Chapter 690: We bet

Electric propulsion system to heaven?
God?
Hold the grass, am I right?
不管 Whether it was an expert or the person in charge of the company sitting at the conference table, he rubbed his eyes subconsciously. However, no matter how many times you rub your eyes, the data displayed on the PPT has not changed.
专家 The expert of the aerospace group who had previously come to show PPT shook his head.
Xuan Mou has just got a representative of a private aerospace company invested by Penguin, and now he has a crying expression on his face.
Although bragging on PPT is the basic operation, you blow it ...
I also do not draft too much!
As the weird silence ends, the voice of discussion spreads like a tide.
"Unbelievable ..."
"It's not incredible, it's impossible! I have never heard of an electric propulsion system that can reach KN level thrust! Even the latest AEPS electric propulsion system designed by Lockheed for NASA is nothing more than an XR-5 The thrust of the Hall thrusters has doubled. "
"..."
I heard the voice of the audience, and the staff was preparing to maintain the order at the venue, but it was stopped by Lu Zhou.
I waited quietly for the argument to drop, Lu Zhou said in a relaxed tone.
"What questions can be asked."
Although this is not the time to ask questions, and this technology demonstration does not leave the audience time to ask questions, he knows that if he does not explain here, probably no one will listen to himself.
I soon raised my hand.
"I have a question."
I looked at the old man who raised his hand, Lu Zhou nodded.
"please say."
Slowly got up from his seat, the old man stared at the PPT for a while, then looked at Lu Zhou, and said cautiously.
"I have never heard of an electric propulsion system with a thrust of up to KN. I would like to ask Professor Lu, are you sure you did not write an extra letter?"
Lu Zhou smiled and said, "I can tell you with certainty that I didn't write an extra letter. And we have proven through reliable experiments that its thrust can indeed reach KN level. Of course, I admit that the maximum thrust Mode of operation to overcome gravity consumes a large amount of working fluid, but compared to traditional chemical rockets, it still saves at least 90% of the weight of fuel. "
The old man shook his head and went back.
Soon, another expert from the aerospace group pushed his glasses and stood up.
"500-1000MW small reactor ... This is beyond my knowledge. I have not heard any rumors about this technology before, so I will not comment here. But the question is how do you plan to jet Speed ​​up to one thousandth of the speed of light? "
The conversion power of a RD-170 rocket is 192MW, and most of these powers are used to propel the liquid fuel carried by the rocket itself. If the total power of this electric propulsion system can reach the order of 1000MW, theoretically, it is indeed possible to send a 50-ton load to low-earth orbit.
However ...
It is obviously not enough to have light.
How to apply all these powers to the working medium is the key to the problem.
I seem to expect someone to ask this question, Lu Zhou smiled and switched to PPT.
"This is what I will say next."
Picture switch.
A cylindrical object appeared in front of everyone.
Although the internal structure can not be seen, the text listed next to it elaborates its experimental parameters in detail.
However, after seeing these parameters, the attendees who had not been able to calm down finally fell into a wave of consternation 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 so well, why not make it bigger, but integrate countless so-called propulsion units in the same engine?"
"It's impossible! It's ridiculous!"
Watching the situation go out of control, Director Li was preparing to speak, but at this moment, an old man sitting in the front seat of the auditorium stood up.
"Let me say a few words."
The argument in the grand hall gradually subsided.
The person standing up was Chief Engineer Huanmin Yuan of the Aerospace Group, and also the head of the latest large-thrust rocket project of the Aerospace Group. After seeing this old gentleman, most of the people sitting here calmed down the argument.
Lu Zhou looked at the old man and saw that old man watching him.
"I understand that Professor Lu is an expert in the field of controlled fusion. He has a soft spot for the technical route of electric rockets. I acknowledge that controlled fusion has changed our way of life and that electric propulsion technology is a very There is potential. "
Whispers rang out in the grand hall.
I heard this sentence, many people are confused.
This script is not right ...
Why is this big man in the chemical rocket field also supporting this guy's point of view?
However, Lu Zhou, who was also listening to this sentence, did not take it lightly.
Because he can clearly see the eyes of the old man compared to the others.
Suddenly, the pupils were mostly suspicious.
Sure enough, after a pause, the old gentleman suddenly turned and said.
或许 "Maybe someday 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 Lu: "Oh? Why?"
