Tower Defense Strategy

Norn Electromagnetic Laboratory was established by Norn Weil, who holds more than 20 patents, and Tongyong Electric.

Our laboratory has been a partner of PRADA for a long time, and the goal is to provide electromagnetic main guns for new warships.

As a result, because of the well-known principle of "the money of the local tyrants are returned, and the people’s money is divided into three to seven", the money that was given to the laboratory by the same use of electricity disappeared on the book, and the money of PRADA was also used with Noen to make a fortune. , The remaining point, of course, is not enough.

Finally, the shipboard electromagnetic main gun failed to be delivered due to "technical reasons".

But no matter what, the Nuoen laboratory does have the closest practical electromagnetic weapon technology in country A, so it faces the threat of monsters. It is one of the few laboratories funded by PRADA.

After getting the new grant, I discussed with the scientists and laboratory members who use electrical appliances. I felt that I could barely get on the horse if I made the caliber smaller. I just started the relationship again. I got an order from the pit of the hexagonal building. Anyway, the hexagonal building now has money. There is nowhere to go.

The superconductor series "Black and White Magic Guide" flowed directly from the mouth of the octopus to the C State 277 Institute. Because of the book title, although it is clearly in the library, it has not received other attention in the short term.

Naturally, the Nuoen laboratory did not use new superconductors. In fact, country A did not create a game and reality integrated interactive system like country C. Even if you get the book, you still need to go through demonstration, verification, and trial production. , I won’t be able to use new materials for a while.

The delivery is a 30mm caliber. Old-fashioned superconducting materials are still used. The superconducting temperature is around 200K, and the initial velocity of the projectile reaches 10,000 meters per second. In the experiment, it penetrated three kilometers away and one meter thick. Concrete wall.

The disadvantage is that the launch frequency is a bit general, five shots a minute.

This value is not certain, but it can maintain this rate of fire on the new battleship Dazhu, and it can be faster if it is deployed in a fixed facility.

In any case, this is also an electromagnetic weapon. The major media reported a wave of joy. Our country A is indeed invincible, far from being comparable to that of the braids on the other side of the planet.

Understand that people are either blowing ignorant of their conscience, or they have no right to speak, and only feel sad in their hearts.

The so-called muzzle velocity of a projectile is actually a word game, and its power depends only on the speed of the projectile.

Now the new battleship Dazhu is equipped with a 155mm heavy artillery, which can maintain supersonic flight at dozens of kilometers away, and can do huge damage even without a special warhead, but can a 30mm electromagnetic projectile fly 30 kilometers?

Assuming that the acceleration of a large-caliber sniper rifle projectile is exactly negative 200 meters per second squared, because the resistance is proportional to the speed squared, after a few seconds of flight, its acceleration will become negative 100 meters per second squared or even more Low, after the speed drops below the critical point, it will be affected by the acceleration of gravity at the end of the parabola or parabola. Finally, according to the shape, it can barely maintain the subsonic speed.

In the same atmospheric environment, what will electromagnetic projectiles of the same caliber and weight face?

As we all know, air resistance is proportional to the area facing the wind, and proportional to the square of the speed. An electromagnetic projectile of 10,000 meters per second can withstand a hundred times the resistance of a projectile of the same weight and caliber and velocity of about one kilometer per second!

Based on the above hypothetical value, the acceleration of the electromagnetic projectile at the moment of exiting the bore must be negative 20,000 meters per second squared. Because the deceleration is too fast, the actual acceleration sampling may have to be measured in 0.1 second units, which is more intuitive. Even if it flies in the first second After seven kilometers, at the starting point of the second second, the speed is only four kilometers per second. At this time, the resistance it receives is only 16% of the resistance at the time of exit. As the speed decreases, the deceleration effect will become weaker and weaker. At more than one thousand meters per second, the ballistic calculation method of conventional weapons can be connected.

In fact, hypersonic speed has to face the problem of aerodynamic heating, and the specific situation is much more complicated.

But don’t worry about it. Why do Earth Balls need electromagnetic weapons now? Is it for range?

No, for the square of the speed, the huge kinetic energy increase that can be brought about, with a small projectile, it can exert more striking force than cannonballs, and inflict effective damage on the little monsters.

From this point of view, the combat distance cannot be opened indefinitely, and within a certain distance, how many shots per minute, what is the use of electromagnetic projectiles with a caliber of only 30 millimeters? Tickle the little monster?

Why do most of the electromagnetic weapons in "Planet Strategy" are high-rate cannons, the single-barreled electromagnetic cannons of 30mm caliber are 60 or 80 rounds per minute, and the few that are not machine guns are large-caliber guns. .

As can be seen from the above example, electromagnetic weapons do not have more advantages than conventional artillery shells at long distances. Placed a hundred kilometers away, the difference between a one-ton electromagnetic projectile and a one-ton conventional warhead is almost zero because the speed difference is not too much. And within one kilometer, the electromagnetic projectile of 10,000 meters per second, even after a short deceleration, has at least dozens of times the impact force of a conventional warhead. With such a gap in impact force, it is completely fine to stuff gunpowder into the projectile. .

