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 told them the purpose of his visit.
When Dong Jun heard that Kang Chi wanted them to help him manufacture the improved version of the Y-20, he almost had a cerebral hemorrhage on the spot…
Took their drawings and said he would study them, and then threw them back to them for manufacturing? Who can stand this kind of operation? Dong Jun glanced at Pei Hengsheng and saw that he was not only calm, but also winked at him, so he had to control his anger and try not to lose his temper on the spot.
After taking the hard drive from Kang Chi with a stern face, Dong Jun opened the drawings on the spot. Several other people in the meeting room, including Cai Yaobin, couldn’t help but come over to see what Kang Chi’s so-called Y-20S looked like.
At first glance, everyone’s first reaction was: Isn’t this the Y-20? But soon, Dong Jun discovered the biggest difference between it and the Y-20.
Although this drawing only has a fuselage without an engine, through the design of the wing and the layout of the line, he immediately discovered that this so-called Y-20S actually only has two engines! Then he was completely stunned.
What kind of magical improvement is this? With only two engines, it can definitely fly, but it is estimated that it can only take off empty…
The Y-20 is a transport plane, which has to carry dozens of tons of things! Does he think that Fatty is too big, or does he not know how to build an airplane at all? Hold on, hold on…
Dong Jun took a deep breath, suppressed his emotions that were about to explode at any time, and said in a deep voice: “Mr. Kang… your design is unreasonable, right?”
“Yun-20 is a transport plane. How can you fly with only two engines? Can you build an engine that is twice as powerful as the WS-20?”
Cai Yaobin and Pei Hengsheng, who couldn’t understand the drawings, were also stunned after hearing Dong Jun’s doubts, and then looked at Kang Chi with the same strange eyes as Dong Jun.
“Well, in fact, it’s more than twice. I plan to build a WS-30 with a thrust of 50 tons.”
50 tons of thrust? !
Hearing Kang Chi’s words, the people present were stunned again.
Seeing this, Kang Chi quickly added: “If you mind if I use your name, I can change it.”
“…”
Is this a question of name or not?
Dong Jun quickly thought about the possibility of a 50-ton thrust engine.
First of all, this thing is indeed promising.
As early as 1995, the GE90 produced by Tongyong Electric Aviation Engine Company had a thrust of 84,700 lbf (37.6 tons). Later derivative models were stronger than one another. In the ground bench test in 2001, the GE90-115B broke the Guinness World Record with a maximum thrust of 56.9 tons, becoming the world’s largest thrust aircraft engine.
Later, this big stick was taken over by GE9X, which has a thrust of 61 tons.
But the GE series of engines are tailor-made for large civil airliners after all, 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. For example, the inlet diameter of GE9X is as high as 4.5 meters, which is not conducive to maintaining the ground clearance of the engine and is easy to be involved in sand and gravel, so it is more picky about airports.
But do you think it is good? Of course it is!
No matter whether the 50-ton thrust engine proposed by Kang Chi can be used in military transport aircraft, and no matter what its fuel consumption and other performance are, as long as it can be developed, 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 aviation passenger aircraft have basically been 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…
But if we look back, according to statistics, China will need at least about 8,560 new passenger aircraft in the next 20 years.
Among them, there are 350 regional passenger aircraft, 6,470 narrow-body single-aisle mainline passenger aircraft, 1,550 wide-body passenger aircraft, and 190 cargo aircraft, with a total value of about 11 trillion yuan. If the after-sales service market such as maintenance and repair is added, at least another 5 trillion yuan will be added.
And this is just the Chinese market.
By monopolizing the global civil aircraft market, you can imagine how comfortable Boeing and Airbus are.
If we don’t take advantage of such a big piece of cake, thenYou can only watch others eat, or even be the one being 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. The first thing it built was the regional passenger aircraft ARJ21.
However, regional passenger aircraft carry fewer people, have a short range, are cheap per unit, and have a small market demand, so they are not profitable.
Then there was the C919. Although this passenger aircraft, which has obtained airworthiness certification from many countries, is known as a domestically produced large aircraft, it is actually just a narrow-body single-aisle trunk passenger aircraft.
