Chapter 716 Electric Cars and Electromagnetic Guns

Hearing Qin Tao's words, Ma Ming looked over curiously: "Mr. Qin, if we build our own car factory, it will cost a lot of money, even if it is a bankrupt car factory, it will be no exception, and it will even be more complicated. Why don't you agree? SAIC OEM?"

"We want to build our own industrial chain. We are electric vehicles, which are different from those fuel vehicles. Moreover, since we want to do it, we have to engage in industry and let others do the manufacturing. We just make PPT cars and then increase the stock price. What's the point? What's the meaning?"

 Qin Tao wants to be down-to-earth and work hard. In later generations, there are many types of electric vehicle manufacturing companies. The number one company has its own car factory and its output is huge, equivalent to the combined production capacity of the next few companies. The next few companies do not have their own car factory and only need to purchase some parts. , assembled in a foundry, and then packaged in various ways, they can be sold at a high price, making them look classy.

　　How high the stock value is, that’s all just talk. If you don’t even have your own factory, what else can you have?

Since Qin Tao wants to develop electric vehicles, he must do it in a real way. He must have his own automobile factory. As for investment, there is no way to build an industry without spending money.

Golden Sun Electric Vehicle actually has two routes. They can only engage in research and development, and then sell the research and development results to automobile manufacturers for them to do the work. But in this era, it is estimated that no traditional car manufacturer has the courage to take a big step towards electric vehicles, so they still have to do it themselves.

"There are many automobile factories in China that cannot keep up with the development of the times and are gradually falling behind." Ma Ming said: "For example, Feihu, Red Star, Camellia, etc. However, these automobile factories are heavily in debt, and the factories only have There are only incompetent people left, and if we were to acquire them, we would have to expend a lot of effort."

Ma Ming really didn’t want to do this. Just thinking about it made him feel overwhelmed.

All bankrupt companies have a common problem: poor management, backward technology, and workers in the factory are all old-timers. It is not easy to change. It can be said that no matter how much money is invested, it may be wasted.

“Moreover, the cities where these car factories are located are not big. After we acquire them, we have to send personnel there. Many people are used to being in Huating and are unwilling to go to small places.”

Qin Tao nodded: "Well, the problems you mentioned are all problems, but they are not problems. We only acquire their car-making qualifications, and then we build a car factory in Huating and build cars ourselves."

Qin Tao has already thought about this, but he has never explained it to Ma Ming in detail.

Of course, cars must be built in Huating. After all, there is a complete automobile industry chain here, and it is also easy to attract talents. Who doesn’t want to stay in a big city like Huating?

 However, he was unwilling to rely on others, so he could only buy a bankrupt automobile factory for no other reason than for the qualification, or birth certificate.

Not everyone can just build a car, they have to have status. Before the country carried out reforms, domestic automobile factories of all sizes had benefited from it, and they were directly qualified to build cars. However, subsequent car-making companies, especially private enterprises, were , It is not easy to build a car. Even if the local government gives the green light, it will be in vain if the superiors do not issue a certificate.

 If this problem is not solved, the cars produced will not be able to get license plates and will not have household registration.

There are many solutions. Acquisition of a bankrupt automobile factory to obtain qualifications is one of them. Even if Qin Tao is famous in the military industry, it has nothing to do with the automobile manufacturing industry. If he wants to enter this market, he can only Take this curved approach to save the country.

“Is this price too high?” Ma Ming asked cautiously.

 Just to buy a car qualification, and then buy the entire car factory? Even for a bankrupt car factory, the price is not low.

Hearing Ma Ming's words, Qin Tao shook his head: "Of course not. We bought the qualifications to build a factory here in Huating. The land where the original automobile factory was was can be completely bulldozed and then build a building. We Mingzhou Group’s infrastructure department must also contribute to local construction.”

 In the past, automobile factories were all built in the centers of cities. In other words, many cities were developed around factories. After buying a car factory and razing it to build a building, you can definitely make a lot of money. In this era, real estate is definitely the most profitable.

Mingzhou Group is engaged in industry. Even if it has an infrastructure department, it is engaged in big business, such as building ports and shipyards. However, if it encounters some opportunities to help develop urban construction in a certain place, That's normal too.

At this time, after hearing what Qin Tao said, Ma Ming finally understood something. Wu Shengli, who was sitting next to him, said with a smile: "Are you going to be a developer?"

“We still focus on industry, and we can just do construction as long as it’s convenient. If we specialize in real estate development, forget it.”

Wu Shengli nodded: "Our country's policies still have many imperfections, and many of them will be gradually liberalized. In the future, if you want to engage in the automobile industry, your superiors should be able to relax. Now you are doing this, and this is the only way. I support this approach. However, can your electric vehicle technology be used in the military?"

