There is nothing wrong with status determining treatment. Now Tianfeng Technology Company has more than 10,000 employees, an area of more than 2,000 acres, last year's annual output value was more than 20 billion, this year's annual output value is not to mention doubled, an increase of at least 50%.

In addition, the turboshaft D and turboshaft E engines are excellent, especially won wide praise from the military, and the children of the Wang family are in the army, and they know the excellence and excellence of these two engines. In addition, the design of the turbofan 16 is finalized, and everyone is polite to Li Tianfeng, especially the elders are good to Li Tianfeng.

The birthday banquet is a family banquet, there are basically no outsiders to attend, and the atmosphere of the banquet is relaxed.

The day after the birthday banquet, Wang Ruobing's grandfather Wang Guohong really saw Tianfeng, when Li Tianfeng was talking and laughing with the third generation of the Wang family in the living room, Wang Ruobing came over and said: "Tianfeng, grandpa asked you to go to the study, I have something to talk to you about." ”

The third generation of the Wang family was slightly stunned, and then looked at Li Tianfeng with envy, in everyone's memory, it is relatively rare for his grandfather to call himself into the study so formally, and there have only been a few times over the years.

In the envious eyes of everyone, Li Tianfeng and Wang Ruobing walked towards the backyard one after the other, the mansion was in and out a few times, it was relatively large, Wang Guohong's study was in the quiet backyard, and Li Tianfeng had also been to this study several times.

"Tianfeng, grandpa is already inside, you go in, I'll wait for you outside."

Li Tianfeng said: "You go to play with everyone, Ruobing, it's none of my business." ”

After speaking, he gave Wang Ruobing a "you can rest assured" look, Li Tianfeng knew that Wang Ruobing must be worried about himself. Wang Guohong's majesty, not to mention the third generation of the Wang family like Wang Ruobing, even if it is the second generation of the Wang family, it is also deep-rooted.

After Li Tianfeng gave Wang Ruobing a look, he knocked on the door gently, and heard a sound of "come in" from inside. Li Tianfeng tidied up his appearance a little and walked in.

Wang Guohong has been in a high position all the year round, that kind of invisible momentum and majesty, to be honest, Li Tianfeng was also slightly nervous in his heart, but unexpectedly, Wang Guohong's complexion was very peaceful.

Wang Guohong said: "Tianfeng, come and sit." If you drink tea, pour it yourself, don't be nervous, today our grandfather and grandson are just chatting normally. ”

Li Tianfeng hurriedly said: "Grandpa, I'm not thirsty, I was chatting with everyone outside just now, and I have already drunk tea." ”

Wang Guohong smiled kindly, it was completely a homely chat, and asked Li Tianfeng a lot of things in his work and life. Li Tianfeng answered truthfully one by one.

After asking a lot of things, Wang Guohong said: "Tianfeng." Listening to the reaction of the troops, the turboshaft D and turboshaft E engines produced by you are very good, and the evaluation of the troops is very high. ”

Li Tianfeng smiled proudly and said: "Grandpa, these two engines are fourth-generation turboshaft engines, and the power-to-weight ratio reaches ten, and the comprehensive performance is also good." ”

Wang Guohong nodded and said, "Tianfeng." You must know better than me about the current situation of the domestic aviation industry, because we started late, the basic industry is weak, and now the level of our aviation industry is at least more than 20 years behind the developed countries in the West, and we have a long way to go! ”

After a slight sigh. "Our troops need advanced and excellent aviation equipment, and many comrades in the army often mentioned this when they reported to me, because a country as big as ours must be a military power and need advanced aero engines, and we can't test every new aircraft with imported engines......

Wang Guohong seemed to be very touched, and talked a lot about the situation of the domestic aviation industry, as well as the situation of the army's aviation equipment.

Wang Guohong said: "Tianfeng, your turbofan 16 has been designed and finalized, and the military has also ordered it, which I am very pleased with, but I know that the military must still urgently need advanced small channel ratio turbofan engines, if you have the ability, you can carry out research in this area." ”

Because of the large windward area, the turbofan generally flies at subsonic speed, and the cruising speed is generally about Mach 0.8, emphasizing economy, comfort, low noise, low fuel consumption, low emissions, high reliability and safety.

Such turbofan engines are generally used in civilian airliners, and in the case of the military, they are generally used in transport aircraft and bombers, because such large aircraft do not need to fly at supersonic speeds, rely on low fuel consumption, and obtain a longer range.

Small signal than turbofan engine, because of the small windward area, strong thrust, generally military, and installed in advanced fighters, emphasizing supersonic cruise, strong thrust, speed, high reliability and safety in the first place, economy, comfort, low noise in the second place, of course, low fuel consumption is also to try to consider.

The lower the fuel consumption, the same fuel means that the fighter can fly farther and have a larger combat radius.

In the early stage of supersonic fighters, turbojet engines were generally used, but this kind of engine, with high fuel consumption, is simply an oil tiger, because in this way, lower fuel consumption, the windward area is also relatively small, and the small channel ratio turbofan engine that can achieve the same thrust gradually replaces the turbojet engine.

