    "Start pressurizing the pressure chamber!" "Understood, pressurize the pressure chamber!" A technician repeated the order, looked up at the instrument panel, and pressed the pressure button.  The control room and laboratory have been soundproofed so that no one can hear the sound of the piston press working outside, and no changes can be seen through the thick bulletproof glass.  But from the console computer display, it can be clearly seen that the pressure in the pressure chamber is increasing.  There are two readings. One is the first-level pressure chamber. Due to the large space, the reading rises relatively slowly.  In the secondary pressurized chamber next to it, the readings were beating rapidly.  "The critical valve is approaching!" The technician looked at the screen intently and said calmly in a calm tone.  Everyone has increased their attention. Some people who can't squeeze to the console stand behind the bulletproof glass, staring at the front of the air cannon below without blinking.  "The pressure in the secondary pressure chamber has reached the critical valve, three, two, one!" As his last reading came out, the cube suddenly seemed to explode on the target at the front of the air cannon.  This speed is too fast. Since the target is firmly fixed on the steel frame and does not move, most people have no reaction. Occasionally, one or two people feel something strange, but they think it is because they are dazzled and still stare at the target closely.  , did not notice at all, the warhead had been fired just now and hit the armor plate.  Reflected on the computer screen, the pressure chamber readings are also dropping rapidly.  "What's wrong?" Many people were still unaware and asked in confusion when they saw the numbers jumping down on the screen.  "The air cannon has been fired, down below" "Ah? Already fired?" At this time, everyone suddenly realized that they hurriedly opened the door of the control room and rushed towards the air cannon room below.  Chief Engineer Zhu was very old, but he rushed to the front. It was difficult for others to compete with him, so they all got out of the way, allowing him to be the first to go down the stairs to the air cannon room and sprint to the target.  As the target of the experiment, it is a small one-foot-square composite armor plate. The left and right sides are firmly fixed on the base by clamps to withstand the impact and prevent it from tipping over.  The surface of the steel plate is sprayed with digital camouflage. Anyone who looks at it will know that it is an armor plate and will not regard it as an ordinary plate.  Chief Engineer Zhu was not in a hurry to observe the penetration results. Instead, he gently brushed his fingers over the edges of the polished armor plates and carefully observed the structure of the armor.  From the edge fault, it can be clearly seen that there are five layers of armor plates.  ?The outermost and innermost layers have the same bright silver metallic luster, which is naturally forged special alloy steel plates.  He measured it with a tape measure and found that each layer was seven centimeters thick.  The second and fourth layers are white. Chief Engineer Zhu, who knows the composite armor structure of the base, understands that these are compacted aramid fiberboards.  He also roughly measured it with a tape measure, and it was indeed the same as the target determined at the meeting, each layer was 1.5 centimeters thick.  It is sandwiched between two layers of alloy steel plates and aramid fiber boards at the core, showing a dark tone. This is a bulletproof ceramic plate with a thickness of three centimeters.  These five layers of materials represent five types of materials: hard and soft, and have different effects on the warhead. In this way, the penetration force is reduced layer by layer to achieve the protective effect of a single material armor.  When the warhead passes through the outer alloy steel plate, it will be blocked and dragged by the extremely tough aramid fiber plate in the inner layer to form a side force, forcing the warhead to roll, expanding the stress area and quickly reducing the penetration force.  When the warhead breaks through the aramid fiber layer and continues to advance, the extremely hard ceramic plate will become its next obstacle.  Since the warhead has been deformed in most cases at this time, it will become very difficult to penetrate the extremely hard ceramic plate.  And even if it breaks the ceramic plate, because when the ceramic is broken, it will spread to the surroundings in a network shape, so it will consume a lot of impact force. Even if it breaks through the blockage of the ceramic plate, it will be covered again by a layer of aramid fiber.  The net is used to block the warhead due to its fine mesh structure and strong toughness.  When the warhead can continue to advance, it will still face the interception of the last layer of alloy steel plates.  At this time, most of the kinetic energy has been consumed, and it will be much more difficult for the severely deformed warhead to penetrate the steel plate than it was when it penetrated the first layer of steel plate.  Composite armor is like this. Under the influence of different materials and different physical properties, it tries its best to deform the incoming warhead, change the impact direction, consume kinetic energy, and ultimately achieve the purpose of protecting the members behind the armor.  It is precisely because of these unique combination designs that the armor plate, which is only 20 centimeters thick, can exert more than double the protective power.  I wish the Chief Engineer confirmed that the armor plate was indeed made according to the specifications determined at the original meeting, and even scratched off the edge.?Powder, carefully wrap it on white paper and prepare it as a sample for testing.  After that, he looked towards the site where the bullet hit.  The hit part of the armor is located in the center, opening a small hole in the digital camouflage.  The hole is not big, no bigger than your little finger, but judging from the inner diameter of the hole, it is very smooth.  ¡°Obviously, the penetrating power of the warhead is extremely high. The alloy steel plate with a thickness of seven centimeters is penetrated easily like a scalper in front of it. It has no blocking effect at all, which is why such a smooth and round hole is formed.  He took out a bamboo chopstick from his pocket and pushed it in along the small hole until it was blocked and could not go deeper.  Hiss!  The surrounding people held their breath, and the experts onlookers all gasped in unison, as if they had toothache.  The chopsticks only go in a small amount.  By visual inspection, it¡¯s less than eight centimeters!  