It is absolutely impossible to dismount.

Not to mention that they had already announced the news to the world, the elders even invited the leaders of several friendly countries to attend the aircraft carrier handover ceremony, and the test launch of electromagnetic weapons on the ship was another highlight of the aircraft carrier handover!

Therefore, without a convincing reason, it is absolutely impossible for the electromagnetic cannon to be canceled, and they can't afford to lose this face!

But what to do?

Academician Ma sighed: "Professor Liu, so far, you comrades who have been in the war can only play a role, what do you think?"

Liu Feng seemed to understand what Academician Ma meant: "This ...... It's not good, people come all the way to see the legendary electromagnetic weapon comparable to a small atomic bomb, how can we fool people?"

Academician Ma pursed his lips, thinking to himself that you guy was originally a big fool, so far, I don't know how many people have been stimulated by your kid, and they are still studying controlled nuclear fusion!

"Why don't you come up with an idea? I'll listen to you!"

"Ahem," Liu Feng could only cough helplessly, and had to agree with Academician Ma's opinion, "What, let me ask the comrades who are in the war and see if they take over?"

……

In mid-March, the grass grows and the warbler flies.

Just one day before the test of the electromagnetic catapult began, Liu Feng came to the Naval University of Engineering in advance at the request of Academician Ma, followed by three apprentices.

This time, it was President Lian Hanfei of the Naval Engineering University who took the initiative to greet him.

Like Academician Ma, President Lian also belongs to the academician of the Chinese Academy of Engineering, and is also a senator at the last Diaoyutai State Guesthouse meeting, with the rank of major general.

The two had some exchanges when they were at the State Guesthouse, and they can be regarded as acquainted.

"Welcome, Professor Liu! I heard the magpie chirping early this morning, and I knew it was you. ”

With hearty laughter, Principal Lian stretched out his right hand, shook Liu Feng in a friendly manner, and then looked at the several apprentices next to him,

"New face, this is your student?"

"That's right, Zhou Yue, Fei Xiujin, and Du Hong," Liu Feng pointed to the three apprentices in turn with his right hand, and introduced with a smile, "My newly accepted graduate students, bring them out to meet the market." ”

"Welcome, Professor Liu's high foot is also an honor for our school to come to Marine University of Technology. Principal Lian took the initiative to stretch out his hand and shook hands with a smile on his face.

"Academician Lian, hello!"

The three of them were a little flattered, if it was the past, how could they have this opportunity to have close contact with an academician boss?

This is all due to the fact that they have a mentor who is awesome~!

The eyes that looked at Liu Feng became more and more respectful.

The three of them did not dare to slack off, and respectfully stepped forward to shake hands with Principal Lian.

After a few brief words of greeting, Principal Lian glanced at Liu Feng, turned around and instructed the assistant beside him:

"Wang Feng, you take Professor Liu's Gaozu to visit our school first, and I have something to discuss with Professor Liu. ”

"Three, please come with me......"

Facing the eyes of the three apprentices for verification, Liu Feng nodded affirmatively.

Before coming to the University of Technology, Academician Ma had already communicated with Liu Feng in advance, so he didn't feel abrupt at this moment.

After 'sending' the 'oil bottle' around them, the two talked while walking towards the School of Electrical Engineering.

"Professor Liu, I don't know much about this antimatter, but the professors in our school agree that if you take out your antimatter large-scale production technology, at least another dynamite award will definitely not be able to run. ”

"Where," Liu Feng said modestly, "you really think too highly of me." ”

"What is not to be looked up to, besides you, who in our country has won the dynamite award? Who else is more qualified for the dynamite award?"

Principal Lian smiled, and after a pause, he changed to a serious tone and said,

"In fact, the last time we listened to your views at the Diaoyutai State Guesthouse, we have been thinking about how to keep pace with the times and carry out some reform of the school to cope with the development of the situation. After all, our school belongs to the navy, and many disciplines are related to the navy, and once the interstellar age comes, most of the majors will lose their research significance...... It's just that we really don't have any research on antimatter, so I want to ask you what do you think we should do in this direction?"

Liu Feng was slightly stunned, this question is very big!

