After a brief tour of the production line, the group came to the conference room, and Kangchi finally said the purpose of his trip.

When he heard that Kang Chi wanted them to help with the improved version of the OEM 20, Dong Jun almost suffered a cerebral hemorrhage on the spot......

Coquettishly took their drawings and said to study them, and then threw them back with a backhand and let them do the OEM?

Who can stand this kind of sassy operation?

Dong Jun glanced at Pei Hengsheng and saw that he was not only calm, but also glanced at him, so he had to forcibly control his anger and try not to get mad on the spot.

After taking the hard drive from Kangchi with a straight face, Dong Jun opened the drawings on the spot, and several other people in the venue, including Cai Yaobin, couldn't help but come up to see what Kangchi's so-called Yun 20S looked like.

At first glance, everyone's first reaction was: Isn't this special Yun 20?

But soon, Dong Jun discovered the biggest difference between it and Yun 20.

Although in this drawing, only the fuselage has no engine, but through the design of the wing and the layout of the line, he immediately discovered that this so-called Y-20S has only two engines!

Then he was completely confused.

What kind of immortal improvement is this?

With only two engines, it will definitely be able to fly, but it is estimated that it can only take off empty......

The Y-20 is a transport plane, and it has to carry dozens of tons of things inside!

Does he think the fat girl is too good at pretending, or does he not know how to build an airplane at all?

Hold on, hold back......

Dong Jun took a deep breath, once again forcibly suppressed the emotions that were about to go wild at any time, and said in a deep voice: "Mr. Kang...... Your design doesn't make sense, right? ”

"Y-20 is a transport plane, how can you fly with only two engines? Can you build an engine that is twice as tall as the Turbofan 20? ”

Cai Yaobin and Pei Hengsheng, who couldn't understand the drawings, were also stunned after hearing Dong Jun's questioning, and then looked at Kang Chi with the same strange gaze as Dong Jun.

"Well, it's actually more than twice as much, I plan to build a turbofan-30 with 50 tons of thrust."

50 tons of thrust ?!

Hearing Kang Chi's words, the people present were stunned again.

Seeing this, Kang Chi hurriedly added: "If you mind me using your name, I can change my name." ”

“……”

Is this a question of whether it is a name or not?

Dong Jun quickly thought about the possibility of a 50-ton thrust engine.

First of all, this thing does have a trick.

As early as 1995, the GE90 thrust was as high as 84,700lbf (37.6 tons), and later derivative models were stronger than the other, and GE90-115B broke the Guinness World Record with a maximum thrust of 56.9 tons in the ground bench test in 2001, becoming the world's largest thrust aero engine.

Later, this stick was taken over by GE9X, and its thrust was 61 tons.

However, after all, the GE series engine is tailor-made for large civil airliners, and may not be able to withstand the harsh working conditions of military aircraft, because large thrust means large bypass ratio, that is, large diameter, like the diameter of the inlet channel of GE9X, which is as high as 4.5 meters, which is not conducive to maintaining the ground clearance of the engine, and is easy to get involved in sand and gravel, so it is more difficult to pick the airport.

But do you say it doesn't smell good?

Of course it's fragrant!

Regardless of whether the 50-ton thrust engine proposed by Kangchi can be used in military transport aircraft, and regardless of its fuel consumption and other performance, as long as it can be made, it will be a huge boost to the development of China's aviation industry.

Especially in the field of civil aviation.

For a long time, civil airliners have basically been monopolized by the two major companies of the West, Boeing and Airbus, and the planes that Huaguo bought before are not counted, after all, the money has been spent......

But if you look backwards, according to statistics, China will need at least about 8,560 new passenger planes in the next 20 years.

Among them, there are 350 regional passenger aircraft, 6,470 narrow-body single-aisle trunk passenger aircraft, 1,550 wide-body passenger aircraft, and 190 cargo aircraft, with a total value of about 11 trillion.

And this is just the Chinese market.

By monopolizing the global civil airliner market, it is conceivable how nourishing Boeing and Airbus are living.

If we don't make such a big piece of cake, we will always be able to watch others eat it, and even we will be the one who is eaten.

In order to break this monopoly and bottleneck, COMAC came into being.

The development route of COMAC is also down-to-earth from small to large, and the first to build is the regional airliner ARJ21.

However, regional airliners pull fewer people, small range, cheap unit price, and the market demand is not large, so it is not profitable.

So later there was C919, which has been approved by many countries for airworthiness, although it is known as a domestic large aircraft, but in fact it is only a narrow-body single-aisle trunk airliner.

