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

Lu Yongchang nodded thoughtfully.

"Mach 10...that's a bit slow."

The exit speed of 3400m/s...in space, it is just like a snail.

It can't even match the speed of the Luanniao starship!

"Professor, how much do you think we should aim for?" Yevgeny's voice interrupted Lu Yongchang's meditation.

"The target... the exit speed must be at least 5000km/s."

"..."

In the laboratory, everything was quiet.

All the researchers, including Yevgeny, stared at Lu Yongchang with wide eyes.

"5000km/s initial velocity?!" Yevgeny breathed heavily, looking at Lu Yongchang with a slightly flushed face, "Professor Lu, do you think this is possible?!"

Lu Yongchang was silent for a while.

He did not answer Yevgeny's words directly, but shouted at the camera on the side.

"Zero, according to the ideal situation, how much can the fusion reactor on the Luanniao starship increase the initial velocity of the electromagnetic gun?"

The holographic image unfolds instantly.

A string of data flashed across it.

Zero responded in a flat tone: "Professor, according to calculations, if starship power and various problems are not considered, it can accelerate a standard projectile to 2 km/s."

"Here." Lu Yongchang smiled faintly, "Look, 5000 km/s is not too low."

Yevgeny swallowed slightly as he watched the calculation process on the hologram.

"Professor, you are even crazier than I imagined!"

As he spoke, Yevgeny looked at Lu Yongchang with admiration in his eyes.

According to Zero's simulation, to achieve such an effect, there is basically only one function left in the entire Luanniao starship.

fire!

As a faithful believer in caliber is justice, Yevgeny swears that even he has never thought of such an exaggerated thing!

Lu Yongchang cheerfully accepted Yevgeny's 'praise': "Calm down, the Luanniao starship is still too small."

"If you magnify the size of the starship ten times, you may not feel exaggerated."

Yevgeny looked at Lu Yongchang with a numb expression.

Is this what people say?

He rubbed his temples with a headache and skipped the topic: "However, even if the energy problem is solved, we still don't have the energy storage equipment to support its launch."

This is the biggest problem limiting electromagnetic guns.

Energy storage, needless to say, what the electromagnetic gun needs is extremely fast energy discharge and recharge technology.

The energy release problem is related to the power of the electromagnetic gun.

What the electromagnetic gun needs is instantaneous power, and the energy storage device needs to release its stored electric energy in a very short time.

The problem of charging is related to the continuous combat capability of the electromagnetic gun.

You can't need a few hours of buffer time after firing a shell, right?

Of course, under the premise of fast charging and discharging energy, there is another hard requirement for energy storage equipment.

The capacity of the energy storage device.

Wanting to take into account these three requirements... Yevgeny can be sure that the current human beings have absolutely not mastered such an exaggerated energy storage technology.

Faced with Yevgeny's doubts, Lu Yongchang nodded calmly: "Don't worry, don't worry about energy storage technology."

"I already have a solution."

"All you have to do is complete the basic structure of the electromagnetic gun."

Yevgeny: "...???"

At this moment, his eyes were full of doubts about himself.

When did he take over such an easy research and development task?

As long as the basic structure of the electromagnetic gun is completed, this is the end?

He took a deep breath and nodded silently.

"Professor, I listen to you."

Lv Yongchang smiled and patted the muscular back of the Su man in front of him: "Come on."

"I hope to see results within half a month."

After speaking, he turned around and walked quickly towards his office.

He needs to realize the inspiration that flashed in his mind!

Yevgeny's face froze: "..."

Now, he decided to take back his earlier exclamation.

This tm is a task that humans can complete? !

"Wait, wait, professor, half a month? Did you say the wrong time?!"

Yevgeny followed Lu Yongchang hurriedly and asked.

Lu Yongchang naturally did not stop his steps, but just waved his hands and left a word.

"Believe in yourself, you can do it."

Seeing Lu Yongchang's disappearing figure, the corners of Yevgeny's eyes twitched violently twice.

"Calm down, Professor Yevgeny." A former Xia State researcher stepped forward and patted Yevgeny's shoulder reassuringly, "Just get used to it."

"Professor Lu's scientific research tasks have always been like this."

"For the past half month, let's sleep less."

Yevgeny turned his head and looked numbly at the smiling researchers.

"Are you always like this?"

