Chapter 232: Modified Z-20
Chapter 232: Modified Z-20
This modified helicopter has only completed the main frame, and Kang Chi has not even installed the rotor.
Zhang Qing can tell that it is an aircraft because it has two slightly upturned wings. Otherwise, just from the shape of the fuselage, it is easy 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. Of course, if the military is interested, I can sell it to them.”
”…”
Good guy, it really started to make arms? However, Zhang Qing actually expected that Kang Chi would develop in this direction sooner or later. After all, with the solution of chip and energy problems, there are actually not many places in China where civilian technology, or economic development, is restricted.
At this time, maintaining a stable development environment is even more important.
This sodium battery theft case also fully demonstrates that those people on the other side of the ocean have almost reached the point of being unable to sleep or eat…
After visiting Kang Chi’s new laboratory, Zhang Qing began to report the results of this sodium battery theft to Kang Chi.
“…In short, Tesla has been taken advantage of this time, and may face a fine of more than 1 billion yuan. Most of the fine will be used to compensate for our losses, and the rest should be used to commend the departments that have made contributions this time.”
”In addition, Anil, the head of their Greater China region, called me yesterday and expressed his apologies and gratitude.” Zhang Qing suddenly asked with a smile, “Do you know what he said exactly?”
”Don’t make me guess…”
”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. Thanks to China for monitoring him during this period… and protecting him.”
”Haha… He is quite conscious and knows that he has actually been through hell this time.”
”That’s right. In addition, he expressed his hope to cooperate with Datang on battery swap models, and even implicitly expressed the idea of promoting the battery swap model in Europe together…”
Promoting battery swap in Europe? Tesla’s switch to the battery swap model is actually only a matter of time in Kang Chi’s view.
If they insist on the integration of electric vehicles, it means that they can only use expensive lithium batteries.
Although Tesla is expensive, it is estimated that there are a group of loyal consumers who recharge their faith, but the number will definitely be much smaller than before.
So at least in the Chinese market, they have to accept it.
But Kang Chi did not expect that he would take the initiative to propose to promote the battery replacement model to Europe.
Have they forgotten that Datang Heavy Industry is on the selection list? In fact, strictly speaking, including Tesla, all companies that want to cooperate with Datang Heavy Industry have violated the original regulation that “companies that purchase products from Longteng Technology Group will also be subject to the same trade control.”
But in fact, almost all wafer factories in China ignored the ban and rushed to buy Qin Guang No. 1, and the chips they made immediately became various electronic products.
If that regulation is followed, the export of all chips and electronic products produced in China must be restricted.
With so many companies and products, it is impossible to restrict them at all.
Therefore, in China, the enterprises that have business dealings with Longteng Technology Group have basically not been affected.
Especially now that there are sodium batteries, 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 direct or indirect cooperation with Longteng Technology.
Chips, electronic products, plus automobiles and batteries.
If all are restricted, it will be no different from a complete economic decoupling.
The result is that two parallel systems will appear in the world.
China certainly does not want such a situation to happen, because we are actually having fun under the system led by Old M, which is actually beneficial to our development.
Of course, in order to cope with possible decoupling, China has actually made preparations in advance and proposed strategies such as dual circulation and internal circulation.
If decoupling really happens, because our industrial chain system is more complete, and the foundations of education, economy, science and technology are not bad, playing under our own system can actually be very happy.
Even his ability to recruit people is not much worse than the other side.As for Lao M, in fact, only some people 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 goods will not be available, the printed money will be more watered down, and the quality of life of ordinary people will decline significantly.
Their younger brothers know that their lives will be more difficult after decoupling, so they are not very obedient and united.
This time, Tesla China expressed its willingness to join the battery swap camp, which is actually a signal.
With Tesla taking the lead, how long will it take for other joint venture car brands to join the battery swap camp? So just from this phenomenon, we can actually see that the selection list is slowly losing its deterrent power…
”This time it seems that the EU has actively released a signal, and Tesla is just a mouthpiece.” Zhang Qing explained with a smile, “They seem to be really concerned about energy conservation and carbon reduction.”
Kang Chi nodded: “They are indeed concerned about environmental protection issues, but in essence, their energy problems are no less than ours, otherwise why would they risk offending Big Brother and extend an olive branch to us…”
”Well…what do you think about this?”
”No hurry, the current sodium battery production is still limited, and it is not enough for our own use. The EU should wait until the domestic battery replacement model is fully rolled out before talking about it.”
Kang Chi pondered for a moment and said, “I think there is no problem with the settlement with Tesla and the subsequent cooperation.”
“The original purpose of the country bringing in Tesla was to whip up domestic new energy vehicle companies. We can’t turn sodium batteries and battery swapping into a greenhouse or umbrella for independent brands, otherwise they will soon lose their enterprising spirit and competitiveness. In addition, Tesla’s localization rate is also quite high, and the money that can really be earned is not much.”
Zhang Qing nodded, then suddenly took out a bottle of champagne and said with a smile: “After talking about business, can we celebrate the smooth sailing of the battery swapping model in the future?”
Kang Chi was stunned when he saw the champagne, and then smiled and said: “Of course.”
Using sodium batteries to create a battery swapping model is, after all, a bet on the development of the entire group for at least the next five years. This wave of catching so many electric rats in one go can be said to have shocked the entire China. I believe that no one will dare to deliberately discredit Datang Heavy Industry’s battery swapping model in the future.
