It was Mr. Lin who knocked on the door and came in, and when he saw Li Tianfeng, Mr. Lin was slightly stunned at first, and then said enthusiastically: "Mr. Li, a rare guest, I didn't expect you to be in our group company." ”

Wu Lao said: "Mr. Lin, I invited Mr. Li to come over, and we will exchange some things in the field of aero engine technology." ”

Li Tianfeng also said: "Wu Lao's technical attainments are profound, I came here to learn from Wu Lao." ”

After greeting politely, Mr. Lin unconsciously asked about Li Tianfeng, and Mr. Lin said: "Mr. Li, how is the development progress of your turbofan 20 engine, our turbofan 19 engine, if it weren't for Wu Lao, there may not be a design technical outline until now." ”

Li Tianfeng said: "Mr. Lin, our turbofan 20 engine is similar, it has just completed the design technical outline and has just entered the comprehensive design stage. ”

Mr. Lin said: "Mr. Li, I heard that the design of the turbofan 20 is in charge of you personally, is it convenient to reveal a little bit about the turbofan 20 engine to us." ”

Li Tianfeng smiled, "Mr. Lin, at the beginning, the military proposed a series of technical conditions, and we completely designed it in accordance with the requirements of the military, but some of the performance was slightly higher than the military's requirements." ”

"Ahh Mr. Lin was slightly surprised, and did not think that some of the performance of the turbofan 20 engine was slightly higher than the military's requirements.

Wu Lao also said: "Mr. Li, it's really the waves of the Yangtze River pushing the back waves, we are old." ”

Li Tianfeng is generally quite satisfied with his turbofan 20 engine, Li Tianfeng smiled and said modestly: "Wu Lao, whether our turbofan 20 engine can be successfully developed is still unknown." ”

Wu Lao said: "Mr. Li, according to your technical strength, your turbofan 20 engine will definitely be successfully developed." Do a lot, and I'm going to lose at your hands. ”

Li Tianfeng hurriedly said: "Elder Wu, you are highly respected, don't say such things, we can't afford it." ”

In Wu Lao's office, plus Mr. Lin. The three chatted for a long time, and when they left AVIC Group, Mr. Lin personally sent Li Tianfeng to the gate.

Watching Li Tianfeng get into the car and go away, Mr. Lin thought in his heart, the result of this turbofan 19 and turbofan 20 engine dispute is really unpredictable.

Originally, Mr. Lin thought that AVIC Group had a big business and rich resources. Strong strength, will definitely win in the end, now it seems, not necessarily like this, until the end, everything is difficult to say.

Tianfeng Technology Company.

After returning from the capital, Li Tianfeng threw himself into intense work again, and not only went to the Qingshi base in person. He inspected the construction situation and personally inquired about the procurement of machine tools and equipment.

The current Tianfeng Technology Company. It is a busy production scene, with 50 turbofan engines to be delivered to Embraer every month, as well as many engines from COMAC and the military, and more than 100 aero engines are manufactured every month.

More than 100 aero engines are produced every month, most of which are turbofan engines. The production tasks are very heavy.

It is also very urgent to do a good job in the construction of the Qingshi base and the procurement of equipment, and Li Tianfeng naturally cares about it.

The construction of the Qingshi base is very smooth, because the construction of the factory is much shorter than the construction of the building. If it were not for the factory buildings of Tianfeng Technology Company, each plant area is tens of thousands of square meters, and the standards and requirements are extremely high, and many factories may have been completed.

In the first phase of the project, there are 10 modern high-standard factories of more than 10,000 square meters, plus a modern office building and a large logistics warehouse.

The construction of ten plants, more than half of the plant has been capped, the installation of water and electricity facilities in the factory, ventilation facilities, etc., and the rest of the remaining plants have also completed the main construction.

The office building is not large, but it is very modern, and the shape is also very chic, which is specially designed by a special person, with more than 2,000 square meters on each floor and six floors high, which is enough for the office of the entire Qingshi base.

The total value of equipment procurement in Qingshi base has reached billions of yuan, including many high-end imported machine tools and equipment, and the procurement of many imported equipment has entered the procurement process.

In the office.

Li Tianfeng's heart was relieved, and after many days of hard work, the 3D color map of the turbofan 20 engine was finally completed.

The engine looks very exquisite, very beautiful, very modern industrial atmosphere, although it is only a 3D color map drawn by the computer, but do not look closely, I really think it is a physical color photo of the engine.

The engine is long cylindrical, and the size and size are basically the same as the Russian-made AL-31F engine, but the shape and structure are very different, especially in the details, which are more high-grade and high-end than the Russian-made AL-31F engine.

