Chapter 2637

Liquefied magic crystal vapor is a kind of high explosive magic energy solution. It should be in gas state, but like most gases, it can be liquefied and stored after being pressurized. When liquefied magic crystal vapor is used as a weapon, it is usually projected in a liquefied state, that is, sealed in a high-pressure cylinder. When the explosive ruptures, the liquefied magic crystal vapor will quickly evaporate and change back to the gas form due to the loss of pressure. In this process, the liquefied magic crystal steam will absorb a large amount of heat, making the objects around the target instantly cool down to more than 100 degrees below zero. After that, the volatilized magic crystal vapor will quickly fill the surrounding space, and then explode like a cloud bomb in an instant The target object and the surrounding area produce a devastating strike. Because the target object is rapidly frozen before explosion, the texture tends to become brittle, and it is natural to be completely crushed under the condition of ultra-high temperature and ultra-high pressure produced by instantaneous detonation.

It is because of the above characteristics that liquefied magic crystal vapor has, it can be said that it is a very ideal explosive, and its power and killing effect are far better than those of chemical explosives under the same unit volume. However, before that, we have almost never equipped liquefied magic crystal steam shells in bulk. At most, we only equipped some special guns with a few as special ammunition.

There are only two reasons to limit the mass equipment of liquefied magic crystal steam shell. One is price, the other is activity.

Liquefied magic crystal steam is obtained by crushing, liquefying, removing impurities, and then special transformation to make it have normal temperature gas characteristics, and finally liquefied under pressure. In other words, the raw material of liquefying magic crystal steam is actually magic crystal, and magic crystal is the main energy material in the game, which is equivalent to the sum of coal and oil in reality. Such an important energy material not only has strategic significance, but also has economic value. Therefore, even if the output of magic crystal is not low, the price of this thing is still not cheap.

Combined with the above factors, we can know that the liquefied magic crystal steam is actually a very expensive material, so the economic pressure will be very large if the equipment is in batch. However, compared with the second obstacle, the first obstacle is nothing.

The biggest reason why liquefied magic crystal steam can't be equipped in batch is not the price, but the activity. The fund chain of our guild can be said to be quite solid. Moreover, because we directly control a large number of magic crystal production areas, the supply of magic crystal has always been very stable. For this reason, the impact of price on us is negligible. The real trouble is the activity of liquefied magic crystal steam.

The stability of liquid magic crystal steam has always been very bad. In and out of the game, the only thing I have seen that is more unstable than liquefied magic crystal steam is nitroglycerin. Only a slight vibration or squeeze, sometimes even a sudden change in temperature of a few degrees, liquefying magic crystal vapor will suddenly explode without warning. It can be said that this thing is a kind of time bomb, no one knows when it will suddenly explode.

Of course, the above characteristics are the basic characteristics of liquefied magic crystal steam. Since our guild can use it, it naturally has a treatment method. First of all, our technicians found an antiknock, which can effectively inhibit the activity of liquefied magic crystal steam. Although this kind of antiknock can reduce the explosive force of liquefied magic crystal vapor by one or two percentage points, it is still very valuable considering the substantial improvement of safety. Moreover, at present, as soon as the liquefied magic crystal steam of our guild is produced, this kind of antiknock will be added, and this regulation has been proved to be effective in reducing the explosion accident rate of liquefied magic crystal steam in our guild.

After adding this kind of antiknock agent, the activity of liquefied magic crystal steam will decrease slightly, so the safety of liquefied magic crystal steam can be ensured in the general transportation and storage process. As long as the operation is carried out according to the safety regulations, there is no need to worry about explosion. However, this is only the safety and stability in the process of transportation and storage, but it is totally different in use.

The liquefied magic crystal steam in the storage state is static. As long as the temperature change is well controlled, there will be no danger. In addition to the temperature bumping during transportation, squeezing, impact and vibration will occur. However, because we have used a series of methods to reduce or eliminate the occurrence and degree of these situations, the liquefied magic crystal steam will still be It is stabilized in a safe state and will not explode.

