Liquefied magic crystal steam is a kind of high explosive magic energy solution. It should be gaseous, but like most gases, it can be liquefied and stored after being pressurized. When liquefied magic crystal vapors are used as weapons, they are generally projected in a liquefied state, that is, sealed in high-pressure steel cylinders. When the explosive ruptures, due to the loss of pressure, the liquefied magic crystal vapor will quickly evaporate and change back to the gas form. During this process, the liquefied magic crystal vapor will absorb a large amount of heat, which will instantly cool the surrounding objects to more than minus 100 After that, the vapor of the magic crystal that volatilizes will quickly fill the surrounding space, and then a detonation similar to a cloud detonation bomb will occur instantly, causing a devastating blow to the target object and the surrounding area. Because the target object was rapidly frozen before the explosion, the texture tends to become brittle, and it is a matter of course that it is completely crushed under the conditions of ultra-high temperature and ultra-high pressure generated by instant detonation.
Because the liquefied magic crystal steam has the above characteristics, it can be said that this is a very ideal explosive. Under the same unit volume, its power and killing effect are far superior to chemical explosives. However, before that, we almost never equipped the Liquefied Magic Crystal Steam Cannonball in batches, and at most only equipped a few rounds for some special artillery as special ammunition.
There are only two reasons for limiting the batch equipment of Liquefied Magic Crystal Steam Cannonballs. One is price and the other is activity.
The liquefied magic crystal steam is obtained by crushing the magic crystal, liquefying it, removing impurities, and then performing special transformation to make it possess normal-temperature gaseous characteristics, and finally pressurizing and liquefying. In other words, the raw material of liquefied magic crystal steam is actually magic crystal. The magic stone 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 is not only of strategic significance but also of economic value. Therefore, even if the output of magic crystal is not low, the price of this thing is still not cheap.
Combining the above factors, we can know that the liquefied magic crystal steam is actually a relatively expensive substance, so the economic pressure will be very large if it is batch-equipped. However, the first obstacle is actually nothing compared to the second obstacle.
The biggest reason that LPG steam cannot be equipped in batches is not price but activity. The bank's funding chain can be said to be quite solid. And because we directly control a large number of magic crystal producing areas, the supply of magic crystal in our bank has always been very stable. For this reason, the price factor has little effect on us. The real trouble is the activity of the liquefied magic crystal steam.
The stability of Liquefied Magic Crystal Steam has been very poor, both inside and outside the game. The only thing I've seen that is more unstable than liquefied magic crystal steam is nitroglycerin. Only slight vibration or squeezing is required. Sometimes it's just a few degrees when the temperature suddenly changes. The liquefied magic crystal vapor will suddenly explode without warning. It can be said that this thing is simply an irregular bomb, and no one knows when it suddenly exploded.
Of course, the above characteristics are the basic characteristics of liquefied magic crystal steam. Since our guild can be used, there is naturally a way to deal with it. First, our technicians found an anti-knock agent that can effectively inhibit the activity of liquefied magic crystal steam. Although this anti-knock agent will cause the explosive power of the liquefied magic crystal vapor to drop by one or two percentage points, considering the greatly improved safety, this stuff is still very valuable. Moreover, at present, as long as the liquefied magic crystal steam of our guild is produced, this anti-knock agent will be added, and this regulation has been proven to effectively reduce the incidence of liquefied magic crystal steam explosion accidents in our guild.
After the addition of this anti-knock agent, the activity of the liquefied magic crystal vapor will be slightly reduced, so that the safety of the liquefied magic crystal vapor can be guaranteed during general transportation and storage. As long as you operate in accordance with safety regulations, you do not need to worry about explosion. However, this is just a matter of safety and stability during transportation and storage, but it is completely different in use.
The liquefied magic crystal vapor in storage state is static. As long as the temperature change is controlled, there will be no danger. In addition to the temperature during transportation, it will cause squeezing, impact and vibration due to bumps, but because we use a The series of methods reduce or eliminate the occurrence and extent of these situations, so basically the liquefied magic crystal vapor will still be stabilized in a safe state, and there will be no explosion due to this.
