Seeing Ma Delong coming over, Li Tianfeng smiled.

Ma Delong came over happily, held Li Tianfeng's hand tightly, and said happily: "Mr. Li, the test flight of our ARJ21 regional airliner was a complete success, thank you for providing us with such an excellent engine." ”

Li Tianfeng said: "Mr. Ma is polite, this is also the first flight of our turbofan 17 engine, and I am as happy as you." ”

The two shook hands tightly, and Li Tianfeng said again: "Mr. Ma, congratulations!" The ARJ21 regional airliner with a new engine is very good for me to fly this test flight. ”

Ma Delong said: "Wait a little longer, the test flight data will come out, but even if you don't look at these data, according to my experience, this test flight will definitely be very successful." ”

The relationship between the two was not bad, and the test flight was very smooth, the two shook hands tightly, and said happy and polite words to each other.

At this moment, Li Tianfeng and Ma Delong have become the absolute focus, if it weren't for everyone around, the reporters in the distance wouldn't be able to come, I was afraid that these reporters would come around and take pictures frantically, and then, the next day, the major media would have photos of the two shaking hands.

In the distance, many people faintly saw the situation here, many people were still stretching their necks and looking over here, and many people were talking in low voices.

"That person just now is Mr. Ma of Shangfei, Mr. Ma shook hands with the young man, who is that young man!"

"Yes, that man looks so young, who is that!"

"You don't know this, this is Li Tianfeng, the boss of Tianfeng Technology Company!"

"Tianfeng Technology Company, which developed the turbofan 17 engine?"

"Ahh He is Li Tianfeng! ”

Quite a few people, while talking in a low voice, exchanged heads and ears, and stretched their necks. Looking over here on tiptoe, many reporters were still holding cameras and carrying camera equipment, squeezing hard in this direction.

But. Before these reporters squeezed over, everyone saw that the people of Tianfeng Technology Company and a large group of people from COMAC Company were like stars and moons, embracing Li Tianfeng and Ma Delong and walking into the distance.

Some reporters wanted to capture Li Tianfeng and Ma Delong in the center of the crowd, but there were too many people, and these reporters worked hard. But he only photographed the periphery, and at most only Li Tianfeng's back.

………

At the luncheon, COMAC was also very polite, a little like a celebration luncheon, in a famous five-star hotel in the East China Sea, not only invited people from Tianfeng Technology Company, but also invited some people from the domestic aviation industry and some people from the competent authorities. As well as quite a few airlines participated.

Li Tianfeng didn't show much limelight, and his performance was relatively low-key. Ma Delong came over to toast in person, and Li Tianfeng stood up and drank with Ma Delong with a wine glass.

It can be seen that Ma Delong has a lot of wine and has drunk a lot of wine, but he is only full of red light. But he is very clear-headed, talks and laughs freely, is exquisite, and has a good deal to do.

Li Tianfeng smiled and thought in his heart. In the future, you should drink a little more leisurely with Maderon, this guy typically belongs to the barrel level, and drinking white wine is similar to drinking plain water.

After the luncheon, there was a lunch break, at half past three in the afternoon, in this hotel, in a conference room, there was a more professional test flight summary meeting.

It should be that with a professional nature, there are not many people who participated, Tianfeng Technology Company, COMAC, and several aviation industry people who were invited to participate, as well as executives of some airlines, about 20 or 30 people.

Because it is a five-star business conference room, it is very luxurious, Li Tianfeng and Sun Xiaoping, Zeng Qinghai, and Liu Wei participated on behalf of Tianfeng Technology Company.

The meeting was hosted by COMAC, which first made a brief speech, introduced the basic situation, and then shared professional data, and presented the data of the test flight in front of everyone through the projector.

The data has obviously been sorted out, and it is clear at a glance that some of the main parameters, what is the qualified value, what is the actual value, is clear and clear at a glance.

Seeing these data, all of them are normal, many of them are still very good, many participants are talking in low voices, and in the conference room, there are bursts of whispered discussions.

A participant of an airline stood up, Ma Delong knew, this was an executive of a famous domestic airline, so, Ma Delong said: "Mr. Duan, what questions do you have?" ”

This Mr. Duan said: "Mr. Ma, the test flight data you released is relatively comprehensive and very clear and understandable, but I still have a little doubt. ”

Mr. Duan said politely: "Fuel consumption is obviously low, is there a little problem, is it possible to write it wrong." ”

When the data came out and was given to Ma Delong, Ma Delong naturally looked at it carefully and carefully, and also found this, and specially asked.

