Scholar’s Advanced Technological System

Electric propulsion system?

God?

Holding the grass, I am not mistaken?

The people sitting in the conference room, whether they are experts or the heads of enterprises, have subconsciously squinted their eyes. However, no matter how many times the eyes are seen, there is no change in the data displayed on the ppt.

The aerospace group expert who had previously appeared on stage to show ppt shook his head.

A representative of a private aerospace company that just got a penguin investment, this time is a look of dumbfounding.

Although bragging on the ppt is the basic operation, but you blow this...

Also don't draft drafts too!

After the strange silence is over, the voice of the discussion spreads like a tide.

"incredible……"

“It’s not incredible, it’s impossible! I’ve never heard of an electric propulsion system with a thrust of kn! Even the latest aeps electric propulsion system designed by Rockayne for NASA is just xr-5. The thrust of the Hall thruster has doubled."

"..."

Hearing the voice of the audience, the staff was prepared to maintain the order of the venue, but it was indeed stopped by Lu Zhou.

Quietly waiting for the argument to fall, Lu Zhou said with a relaxed tone.

"What problems can be raised?"

Although it is not a question at the moment, this technical display does not give the audience time to ask questions, but he knows that if he does not explain here, probably no one will listen to himself.

Soon, someone raised their hand.

"I have a question."

Looking at the old man who raised his hand, Lu Zhou nodded and said.

"please say."

Slowly stood up from the seat, the old man stared at ppt for a while, then looked at Lu Zhou, and cautiously said.

"I have never heard of an electric propulsion system with a thrust of kn. I want to ask Professor Lu, are you sure you have not written one more letter?"

Lu Zhou smiled and said: "I can tell you with certainty that I didn't write a letter more. And we have proved through reliable experiments that its thrust can indeed reach the kn level. Of course, I admit that the maximum thrust is used. The operating mode to overcome gravity will consume a lot of working fluid, but it still saves at least 90% of the weight of the fuel compared to conventional chemical rockets."

The old man shook his head and did it back.

Soon, another expert from the aerospace group pushed the glasses and stood up.

"500-1000mw small reactor... This is beyond my knowledge. I haven't heard any rumors about this technology before, so I won't comment here. But the question is, how do you plan to spray? Is the speed increased to one-thousandth of the speed of light?"

An rd-170 rocket has a conversion power of 192 mw, and most of this power is used to propel the liquid fuel carried by the rocket itself. If the total power of the electric propulsion system can reach the order of 1000mw, it is theoretically possible to send 50 tons of load to the low earth orbit.

however……

It is obviously not enough to have light power.

How to apply all of this power to the working fluid is the key to the problem.

As if it was expected that someone would ask, Lu Zhou smiled and switched to ppt.

"This is what I will say next."

Picture switching.

A cylindrical object is presented to everyone.

Although the internal structure is not visible, the text listed next to it is a detailed description of its experimental parameters.

However, after seeing these parameters, the participants who had just calmed down were once again caught in the sound of horror and heated discussion.

"Hall propulsion unit? What is this?"

“I don’t see anything special about the design of this Hall propulsion unit. Since it works, why not make it bigger, but integrate countless so-called propulsion units in the same engine?”

"This is impossible! It's ridiculous!"

Seeing that the situation is moving out of control, Director Li, who presided over the meeting, was preparing to speak, but at this moment, an old man sitting in the front seat of the auditorium stood up.

"I have two sentences."

The arguments in the auditorium gradually subsided.

The person who got up was the chief engineer of the aerospace group, Yuan Huanmin, and the head of the space group's latest large-thrust rocket project. After seeing the old gentleman, most of the people sitting here have calmed down the voice of discussion.

Lu Zhou looked at the old man and saw that the old man was watching him.

"I understand that Professor Lu is an expert in the field of controlled fusion. He has a special liking for the technical route of electric rockets. I admit that controllable fusion has changed our way of life. I also admit that electric propulsion technology is a very There is a potential direction."

There was a whisper in the auditorium.

After hearing this sentence, many people are confused.

This script is not quite right...

How did the big bull in the chemical rocket field follow the idea of ​​supporting this guy?

However, Lu Zhou, who is also listening to this sentence, has nothing to lose.

Because he can clearly see the eyes of the old man compared to other people in the audience.

And in the pupil, it is obviously suspected.

Sure enough, after a pause, the old gentleman suddenly turned and said.