Wu Shengli is still concerned about the development of military industry.

Hearing what he said, Qin Tao nodded immediately without thinking: "Of course. Dad, of course our electric vehicle technology can be extended to the military industry."

Ma Ming frowned, Mr. Qin, this is a big statement!

 For military equipment, we never care about fuel consumption or exhaust emissions. What matters is performance! If the military vigorously promotes electric vehicles, then once the battery runs out, it will take several hours to charge. Isn’t this a pitfall?

"For example, in order to pursue higher underwater endurance for the conventionally powered submarines of the island nation, they plan to replace the lead-acid batteries with lithium batteries, thereby greatly improving the underwater endurance without making too many changes." Qin Tao said: "In the future, when our technology matures, we can use the same solution at any time."

The domestic choice is the Stirling engine. Although the output power is low and can only meet the low-speed underwater navigation capability, this engine is very reliable. This has been verified in the last exercise between the Pyramid State and the US Navy. Of course , there are other routes.

For example, the Germans are taking the fuel cell route. They were boasting very high-end, but in fact, their fuel cells never worked properly, often causing submarines to lie down. In later generations, even the powerful German submarine force did not have a single submarine that could be on combat readiness duty, or was under maintenance. , or it is on the way to repair.

 In addition to these routes, the battery is directly replaced. Lithium batteries have high energy density, can store more electricity, and are easy to modify, making them the most suitable layout.

Of course, before we try it, we will first use mature lead-acid batteries. There are 18,650 batteries in the diesel-electric submarine. That number is many times that of electric vehicles, and the failure rate will be higher.

Hearing what Qin Tao said, Ma Ming reacted and nodded with satisfaction: "Yes, the plan that Mr. Qin said is feasible, but you have to take your time and not rush for success."

“We will also develop autonomous driving technology for electric vehicles, which will also play a great role in military equipment.” Qin Tao continued.

Ma Ming's eyes lit up again. Mr. Qin is so awesome. He couldn't think of these things, but Mr. Qin can think of them all!

The key to electric vehicles is the three electric vehicles, but other systems must also be modified according to electric standards. For example, the steering assist system can use an electric motor as a boost. If the existing hydraulic power steering is used, a special system will be required. hydraulic booster pump.

The same is true for braking. Traditional car brakes use engine vacuum assist, which uses the vacuum created by the engine when it inhales to increase braking force. But in electric cars, there is no vacuum created by the piston engine's inhalation. What should I do? ? Therefore, the brakes must also be electric brakes, and electric brake pumps are specially manufactured.

 Everything is controlled electronically, which creates opportunities for autonomous driving.

 Power, steering, and braking are all electrically controlled, so they can be completely controlled by a computer! Autonomous driving has begun to take shape, and our own Beidou has also been launched into the sky, and positioning and other functions are no longer a problem.

 Wait a minute, there seems to be another key question!

“Mr. Qin, how do we solve the problem of sensors in our autonomous driving technology?” Ma Ming asked: “This is different from the autonomous driving of airplanes. The situation on the road is very complicated.”

There are also automatic controls on the spacecraft. The pilot of the passenger plane can take off and land automatically and fly automatically without even having to do anything. But the sky is high enough for birds to fly, and the ground is not that empty.

 If various vehicles, pedestrians, and traffic lights cannot be observed, autonomous driving will not be successful.

“This problem is not a problem.” Qin Tao said: “You can use lidar or visual algorithms, but you don’t have to worry about these, just leave it to Goose Factory.”

Qin Tao's trust in Goose Factory is also growing. He has long given up the idea of ​​​​leaving away after one vote. Even if it encounters the Internet bubble, Goose Factory will continue to develop. They have developed into a major Internet company. There are also many real products.

Lidar is a bit old, expensive and has simple functions, so we can use visual algorithms for the time being. After this thing is developed, it will still be of great use. Golden Sun electric cars are sold all over the world, and the conditions in various places can be monitored through on-board cameras. Into the database!

Especially, electric cars are still high-end products, and only high-end people have the capital to use them. Wherever they go, they are all good places!

Thinking of this, Qin Tao is even more full of expectations. After five or even ten years of work, this Golden Sun Automobile will become the main source of profit for their Golden Sun Company!

Since Qin Tao said it would be handed over to Goose Factory, Ma Ming doesn’t have to worry about anything. He is really not good at this kind of thing. What he is good at is power supply and motor. The rest can be left to professionals.