There must have been comrades in the army who reported to Wang Guohong, otherwise, Wang Guohong would not have mentioned to Li Tianfeng about the turbofan engine of Xiaohan Daobi.

Wang Guohong said: "Tianfeng, although our J-10 engine has been made in China, but the engine is the third generation of the machine, and the fourth-generation Xiaohan Dao is more than the turbofan engine There is a big gap, in addition, our J-20 has been successfully test-flown but it is an excellent engine, if you can, you can carry out research in this area." ”

Li Tianfeng knew that Wang Guohong proposed this matter, and it was definitely necessary to carry out research, but based on the current situation of Tianfeng Technology Company, Li Tianfeng said: "Grandpa, we will definitely carry out the development of the small signal turbofan engine, and it must be the fourth generation of the small signal turbofan engine, however, this research cannot be carried out for the time being." ”

Wang Guohong hurriedly asked, "Why?" ”

Li Tianfeng said: "We still have two large channel ratio turbofan engines under development, and we must wait for the successful development of these two engines before we can start the development of the fourth generation of small channel ratio turbofan engines." ”

Wang Guohong said: "How long will it take?" ”

Seeing that Wang Guohong asked so urgently, Li Tianfeng knew that it must be the comrades in the army who reported that they expressed a strong demand, otherwise, Wang Guohong, who was in a high position, would definitely not be in such a hurry.

Li Tianfeng thought for a while and said: "Grandpa, the fastest will be next year, and the possibility of starting research and development this year is relatively small." ”

It is completely acceptable to start research and development next year, Wang Guohong nodded and said: "It can also be next year, an advanced military small signal turbofan engine, we have been fighting for it for decades, and we have waited for decades, and we can wait for another year, and we can afford to wait." ”

It seems that Li Tianfeng replied that Wang Guohong was very happy, and Wang Guohong, who was old and comforted, couldn't help but glance at Li Tianfeng approvingly.

Then, Wang Guohong said: "Tianfeng, Ruobing is my most beloved baby granddaughter, you are now my grandson-in-law, if you have any problems at work in the future, you can directly find me, if nothing else, I will do it again, maybe I can help you, so that our military small letter is developed as soon as possible than the turbofan engine." ”

Hearing this, Li Tianfeng was pleasantly surprised, and immediately said happily: "Grandpa, with your help, then our engine development can be described as a green light all the way, unimpeded." ”

Wang Guohong also smiled: "Tianfeng, but don't look for me if you violate the policy." ”

……

Coming out of the study, Wang Ruobing immediately greeted him, "Tianfeng, grandpa didn't embarrass you!" ”

Li Tianfeng smiled happily: "No, grandpa is very kind today and talked to me about a lot of things on aero engines." ”

"Ahh Wang Ruobing was slightly stunned, in Wang Ruobing's impression, his grandfather was very majestic.

Li Tianfeng took Wang Ruobing's little hand and said, "Let's go." ”

Wang Ruobing nodded, and then said, "Tianfeng, are we going to play in the capital for a few more days." ”

Li Tianfeng nodded and said, "Yes, we should go for a walk, play and relax, and in addition, a few friends in the capital, I also plan to visit." ”

"Okay, then tomorrow we will go to the Forbidden City and the Summer Palace to play."

The two talked and laughed, holding hands, looking like a loving husband and wife, Wang Guohong just walked out of the study, saw the backs of the two, and couldn't help nodding happily, praising Li Tianfeng, the grandson-in-law, and even, Wang Guohong was thinking in his heart that if Li Tianfeng was in politics, the Wang family would definitely focus on training.

………

Li Tianfeng and Wang Ruobing had a good day of playing, and the next morning after the play, Li Tianfeng called Zhang Haiping.

Li Tianfeng said: "Director Zhang, are you busy, I'm in the capital." ”

Zhang Haiping said happily: "Mr. Li, you are in the capital, great, there is a new situation that is about to tell you, let's find a place and have a good talk." ”

"Oh." Li Tianfeng said: "Director Zhang, what's new, is it that your military wants to increase the order of turbofan 16." ”

Zhang Haiping said: "It has nothing to do with the military for the time being, Tianfeng, you have to be mentally prepared, this is not a good thing for you." ”

Li Tianfeng was slightly startled, and immediately said, "Director Zhang, without further ado, I'll come over immediately." ”

Wang Ruobing was beside Li Tianfeng, and when he heard the content of the call, he couldn't help but say worriedly: "Tianfeng, do you want me to go with you." ”

Li Tianfeng said: "Wife, you are at home, I will come when I go, don't worry, don't worry about me." ”

After speaking, Li Tianfeng was ready to go out.

Wang Ruobing said: "Tianfeng, wait a minute, I will ask Wang Liang to send you over, he is very familiar with the situation in the capital." ”

Li Tianfeng said: "It's okay." ”

…………
