How to apply all this power to the working medium is the key to the problem.
Even if he didn't exchange his savings over the past few years for East Asia Electric Power's stocks, this was not something Lu Zhou could afford on his own.
Although the internal structure cannot be seen, the text listed next to it explains its various experimental parameters in detail.
"Speaking."
After all, aerospace has always been linked to national defense. The reason why the country is willing to spend money on rockets is largely due to the development of rocket technology. It not only improves the aerospace strength itself, but also strengthens the country's strategic strike capabilities.
Too little drafting!
Lu Zhou: "Oh? Why?"
In fact, Director Li is also in a dilemma.
“…”
Lu Zhou smiled and said, "I can tell you with certainty that I did not write an extra letter. And we have proven through reliable experiments that its thrust can indeed reach KN level. Of course, I admit that using the maximum thrust The operating mode to overcome gravity will consume a lot of working fluid, but compared with traditional chemical rockets, it still saves at least 90% of the weight of fuel."
"Hall propulsion unit? What is this?"
Even, there is no need to waste any words to explain.
Hearing the discussion in the audience, the staff prepared to maintain order at the venue, but were stopped by Lu Zhou.
This is not out of rejection of new technology, but simply out of practicality.
"How about this."
Obviously this old gentleman is more prestigious.
It's normal to be disliked.
The people sitting in the meeting room, whether they were experts or business leaders, all subconsciously rubbed their eyes. However, no matter how many times I rub my eyes, there is no change in the data displayed on the PPT.
I can’t believe it, it’s just a judgment based on common sense.
"That's not necessary," Lu Zhou smiled and sighed, "No one who has ever said this to me has ever fulfilled their promise."
And the pupils were obviously filled with suspicion.
"It's not unbelievable, it's simply impossible! I have never heard of an electric propulsion system that can reach the KN level of thrust! Even the latest AEPS electric propulsion system designed by Rocketdyne for NASA is just an XR-5 The thrust of the Hall thruster has only doubled."
As if he expected someone to ask this question, Lu Zhou smiled and switched to the PPT.
However, Lu Zhou, who was also listening to these words, did not take it lightly.
"If you have any questions, please ask."
Although it was not the time to ask questions, and this technical demonstration did not leave time for the audience to ask questions, he knew that if he did not explain here, no one would listen to him.
"This is impossible! This is ridiculous!"
Electric propulsion system going to heaven
Although the electric propulsion system is good, for reasons of reason, he still prefers to choose the aerospace group's chemical rocket launch plan.
Before Lu Zhou could speak, the old man continued: "It is too early to adopt electric propulsion technology. We should focus our limited resources on chemical rockets to complete the first step of manned moon landing, and then try the so-called development limit. Higher new technology. If we adopt the electric propulsion technology you mentioned now, we will have to bear all the risks that may be brought about by all new technologies. Can you guarantee that your electric propulsion system is really that reliable? If it happens If an accident occurs, even if we can afford to wait, can our country’s aerospace industry afford to wait?”
“Unbelievable…”
Power alone is obviously not enough.
Academician Yuan was not angry but said with a smile.
The converted power of an RD-170 rocket is 192MW, and most of this power is used to propel the liquid fuel carried by the rocket itself. If the total power of this electric propulsion system can reach the level of 1,000MW, it may theoretically be able to send a 50-ton payload to low-Earth orbit.
A cylindrical object appeared in front of everyone.
However, after completing the assembly of the Hall propulsion unit and related tests, all doubts in his mind dissipated.
God
what to do
After standing on the stage and thinking for a moment, Lu Zhou suddenly felt something in his heart. He looked up at the smiling Academician Yuan and spoke.
Seeing that the topic of the meeting had turned to the thermos cup, Director Li, who was presiding over the meeting, suddenly coughed with a headache and tried to smooth things over.
Sure enough, after a moment of pause, the old gentleman suddenly changed the subject and spoke.
The development of science and technology itself is a process of subversion of past common sense.
This is tens of billions of dollars...
Hold the grass, am I right
"Let me say a few words."
"Perhaps one day in the future, the electric propulsion system you proposed will really change the face of the entire aerospace industry, but I don't think it is now."
Maybe in the future, but not necessarily now...
In fact, Lu Zhou doesn't really care whether others think highly of his research, but he cares about money...
The person who got up was Yuan Huanmin, chief engineer of the Aerospace Group and the person in charge of the Aerospace Group's latest high-thrust rocket project. After seeing this old gentleman, most of the people sitting here calmed down their discussions in a dignified manner.