When using electromagnetic weapons to fight monsters, high-density delivery should be achieved within a certain distance. The so-called range of electromagnetic weapons in the game is actually to break the defense range of small monsters, not the flight range. The standards of other high-energy weapons are similar. Do you think that with the energy levels in the game, high-energy jets can't penetrate the atmosphere? If you talk about range without harm, you are playing a rogue.

All in all, in short, the electromagnetic gun sold by the same electric to the hexagonal building is a scam of money!

The Hexagon Building cannot be blamed for the matter. Although the procurement may have been affected by the lobbying company, they are also desperately rushing to the hospital.

The efficiency of country A is equivalent to the efficiency of capital operation. No matter how streamlined it is, it will take at least a few months for a purchase from the order to enter the actual battle. Anyway, if the financial market does not cut a wave of leeks, people will not deliver the product. .

And a few months later, whether country A still exists will have to be questioned. In fact, no country dares to boast in Haikou and say that it must be able to beat the second-level monster.

Under such expectations, it seems that alien knowledge cannot be transformed into combat effectiveness in the short term. Hexagon Building is eager to do things, and it is not inexcusable.

It's similar to using electricity. In the moment of life and death, you still think about cutting vegetables everywhere, and you won't be punished at all, which makes people feel cold.

But then again, today there are four first-level little monsters, and there are still qualified to consider how to deal with the second-level little monsters on the earth ball, and there are only countries that cannot be slapped.

Compared with other places, you can still cut leeks in a relatively stable environment, which is a very good treatment.

Some areas have now entered the doomsday carnival!

The most serious is the beautiful continent of Nanda.

Dameizhou and other continents are far away. The southern beautiful continent and the northern beautiful continent are connected together, separated by an artificial canal. They are basically the leek gardens in country A. Whoever dares to develop industry will cut anyone!

After decades of cutting down, those who have returned to poverty from developed countries, have not developed, can only sell resources, and can only grow "grass", all of which can be found in the beautiful continent of the South.

Because of the lack of development, Nanda Meizhou has gradually evolved into a high-profile official structure in the past few decades, with drug lords talking at the grassroots level.

Some people know that there is no hope for the future, but their survival instinct urges them to find a way out.

Rich immigrants, but rich, but the money is not very clean, immigration is not a good way.

I don’t know where the discussion started. Everyone felt that digging a refuge a few kilometers deep seemed to be able to avoid the raging monsters, and it was enough to wait for the big guys to develop interstellar technology to save people.

Don’t people in Country A often say that once a nuclear disaster occurs, their commander can wait for two hundred years in a secret base!

The big drug lords in the southern beautiful continent have also raised such high requirements. As long as they can achieve sewage treatment, underground cultivation, and establish some defenses in the external passage, and eliminate a few small monsters that have entered, they will be satisfied.

The big drug lords were busy concentrating resources and planning projects. Other street (gai) gangs and bandits found that no one was in charge. They all became excited, combined with the increasing prosperity of zero-dollar shopping, the police were too busy to touch the ground and even some people fled. , Behave more and more freely.

The basic living supplies supply system is on the verge of collapse, and mutual robbing of supplies has become a daily routine, security has been reduced to zero, and the supply of living supplies has been completely paralyzed.

It hasn't been a month since the first level-one monster appeared on the scene, and some areas have developed to the point where they dare not go out without a gun.

Every day, there are a few more corpses on the streets, and no one dared to collect them. At most, small gangs with guns fiddled with the corpses aside.

Compared with the theater in Central Central Continent, the only difference is that the artillery hasn't been fired yet.

Chaos can be contagious. When even killing people can't earn rations, some people simply use people as rations. What they can't stand is to release their targets outside and grab them elsewhere.

But if you go to other places to grab it, will you be able to grab it?

Unfortunately, the region’s agriculture is not well developed, and most of the fields are planted with “grass” that are ready to be supplied to all parts of the world... It’s too much to say that it is supplied to the whole world, and it is mainly supplied to the beautiful continent of Beijing. After all, A The two countries of China and Ca add up to a market of hundreds of billions of national currency A each year.

Fortunately, there is a banana plant ~www.wuxiaspot.com~ but the banana forest is just that, what if everyone wants to live?

In fact, the fruiting ability of bananas can still feed a lot of people, as long as everyone sits down and talks, and distributes them reasonably.

But is it possible? Why should the first come be divided among the later ones? Why should the latecomer obey the plan given by the first-comer?

Then kill each other and see who can live to the end.

In these banana forests, a life may not even be worth a banana.

From the appearance of the monster to the present, in just a few months, people in this area are degenerating into primitive tribes, except for guns in their hands.

The end of the world, but so.

Even if it is a monster crossing the border, it seems that it can hardly be worse than here.

It is a pity that things here have not attracted attention from other regions. Some are to prevent relevant news from polluting the domestic situation, and some are simply because there are too many big news in the country, and they have to tear up with neighboring countries when they are free, and simply ignore the situation in other regions.
