do you have any instructions?" ”

Li Tianfeng shook his head, "You go on, I don't have any instructions for the time being." ”

Seeing this, Qiu Wenan discussed the basic design parameters of the fuel regulator with everyone, and then talked about the overall design scheme of the fuel regulator in general, including structural design, performance design, design parameters and so on.

Li Tianfeng listened carefully, and after listening to it, Li Tianfeng frowned slightly, Sun Xiaoping observed more carefully, and clearly captured this little change in Li Tianfeng, so he gently pulled Qiu Wenan and said softly in Qiu Wenan's ear.

Qiu Wenan looked at Li Tianfeng, and sure enough, seeing Li Tianfeng's brows frowning slightly, he couldn't help but sigh in his heart, and thought in his heart, is there something wrong with this design?

………

Today, the third watch will continue, and the third watch will be sent!!

In the description of the protagonist's feelings, some people may feel that it is more unsuccessful, but there is a reason for this, laying the groundwork for the development of the storyline in the future, of course, as an industrial text, the emotional description is not the main line, and the proportion of follow-up in this area will be very small, focusing on the development of aero engines, on this road, try to break out all kinds of hardships and all kinds of cool points one by one.

After a training in Guangzhou, I think I have gained a lot, especially the series of writing techniques that Xuehong said, and Beike will use this harvest in the follow-up writing one by one, striving to be wonderful and satisfying everyone.