Although transportation and storage can ensure a safe state, but the use of the process is completely different. Our liquefied magic crystal vapor explosive has not been equipped in large scale before. Although we started to equip in batch, we only used two types of liquefied magic crystal Vapor Bomb, one of which is the throwing bomb and the other is the rocket type.

The types of drop bombs include aerial bombs and hand grenades. These are all throwing bombs. They do not have the ability to fly. They are either dropped from a high place or thrown at a short distance. Both of them have the same characteristics, that is, no matter which way, they will vibrate only when they finally hit the target. Before that, they are all relative Stable state, so there's no need to worry about explosions.

The rocket like liquid magic crystal Vapor Bomb is relatively dangerous, but the situation is not so exaggerated as expected. First of all, the liquified magic crystal steam rocket used by our guild is actually very small. Among them, the most popular one is the kind of liquefied magic crystal steam missile which is the size of a pen and has a magic array of guide arrows for mobile angels. In fact, the volume of the liquefied magic crystal steam missile is very small, so the quality of the internal charge is relatively small, so the anti-seismic ability is greatly enhanced, and it is easy to avoid explosion. In addition, rocket boost is not the same as cannon fire. The acceleration process of the rocket is a smooth curve, and its acceleration time is very long, but the speed in the initial period of acceleration is not fast. This is why we dare to produce liquefied magic crystal steam missile but dare not produce liquefied magic crystal steam shell.Liquefied magic crystal steam shell, as the name implies, is a shell with liquefied magic crystal steam. Then, as a kind of shell, it must be fired by cannon, and the principle of cannon firing is to produce high-pressure gas which can rapidly expand by reaction of certain chemical substances, so as to push the shell out of the barrel. This acceleration process is very short, and the acceleration is terrible. Unlike the slow speed of the initial stage of the rocket, and then the speed is faster and faster, the shell is in the initial stage of occurrence, which is instantaneous to reach the limit speed, and the process is often only a few seconds. In such a short period of time to accelerate to several times the speed of sound, you can imagine how strong the vibration will be in the process. Therefore, even with the addition of antiknock agent, the explosion rate of liquefied magic crystal steam is almost 100%.

Although we had previously equipped certain artillery with liquid magic crystal steam shell, it was actually a kind of fake shell. That kind of shell is not so much a shell as a rocket from the barrel. It is actually a kind of rocket rather than a real cannon.

It is because there are so many problems in the production of liquefied magic crystal steam cannons that I am surprised that the battleship Christina is equipped with liquefied magic crystal steam shells as standard, which is a bit frightening.

"Did you actually use the liquid magic crystal steam shell? How do you do it? Can't you blow it up? " After hearing Sophie's answer, even Kristina on one side was surprised. Although she is only a mage rather than a magic technology researcher, we guild players basically know some of the basic characteristics of liquefied magic crystal steam. After all, this thing should be attached to the first-line personnel, so everyone should understand the characteristics of this thing to avoid improper operation To make a mistake.

Sophie explained to me as she led us to the second turret ahead: "this problem is solved in many ways. The first point is that our guns are not propelled by gunpowder, but use the magic version of the electromagnetic coil propulsion principle. Therefore, the occurrence process of this kind of cannon is milder than that of the past guns. Although the muzzle speed of the cannons is one third faster than that of the old guns, the peak acceleration is only one fifth lower than that of the old guns When the gun is launched, the extrusion effect on the internal liquefied magic crystal steam is lower

I nodded and said, "but even so, the liquid magic crystal steam will still explode?"

"Of course, we can not rely on this feature alone to prevent the explosion of liquefied magic crystal steam in the barrel. The electromagnetic cannons only reduce the pressure so much that we can find solutions in other directions. "

"How did you solve it?"

