"Power meets standard!"

Looking at the Chinese characters displayed on the holographic image, both Lü Yongchang and Professor Yevgeny beside him showed gratified smiles.

The biggest hurdle for the electromagnetic railgun has been overcome!

"Professor, I have bad news."

Just as the two were overjoyed, Zero's voice rang out, throwing a bucket of cold water on them.

“…You go ahead.” The smile on Lü Yongchang’s face vanished instantly.

The holographic image was instantly magnified.

Then, a spectacular scene appeared before the two of them.

On the ground outside Mars City, a huge electromagnetic railgun sits quietly.

The key component of the electromagnetic railgun, the barrel, is over fifty meters long.

Inside the cannon barrel are two parallel, gleaming tracks.

That's the most important part of the electromagnetic railgun: the acceleration rail.

Inside the acceleration track, there are countless superconducting coils.

At the rear of the gun barrel is a massive base.

Inside the base are the most important superconducting magnetic energy storage device and the rest of the equipment.

"Professor, this is a simulation of the electromagnetic railgun designed by Professor Yevgeny," Zero's voice rang out.

Lu Yongchang nodded slightly, a hint of confusion in his eyes: "Is there a problem?"

In his view, this electromagnetic railgun is perfect in both its appearance and the structural design of each part.

“The problem is serious.” To draw Lü Yongchang’s attention, Zero deliberately adopted a somber tone. “Next, I will conduct a real-time simulation of the launch footage.”

As soon as he finished speaking, a projectile fell into the launch port.

“Professor, the projectile material is tungsten alloy according to the design plan.” Zero returned to his calm tone. “Now, I will simulate the launch scene.”

In the simulated image, the superconducting magnetic energy storage device at the bottom of the electromagnetic railgun begins to charge.

In less than a second, the superconducting magnetic energy storage device was filled with enough electrical energy for one launch!

Subsequently, the superconducting magnetic energy storage device poured all its energy into the electromagnetic railgun in just a few milliseconds!

An unexpected incident has occurred!

In the next instant, the middle section of the cannon barrel exploded with a deafening roar!

Molten metal slowly flowed out from the broken cannon barrel.

The simulated visuals were very realistic, and combined with the holographic display, even without sound, the two people felt as if they were actually there.

The moment the cannon barrel exploded, Lü Yongchang's breath caught in his throat, and he instinctively held it.

"This..." Yevgeny's voice, still shaken, came from the side, "What's going on?!"

Before Ling could speak, Lü Yongchang had already figured out the reason.

He said in a deep voice, "Yevgeny, there's a problem with the bullet."

"A projectile?" Yevgeny was still reeling from the sight of the gun barrel exploding, his eyes filled with panic. "How could a projectile..."

Halfway through his sentence, Yevgeny realized the problem.

He swallowed hard and said, word by word, in broken Mandarin, "You mean... this bullet melted under the powerful electric current?"

Lü Yongchang nodded with a wry smile.

Even he subconsciously overlooked one problem.

The initial simulations were all based on ideal conditions.

"Although the coils and various components all use superconducting materials, we overlooked one point."

"The projectile of the electromagnetic railgun, as the connection point between the two rails, has resistance." At this point, Lü Yongchang shook his head helplessly, "Zero, re-simulate the scene that failed just now."

In the holographic image, it was as if time had reversed, and the scene returned to the second before the launch.

"Zero, let's change the perspective and show the bullet's status in real time."

The images in the holographic projection change instantly.

A projectile with a silvery-white metallic sheen lay quietly between two acceleration tracks, connecting the two independent tracks to form a complete closed loop.

"Zero, slow down the entire launch process."

"Received, Professor."

The scene changes again.

To visually demonstrate the entire launch process, Zero specifically marked the direction of the current flow.

The current flows through the acceleration rail on the left, through the metal projectile, and into the other acceleration rail.

The entire silver-white bullet turned red at a speed visible to the naked eye.

Subsequently, under the influence of the electromagnetic field, the energized projectile, under the action of the Ampere force, rushed forward along the guide rail!

During this process, the surface of the projectile becomes increasingly red until it turns into a mass of molten metal!

Immediately afterwards, the sight of the cannon barrel exploding appeared before their eyes once more.

"..."

Silence.

Lü Yongchang and Yevgeny stared silently at the broken cannon barrel in front of them.

...

"Professor, we have failed..."

More than ten minutes later, Yevgeny sat in his laboratory seat, looking dejected, and said, "It's not just the projectiles; our guide rails also face extremely serious ablation problems under high-speed launch."

Lu Yongchang didn't speak, but stared solemnly at the holographic image in front of him.

good.

Even if the projectile can withstand the extremely powerful current, at a speed of 5,000 km/s, the rails of the electromagnetic railgun will suffer extremely severe ablation!

According to Zero's simulation, even if the projectiles do not malfunction, the acceleration rails of the electromagnetic railgun will be on the verge of becoming unusable after firing ten times.

This was clearly unacceptable to Lü Yongchang.

We can't just call a pause to change cannon barrels at the very beginning of an interstellar war, can we?

Wouldn't the Proxima Centauri laugh them to death?

"Let's change the plan."

After a moment of silence, Lü Yongchang sighed softly and said, "It seems that electromagnetic railguns are not feasible."

"We need to change direction."

"Let's try out the electromagnetic coilgun."

Compared to electromagnetic railguns, electromagnetic coilguns have a more complex operating principle.

Unlike railguns, electromagnetic coil guns are devices that accelerate magnetic materials to extremely high speeds using a projection accelerator composed of countless coils.

Although both are electromagnetic guns, electromagnetic coil guns contain a higher level of technology.

"coilgun?"

Yevgeny frowned, stood up, and began to think.

Indeed, coilguns can avoid a series of accidents that occur with railguns.

The projectiles of an electromagnetic coil gun are made of magnetic material and do not come into contact with the gun barrel.

To be precise, the projectiles of an electromagnetic coil gun are suspended in the barrel under the constraint of the magnetic field.

This directly solved the problem of barrel erosion.

No current flows through the inside of the projectile, so it does not generate any heat.

This fundamentally solved the problem of barrel explosion in railguns.

However... every advantage has its disadvantages.

Compared to electromagnetic railguns, electromagnetic coilguns inevitably have their disadvantages.

Due to structural complexity and issues such as coil synchronization, the stability of projectile launch is not very good.

This is also why humans chose to study electromagnetic railguns in the past.
