The first round of conventional ammunition test experiments for the electromagnetic railgun ended, and the open test site was already in a mess.

Taking advantage of the free time before preparing for the second round of testing of artillery shells prepared by the 'Active Destruction Element Technology', a group of people came to the open test site.

After all, looking at the experimental data and images transmitted by various detectors and sensors in the observation room is far less profound than being there.

In the open test site, various targets used for experiments, concrete stone walls, hard and thick steel plates... had been turned into a pile of junk under the bombardment of the Thor electromagnetic railgun.

Even the special steel used on the aircraft carrier is like the moon being hit by meteorites, with crater-shaped damage holes all over the surface.

As for the fragments and debris that were scattered due to the huge impact damage of the electromagnetic railgun, it can be said that they were almost scattered throughout the entire test site under the action of the shock wave.

Standing next to Xu Chuan, Academician Wang Yong smiled and said, "How do you feel?"

In the open test site, Xu Chuan bent down and picked up a broken piece of armor from the ground, the size of an adult man's palm, and said:

"The 170mm composite special protective material was directly penetrated... Tsk tsk... The power of this electromagnetic rail gun is more powerful than I imagined."

The fragments in his hands were torn pieces from the huge composite special protective material used for testing in front of him.

From the completely distorted cross-section, it can be clearly seen that this protective material is constructed of several layers of different materials.

There are nylon materials, Kevlar boron carbide ceramic plates, and ultra-high molecular weight polyethylene fibers...

In fact, this so-called composite special protective material, to put it another way, is actually a composite assembly of materials commonly used in military body armor.

Generally speaking, body armor covers are often made of chemical fiber fabrics.

The bulletproof layer is made of metal, or ceramic sheets, fiberglass, nylon, Kevlar, ultra-high molecular weight polyethylene fiber, liquid protective materials, polyimide fiber and other materials.

This composite material can absorb the kinetic energy of warheads or shrapnel, has obvious protective effects on low-speed warheads or shrapnel, and can reduce damage to the human chest and abdomen while controlling a certain depression.

Compared with single materials such as steel or ceramics, this composite material has stronger protective capabilities against bullets, pure metal shells of electromagnetic railguns, weapons that rely on pure kinetic energy to cause damage.

Because its internal buffer layer is used to dissipate impact kinetic energy and reduce non-penetrating damage.

Generally speaking, a composite protective material of about six to nine centimeters is enough to stop ordinary rifle bullets and buffer the impact to the point where it will not cause any harm to the human body.

Although it cannot be compared with special steel in terms of hardness, its performance in eliminating impact force and dealing with pure kinetic energy weapons is far superior to steel.

However, even this composite material, with an astonishing thickness of 170mm, was still not able to completely block the impact of the electromagnetic railgun, and was torn into broken pieces.

It is enough to show how terrifying the lethality of the electromagnetic rail gun with full firepower is.

Academician Wang Yong smiled and said: "The lethality of pure metal shells is still somewhat insufficient."

Looking at the messy test targets on the ground, Xu Chuan clicked his tongue and couldn't help but ask: "You are so powerful, is this not enough?"

Wang Yong nodded with a smile and explained: "From the perspective of lethality, whether it is a special alloy armor-piercing projectile or an armor-piercing projectile made of depleted uranium materials, it cannot change the fact that the core of the sabot-stabilized armor-piercing projectile can only penetrate but not explode."

."

"This means that it is difficult for current armor-piercing bullets to cause a secondary killing effect. They can only rely on the jet generated when the bullet core melts to destroy enemy armored equipment."

"So the current electromagnetic railgun technology has greatly improved in terms of lethality."

"Let's wait and see how the lethality of the artillery material prepared by the 'active damage element technology' studied by Professor Wang Haifu is."

"Theoretically, it should be able to cause higher damage than pure metal shells, especially to units protected by armor."

.......

With the quick cleaning by the staff, the messy test site was quickly restored to clean and tidy.

The damaged targets were cleared away using forklifts and forklifts, and new target materials were transported in again and fixed in the test site.

The second round of experimental tests used artillery shells made from explosive materials that Professor Wang Haifu and his team had improvised through active damage element technology.

Compared with traditional pure metal artillery shells and special alloy artillery shells, the explosive materials prepared by this "active damage element technology" are mainly used to improve the cores of armor-piercing projectiles.

The improved armor-piercing projectile can theoretically detonate the core after penetrating the armor, achieving secondary damage within a sealed range.

In other words, if it is used to prepare bullets such as shrapnel, it can not only achieve fire coverage with fragments and projectiles, but also detonate fragments and projectiles to further expand the killing range.

In the observation laboratory, the second round of testing has already begun.

The first target of destruction was also a stone wall made of stone mixed with a small amount of soil.

This is actually an imitation of an ordinary mountain structure.

When the first active damage element shell was pushed into the gun case of the Thor electromagnetic railgun, in the observation room, not only Xu Chuan was looking forward to it, but Wang Yong and Wang Enge, including Ouyang Zhen, the chief of the Naval Equipment Department, were all looking forward to the first

Second experiment.