"Our solution is actually very simple. The first is to stop using integrated charges. "

"No integrated charge?" After a little hesitation, I suddenly thought of the reason. "Oh, I see. Liquefied magic crystal vapor is not gunpowder, its explosion effect is similar to cloud explosive bomb, so there is no need for shaped charge technology. Instead, the structure similar to cluster bomb can be used to disperse all the explosives originally concentrated in one cabin into several different containers. In this way, the quality of liquefied magic crystal steam in a single container is lower, and the anti explosion ability will be much better. "

In fact, the principle I'm talking about is very simple. To put it bluntly, an object with a small mass has a lower inertial kinetic energy at the same speed. For example. If there is a row of passengers in two cars running side by side, the speed of the two cars is the same. One of the cars had 100 passengers and the other had only 10 passengers. The passengers in both cars stand in a straight line along the axis of the car body. The front one has a baffle in front of it. If two cars suddenly hit an obstacle at the same time, the passengers in the car must slide forward. In the car with 100 passengers, the person standing in the front of the car will not slide forward because of the baffle. However, if the 99 people behind him want to stop their inertia, they need to transfer all their kinetic energy to the person in front of him. The kinetic energy of 100 people will be concentrated, and the final result is that the person in front looks like a rotten West It burst like a melon. On the contrary, although the situation in the next car is similar, the person in the front only needs to bear the kinetic energy of ten people, so he is only fracture at most, and the survival coefficient is much higher than that of the first person in the next car.

The same is true. If a large container is filled with liquefied magic crystal steam, when the container suddenly accelerates, the pressure of the liquefied magic crystal steam at the end of the container will be much higher than that of the last part of the liquefied magic crystal steam in a small container. Therefore, the larger the container is, the worse the explosion resistance of the liquefied magic crystal steam storage tank will be, otherwise it will be In order to improve the explosion resistance.

Of course, the antiknock capacity is not proportional to the volume of the container, but changes according to a certain curve. When the volume is lower than a certain critical point, the effect of reducing the volume is actually very small. Therefore, the vessels used in this kind of liquefied magic crystal steam shell should be in the best proportion. They can fully disperse the pressure, ensure the safety of liquefied magic crystal steam, and reduce the number of charging units. After all, the more complex the structure, the more difficult the production.

Seeing that I understood the principle, Sophie continued to explain: "besides the dispersed charge, the internal shape of the container can also affect the stability of the liquefied magic crystal steam. Now the liquefied magic crystal steam vessels in this kind of liquefied magic crystal steam shell are all cone-shaped, and the tip of the cone points to the warhead. If you open the fairing on the outside of the warhead, you can see that there are liquefied magic crystal vapor containers arranged inside like sub warheads. In fact, those containers are not sub warheads at all, but because this shape is conducive to resisting the acceleration of launching. ""Can the liquefied magic crystal steam shell be used safely only by virtue of its own characteristics and by changing the charge form?" Asked Christina.

"Of course, it's more than that. In addition to what I just said, there are other designs, such as the ability to stabilize positions. This is a magic array, which is carved on the outer walls of all liquefied magic crystal steam containers, which can ensure the further stabilization of liquefied magic crystal steam. However, this magic array will reduce the explosion power of liquefied magic crystal steam. Therefore, we have installed a pre explosion device outside the container. This thing will detonate 0.001 seconds in advance of the shell, destroying the magic array, and then liquefying the magic crystal steam will explode. In this way, the liquefied magic crystal steam in the shell can be stabilized without reducing the power of the shell. "

"It's not just about the technology, is it?"

"That's the main technology. In addition, there are some small stable technologies, but they are all double insurance and so on. There is no big difference between them. It's just a psychological comfort. According to the design of this kind of gun, the possibility of this kind of explosion is far lower than that of the gun group

In fact, what many people don't know is that the electromagnetic railgun has a feature, that is, the shell and the barrel will not contact during the launching process. When a gun is launched, it is necessary to use the propulsion gas to send the shell out, so the projectile and the barrel need to fit together as much as possible, just like the cylinder in the engine. If the projectile is too small, the gas generated by the gunpowder explosion will leak out around the shell, and the propulsion force will be greatly reduced. This is also the reason why guns in the past were particularly easy to explode. Because the barrel and the projectile were too close to each other, the barrel would inevitably deform due to abrasion and other reasons during the launching process. Once the barrel was deformed and the projectile was stuck, then even if the projectile itself did not explode, the propellant would be enough to burst the barrel.

