It's reasonable for me to have a two-way foil for a second-level civilization, right?

Listening to the string of quick tongue-tapping sounds, Lu Yongchang laughed and walked out of the office.

Only Yevgeny was left standing at the door of the room blankly, staring blankly at Lu Yongchang's gradually receding back.

"Why are you standing there?" Lu Yongchang's voice came from the front, "Follow me to the testing ground."

The confusion in Yevgeny's eyes dissipated instantly, and after a reply, he chased after Lu Yongchang.

……

"Professor, is this a superconducting magnetic energy storage device?"

Seeing a huge device made of coils on the test field, Yevgeny's eyes showed a bit of astonishment, and he asked in a low voice.

"That's right." Lu Yongchang patiently explained the reason for choosing this device.

"……I see!"

Yevgeny suddenly said: "According to this, with room temperature superconducting technology, this thing is indeed a perfect energy storage device for electromagnetic guns."

Lu Yongchang nodded lightly, did not say any more nonsense, and said directly: "Zero, has the electromagnetic gun simulation calculation been completed?"

"The calculation is complete!"

Zero's voice sounded in the speaker, and then the hologram listed the calculation results in front of the two of them.

Looking at the demand for energy and energy storage equipment above, Yevgeny smacked his lips lightly.

This exaggerated statistic... In the past, he didn't even dare to think about it!

but now……

Yevgeny looked at the device in the distance, with a look of anticipation in his eyes.

Maybe, he can see the giant ship and cannon scene in his dream!

"Zero, start the first charge and discharge test!"

Lu Yongchang, who saw the data, slightly raised his eyebrows, and said directly.

The next moment, the lights in the venue dimmed for a moment.

Not only the lights of the proving ground, but also the lights of the entire Martian city dimmed a bit at that moment!

That is the performance of superconducting magnetic energy storage device charging!

Obviously, the current fusion reactor in Mars City is not powerful enough, otherwise such a situation would not have occurred.

This is no way.

When it was originally designed, the power of the fusion reactor in Mars City was not even comparable to the fusion reactor inside the Luanniao starship.

"Professor, the charging has been completed!" Zero Yong said in a flat voice, "The energy storage goal has been achieved!"

This is still just the first step.

For the electromagnetic gun, the most test of the performance of the energy storage device is actually the power of the released energy!

"Zero, start releasing energy!"

The moment the voice fell, the curve in the holographic image jumped up instantly, and then fell back quickly.

On the smooth curve, a sharp peak piercing the sky appeared!

"Professor, the release of energy has been completed."

"The instantaneous power has reached the standard!"

Chapter 220 Launch Failed?

"The power reaches the standard!"

Looking at the few Chinese characters displayed on the holographic image, Lu Yongchang and Professor Yevgeny on the side showed gratified smiles on their faces.

The biggest difficulty of the electromagnetic gun has been solved!

"Professor, there is bad news."

Just when the two were delighted, Zero's voice sounded in time and poured a basin of ice water on them.

"...you say it." The smile on Lu Yongchang's face suddenly faded.

The holographic image zooms in instantly.

Then, a spectacular picture appeared in front of the two of them.

On the ground outside Mars City, there is a huge electromagnetic railgun quietly placed.

The key part of the electromagnetic railgun, the gun barrel, reached more than [-] meters in length.

There are two shiny, parallel rails inside the barrel.

That's the most important part of the electromagnetic railgun, the accelerated orbit.

The interior of the acceleration track is filled with densely packed superconducting coils.

At the end of the barrel, there is a huge base.

Inside the base, the most important superconducting magnetic energy storage device and other equipment are installed.

"Professor, this is the simulation screen of the electromagnetic rail gun designed by Professor Yevgeny." Zero's voice of explanation sounded.

Lu Yongchang nodded lightly, with a bit of puzzlement in his eyes: "Is there any problem?"

In his opinion, this electromagnetic railgun is perfect in both its appearance and the structural design of its various parts.

"The problem is big." In order to attract Lu Yongchang's attention, Zero specially simulated a heavy tone, "Next, I will conduct a real-time simulation of the launch screen."

The voice fell, and a projectile fell into the launch port.