The so-called trunk passenger aircraft is a medium- and short-distance route with a maximum passenger capacity of less than 200 people and a flight mileage of less than 6,000KM. In the field of civil aviation passenger aircraft, it is actually only a medium-sized passenger aircraft.
However, the demand for this type of 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 are large wide-body aircraft like A380, which have a maximum passenger capacity of more than 300 and can fly long distances across the ocean. This is also the top product of the aviation manufacturing industry.
Its demand seems to be small, with a quantity of only about 18%, but it can’t withstand the high unit price of one aircraft for two or three aircraft.
However, the research and development and manufacturing of such large wide-body aircraft is too difficult, even China is not so confident, so in the end, the old Russians with a relatively rich aviation technology background were pulled in, and the two sides worked together to develop CR929.
But the two sides bumped into each other for more than ten years, and finally parted ways unhappily. The CR929 project also became the C929 project, and the first flight date became an unknown.
So if Kangchi has already developed the T1200 super carbon fiber material and has developed a 50-ton thrust turbofan engine, then at least half of the problems of the C929 project alone will be solved.
But the question is, how can this thing be so easy to do?
The C929’s CJ-2000 engine has a design thrust of 35 tons, which has been a headache for COMAC for so many years. You’re going for 50 tons right away.
Isn’t this a big step? ”Mr. Kang, it’s not that I don’t trust you. Whether this engine is suitable for the Y-20 or not is not a big deal. After all, we are not afraid of trial and error in scientific research.” Dong Jun said helplessly, “But the problem is that you’ve taken such a big step. How long will it take to get it done? We haven’t even started working on the engine yet, and you’re asking us to build the fuselage. Aren’t you too impatient? Our production capacity is also limited…”
”Production capacity is not a problem.” Kang Chi retorted directly, “Mr. Cai is here. If you delay the delivery of the Y-20 because you help me build the Y-20S, Mr. Cai will definitely not blame you, right, Mr. Cai?”
”Ah? Um…right!”
”…”
”Also, I’m not taking advantage of you for free. I’ll pay you every penny for building the fuselage for me. As for how long it will take to build my engine…”
Kang Chi’s mind turned quickly and he said, “It will definitely be faster than you building the fuselage!”
As expected by Kang Chi, Dong Jun couldn’t help but retort after hearing what he said, “That’s impossible!”
”Don’t believe it? Then how about we have a competition to see who can build it first?”
”Let’s compete!”
Not bad, that’s the effect we want! Kang Chi was relieved when he saw Dong Jun had been tricked.
Once this guy was provoked, he wouldn’t be afraid that he would delay his plan by pretending to obey.
To be on the safe side, Kang Chi took the initiative to suggest: “Since it’s a competition, why not set up some small prizes… What do you want?”
”What do we want?”
Dong Jun hesitated for a moment, and finally mustered up the courage to say: “If you lose, just give us the drawings of the Silver Crane to learn from.”
Kang Chi smiled immediately.
Sure enough, although they seemed fine on the surface, they still had a knot in their hearts about the Y-20 drawings. When they found the opportunity, the first thing they thought of was to fight back to save face…
”No problem, but if you lose, you have to shout three sentences in front of everyone in your project department: Mr. Kang is awesome!”
As soon as this was said, everyone was immediately embarrassed.
This…
Is it so shameless? In fact, Kang Chi was also quite embarrassed, but he knew that for these researchers, nothing was more important than face, so compared to substantive rewards and punishments, things involving face were more lethal.
As long as he was not embarrassed, others would be embarrassed!
Sure enough, when Dong Jun imagined that scene, he got goose bumps all over his body.
”Can we… change it?”
”Give up so quickly?”
”No… I… We have no objection!”—— 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! If you don’t know, you would think you got the true teachings of Academician Zhang Dayuan.”
”Haha, this trick is indeed learned from Academician Zhang.”
Kang Chi then smiled and told Cai Yaobin about Zhang Dayuan’s crazy monster pulling operation when he was working on EUV light source. Cai Yaobin couldn’t help laughing and said: “This is really something he can do, full of Zhang flavor!”
However, after laughing, Cai Yaobin couldn’t help but worry and said: “No But are you sure you can really make it so quickly? ”
”Don’t underestimate Dong Jun and his team. If they can make a big Y-20 so quickly, they might be able to make it for you in one or two months…”
”After all, the production line of the Y-20 is ready. Even if you make a big change, it is based on the Y-20. Most of the things can be directly applied.”