In contrast to artillery, the electromagnetic gun uses a magnetic field to propel the projectile, so there is no need to seal it at all. Although the electromagnetic force will decay with the increase of the distance, there will not be too large gap between the barrel and the projectile, but after all, it is not necessary to be air tight. Moreover, the powerful electromagnetic repulsion force will force the projectile to be always suspended on the central axis of the barrel. Therefore, as long as the deformation of the barrel is not too severe, there will be no problem basically. In addition, the barrel deformation of artillery is mostly caused by wear caused by excessive firing times, or deformation caused by high temperature caused by continuous firing in a short period of time. However, there is no friction at all in the electromagnetic gun, so there is no way to talk about wear. As for high temperature Although the instantaneous temperature of the electromagnetic coil may exceed the temperature of the gunpowder, this temperature will only occur within 0.001 second. The actual heat generated is not large, so it will not cause any deformation of the gun barrel. Moreover, because the barrel does not need to bear the expanding tension caused by the explosion of propellants, the barrel of electromagnetic railgun does not need to use high hardness steel at all. As long as a support frame is used, the rest can be made of refractory materials. In fact, because metals shield electromagnetic fields, the barrel is destined to use only nonmetallic materials. At least the inner wall of the barrel should not be made of metal.

While Sophie was explaining how to use the liquid magic crystal steam cannon, most of the boys had climbed up to the top of turret two. In order not to be blocked by the No. 1 turret, there is a base more than two meters high under the No. 2 turret. In this way, the No. 2 turret will be more than 2 meters higher than the No. 1 turret, so as to make the front firing range for the No. 2 turret. In fact, there is a turret 3 behind us, which is directly placed on the top of the front building of the warship Island Bridge, which is more than three meters higher than the second turret. The three turrets placed at random can ensure the forward firepower of the warship, and also make the overall structure of the warship more coordinated.

After climbing up to the base of the turret, the other boys pulled the door handle on the side of the turret, but tried without pulling. These doors are high-pressure doors, which use self tightening technology. If you don't care about them, the doors will close automatically, and then the pressure handle will gradually lock itself to the most tight state.

Children don't know about this design, but a few impatient kids are already knocking on the door. With their knock on the door, the handle on the inverted gate immediately turned itself, and then the door opened and a head came out.

"What's the matter?" It's a NPC coming out of it. There is no precedent of using all players to fight on the warships of our guild. There are only a few players on all warships to command, most of them are NPC, and the Kristina is no exception.

The children outside knocked at the door just because they were excited to see what was going on inside. But someone really opened the door and was at a loss. Fortunately, I was down there. After seeing the NPC, I waved directly to him to let go. The other party immediately came out and stood by the door and opened the door. The children around this time is not reckless, but first salute each other, said a thank you, then rushed to the inside.

"Shall we go up and have a look?" Sophie asked.

I nodded and went straight up the ladder. In fact, there is an internal passage for this fort, but since we came up from the deck, we have to go up from the vertical ladder outside.When they got on the base and walked to the gate, the children and the commander's aunt had already entered the turret. Although there were more than 40 people, they all got into the turret because it was really huge.

When we got to the door, I found that the gate of the turret was not one door, but three. Just when the children knocked on the door, I estimated that the inside door should not be closed, or there should be no outside knocking at all.

The outermost door at the entrance of the turret is an all metal door that opens outwards. The thickness is about 3cm, which can be said to be very strong. Of course, considering the power of warship guns used in various large-scale guilds, the steel plate of this thickness is not very different from the window paper. However, the door was not bullet proof, so it was not too thin.

Behind this first door is the real armored door, which is a retractable gate embedded in the wall, with a thickness of at least 60 cm. There is a third door behind the door, which is also open and closed, but it opens inward. The thickness of the door is close to 50cm, but it is not made of steel. Obviously, one third of the door is soft material. Its main function is sound absorption and noise reduction.