The engine is about 1 meter in diameter and 4 meters in length, and such a small cylindrical object is stuffed with a 3-stage fan, a 6-stage compressor, a 3-stage turbine, a convergent and expandable nozzle, a combustion chamber, an afterburner combustion chamber, a cooling air channel, and a fuel control system around it.

Li Tianfeng looked at the 3D color map of the turbofan 20 engine, and thought to himself, this is really "a dojo in a snail shell", which shows the technical difficulty, and it is really difficult for ordinary people to imagine the technical content and difficulty.

Meimei, in a comfortable mood, looked at the 3D color map of the freshly baked turbofan 20 engine, and then said, it is time to take a look at the design work of the turbofan 20 engine. Then, Li Tianfeng walked towards the aero engine R&D center......

………

Wu Tiejun is a military enthusiast, and Wu Tiejun, who is a freshman, is even thinking about joining the army, and in his dormitory, Wu Tiejun is not the only one who has the same idea as himself.

"Boss, you are really ready to put pen to paper and serve the motherland."

"Third child, do you have such an idea?"

"Well, that's exactly what I thought."

Wu Tiejun was talking to the third child in his dormitory about joining the army, and the old man ran in happily, "Boss, third child, hurry, get up, go to the gymnasium, it's lively." ”

Wu Tiejun said: "Old, is it true? ”

Lao Mo hurriedly said: "Yes, yes, boss, it is the army that is carrying out recruitment propaganda, there are many people in the army, the curtain has been raised, and the propaganda film "Into the Barracks" is about to start. ”

"Really." Wu Tiejun immediately put on his clothes and waved his hand: "Let's go, let's go to the stadium." ”

In the stadium, there were already a lot of people, very lively, the white curtain had been raised, several people in military uniforms were standing on the makeshift platform, and one of the captains was still holding a bullhorn in his hand, and was promoting to everyone.

"Students, this is a propaganda video we recently recorded -- walking into the barracks to show you the demeanor of our modern soldiers, as well as some of our latest weapons and equipment."

The captain waved his hand, and on the big white screen, four big words "enter the barracks" appeared, accompanied by passionate melodies and music.

Seeing this, Wu Tiejun hurriedly beckoned his third child and Lao Mo to stand up, and at this time, the entire noisy stadium quieted down, everyone looked at the screen, and the sound of the promotional video sounded in their ears.

On the screen, what appeared was a mighty division, on the ground, tanks and armored vehicles galloping, in the air, the formation of Wuzhi ten was flying, everything was very visually impactful, making people's blood boil all of a sudden.

"This is our new Wuzhi Shi, so majestic!"

"There is not only Wuzhi 10, but also our new transport helicopter Zhixi!"

“……”

When everyone saw the helicopter on the screen, many people exclaimed, especially those military enthusiasts, such as Wu Tiejun, who trembled slightly with excitement.

"If I can become an army aviation soldier, it will be great, driving the new Wuzhi 10 to fly into the blue sky, this life is worth it."

What makes Wu Tiejun even more excited is that there is also a close-up of Wu Zhi Shi, from far to near, the camera pulls a Wu Zhi Shi in the air to everyone's eyes, this Wu Zhi Shi is enlarged in front of everyone's eyes, revealing Wu Zhi Shi's grandeur, showing its powerful firepower.

"Wow, that's mighty!"

Many people exclaimed in amazement, seeing this Wuzhishi, seeing the resolute lines of Wuzhishi, and also seeing the missiles hanging one after another.

As soon as the picture turned, the background of the picture was obviously the Gobi Desert in the northwest, a Wuzhi Ten was firing fiercely, the missiles were whistling, and the target on the ground was simply like pulling rot and decaying!

"It's spectacular!"

Seeing this scene, many people exclaimed again and sighed, such a picture, Wu Zhishi's powerful combat power was fully revealed!

The picture turned again, a transport plane formation was flying, and three new Y-8 planes were flying in a zigzag shape, and began to land towards the airport in the distance.

The three Y-8 planes landed at the airport one by one, the planes came to a standstill, the huge hatch at the tail of the planes opened, and among the two planes, a group of majestic and heavily armed soldiers walked out. Another plane, slowly moving out of it was an infantry fighting vehicle.

"Wow, infantry fighting vehicles!"

"This is our newest infantry fighting vehicle!"

"God, when will Yunba be able to airlift infantry fighting vehicles!"

“……”

Seeing this scene, thousands of students in the entire stadium erupted in thunderous cheers, and then, bursts of applause rang out.

Wu Tiejun's face was slightly red with excitement, he clenched his fists tightly, and thought firmly in his heart, I want to participate, I must join the army!

This kind of military recruitment propaganda has been staged in many universities, and many students have seen the mighty Wuzhishi and our new Yun-8 aircraft, and they have put pen to paper, and many people's dream is that the army aviation will fly the majestic Wuzhishi to protect the country and defend our territory.
