Chengnan Base, No. 2 Assembly Workshop.

Several technicians were happily looking at a J-18 fighter jet that was about to be installed and taken off the line. This was an export-type J-18 fighter jet.

One of the technicians said: "This is the 30th J-18 fighter jet exported, with a total of 30 aircraft. The production and manufacturing are progressing so quickly!"

"Yes, starting from the 31st aircraft, we will be ready to deliver the second user."

J-18 fighter jets have entered small batch production and manufactured nearly ten fighters every month, half of which are export-type J-18 fighters, used for export to foreign users.

The number of J-18 fighter jets delivered by the military has basically reached 30. It is estimated that it will not take long. As the production and manufacturing process becomes more mature and the production organization becomes smoother, the J-18 fighter jets will enter mass production and manufacturing.

As for the J-30 fighter jets, after about half a year of small-scale production and manufacturing, they have entered mass production and manufacturing since the beginning of this month, and the production and manufacturing speed has been significantly accelerated.

The J-30 fighter jets are manufactured in small batches, with about five being produced per month, and they are produced in large batches, and the monthly output is at least doubled.

Since entering mass production and manufacturing at the beginning of this month, a J-30 fighter jet has been offline almost every two or three days. If the second phase of the Chengnan Base is put into use, the monthly output of the J-30 fighter jet will increase.

A technician said: "As the J-30 fighter jet enters mass production, our No. 2 assembly workshop is the busiest."

Another technician next to him said: "If the J-18 fighter jets also enter mass production, our No. 2 assembly workshop will be even more enthusiastic."

While everyone was talking and chatting, the J-18 fighter jet was taken off the line and slowly left the No. 2 assembly workshop under the traction vehicle.

On the J-30 fighter production line next to it, the assembly of a J-30 fighter is coming to an end. It is estimated that it will be offline a little later today.

Whether it is the J-30 fighter or the J-18 fighter, it is gradually fully on track and is delivered steadily. The turbofan 30 engine has been tested and verified by a large number of parts and process, and has also begun to be assembled into the first prototype.

Tianxin City, Hexi Base.

In the huge assembly workshop, a turbofan 30 engine has taken shape. The engine is very spectacular on the assembly bench.

The huge fan is more than 3.6 meters tall, and the height of the assembly bench looks almost as high as one floor. An adult stood in front of the fan and could only touch the fan blades even if he reached out.

The biggest one is the fan. As for high-pressure compressors, combustion chambers, etc., the turbine is slightly larger, but the diameter of about one meter is still much more delicate than a 3.6-meter fan.

"It is worthy of being the turbofan 30. It is one of the largest turbofan engines in the world. Take a look. How beautiful and spectacular!"

"Such awesome engine is actually manufactured here. It's so sturdy!"

"Look at Lao Li, Lao Zhao and the others, how honorable it is to participate in the assembly of the first turbofan 30 engine."

“…”

The engine assembly is coming to an end. In the assembly workshop, many workers looked happy and praised the problem with their eyes. From everyone's words, it is not difficult to feel the strong sense of pride and sense of accomplishment.

Today, Yang Xianfeng was wearing a white shirt, tied his hair, and his hair was even more meticulous. He looked very energetic. If he didn't know the inside story, he would definitely think that Yang Xianfeng had something big to say when he saw Yang Xianfeng's appearance.

The successful assembly of the turbofan 30 engine was Yang Xianfeng's happy event.

Since the turbofan 30 engine entered the assembly, Yang Xianfeng has been paying attention to the assembly progress every day. Even Yang Xianfeng, who was the chief engineer, often played a guest role in the assembly workshop in the assembly workshop when he was intrigued.

Yang Xianfeng guided everyone to carry out the engine assembly. During the assembly process, Yang Xianfeng also analyzed and solved these technical problems with everyone.

He is very familiar with the assembly process of the turbofan 30 engine. Yang Xianfeng knows that the first turbofan 30 engine will be completed this morning. Yang Xianfeng specially wore a white shirt and tied it. Of course, the jacket is still the work clothes of Tianfeng Technology Company.

At about 10:30 in the morning, the assembly of the first turbofan 30 engine had just been completed. Several technicians and inspectors were conducting a complete inspection of the engine. Outside the gate of the assembly workshop, Yang Xianfeng accompanied Li Tianfeng in.

Today, Li Tianfeng came here in person, and together with Li Tianfeng, Sun Xiaoping, chief designer of the turbofan 30 engine, chief craftsman Zeng Qinghai and others.

Walking into the huge assembly workshop, looking around, there are all engines being assembled, such as the turbofan 16, turbofan 17, turbofan 18, and turbofan 21 engines.

The turbofan 21 engine has the most. This regional passenger aircraft engine accounts for most of the share of international regional passenger aircraft and small business aircraft due to its excellent comprehensive performance, ultra-low fuel consumption and ultra-low noise.

