Warship of Great Power

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

The French aircraft carrier looks like it has no new design. It is a complete copy of their own aircraft carrier. Except for the catapult, everything else is almost completely copied, especially the island, which is a complete replica of their own island.

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

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

"Because they know that we can't sell it." Xu Zhengyang said.

"The electromagnetic catapult cannot be sold. We still have the steam catapult, which is guaranteed to be cheaper than the American one."

When the catapult was being developed, two routes were taken. The electromagnetic catapult was the last resort and eventually won the recognition of the naval leaders with its advanced performance. The Eastern Navy bypassed the steam catapult and directly entered the era of the electromagnetic catapult.

However, the steam catapult was built and tested after all, and it was mature. It can be sold to make money, and this thing does not need to be kept secret.

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

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

Ground equipment? Qin Tao was a little curious: "We are engaged in marine equipment, which has nothing to do with ground equipment. What does he want to see me for?"

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

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

"Oh."

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

"Mao Min, Mr. Mao."

Qin Tao was immediately excited: "Okay, ask him to come in!"

Xu Zhengyang was a little curious. Mr. Qin's attitude changed too quickly, right? He said he didn't want to meet him at first, but he met 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 Type 99 tank and then retired.

For the later modification, other people took over, and Mr. Mao, who was born in the 1960s, took on the heavy responsibility and tinkered with the advanced third-stage modification.

The early 99 tanks still had many defects, such as the engine had only 1200 horsepower, the transmission system was still planetary gears, and the fire control system was not advanced enough. These were the focus of later improvements. The engine was upgraded to 1500 horsepower, and there was even a 1800 horsepower version in the later period, hydraulic transmission, hunter-killer fire control, etc.

The later modification of the 99 tank has undergone a complete change in combat effectiveness, enough to rank among the world's first-class levels, which is also inseparable from the credit of General Mao.

This person came to see me, there must be something important, I have to see him!

Soon, General Mao, who was full of white hair, walked in. When Qin Tao saw his hair, he was stunned. General Mao was born in 1962 and is only in his forties now. He is full of white hair, all because of his busy work!

This is a person who has worked hard all his life for the development of the country's military industry! Qin Tao has always respected such people very much.

"Mr. Mao! Come, please sit down. You came to me. If you need any help, just tell me."

Mr. Mao nodded: "I know your time is precious, so I won't waste your time. I'll go straight to the point. Mr. Qin, we are currently preparing for the third phase tank improvement project, and one of our groups is demonstrating the feasibility of electric tanks."

Electric tanks? Qin Tao was speechless for a moment. Old Mao, electric cars are fine for fun, but electric tanks? Do you plan to make the tank explode more violently?

Qin Tao was about to shake his head, 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 make electric tanks, it means that the tank's acceleration will be very good, which is very useful for avoiding flying shells."

Qin Tao nodded. It was really the case. In the era of internal combustion locomotives, it was difficult to make an electric car that could reach 100 km/h in five seconds, but in the era of electric cars, a large number of electric cars can shout that they can reach 100 km/h in less than five seconds. Electric motors can easily achieve this with high torque.

"Electric motors have very few parts and are easier to maintain."

Qin Tao could only continue to nod. Yes, in the era of oil vehicles, routine maintenance was required every six months or a year, such as replacing three filters, but electric vehicles did not need to be maintained. Electric vehicles do not need any maintenance, and at most they just need to upgrade the system.

"For military bases, it is impossible to make fuel, but it is easy to make electricity..."

"Electric motors are easier to achieve automatic control, preparing for unmanned tanks in the future..."

Mr. Mao mentioned a lot of advantages. Qin Tao nodded in agreement with each one he mentioned. Yes, these are indeed advantages and must be agreed.

"Mr. Qin, so we are arguing about the issue of electrification of land main battle equipment."

Qin Tao nodded: "Yes, these are all advantages you mentioned, but electric drive not only has advantages, but also many disadvantages. The first and biggest disadvantage is where the electricity comes from. Our electric cars use 18650 batteries. You don't have this idea, do you? The island country uses this to build the AIP system of submarines. You should know the result, right?"

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

"Yes, so we want to find Mr. Qin, please give us some advice. We have found Golden Sun Company, and they said they don't know either."

Golden Sun Company is engaged in electric motors, and they are just doing electric cars by the way. They don't have any technical route planning. Whatever Qin Tao says to build, they will build it. It's that simple.