"Perhaps one day in the future, your proposed electric propulsion system will really change the face of the entire space industry, but I don't think it is now."

Lu Zhou: "Oh? Why?"

The old gentleman smiled and said: "The development of any technology is inseparable from a gradual process. The birth of new technology is not mature in a day or two. It is like a quantum computer, obviously already exists, but we still Put more energy into improving the traditional supercomputer, not because the quantum computer is not good, but because it is not good enough... I can say, can you understand?"

Not waiting for the Luzhou opening, the old gentleman continued: "It is still too early to adopt electric propulsion technology. We should concentrate limited resources on the chemical rocket, first complete the first step of manned landing, and then try the so-called development ceiling. Higher new technology. If you use the electric propulsion technology you mentioned now, we have to bear all the risks that all new technologies may bring. Can you guarantee that your electric propulsion system is really reliable? An accident, even if we can afford it, can our country’s space industry be affordable?"

The old gentleman’s sentence has also been recognized by most people.

Although Lu Zhou was named as the general counsel of the moon landing project, but after all, he did not hold the real power in his hand. Moreover, the industry has specializations, and the interlacing is like a mountain. The controllable fusion of the big cows has come to the aerospace field. The right to speak is not necessarily much higher than that of a newcomer, at least in the minds of most practitioners.

And in the field of chemically powered rockets...

Obviously this old gentleman is more prestigious.

However, Lu Zhou is quite calm about this.

It is normal to not be optimistic.

After all, for those who have studied the electrochemical rocket for a lifetime, it is not only too ridiculous, but also difficult to accept.

In fact, when the structure map of the Hall propulsion unit was recovered from the Remnant No. 3, Lu Zhou was full of doubts about whether this thing could really push the space shuttle from the surface to the low earth orbit. After all, according to the published news. Look, even Nasa's strongest electric propulsion system can only lift an egg.

However, after completing the assembly of the Hall propulsion unit and related tests, all doubts in his mind disappeared.

I can't believe it, just an argument based on common sense.

The development of technology itself is a process of subversion of past common sense.

Lu Zhou believes that after seeing the amazing scene, they will naturally understand the shock that they produced at that time.

Even, there is no need to explain more.

Facing the question of the chief engineer of Yuan, Lu Zhou shrugged and said nothing.

"As long as I can prove that this electric propulsion system can send 50 tons of load to low Earth orbit."

Academician Yuan is not angry and laughs.

"If you can really do it, I will give it to this mug."

"That's not necessary," Lu Zhou smiled and sighed. "No one who has said this to me has fulfilled his promise."

Seeing that the topic of the meeting had already reached the thermos cup, Li, who presided over the meeting, suddenly coughed with a headache and hit the round.

"Everyone's friendly discussion... Today is mainly to publish tenders, which technical route to use, or to see your bidding materials. And our Science and Technology Bureau will also conduct research in other departments such as the Space Agency, refer to the quotations of various units. And technical parameters, choose a suitable solution."

In fact, Secretary Li is also very embarrassed.

Although the electric propulsion system is good, but for the sake of reason, he is more inclined to choose the aerospace group's chemical rocket launch program.

This is not due to the exclusion of new technologies, but only for practical considerations.

After all, aerospace has always been linked to national defense. The reason why the country is willing to spend money on the rocket is largely because of the development of rocket technology. It is not only the aerospace strength itself, but also the country's strategic strike capability.

The electric propulsion system is stronger and is affected by the quality limit of the working fluid. The thrust is still not comparable to the chemical engine. Even with a greater advantage over longer distance scales, ballistic missiles do not use this advantage.

What's more, they can't put the controllable fusion device on the missile and throw it out.

Controllable fusion miniaturization technology is important, but is electric propulsion technology equally important?

Maybe the future is, but it may not be...

Seeing the expression on Director Li’s face, Lu Zhou roughly guessed that the Science and Technology Bureau was mostly reluctant to invest in electric propulsion technology, but it was inconvenient to express his own face.

In fact, Lu Zhou is not very concerned about whether other people are optimistic about their own research, but what the money cares about...

This is a tens of billions of dollars...

Even if you don’t replace your savings for a few years with the stocks of East Asia Power, this is not something you can afford on your own.

What should I do?

Standing on the stage and thinking for a moment, Lu Zhou suddenly moved in the heart, looked up and looked at the smiling Yuan Yuan, and said.

"How about this."

"Since you are so confident and determined that I can't do it, we will make a bet."
