readx;?“ Thank you, Mr. Scott, "Although I don't know how much this invitation is worth, since this Scott is a senior member of EAA, I think this invitation can still be worth a few dollars, Lin Zheng first politely thanked Scott, and then asked Scott curiously: "Mr. Scott, can you tell me more about this EAA and EAA aerial expedition?" Frankly speaking, my main business is electronics, and I don't know much about aviation aircraft. Pen ~ Fun ~ Pavilion www.biquge.info+"

"Of course, it's my honor," Scott also smiled when he heard Lin Zheng's words, he was not annoyed that Lin Zheng didn't know the famous EAA, but appreciated Lin Zheng's honesty: "For many people, EAA is a carnival of opportunities for aviation enthusiasts, and it is also the best opportunity for aviation enthusiasts around the world to learn about the latest civil aviation technology development and future development trends...... I'm talking about civil aviation, which is really about people, not big Boeing and Airbus aircraft...... Here you can see the best performances, as long as you are good enough to attract investors to support you......"

"This one doesn't need to," Alex said. Durand boldly said Scott: "Mr. Lin is a monopoly himself. ”

"Oh......" Scott smiled embarrassedly, and he immediately avoided the topic knowing the hint in his boss's words, "In short, if you want to promote your new energy power system around the world as soon as possible, come to EAA." ”

Although there are still doubts about Scott's words, and I doubt whether this so-called EAA aerial expedition is really so powerful (mainly because the data of only 110 million US dollars in a week has left a very bad impression on Boss Lin), but Lin Zheng is really moved in his heart, not to mention that Americans like to exaggerate when talking, but this does seem to be a good platform?

Lin Zheng hesitated here, Alex. Durand couldn't help it. Interrupting Lin Zheng's thoughts, he asked eagerly, "Mr. Lin, I want to ask you a question." ”

"You say."

"Do you have any promotional materials for this autogyro you just mentioned?"

"Of course there is," Lin Zheng patted his head with sudden realization, a little annoyed: Look at my brain! "Wait, pony, go." Bring us the information on our autogyroplane. ”

Although it is a domestic air show, but to exhibit, visit the old and young, Lianchuang Technology carefully prepared promotional materials, each promotional material is not only beautifully printed, but also written in Chinese, English and French Chinese, with these three languages, basically do not have to worry about the other party can not understand what is said above.

The overall shape of this autogyro from Lianchuang Technology did not surprise Alex. Durand's expectation is that as a new company that has just stepped into this industry, or even has not yet set foot in this industry, they can't and dare not adopt such a radical form design. The overall design style is quite conservative, which is the most traditional autogyro shape. But Alex. Durand still praised some of the innovative designs of Lianchuang Technology, such as the design that cleverly combines the cooling system of the battery and motor with the cabin insulation system. Durand David exclaimed: "**, this is a genius design!" ”

This kind of small aircraft, usually there is no insulation design, spring, summer and autumn are good to fly the plane, winter to drive this kind of cheap small plane is simply a crime, but the ingenious combination of Lianchuang Technology, the use of the engine's own cooling system to provide heat for the cabin, although it is not sure how high the thermal efficiency can be. But it's not a bad thing, is it?

He became more and more interested in Lianchuang Technology, and his eyes became brighter and brighter. shouted at Lin Zheng: "Lin, I still underestimated your strength, I think." We may be able to work together on a broader scale. ”

Lin Zheng was just about to answer, when Scott's voice came from Lin Zheng's left: "Mr. Lin." What is this thing? ”

Looking in the direction where Scott's voice came from, Scott was standing in front of a mechanical product that looked very strange and seemed to look like some kind of cutting display, and was curiously asking Lin Zheng at this moment: "I look like some kind of power equipment." But why is there no power take-off? ”

"That?" Looking at the thing Scott was looking at, Lin Zheng smiled: "Oh, that's our latest flywheel battery." ”

"Flywheel batteries?" Scott blinked, a little puzzled: "You said this thing, right...... Battery? ”

"That's right, it's a battery." Lin Zheng nodded affirmatively.

"But ......" pointed to the cutting model of the "flywheel battery" in front of him, Scott was a little dumbfounded: the battery himself is not unseen, and even the tens of thousands of dollars of black box batteries dedicated to the plane are not uncommon, but this thing in front of him is completely different from all the batteries he has seen, if it weren't for Lin Zheng saying that this product is a battery, no one can associate this thing with the word battery, just like Scott said, this thing looks like some kind of power equipment.

"Flywheel batteries?" Alex. Durand was also confused: What the hell is this?

"The flywheel battery is a new generation of energy storage technology developed by our company, this new battery sweeps away the current battery to energy storage in a tiger chemical way, and uses physical energy storage, so to speak, at the current level of technology, about every 6.5 to 7 kilograms of lithium-ion batteries can store 1 kilowatt-hour of electricity, but the specific power of the flywheel battery we developed has reached 3 kilowatt-hours of energy per kilogram, which is nearly 30 times higher than the traditional lithium-ion battery."

Speaking of this flywheel battery, Lin Zheng is a handful of snot and tears, from the original and the Capital Battery Research Institute together with the joint research and development of this flywheel battery to now, it has been a full 7 years, the average annual investment in it is not less than 10 million US dollars, in recent years, with the acceleration of research and development progress, the annual investment required is more than 100 million US dollars, so long, although a lot of technical progress has been made, but now it can only be produced in small quantities in the laboratory, There is still a considerable distance to go before large-scale commercial production.