The expert from the aerospace group who had previously presented the PPT on stage shook his head.
After waiting quietly for the discussion to subside, Lu Zhou spoke in a relaxed tone.
Although bragging on PPT is a basic operation, but you are bragging...
Whispers resounded in the Great Hall.
What's more, they can't put the controllable fusion device on the missile and throw it out.
Picture switching.
However, Lu Zhou was quite calm about this.
No matter how powerful the electric propulsion system is, due to the limit of the quality of the working fluid, the thrust will still be inferior to that of the chemical engine. Even if it has a greater advantage at longer ranges, ballistic missiles cannot use this advantage.
Seeing that the situation was developing out of control, Director Li, who was presiding over the meeting, was about to speak, but at this moment, an old man sitting in the front row of the auditorium stood up.
Lu Zhou looked towards the old man and saw that the old man was also looking at him.
A representative from a private aerospace company that had just received investment from Penguin had a look on his face that didn't know whether to laugh or cry.
Controlled fusion miniaturization technology is important, but is electric propulsion technology equally important
"If you can really do it, I will eat this thermos cup."
Facing Chief Engineer Yuan's question, Lu Zhou shrugged and said without any change in expression.
In fact, when the structural diagram of the Hall propulsion unit was recovered from Wreck-3, Lu Zhou was full of doubts about whether this thing could really push the space shuttle from the surface to low-Earth orbit. After all, according to the information that had been made public Look, even NASA's most powerful electric propulsion system can only lift an egg.
Why did this great expert in the field of chemical rockets also support this guy’s views
However…
"I have never heard of an electric propulsion system that can reach the KN level. I would like to ask Professor Lu, are you sure you didn't write an extra letter?"
The old man smiled and said: "The development of any technology is inseparable from a step-by-step process. The birth of new technologies cannot mature in a day or two. Just like quantum computers, they obviously already exist, but we still Spend more energy on improving traditional supercomputers, not because quantum computers are bad, but because they are not good enough... I say this, do you understand?"
"I don't see what's 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 into the same engine?"
This script is not quite right...
The old gentleman’s words were also recognized by the vast majority of people.
Lu Zhou believed that after seeing that astonishing scene, they would naturally understand the shock they felt at that time.
After all, for someone who has studied electrochemical rockets all his life, it is not only unbelievable, but also difficult to accept emotionally and rationally.
"That's what I'm going to say next."
Because compared to others in the audience, he could see the old man's eyes clearly.
Seeing the expression on Director Li's face, Lu Zhou roughly guessed that the Bureau of Science and Industry was probably reluctant to invest money in electric propulsion technology, but it was just because of his own dignity that it was inconvenient to express his position.
After the eerie silence ended, the voices of discussion spread like a tide.
The old man shook his head and went back.
The discussion in the auditorium gradually died down.
In the field of chemically powered rockets...
Looking at the old man who raised his hand, Lu Zhou nodded.
However, after seeing these parameters, the participants who had finally calmed down once again fell into a wave of surprise and heated discussion.
“I understand very well that Professor Lu, as an expert in the field of controllable fusion, has a special liking for the technical route of electric rockets. I admit that controllable fusion has changed our way of life, and I also admit that electric propulsion technology is a very important technology. A direction with potential.”
Soon, another expert from the aerospace group pushed up his glasses and stood up.
"I have a question."
"Everyone has a friendly discussion... Today is mainly about announcing the bid documents. The specific technical route to be adopted depends on your bidding materials. As for our Bureau of Science and Industry, we will also conduct research with other departments such as the Space Administration and refer to the quotations and quotations of each unit. Technical parameters, choose a suitable solution.”
"Since you are so confident and sure that I can't do it, let's make a bet."
After hearing this sentence, many people were confused.
"Small reactors of 500-1000MW... 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 increase the jet velocity? Increased to one thousandth of the speed of light?”
Standing up slowly from his seat, the old man stared at the PPT for a while, then looked at Lu Zhou and spoke carefully.
Soon, someone raised their hand.
Although Lu Zhou is nominally the general consultant of the lunar landing project, he does not hold the real power in his hands. Moreover, there are specialties in the field, and if a master of controllable fusion comes to the aerospace field, his voice may not be much higher than that of a newcomer, at least in the minds of most practitioners.
"As long as I can prove that this electric propulsion system can send a 50-ton payload into low-Earth orbit, it will be fine."
