After sending Weibo, Liu Feng still has some unfinished business.

Although Professor Xu Zhixiong's idea seems crazy, if you think about it carefully, you will find that it is actually not unfeasible.

Aside from the unreliable idea of using an atomic bomb, at least, the sci-fi idea of propelling a spacecraft with the help of powerful pulse energy provided him with a lot of novel ideas for studying antimatter engines.

That's right, the price of the atomic bomb is expensive, and it will cause a certain amount of nuclear pollution, which is restricted by all countries in the world, but the antimatter bomb will not, although, in a sense, antimatter itself is a kind of nuclear energy, and the energy conversion method of the two is roughly the same, but antimatter has no nuclear pollution, and compared with the atomic bomb, it is small in size, light in weight, and large in energy release, the key is that the price is also very cheap!

Therefore, if the route of "high-energy particle reversing" is too difficult to study antimatter engines, the route of "pulsed energy propulsion" is not a solution.

Regardless of anything else, he casually opened the computer on the table, and according to Professor Xu's ideas, Liu Feng couldn't wait to look up papers related to this aspect on the computer......

In fact, pulse energy is not completely science fiction, at least NASA, the Mao Bear Space Agency and even China itself have done a lot of research in this area, and in journals such as Arixv, you can even find relevant papers, but no one is like Professor Xu, directly launching an atomic bomb as energy.

No one dared to say what was absolutely about the future, not even the world's most eminent scholars, to make absolutely impossible assertions about the unknown in science and technology, even if these technologies seemed strange or even absurd at the time.

But in any case, using the pulse energy of an atomic bomb explosion for something as distant as a spaceship is definitely not a topic of our time.

It's just that you can't use atomic bombs, you can't use other energy without trying it, you can't use it to power large spaceships, and you can't use it in other things if you don't try it......

After swiping many papers from the computer, Liu Feng finished brushing one and then another.

Until the night deepened and the bright moon hung high, this guy was like a demon, and he kept brushing unswervingly.

On the way, Miss Zhuo Tingting came to see him several times, but she didn't interrupt his train of thought;

Because she knew that when Liu Feng appeared in this state, it must be the brains of this great scientist who were doing a great collision of inspiration, and if he accidentally disrupted one of his ideas, to be honest, it would be really 'sinful'.

Although she was very worried about Liu Feng's body, she couldn't bother, so she could only accompany him quietly after doing her own thing, and this was one of the reasons why she was able to be Liu Feng's other half.

The dinner was heated several times, and several teas were added on the table, but in the end, the young lady still couldn't hold on and fell asleep on the sofa next to Liu Feng......

As more and more papers were watched, the ideas in Liu Feng's mind were gradually taking shape.

When he, as the chief engineer of antimatter, swiped a paper called "Overview of Hypersonic Weapons Research" from the secret unit, the whole person was like an enlightenment, and it was instantly transparent.

Suddenly, the creature burst out laughing, "Hahaha! Yes, even if the method of propelling a spaceship with pulsed energy seems a bit frustrated, it is definitely perfect for a small flying machine!

To tell the truth, the antimatter engine he and Jin Donghan are developing now relies on the powerful reaction force of the high-energy particles generated after the annihilation of the positive and antimatter to be emitted from the tail nozzle of the engine, which becomes the thrust of the space creation, however, it is obvious that the antimatter engine made in this way must be very large.

Because these energetic particles are very fast, moving almost 94% of the speed of light, and the survival time is quite short, the normal half-life is 28 nanoseconds, and even if they move at 94% of the speed of light, the half-life can only be extended to 70 nanoseconds.

In such a short period of time, these energetic particles can advance at least 24 meters, and combined with the time it takes for a strong magnetic field to confine integration, this means that the distance from the combustion chamber of the antimatter engine to the vent also needs to be at least 72 meters long!

If you add the space required by a spaceship, then the length of a spaceship can be imagined.

From the point of design, Liu Feng and Jin Donghan never had the luxury of expecting this kind of spacecraft to be small, not to mention, it has great benefits, just like the sea ship is getting bigger and bigger, at least in terms of energy utilization efficiency and relative cost.

