Chapter 260 The True Biography of Academician Zhang

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

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

Chi took their drawings coquettishly and said he would study them, then threw them back and asked them to do the work?
Who can stand this kind of sexy operation?
Dong Jun glanced at Pei Hengsheng and saw that he was not only calm but also winking at him, so he had to control his anger and try not to get angry on the spot.

After taking the hard drive from Kang Chi with a straight face, Dong Jun opened the drawing on the spot. Several other people in the venue, including Cai Yaobin, couldn't help but get closer and wanted to see what Kang Chi's so-called Yun 20S looked like.

At first glance, everyone’s first reaction is: Isn’t this just Lucky 20?
But soon, Dong Jun discovered the biggest difference between it and Yun 20.

Although this drawing only showed the fuselage without engines, through the design of the wings and the layout of the lines, he immediately discovered that this so-called Y-20S actually had only two engines!
Then he was completely confused.

What kind of magical improvement is this?
With only two engines, it will definitely be able to fly, but I guess it can only take off with empty weight...

The Y-20 is a transport aircraft, and it has to carry dozens of tons of stuff 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 it, hold it...

Dong Jun took a deep breath, once again suppressed the emotion that was about to go violent at any moment, and said in a deep voice: "Mr. Kang... your design is unreasonable, right?"

Then came the C919. Although this passenger aircraft that has obtained airworthiness licenses from many countries is known as a domestically produced large aircraft, it is actually just a narrow-body single-aisle mainline passenger aircraft.

其中支线客机350架、窄体单通道干线客机6470架、宽体客机1550架、货运飞机190架，总价值约11万亿，如果加上保养维修之类的售后服务市场，则至少还得再加个5万亿。

Cai Yaobin and Pei Hengsheng, who could not understand the drawings, were stunned when they heard Dong Jun's question, and then looked at Kang Chi with the same strange eyes as Dong Jun.

Regardless of whether the 50-ton thrust engine proposed by Kangchi can be used on military transport aircraft, or whether its performance such as fuel consumption is good, as long as it can be built, it will be huge for the development of China's aviation industry. advancement.

"The Y-20 is a transport aircraft. How can it fly with only two engines? Can you build an engine that is twice as powerful as the Turbofan 20?"

First of all, this thing does have a head start.

If we don’t take on such a big piece of cake, we will always have to watch others eat it, or even be the one being eaten.

Therefore, after Kangchi has developed the T1200 super carbon fiber material, if it develops a 50-ton thrust turbofan aircraft engine, at least half of the problems of the C929 project will be solved.

For a long time, civil aviation passenger aircraft have been basically monopolized by the two major Western companies, Boeing and Airbus. The aircraft purchased by China in the past do not count. After all, the money has been spent...

At this point, the monopoly and bottleneck of passenger aircraft has actually been solved by more than half.

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

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

However, the two sides had been bumping into each other for more than ten years, and finally broke up on bad terms. The CR929 project also became the C929 project, and the first flight date became unknown.

However, regional passenger planes carry few people, have short range, cheap unit prices, and low market demand, so they are not profitable.

Is this a matter of name or not?

But do you think it smells good?
Of course it smells good!

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

However, it is too difficult to develop and manufacture such a large wide-body passenger aircraft. Even China is not so confident, so in the end it roped in an old man with a strong foundation in aviation technology, and the two parties worked together to develop the CR929.

"..."

And this is just the Chinese market.

But if we look back, according to statistics, China will need at least about 20 new passenger planes in the next 8560 years.

Especially in the field of civil aviation.

As early as 1995, Tongyong Electric Aviation Engine Company produced the GE90 with a thrust as high as 84700lbf (37.6 tons). Later derivative models were stronger than the last. In the ground bench test in 90, the GE115-2001B achieved a thrust of 56.9 The maximum thrust of tons broke the Guinness World Record and became the world's most powerful aerospace engine.

The development path of COMAC is also down-to-earth, from small to large. The first one built is the regional passenger aircraft ARJ21.

Seeing this, Kang Chi quickly added: "If you mind if I use your name, I can change it."

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

By monopolizing the global civil aviation market, you can imagine how comfortable Boeing and Airbus' lives have been.

