Chapter 220 Launch failed?

"Power reaches the standard!"

Looking at the Chinese characters displayed on the holographic image, Lv Yongchang and Professor Yevgeny beside him smiled with relief.

The biggest difficulty of the electromagnetic gun has been solved!

"Professor, there is a bad news."

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

"...You say." The smile on Lv Yongchang's face suddenly converged.

The holographic image was instantly enlarged.

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

On the ground outside Mars City, a huge electromagnetic rail gun was quietly placed.

The key part of the electromagnetic rail gun, the barrel, is more than 50 meters long.

There are two shiny, parallel rails inside the barrel.

That is the most important part of the electromagnetic rail gun, the acceleration track.

The inside of the acceleration track is filled with dense superconducting coils.

At the tail of the barrel is a huge base.

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

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

Lv Yongchang nodded gently, with some confusion in his eyes: "Is there any problem?"

In his opinion, this electromagnetic railgun, whether in appearance or structural design of each part, is perfect.

"There is a big problem." In order to attract Lv Yongchang's attention, Zero specially simulated a heavy tone, "Next, I will simulate the launch screen in real time."

As soon as the voice fell, a projectile fell into the launch port.

"Professor, the projectile material uses tungsten alloy according to the design plan." Zero returned to a calm tone again, "Now, let me simulate the launch screen."

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

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

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

An accident occurred!

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

The molten metal slowly flowed out of the broken barrel.

The simulated image was very real, and coupled with the display effect of the holographic image, even without sound, it made the two feel as if they were there.

At the moment the barrel exploded, Lv Yongchang's breath suddenly choked and he subconsciously held his breath.

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

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

He said in a deep voice: "Evgeny, there is a problem with the projectile."

"Projectile?" Yevgeny had not yet escaped from the scene of the barrel exploding just now, and his eyes were filled with panic, "How could the projectile..."

Halfway through his words, Yevgeny also realized the problem.

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

Lv Yongchang smiled bitterly and nodded.

Even he subconsciously overlooked a problem.

The first few simulations were all based on ideal conditions.

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

"As the connecting point between the two tracks, the projectile of the electromagnetic railgun has resistance." At this point, Lv Yongchang shook his head helplessly, "Zero, simulate the failed scene again."

In the holographic image, as if time was going backwards, the picture returned to one second before the launch.

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

The picture in the holographic image changed instantly.

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

"Zero, slow down the entire launch process."

"Got it, professor."

The picture changed again.

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

The current passed through the acceleration track on the left, through the metal projectile, and flowed into the other 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 rushed forward along the rail under the action of the Ampere force!

In this process, the surface of the projectile became redder and redder until it turned into a ball of molten metal liquid!

Then, the scene of the barrel bursting reappeared in front of the two people.

"..."

There was silence.

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

...

"Professor, we failed..."

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

Lv Yongchang did not speak, but looked at the holographic image in front of him with a serious expression.

Not bad.

Even if the projectile can withstand the extremely strong current, at a speed of 5000 km/s, the rail of the electromagnetic railgun will be severely ablated!

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 scrap after firing ten electromagnetic guns.

This is obviously unacceptable to Lv Yongchang.

We can't call a pause to change the barrel just as the interstellar war begins, right?

Wouldn't the Proxima Centauri laugh at this?

"Change the plan."

Lv Yongchang was silent for a moment, sighed softly and said: "It seems that the electromagnetic railgun is not feasible."

"We have to change direction."

"Try the electromagnetic coil gun."

Compared with the electromagnetic railgun, the principle of the electromagnetic coil gun is more complicated.

Unlike the railgun, the electromagnetic coil gun is a projection accelerator composed of countless coils, which accelerates magnetic materials to extremely high speeds.

Although both are electromagnetic guns, the electromagnetic coil gun contains higher technological content.

"Coil gun?"

Yevgeny frowned and stood up to think.

Yes, the coil gun can indeed avoid a series of accidents that occurred on the railgun.

The projectile of the electromagnetic coil gun is made of magnetic material, and it does not contact 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 problem of barrel ablation.

No current passes through the projectile, and no heat is generated.

This fundamentally solves the problem of railgun barrel explosion.

However... there are advantages and disadvantages.

Compared with electromagnetic railguns, electromagnetic coil guns must have their disadvantages.

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

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