So now we can only come to Qin Tao

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

"Yes, I have considered it. If a tank is equipped with a nuclear power treasure, it will have unlimited endurance. However, once it is hit on the battlefield, it will be terrible. Our national defense policy is still defensive in nature, so this is not reliable." Mr. Mao nodded. They have studied it seriously and concluded that it is not appropriate.

The American soldiers have caused many problems with just some depleted uranium bombs. If they install nuclear reactors on these tanks and they are blown up on the battlefield, the consequences will be disastrous.

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

"Wireless power supply is even more inappropriate."

"That's right, it is impossible to bury power supply coils on the battlefield."

"So, there is only one way."

"What way?"

"Use internal combustion engines to generate electricity, and then use electric motors to drive tanks."

When hearing this, Xu Zhengyang on the side suddenly wanted to laugh. This is simply farting and taking off pants! Using oil to generate electricity and then using electricity to drive tanks, what's the point?

There are many similar systems on warships, which are called the ship-wide integrated power system. This is done because there are more and more electrical equipment on warships, and a suitable power distribution plan is needed.

What about tanks?

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

"Boss Qin, some large vehicles, such as mining vehicles, will adopt this solution, mainly because the power is too strong and the transmission device is not convenient to design. Our tanks have a complete transmission system. We have already developed a mature hydraulic transmission system. I am afraid there is no need to use this method?"

Electric transmission is used on large mining vehicles for convenience. After all, it is impossible for a vehicle with a wheel taller than a person to use mechanical shifting.

Speaking of using it in military vehicles, we have to mention Germany during World War II. At that time, Dr. Porsche liked to play with electric transmission and built a batch of chassis, which were said to be unable to go in a straight line...

"Oh, I didn't make it clear just now. It's not just internal combustion engines, generators, and electric motors, but also batteries."

Mr. Mao opened his eyes wide. Mr. Qin, we use electric drive, and one of the biggest features is the 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: "Internal combustion engines have various output curves. We can make the internal combustion engine work in the best output range to avoid repeated adjustment of the throttle. For vehicles with this structure, the engine either does not start, or it starts at a fixed speed."

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

Having studied vehicles for half his life, Mr. Mao certainly knows that car engines need to change speeds at all times to obtain different output powers to adapt to different situations, such as uphill and downhill, such as 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 has only a very narrow range in which it is most fuel-efficient.

There is no way to solve this problem.

The engine is adjusted up, and the car can't use it. The engine is adjusted down, and the car is not enough. How can this vehicle be used?

"There are batteries." Qin Tao said: "The battery is used as a buffer and compensation for power. For example, when the car is moving at a low speed, the power cannot be used, so the excess energy is stored in the battery. When the car needs to speed up or move at high speed, more power is needed, and the battery outputs electricity to allow the motor to output more power."

"Mr. Qin, do you mean hybrid?"

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

There are two types of hybrid vehicles. One is plug-in hybrid. The battery of this car is relatively large and can be plugged into a charging pile for charging. Pure electricity can travel dozens of kilometers or even hundreds of kilometers. It does not use oil at all in the city, and it will only use oil when it needs to go high.

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

The car consumes the most fuel when it starts, so let's use electric! The car wastes the most when it stops and starts, or when it waits for traffic lights, so let's use electric! At low speeds, electric is enough, and oil is used at high speeds. When the battery is gone, use oil to recharge!

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 depends on the usage requirements. If you often travel in urban areas, you must choose a plug-in hybrid. After all, you don’t need gasoline at all. You can charge it when it runs out. But if you drive on the highway and the battery runs out, you can only use gasoline. , at that time, it is equivalent to carrying a large battery for no reason to add extra weight, so it is more suitable to run at high speeds with gasoline and diesel.

So, which kind of equipment is more suitable for the army? Qin Tao recommends a large battery solution.

"Yes, hybrid power, but the battery must be large. It can drive about fifty kilometers on pure electricity. In this way, on the battlefield, it can handle various situations with ease. For example, in situations where it is inappropriate to make a noise. Next, you can use pure electricity to approach the enemy covertly.”

Mr. Mao opened his eyes wide, could he still play like this?

Electric vehicles have no sound. After all, they don’t need an internal combustion engine. They just use batteries to drive the wheels and make no noise. Especially wheeled vehicles, it’s exciting to think about quietly approaching the enemy on the battlefield.

Not only is there no sound, there is also no infrared ray. The internal combustion engine will inevitably bring heat, and the temperature of the exhaust pipe cannot be lowered. In the war in the desert area more than ten years ago, Silly Damu’s tank would be beaten even if it was buried under the sand. The explosion is due to the infrared rays radiated by the heat emitted by the engine.

