Technological power starts with upgrading lenses.

Chapter 232: Change 20

This helicopter that has undergone explosive modifications has only completed the production of the main frame. Kangchi has not even installed the rotors.

Zhang Qing could tell it was an aircraft only because it had two slightly upturned wings. Otherwise, just from the shape of the fuselage, it would be easy for people to associate it with the front of a high-speed rail bullet train.

Zhang Qing circled around the helicopter with some novelty, and then asked curiously: "Why are you suddenly interested in helicopters?"

"I want to build a private car for Taiwan. Of course, if the military is interested, I can sell it to them."

"..."

Good guy, are you really starting to build arms?

However, Zhang Qing had actually expected that Kangchi would develop in this direction sooner or later. After all, after the chip and energy problems were solved, there were actually not many places in China where civilian technology, or economic development, was restricted.

At this time, maintaining a stable development environment becomes even more important.

This sodium battery theft case also fully demonstrates that those on the other side of the ocean have almost reached the point where they have trouble sleeping and eating...

After visiting Kangchi's new laboratory, Zhang Qing began to report the results of the sodium battery theft incident to Kangchi.

"... In short, Tesla has been taken back from the enemy this time, and may also face a fine of more than one billion yuan, most of which will be used to compensate for our losses, and the rest should be used to commend the departments that made the meritorious service this time. "

So at least in the Chinese market, they have to accept it even if they don’t accept it.

Although Tesla is likely to have a group of loyal consumers recharging their faith no matter how expensive it is, the number will definitely be much smaller than before.

"No, in addition, he expressed his hope to cooperate with Datang on battery-swapping models, and even implicitly expressed the idea of ​​promoting the battery-swapping model together in Europe..."

Of course, in order to deal with possible decoupling, China has actually made preparations in advance and proposed strategies such as dual circulation and internal circulation.

If all restrictions are imposed, it will be no different from complete decoupling of the economy.

If we follow that rule, we will have to restrict the export of all chips and electronic products produced in China.

Of course, China does not want this to happen, because we are actually having a lot of fun under the system led by old M, and it is actually beneficial to our development.

Did they forget that Datang Heavy Industries was on the selection list?

In fact, strictly speaking, all companies that want to cooperate with Datang Heavy Industry, including Tesla, have violated the original regulation that "companies that purchase products from Longteng Technology Group will also be subject to the same trade controls."

"Don't make me guess..."

But in fact, basically all the wafer factories in China ignored the ban and rushed to buy Qinguang No. 1, and the chips they produced were immediately turned into various electronic products.

Especially now that sodium batteries are available, CATL has joined the Longteng Technology camp with a huge battery industry chain, which means that in the future, China's entire automobile and battery industry chain will have a direct or indirect cooperative relationship with Longteng Technology.

Chips, electronics, plus cars, batteries.

"In addition, their Greater China head Anil expressed his apology and gratitude to me on the phone yesterday." Zhang Qing suddenly smiled and asked, "Do you know what his original words were?"

Promote battery swapping in Europe?

In Kangchi’s view, Tesla’s switch to battery swapping is only a matter of time.

"Haha... He is quite aware. He knows that he has actually gone through hell this time."

"Well, he said that he is actually the best scapegoat, but because he is in China, he is also the most difficult scapegoat to die. Thank you to China for monitoring him... and protecting him during this period."

With so many companies and products, it is simply impossible to limit them.

But Kangchi did not expect to take the initiative to propose the battery swap model to Europe.

Therefore, companies in China that have business dealings with Longteng Technology Group have basically not been affected.

The result is that there are two parallel systems in the world.

If they insist on integrating trams, it means they can only use expensive lithium batteries.

If we are really decoupled, because our industrial chain system is more complete and our educational, economic, technological and other foundations are not bad, we can actually be very happy playing under our own system.

Even the ability to win people's heads is not much better than the opponent's.

As for Lao M, it is actually just some people who want to decouple, because they can now easily buy products made in China by printing money.