The so-called trunk airliner is a short- and medium-haul route with a maximum passenger capacity of less than 200 people and a flight mileage of less than 6000KM.

However, the demand for this passenger aircraft is also the largest.

So far, the monopoly and bottleneck of passenger aircraft have actually been solved by more than half.

The rest is a large wide-body passenger aircraft like the A380, which has a maximum passenger capacity of more than 300 and can carry long-distance transoceanic flights, which is also the top product of the aviation industry.

Its demand seems to be small, the quantity is only about 18%, but it can't withstand the high unit price of two or three of its planes.

However, the R&D and manufacturing of this large wide-body passenger aircraft is too difficult, even Huaguo is not so confident, so in the end, the old Maozi with a relatively strong aviation technology background was pulled, and the two sides cooperated to develop CR929.

But the two sides bumped and bumped for more than ten years, and finally broke up, and the CR929 project became the C929 project, and the first flight date became unknown.

Therefore, in the case that Kangchi has already developed the T1200 super carbon fiber material, if a 50-ton thrust turbofan aviation engine is made, then the problem of the C929 project alone will be solved at least half.

But the question is, how can this thing be so easy to do?

The design thrust of the CJ-2000 engine of the C929 is 35 tons, and it has made the commercial aviation head bigger for so many years, and you are 50 tons here.

Isn't the step too big?

"Mr. Kang, it's not that I don't believe you, and then it doesn't matter whether this engine is suitable for Yun 20 for the time being, after all, we are not afraid of trial and error in scientific research." Dong Jun said helplessly, "But the question is how long it will take you to get this step like this?" The engine hasn't started yet, so let's build the fuselage, isn't it too anxious? Our capacity is also limited......"

"Capacity is not an issue." Kang Chi directly retorted, "Mr. Cai is here, if you delay the delivery of Yun 20 because you helped me build Yun 20S, Mr. Cai will definitely not blame you, right, Mr. Cai?" ”

"Huh? Well...... Right! ”

“……”

"Also, I'm not prostituting you for nothing, how much will it cost to help me build the fuselage, I'll pay you a lot of money, as for how long it will take for my engine to be built......"

Kang Chi's mind quickly turned, and he said, "Anyway, it must be faster than you guys to build the fuselage!" ”

Sure enough, as Kang Chi expected, after hearing him say this, Dong Jun couldn't help but retort at the beginning: "This is impossible!" ”

"Don't believe me? Why don't we compete and see who can build it first? ”

"Compare to compare!"

Yes, yes, that's what you want!

Seeing Dong Jun, who had already been set, Kang Chi was also relieved.

Once this person is provoked, he is not afraid that he will delay his plan.

In order to take another insurance, Kangchi took the initiative to propose: "Since it is a competition, why don't you set up some small prizes...... What do you want? ”

"What do we want?"

Dong Jun hesitated for a moment, and then finally mustered up the courage to say, "If you lose, give us the drawings of the silver crane to learn from." ”

Kang Chi suddenly smiled.

Sure enough, although they didn't have anything on the surface, they always had a pimple in their hearts for the matter of transporting 20 drawings, and the first thing they thought of after finding an opportunity was to have a tooth for a tooth to get back face......

"No problem, but if you lose, you have to shout three words in front of everyone in your project department: Mr. Kang is awesome!"

As soon as these words came out, everyone was immediately embarrassed.

This......

Is it so shameless?

In fact, Kang Chi is also quite embarrassed, but he knows that for these scientific researchers, nothing is more important than face, so compared with substantive rewards and punishments, this kind of thing involving face is more lethal.

As long as he is not embarrassed, it is someone else who is embarrassed!

Sure enough, when Dong Jun imagined that picture, goosebumps all over his body suddenly rose.

"Let's ...... Can you change it? ”

"Throwing in the towel so soon?"

"It's not...... I...... We have no opinion! ”

——

After leaving Xifei, Cai Yaobin immediately couldn't help but give Kang Chi a thumbs up, and said with a smile: "Mr. Kang is awesome!" I don't know, I thought you got the true biography of Academician Zhang Dayuan. ”

"Haha, this trick was indeed learned from Academician Zhang."

Kang Chi then smiled and told Cai Yaobin about Zhang Dayuan's crazy monster pulling operation when he was engaged in EUV light source, and Cai Yaobin couldn't help laughing when he heard it: "He really can do it, full of flavor!" ”

But after laughing, Cai Yaobin couldn't help but be a little worried: "But are you sure you can really do it so quickly?" ”

"Don't underestimate Dong Jun and them, the team that can make great luck so quickly really has to be more energetic, maybe it will be made for you in a month or two......"