"Professor, the material of the projectile is tungsten alloy according to the design plan." Zero returned to a flat tone again, "Now, let me 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 charged with enough electric energy for one launch!

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

It happened by accident!

In the next instant, the middle section of the barrel exploded!

Metal substances in a molten state slowly flowed out from the broken barrel.

The simulated picture is very real, coupled with the display effect of the holographic image, even if there is no sound, the two have an immersive feeling.

The moment the barrel exploded, Lu Yongchang suddenly suffocated and subconsciously held his breath.

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

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

He said in a deep voice, "Evgeny, there is something wrong with the projectile."

"Bullet?" Yevgeny hadn't broken free from the scene where the gun barrel exploded just now, his eyes were filled with panic, "How could the bullet..."

Halfway through the conversation, Yevgeny also realized the problem.

He swallowed slightly, and said word by word in not-so-standard Mandarin, "You mean... this projectile melted under the strong current?"

Lu Yongchang nodded with a wry smile.

Even he subconsciously ignored a problem.

The first few simulation calculations were all based on ideal conditions.

"While the coils and various components are made of superconducting materials, we missed one point."

"The projectile of the electromagnetic railgun is the connection point of the two tracks, and it has resistance." Speaking of this, Lu Yongchang shook his head helplessly, "Zero, re-simulate the failed scene just now."

In the holographic image, it was like going back in time, and the screen returned to the second before the launch again.

"Zero, change the perspective and show the status of the projectile in real time."

The picture in the holographic image changes instantly.

A projectile with a silver-white metallic luster lay quietly between the two sections of acceleration orbit, connecting the two independent sections of orbit together to form a complete closed loop.

"Zero, slow down the entire launch process."

"Got it, Professor."

The screen changes again.

In order to visually display the entire launch process, Zero specially marked the running direction of the current.

The current passes through the acceleration rail on the left, passes through the metal projectile, and flows into another section of the acceleration rail.

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

Then, under the action of the electromagnetic field, the electrified projectile rushes forward along the guide rail under the action of Ampere's force!

During this process, the surface of the projectile became more and more red until it turned into a ball of molten metal!

Immediately afterwards, the scene of the barrel bursting reappeared in front of the two of them.

"..."

A silence.

Lu Yongchang and Yevgeny silently looked at the broken barrel in front of them.

……

"Professor, we failed..."

More than ten minutes later, Yevgeny sat on the seat of the laboratory and said dejectedly: "Not only the projectiles, our guide rails will also face extremely serious ablation problems under high-speed launch."

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

Not bad.

Even if the projectile can withstand the extremely powerful current, at a moving speed of 5000 km/s, the guide rail of the electromagnetic railgun will be subjected to extremely severe ablation!

According to Zero's simulation, even if there is no problem with the projectile, the acceleration rail of the electromagnetic railgun will be on the verge of being scrapped after firing the railgun ten times.

This is obviously unacceptable to Lu Yongchang.

It can't be that the interstellar war just started, we need to call a timeout to change the barrel, right?

This must not be laughed to death by the Proxima Centauri?

"Change the plan."

Lu Yongchang was silent for a moment, then sighed lightly and said: "The electromagnetic rail gun doesn't seem to work."

"We've got to go the other way."

"Try a coilgun."

Compared with electromagnetic railguns, the principle of electromagnetic coilguns is more complicated.

Unlike railguns, electromagnetic coilguns are equipment that accelerate magnetic materials to extremely high speeds through a projection accelerator composed of countless coils.

Although both belong to electromagnetic guns, electromagnetic coil guns contain higher technological content.

"A coil gun?"

Yevgeny frowned, stood up and thought.

Yes, coilguns can indeed avoid a series of accidents that occur on railguns.

Coilgun projectiles are made of magnetic material that does not come into contact with the barrel.

To be precise, the projectile of the electromagnetic coil gun is suspended in the barrel under the constraint of the magnetic field.

This directly solves the ablation problem of the barrel.

There is no current passing through the projectile and no heat is generated.

Fundamentally solved the bombing problem of the rail gun.

It's just... there are advantages and disadvantages.

Compared with electromagnetic railguns, electromagnetic coilguns must have their disadvantages.

Due to structural complexity and problems such as coil synchronization, the stability of the projectile launch will not be very good.

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