It's just that he fully understands what the principal means, and as the culprit who led to the need for 'reform' in other schools, he can't shirk it.

After thinking about Principal Lian's question for a few seconds, he spoke:

"I don't know exactly how to reform, but I have some superficial views on the general direction of reform. ”

"Speak, please. Principal Lian stretched out his hand.

Seeing that the other party looked deaf, Liu Feng paused and continued,

"Personally, I think that in fact, there are many aspects of the Navy and the future Space Force that are exactly the same, and there is no need to make major adjustments to the relevant specialties such as military command and logistics arrangements. ”

Indeed, antimatter technology has had a subversive impact on the development of the Navy in the future, but for the Naval University of Engineering, in addition to technology, the impact of other professional categories is not as great as imagined, military command and logistics, always advancing with the times, and will not be abandoned because of the development of technology, even if there is no Navy in the future, but the Naval University of Engineering can also be transformed into a Space Force Engineering University.

At this point, even the headmaster nodded.

"From a technical point of view, the most far-reaching impact of antimatter technology on our offshore engineering is mainly in power engineering and ship engineering.

Conventional naval ships are not the same as spaceships based on antimatter power, and the resulting ship system layout is completely different.

The largest platform in the Navy is nothing more than an aircraft carrier, however, even an aircraft carrier, limited by a series of factors such as power, is at most only a few football fields in size, and the crew is only a few thousand;

And the spaceships of the future will not be so much spaceships as they will develop into space fortresses......"

Hearing this, Academician Lian frowned and showed a surprised expression,

"Professor Liu, do you mean that the future development trend of spacecraft will be based on the majority?"

"It's not that bigger is better, but it's bound to become bigger than an aircraft carrier!"

Liu Feng shook his head and explained seriously,

"With current antimatter technology, we can't make a spaceship 'short and short', and in terms of economic effects, the bigger the ship, the more ......economical it is."

Completely different from traditional chemically powered rockets, antimatter engines must have a tail nozzle hundreds or even thousands of meters long in order to form a strong anti-thrust;

Because the Particle Beam Core Engine performs the annihilation of positive and antimatter directly one-on-one, and then uses a magnetic field to control the charged mesons and eject them directly from the vent, the ship must be built very long because these mesons are moving at close to the speed of light......

And in terms of efficiency, the bigger the thing, the more energy saving, which is consistent with the larger transport ships built on the planet.

In the consciousness of Academician Lian and others, spaceships in the future interstellar era should generally be like those in movies and TV series, with size and volume like ordinary airplanes, and compared with the warships of the Navy, they must be far inferior in volume and tonnage.

However, Liu Feng's meaning turned out to be completely opposite to what they expected!

After explaining, I have to admit that people are professionals!

At this moment, President Lian was very glad that he was able to know this Professor Liu and had the opportunity to listen to his opinions, otherwise, the reform they decided on with a pat on the head might have become a laughing stock......

In fact, Liu Feng did not want to build a future spaceship the size of an airplane on the earth, after all, the smaller the thing, the more flexible it is, and it can meet the needs of various special conditions.

It's just that there is often a certain distance between the ideal and the reality, and until now, even the 'spaceship' powered by chemical fuel has a length of tens or hundreds of meters, and the reason why everyone has a relatively 'small' illusion is completely because they are confused by what they see in front of them!

After all, the return capsule or the 'space station' that can be used is so big that it completely ignores that the rocket used to carry these things is the bulk of the entire 'spaceship'......

But Liu Feng feels that this day will come in the future, and it is only a matter of time.

For example, an aerospace carrier similar to an aircraft carrier, the entire large platform can be powered by antimatter, and a small spacecraft like an airplane can be completely replaced with other energy sources as power, which is also the fundamental reason why he believes that the future J-20 and other earth fighters will be completely useless.

"It's really better to listen to your words than to read a book for ten years. Principal Lian sighed with emotion.

Liu Feng gave them advice to the University of Offshore Engineering, and I don't know how much time they saved in groping!

After a pause, he said embarrassedly:

"Professor Liu, I have another reluctant request. ”

Liu Feng said curiously: "You say." ”

"I would like to ask you to give us a lecture on the future of antimatter technology and the future interstellar era, what should we do at the University of Offshore Technology......"