I actually measured it with a tape measure and it was indeed only 7.3 centimeters.  In other words, the warhead has not even penetrated the aramid fiber layer. To put it more broadly, the warhead is stuck inside. Considering the size of the warhead, it has only just penetrated the aramid fiber layer, but the kinetic energy has been exhausted.  , was blocked out by the ceramic layer, and not a single bit penetrated.  "How much is the blocking diaphragm that was placed just now?" He asked without raising his head, still observing the small hole intently.  He actually remembered the specific value very clearly, but he still asked.  "It seems to be three hundred penetration." "That's the number." "It's amazing. A warhead with three hundred penetration didn't even break through the ceramic plate! According to this calculation, the protective power of this armor is not four hundred. I think  Maybe it can reach five hundred!" "What is the theoretical value we calculated?" "Five hundred and thirteen, it is basically the theoretical maximum value!" The experts woke up from the shock and started talking excitedly.  Some of them didn't quite know what it meant and were simply elated, but for Chief Engineer Zhu and the armor experts, this was an incredible and major achievement.  The kinetic energy of the warhead does not decrease proportionally, but decays rapidly in a curve.  Therefore, if the protection power is only 400, then the warhead will at least penetrate the ceramic plate in the early stage, and then stop moving in the second layer of aramid fiber.  But the most optimistic estimate now is that it has just stopped in front of the ceramic plate. Maybe it is still stuck in the aramid fiber layer. That would be terrible!  Four hundred?  Five hundred is possible!  It may not even reach the maximum value in theoretical design!  Theory usually only represents the upper limit, and it is basically impossible to achieve it in practical applications. Being able to get a little closer to the theoretical value is a very remarkable performance, which shows that the designer has extremely profound skills to design the theory.  for reality.  Judging from their early contacts, although Guan Fei knew a lot and was proficient in electronics, mechanics, and chemistry, that was all general knowledge about civilian products, and he was not deeply involved in weapon design.  In the previous meeting, he also asked them, experts from China, about many relevant requirements, design principles, and key elements, which showed that he really did not understand them very well.  ¡°However, the design plan that he guided and finalized was actually able to achieve an actual effect close to the theoretical maximum, which was completely beyond the expectations of Chief Engineer Zhu and the others.  This is still the best angle of incidence of ninety degrees. If welded according to the tilt angle of the turret design, it is not difficult to achieve a protective power of 600 or 700! ???????? Is this a blind cat who bumped into a dead mouse by mistake, or did he actually hide it deeply and calculated it through careful design?  They stood around the armor without saying a word, testing it silently and recording the test data in notebooks.  "Actually, there's no need to bother. We have flaw detectors here, including digital acoustic flaw detectors and eddy current flaw detectors. I think it's better to put the number on this board, put it down, replace it with a new one, and continue testing until it finally breaks down, and then  It would be better to go to the laboratory for unified testing." Guan Fei coughed and reminded tactfully.  "There is no need to replace it with a new one, it's such a waste!" Chief Engineer Zhu shook his head repeatedly. Every time they do an experiment, they have to write tens of thousands of words in the calculation draft. After repeated demonstrations and confirmation that it is feasible, they will report to their superiors to apply for funds.  Each approval is only a few hundred or thousands of dollars.  A penetration test like this requires the use of special alloy steel, aramid fiberboard, and bulletproof ceramics. It must be coordinated with other research departments. Only when a certain amount is accumulated can one be willing to smelt it, and then distribute it to several or dozens of people.  Used by projects.  It is also very economical to use after that. A plate will always be riddled with holes and will be abandoned when it can no longer be used. That's it, the scrapped steel plate has to be returned to the steel factory.??New furnace.  This board was left unused after just one hole was pierced. Replace it with a new board. This is simply a shame. Oh, by the way, this field was originally made by him. Mr. Zhu sighed deeply and advised.  : "Comrade Guan Fei, this piece of armor can still be used. I think it will be replaced with a new one after a few more tests." Other experts also echoed.  Guan Fei smiled bitterly and said: "I'm not lavish. It's just that if you do too many tests on the same board, it will be difficult to tell which of the scattered warhead fragments were left behind, which can easily lead to detection errors. I think so  Well, this board is big enough. Since there is a hole in the center, the spread range is limited to this small area. Then we will use the four corners and do another experiment respectively, so as to maximize the use of this area.  Armor saves costs and can get more accurate test results. What do you think? ""Actually, the four sides and the area near the center are okay," one expert said with some reluctance.  Guan Fei looked at them, and for some reason, his mood suddenly became very complicated.  They belong to different eras. In Guan Fei's era, technology was extremely advanced and materials were extremely abundant. He never had the idea of ??being too frugal.  However, these experts are used to living a hard life of cutting down on clothing and dieting. They save on the equipment they can save, use domestically produced instruments instead of importing them, plan experiments half a year in advance, and use homespun methods to save money as much as possible.  If you have a penny, it's hard to break it in half and spend it.  And these people, with Guan Fei's seemingly stingy frugality, have become the mainstay of the military industry. They have developed a variety of weapons and equipment that are not inferior to those of other countries. They can use national power and investment far lower than that of the United States and the Soviet Union.  Support the national defense of a big country.  It¡¯s not like they don¡¯t know that the base area doesn¡¯t care about this experimental loss.  This is purely reluctance!  For the latest book update address, please click Yunlai.ge to get the latest chapters of this book.