Although transportation and storage can guarantee a safe state, it is completely different during use. Our liquefied magic crystal steam explosives had not been equipped on a large scale before. Although they began to be equipped in batches, only two types of liquefied magic crystal steam bombs were actually used, one of which was a drop bomb and the other This type is rocket type.
The types of drop bombs include aerial bombs and grenades. These are considered to be drop types. They do not have the ability to fly. They are either thrown from a high place or thrown over a short distance. Both methods have common characteristics. That is to say, no matter what kind, it will only tremble when it hits the target at the end. Before that, it was in a relatively stable state, so there is no need to worry about the explosion.
Rocket-type liquefied magic crystal steam bombs are relatively dangerous, but the situation is not as exaggerated as expected. First of all, the liquefied magic crystal steam rockets used by our guilds are actually very small. The most produced models are the pen-sized liquefied magic crystal steam missiles equipped with guided arrow magic arrays for mobile angels. The volume of this liquefied magic crystal steam missile is actually very small, so the quality of the internal charge is relatively small, which has greatly strengthened the seismic resistance and will not easily explode. In addition, rocket boost is different from artillery firing. The acceleration process of the rocket is a smooth curve, and its acceleration time is very long, but the speed is not fast in the early stage of acceleration. This is why we dare to produce liquefied magic crystal steam missiles but dare not produce liquefied magic crystal steam cannonballs.
Liquefied magic crystal steam cannonballs, as the name implies, are shells filled with liquefied magic crystal steam. Well, as a shell. It must be fired with a cannon. The firing principle of the cannon is to react with a certain chemical substance to generate a high-pressure gas that can expand rapidly, thereby pushing the shell out of the barrel. This acceleration process is very short, and the acceleration is extremely scary. Unlike the slow speed of the rocket at the beginning, and the faster and faster speed afterwards, the shells reach the speed limit in an instant in the initial stage of the occurrence, and this process is often only a few tenths of a second. Accelerating to several times the speed of sound in such a short period of time, you can imagine how strong the vibrations in this process will be. Therefore, even with the addition of anti-knock agents, the shot of liquefied magic crystal steam is almost 100% of the bomb chamber.
We had previously equipped some specific guns with liquefied magic crystal steam cannonballs. But it was actually a pseudo-shell. That kind of shell is not so much a shell. It is better to say that the rocket occurred from the barrel, but it is actually a rocket rather than a real cannon.
It is precisely because there are so many troubles in the production of liquefied magic crystal steam cannons that I would be surprised that this battleship of Kristina is actually equipped with liquefied magic crystal steam cannons. This is too scary.
"Surely I used the Liquefied Magic Crystal Steam Cannonball? How did I do that? Wouldn't it blow up the chamber?" Even Kristina, who was on the side, was surprised when she heard Sophie's answer. Although she is just a mage and not a magic technology researcher. But the basic characteristics of the liquefied magic crystal steam, our guild players basically know some. After all, this stuff must be assigned to front-line personnel in the end, so everyone must understand the characteristics of this thing, so as to avoid accidental injury caused by improper operation.
Sophie explained to me as he took us to the second turret in front: "This problem is solved in many ways. The first point is because our artillery is not propelled by gunpowder. It uses a magic version of electromagnetic The coil propulsion principle, so the process of this type of artillery is more gentle than the past artillery. Although the speed of the artillery shell is one third faster than that of the old artillery, the peak acceleration is only five times that of the old artillery. The first is even lower, which means that this kind of artillery has a lower squeeze effect on the internal liquefied magic crystal steam when it is launched. "
I nodded and said, "But even if the liquefied magic crystal steam will still burst?"
"Of course, this feature alone cannot be used to prevent the explosion of the liquefied magic crystal vapor in the barrel. The electromagnetic cannon has only greatly reduced the pressure, so that we can find a solution from other directions."
"Then how did you solve it?"
"Our solution is actually very simple. The first is to stop using integrated charging."
