Seeing Sun Xiaoping, Li Tianfeng smiled, "Mr. Sun, please take a seat, it's about the development of a new engine." ”

Li Tianfeng guessed right, and sure enough, Sun Xiaoping said: "Boss, it's our new engine, the design outline has come out, I want you to help check it." ”

Although he is an academician, Sun Xiaoping is very modest in front of Li Tianfeng, Sun Xiaoping knows Li Tianfeng's technical level, Li Tianfeng's technical level is far above himself, and in Sun Xiaoping's opinion, it is completely unfathomable!

Previously, Li Tianfeng deployed the development task of a new engine to Sun Xiaoping, and it was the second-generation large-signal turbofan engine.

Tianfeng Technology's first generation of turbofan engines have turbofan 16, turbofan 17, turbofan 18, a total of three, these three engines have been produced thousands of units, a total of tens of millions of hours in the flight world, has been performing well, especially the safety is very high.

The second-generation turbofan engine mainly has two engines, turbofan 21 and turbofan 30, which are better in terms of fuel consumption, noise, emissions, etc., and of course, the safety is also very high.

The turbofan 21 has a thrust grade of 10,000 pounds, and the thrust ranges from 1 or 2,000 pounds in the small power state to 10,000 pounds in the maximum power state, which is mainly used for small passenger aircraft, regional airliners, small business jets, etc., and has a very good market prospect.

The turbofan 30 engine, with a thrust level of 100,000 pounds and a maximum thrust of 150,000 pounds, is mainly used for large aircraft, such as large civil airliners Airbus A380 and Boeing 747, as well as Y-30 and Y-25 transport aircraft.

Among the second-generation turbofan engines, there are turbofan engines with huge thrust and 100,000 pounds of thrust, such as turbofan 30 engines, and turbofan 21 engines with relatively small thrust and outstanding performance. But there is no engine in the middle thrust class.

At present, it is mainly supported by the turbofan 16 engine, which has a maximum thrust of 50,000 pounds and a rated thrust level of 20,000 or 30,000 pounds, mainly used for Airbus A320 and Boeing 737. C919 and other passenger aircraft, the annual demand is about three to five hundred.

That is to say, in the 150-seat mainline airliner market, the turbofan 16 engine does not occupy a large share, as an excellent aero engine designer, Sun Xiaoping has long wanted to design a more advanced, better comprehensive performance of the engine.

Last time, Sun Xiaoping mentioned this matter to Li Tianfeng, and Li Tianfeng thought about it. also agreed, but did not give guidance on the design, and Sun Xiaoping was all in charge.

Now, the design and technical outline of this new engine has come out, this engine, using the second-generation core engine technology of Tianfeng Technology Company, the technical level and turbofan 21 and turbofan 30 engine, the same technical level.

Li Tianfeng took over the design technical outline. Li Tianfeng looked at it with great interest and looked at it more carefully. Sun Xiaoping waited patiently on the sidelines.

During the whole process, Li Tianfeng asked some questions from time to time, Sun Xiaoping answered them one by one, and it took a short time to read them, Li Tianfeng said with satisfaction: "There are no problems overall, but some details can be further improved." As ......"

Li Tianfeng pointed out the areas that needed to be improved and perfected one by one, and Sun Xiaoping wrote them down one by one, waiting for further improvement.

The new engine is positioned as a civil trunk airliner, meeting the needs of large passenger aircraft from 150 seats to 400 seats. As for passenger aircraft with more than 400 seats, they can be powered by turbofan 30 engines.

According to the design outline just now, this engine has a thrust rating of 50,000 pounds, and the thrust range is from 10,000 pounds to 70,000 pounds, which is a relatively large span, and obviously, it will use a very advanced digital fuel conditioning system. The maximum thrust of 70,000 pounds can be met even by a large passenger aircraft with 400 seats.

Such an engine, the technical level and turbofan 21 and turbofan 30 engine are the same, if successfully developed, it will be one of the most advanced large-channel turbofan engines in the world, as for the price, it must be more expensive than the turbofan 16 engine.

Li Tianfeng said: "Mr. Sun, the design and development of this engine mainly depends on you. ”

Sun Xiaoping said: "Boss, don't worry. ”

With this design technical outline that needed to be improved and modified, Sun Xiaoping happily walked out of Li Tianfeng's office.

………

Tianfeng Technology Company.

In the reception room, Li Tianfeng was chatting happily with a middle-aged man, and next to the two, there were some escorts.

Tianfeng Technology Company has Xu Lilong and Liu Wei and several other people, this middle-aged man also brought a lot of people, everyone centered on Li Tianfeng and this middle-aged man, the atmosphere is good, and from time to time there are bursts of relaxed laughter.

This middle-aged man is not simple, one of the most powerful airlines in China, Song Jie, the president of Air China, came to Tianfeng Passenger Aircraft Company with Song Jie, a vice president of Air China, and several other entourage.