It can be predicted that the battery swapping model will inevitably enter a period of rapid development in the future.
Such a major victory is indeed worth celebrating with a sense of ceremony.
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 and the atmosphere was not very warm, the four white girls were still working non-stop, and the whole workshop was actually very noisy. In such an environment, the scene of the two people gently clinking glasses was quite atmospheric.
However, because they knew that Kang Chi would still have things to do next, they just took a small sip and said it was enough. After a simple celebration, Zhang Qing let Kang Chi continue his work, and she quietly watched Kang Chi assemble the aircraft, enjoying this rare leisure.
She was indeed a little dizzy during this period. If the battery swap model can achieve such a significant staged victory, it is estimated that it is not Kang Chi but Zhang Qing who will be the first to breathe a sigh of relief.
So she actually fell asleep while leaning on the chair…
After finding out that she actually fell asleep while sitting, Kang Chi felt guilty. He quickly put down his work and ran back home to get a blanket to cover her. Then, he continued to work on his aircraft.
Although Kang Chi asked the military for the blueprints of the Z-20, he actually had no intention of replicating a Z-20 according to the blueprints from the beginning.
He asked for the blueprints just for reference, and then made drastic improvements based on them according to his ideas.
In fact, it is not called improvement, but only variant. The real improvement is probably still up to upgrading.
Kang Chi’s variants are mainly in two aspects.
The first is the variant of the drive mode.
With a lithium battery with an energy density of 1200wh/kg and a 1500Ps horsepower “Hongtu” motor, Kang Chi can completely change the drive system of the entire aircraft to electric.
The structure of an electric helicopter can be made simpler than that of a turboshaft helicopter that burns aviation kerosene.Lightweight.
At the same time, the electric motor is also quieter, which can improve the ride comfort.
As for feasibility, First of all, from the performance of the engine, the Z-20 helicopter is equipped with the domestically produced turboshaft 10 engine, which has a rated power of 1600KW and can reach 2000KW in emergency output.
According to 1Ps=0.735 kilowatts, the turboshaft 10 engine is converted into horsepower of 2176Ps, and 2721Ps in the extreme state.
Although it seems to be much stronger than the “Hongtu” motor.
However, the turboshaft 10 engine weighs as much as 220 kilograms, which can be equipped with three “Hongtu” motors, with a total horsepower of up to 4500Ps.
In fact, even if the turboshaft 10 of the Z-20 is directly replaced with the “Hongtu”, it is basically no problem to fly, but the speed is slower.
Therefore, in terms of power, it is not a problem at all in theory.
But Kang Chi was not going to build a single-rotor helicopter, he wanted to build one with dual main motors.
This involves Kang Chi’s second variant.
He chose a helicopter as his vehicle, first of all because of its vertical take-off and landing method, which is less dependent on the environment. After all, there is an airport at Pangu Base, but there are no airports in his hometown, Datang Heavy Industry and other places, so helicopters are more convenient as a means of transportation.
But helicopters are too slow, so Kang Chi wants to imitate the American V22-Osprey helicopter.
The V-22 is similar to a fixed-wing propeller aircraft in appearance, except that the two engines on the wingtips can rotate upwards, so it has the same vertical take-off and landing function as a helicopter. After taking off, it can be switched to a fixed-wing state, which 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 helicopter in the world.
The biggest problem with electric helicopters is actually endurance.
The fuel tank of the Z-20 is about 2 tons. If it is directly replaced with the previous lithium battery with an energy density of only 200-300wh/kg, it can only hold 600 kWh of electricity at most, and it is estimated that it can’t even fly for an hour.
However, if it can be switched to a fixed-wing, both the range and the flight time can be greatly improved. At this time, adding a lithium battery with four or five times the energy density, it should be no problem to fly 800 kilometers like the Z-20.
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 cost and use cost.
The bare machine cost of a Z-20 without any weapons and equipment is about 100 million yuan, and with the same money, 5 electric helicopters with similar performance can be built.
Although Kang Chi only completed the manufacture of the main frame when Zhang Qing came, this was the most labor-intensive and difficult part.
As for the installation of rotors and shells, it is the simplest.

As No. 3 Bai Niu installed the last piece of the outer shell, a faint light that only Kang Chi could see flashed immediately, and the system panel popped up immediately.
Fuck, it was successful in one go? This was beyond Kang Chi’s expectation. He originally thought that he had to test it several times at least and solve the potential problems before the system panel could pop up.
However, he thought about it again. By analyzing various items, he had already learned a lot of equipment manufacturing experience. Both his design and manufacturing capabilities had been greatly improved without him 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. He looked at the electric version of V-22 he had built with the technology of the Z-20 with a satisfied look on his face.
At this moment, Zhang Qing also woke up suddenly.
And her first reaction after waking up was to look at her watch first.
Ah, it’s already four o’clock? It’s over. There’s still another one at half past four.Meeting! When he looked up and looked around, he was immediately shocked by the assembled helicopter in front of him.
”This… you built this helicopter in the time it took me to sleep?!”
”It was almost finished when you came.” Kang Chi smiled, “And do you know that you slept for more than three hours in such a noisy environment while leaning on the sofa…”
