Great Country Academician

The first electromagnetic sniper rifle! (asking for monthly votes)

The test of shells prepared for active damage element materials is still ongoing.

Whether it is the size of the shells, the magnetic field energy level strength of the electromagnetic railgun, or the target material for targeted testing, the strength is steadily and orderly increasing.

Fortunately, the test site is large enough to complete all the experiments.

As time passed, the second round of tests ended in an orderly manner.

Different data were reported by various sensors or manually, and presented to everyone in the control room.

These are all raw data, and they will be processed by the supercomputing center later.

In particular, the first round of impact damage damage intensity and the second round of explosion damage intensity formed by active damage element shells and conventional metal shells are very critical indicator data.

You must know that the amount of active damage element materials in active damage element shells is different.

Different types of shells have different weights of active damage cores, and the secondary damage caused is also different.

Including the degree of damage to different target materials, etc., these experimental data need to be recorded one by one for further analysis.

While waiting for the supercomputing center to analyze and process the experimental data, the group came to the test site again.

The test site bombed by the active damage element shells looked more messy than the first round of pure metal shells.

Especially in the place close to the target, affected by the secondary explosion of the active damage element core, the target material was torn into more fragments.

Looking at the target stone wall in front of him, through the hole pierced by the electromagnetic railgun, Xu Chuan leaned over to look inside, and reached out to grab a piece of silver-white material from the wall.

"Is this the kind of active damage element material?"

Holding the fragment in his hand, Xu Chuan looked at it curiously. The silver-white material looked like metal, but he could clearly tell that it was probably not a metal material, but more like a ceramic material or a high polymer material.

Standing next to him, Academician Wang Enge nodded and said, "Well, a part of it, the component of the inner core."

Hearing this, Xu Chuan asked with interest, "Speaking of which, what exactly is this active damage element material?"

Although he knows a little about materials science, he doesn't know everything.

For example, he doesn't know what this active damage element material that can cause secondary damage through electromagnetic railguns is.

After all, before this, he had never been exposed to this type of technology and related theories.

After taking the silver-white fragment from Xu Chuan, Academician Wang Enge looked at it and said, "I have read Professor Wang Haifu's paper."

"This active material damage element is a composite material that combines an energetic warhead with mechanical strength similar to that of metals, chemical energy equivalent to that of high-energy explosives, and safety similar to that of inert materials. It will only explode after hitting the target at high speed."

"Its manufacturing process should be to fill energetic powders such as metals, alloy metal compounds, etc. in high molecular polymers, and then prepare them through special processes, so they can be directly machined."

"So the overall Good mechanical strength, this piece of material should be the polymer composite metal material in the inner material of the active material damage element. "

"After it hits the target at high speed, it will explode from the inside out like a fragmentation grenade, forming various fragments with high kinetic energy. "

"These fragments can have a huge lethality to personnel and electronic equipment inside the armor. "

"Previous inert metal damage elements can only damage targets through pure kinetic energy, while this new type of material damage element has the dual destructive capabilities of kinetic energy armor penetration and explosion, and the power will be multiplied. "

"However, compared with traditional high-performance explosives, this active fragmentation will eventually There are two conditions for the power to be exerted. "

Xu Chuan looked over curiously and asked, "Which two conditions?"

Academician Wang Enge smiled and said, "The first is that it needs to have enough kinetic energy or speed to effectively penetrate the target shell or skin."

"The second is that it can reliably detonate after penetrating the target shell."

"So its adaptability is not very high on traditional missiles or weapons."

Hearing this, Xu Chuan's eyes lit up and he quickly added, "But the electromagnetic railgun can perfectly make up for these two conditions!"

Academician Wang Enge smiled and nodded, "Yes."

"The electromagnetic railgun can first bring extremely high speed and kinetic energy, armor-piercing bullets can also effectively penetrate the protective target shell. "

"And the active damage element material inside it can also be effectively detonated under high-speed impact, further causing greater damage. "

"So it is simply a material born for electromagnetic railguns. "

"It's just that we have not been able to solve the problems of orbital ablation and magnetic field control of electromagnetic railguns before, so this technology has been buried in the past. "

After checking the degree of damage of various target materials in the test site, I returned to the laboratory with some data recorded in person, and the supercomputing center also came out with some processing data of the experimental data.

The data transmitted through the intranet was distributed to several people. Looking at the analysis data on the tablet, Academician Wang Yong's pupils shrank sharply.

4.18MJ, 6.25MJ, 8.35MJ

Several key figures caught his eye. These data were exactly the energy after the secondary explosion of the active damage element cores inside different active damage element shells.

The number was not surprising, and he had even known for a long time that the energy intensity of the secondary explosion of these shells was almost this number.

What shocked him was that there were actually people in this world who were able to accurately calculate these values ​​with just a little bit of raw observation data.

This simply refreshed his understanding.

Is there a quantum computer in this person's brain?

After reviewing the experimental analysis data in his hand, Academician Wang Yong suddenly remembered something, put down the tablet in his hand, looked at Xu Chuan, and said with a smile.

"Academician Xu, the experimental analysis data of the electromagnetic rail gun will probably have to wait for a while, but we have some other research on the electromagnetic rail gun technology. Do you want to take a look?"

With such a top leader in academia here, there is no need to use it in vain.

Xu Chuan didn't care about this. He glanced at Academician Wang with some curiosity and surprise, and asked in surprise: "Besides the Thor, are there other products?"

He thought that the Thor electromagnetic railgun was the research result of the National Key Laboratory of Electromagnetic Energy Technology during this period, but he did not expect that it still existed.

Academician Wang Yong said with a smile: "There is indeed another one, but it is not mature enough and has a lot of problems. Come over and have a look together? Can you guide our research?"