"No need for integrated charging?" I hesitated a little and suddenly thought of the reason. "Oh, I see. Liquefied magic crystal steam is not gunpowder. Its explosive effect is similar to cloud explosion bombs, so it does not require concentrated charge technology. Instead, it can use a structure similar to a cluster bomb to concentrate the original in a cabin. The explosives in it are all dispersed into multiple different containers, so the quality of the liquefied magic crystal vapor in a single container is lower, and the explosion resistance will be much better. "
The principle I am talking about is actually very simple. To put it bluntly, a small-mass object has a lower inertial kinetic energy at the same speed. For example. If there is a row of passengers in two cars driving side by side, the speed of both cars is the same. One of them had a hundred passengers and the other had only ten passengers. The passengers in both cars stand in a straight line along the axis of the vehicle body, and the frontmost person has a baffle in front of them. Suppose the two cars suddenly hit an obstacle at the same time. At this time, the passengers in the car must all slide forward. In the car with one hundred passengers, the person standing in front was blocked by the baffle, so he would not slide forward, but the ninety-nine people behind him needed to stop the forward inertia, The kinetic energy of all of them was transferred to the person in front, and the kinetic energy of one hundred people was concentrated together. The end result was that the person in front burst suddenly like a rotten watermelon. On the contrary, although the situation in the next car is similar, but the frontmost person only needs to bear the kinetic energy of ten people, so he only has a fracture at most. The survival coefficient is definitely higher than that of the first person in the next car. Much higher.
Same thing. If a large container is filled with liquefied magic crystal steam, when the container suddenly accelerates, the pressure of the part of the liquefied magic crystal steam at the tail of the container will be much higher than the last part of a small container liquefaction. The pressure on the magic crystal steam. Therefore, the larger the container, the worse the explosion resistance of the liquefied magic crystal steam storage tank. Conversely, the explosion resistance can be improved.
Of course, the size of this anti-explosion capacity does not increase or decrease in proportion 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 minimal. . Therefore, the containers used in such liquefied magic crystal steam cannons should be based on an optimal ratio. They can fully disperse the pressure, ensure the safety of the liquefied magic crystal steam, and also reduce the number of charging units. The more difficult the complex production is.
Seeing that I understood the principle, Sophie continued to explain: "Beyond the dispersion charge. The internal shape of the container can actually affect the stability of the liquefied magic crystal steam. Now the liquefied magic in the liquefied magic crystal steam cannonball. The crystal steam container is actually all conical. The tip of the cone points to the direction of the warhead. If you open the fairing outside the warhead, you can see the liquefied magic crystal steam container arranged inside like a warhead. In fact, those are not at all. The warhead is because this shape is good for combating acceleration during launch. "
"Just relying on the characteristics of the electromagnetic cannon and changing a charge form, can the liquefied magic crystal steam cannon be used safely?" Kristina asked.
"Of course, there is more than this improvement. In addition to those I just said. There are some other designs. For example, the magic can stabilize the position. This is a magic array. It is carved on the outer wall of all liquefied magic crystal steam containers. Above, it can ensure the further stabilization of the liquefied magic crystal steam, but this magic array will reduce the explosive power of the liquefied magic crystal steam. So we also installed a pre-explosion device outside the container. This thing will be in front of the shell Detonate at 0.101 ahead of time, destroy the magic array, and then the liquefied magic crystal steam will explode, so that the liquefied magic crystal steam in the shell can be stabilized without reducing the power of the shell. "
"There should be more than that, isn't it?"
"That ’s the main technology. In addition, there are some small stabilization technologies, but they are all double insurance. There is not much difference, just a psychological comfort. According to the designer of this gun group, this kind of The use of liquefied magic crystal steam cannons with such electromagnetic cannons has a much lower possibility of bombing than previous artillery, so it has fully met the needs of actual combat. "
In fact, what many people don't know is that the electromagnetic rail gun has a characteristic that the projectile and the barrel will not contact each other during the launch process. When the artillery is launched, the projectile needs to be sent out with the propellant gas, so the projectile and the barrel need to fit as closely as possible, just like the cylinder in the engine. If the projectile is too small, the gas generated by the gunpowder explosion will be from the surrounding area of the shell. Leaked out, so the propulsion will be greatly reduced. This is why the past artillery was particularly easy to blast, because the barrel and the projectile are in close contact, and the barrel is inevitably deformed due to wear and tear during the firing process. Once the barrel is deformed, the projectile is stuck. The projectile itself did not explode, and the propellant was sufficient to explode the barrel.
