Commissioning Engineering Center.

The turbofan 25 engine was pushed into the test workshop, and in front of the test bench, several test drivers were removing the colored silk and big red flowers on the engine, and an inspector next to them was also conducting a pre-test inspection.

"Squad leader, the turbofan 25 engine is so exquisite!"

"Yes, you see this fan case, fan blades, and this tail spray, it's very beautiful."

“……”

While disassembling the colored silk and saffron, everyone talked happily, and they were all happy, as if they had encountered a great event.

The test run of the first prototype of the turbofan 25 engine is a great joy for everyone.

Master Peng, the squad leader who led the test run, said loudly: "The first test run of the turbofan 25 engine is extraordinary. ”

"Squad leader! Rest assured, nothing will go wrong. ”

"Yes, squad leader, don't worry, we have carried out hundreds of tests of the turbofan 20 engine, and the test run of the turbofan 25 engine is much the same, there is no problem."

Seeing that everyone was full of confidence, the squad leader Master Peng clicked a little, and everyone worked together to install the engine on the test bench, check it correctly, and not long after, the first test alarm bell rang.

The first turbofan 25 engine enters the first test run!

in the office.

Li Tianfeng is thinking about the "Black Ghost" UAV is about to carry out a comprehensive design work, just now, Zhang Haiping called, the military will officially establish the "Black Ghost" UAV, after the Lunar New Year, the formal development task will also be issued.

The design of the "Black Ghost". Li Tianfeng naturally has a detailed plan, all the design of this drone is very clear in Li Tianfeng's mind, what Li Tianfeng has to do is how to move this drone out of his mind and turn it into a real design.

"Knock, knock!"

There was a knock at the door. Then, Sun Xiaoping walked in briskly with a happy face, and said happily: "Boss, the turbofan 25 engine has just completed the test run, and the first test run is very perfect, and all the performance parameters and test indicators are qualified." ”

Li Tianfeng did not go to the test run just now, Sun Xiaoping and Qiu Wenan came to the test site in person, and the test was completed. Sun Xiaoping came to report for the first time.

Hearing this, Li Tianfeng was also happy, the turbofan 25 engine, as he expected, performed very well, and the first test run passed smoothly.

Li Tianfeng said: "Okay, great, this is a very good start. I'm getting more and more confident in this engine. ”

Sun Xiaoping said: "Boss." According to the test plan, there will be a test run before the Lunar New Year, and after the Lunar New Year, a series of very comprehensive test runs will be carried out. ”

Li Tianfeng nodded. Li Tianfeng knew the test plan of the turbofan 25 engine, Li Tianfeng said: "The test run of the turbofan 25 engine, everything is going according to plan, in addition. The 'Black Ghost' drone military will soon set up a project, and the development task will be issued soon. ”

Sun Xiaoping said: "Boss, this is a great joy for us, I didn't think that the speed of the military is so fast." ”

The military is in dire need of an excellent drone, and the 'Black Ghost' is so good, the military is naturally very fast.

Li Tianfeng said: "Mr. Sun, the 'Black Ghost' will use two turbofan 21 engines as power, and your task is to develop a turbofan 21B engine on the basis of the turbofan 21 engine to meet the needs of the 'Black Ghost'." ”

At present, the turbofan 21 engine used in regional airliners is all the same model, that is, the turbofan 21A engine, and the turbofan 21B engine will be used as the power of the 'black ghost', and the requirements for the engine are definitely different, which needs to be modified.

The turbofan 21B engine will have more powerful continuous work ability, higher flight altitude and other characteristics.

In his office, Li Tianfeng exchanged views on the modified design of the turbofan 21B engine and Sun Xiaoping.

At present, the aero engine R&D and design center has completed the design of turbofan 25, which is just right to carry out the modification design of turbofan 21B engine.

……….

Waterfront spring villa area.

In the thirtieth year of the Chinese New Year's Eve, Li Tianfeng's family can be lively.

Li Jianxin and Xiao Ping, Li Tianfeng and Wang Ruobing's family of three, Sun Kang, Li Yuying and Sun Lin, everyone is eating a reunion dinner and watching the Spring Festival Gala.

Li Jianxin even opened a bottle of Wuliangye, while Sun Kang took the wine bottle and said with a smile: "Dad, I'll come, let me come, you can sit down." ”

As he spoke, Sun Kang took the wine bottle and poured three glasses of wine, one glass each for Li Jianxin, Li Tianfeng and Sun Kang himself.

As a parent, Li Jianxin spoke first, picked up his glass and said: "Tianfeng, Sun Kang, congratulations on your great achievements this year, and I hope you will make persistent efforts next year and achieve better results." ”

Li Tianfeng and Sun Kang, holding wine glasses, said in unison: "Dad, thank you, we will definitely create better results next year." ”

Sun Lin, a ghost elf, clapped his hands and said, "Okay, okay, grandpa, I will also get good results next year." ”

Li Jianxin smiled and said lovingly: "Our Sun Lin, we will come back next year with a first place." ”

Everyone laughed happily, and the family was happy.