But after decoupling, a large number of high-quality and low-priced things will no longer be available, the money printed will be even more watery, and the quality of life of ordinary people will drop significantly.

Their younger brothers are not very obedient and united because they know that life will be more difficult after decoupling.

This time Tesla China expressed its willingness to join the battery swap camp, which is actually a signal.

With Tesla taking the lead, can other joint venture car brands join the battery swap camp? Is it far away?

So just through this phenomenon, we can actually see that the selection list is slowly losing its deterrent effect...

"This time it seems to be a signal proactively released by the European Union. Tesla is just a transmitter." Zhang Qing explained with a smile, "They seem to be really serious about energy conservation and carbon reduction."

Kang Chi nodded: "They do care about environmental protection issues, but in essence, their energy issues are no less important than ours. Otherwise, why would they risk offending Big Brother and extend an olive branch to us..."

"Well...then what do you think about this?"

"Don't worry, the current production of sodium batteries is still limited, and it's not enough for your own use. The EU should wait until the domestic battery swap model is fully rolled out."

Kang Chi thought for a moment and then said, "I think the reconciliation with Tesla and subsequent cooperation are no problem."

“The original purpose of the country’s introduction of Tesla was to spur domestic new energy car companies. We cannot turn sodium batteries and battery swap modes into a greenhouse or protective umbrella for our own brands, otherwise they will soon lose their Entrepreneurship and competitiveness, in addition, Tesla’s localization rate is also quite high, and the real money it can make is not that much.”

Zhang Qing nodded, then suddenly took out a bottle of champagne and said with a smile: "After we have finished talking about the business, can we celebrate the smooth progress of the next power swap mode?"

Kang Chi couldn't help but be stunned when he saw the champagne, and then said with a smile: "Of course."

Using sodium batteries to create a battery swap model is, after all, a bet on the development of the entire group in the next five years at least. And this wave of catching so many electricity rats in one breath can be said to have shocked the entire country of China, and presumably there will never be another one in the future. No one dares to deliberately smear Datang Heavy Industries’ power swap model.

It is foreseeable that the power swap model will inevitably enter a period of rapid development.

Such a significant victory is indeed worthy of a ceremonial celebration.

Kang Chi took the champagne and opened the cork with a bang.

As the light golden wine sprayed out, a faint aroma of wine also spread.

Although there were only two people, the atmosphere was not very lively, but with the four white girls still working non-stop, the entire workshop was actually in a very noisy state. In such an environment, the two of them clinked glasses. The picture is quite atmospheric.

However, knowing that Kang Chi had something to do next, the two of them just took a small sip, just to express their feelings. After a simple celebration, Zhang Qing asked Kang Chi to continue busy with his work, while she quietly watched Kang Chi assemble the aircraft, enjoying this rare leisure.

During this period of time, she was really busy and a little dizzy. If the power swap mode could achieve such a major stage victory, the first person to breathe a sigh of relief was probably not Kang Chi but Zhang Qing.

So she looked at it and actually fell asleep leaning on the chair...

After discovering that she fell asleep while sitting down, Kang Chi couldn't help but feel a little guilty. He quickly put down his work and ran home to get a blanket to cover her.

Then, he went on to work on his aircraft.

Although Kang Chi asked for the Z-20 drawings from the military, he actually had no intention of replicating a Z-20 according to the drawings from the beginning.

The drawings are just for reference, and then based on this, drastic improvements will be made according to his ideas.

In fact, it's not called an improvement, it can only be called a variant. The real improvement will probably have to be upgraded.

There are two main aspects to the variations of Kangchi.

The first is the variant of the drive method.

With the 1200wh/kg energy density lithium battery and the 1500Ps horsepower 'Hongtu' electric motor, Kangchi can completely change the entire aircraft drive system to electric.

Structurally, electric helicopters can be made simpler and lighter than turboshaft helicopters that burn aviation kerosene.

At the same time, the electric motor is also quieter, which can improve driving comfort.