The old man smiled and said, "The development of any technology cannot be separated from a gradual process. The birth of a new technology does not mature in a day or two. It is like a quantum computer, which obviously already exists, but we still Put more energy into improving traditional supercomputers. This is not because the quantum computer is not good, but it is not good enough ... I say so, can you understand? "
After waiting for Lu Zhou to speak, the old man continued: "It is still too early to adopt electric propulsion technology. We should focus our limited resources on chemical rockets, complete the first step of manned landing on the moon, and then try the so-called development ceiling Higher new technology. If you use the electric propulsion technology you call now, we have to bear all the risks that the new technology may bring. Can you guarantee that your electric propulsion system is really so reliable? If it appears In an accident, even if we can afford it, can our country's aerospace cause be worth it? "
This sentence of Mr. Xun Lao has also been recognized by most people.
Although Lu Zhou was named the general consultant of the moon landing project, he did not hold his real power after all. In addition, the surgery industry has a specialization, such as intersecting mountains, and the controlled fusion of the Daniel comes to the aerospace field, the right to speak may not be much higher than a newcomer, at least in the minds of most practitioners.
But in the field of chemically powered rockets ...
I was obviously still more prestigious than the old gentleman.
However, Lu Zhou was quite calm about this.
It is normal to not be bullish.
After all, for people who have studied electrochemical rockets for a lifetime, they are not only unbelievable, but also unreasonable to accept.
In fact, when the structure diagram of Hall's propulsion unit was recovered from Wreck III, Lu Zhou was full of doubts about whether this thing could really push the space shuttle from the surface to near-Earth orbit. After all, according to the published information, Look, even NASA's strongest electric propulsion system can only lift an egg.
However, after completing the assembly and related tests of the Hall propulsion unit, all his doubts disappeared.
I can't believe it, just an assertion based on common sense.
科技 The development of science and technology is itself a process of subverting past common sense.
Lu Zhou believes that after seeing that amazing scene, they will naturally understand the shock they had at that time.
Even, don't bother to explain.
In the face of the question from Chief Engineer Yuan, Lu Zhou shrugged, and said with no change in expression.
只要 "As long as I can prove that this electric propulsion system can send a load of 50 tons to low earth orbit."
Academician Yuan Yuan smiled angrily.
"If you can do it, I will eat this mug."
那就 "Then don't have to," Lu Zhou smiled, sighing, "No one who has said this to me has fulfilled his promise."
Scrutinizing that the topic of the meeting had reached the insulation cup, Director Li, who presided over the meeting, suddenly coughed with a headache and hit the road.
"Everyone has a friendly discussion ... Today, we are mainly announcing the bids. Which technical route is used depends on your bidding materials. As for the Science and Industry Bureau, we will also conduct research on the space agency and other departments, and refer to the quotations of various units And technical parameters, choose a suitable solution. "
In fact, Director Li is also very embarrassed.
Although the electric propulsion system is good, for reasons, he still prefers the chemical rocket launch scheme of the Aerospace Group.
This is not for the exclusion of new technologies, but just for practical reasons.
After all, aerospace has always been linked to national defense. The reason why countries are willing to spend money on rockets is largely because of the development of rocket technology. It not only enhances the aerospace strength itself, but also strengthens the country's strategic strike capability EbookFREE.me ~ No matter how strong the electric propulsion system is, due to the influence of the working fluid quality limit, the thrust is still not as good as the chemical engine. Even with greater advantages over longer distance scales, ballistic missiles do not have this advantage.
What's more, they can't throw controlled fusion devices on missiles.
Controlled fusion miniaturization technology is important, but is electric propulsion technology equally important?
Maybe the future is, but not necessarily now ...
Seeing the expression on Director Li's face, Lu Zhou roughly guessed that most of the Bureau of Science and Industry was unwilling to invest money in electric propulsion technology, but it was inconvenient to express his face because of his own face.
In fact, Lu Zhou didn't care much about whether other people were optimistic about his research, but how much money did he care about ...
This is tens of billions of dollars ...
Even if Lu's savings have not been exchanged for the shares of East Asia Power, this is not something Lu Zhou can afford on his own.
What should I do?
I stood on the stage and thought for a moment, then Lu Zhou suddenly moved in her heart, looked up at the smiling academician Yuan and said.
"How about this."
既然 "Since you're so confident that you can't do it, let's make a bet."
