Great Country Academician

After the first round of conventional ammunition testing of the electromagnetic railgun, the open test site was already in a mess.

Taking advantage of the free time before preparing for the second round of shell testing prepared by the ‘active damage element technology’, a group of people came to the open test site.

After all, watching the experimental data and images sent back by various detectors and sensors in the observation room is far less profound than being there in person.

In the open test site, various targets used for experiments, concrete stone walls, and hard and thick steel plates have become a pile of rubbish under the bombardment of the Thor electromagnetic railgun.

Even the special steel used exclusively on the aircraft carrier is like the moon hit by a meteorite, with crater-shaped damaged holes all over the surface.

And those fragments and debris that were splashed due to the huge impact damage of the electromagnetic railgun can be said to be scattered all over the entire test site under the action of the shock wave.

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

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

"The 170mm composite special protective material was directly penetrated. Tsk tsk, the power of this electromagnetic railgun is even more powerful than I thought."

The fragments in his hand were torn 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 made 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, in other words, is actually a composite assembly of materials commonly used in military bulletproof vests.

Generally speaking, the cover of bulletproof vests is often made of chemical fiber fabrics.

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

This composite material can absorb the kinetic energy of bullets or shrapnel, has a significant protective effect on low-speed bullets or shrapnel, and can reduce the damage to the chest and abdomen of the human body under certain conditions of controlling the depression.

Compared with single steel or ceramic materials, this composite material has stronger protection against bullets, pure metal shells of electromagnetic railguns, and other 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 force 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, it is far superior to steel in terms of eliminating impact force and coping with pure kinetic energy weapons.

However, even with this composite material, which had a thickness of an astonishing 170mm, it still could not completely block the impact of the electromagnetic railgun and was torn into pieces.

This is enough to show how terrifying the lethality of the electromagnetic railgun at full firepower is.

Academician Wang Yong smiled and said, "The lethality of pure metal shells is still a little insufficient."

Looking at the messy test targets on the ground, Xu Chuan smacked his lips and couldn't help asking, "It's so powerful, is it still not enough?"

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

"This means that the current armor-piercing projectiles are difficult to cause secondary killing effects, and can only destroy enemy armor-type equipment by the jet generated when the core melts."

"So the current electromagnetic railgun technology still has a great improvement in lethality."

"Wait and see how the lethality of the shell material prepared by the 'active damage element technology' studied by Professor Wang Haifu is."

"In theory, it should be able to cause higher damage than pure metal shells, especially to units including armor protection."

Under the rapid cleaning of the staff, the messy test site soon returned to cleanliness.

The targets that had been blown up were cleared out by forklifts and shovels, and new target materials were transported in and fixed in the test site.

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

Compared with traditional pure metal shells and special alloy shells, the explosive materials made using this "active damage element technology" are mainly used to improve the core of armor-piercing shells.

The improved armor-piercing shells can theoretically detonate the core after penetrating the armor and achieve secondary killing within a closed range.

In other words, if it is used to prepare a type of shell such as shrapnel, it can not only achieve firepower 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 tests has been launched.

The first target to be destroyed 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 damaging 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 also Wang Yong and Wang Enge, including Ouyang Zhen, the head of the Navy Equipment Department, were looking forward to the second experiment.

How well this active damaging element technology, which once won the second prize of the National Technological Invention Award, matches the electromagnetic railgun depends on the next experiment.

After all, the "contradiction" between protection and penetration has always been a headache for weapon researchers.

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

As the first active damaging element shell was pushed into the gun case of the Thor electromagnetic railgun, the magnetic field indicator light at the tail of the narrow barrel jumped from light red to light green.

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

Accompanied by an intelligent reporting voice in the laboratory, the first active damaging 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 shells, the first thing that appeared in front of everyone was the impact damage caused by the massive kinetic energy carried by the shells hitting the stone wall.

Dust and gravel flew all around, and the stone wall that was as big as a hill was directly hollowed out into a huge pit.

