MTL - Warship of Great Power-Chapter 716 Electric cars and electromagnetic guns

  Chapter 716 Electric cars and electromagnetic guns

Hearing Qin Tao's words, Ma Ming looked over curiously: "President Qin, if we build our own car factory, it will cost a lot of money, even if it is a closed car factory, it will be even 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 start an industry. Let others do the OEM, and we just make PPT cars, and then drive the stock price. What's the meaning?"

  Qin Tao wants to work hard in a down-to-earth manner. In later generations, there are many types of electric vehicle manufacturing companies. The first one has its own car factory with a huge output, which is equivalent to the sum of the production capacity of the last few. Well, the last few do not have their own car factories, and they only need to purchase some parts. , Assemble it in the foundry, and then carry out various packaging, it can be sold at a high price, and it looks taller.

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

  Since Qin Tao wants to develop electric vehicles, he must actually do it. He must have his own automobile factory. As for investment, there is no way to do business without spending money.

  Golden Sun actually has two routes for electric vehicles. They can only conduct research and development, and then sell the research and development results to the automobile factory, so that the automobile factory can do it. But in this era, it is estimated that no traditional car factory has the courage to make big strides towards electric vehicles, so it still has to do it by itself.

"Nowadays, there are many automobile factories in China that can't keep up with the development of the times and are gradually falling behind." Ma Ming said: "For example, Feihu, Red Star, Camellia, etc., but these automobile factories are heavily in debt, and the factories are only There are people who are not capable, and if we buy it, it will take 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 the workers in the factory are all mixed up with old fritters. It is not easy to change. It can be said that no matter how much money is invested, it may be in vain.

   "Besides, the cities where these auto factories are located are not big. After we acquire them, we have to send people there. Many people are used to Huating and don't want to go to small places."

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

   Qin Tao had already thought about this, but he hadn't discussed it with Ma Ming in detail.

  Huating is of course the place to manufacture cars. After all, there is a complete automobile industry chain here, and it is easy to attract talents. Who doesn’t want to stay in a big city like Huating?

  However, he is unwilling to depend on others, so he can only buy a bankrupt automobile factory, not for anything else, just for that qualification, or what is called a birth certificate.

Not everyone can build a car casually, they have to have status. Before the reform of the country, domestic auto factories, large and small, were all well-known and directly qualified to make cars. However, follow-up car manufacturers, especially private companies Well, it's not easy to build a car. Even if the local government gives the green light, it's useless if the superior doesn't issue a certificate.

  If this problem is not solved, the cars produced will not be able to get license plates and have no household registration.

There are many solutions, one of which is to acquire a bankrupt automobile factory to obtain qualifications. Even if Qin Tao is well-known in the military industry, it has nothing to do with the automobile industry. If he wants to enter this market, he can only Take this kind of curve to save the country.

   "Will the price be a bit high?" Ma Ming asked cautiously.

   Just to buy a car qualification, and then buy the entire car factory? Even if it is 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 and built a factory here in Huating. The original automobile factory can be completely flattened, and then we can build a building. The infrastructure department of Mingzhou Group should also contribute to local construction."

  The car factories in the past were all built in the center of the city, or in other words, many cities developed around the factory. After buying a car factory, you can definitely make a lot of money by flattening the building. 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 a port, building a shipyard, etc. However, if there are some opportunities to help a certain place develop urban construction, That is also very normal.

  At this time, hearing Qin Tao say this, Ma Ming understood a little bit, and Wu Shengli, who was sitting by the side, said with a smile: "Are you going to be a developer?"

   "We still focus on industry, and we can just do construction as we go along. If we specialize in real estate development, forget it."

Wu Shengli nodded: "There are still many imperfections in our country's policies, and many of them will be gradually released. In the future, if you want to engage in the automobile industry, your superiors should be able to let go. Now you are doing this, and it is the only one. I support the method. However, can your electric vehicle technology be used in the military?"

  Wu Shengli still cares about the development of military industry.

  Hearing his words, Qin Tao nodded without thinking, "Of course. Dad, our electric vehicle technology can of course be extended to the military industry."

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

  Army equipment never cares about fuel consumption or exhaust emissions, but performance! If the army vigorously promotes electric vehicles, once the electricity is out, it will take several hours to charge. Isn’t this a pitfall?

"For example, in order to pursue higher underwater endurance, the conventional power submarine of the islanders intends to replace the lead-acid battery with a lithium battery, so as to greatly improve the underwater endurance without changing too much." Qin Tao said: "In the future, when our technology is mature, we can use the same solution at any time."

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

  For example, the Germans are taking the fuel cell route. It is very high-handed, but in fact, their fuel cells have never worked properly, which has repeatedly caused submarines to lie down. In later generations, even the powerful German submarine force did not have a submarine that could be on combat readiness, or it was under maintenance. , or it is on the way to repair.