In contrast to artillery, electromagnetic guns use magnetic fields to propel the projectiles, and they do not need to be sealed at all. Although the electromagnetic force will attenuate with distance, the gap between the gun barrel and the projectile will generally not be too large, but after all, it is not necessary to be airtight, and the strong electromagnetic repulsive force will force the projectile to remain suspended in the gun barrel. On the central axis, as long as the barrel deformation is not serious, basically there will be no problems. Besides, the barrel deformation of the artillery is mostly due to wear caused by excessive firing times, or deformation caused by high temperatures caused by continuous firing in a short period of time. However, the electromagnetic gun has no friction at all, so it is impossible to talk about wear and tear. As for the high temperature and so on ... this is true, but it is far from the temperature of the artillery. Although the instantaneous temperature of the electromagnetic coil may exceed the temperature of the gunpowder, this temperature will only occur within 0.011 seconds, which actually occurs. In fact, the heat is not large, so it will not cause deformation of the barrel at all. Moreover, because the barrel does not need to withstand the expansion force generated when the propellant explodes, the barrel of the electromagnetic railgun actually does not need to use high hardness steel at all. As long as a support frame is used, the remaining part can be completely made of refractory material. Production. In fact, because metal shields the electromagnetic field, the barrel is destined to use only non-metallic materials. At least the inner wall of the barrel must not be made of metal.
Just as Sophie explained to us how this liquefied magic crystal steam cannonball was used, most of the boys had already climbed onto the second turret. In order not to be blocked by the No. 1 turret in front of the firing range, there is a base more than two meters high under the No. 2 turret. In this way, the turret number two will be more than two meters higher than the turret number one, thus giving way for the turret number two to exit the front. In fact, there is a third turret behind us, which is placed directly on top of the front building of the battleship Island Bridge, which is more than three meters higher than the second turret. The three turrets placed in this way can ensure the frontal firepower of the warship, and at the same time, the overall structure of the warship can be more coordinated.
After the children climbed to the base of the turret, a few of them went to pull the door handle on the side of the turret, but tried a few times without pulling. These doors are high-voltage doors that use self-tightening technology. If you don't care about it, the door will automatically close, and then the pressure handle will gradually lock itself to the tightest state.
Children do not know about this design. But a few irritable children are already knocking at the door. With their knocks. The handle on the inverted gate immediately spun on itself, then the door opened outward, and a head stuck out.
"What's the matter?" One who came out of it. There are no precedents for using all players on the battleships in this guild, and there are only a few players on all the ships. Most of them are. This Christina is certainly no exception.
The children outside just wanted to see what was going on inside. That's why I knocked on the door, but someone really opened it and was at a loss, but fortunately I was below. After seeing that, I waved directly at him for release. The other party immediately came out and stood by the door, pulling the door open. The surrounding children were not reckless this time, but they saluted to the other party first and thanked them before running happily.
"Let's go up and see, too?" Sophie asked.
I nodded and climbed up the ladder. In fact, this turret has internal passages, but because we came up from the deck, we had to go up from the vertical ladder outside.
After boarding the pedestal and walking to the gate, the children and the head aunt had already entered the turret. Although there were more than forty people, because the turret was really huge, they all got into it.
When we came to the door, I realized that the door of this turret was not actually a door, but three. When the children knocked on the door just now, I guess the door on the inside should not be closed, otherwise the knock on the outside should not be heard at all.
The outermost door at the entrance of this turret is an all-metal door that opens outwards. It is about three centimeters thick and can be said to be very strong. Of course, considering the power of warship guns used by large guilds today, Steel plate is not much different from window paper. But this door wasn't originally designed to be bulletproof, so it's not a big problem to be thin.
Behind this first door is the real armored door. This door is a telescopic gate embedded in the wall, which is at least sixty centimeters thick. There is a third door behind this door. This door is also open and closed, but it opens inward. The thickness of this door is close to fifty centimeters, but it is not all-steel. Obviously one third of the interior is soft material. Its main function is probably sound absorption and noise reduction.
