Chengnan base, No. 2 assembly workshop.

Several technicians were beaming and happily looked at a J-18 fighter that was preparing to be assembled and rolled off the assembly line, which was an export-oriented J-18 fighter.

One of the technicians said: "This is the 30th J-18 fighter to be exported, a full 30, and the production and manufacturing progress is really fast!" ”

"Yes, from the 31st, it will be ready to deliver the second user."

The J-18 fighter entered small batch production, with nearly ten aircraft produced every month, half of which are export-oriented J-18 fighters for export to foreign users.

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

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

The J-30 fighter is manufactured in small batches, and the number of aircraft produced and manufactured per month is about five, and the monthly output has at least doubled when it enters mass production.

Since entering mass production at the beginning of this month, almost every two or three days, a J-30 fighter has rolled off the assembly line, and if the second phase of the Chengnan base project is put into use, the monthly output of J-30 fighters will increase.

A technician said: "With the J-30 fighter entering mass production, our No. 2 assembly workshop is the busiest. ”

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

When everyone was talking and chatting, the J-18 fighter went off the assembly line, and under the traction of the tractor, it slowly came out of the No. 2 assembly workshop.

On the production line of the J-30 fighter next to it, the final assembly of a J-30 fighter is nearing completion. 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 the right track and delivered steadily, and the turbofan 30 engine, after a large number of parts trial production and process verification, has also begun to enter the final assembly of the first prototype.

Tianxin City. Hexi base.

In the huge assembly workshop, a turbofan 30 engine has begun to take shape, and on the final assembly bench, the engine is very spectacular.

The huge fan, directly more than 3.6 meters, coupled with the height of the assembly bench, looks almost as high as a floor, an adult standing in front of the fan, can only touch the fan blades.

The biggest is the fan. As for the high-pressure compressor, the combustion chamber is not large, and the turbine is slightly larger, but the diameter of about one meter is still much more delicate than that of a 3.6-meter fan.

"It's the turbofan 30, one of the world's largest turbofan engines, take a look. How beautiful, how spectacular! ”

"Such a engine. It's actually made in our place, it's too hanging! ”

"Look at Lao Li, Lao Zhao, what an honor to participate in the final assembly of the first turbofan 30 engine."

“……”

The final assembly of the engine is coming to an end, and the final assembly workshop is in. Many workers were happy, and from everyone's words, it was not difficult to feel a strong sense of pride and achievement.

Today's Yang Xianfeng. specially wore a white shirt, tied a tie, and combed his hair meticulously, the whole person looked very energetic, I don't know the inside story, seeing Yang Xianfeng's appearance, I must have thought that Yang Xianfeng had some great joy.

The successful assembly of the turbofan 30 engine is a great joy for Yang Xianfeng.

Since this turbofan 30 engine entered the final assembly, Yang Xianfeng paid attention to the assembly progress every day, and even, Yang Xianfeng, who was born as a chief engineer, also played the role of a technician in the assembly workshop from time to time when he was interested.

Yang Xianfeng instructed everyone to carry out the final assembly of the engine, and encountered technical problems in the final assembly process, Yang Xianfeng also worked with everyone to analyze and solve these technical problems.

Yang Xianfeng knows very well about the turbofan 30 engine assembly process, Yang Xianfeng knows that the first turbofan 30 engine assembly will be completed this morning, Yang Xianfeng specially wore a white shirt and tie, of course, the jacket is still the work clothes of Tianfeng Technology Company.

At about half past 10 o'clock in the morning, the final assembly of the first turbofan 30 engine had just been completed, and several technicians and inspectors were inspecting the completion of the engine.

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

Walking into the huge assembly workshop, you can see all the engines being assembled, such as turbofan 16, turbofan 17, turbofan 18 engine, and turbofan 21 engine.

The turbofan 21 engine has the most, and this regional airliner engine, because of its excellent comprehensive performance, ultra-low fuel consumption and ultra-low noise, occupies the vast majority of the share of aircraft engines such as international regional airliners and small business jets.

Basically, Li Tianfeng has to come to the Hexi base in Tianxin City several times a month, and he knows the entire Hexi base well.

However, as the general manager of the Hexi base, Yang Xianfeng still accompanied Li Tianfeng, and introduced Li Tianfeng as he walked.

Yang Xianfeng said: "Boss, our various engines are very prosperous, especially the turbofan 21 engine, which will be produced and manufactured up to 2,000 units soon." ”

Turbofan 21 engine, the annual demand is very large, the annual production and manufacturing number is hundreds of units, from the successful development to the present, in just a few years, will soon reach 2000 units of production and manufacturing.

Li Tianfeng walked next to a turbofan 21 engine, which was about to be assembled, and the fuselage had the eye-catching number "WS21001998".

This is the official production of the 1998 engine, not far away, there is the 2000 engine in the assembly, it is estimated that in a few days, this engine will be completed, through the factory test, will be delivered to the user.

Li Tianfeng said with satisfaction: "Mr. Yang, Mr. Sun, the turbofan 21 engine is our most successful civil airliner engine. ”

The turbofan 21 engine, with a thrust rating of 12,000 pounds, and has an advanced digital fuel regulator, adjustable thrust, can be widely used in a variety of small and medium-sized aircraft, regional airliners, business jets, etc., so the market is very broad.

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

And through prediction and estimation, in the next two or three decades, the prospect of the turbofan 21 engine is still broad, and it is estimated that the total number of this engine will reach 20,000 or 30,000 units, or even more.

If a civilian regional airliner engine can really be produced to reach 20,000 or 30,000 units, it will be a very good achievement, and it also means that this engine is very successfully designed.

Sun Xiaoping smiled and said: "Boss, as long as we want, we can also launch a civil airliner engine of the same technical level as the turbofan 21 engine, with a 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 belong to the early products of Tianfeng Technology Company and use the first-generation core engine technology of Tianfeng Technology Company.

Sun Xiaoping's implication is that on the basis of the second-generation core engine, more advanced engines with 20,000 pounds and 50,000 pounds of thrust can be launched.

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

For example, the turbofan 16 engine, with a maximum thrust of 10,000 pounds, is currently mainly used for 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 said with a smile: "At present, our turbofan 16 and turbofan 17 market response is good, and the sales performance is also good, and there is no need to develop more advanced engines for the time being." ”

Li Tianfeng estimates that if he launches a 20,000-pound and 50,000-pound thrust engine on the basis of the second-generation core engine, it will definitely be as good as the turbofan 21 engine, which will definitely greatly squeeze out the mainline passenger aircraft engine market that the world's traditional three have always occupied.

The trunk airliner engine market is mainly dominated by the traditional three companies, namely Rolls-Royce, Pratt & Whitney, and GE, while Tianfeng Technology Co., Ltd. only occupies part of the 150-200-seat passenger aircraft engine market with its turbofan 16 engine.

At present, there is no need to launch a very advanced mainline airliner engine, which will cause a strong backlash from the traditional top three, and it will not be beneficial to Tianfeng Technology.

Wait a while, this is Li Tianfeng's idea, so he has not been in a hurry to launch more advanced engines, but has been maintaining the production of turbofan 16, turbofan 17 and turbofan 18 engines, and these three engines can also sell hundreds of units every year, and the results are not bad.

In fact, in Sun Xiaoping's heart, 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: "Let's go, let's take a look at the turbofan 30 engine." ”

As you can see, on the final assembly bench in the distance, the turbofan 30 engine is very conspicuous, and it stands out from the crowd!