  In addition to these routes, the battery is replaced directly. The lithium battery has a high energy density, can store more electric energy, and is very convenient to refit, so it is the most suitable layout.

  Of course, before we try it, we use mature lead-acid batteries first, and 18650 batteries are stacked in diesel-electric submarines. The number is many times that of electric vehicles, and the failure rate will be higher.

   Hearing what Qin Tao said, Ma Ming came to his senses and nodded with satisfaction: "That's right, the plan Mr. Qin said is feasible, but you have to take your time and don't rush for success."

   "We will also develop self-driving technology for electric vehicles. These technologies will also have a great effect on military equipment." Qin Tao continued.

   Ma Ming's eyes lit up again, Mr. Qin is amazing, he can't think of these things, but Mr. Qin can think of them!

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

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

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

  Power, steering, and braking are all controlled by electric motors, so they can be controlled by computers! Autopilot has begun to take shape, and our own Beidou has also been launched into the sky, and functions such as positioning are no longer a problem.

   Wait, there seems to be a key problem!

   "Mr. Qin, how to solve the problem of sensors in our automatic driving technology?" Ma Ming asked: "This is different from the automatic driving of airplanes. The situation on the road is very complicated."

  Spacecraft also has automatic control. The pilot of the airliner can take off and land automatically, and fly automatically without even moving anything. However, the sky is high and the ground is not so open.

  Various vehicles, pedestrians, traffic lights, if these conditions cannot be observed, then automatic driving cannot be successful.

   "This problem is not a problem." Qin Tao said: "You can use lidar, or you can use vision algorithms, but you don't have to worry about these, just leave it to the goose factory to do it."

Qin Tao's trust in Goose Factory is also growing, and he has long since given up the idea of ​​just making a vote and leaving. Even in the dot-com bubble, Goose Factory will continue to develop. They have developed into a major Internet company. There are also many solid products.

LiDAR is a bit early, it is expensive and has simple functions, so you can use the visual algorithm for the time being. After this thing is developed, it will be very useful. Golden Sun electric vehicles are sold all over the world, and the situation in various places can be seen through the on-board camera. Income into the database to go!

  In particular, electric vehicles 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 full of expectations. After five years, or even ten years, this Golden Sun car will become the main source of profit for their Golden Sun company!

  Since Qin Tao said that he will hand it over to the 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, and the rest should be left to professional people.

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, so don't worry , Just fiddle with it slowly, if you fiddle with this thing too fast, it may be prone to problems.

   "Mr. Qin, when these problems are resolved, what will our car look like? Is it 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 force. This car is so expensive that General Motors does not plan to sell it. Instead, it rents it out to special customers. Rich people can't afford it.

   This kind of car is a high-end car, so it is a two-door sports car. It is not a normal family car anyway, and the characteristics of the electric motor: large torque and fast speed-up, are just in line with the characteristics of a sports car. It is difficult for a normal family car to accelerate from 0 to 100 within five seconds, and even within ten seconds is a good car. However, electric vehicles can easily run within five seconds, and even by stacking batteries, they can still go three or four It breaks 100 in seconds, overwhelming those V8 or even V12 engines. Of course, after breaking 100, it will be discouraged, because there is no gearbox, so the top speed performance is very poor.

   Now, what will Golden Sun's first electric car look like?

   "Five-door sedan, but the appearance must be stylish and close to a sports car." Qin Tao only gave a rough idea, and how to do it depends on the designer.

   "We are all laymen. Please invite an international car design master to come and tell him that we are going to develop environmentally friendly electric cars. Such people will definitely be interested." Qin Tao said.

   Ma Ming nodded, this matter is considered to be discussed properly. And the plane finally arrived in the capital, and the special car took them straight to Gongzhufen. When they arrived at the Yellow Tower, after a cup of tea, the meeting was held.

"This visit to Huangdi Village left a deep impression on me." Wu Shengli said to everyone: "Unknowingly, we have already possessed technology that is ahead of the entire era. We have electromagnetic ejection and electromagnetic blocking. The technology has performed very well, and it is a generation ahead of the ones used on American aircraft carriers. Now, our scientific researchers are still working hard to make even more impressive achievements in the field of electromagnetic guns. This time, It is the demonstration meeting of 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 no longer let our research and development institutions always raise their own funds."

"I think the first question that needs to be considered is what is the advantage of electromagnetic guns, what is the improvement compared with our existing artillery, and whether it has reached the time to use electromagnetic guns to replace chemical guns. After all, this is the same as electromagnetic ejection There is also electromagnetic blocking, in our navy's equipment, the role of naval guns has been greatly reduced." A leader said.

  During the two world wars, caliber was justice and tonnage was truth. Battleships were built bigger and bigger, and naval guns were thicker and thicker. If World War II had not ended, it is estimated that 800mm naval guns could come out.