Several yellow-skinned scientific researchers nodded with smiles on their faces, and said in unison: "Of course!"

Yevgeny's complexion became increasingly gloomy.

Chapter 219 Superconducting Magnetic Energy Storage Device

Lu Yongchang, who returned to the office, picked up the pen on the table, took out a brand new A4 paper, and began to write and draw.

It didn't take much time, and a standard sketch appeared on paper.

The camera on the side turned the angle and carefully "observed" the pattern on the paper.

"Professor, do you want to use a superconducting magnetic energy storage device?"

The moment Lu Yongchang put down his pen, Ling's voice of inquiry sounded.

Hearing Ling's question, Lu Yongchang's eyes showed some surprise.

This should be the first time that Zero has actively speculated on what he drew on the drawings.

"Zero, do you know this?"

As soon as he finished speaking, a somewhat self-deprecating smile appeared on Lu Yongchang's face.

Also, how could Zero not recognize this thing.

At present, the data of all human beings is basically stored in Zero. This kind of energy storage facility that has been proposed for a long time is naturally in its database.

"Yes, Professor, there is information about it in the database." Zero didn't know what Lu Yongchang was thinking, and replied in a straightforward manner.

Superconducting Magnetic Energy Storage Device

The so-called superconducting magnetic energy storage device, the principle is very simple, it is a coil made of superconducting material.

The electrical grid feeds current into it, creating a magnetic field in the coil, which stores energy.

And because of the characteristics of the superconducting coil, the current will always exist in the closed coil.

Release the current therein until needed.

Such a cycle constitutes an energy storage device with a simple principle.

Compared with ordinary energy storage devices, superconducting magnetic energy storage devices have many advantages.

First, it can store energy without loss for a long time.

Second, it is what Lu Yongchang needs, fast response speed, strong charging and discharging performance!

Combining the above two points, it can be said that this is the perfect electromagnetic gun energy storage device!

As for why the previous electromagnetic guns did not use this device, the reason is naturally very simple.

In the absence of room-temperature superconducting materials, superconducting magnetic energy storage equipment is expensive and consumes a lot, which can be said to be not worth the candle.

Lv Yongchang withdrew the thoughts in his mind, relaxed his body slightly, lay on his back on the office chair, and said softly.

"Since you have information in your database, let me simulate how large-scale superconducting magnetic energy storage equipment can meet the needs of electromagnetic guns."

"Got it, Professor!"

Zero's voice fell, and the holographic image flickered, illuminating the somewhat dim room.

……

half a month later.

Yevgeny, staring at a pair of dark circles, knocked on the door of Lu Yongchang's office.

"professor……"

Yevgeny shouted in an extremely feeble voice.

"Click."

There was a sound of the door lock twisting, and the door opened automatically.

"Fuck!" Seeing Yevgeny outside the door, Lu Yongchang let out a soul-stirring sigh, "Professor Yevgeny, what's wrong with you?"

Hearing Lu Yongchang's inquiry, Yevgeny twitched the corner of his mouth "weakly" and showed a forced smile: "No, nothing."

"It's just half a month of extra work, it's okay..."

"By the way, professor, we have completed the basic structure of the electromagnetic gun for the task you gave us."

Seeing the exaggerated acting skills, the corners of Lu Yongchang's eyes twitched.

Lu Yongchang sighed softly, and stood up from his seat with a look of "concern" on his face: "Unfortunately, I wanted you to go with me to test the performance of the energy storage equipment, but now it seems that you need a vacation. .”

"That's it, Professor Yevgeny, you go back to rest first, and I will arrange for people to continue the research and development of the electromagnetic gun in the second half."

Yevgeny stood there with a confused face: "???"

This? !

Energy storage device complete? !

In just one sentence, he was completely sent away? !

What a joke!

If he can't see the scene where the electromagnetic gun fires, he will die with regret!

He quickly stretched out his generous palm and rubbed his cheeks vigorously: "Professor Lu! You misunderstood me!"

"I think I'm in good spirits now and don't need to rest at all!"

Lu Yongchang's eyes were full of smiles.

Because the research and development progress perfectly met expectations, Lu Yongchang, who was in a good mood, joked to Yevgeny: "Really?"

"Don't care about my opinion, if you are tired..."

"No, no, no!" Yevgeny spoke his mother tongue anxiously, "Professor, trust me, I'm definitely not tired!"