However, like aircraft carriers, when this kind of spaceship performs interstellar missions in the future, it is impossible for the spacecraft itself to do everything by itself, and to a large extent, I am afraid that it will have to rely on the small aircraft carried on the spacecraft to carry out it;

And these small aircraft cannot be powered by such antimatter engines, but can only be powered by other powers, such as chemical power, electric propulsion, solar energy or nuclear energy.

However, the small aircraft that rely on these powers can never be compared with the mothership in terms of speed, and as an obsessive-compulsive patient, Liu Feng can't imagine such a scene at all:

Someday in the future, a space carrier sets off from its home port at full speed to meet the enemy.

"01, 01, enemy forces found, enemy forces found, target 0.001236 light years!"

"01 received, 01 received! J-222 fighter, dispatch!"

"Understood!"

"Whoosh ......"

As a result, a group of J-222 fighters ran farther and farther,

It's just that he watched the mothership gallop in the direction of the enemy, and he could only eat dust behind his ass......

At this time, if the power of these small aircraft is replaced by pulsed energy engines, then the result is completely different...... At the very least, in terms of instantaneous thrust, the thrust formed by the pulsed energy is much greater than the reaction force of the energetic particles.

Thinking of this, Liu Feng was already so excited that he couldn't help himself.

Because unconsciously, he is likely to solve another problem faced by the future interstellar era - to find a space fighter that can be matched with the space carrier!

Of course, what kind of space fighter or the like, at present, it seems that it is still quite far away and even very likely to be unnecessary, however, in addition to space fighters, this kind of high-energy pulse energy engine can be used in the current hypersonic weapons!

The pen in his hand is like flying, if there is divine help.

After an unknown period of time, a sketch took shape.

Looking at his masterpiece with satisfaction, this guy casually picked up the mobile phone on the table and dialed out......

The other side.

It's the middle of the night.

It was already one or two o'clock in the morning.

Academician Kim Dong-han had fallen asleep.

It's just that because he usually works overtime to about one point, he just fell asleep at this time.

"The night gave me black eyes......"

In the daze, a crisp mobile phone ringtone came into my ears.

Academician Jin, who finally fell asleep, suddenly felt a burst of fire, after all, anyone who was harassed at this time would not feel comfortable.

Unable to endure the scolding words, just as Academician Jin took the mobile phone and was about to scold the other party, he was stunned when he saw the caller displayed on the mobile phone.

Good guy, it turned out to be Liu Feng, Professor Liu!

Jin Donghan was stunned.

They've never seemed to have reached out since they exchanged phone numbers, right?

After all, everything is communicated through a dedicated email or video on the computer.

The point is, it's so late at night, this guy hasn't slept yet, is there something very important?

I didn't dare to slack off, and hurriedly dialed the answer button.

"Hey, Liu Feng?"

"Hahaha, Academician Jin, why haven't you slept yet?" Liu Feng on the other side was as excited as a child, no, compared to Academician Jin, this guy seems to be really a child?

Said happily,

"Guess what I just found?"

“……”

Yet~Haven~Sleep~Sleep~?

My Professor Liu, Lao Tzu was obviously woken up by you!

When is it?

Jin Donghan, who heard these words, was speechless for a while, but he vaguely admired Liu Feng even more.

Look at people, they are already standing at the top of the pyramid of honor, and they are still working so hard, and they are still doing research at such a late hour, no wonder they can succeed.

The dissatisfaction in his chest immediately dissipated, Jin Donghan straightened his mind, and said with a serious face: "Professor Liu, have you made any important discoveries?"

"I can't talk about important discoveries, but they can also open up a new development idea for our antimatter engine. ”

I have to say that the joy of being able to find a like-minded person to share his research is no less than pretending to be a slap in the face, so Liu Feng nodded with satisfaction and continued,

"I can't tell you exactly what it is on the phone, I'll send the information I just sorted out and a sketch to your mailbox, let's open a video and add it up. ”

"Forehead ......"

Jin Donghan wanted to say something, but Liu Feng on the other side had already hung up the phone.

Shook his head helplessly, but he didn't care at all, who called someone the chief teacher?