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

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

The walls that were originally barely supported around were already partially unable to maintain balance after encountering the second wave of active damage explosions.

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

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

It can even be said that it is not even one percent of the damage of the first wave.

But its goal has been achieved.

If this shell hit a warship, then the personnel or equipment inside the warship would have suffered serious casualties or damage under the second wave of explosion.

Don't underestimate the small explosion power, that's just a comparison.

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

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

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

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

More importantly, the super-strong magnetic field attached to the electromagnetic railgun itself and the high-voltage current formed when it is fired did not cause irreversible damage to the active damage material inside the shell.

Regardless of its power, at least it successfully achieved secondary explosion damage that pure metal shells could not have caused.

This is a huge breakthrough for electromagnetic railgun technology!

In the observation room, Xu Chuan stared at the data and curves sent back by the detectors and sensors on the screen, and said after thinking for a while.

"4.2 megajoules."

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

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

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

Hearing this, Wang Yong was stunned again, looking at the messy and various detection and sensing data on the screen, and the whole person was a little confused.

After a long pause, he suddenly looked at Wang Enge who was standing on the other side and shouted, "Old Wang, did you tell him the performance of the active damage meta-cannon 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 a question on his face. It was obvious that he did not hear clearly what Academician Wang Yong said.

Academician Wang Yong took a deep breath and asked again, "I said, in the email you sent to Academician Xu before, did you also attach the performance data of the active damage meta-cannon shell?"

Wang Enge shook his head and said, "No, the active damage meta-cannon shell only arrived yesterday and has not been tested yet. Why would I send him the data of this thing?"

Hearing Wang Enge'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 in a puzzled tone: "How do you know that the energy generated 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 face.

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

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

When will their monitoring detection and sensors be able to accurately capture this kind of data?

He looked at the monitoring screen with some suspicion. When he tried to find specific data on it and found that he couldn't find it at all, he turned his eyes back to Xu Chuan and asked hesitantly.

"Isn't there this data on it?"

Xu Chuan smiled and said, "It's true that it doesn't appear on the surface, but it can be calculated with a simple calculation."

Hearing this, Academician Wang Yong's eyebrows twitched fiercely.

Nima?

What the hell? Can this thing be calculated from these monitoring data?

His eyes fell on the monitoring screen, looking at the monitoring data that was almost completely unrelated, and he began to doubt his life.

As an academician of the School of Engineering of the Naval University of Engineering, although he is not a scholar majoring in mathematics, he has been engaged in research on magnetic field physics and condensed matter materials for many years. He can't say that his mathematics is very good, but it is not bad.

After all, he can skillfully use mathematical tools to solve various problems encountered in these studies. The theoretical research that Xu Chuan sent over before, the theory about the analysis and calculation of three-dimensional elliptical electromagnetic fields and high-dimensional large-scale backscattering problems, is the mathematical model he led people to make.

This alone is enough to prove that his mathematical ability is not low.

But at this moment, looking at the messy real-time feedback data on the monitoring screen, he couldn't believe that someone could accurately calculate the energy of the secondary explosion of the active damage element material from it.

Looking at Wang Yong, who was suspicious and didn't believe him, Xu Chuan smiled and said, "Want to make a bet? After the test is over, it should be possible to systematically test the energy of the active damage element material explosion."

Hearing this, Academician Wang Yong came back to his senses, shook his head, and said, "There is no need to bet."

He didn't want to make such a losing bet.

In fact, the energy generated by the explosion of the active damage element material is indeed around 4.2 megajoules.

This data is actually the energy of the explosion of one kilogram of standard TNT explosives.

Professor Wang Haifu of Beijing University of Technology made the inner core according to this standard.

However, he just couldn't understand how there could be such a freak in this world who could calculate the energy generated by the secondary explosion of active damaged elemental materials based on such messy feedback data.

Is this really something a human can do?