Liu Feng was stunned, but nodded very happily: "No problem, this is my duty, when exactly?"

"You think it's 7 o'clock tonight?"

"No problem at 7 o'clock!"

……

So, after dinner, Liu Feng returned to the accommodation room, changed his clothes, and went out again.

The Naval University of Engineering itself belongs to the category of the military, and its secrecy naturally goes without saying, Liu Feng does not have to worry about leaking secrets at all, not to mention, most of the subjects of this class are experts who attended the Diaoyutai State Guesthouse last time, and a small number of people are also senior professors in the military system, and they have also undergone strict political review.

Although these people are all engineering professors and may be different from Liu Feng in their professional fields, this does not affect anything, because Liu Feng himself is an all-rounder, and it is precisely because of this that he can help Academician Ma Mingwei improve the manufacture of electromagnetic catapults.

Although it was a lecture that he had agreed to on an ad hoc basis, he had not made much preparation before that, but for Liu Feng, there was nothing difficult about it.

Antimatter technology itself is his main field, and its influence has been calculated in his mind for a long time, and this lecture itself is of a popular science nature, and will not involve specific technical indicators.

Seeing the experts who walked into the conference room one after another, including Academician Ma Mingwei, there are at least 5 academicians of the Chinese Academy of Engineering in the University of Engineering!

Liu Feng also has to admire the strength of other schools, at least compared to their University of Chemical Technology, it is really much better, after all, it is full of calculations, including him, there are only 3 academician-level bigwigs in Beijing University of Chemical Technology.

Finally, at the signal of Principal Lian, everyone had arrived.

So, Liu Feng, who was standing in front of the podium, simply tried the microphone, confirmed that the equipment was normal, and then started his speech.

The core content of the speech is to explain in plain language what antimatter technology and spacecraft based on antimatter power will be, and how these things will affect future dynamics and the comprehensive layout of ships.

It's just a lot of accumulation, and he didn't even use PPT, so he relied on a whiteboard and a pen, and Liu Feng spoke vividly.

However, no matter how popular science is, there must be certain knowledge points involved, so the first half is fine, but in the second half, in order to make his theory look more convincing and obvious, Liu Feng can't help but write a few lines of formulas on the whiteboard.

And then it was out of control.

It didn't take long for the entire whiteboard to be full, and even Liu Feng asked the staff to hand over two new whiteboards to continue to fill the ......

The 'students' sitting in the classroom, although all of them are senior-level experts and academicians, they can still listen to it fascinated in the first half, and they are completely confused in the second half.

"Regarding the reform of the future marine engineering university in the power and comprehensive layout of ships, the basic situation is like this," after the last letter was written, he threw the marker pen on the table, Liu Feng said with a smile, "That's all for my lecture, do you have any questions?"

All the students, including the principal, looked at him silently, as if they were still digesting what he was saying?

Half an hour later.

"If you don't have any questions, that's the end of today's lecture?"

"Wait,"

A gray-haired old professor stood up, not entangled in a series of formulas that Liu Feng wrote on the whiteboard in the second half,

"Professor Liu, I have to admit that you may be right, the future development of the Space Force is likely to form a development situation similar to that of the Navy's aircraft carrier battle group;

However, space fighters, similar to aircraft carrier-based aircraft, do not have a reliable development direction for the time being, so during this period of time, if we really meet an enemy who is 'worthy of a war', what kind of platform will we use as a tool for confrontation?

Do you think there will be a weapon platform like a naval battleship?

Or can 'battleships' completely replace the role of 'aircraft carriers'?"

Liu Feng: "......"

MMP。

I'm really not a military expert!

Liu Feng felt that his brain was a little painful.

This is another big debate about which is better or worse between battleships and aircraft carriers!

From the perspective of personal feelings, he actually prefers battleships, the form of giant ship cannon bombardment, is a real man!

However, from the lessons of historical development, aircraft carriers are obviously superior to battleships, and those devils in Toray feel this the most.

merely

One is the stars, the other is the sea,

Can this experience really be universal?

Perhaps, should, probably......

Right?!