Why does Lin Zheng earn a lot of money every year, but he doesn't have much spare money in his hands? The reason is simple. There are so many gold-swallowing monsters in his hand, and no amount of money can stand up to spending it, as for why use dollars to calculate it, because in the early research and development process, many raw materials and research equipment were not available in China, and all of them needed to be ordered from abroad, and foreigners were to buy things. That must require dollars.

But Alex. Durand didn't know this, hearing the number 30 times, his eyes suddenly lit up and frightened, swallowed two mouthfuls of saliva hard, and asked eagerly: "How powerful is this thing?" You should have the information, right? Can I see if it's okay? ”

Of course, there is nothing that can't be done, since the flywheel battery was specially brought to the exhibition, Lin Zheng originally had some kind of bad little abacus, and a large number of promotional materials were of course essential.

Alex after reading the promotional materials. Durand, who burst into a foul language to express his inner feelings: "Whata**! ”

It was solid and frightened by the information on the propaganda materials: in the civilian sphere. Lithium-ion is already the most advanced large-capacity battery today, and the 18650 class battery just made by the Japanese can reach the level of /kg. This is already the highest energy density of today's batteries, but now, the Chinese have actually come up with a battery of /kg?

Nima, can everyone still have fun together?

More so Alex. Durand is shocked that the power density of this flywheel battery can reach an astonishing /kg, that is, one kilogram of this battery can store 20 kilowatt-hours of electricity.

But as a special pilot, Scott considered the problem from a completely different angle, he was more concerned about the technical aspects, and asked Lin Zheng with a look of surprise: "Then can you think so?" With a brand new battery like yours, like this 172R, the battery itself weighs only one-thirtieth of a traditional battery? ”

If that's the case. Wouldn't it mean that the range of this 172R could reach 15,000 kilometers by replacing it with this flywheel battery?

15000 km?!

As soon as this number came out, Scott was firmly frightened by himself: this flight distance was even longer than the range of the Boeing 747-400!

Of course. No one would be so extravagant to be equipped with so many batteries, Lin Zheng said just now. This battery reaches a high price, but in any case, after the application of this brand new battery. The electric 172R has no problem surpassing the traditional fuel-powered 172R in terms of range, and can even achieve a smaller dead weight of the aircraft.

With a wry smile, Lin Zheng said: "That's right, but the problem now is that the cost of this battery is too high." ”

"How tall?" After a moment's hesitation, Scott cautiously asked, "Oh, if this is your company's secret, I can fully understand it." ”

"There's nothing that can't be said about that, it's about $12,000 per kilowatt hour of electricity...... This is already the best level in the world. ”

“……”

Alex. Durand and Scott were speechless: Sure enough, it's high enough!

The cost of the most advanced lithium-ion battery in the civilian grade is only about 900 per kilowatt hour, and this product costs 12,000 US dollars per kilowatt hour? Who can afford this thing Nima?!

Scott was a little disappointed, but Alex. After being speechless for a short time, Durand immediately showed the true character of a profiteer: "Mr. Lin, what level do you think the cost of this battery can reach in the future?" ”

Considering the huge advantages of this physical energy storage battery over traditional chemical energy storage batteries, Alex. Durand believes that even twice the price of this thing is acceptable than that of traditional chemical batteries, and the only question is whether it can be done.

"Future ......" pondered for a while, Lin Zheng said: "If there is 20 years, I think it can be reduced to about $2,000 per kilowatt hour." ”

"Great!" Alex. Durand slapped his face excitedly: "If so, Cessna hopes to be able to cooperate with you on this project." ”

Alex. Durand's sudden proposal to cooperate on physical batteries was somewhat unexpected by Lin Zheng, but it makes sense to think about it: if the price of flywheel batteries drops significantly in the future, Cessna will have a reliable base in the field of new energy, which is too important for an aircraft company.

But Lin Zheng's reaction made Alex. Durand was stunned......

"Cooperation? We need to think about this carefully, maybe you may be a little misunderstood, but we are not short of money now......" Lin Zheng's answer was direct enough: You Cessna think that we are exhibiting this flywheel battery at this year's Zhuhai & Hainan Air Show to make money? Sorry, you thought wrong.

Alex. Durand really thinks so, in his opinion, Lianchuang Technology must have encountered a problem in terms of funds when it took out the flywheel battery, a revolutionary energy storage product, at this time, and hoped to find an opportunity to raise funds at this air show, but now Lin Zheng actually told him that you think too much.

"But it's not like we're completely without a basis for cooperation." Just in the heart of the anxious Alex. When Durand was thinking about how to convince Lin Zheng, Lin Zheng's tone actually changed.

"......" Alex. Durand blinked his eyes twice, and looked at Lin Zheng with a confused expression, he was completely stunned by Lin Zheng: One moment you said no, and the next moment you said that there is no basis for cooperation, what are you doing?

"Simply put, what is there about Cessna that we should work with?" With his hands spread, Lin Zheng asked Alex. Durand asked rhetorically.

Alex. Durand suddenly realized!

That's right, cooperation also depends on people, especially this revolutionary new technology, in the case of the developer is not short of money, the choice of cooperation object is worth considering, money is not the most important thing to consider, the most important thing to consider is that the partner is able to help themselves quickly promote this product and make more money.

Does Cessna have the strengths? Frankly, it doesn't seem to be enough.

Although the status in the field of business jets and small aircraft is very high, but to put it bluntly, in the field of aviation, a number of small aircraft manufacturing companies led by Cessna, Gulfstream, etc., are just picking up the leftovers of the two behemoths of Boeing and Airbus......