Therefore, you can carry out sneak attacks in electric mode!

Mr. Mao felt that he had been opened up to a new way of thinking.

"At the same time, hybrid power can save fuel. Generally speaking, it is no problem to save 30% of fuel consumption. This means that if our tank is full of fuel, it can run for 500 kilometers, but now it can run for 6 Seven hundred kilometers.”

The cross-country travel of the tank, like the fuel consumption of the vehicle, is also greatly reduced.

For example, the German Leopard 2 tank, according to published data, has a range of 550 kilometers. It is actually run on the road. When it is on the battlefield and moving in the wild, the cross-country range will be reduced to more than 100 kilometers. kilometer.

The tank engine runs at high speed, but in fact it cannot run fast, and the power is wasted, just like a vehicle stopping and going in the city. If it is replaced with a hybrid power, the battery will play a huge role. Qin Tao said it saves 10% Thirty is just a conservative estimate. In fact, a 50% increase in the itinerary is not a problem.

The troops are not short of fuel, but the troops' fuel also requires a large number of vehicles to transport! If fuel can be saved, it means that supply needs will be lower, and the troops are willing to see this result.

"As for the complexity of the system, I think it is not unacceptable. Although batteries, generators and electric motors have been added, the power of the engine can be smaller, the size can also be reduced, and it can save fuel. Overall, it is still worth it. ”

Qin Tao almost said it wrong. He originally wanted to say that it was not that complicated. Although there were more things, it also saved the gearbox. But when he thought about it, it was wrong. If the gearbox was omitted, the engine would not be able to drive the vehicle. To generate electricity, you must know that at high speeds, hybrids should be driven by the engine and motor together, which requires a complex drive system.

The specific design will depend on the needs of the army, so he can't tell you everything.

As Qin Tao introduced, Mao kept nodding, just as Qin Tao agreed with him just now. When Qin Tao finished speaking, Mr. Mao was very excited: "Mr. Qin, the plan you mentioned is very good, but this motor drive We don’t understand. Can you ask Golden Sun Company to provide us with supporting equipment?”

Qin Tao suddenly realized, no, he had been fooled.

The people in front of me are engaged in tanks and vehicles. Do they know about hybrids? Although Golden Sun Motors is taking the pure electric route, there are still many car manufacturers in the world, especially in island countries. Toyota began research and development of hybrids in the 1970s. In 1997, the first-generation Prius It was launched and equipped with a THS hybrid system, becoming the world's first mass-produced hybrid vehicle.

It's just that they are taking the road of oil and gas and are not plugged in.

Mr. Mao and the others must have studied related technologies, and naturally they also know that pure electric solutions are not suitable for tanks and armored vehicles, so they want to develop hybrid solutions. The problem is, they have no technology!

Only Golden Sun Motor Company has this capability, but Golden Sun Company only operates pure electric vehicles, not hybrids. Therefore, it was useless for Mr. Mao to go there, so he simply came to Qin Tao. After some research, he believed that hybrid electric vehicles are the best choice. It's appropriate. So, do we have to ask Mr. Qin for help next?

Qin Tao has been the leader for so many years, but he didn't expect to be tricked by his own people. Thinking of this, he looked at Mr. Mao with a complicated look.

"Mr. Qin, what's wrong with you?"

"What do you think is wrong with me? Mr. Mao, I have already told you that you have something to say, and yet you go around in such a big circle."

"No, what kind of detour did I make? Mr. Qin, you misunderstood!"

Qin Tao looked at Mr. Mao with his white hair and felt really embarrassed. Come on, Mr. Mao, please drive him away. After all, it’s all for the development of the motherland’s military industry!

"Mr. Mao, if you have any plans, just tell me directly."

"Mr. Qin, we believe that hybrid drive is the future direction of development, but we don't have the technical reserves. We want to ask Golden Sun Motor Company to help with matching. You have various power distribution solutions on warships, which can be easily transplanted to our vehicles. At the same time, in order to reduce the difficulty, we want to start with the modification of wheeled infantry fighting vehicles, and then transplant them to tanks after they are mature."

"Golden Sun Company is not good. This company is pursuing the pure electric vehicle solution. If we want to do hybrid now, it will cause the outside world to question our development route." Qin Tao refused.

Mr. Mao's eyes showed disappointment. No? Mr. Qin is unwilling to help?

"However, we can set up a hybrid R\u0026D company to develop hybrid technology, which can not only provide matching for military vehicles, but also for other car companies."