Li Tianfeng didn't think that his new large passenger plane was so popular that it might usher in the first user of this passenger aircraft.

Song Zhidao: "Mr. Li, you took us to visit the factory just now, and you really live up to your name, and you are worthy of being the top enterprise in the domestic aviation industry." ”

During the visit just now, Song Jie, who was accustomed to seeing big scenes, couldn't help but praise it, and now, he talked about it again.

Li Tianfeng was happy for a while, "Mr. Song, if it is two years later, I will be able to take you to our aviation city to have a look, which is bigger, more modern, and more majestic than our current factory." ”

Song Jie said: "Mr. Li, if you have the opportunity, we will definitely go to your aviation city to have a look, at present, in China, your aviation city is very famous." ”

Tianxin Base Aviation City, which is under construction, has been greatly famened with the announcement of Tianfeng Technology Company that a new large passenger aircraft will be produced there.

Song Jie took the initiative to say: "Mr. Li, although we can't visit the airport city for the time being, we can discuss your big passenger plane." ”

Li Tianfeng said: "Mr. Song, are you interested in our new passenger plane?" ”

Song Jie smiled and said: "Of course, not only interested, but also very interested, I think, no matter which aviation company the CEO, I think will be very interested." ”

The new airliner announced on the official website of Tianfeng Technology Company, how dazzling, how outstanding, completely subverts the design of traditional civil airliners, not to mention, fuel consumption, noise, emissions, and maintenance costs are so low, it is estimated that Song Jie is not the only one who is interested.

It is estimated that many people are paying attention to this new passenger plane, but Song Jie is ready to be the first person to eat crabs, and he is the first to take the initiative to come to the door, and expresses his intention to order this new passenger plane.

As for whether the passenger aircraft is still in the development stage, whether it will fail to develop, Song Jie is not worried at all, in the development history of Tianfeng Technology Company, there seems to be no word "failure".

Li Tianfeng said: "Mr. Song welcomes you to order our new passenger aircraft, if you order our new large passenger aircraft, you will become the first user of this large passenger aircraft." ”

Song Jie said: "Mr. Li, then we are deeply honored, in addition, I heard that this passenger plane is called 'Ark 600', is it true." ”

Li Tianfeng said: "It is indeed called 'Ark 600', of which 600 represents the 600-seat class, and our aircraft has several cabin layouts, including 528 seats, 596 seats, and 618 seats. ”

The size of the cabin must be the same, the number of seats is different, but the spacing is different, the 528-seat class is definitely more business class, the first class is more, and the 618 seats are definitely economy class-based.

Song Jie said: "It is worthy of being a big plane at the giant level, the Ark 600 passenger plane can carry 618 passengers, such a passenger plane, I don't know how much it costs?" ”

The aircraft is still under development, Li Tianfeng made a cost budget early, the cost of the Ark 600 passenger aircraft is definitely cheaper than the Airbus A380, cheaper than the Boeing 747, but the performance is much outstanding, and the price is definitely more expensive than the Airbus A380 passenger aircraft.

At present, the price of the Airbus A380 passenger aircraft is about 300 million US dollars, which is equivalent to about 2 billion yuan. Ark 600 airliner......

Li Tianfeng pondered a little and said slowly: "Mr. Song, our Ark 600 passenger aircraft will be the most advanced and best super-large civil airliner in the world, naturally more expensive than the Airbus A380 passenger aircraft, I hope you can understand." ”

Song Jie nodded and said, "Of course, we can understand this. ”

Li Tianfeng said: "The international price of the Ark 600 passenger aircraft is 2.6 billion yuan, and Mr. Song, you are our first user, and the price of each aircraft is 2.5 billion." ”

2.5 billion a plane!

It's expensive!

Song Jie thought about it, and then said: "Mr. Li, the Ark 600 passenger aircraft is really as good as you advertised, compared with the Airbus A380 passenger aircraft fuel consumption is more than 40% lower, and the daily maintenance cost is more than 30% lower, is it true?" ”

If these data are true, although the price of 2.5 billion is a little high, but only the first investment is a little larger, the later economic benefits can gradually appear, if the real calculation, in the whole life cycle of the passenger aircraft, more cost-effective.

After thinking about these clearly, Song Jie said: "Mr. Li, if these can be written into the order contract, we will order 20 Ark 600 passenger planes." ”

Li Tianfeng smiled: "Of course, we will write these things in the order contract." ”

20 Ark 600 airliners!

50 billion yuan!

Suddenly, everyone in Tianfeng Technology Company was overjoyed, and Li Tianfeng stood up with a happy face and took the initiative to stretch out his right hand.

Song Jie also stood up and shook hands with Li Tianfeng enthusiastically, and the right hands of the two of them were strongly clasped together!