However, after the end of World War II, battleships were quickly eliminated, aircraft carriers became the overlord of the sea, carrier-based aircraft became the main attack weapon, and ordinary destroyers and frigates also began to use anti-ship missiles as the main force. The naval guns on board have almost become soy sauce, which can be seen from the number: generally it is a main gun, plus a few multi-barreled rapid-fire guns.

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

  Electromagnetic gun is still an upgraded model of ordinary naval gun. What is the use of it? In modern warfare, is it already a tasteless existence?

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

"Everyone, Ma Gong will answer the technical questions, and I can answer this question." Qin Tao looked at the crowd: "In modern warfare, the presence of ordinary naval guns is getting weaker and weaker, but this is just The range and power of ordinary naval guns are not enough, and the electromagnetic gun just makes up for this shortcoming."

  Of course, there is no need for Ma Ming to explain this kind of small problem. After all, Ma Ming is engaged in technology.

"Currently, the muzzle kinetic energy of the main naval gun is around 20 megajoules, and the muzzle kinetic energy of the next-generation 155mm naval gun that the U.S. Navy plans to use will reach about 32 megajoules, which is already the limit that modern naval guns can achieve. Even if it is to launch a rocket with an extended range, the maximum range is only 100 nautical miles, which is 185 kilometers. However, the muzzle kinetic energy of our electromagnetic gun can be quickly increased with the advancement of technology. For example, the electromagnetic gun we want to develop, a The most basic requirement is that the kinetic energy of the muzzle reaches more than 32 megajoules, and 64 megajoules is the most basic setting. Under 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 is hit, it can still maintain 17 megajoules of energy, do you think such a naval gun is still tasteless?"

   This is a proper ballistic missile!

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

  Many anti-ship missiles have a range of only a hundred kilometers, and the air defense range of many fleets cannot be extended to two hundred kilometers, but now? What is the concept that a naval gun can launch an attack on a target 400 kilometers away?

   "Can the electromagnetic gun hit so far?" Everyone present was shocked.

"Yes, the power of gunpowder has reached its limit, but electromagnetic guns have 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 advantages in range, rate of fire, strike power and ammunition far exceed traditional artillery, do you still think electromagnetic guns are tasteless?"

   "With such a long range, its accuracy will drop a lot, right?" Someone said.

  The range is 10 kilometers to 20 kilometers, and the accuracy can still be guaranteed. If it is 30 to 40 kilometers, it is not accurate enough. If it is 300 to 400 kilometers, then it will not know where it will fly.

   "That's right, it's useless if it only flies far without enough accuracy. 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 400 kilometers, the accuracy of ballistic missiles cannot be guaranteed? Advanced ballistic missiles can even be maintained within ten meters."

   "Boss Qin, what do you mean, there will be some electronic components inside the cannonball? I'm afraid that would be too much, right? Will these electronic components not be damaged due to overload when fired?" Someone asked again.

  Ballistic missiles are accurate, not only because of the ballistic trajectory, but because of the inertial navigation system on them. Now, Qin Tao compares this kind of artillery shells with missiles, which must have electronic equipment inside.

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

To fly so far, a guidance system must be added. However, overload is not a big problem. The tank's gun-launched missile needs to be fired from the barrel, and the electronic components of the shell inside still have to withstand the impact. Moreover, the artillery is the same as the catapult , the speed is zero and the acceleration is the maximum when it is just launched. As the expanding gas works inside, the pressure gradually decreases, and the acceleration also gradually decreases.

   But the electromagnetic gun is different, the acceleration is the same throughout the whole process. Of course, with the same barrel length, the electromagnetic gun requires a higher 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 problem facing the electromagnetic gun shell guidance system.

"Compared to overload, the most serious problem our electronic system faces is the strong magnetic field." Qin Tao said: "The inside of the electron gun needs a strong magnetic field, and we all know that during the movement of electrons, they will be affected. deflected by the influence of the magnetic field."

  Electric field doesn’t matter, it can be solved directly with shielding cover, but this magnetic field is really hard to counteract, so we can only study how electronic components work under strong magnetic field, or use special components, such as quantum chips and so on.

  Everyone listened carefully.

"This is a major technical problem that we need to solve, but I believe that we have the ability to solve this problem. After we solve it, we can usher in the spring of electromagnetic guns. We have even developed electromagnetic catapults. Of course, electromagnetic guns It’s not a problem, and our aircraft is not affected by the strong magnetic field.” Qin Tao didn’t elaborate on this issue, anyway, these people present didn’t understand, and if they mentioned quantum chips to them, they would definitely think it was a fairy tale. Now this kind of flickering is over. In fact, the fighter plane is outside the electromagnetic catapult, while the shell of the electromagnetic gun is inside the electromagnetic field. This is a big difference.

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

   Qin Tao mentioned this idea before, but he didn't elaborate on it. Now that this meeting is of great importance, Qin Tao has to talk about these grand blueprints again.