How well this active damage element technology, which has won the second prize of the National Technology Invention Award, matches the electromagnetic railgun will depend on the next experiment.

After all, the "contradictions" of protection and penetration have always been a headache for weapons researchers.

Due to the development of material technology, armor-piercing materials and protective materials have shown a trend of increasing in number. No one knows which technology will be more advanced tomorrow.

...

As the first active damage element shell was pushed onto the gun box of the Thor electromagnetic railgun, the magnetic field indicator light at the end of the narrow barrel jumped from light red to light green.

"Charging is complete, the current Thor's magnetic field strength is stable, and the second round of testing is about to begin."

As an intelligent report sounded in the laboratory, the first active damage element shell hit the stone wall hundreds of meters away at a speed that could not be captured by the naked eye.

Just like the first round of pure metal cannonballs, the first thing that appeared before everyone's eyes was the impact damage caused by the massive kinetic energy carried by the cannonball itself hitting the stone wall.

Dust and gravel flew all over the sky, and a huge pit was hollowed out of the hill-like stone wall.

As the first round of explosions sounded, under the gaze of everyone, the second round of explosions came from inside the stone wall used for testing.

In the crater caused by the first round of shell impact, the violent blast was like a time bomb installed inside, directly blasting and collapsing the originally intact stone wall.

The surrounding walls that were originally supportive were partially unable to maintain balance after encountering the second wave of active damage blasts.

Like a landslide, a small part of the stone wall collapsed again.

Although judging from the power of the explosion, the damage caused by the material of the second active damage unit is far from comparable to the first wave of impact.

It can even be said that there is not even 1% of the first wave of damage.

But its goal has been achieved.

If this shell hit a warship, then the second wave of explosions would have caused serious casualties or damage to the personnel or equipment inside the warship.

Even though the explosion power is small, it is just for comparison.

After the first round of impact damage caused by the warhead hitting the target at a high altitude, a second explosion is generated and the secondary strike has penetrated the protective layer, and the internal blow will be fatal.

...

In the observation room, experimental data item by item is transmitted back through the sensors or detectors arranged in the test site.

Looking at the pictures on the monitoring screen and related experimental data, Academician Wang Yong waved his hands excitedly, clenched his fists and said excitedly: "Beautiful!"

Although only the first active-destruction element artillery shell has been tested so far, the damage and explosion in the front and rear rounds have confirmed that the artillery shell made of this new material does have a two-round killing method!

More importantly, the ultra-strong magnetic field attached to the electromagnetic railgun itself and the high-voltage current generated when it is discharged from the barrel did not cause irreversible damage to the active damage materials inside the projectile.

Regardless of its power, at least it successfully achieved secondary blast damage that is impossible with pure metal shells.

This is a huge breakthrough for electromagnetic railgun technology!

In the observation room, Xu Chuan stared at the data and curves transmitted by the detectors and sensors on the screen, thought for a while and then spoke.

"4.2 megajoules."

In the room, Academician Wang Yong was stunned for a moment after hearing this number, and was a little unresponsive.

He glanced at Xu Chuan with some surprise and curiosity, and asked: "What?"

Xu Chuan said calmly: "The secondary explosion, that is, the energy formed by the explosion of the active damage material in the shell, should be about 4.2 megajoules."

Hearing this, Wang Yong was stunned again. Looking at the messy detection and sensing data on the screen, he felt a little confused.

After being stunned for a while, he suddenly looked at Brother Wang Eng who was standing on the other side and shouted: "Old Wang, have you told him the performance of the active damage element shell?"

"What?"

In front of the monitoring screen, Academician Wang Enge, who was staring at the monitoring screen, turned his head and looked over with doubt on his face. Apparently he did not hear clearly what Academician Wang Yong said.

Academician Wang Yong took a deep breath and asked again: "Let me tell you, in the email you sent to Academician Xu before, did you also include the performance data of the active damage element shell?"

Brother Wang Eng shook his head and said: "No, the active damage yuan cannonball just arrived yesterday and has not been tested yet. Why should I send him the data of this thing?"

After hearing Brother Wang Eng's answer, Academician Wang Yong showed a suspicious look on his face.

After staring at his old friend, he shifted his gaze to Xu Chuan and asked with a puzzled tone: "How do you know that the energy formed by the explosion of active damage materials is about 4.2 megajoules?"

Xu Chuan smiled faintly, pointed to the experimental data transmitted back in real time on the monitoring screen, and said, "Isn't it there?"

Hearing this, Wang Yong looked at the monitoring screen with a blank expression.

Looking at the messy monitoring and sensing data transmitted back in real time, everyone was a little confused.

Where is the energy data generated by the explosion of active damage materials?

When will their surveillance probes and sensors accurately capture this kind of data?

He glanced at the surveillance screen with some suspicion. After trying to find specific data on it, he found that he couldn't find it at all. Then he turned his gaze back to Xu Chuan and asked hesitantly.

"There's no such data... right?"