"After all, the production line of Yun 20 is ready-made, even if you change it a lot, it is also changed on the basis of Yun 20, and most of them can be directly applied."

"What? You don't believe me either? ”

"That's not ...... It's just that it feels a little unrealistic......"

"I just don't believe it."

“……”

After Kangchi left, Dong Jun and others immediately carried out a detailed analysis of the design plan given by Kangchi.

After all, a large aircraft is not ordinary equipment, this is a very systematic project, and any change will affect the whole body.

Although the Y-20S was only changed from four engines to twin engines, it sounds like it is just two engines missing, and it may look similar in appearance, but in fact, there are a lot of small changes involved.

Just now, Dong Jun and the others just took a rough look, and did not carefully study whether the changes to each design were reasonable.

With the deepening of research, the hearts of Dong Jun and Chi Jinliang gradually began to become more and more shocked.

More than a dozen engineers in their project team got together to study for a long time, but they didn't find anything wrong with this drawing.

After carefully going through the drawings, Chi Jinliang couldn't help but rub his slightly dry eyes, and exclaimed: "Whether we can find out the problem or not, it can be seen from this drawing alone that he has basically eaten our Yun 20 drawings......"

"No wonder he didn't ask anything when he first visited the workshop."

"It's not a problem." Dong Jun shook his head with a solemn expression: "After all, it is possible to build an EUV lithography machine, and I never think it is difficult for him to eat through the drawings." ”

But the problem is, learning and using it flexibly are completely different things, how can he get through the drawings so quickly and complete the improved design? Is it really that someone's perception is so terrible......"

"Hey...... It can only be said that people are more popular than people, and now no one in the Chinese scientific research community knows that he is a freak, and it seems that there is no bottleneck in any field of this pervert, and once he makes a move, the wisest decision for others is to quickly pick up the bucket and run away...... I heard that the few camera lenses in the small book are ready to fully withdraw from the Huaguo digital camera market this year...... If it weren't for Daqin Optics not being able to enter the European M market, these companies would have to peel off their skins if they didn't die. ”

"Well, I've heard about that, too." Dong Jun sighed, "Fortunately, this time, depending on what he means, he should only be responsible for the research and development of the engine, and the fuselage will still be handed over to us, so even if he really does it, we should not be as miserable as Hafei......"

"Ahem...... Mr. Dong, you shouldn't just admit defeat, right? ”

"Throw in the towel?" Dong Jun was stunned for a moment, and then immediately cheered up and said, "I didn't say that, I just admitted that with his strength, it is indeed possible to make a high-thrust engine." ”

"But no matter how perverted he is, he won't be faster than we can build the fuselage, right? From today onwards, half of the people in the project department will be dispatched to help him build the fuselage, and I don't believe that this can be lost! ”

After hearing this, Ji Jinliang was immediately surprised: "Half of the people?!" ”

"Yes, anyway, didn't Cai Yaobin also express his position just now, delaying the delivery speed of Yun 20, and it's none of our business, I want to see if this so-called Yun 20S is worth it for us to delay the delivery of Yun 20."

“……”

——

After leaving Xifei, after more than 8 hours of flight, Kangchi and their team finally came to Hafei.

It can only be said that the cruising speed of Yun-12 250Km/h is really slow, and it will land once to refuel in the middle of the 2000-kilometer voyage, which makes Kangchi have a higher sense of expectation for Yinhe to get the trial permit.

The main reason for coming to Hafei this time was that Cai Yaobin helped Huaguo Aviation Industry Group test Kangchi's attitude on the phone.

In fact, it is also very simple, it is already a trend for electric rotorcraft to replace traditional helicopters, Hafei and Changhe two helicopter manufacturing bases, it seems a little embarrassing, such a large production base, so many mouths to eat, it must be best not to shut down.

Therefore, the aviation industry wants Kangchi to use the manufacturing technology and equipment of electric aircraft to invest in Hafei and Changhe, and change them into the manufacturing base of Yinhe.

In fact, Kangchi has had this idea before, after all, there is a ready-made manufacturing base and manpower, which is definitely beneficial to the mass production of Yinhe.

But how to say it......

After all, they are state-owned enterprises,

If Kangchi takes the initiative to propose, it will have a somewhat bad impact, and it is easy for people to think that he is embezzling national assets.

And when they take the initiative, the meaning is different.

If Kangchi does not provide technology, they are about to be eliminated by the times, so how can they embezzle?

And when they take the initiative, Kangchi can also occupy more initiative, and have a greater say in the two companies in the future, so as to avoid some disobedient people hindering his plan.