Hurriedly came to the desk to turn on the computer and entered the password.

Then while communicating with Liu Feng on the video, he checked the email sent to him just now.

Find the information Liu Feng gave him from the email, download it directly, and open it.

Several papers came to mind - "Overview of Hypersonic Weapons Research", "Mechanism of Bursting of Pulsed Energy", "How Scramjet Engines Work", ......

Confused, I skimmed through it briefly, still not understanding what the hell this guy was up to, so I could only carefully look at the last manuscript like a dog's crawl.

I have to say, the words are really ugly.

I also have to say that in the research of power machinery, Jin Donghan really deserves to be a man standing at the top of China.

After reading it briefly, he already knew what Liu Feng was studying.

It turned out to be a pulsed energy engine fueled by the annihilation of positive and antimatter!

His expression immediately became serious, and he carefully browsed it several times;

After a while, glancing at Liu Feng, who was waiting for dinner at the other end of the video, Academician Jin sighed:

"I have to say, you guy is a demon!"

"Hey, hey, how about it, Academician Jin, let's make this sketch feasible, right?"

To be honest, fiddling with the design of the engine in front of Academician Jin, Liu Feng always felt a feeling of getting an axe, although he admitted that he was a genius, but in this aspect of the design, after all, it was Academician Jin who introduced him to get started, and even to a certain extent, Academician Jin Donghan was his mentor, but there was no formal entry, and there was no real name.

Therefore, Liu Feng still respects Academician Jin quite a lot, just like Boss Wang and Boss Duan, but it is more of a complex relationship between teachers and friends, superiors and subordinates.

Jin Donghan nodded: "Well, although it is quite rough overall, the basic design concepts and principles are clearly marked, and the general structure has not been left behind, it seems that you have also put your heart into it." By the way, how long have you been working on this blueprint?"

Looking at the time displayed on the computer, Liu Feng smiled embarrassedly: "Probably, it took a night......

One

At night

Let's do it!

Kim Donghan: "......"

He almost knelt down for Liu Feng!

This guy, I'm afraid, is not just a demon, he is simply possessed by God, no, he is simply God!

The earth really can't stop your rhythm, so you better hurry up to the sky!

"What do you think, if we give a grade for the undergraduate graduation defense, can we be excellent?"

was stunned for a long time, and when he saw Liu Feng's solemn "cheapness", Jin Donghan really wanted to slap it along the network cable!

Still graduated from a bachelor's degree, who is Hanqi?

I'm afraid it's hard for even a PhD student to design this thing, right?

"Ahem, there is no problem with the principle and design structure, but it is difficult to say whether it can be done and whether the cost can be afforded. ”

Jin Donghan coughed softly, and said seriously,

"I looked at what you said about Xu Zhixiong's idea of using a nuclear explosion to propel a spacecraft, and in addition to absorbing the energy of the atomic bomb explosion, he also used this energy to evaporate a solid disc made of polyethylene plastic and convert it into a high-heat plasma slurry to form a propulsive force. ”

However, unlike the energy after the atomic bomb explosion, most of which is instantaneous heat radiation, only a small part of the energy generated by the antimatter bomb will be converted into heat energy in an instant, and the vast majority is converted into high-energy γ rays with high-energy mesons; ”

"So we can use the same principle, but in a different way. ”

Professor Liu Da actually has some negligence in consideration, and I have to say that this feeling is ......

Speaking of this, Academician Jin Donghan smiled incomprehensibly, and subconsciously wanted to hold the teacup with his right hand.

It's a pity that the teacup he usually drinks is put on the bedside table, so he can only awkwardly touch the stubble under the corner of his mouth.

However, Liu Feng's focus is not on this.

In the video, I saw this guy sighing, listening to Academician Jin's teachings with a serious expression, and nodding from time to time:

“…… That's right, I was negligent, and I thought about it differently...... So how do we do that?"

"How to do it, hehe," Jin Donghan said with a pleasant smile on his face, and said in a thoughtful tone, "Just leave it to your old power engineering homework, if you can solve such a problem, it will prove that you have the skills of a master in power engineering, as for now...... Hurry up and go to bed!"

Liu Feng: "......"