"Production capacity is not a problem." Kang Chi retorted directly, "Mr. Cai is here. If you delay the delivery of the Y20 because you help me build the Y20S, Mr. Cai will never blame you, right Mr. Cai?" ?”

Its demand seems to be small, with a quantity of only about 18%, but it cannot withstand the high unit price of one machine compared to two or three.

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

Later, this big stick was taken over by GE9X, which has a thrust of 61 tons.

Is the step too big?
"Mr. Kang, it's not that I don't believe you. I don't care whether this engine is suitable for transporting 20 vehicles. After all, we who are engaged in scientific research are not afraid of trial and error." Dong Jun said helplessly, "But the problem is your pace. How long will it take to build such a big engine? Isn’t it too impatient to ask us to build the fuselage before we even start working on the engine? Our production capacity is also limited..."

50 tons of thrust? !

"Also, I'm not asking you for nothing. How much does it cost to help me build the fuselage? I'll pay you every penny. As for how long it will take to build my engine..."

"Huh? Um...right!"

The design thrust of the CJ-929 engine of the C2000 is 35 tons. Even though it has been a big improvement for Commercial Aircraft for so many years, it is 50 tons here.

"..."

However, the GE series engines are tailor-made for large civil aviation aircraft after all, and may not necessarily be able to withstand the harsh working conditions of military aircraft, because large thrust means large bypass ratio, that is, large diameter, like the air intake of GE9X The diameter of the tunnel is as high as 4.5 meters, which is not conducive to maintaining the ground clearance of the engine, and it is easy to get involved in sand and gravel, so it is more suitable for airports.

The rest are large wide-body passenger aircraft like the A380, which have a maximum passenger capacity of more than 300 and are capable of long-distance transoceanic flights. They are also the top products of the aviation manufacturing industry.

Hearing Kang Chi's words, everyone present was stunned again.

The so-called mainline passenger aircraft refers to short- and medium-distance routes with a maximum passenger capacity of less than 200 people and a flight mileage of less than 6000KM. In the field of civil aviation passenger aircraft, they are actually only medium-sized passenger aircraft.

Kang Chi thought quickly and said, "Anyway, it will definitely be faster than you at building the fuselage!"

As expected by Kang Chi, after hearing what he said, Dong Jun couldn't help but retort: ​​"This is impossible!"

"Don't believe it? How about we have a competition to see who can build it first?"

"Compare!" Yes, yes, this is the effect we want!
Seeing Dong Jun who was already hooked, Kang Chi was relieved.

Once this person falls into the trap of provoking generals, he won't be afraid that he will delay his plan by subverting his plans.

In order to add another layer of insurance, Kang Chi took the initiative and suggested: "Since it is a competition, why not set up some small prizes... What do you want?"

"What do we want?"

Dong Jun hesitated for a moment, then finally plucked up the courage and said, "If you lose, give us Yinhe's drawings to learn from."

Kang Chi suddenly smiled.

Sure enough, although they seemed fine on the surface, they still had a knot in their hearts about the Yun 20 blueprint. When they found the opportunity, the first thing they thought of was to fight tooth for tooth to regain 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……

So shameless?
In fact, Kang Chi was quite embarrassed, but he knew that for these scientific researchers, nothing was more important than face, so compared to substantive rewards and punishments, things involving face were more lethal.

As long as he is not embarrassed, others will be embarrassed!

Sure enough, when Dong Jun imagined that scene, goosebumps suddenly appeared all over his body.

"Can we...can we change it?"

"Giving up so quickly?"

"No...I...we have no objection!"
-
After leaving Xifei, Cai Yaobin couldn't help but give Kang Chi a thumbs up and said with a smile: "Mr. Kang is awesome! If you don't know, I thought you had obtained the true biography of Academician Zhang Dayuan."

"Haha, I did learn this trick from Academician Zhang."

Kang Chi then laughed and told Cai Yaobin about Zhang Dayuan's crazy operation of pulling monsters when he was developing EUV light sources. Cai Yaobin couldn't help laughing and said: "It's really only he who can do this, it's full of Zhang flavor!"