Although the thickness of the three gates is more than one meter, the three doors are not tightly connected, because the entrance of the turret is not a simple wall, but a passage more than three meters long. That is to say, the outer wall of the turret is more than three meters thick. Of course, this thickness is not all armor plate, but when it can reach this thickness, at least two meters of which are made of steel plate, which is really a blockhouse.

Although the outer wall of the turret is very thick, greatly reducing the internal space, but because the turret itself is very large, the internal environment is also different from what was imagined. In fact, the space inside the turret is not as narrow as expected. More than 40 people are just standing full, and they don't even feel crowded.

The space inside the turret is not a regular rectangle, but a concave shape. The missing space in the center is occupied by a huge device connecting the floor to the ceiling. I know this thing, but Sophie next to me still took the initiative to introduce: "the huge central thing is the automatic loader. There is a loading port for the two guns on the left and right of the turret, but because the two loaders are packed back to back, they look like a whole

"Big sister, what is the caliber and firing speed of this cannon?" A child asked excitedly.

Sophie immediately laughed and said, "are you good at it. In fact, there is no caliber for these two guns, because they are electromagnetic cannons made by using the thunder magic array. Therefore, as long as the shells that can be inserted into the barrel can be fired normally no matter what caliber you have, this is the advantage of electromagnetic guns. However, the diameter of our gun barrel is only 1.65 meters, so the maximum diameter of the shell that can bear should be only 1.64 meters. After all, if the projectile is too large, it will collide with the magic array inside. Therefore, the shot to be fired should be one centimeter smaller than the barrel, so that the magic array inside the barrel will not be rubbed. As for the speed of fire The advantage of this cannon is not the speed of fire, so it's not very fast. At most, it's eight to ten rounds per minute

Although this speed is really slow compared with those machine guns which can shoot dozens of bullets per second, Sophie's words are obviously too modest. You know, this is not a submachine gun. This is a naval gun, and it's the front main gun. Does this thing take hundreds or thousands of shots a minute? Again. Even with that rate of fire, with the caliber of this cannon, how big is the ammunition depot to keep up with its consumption? After all, the volume of large caliber shells is not small. Every shell launched by this device weighs several tons. Even if Christina is large, it is impossible to carry too many shells for the main gun, right?

The children didn't quite understand what an electromagnetic gun was, but they were excited to follow Sophie and ask for something else. One of the children probably knew what the electromagnetic gun was, so he seriously asked, "big sister, what is the range of this electromagnetic gun? It's said that the range of electromagnetic guns is very long. "

When Sophie heard the other party's question, she immediately said: "if you don't specify a target and let me shoot at will, this gun can shoot shells to a place 1000 kilometers away, but unfortunately, the actual use distance of this thing is only 200 kilometers."

"Why?"

"Because the enemy is too far away, we can't see it!"

Sophie's answer was simple, but the children didn't understand, but I understood. The flying speed of the electromagnetic gun is very fast, so the range will be increased correspondingly. But the problem is that there is no self guided projectile technology in the game, and the magic array of guided arrows also needs to be able to see the target to play a role. Therefore, even if we can use the pilot ship to investigate in front, we can't guide the artillery to hit the target at such a distance. In addition, there is another problem that affects the range of the electromagnetic gun, that is, its trajectory.

The muzzle velocity of the electromagnetic gun is too high, so its trajectory is very straight. Although it is impossible for any solid ammunition to fly out of a straight line on earth, this line will be very close to the straight line. It's OK to say if the range is short, but the problem comes when the range is long. Because the earth is round, if the target is too far away, it will be blocked by the raised sea level. If the trajectory is curved, it can be launched. However, the problem is that the trajectory of the electromagnetic gun is almost straight, so it can not be launched. The result is that the target is blocked behind the horizon, and the naval gun has no firing angle at all. Of course, although the reason for the pain has limited the range of our artillery, we have to say that it is still the longest range artillery known. After all, without considering the trajectory, it can hit 1000 kilometers. This range can only be described as insane.Sophie began to lose credibility after a few words of explanation, but there were NPC on this side. So Sophie, the captain, directly handed the work of the commentator to several turret operators on the spot, and then she was free.

