"In the field of aircraft carriers, we in the East can be regarded as the standard setters. Now, aircraft carriers from various countries are benchmarking against ours." Qin Tao looked at the relevant information with a smile on his face.

The French aircraft carrier seems to have no new design. It is a complete replica of its own aircraft carrier. Except for the catapult, everything else is almost copied, especially the island. It is a complete replica of our own aircraft carrier.

.

"Yes, our technology is the most advanced. Of course they have to benchmark our technology." Xu Zhengyang said: "However, because their electromagnetic catapult is not up to standard, it is not easy to implement these plans."

"Yeah, why doesn't anyone come directly to buy our catapult?" Qin Tao shook his head, looking helpless.

"Because we can't sell it even if they know it," Xu Zhengyang said.

"Electromagnetic catapults cannot be sold. We also have steam catapults, which are guaranteed to be cheaper than American ones."

When we were developing catapults, we followed two routes. The electromagnetic catapult was a late strike, and finally won the recognition of naval leaders with its advanced performance. The Eastern Navy bypassed the steam catapult and directly entered the electromagnetic catapult era.

However, after all, the steam catapult has been built and tested. It is considered mature and can be sold to make money. There is no need to keep this thing secret.

Xu Zhengyang smiled. Just when he was about to continue talking, his cell phone rang. He opened it and took a look, then reported to the official work.

"Mr. Qin, there is an engineer working on ground equipment who wants to see you."

Ground equipment? Qin Tao was a little curious: "We are engaged in maritime equipment, and it has nothing to do with ground equipment. Why did he come to me?"

"He said there are some design ideas for ground main battle equipment that he wants to discuss with you."

When did I become an expert in ground combat equipment? Qin Tao smiled: "I don't have the ability, please ask him to go back."

"oh."

"By the way, what's his name?"

"Mao Min, Mr. Mao."

Qin Tao suddenly became excited: "Okay, invite him in!"

Xu Zhengyang was a little curious. Didn't Mr. Qin's attitude change too quickly? He said he didn't see him at first, but then he saw him as soon as he heard his name?

Of course Qin Tao had to meet him. He knew this person, the famous designer of main battle equipment!

Everyone knows that the most advanced tank in the East is the Type 99, and the designer of this tank is Mr. Zhu. However, Mr. Zhu only built the prototype of the 99 tank and then retired.

Later on, other people took over the redesign, and Mr. Mao, who was born in the 1960s, bravely shouldered the heavy responsibility and instigated the advanced three-phase modification.

The early 99 tank still had many flaws. For example, the engine only had 1,200 horsepower, the transmission system still had planetary gears, and the fire control system was not advanced enough. These were the focus of later improvements. The engine was increased to 1,500 horsepower, and even later

1800 horsepower version, hydraulic transmission, hunter-killer fire control, etc.

In the later modifications of the 99 tank, the combat effectiveness has undergone radical changes, which is enough to become a world-class level. This is also inseparable from the contribution of Chairman Mao.

If this person comes to see me, he must have something important to do, so he needs to meet him!

Soon, Mr. Mao with white hair walked in. When he saw his hair, Qin Tao was startled. Mr. Mao was born in 1962 and is only in his forties now. He actually has a head full of white.

It’s all because of busy work!

This is a person who has devoted his whole life to the development of the country's military industry! Qin Tao has always respected such people very much.

"Mr. Mao! Come, please sit down. If you come to me, if you need any help, just ask."

Mr. Mao nodded: "I know your time is valuable, so I won't waste your time. I'll just say it directly. Mr. Qin, we are currently preparing for the third phase of the tank improvement project. One of our groups is demonstrating the possibility of electric tanks.

."

Electric tank? Qin Tao was speechless for a moment. Lao Mao, let’s just play with electric cars. Electric tank? Do you plan to make the tank explode more violently?

Qin Tao was about to shake his head immediately, but he still felt that he should listen to what the other party said.

"Electric motors have many characteristics, such as high torque. If we create an electric tank, it means that the tank's acceleration will be very good, which is very useful for avoiding flying artillery shells."

Qin Tao nodded, that's really what happened. In the era of internal combustion locomotives, it was difficult to build an electric car that could hit 100 mph in five seconds. But in the era of electric vehicles, a large number of trams could claim to hit 100 mph in five seconds. The electric motor relied on

High torque makes this possible easily.

"The electric motor has very few parts, making it easier to maintain."

Qin Tao could only continue to nod. Yes, in the era of oil vehicles, routine maintenance was required every half a year or a year, such as replacing the third filter and so on. However, electric vehicles did not need it. Electric vehicles did not require any maintenance. At most, they only needed to upgrade the system.

"It is impossible to make fuel for the military station, but it is easy to make electricity..."

"It is easier to realize automatic control of electric motors to prepare for future unmanned tanks..."

President Mao mentioned a lot of advantages. If he mentioned one, Qin Tao would nod in agreement with one. Yes, these are indeed advantages and must be approved.

"President Qin, so we are demonstrating the issue of electrification of land-based main battle equipment."

Qin Tao nodded: "Yes, these are all advantages you mentioned, but electric drive not only has advantages, but also has many disadvantages. First of all, the first and biggest disadvantage is where the electricity comes from. Our electric vehicles use

It’s an 18650 battery. Don’t you have the same idea? The island country uses this AIP system to build submarines. You should also know the results, right?”