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

"Don't underestimate Dong Jun and the others. If you really need to work hard to create a team that can achieve great luck so quickly, they might be able to create one for you in a month or two..."

"After all, the production line of Yun-20 is ready-made. No matter how big your changes are, they are still based on Yun-20. They can apply most things directly."

"What? You don't believe me either?"

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

"That's just because you don't believe it."

"..."

After Kang Chi left, Dong Jun and others immediately launched a detailed analysis of the design plan given by Kang Chi.

After all, a large aircraft is not an ordinary piece of equipment. It is a very systematic project, and any changes will affect the whole body.

Although the Y20S only changed from four engines to two engines, it sounds like it just lost two engines. The appearance may look similar when built, but in fact there are many small changes involved.

Just now, Dong Jun and the others only took a rough look and did not carefully study whether each design change was reasonable.

As the research deepened, Dong Jun and Chi Jinliang gradually began to feel more and more shocked.

More than a dozen engineers from their project team gathered together to study for a long time, but they couldn't find any flaws in this drawing.

After carefully going over the drawings, Chi Jinliang couldn't help but rub his slightly dry eyes and exclaimed: "No matter whether we can find the problem or not, we can see from this drawing alone that he cares about us." I have basically understood the Yun-20 blueprint..."

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

"This is not a problem." Dong Jun shook his head with a solemn expression: "After all, he can build an EUV lithography machine. I never think it is difficult for him to understand the drawings."

"But the problem is, learning and using it flexibly are completely different things. How can he understand the drawings so quickly and complete the improved design? Is anyone really so understanding?"

"Hey... I can only say that people are more annoying than others. Who in China's scientific research community doesn't know that he is a freak. This pervert seems to have no bottleneck in any field. And once he takes action, the wisest decision for others is to Hurry up and run away with the bucket... I heard that the camera lens manufacturers in Xiaoben are preparing to completely withdraw from the Chinese digital camera market this year... If Daqin Optics had not been able to enter the European M market, these companies Even if you don’t die, you have to peel off your skin.”

"Well, I've also heard about this." Dong Jun sighed, "Fortunately, judging from his intentions this time, he should only be responsible for the research and development of the engine, and the fuselage is still handed over to us, so even if he does it, we It shouldn’t be as miserable as Ha Fei…”

"Ahem...Mr. Dong, are you going to just give up?"

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

"But no matter how perverted he is, he can't be faster than we can build the fuselage, right? Starting today, half of the people in the project department will be assigned to help him build the fuselage. I don't believe that he can lose!"

Chi Jinliang was surprised after hearing this: "Half of the people?!"

"Yes, anyway, Cai Yaobin just expressed his position. It is none of our business to delay the delivery of the Yun-20. I want to see if this so-called Yun-20S is worth our delay in the delivery of the Yun-20."

"..."
-
After leaving Xifei, it took more than eight hours of flight before Kang Chi and the others finally arrived at Hafei.

It can only be said that the 250Km/h cruising speed of the Yun Twelve is really slow, and it has to land once for refueling during the 2000-kilometer journey. This makes Kangchi even more hopeful that Yinhe will get the sea trial license.

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

In fact, it is very simple. It is already a trend for electric rotorcraft to replace traditional helicopters. The two helicopter manufacturing bases of Hafei and Changhe seem a bit embarrassing. Such a large production base has so many mouths to eat. It would be best if it could not be shut down. .

Therefore, the aviation industry wants Kangchi to use its electric aircraft manufacturing technology and equipment to invest in Hafei and Changhe, and turn them into Yinhe's manufacturing bases.

In fact, Kangchi has had this idea before. After all, it has a ready-made manufacturing base and manpower, which will definitely be beneficial to Yinhe's mass production.

But what to say...

After all, they are state-owned enterprises.
If Kang Chi takes the initiative to propose it, it will have a somewhat negative impact and may easily make people think that he is embezzling national assets.

But when they take the initiative to bring it up, the meaning is different.

If Kangchi does not provide technology, they will soon be eliminated by the times, so why bother to embezzle it?
Moreover, when they take the initiative, Kang Chi will be able to take more initiative and have a greater say in the two companies in the future, preventing some disobedient people from hindering his plans.