As she ran out to breathe, I asked, "has this ship been tested yet?"

Sophie stood on the edge of the base outside the turret, with her back against the safety railings, and said, "all the ships of the leader class Oh, I forgot. All of these battleships belonged to the chieftain class, and Christina was just one of them. Basically, our warships have not been tested. It seems that the technical red moon has tested the basic properties of short-range rapid acceleration. That battleship Eagle has tested the floating system, but all the guns of the warship have been tested in the test field, and they have not been tested on board the warship. "

"Don't you test it?" Asked Christina.

"This is the first voyage of the Christina, and it is also a test voyage. According to the original plan, we will deliberately find several islands at sea to test the weapon power and range, and we will also test the power system during the voyage. After entering the sea area where there are few ships, it will be decided whether to test the floating system or not according to the situation. "

"And test the floating system?" Christina asked in surprise, "but there are outsiders on the warship now."

Before Sophie could answer, she said, "it's not a problem. Just bring those kids in the boat in the name of a visit. As long as you can't see the sea, who knows whether the ship is sailing on the sea or flying in the sky

"That's what I said." Christina nodded. "Oh, by the way, I'll go to the bridge and pilot my own warship. Is that ok?"

"Of course." Sophie said with a smile, "anyway, the sea is wide enough. You can't rush to the shore even if you are stupid."

"Are there any reefs?"

"Do you think I'll let you sail in the sea with reefs?"

"That's true

As we were talking, we saw the children coming out of the turret one after another. These children are very excited now, because they have just heard that the NPC inside has said that they will test artillery during the voyage, so they surround me as soon as they come out and ask if they can watch the artillery test firing.

In addition to the flight system, other things of this warship are not classified, so I did not refuse and agreed to come down. "I'll tell you first. It's OK to see, but you must listen to the command and watch through the observation window inside the bridge."

"Why?" Asked a child, slightly disappointed.

"Because the detonating moment the shell comes out of the chamber is enough to blow you all away." Replied Christina. Although this is an electromagnetic gun, there is no muzzle flame and so on, so it is not as shocking as the gunpowder naval gun in the past, but after all, this thing needs to radiate out a shell with several tons of weight by several times the sound speed, so the shock wave is still quite terrible. Although this shock wave will not hurt players like us, most of these children are not high-level, and their own attributes are very bad. Most of them can't resist these shock waves with their defense power. Death is not likely, but being blown into the sea is also a trouble, isn't it?

Because I explained it reasonably, the children didn't make much noise. After that, on my suggestion, they gave up following us. Instead, they started to visit the warship with several NPCs from Sophie. The boat is nearly 1000 meters long, and the interior is like a small city. It is enough for them to play in it, so I've got rid of these energetic little guys for a while.

When it was quiet, I went to the bridge with Sophie, and the ship was slowly backing out of the harbor. Half of the ships that had been parked side by side with Christina had gone out before Christina left, and the remaining half immediately followed us as we moved.

As the largest warship here, the Christina is, of course, the flagship of the fleet. After leaving the port, Christina turned south, while the other warships quickly moved around the Christina to form a cruising fleet and began to sail with her.

"When do we start testing?" Now that I'm on board, I'd like to see the test results of this ship. Although I may not have the opportunity to see the situation of several other leader class battleships, with the data of this Kristina, I can at least find a suitable target if there is anything that needs fleet support in the future, isn't it?

After hearing my question, Sophie didn't answer it immediately. Instead, she looked at the chart and said, "in about 20 minutes, we'll be able to reach a group of islands. There are no man-made islands over there. We can find a mountain to test. But before that, we can test the navigation system. "

"What kind of test do you mean by rapid acceleration and extreme deceleration?" Asked Christina, somewhat worried.

Sophie looked at Christina in surprise and asked, "what are you doing with that look?""I never said that. I'm a little bit seasick," Christina said, sheepishly

"In the game?" Sophie and I were surprised this time.

Christina shrugged. "I know it's rare, but I'm seasick and I can't help it. It's fine if you sail normally, but I can't stand it if you do stunts at sea