Qin Tao is not particularly concerned about the electric vehicle project. After all, in his eyes, this project is not a military project, but a civilian profit-making project. Anyway, Mingzhou Group is not short of money, and Golden Sun Motor Company is not short of money either, so there is no need to worry. , just tinker with it slowly. If you tinker with this thing too fast, it may be easy to cause problems.

“Mr. Qin, when these problems are solved, what will our car look like? Will it be a two-door sports car or a five-door sedan?”

At present, the only mass-produced electric car in the world is General Motors' Impact. This car is so expensive that General Motors does not plan to sell it. Instead, it rents it, and the customers it leases to are still very special. Rich people can't afford it for ordinary people.

This kind of car is high-end, so it uses a two-door sports car style. It is not a normal family car anyway, and the characteristics of the electric motor: large torque and fast speed increase are exactly in line with the characteristics of a sports car. It is difficult for a normal family car to accelerate from 0 to 100 mph in less than five seconds, and any car that can accelerate from zero to 100 seconds is considered a good car. However, electric cars can easily accelerate within five seconds, and even with the help of stacked batteries, they can still do three or four seconds. It can break 100km/h in seconds, beating those V8 or even V12 engines. Of course, it gives up after it breaks 100km/h. Because there is no gearbox, the top speed performance is very poor.

Now, what should Golden Sun’s first electric car look like?

“It’s a five-door sedan, but the appearance must be eye-catching and close to a sports car.” Qin Tao only gave a general idea. How to make it specific depends on the designer.

“We are all laymen. If we invite an international car design master to come over and tell him that we are going to build environmentally friendly electric cars, such people will definitely be interested,” Qin Tao said.

Ma Ming nodded, the matter was considered settled. The plane finally arrived in the capital, and a special car took them straight to Princess Tomb. After arriving at Huanglou, after having a cup of tea, the meeting was held.

"This trip to Wasteland Village left a deep impression on me." Wu Shengli said to everyone: "Unknowingly, we already have technology that is ahead of the entire era. We have electromagnetic ejection and electromagnetic interception. The technology has performed very well and is one generation ahead of that used on American aircraft carriers. Now, our scientific researchers are continuing to work hard to achieve even more outstanding results in the field of electromagnetic guns. This time, It is a demonstration meeting for our electromagnetic gun. If it passes this time, the Navy will also allocate funds to support the research and development of our electromagnetic gun, and we will no longer let our research and development institutions always raise funds by themselves."

"I think the first question that needs to be considered is what are the advantages of electromagnetic guns, what improvements are there compared to our existing artillery, and whether it is time to use electromagnetic guns to replace chemical cannons. After all, this is not the same as electromagnetic catapults. There is also a difference in electromagnetic interception. In our navy's equipment, the role of naval guns has been greatly reduced." A leader said.

 In the two world wars, caliber was justice and tonnage was truth. Battleships were getting bigger and bigger, and naval guns were getting thicker. If World War II had not ended, it is estimated that 800 mm caliber naval guns would have been produced.

However, after the end of World War II, battleships were quickly eliminated. Aircraft carriers became the dominant force on the sea. Carrier-based aircraft became the main attack weapon. Ordinary destroyers and frigates also began to use anti-ship missiles as their main force. Up to now, each warship The naval guns on board have almost become soy sauce, which can be seen from the number: generally there is only one main gun, plus a few multi-barreled rapid-fire cannons.

 However, a large number of various missiles, anti-ships, and air defenses have become the main force.

 The electromagnetic gun is still an upgraded version of the ordinary naval gun. What is its use? In modern warfare, is it already useless?

 If there is no suitable answer to this question, then there is no need to launch the electromagnetic gun project at all.

"Everyone, the technical questions are answered by the horse workers. I can answer this question." Qin Tao looked at everyone: "In modern warfare, the presence of ordinary naval guns is getting weaker and weaker, but this is just This is caused by the insufficient range and power of ordinary naval guns, and the electromagnetic gun just makes up for this shortcoming."

Of course there is no need for Ma Ming to explain such a small problem. Ma Ming is engaged in technology after all.

"Currently, the muzzle kinetic energy of main naval guns is around 20 megajoules. The next-generation 155mm naval guns planned to be used by the U.S. Navy will have a muzzle kinetic energy of around 32 megajoules. This is already the limit that modern naval guns can achieve. Even if we launch rocket extended-range projectiles, the range is only 100 nautical miles at most, which is 185 kilometers. However, the muzzle kinetic energy of our electromagnetic gun can be quickly improved with the advancement of technology. For example, the electromagnetic gun we want to develop, a The most basic requirement is that the muzzle kinetic energy reaches more than 32 megajoules, and 64 megajoules is the most basic setting. At this energy, if the shell is 20 kilograms, it can hit the target at 220 nautical miles, which is about 407 kilometers. , when the warhead hits, it can still maintain 17 megajoules of energy. Do you think this kind of naval gun is still useless?"