Xu Chuan didn't think much, nodded and said, "What new things have you researched?"

"Let's go, you'll know when we get there."

Academician Wang Yong said with a smile and took the lead to walk outside the laboratory.

Passing through the corridor, the group entered another laboratory.

In this large laboratory, Xu Chuan saw another product related to electromagnetic railgun technology.

It was a long and narrow product placed on a white ceramic experimental table. The overall length reached nearly two meters. The black shell and smooth curves made it look very sci-fi.

"Electromagnetic rifle?"

Seeing the products on the white ceramic experimental table, Xu Chuan glanced at Academician Wang Yong in surprise: "Have you made this thing?"

Academician Wang Yong smiled, nodded, and said, "This is another product I'm talking about, a miniaturized electromagnetic rail gun."

"Of course, you can call it an electromagnetic rifle. But really speaking, given the length of this thing, it might be more appropriate to call it an electromagnetic sniper rifle."

Since they can solve the problems of orbital ablation and magnetic field control of the electromagnetic railgun, after developing the Thor electromagnetic railgun, they have no reason not to try to miniaturize it and reduce it to a size that can adapt to The size of a single soldier.

After all, the entire length of the Thor electromagnetic railgun reaches an astonishing 15.55 meters.

Perhaps many people may not have an idea of ​​this number, but in fact, when it is erected, it is as high as five floors of residential buildings.

With such a huge size, not to mention individual combat, even equipment such as tanks and aircraft cannot be installed.

The only platform that can carry it is probably a large warship at present.

For electromagnetic railguns, the larger the size, the larger the power supply required.

Even if room-temperature superconducting materials are now available, the amount of electrical energy required to convert them into a critical magnetic field that is enough to support the high-speed launch of cannonballs is not a small amount.

After all, energy is always conserved. How high a speed you can accelerate a cannonball to and how much damage it causes requires at least the same amount of energy.

Miniaturization is the next research direction of electromagnetic railguns.

In particular, electromagnetic rifles or electromagnetic sniper rifles that are small enough to be used by individual soldiers are a key research direction.

The miniaturized electromagnetic railgun, or electromagnetic sniper rifle, with a length of 2.5 meters, is the product they created on this basis.

The same room-temperature superconducting material is used, and the 2.5-meter length contains two 2.25-meter-long room-temperature superconducting acceleration tracks.

The remaining parts are the power supply system, ammunition system, control system, aiming system, firearm structure, safety mechanism and other structures.

In the laboratory, Academician Wang Yong introduced: "This electromagnetic sniper rifle is 2.5 meters long and equipped with a microprocessor or microchip, which can be used to control the launch of ammunition and perform safety locking to prevent inadvertent triggering or ensure Firearms are in safe condition while being maintained.”

"As for the supporting power system, it is currently using a large-capacity lithium-sulfur battery with a trigger mechanism, including a 'charging area' and a 'firing area', allowing the user to have certain control when deciding whether to launch."

Listening to Academician Wang Yong's introduction, Xu Chuan's eyes fell on the electromagnetic sniper rifle on the white ceramic experimental table and asked with interest.

"Is this electromagnetic sniper rifle completed?"

"I mean, is it available now?"

Hearing this question, Academician Wang Yong smiled and nodded, saying: "Of course."

"In terms of use, it is ready for use now. I have tried shooting before."

After a slight pause, his eyes fell on the electromagnetic sniper rifle on the experimental table, and he said with a sigh:

"However, if we want to actually equip it with military soldiers, there are still many problems that need to be solved compared to the electromagnetic rail gun."

"Especially in terms of energy density and release density, there are still some big problems."

In fact, in principle, the electromagnetic sniper rifle in front of them and the Thor electromagnetic railgun they just tested are the same thing.

Both are weapons that convert external energy (electricity) into magnetic drive to make solid projectiles fly at high speed.

The principle of electromagnetic kinetic energy weapons is not complicated, it is a basic application of Lorentz force. The basic principle is the conversion of electrical energy into kinetic energy.

This basic principle was learned in the physics course in middle school.

Using electro-magnetic conversion, objects can be driven to accelerate flight.

Although the principle is not complicated, the weaponization process is still very troublesome. The main bottleneck is energy density and release speed.

Electromagnetic kinetic energy weapons are essentially electrical energy consumption, and one of the troublesome things about electrical energy is storage density.

That is, the energy that can be stored per unit weight.

Even the current electromagnetic technology has been updated several times in the hands of the person in front of him.

Lithium-sulfur batteries with energy density as high as 2000Wh/Kg have been developed, but for electromagnetic sniper rifles, this energy level is still a bit insufficient.

However, compared with another problem, the energy release density, energy density is only a small problem.

Chemical energy can be released very quickly, and a large amount of energy can be released in milliseconds. Even general propellants have to consider reducing this release speed to have so-called slow-burning propellants.

The release of electrical energy is a bit troublesome. The release per unit time is the so-called power limit, which is far lower than chemical energy. Otherwise, various incidental problems such as high pressure and high heat risks are all problems.

Why is the huge Thor electromagnetic railgun easier to implement?

Here is the reason.

The huge Thor electromagnetic railgun can be equipped with more other power devices and slow-release devices to increase power and reduce various risks.

The electromagnetic sniper rifle obviously does not have the ability to be equipped with these slow-release devices.

After all, it is for soldiers to use in single combat.

At present, the length of 2.5 meters and the weight of more than 60 kilograms are far beyond the bearing capacity of single combat.

If various power devices and slow-release devices are added to it, according to his estimate, the weight may exceed 100 kilograms.

For a soldier, this is an extremely exaggerated number.

I'm afraid that even the best soldier in the army cannot fight while carrying an electromagnetic sniper rifle weighing more than 50 kilograms. This is far beyond the limits of the human body.