Although the thickness of the three doors is more than one meter, the three doors are not tightly connected, because the entrance of the turret is not just a wall, but a passage more than three meters long. . In other words, the outer wall of this turret is actually more than three meters thick. Of course, this thickness is not all armor plates, but it can reach this thickness, at least two meters of which are steel plates. This defense is really a bunker.
Although the outer wall of the turret is thick, it greatly reduces the internal space, but because the turret itself is very large, the internal environment is also different from what was expected. The space inside this turret is actually far from the narrowness of imagination. When more than forty people are crowded in, they are just full, and they don't even feel crowded.
The space inside the turret is not a regular rectangle, but a concave shape. The missing part of the center is filled by a huge device that connects from the floor to the ceiling. I know this thing, but the next Sophie still actively introduced: "The huge thing in the center is the autoloader. The left and right guns of this turret each have a loading port, but because of the two loading machines Back to back squeezed together so it looks like a whole. "
"Sister, what's the caliber and firing speed of this cannon?" A child asked in excitement.
Sophie immediately smiled and said, "Are you quite sensible? The two guns are actually not caliber one, because they are electromagnetic cannons made using the Thunder magic array. So as long as they can be inserted into the barrel of the gun, No matter what caliber you can fire normally, this is the advantage of electromagnetic guns. However, the diameter of our barrel is only one meter six five, so the maximum diameter of the shell that can be carried is only one meter six four. After all, the projectile is too large. Collided with the magic array inside, so the projectile that needs to be launched is one centimeter smaller than the barrel, so that it will not rub against the magic array inside the barrel. As for the rate of fire ... the strength of this cannon is not that The rate of fire, so its rate of fire is actually not fast, at most it is only eight to ten rounds per minute. "
Although this speed is really slow compared to those machine guns with dozens of bullets a second, but Sufi's words are obviously too modest. You know that this thing is not a submachine gun. This is a naval gun. And it was the former gun. Does it take hundreds or thousands of rounds per minute? Moreover. Even with that rate of fire, how big is the ammunition depot for this cannon to keep up with its consumption? After all, the size of large-caliber shells is not small, and the shells fired by this gadget weigh several tons at one shot. Even Chris Dina is big. It ’s impossible to carry too many shells for the main gun?
Those children don't quite understand what an electromagnetic gun is. But still excitedly followed Sophie and asked for something else. One of the children probably knew what the electromagnetic gun was, so he seriously asked, "Sister, what is the range of this electromagnetic gun? I heard that the range of the electromagnetic gun is very long."
Sophie immediately heard the other's question and said, "If you do n’t specify a target, let me hit it casually. This cannon can fire cannonballs up to a thousand kilometers away, but unfortunately, the actual use distance of this thing is only two It's only 100 kilometers. "
"why?"
"Because the enemy is too far away, we can't see it!"
Sophie's answer is simple, but the children seem to understand, but I do understand. The electromagnetic gun's flying speed is fast, so the range will increase accordingly, but the problem is that there is no self-guided cannonball technology in the game, the guide arrow magic array also needs to be able to see the target in order to function, so even we can use a pilot ship In front of the investigation, there was no way to guide the shells to hit the target so far. In addition, there is another problem that affects the range of the electromagnetic gun, and that is its trajectory.
The velocity of the projectile of the electromagnetic gun is too high, so its trajectory is very straight. Although it is impossible for any solid ammunition to actually fly in a straight line on the earth, this line will be very close to a straight line. It's okay to say if the range is short, but the problem comes when the range is long. Because the earth is round, if the target distance is too far, it will be blocked by the raised sea level, and if the trajectory is curved, it can be ejected, but the problem is that the orbit of the electromagnetic gun is almost straight, so it cannot be carried out. Project. As a result, the target was blocked by the horizon, and the gun had no firing angle at all. Of course, although this relatively painful reason has limited the range of our artillery, it has to be said that this thing is still the farthest artillery currently known. After all, regardless of its trajectory, it can shoot a thousand kilometers. This range can only be described as heartbroken.
After explaining a few words, Sophie gradually lost her credibility, but here she is, so the captain Sophie directly gave the job of the narrator to several turret operators on the scene, and then she liberated herself. Come out.
As she ran out of breath, I asked, "Has this ship been tested?"