Even if it is an electric car, carrying so many batteries is a burden, so Golden Sun Company is studying a wireless power supply solution, which is also considered the best solution.

This chapter is not over yet, please click on the next page to continue reading! "Yes, so we want to come to Mr. Qin and ask you to provide us with some opinions. We have gone to Golden Sun Company, but they can't tell us clearly."

Golden Sun Company is engaged in electric motors. They only make trams on a casual basis. They have no technical roadmap. They build whatever Qin Tao tells them to build. It's as simple as that.

Therefore, now we can only come to Qin Tao.

Qin Tao rolled his eyes: "Have you ever considered nuclear power?"

"Yes, I have considered that if the tank is equipped with nuclear power, it will have unlimited endurance. However, once it is hit on the battlefield, it will be very scary. Our national defense policy is still defensive in nature, so this is unreliable.

." President Mao nodded. They had studied it carefully and concluded that it was inappropriate.

The American soldiers only used some depleted uranium bombs, which caused a lot of problems. If they installed nuclear reactors on these tanks, once they were exploded on the battlefield, the consequences would be disastrous.

Unless it is a nuclear fusion reactor, but this is still far away.

"Wireless power supply is even more inappropriate."

"Yes, it is impossible to bury power supply coils on the battlefield."

"So, there is only one way."

"any solution?"

"Use the internal combustion engine to generate electricity, and then use the electric motor to drive the tank."

When he heard this sentence, Xu Zhengyang suddenly wanted to laugh. This was like farting and taking off his pants! Using oil to generate electricity, and then using electricity to drive the tank, what is this picture?

There are many similar systems on warships. This is called a ship-wide integrated power system. This is done because more and more power-consuming equipment is used on warships, and a suitable power distribution plan is required.

What about tanks?

Unless future tanks use electromagnetic guns, the engine is mainly used to drive the tank forward and does not require much power supply at all!

"Mr. Qin, some large vehicles, such as mining trucks, will adopt this solution, mainly because the power is too strong and the transmission device is inconvenient to design. Our tanks have a complete transmission system, and we have developed a mature hydraulic system.

I’m afraid there’s no need to use this method for the transmission system, right?”

Electric transmissions are used in large mining vehicles for convenience. After all, it is simply impossible to use mechanical shifting on a vehicle with one wheel that is taller than a person.

If we want to talk about using it in military vehicles, we have to mention Germany during World War II. Dr. Porsche at that time liked to play with electric transmissions and even built a batch of chassis. It was said that they could not run in a straight line...

"Oh, I didn't make it clear just now. It's not just an internal combustion engine and a generator, it's also an electric motor. You also need a battery."

Mr. Mao opened his eyes wide. Mr. Qin, we use electric drive. One of its great features is its simple structure. What are you doing? Making simple things complicated? Isn't this inappropriate?

"The biggest feature of this is fuel saving." Qin Tao introduced: "The internal combustion engine has various output curves. We can make the internal combustion engine work in the optimal provincial range and avoid repeatedly adjusting the throttle. For vehicles with this structure, the engine will either not start or not start.

To start, work at a fixed speed.”

"Mr. Qin, isn't this appropriate?" Mr. Mao frowned.

After studying vehicles for half a lifetime, Mr. Mao certainly knows that a car engine needs to change its speed all the time to obtain different output power to adapt to different situations, such as uphill and downhill, high speed and low speed, etc.

In this way, the engine's working range changes all the time, and the fuel consumption will naturally be very high. After all, the engine only has a very narrow range that is the most fuel-efficient.

The problem is, there is no way to solve it.

If the engine is turned up, the car cannot be used. If the engine is turned down, the car is not used enough. How can this kind of vehicle be used?

"There is a battery." Qin Tao said: "The battery is used as a buffer and compensation for power. For example, if the car is moving at a low speed and the power cannot be used, then the excess energy is stored in the battery. When the car needs to speed up or go to high speed,

When moving forward, more power is needed, so the battery outputs electricity to allow the motor to output more power."

"Mr. Qin, do you mean hybrid power?"

In addition to pure oil and pure electric vehicles, there are also hybrid vehicles!

There are two types of hybrids. One is plug-in hybrid. The battery of this kind of car is relatively large and can be plugged into a charging station for charging. It can travel dozens or even hundreds of kilometers on pure electric power. It does not use any oil at all in urban areas. It requires

Oil is only used at high speeds.

The other is the gasoline-electric hybrid. This method has a relatively small battery and does not require a charging station. It is completely charged by its own engine. It sounds like farting and taking off your pants. In fact, it can also save fuel.

When a car starts, it consumes the most fuel, so we use electric power! When the car stops and goes, and when waiting for traffic lights, it wastes the most, so let’s use electric power! At low speeds, electric power is enough, and at high speeds, we use gas. When the battery runs out, we use gas again.

Charge!

Of course, there is also a range extender, which is purely a generator and does not participate in driving the vehicle. It is to avoid the embarrassment of the car without a charging station and solve range anxiety. There is nothing remarkable about the technology and it is not part of Qin Tao's research.

within the range.

As for which one is better, a plug-in hybrid or a gasoline-powered hybrid, it all depends on the usage requirements. If you often travel in urban areas, it must be a plug-in hybrid. After all, you don’t need gasoline at all. You can charge it when it runs out. But if you run on the highway and the battery runs out, you can only use gasoline.
