It was Mr. Lin who knocked in. Seeing Li Tianfeng, Mr. Lin was slightly stunned at first, and then said enthusiastically: "Mr. Li, you are a rare guest, I didn't expect you to be in our group company."

Mr. Wu said: "Mr. Lin, I invited Mr. Li to come here. Let's exchange some things in the field of aviation engine technology."

Li Tianfeng also said: "Mr. Wu has a profound technical attainment, so I came here to learn from Mr. Wu."

After a polite greeting, Mr. Lin asked Li Tianfeng unknowingly, and Mr. Lin said: "Mr. Li, how is the development of your turbofan 20 engine progressing? If it weren't for Mr. Wu, our turbofan 19 engine, there might not be any technical outline yet."

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

Mr. Lin said: "Mr. Li, I heard that the design of the turbofan 20 is for you to take charge of it yourself. Is it convenient to reveal something about the turbofan 20 engine to us?"

Li Tianfeng smiled, "Mr. Lin, the military proposed a series of technical conditions at the beginning. We designed the design completely according to the requirements of the military, but only some performance is slightly higher than the requirements of the military."

"Ah!" 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.

Mr. Wu also said: "Mr. Li, the Yangtze River is really the waves that push the waves behind us, we are old."

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

Mr. Wu said: "Mr. Li. According to your technical strength, your turbofan 20 engine will definitely be successfully developed. I will do a lot of things. I, the old guy, will lose to you."

Li Tianfeng hurriedly said, "Mr. Wu, you are highly respected. Never say such words, we cannot afford to take on them."

In Mr. Wu's office, Mr. Lin and the three of them chatted for a long time. When they left AVIC Group, Mr. Lin personally sent Li Tianfeng to the gate.

Seeing Li Tianfeng get in the car and go away, Mr. Lin thought to himself that the result of this battle between the turbofan 19 and the turbofan 20 engine was really unpredictable.

Originally, Mr. Lin thought that AVIC Group had a great business, rich resources and strong strength, and would definitely win in the end. Now it seems that this is not necessarily the case. Without the end, everything is hard to say.

Tianfeng Technology Company.

After returning from Beijing, Li Tianfeng devoted himself to the intensive work. Not only did he go to Qingshi base personally, inspect the construction situation, but he also personally inquired about the procurement of machine tool equipment.

Tianfeng Technology Company is currently busy with production. It has to deliver 50 turbofan engines to Embraer every month, as well as to COMAC, and many military engines. The monthly aircraft engine production and manufacturing has exceeded 100.

More than 100 aircraft engines are produced and manufactured every month, most of which are larger than turbofan engines. The production task is very heavy.

It is also a very urgent matter to do a good job in building the Qingshi base and purchasing equipment, and Li Tianfeng naturally takes it to heart.

The construction of Qingshi Base was very smooth. Because the construction of the factory building was much shorter than the construction period. If it weren't for the factory building of Tianfeng Technology Company, each factory building would have an area of ​​tens of thousands of square meters, with extremely high standards and requirements, and many factories might have been completed.

The first phase of the project, ten modern high-standard factory buildings with a total of more than 10,000 square meters, plus a modern office building, and a large logistics warehouse.

For the construction of ten factories, more than half of the factories have been topped out, and the installation of water, electricity and ventilation facilities in the factory is underway. The remaining factories have also completed the main construction. Judging from the progress, the ceiling should be fully completed within one month.

The office building is not large in scale, but it is very modern and has a very unique shape. This is specially designed by someone. Each floor is more than 2,000 square meters and is six floors high, which is enough for the entire Qingshi Base office.

The total value of equipment procurement at Qingshi Base reaches tens of billions of yuan, including many high-end imported machine tool equipment. The procurement of many imported equipment has entered the procurement process. In another two or three months, some imported equipment will arrive at Qingshi Base and then the equipment installation and debugging begins.

In the office.

Li Tianfeng felt relieved. After many days of hard work, the 3D color picture of the turbofan 20 engine was finally completed.

The engine looks very exquisite, beautiful, and has a modern and industrial atmosphere. Although it is just a 3D color picture drawn by a computer, if you don’t look closely, you really think it is a real color photo of the engine.