 This is a proper ballistic missile!

  The range of ordinary naval guns is only a dozen kilometers, so shooting at sea is useless, and shooting at land is also useless. However, what if the range is expanded to 200 kilometers, or even more than 400 kilometers?

 Many anti-ship missiles only have a range of a hundred kilometers, and the air defense range of many fleets cannot be extended to two hundred kilometers. But what about now? A naval gun can attack a target four hundred kilometers away. What is the concept?

 “Can the electromagnetic gun shoot so far?” Everyone present was shocked.

"Yes, the power of gunpowder has reached its limit, but the electromagnetic gun has just started. In the future, with more advanced energy storage devices and better electromagnetic components, the range will be further increased." Qin Tao said: "The electromagnetic gun is in The advantages in range, rate of fire, strike power and ammunition are far greater than those of traditional artillery. Do you still think electromagnetic guns are useless?"

“With such a long range, its accuracy will also drop a lot, right?” someone said.

 With a range of ten kilometers or twenty kilometers, the accuracy can still be guaranteed. At thirty or forty kilometers, it is no longer accurate. At three or four hundred kilometers, it is even less accurate where it flew.

“Yes, it’s useless if it only flies far and is not accurate enough. At such a long distance, the error can even be as high as ten kilometers or more.”

“Everyone, you can think of it as a ballistic missile. With a range of four hundred kilometers, ballistic missiles cannot guarantee accuracy? Advanced ballistic missiles can even stay within ten meters.”

“Mr. Qin, what do you mean, are there some electronic components inside the shell? Isn’t that too harsh? Won’t these electronic components be damaged due to overload when launched?” Someone else asked.

The ballistic missile is accurate not only because of its trajectory, but also because of the inertial navigation system mounted on it. Now, Qin Tao compared this kind of artillery shell with a missile, which must have electronic equipment inside.

"Our army's tanks are already equipped with gun-launched missiles." Qin Tao said: "You can ask how they solve the overload problem. Unless it is an electronic tube, the overload that a normal integrated circuit can withstand is still very large. , can still work normally under an overload of 30000G, and is not afraid of the acceleration of our electromagnetic gun at all. Moreover, the acceleration of the electromagnetic gun is more uniform, accelerating the shell to the same speed, and the electromagnetic gun shell withstands less overload. "

To fly that far, a guidance system must be added. However, overload is not a big problem. The tank's gun-launched missiles need to be launched from the barrel. The electronic components of the shells inside still have to withstand the impact. Moreover, the artillery and catapults are the same. , the velocity is zero and the acceleration is maximum when it is just launched. As the expanding gas works internally, the pressure gradually decreases, and the acceleration also gradually decreases.

 The electromagnetic gun is different, the acceleration is the same throughout the entire process. Of course, with the same barrel length, the electromagnetic gun requires a greater terminal velocity, so its acceleration is much greater than that of the gunpowder gun, but these are not problems.

These people still look at the problem with the old thinking of the past and have not found the real problems faced by the electromagnetic gun shell guidance system.

"Compared with overload, the most serious problem our electronic systems face is caused by strong magnetic fields." Qin Tao said: "The electron gun requires a strong magnetic field inside, and we all know that electrons will be affected by deflected by the influence of the magnetic field.”

The electric field doesn't matter, it can be solved directly with a shield, but the magnetic field is really difficult to offset. We can only study how electronic components work under strong magnetic fields, or use special components, such as quantum chips, etc.

Everyone listened very carefully.

"This is a major technical problem that we need to solve, but I believe that we have the ability to solve this problem. Once solved, we can usher in the spring of electromagnetic guns. We have even developed electromagnetic catapults, and of course electromagnetic guns It's not a problem, and our carrier aircraft is not affected by the strong magnetic field." Qin Tao did not elaborate on this issue. Anyway, these people present did not understand it. If you mention the quantum chip to them, they will definitely think it is a fantasy. Now this deception is over. In fact, the fighter plane is outside the electromagnetic catapult, while the electromagnetic gun shells are inside the electromagnetic field. This is a big difference.

“What I just mentioned is just a normal use of the electromagnetic gun.” Qin Tao continued: “In addition to the upgrade of ordinary naval guns, the electromagnetic gun also plays an important role, and that is anti-missile.”

Qin Tao has mentioned this idea before, but he did not explain it in detail. Now this meeting is of great importance, and Qin Tao has to talk about these grand blueprints again.