As for feasibility,

First of all, from the perspective of engine performance, the Z-20 helicopter is equipped with a domestic turboshaft 10 engine with a rated power of 1600KW and can reach 2000KW in emergency output conditions.

按照1Ps=0.735千瓦来算，涡轴10发动机换成马力就是2176Ps，极限状态下是2721Ps。

Although it seems to be much stronger than the 'Hongtu' motor.

However, the dead weight of the turboshaft 10 engine is as high as 220 kilograms. This weight can be equipped with three 'Hongtu' electric motors, with a total horsepower of up to 4500Ps.

In fact, even if you directly replace the straight 20-inch turboshaft 10 with a 'Hongtu', it will basically be fine to fly, but the speed will be slower.

Therefore, in terms of power, theoretically it is not a problem at all.

But Kangchi is not planning to build a single-rotor helicopter. He wants to build a dual-main motor helicopter.

This involves the second variant of Kangchi.

He chose a helicopter as his vehicle because of its vertical take-off and landing method, which makes it less dependent on the environment.

After all, Pangu Base has an airport, but his hometown, Datang Heavy Industry and other places do not have airports, so helicopters are more convenient transportation.

But the helicopter was too slow, so Kangchi wanted to imitate the old American V22-Osprey helicopter.

The V-22 is similar in appearance to a fixed-wing propeller aircraft, except that the two engines on the wingtips can rotate upward, so it has the same vertical take-off and landing capabilities as a helicopter.

After taking off, it can switch to fixed-wing mode. It has the advantages of fast speed, long range and low fuel consumption of fixed-wing propeller aircraft. Its maximum flight speed can reach 509KM, making it the fastest flying helicopter in the world.

The biggest problem with electric helicopters is actually battery life.

A full 20-meter fuel tank is about 2 tons. If it is directly replaced with the previous lithium battery with an energy density of only 200-300wh/kg, it will only produce 600 kilowatt-hours of electricity at most, and it is estimated that it will not even be able to fly for one hour.

But if you can switch to a fixed wing, both the range and flight time can be greatly improved.

At this time, adding a lithium battery with four or five times the energy density, it should not be a problem to fly 20 kilometers like the Z-800.

And the most important thing is that because of the structure of the electric helicopter, this electric helicopter will be much cheaper than the Z-20 in terms of both construction and use costs.

The bare metal cost of a Z-20 without any weapons and equipment is about 1 million, and with the same money, five electric helicopters with similar performance can be built.

Although Kang Chi had only completed manufacturing the main frame when Zhang Qing came, this was the largest workload and the most difficult.

As for the installation of the rotor and shell, it is the simplest.

[Item: Electric tilt-rotor aircraft]

[Manufacturer: Kangchi]

[Item Level: 1]

[Experience: 0/100000]

[Analysis items: no analysis items]

[General experience: 493464]

[Mastery Points: 56 (+19)]

As White Girl No. 3 finished installing the last shell, a faint light that only Kang Chi could see flashed immediately, and the system panel popped out.

Damn it, it was a one-time success?

This was far beyond Kang Chi's expectation. He had originally thought that he would have to test it at least a few times and solve potential problems before the system panel could pop up.

But then he thought about it and realized that he had gained a lot of experience in equipment manufacturing by analyzing various items. Both his design and manufacturing capabilities had been greatly improved without even realizing it.

Is it harder to modify a Z-20 than to build a photolithography machine?

Thinking of this, Kang Chi couldn't help but feel a little proud, looking at the electric version of V-20 he had built using Zhi-22's technology with a look of satisfaction on his face.

At this moment, Zhang Qing suddenly woke up.

And her first reaction when she woke up was to look at her watch.

Ah, it's already four o'clock?

That’s it, there’s still a meeting at 4:30!

And when he raised his head and looked around, he was immediately surprised by the assembled helicopter in front of him.

"This... you built this helicopter while I was sleeping?!"

"It was almost done when you came here." Kang Chi smiled, "And do you know that in such a noisy environment, you slept for more than three hours in one breath while leaning on the sofa..."