”What? You don’t believe me either?”
”That’s not… It’s just that it feels a little unrealistic…”
”That’s why I don’t believe it.”
”…”
After Kang Chi left, Dong Jun and others immediately conducted a detailed analysis of the design plan given by Kang Chi.
After all, a large aircraft is not an ordinary equipment. It is a very systematic project. Any change will affect the whole body.
Although the Y-20S is only changed from four engines to two engines, it sounds like it only has two fewer engines. The appearance may look similar, but in fact there are many small changes involved.
Just now, Dong Jun and his team 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 began to be more and more shocked.
More than a dozen engineers in their project team gathered together to study for a long time, but they could not find any flaws in the drawing.
After carefully reading the drawing, Chi Jinliang could not help rubbing his slightly dry eyes and exclaimed: “Whether we can find the problem or not, it can be seen from this drawing that he has basically understood our Yun-20 drawings…”
”No wonder he didn’t ask anything when he visited the workshop just now.”
”That’s not a problem.” Dong Jun shook his head solemnly: “After all, he can build an EUV lithography machine. I never thought it was difficult for him to understand the drawings thoroughly.”
”But the problem is, learning and flexibly using them is a big deal. These are two completely different things. How could he understand the blueprint so quickly and complete the improved design? Is there really someone whose comprehension is so terrible…”
”Ah… I can only say that comparison is frustrating. Now everyone in the Chinese scientific research community doesn’t know this freak. This pervert seems to have no bottleneck in any field. And once he makes a move, the wisest decision for others is to run away… I heard that the camera lens manufacturers in Xiaobenzi are ready to completely withdraw from the Chinese digital camera market this year… If Daqin Optics could not enter the European M market, these companies would have to be skinned alive. ”
”Well, I’ve heard about this, too.” Dong Jun sighed, “Fortunately, this time he seems to be only responsible for the development of the engine, and the fuselage will be handed over to us, so even if he really makes it, we shouldn’t be as miserable as Harbin Aircraft…”
”Ahem… Mr. Dong, you’re not going to admit defeat, are you?”
”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 make a high-thrust engine.”
”But no matter how perverted he is, he can’t As for the speed of building the fuselage faster than us? Starting from today, half of the people in the project department will be transferred to help him build the fuselage. I don’t believe that this can lose! ”
After hearing this, Chi Jinliang was immediately surprised and said: “Half of the people? !”
”Yes, anyway, Cai Yaobin just expressed his position. It is none of our business to delay the delivery of the Y-20. I want to see whether this so-called Y-20S is worth delaying the delivery of the Y-20.”
”…”—— After leaving Xi’an Aircraft, Kang Chi and his team finally arrived at Harbin Aircraft Industry Group after more than 8 hours of flight.
It can only be said that the Y-12 has a cruising speed of 250Km/h.The speed is really slow, and it has to land once for refueling during the 2,000-kilometer flight. This makes Kang Chi more expectant of Yinhe getting the test flight permit.
The main reason for coming to Harbin Aircraft Industry Group this time is that Cai Yaobin helped China Aviation Industry Group to test Kang Chi’s attitude on the phone.
In fact, it is also very simple. It is a trend for electric rotorcraft to replace traditional helicopters. The two helicopter manufacturing bases of Harbin Aircraft Industry Group and Changhe Aircraft Industry Group seem a bit awkward. With such a large production base and so many mouths to feed, it would be best if they could not be shut down.
So the aviation industry wants Kang Chi to use the manufacturing technology and equipment of electric aircraft to invest in Harbin Aircraft Industry Group and Changhe Aircraft Industry Group, and turn them into Yinhe’s manufacturing bases.
In fact, Kang Chi had this idea before. After all, there are ready-made manufacturing bases 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 Kang Chi takes the initiative to propose it, it will have a negative impact, and people may think that he is embezzling state assets.
But when they take the initiative to propose it, the meaning will be different.
If Kang Chi does not provide technology, they will be eliminated by the times, so how can it be said that they are embezzling? And when they take the initiative to propose it, Kang Chi can also take more initiative, and have more say in the two companies in the future, avoiding some disobedient people from hindering his plan.