The engine is long cylindrical, and its size is basically the same as the Russian Al-31 engine, but its appearance and structure are very different, especially the details, which seem to be more classy and higher-end than the Russian Al-31 engine.

The engine has a diameter of about 1 meter and a length of 4 meters. Such a small cylindrical object is to be stuffed into a 3-level fan, a 6-level compressor, and a 3-level turbine. It can converge and expand the nozzle, a combustion chamber, afterburner, as well as a cooling air passage, and a fuel control system is installed around it.

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

Beautiful and comfortable looking at the 3D color picture of the freshly baked turbofan 20 engine, then said, it was 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. Wu Tiejun, a freshman, is even considering joining the army. In his dormitory, Wu Tiejun has the same idea as him.

"Boss, you are really ready to join the army and serve the motherland."

"San Lao, do you have this idea too?"

"Well, I'm just thinking."

Wu Tiejun was talking to the third brother in his dormitory about joining the army. Lao Mo ran in happily, "Boss, third brother, get up quickly, go to the gymnasium, it's very lively."

Wu Tiejun said: "Why, is that?"

Lao Mo hurriedly said: "Yes, yes, boss, it was the army that was conducting recruitment propaganda. There were many people coming up from the army, and the curtain had been pulled up. The promotional film "Entering the Military Camp" was about to begin."

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

There were already many people in the stadium, which was very lively. The white curtain had been pulled up. Several people in military uniforms were standing on the temporary platform. One of the captains was holding a trumpet in his hand and was promoting it to everyone.

"Students, this is our recently recorded promotional video and walked into the military camp to show everyone the style of our modern soldiers and some of our latest weapons and equipment."

The captain waved his hand and four big words "Walk into the military camp" appeared on the white big screen, accompanied by passionate melody and music.

Seeing this, Wu Tiejun hurriedly called his third brother and youngest brother to stand. At this moment, the entire noisy stadium became quiet. Everyone looked at the screen and the sound of promotional videos sounded in their ears.

On the screen, a mighty army appeared. On the ground, tanks and armored vehicles were galloping, and in the air, a formation of 10 martial arts was flying. Everything was very visually impactful, making people feel excited all of a sudden.

"This is our new type of Martial Arts Ten, so majestic!"

"Not only is the Martial Helicopter, but also our new transport helicopter, Zhi Twelve!"

“…”

When everyone saw the helicopter on the screen, many people exclaimed, especially those military enthusiasts, such as Wu Tiejun, who were so excited that their bodies trembled slightly.

"It would be great if I could become an army aviation force. It would be worth the rest of my life when flying into the blue sky in a new Martial Arts Ten."

What excited Wu Tiejun even more was that there was a close-up of Wu Zhishi. From far to near, the camera pulled a Wu Zhishi in the air to everyone's eyes. This Wu Zhishi magnified in front of everyone's eyes, revealing the majesty of Wu Zhishi, showing its powerful firepower.

"Wow, so majestic!"

Many people exclaimed in surprise. They saw the Wu Zhishi, the strong lines of Wu Zhishi, and the hanging missiles.

As the picture turned, the background of the picture was obviously the Gobi desert in the northwest. A Wuzhishi was firing violently, the missiles roared, and the targets on the ground were like destruction!

“It’s so spectacular!”

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

The picture turned again, a fleet of transport aircraft was flying, and three new YEV aircraft were flying in the finished font, starting to land towards the airport in the distance.

Three Yun-Eight aircraft landed at the airport one by one, and the plane stopped, and the huge cabin door at the rear of the plane opened. Among the two, a team of majestic and fully armed soldiers walked out. Another aircraft slowly drove out an infantry combat vehicle from the inside.

"Wow, infantry fighting chariot!"

"This is our latest infantry fighting vehicle!"

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

“…”

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

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

Such military recruitment propaganda has been staged in many universities. Many students saw the mighty Wuzhishi and our new Yunba aircraft, and they all joined the army. Many people's dream is to fly the majestic Wuzhishi, protect their families and the country, and defend our territory.