Sophie stood on the edge of the pedestal outside the turret, leaning against the safety rail, and said, "All the battleships of the leader class ... Oh, forgot to say. These battleships belong to the leader class, and the Kristina is just one of them. One. Our warships have basically not been tested. The technical Red Moon seems to have tested basic attributes such as short-range rapid acceleration. The Eagle battleship tested the floating system, but all the cannons of the warships were tested. Tested on the field, never tried with a battleship. "
"Aren't you testing?" Cristina asked.
"This time is the first voyage of Kris Dina, and it is also a test voyage. According to the original plan, we will deliberately find several islands at sea to test weapons power and range, and we will also test the power system during the voyage. . Later, after entering the sparse waters of the ship, it will be decided whether to test the floating system. "
"Still testing the floating system?" Cristina asked in surprise. "But there are outsiders on the battleship now!"
Before Sophie answered, I preemptively said, "This is not a problem, as long as the children are brought into the boat in the name of a visit. As long as the surface is not visible. Who knows whether the boat is sailing at sea or flying in the sky? what?"
"That's what I said." Chris Dina nodded. "Oh yes, I'm going to the bridge myself to pilot a warship of my own name. Is this all right?"
"Of course." Sophie said with a smile. "Anyway the sea is wide enough, you can't even rush to the shore even if you are stupid?"
"Are there still reefs?"
"Do you think I will let you sail in the waters with reefs?"
"That's true!"
As we were talking, we saw the turrets over there, and the children came out one after another. These children are now very excited, because they have just heard that they will test the artillery during the voyage, so they surrounded me as soon as they came out and asked if they could watch the test fire of the cannon.
Except for the flight system, other things of this warship are not considered confidential, so I did not refuse and just agreed. "Say good to you first. It's okay to watch. But you have to listen to the command and watch through the observation window inside the bridge."
"Why?" Asked the child, slightly disappointed.
"Because the instantaneous detonation of the cannon popping out of the chamber is enough to blow you all up," Kristina answered. Although this is an electromagnetic gun, there is no such thing as a muzzle flame, so it is not as shocking as the past gunpowder guns fired. But this thing is to radiate several tons of shells with several times the speed of sound. So the shock wave was still pretty scary. Although this shock wave will no longer hurt players like us. However, most of these children are not high-level, and their attributes are very bad. Most of their defenses can't stop these shock waves. Death does not happen. But being blown into the sea is also a hassle, isn't it?
Because I explained it reasonably, the children didn't have much noise, and then they gave up following us on my advice, and instead followed the ones that Sophie found and began to visit the battleship. This ship is nearly one thousand meters long, and it looks like a small city inside, enough for them to play in, so I can be considered to get rid of these energetic little guys temporarily.
After the surroundings were quiet, I went to the bridge with Sophie, at which point the warship had begun to slowly back up and leave the port. Half of the warships that had been parked side-by-side with Kristina before the Kristina were gone, and half of the warships immediately followed after we moved.
As the largest warship here, this Kristina is, of course, the flagship of this fleet. After leaving the port, Kristina turned to the south, while other warships quickly moved around the Kristina to form a cruise fleet, and then began to accompany the cruise.
"When are we going to test?" Now that I'm on board, I want to see the test results of this ship ~ EbookFREE.me ~ Although I may not have the opportunity to see the situation of several other leader-class battleships, but With the data of this Christina, I have a good idea. In the future, if there is anything that needs the support of the fleet, at least I can find a suitable target, right?
After hearing my question, Sophie didn't answer immediately, but looked at the chart first, and then said, "In about 20 minutes, we can reach an island group. There are uninhabited islands there, so I will find one. The hilltop can be tested. But before that we can test the navigation system first. "
"You mean the kind of test that accelerates extremely quickly?" Cristina asked a little worried.
Sophie looked at Kristina in surprise and asked, "What are you doing?"
Chris Dina said with a little embarrassment: "Actually I haven't said it, I'm slightly seasick."
"In the game?" Sophie and I were surprised this time.
Chris Dina shrugged. "I also know that this situation is very rare, but I'm just seasick, and I can't help it. If you're sailing normally, it's nothing, but if you are playing stunts at sea, I can't stand it." (To be continued ...)