…………

Early in the morning of the second day of the Lunar New Year, Li Tianfeng held his suitcase, Wang Ruobing held his son, and the family of three was ready to get into the car.

Li Jianxin and Xiao Ping stood at the door of the villa, and Xiao Ping even advised: "Tianfeng, drive slowly, get to the capital, and call home." ”

The first cub of the first year, the second lang of the first year.

Li Tianfeng, the son-in-law, went to the capital to pay New Year's greetings to his parents-in-law and the elders of the Wang family.

Li Jianxin gently pulled Xiao Ping and said, "Wife, the car is far away, we entered the house, and it was cold outside." ”

The Bentley off-road vehicle is parked in the paid parking lot of Huangping Airport, and this car will be parked here for a few days, and when it comes back from the capital, it will continue to drive this car back.

Li Tianfeng held his son in one hand and pulled the suitcase with the other, while Wang Ruobing followed behind Li Tianfeng, and everyone walked out of the parking lot together.

In the waiting hall, seeing the ARJ21 passenger plane, Wang Ruobing said: "Tianfeng, the plane seems to be coming, it should be that plane." ”

Li Tianfeng looked at the model and nodded, the engines of this aircraft are two turbofan 21 engines, and the engines look very beautiful.

At present, there are two types of engines for the ARJ21 regional airliner, all of which are produced by Tianfeng Technology Company, of which the turbofan 21 engine is also installed.

Li Tianfeng said: "It's this plane, wife, look at the engine, it's produced and manufactured by our Tianfeng Technology Company." ”

Wang Ruobing smiled, "Tianfeng, look at the planes parked at this airport, most of the planes are powered by Tianfeng Technology Company. ”

Looking at it this way, it goes without saying that the ARJ21 passenger aircraft is Airbus A320, Boeing 737 and other models, and most of its engines are products of Tianfeng Technology Company.

Li Tianfeng took a look and found that this was the case, Li Tianfeng was very familiar with his own engine, and he could see it at a glance.

Li Tianfeng said: "In the domestic market, the engines we produce and manufacture have occupied most of the share, but the international market share is small, and our future goal is to gradually increase the share of trunk airliner engines in the international market." ”

Wang Ruobing said: "Tianfeng, you are amazing! ”

After the two chatted for a while, they began to board the plane and sit in a comfortable position, Li Tianfeng looked back at the situation in the plane, and thought in his heart, the domestic aviation market is really booming during the Spring Festival, and the entire plane is full and full.

The royal family of the capital.

Li Tianfeng's son-in-law has a very high status and is very popular in the Wang family, the elders of the Wang family are very enthusiastic about Li Tianfeng, and the three generations of the Wang family are of the same age as Li Tianfeng, and they quickly get along.

Wang Liang is the most familiar with Li Tianfeng, and seeing that there are no elders present, he can't help but smile and say, "Brother-in-law, there is nothing to do in the afternoon anyway, I'll take you out for a walk." ”

"Brother-in-law, I'll go too."

"I'll go too!"

Everyone enthusiastically signed up, Wang Ruobing smiled, Wang Ruobing knew everyone's little abacus.

Wang Liang smiled and said, "Forget it, my car can't seat so many people." ”

"Don't be afraid, we have our own car."

"Yes, Ryoko, you want to eat alone, I won't do it."

Seeing this, Li Tianfeng laughed, enjoying this atmosphere very much, Li Tianfeng said generously: "It's okay, everyone goes, this time I have a treat, everyone can choose what they want to buy." ”

"Oh yes, it's better to be a brother-in-law!"

Everyone cheered, and then went out together, and Wang Liang even pulled Wang Ruobing into the car, "Sister, let's go together, anyway, the little nephew has a nanny with him." ”

Wang Ruobing smiled for a while, and got into Wang Liang's BMW car with Li Tianfeng, this car was bought by Li Tianfeng for Wang Liang at the beginning, Wang Liang has a sweet mouth, is diligent, and Li Tianfeng likes it.

Everyone and their group arrived at Wangfujing and began to sweep the goods, Li Tianfeng and Wang Ruobing looked at each other and smiled, the two of them were very happy, even if everyone bought luxury goods, Li Tianfeng's net worth was there, and this money was nothing at all.

However, everyone is a child of a great family, and they are more measured, not excessive, generally there are slightly more popular products and less luxury goods.

Wang Ruobing also picked out a few clothes and a pair of leather shoes for Li Tianfeng. Li Tianfeng also chose some things for Wang Ruobing.

After shopping for a few hours, everyone quickly returned with a large bag and a full load.