So, Ma Delong said: "Mr. Duan, the data is definitely not wrong, we have carefully checked, the fuel consumption is indeed relatively low, the ARJ21 passenger plane we tested is also empty, equipped with the turbofan 17 engine of Tianfeng Technology Company, which is 13% lower than the fuel consumption of our previous ARJ21 airliner, I dare to guarantee that this data must be true." ”

The ARJ21 passenger aircraft has been mass-produced, and all the ARJ21 passenger aircraft previously manufactured by COMAC are equipped with GE's CF34-10A engine, which shows that the fuel utilization rate of the turbofan 17 engine is higher than that of GE's CF34-10A engine, which is more fuel-efficient.

Fuel consumption is reduced by 13%!

Representatives of a number of airlines who participated in the meeting, we looked at each other, as airline people, naturally know that fuel consumption is the largest one, each flight of a flight, if you can save 13% of fuel, that year, this saves a lot of money, invisibly, your company's profits will directly rise a few points, invisibly, but also increase competitiveness.

In the current aviation industry, the competition is fierce, and the fuel consumption is reduced by 13%, which is the gold content, and the representatives of these airlines know better than anyone else.

These delegates quietly glanced at each other, and their eyes could not hide their excitement and excitement!

Mr. Duan, who spoke just now, couldn't help but feel excited and happy in his heart when he saw Ma Delong's affirmative answer, and said in his heart, great!

Mr. Duan said: "Mr. Ma, the fuel consumption of the ARJ21 passenger aircraft is 13% lower, how did you do this, did you upgrade the technology of the aircraft, or?" ”

Ma Delong smiled happily, Ma Delong naturally knew the 13% gold content, and after a happy smile, Ma Delong said: "Mr. Duan, it's not a secret, this is mainly due to the turbofan 17 engine of Tianfeng Technology Company, this engine has the characteristics of ultra-low fuel consumption, ultra-low noise and ultra-low emissions. ”

Mr. Duan looked at Li Tianfeng and said in surprise: "Mr. Li, it's really like this!" ”

Li Tianfeng smiled happily, especially when he saw that the representatives of these airlines were looking at him, Li Tianfeng said: "Our turbofan 17 engine, indeed, as Mr. Ma said, has the characteristics of ultra-low fuel consumption, ultra-low noise and ultra-low emission......

Taking the opportunity, Li Tianfeng briefly introduced his own engine, especially a series of advantages of this engine, such as ultra-low fuel consumption, ultra-low noise, ultra-low emission characteristics, as well as ultra-high safety, maintainability, long life, super good low-speed performance, etc., made a brief introduction.

After listening to the introduction, the whole conference room was silent.

No wonder!

No wonder the turbofan 17 engine is so good, it turns out to take so many excellent designs!

A representative of the airline stood up and said: "So that's the case, you can be said to have really worked hard, and the design is so comprehensive, the turbofan 17 engine, not only ultra-low fuel consumption, fuel consumption is reduced by 13%, I think the noise is also very low." ”

In terms of noise, there are also data monitored during test flights, and in general, the noise of the turbofan 17 engine is at least a few decibels lower than that of similar turbo engines.

Don't underestimate such a small few decibels, you may not have any intuitive feelings, but once you take the ARJ21 passenger plane, this comfort is more obvious.

"Mr. Li, you guys are amazing, this time, my old Yuan is completely convinced."

Li Tianfeng has a little impression of this middle-aged man who calls himself "Lao Yuan", who seems to be an executive of a large domestic aviation industry company.

Li Tianfeng said: "Mr. Yuan, I have won the award." ”

The meeting was very successful, more than an hour of meeting, the atmosphere was very good, Li Tianfeng gradually became the protagonist, the participants in the meeting, the turbofan 17 engine spoke highly of it.

Although Li Tianfeng stole the limelight, Ma Delong was not angry at all, on the contrary, he was happy, and his heart was full of joy.

The turbofan 17 engine is so good, even beyond the same kind of imported engines, their own ARJ21 passenger aircraft is also stained, look at this situation, soon they will usher in new orders, representatives of these domestic airlines, it seems that not only the turbofan 17 has shown great interest, but also showed great interest in their ARJ21 passenger aircraft.

Ma Delong happily looked at Li Tianfeng, who was speaking, and thought in his heart, Tianfeng Technology Company is amazing, and cooperating with Tianfeng Technology Company will be the proudest and wisest thing among the series of things he has done in office.