Basically, Li Tianfeng comes to the Hexi base in Tianxin City several times every month, and he has a good understanding of the entire Hexi base.

However, as the general manager of the Hexi base, Yang Xianfeng was still accompanying Li Tianfeng, introducing to Li Tianfeng while walking.

Yang Xianfeng said: "Boss, our engines are very popular, especially the turbofan 21 engine, which will be produced and manufactured immediately to reach 2,000 units."

The turbofan 21 engine has a large demand every year, and the annual production and manufacturing quantity has reached hundreds. From the successful development to the present, it will soon reach 2,000 production and manufacturing quantity in just a few years.

Li Tianfeng walked to a turbofan 21 engine, which is a turbofan 21 engine that is about to be assembled. The fuselage has a conspicuous number "s21001998".

This is the official mass-produced engine No. 1998. Not far away, the No. 2000 engine is being assembled. It is estimated that in a few days, this engine will be assembled and will be delivered to the user after passing the factory trial run.

Li Tianfeng said with satisfaction: "Mr. Yang, Mr. Sun, and the turbofan 21 engine are our most successful civil passenger aircraft engine."

The turbofan 21 engine has a thrust level of 12,000 pounds, and has an advanced digital fuel regulator with adjustable thrust. It can be widely used in various medium and small aircraft, regional passenger aircraft, business aircraft, etc., so the market is very broad.

With such a large demand and almost monopolizing the entire international regional passenger aircraft engine market, the turbofan 21 engine is naturally a very outstanding engine.

And through predictions and estimates, the prospects for the turbofan 21 engine will remain broad in the next two or three decades. It is estimated that the total production and manufacturing of this engine will reach 20,000 or 30,000 units, and it is possible that there will be more.

If a civilian regional passenger aircraft engine can be produced to reach 20,000 or 30,000 units, this will be a very good result, and it also means that this engine has been designed very successfully.

Sun Xiaoping smiled and said, "Boss, as long as we are willing, we can also launch a civilian passenger aircraft engine with the same technical level as the turbofan 21 engine, with thrust of 20,000 pounds and 50,000 pounds respectively."

The turbofan 16 engine has a thrust of 50,000 pounds and the turbofan 17 engine has a thrust of 20,000 pounds, but these two engines are early products of Tianfeng Technology and use the first generation core engine technology of Tianfeng Technology.

Sun Xiaoping’s implication is that it is possible to launch more advanced engines with a thrust level of 20,000 pounds and 50,000 pounds based on the second-generation core engine.

The maximum thrust is 20,000 pounds, which can be used for power from 100 to 150 passenger aircraft, and the maximum thrust is 50,000 pounds, which can be used for power from 150 to 200 passenger aircraft.

For example, the turbofan 16 engine has a maximum thrust of 10,000 pounds. It is currently mainly used in Airbus A320, Boeing 737 and other models, and the cumulative flight time has reached millions of hours. So far, there have been almost no major failures.

Li Tianfeng smiled and said, "At present, our turbofan 16 and turbofan 17 have both responded well in the market and their sales performance is also good. There is no need to develop more advanced engines for the time being."

Li Tianfeng estimated that if he launched an engine with a thrust level of 20,000 pounds and 50,000 pounds based on the second-generation core aircraft, it would definitely be as outstanding as the turbofan 21 engine, and it would definitely greatly extinguish the trunk passenger aircraft engine market that the traditional three strongest in the world have always occupied.

The mainline passenger aircraft engine market is mainly controlled by the three traditional companies, namely Rolls, Rolls, Puhui and Ge. Tianfeng Technology Company only occupies part of the 150 to 200-seat passenger aircraft engine market with the turbofan 16 engine.

At present, there is no need to launch a very advanced trunk passenger aircraft engine, which will cause a strong rebound from the traditional three strongest people, and will not benefit Tianfeng Technology.

Wait for a while, this is Li Tianfeng's idea, so he has never been in a hurry to launch more advanced engines. Instead, he has maintained the production of turbofan 16, turbofan 17 and turbofan 18 engines. These three engines can also be sold hundreds of units every year, and the results are pretty good.

Seeing that Li Tianfeng had no plans to develop more advanced trunk passenger aircraft engines, Sun Xiaoping had to give up. In fact, in Sun Xiaoping's mind, he had long wanted to develop these engines, especially with the completion of the first prototype of the turbofan 30 engine, this idea became even stronger.

Li Tianfeng seemed to know what Sun Xiaoping was thinking, but Li Tianfeng did not continue on this topic, but smiled slightly and said, "Let's go and take a look at the turbofan 30 engine."

As you have seen, on the assembly bench in the distance, the turbofan 30 engine is very conspicuous, completely outspoken!
