Chen Nuo smiled: It's you, why did you come here?
What you said, Kyoto Aerospace is a university directly under the Ministry of Industry and Information Technology, and it guides the work from its own territory!
speak nicely!
The scholars who came to your report meeting yesterday proposed to visit here, let me see if there is anything missing.
Zhou Zhengfeng explained.
You came just in time, since it's your territory, get me some tickets, today's tickets are all booked, I can't get in!
Haha, take off your mask, and shout at the door: I am Chen Nuo, I guarantee that the management office will never dare to stop you!
Chen Nuo was speechless, if he could do this, he would have done it long ago.
The few leaders behind Zhou Zhengfeng listened to the chat between Zhou Zhengfeng and Chen Nuo, their foreheads were sweating, and they were a little dazed looking at Chen Nuo.
This boss came to his school, but he was blocked outside the museum. If it got out, he would probably be criticized again, even though they followed the rules.
Zhou Zhengfeng introduced several accompanying school leaders, who also came forward to say hello. He had met the principal several times before.
A leader was very excited, and trotted all the way to the management office when everyone was polite, and handed over a few visitor passes.
Professor Chen, do you want me to find a teacher to explain it to you?
Don't mobilize the crowd, my sister can do it, so you should do whatever you want!
So are you free today? I'll find you later?
After Zhou Zhengfeng finished speaking, he said in a low voice: Let me consult you about something.
If it's not too urgent, don't look for me today, I will give them two bags.
After Zhou Zhengfeng glanced at Luo Qingshi, he grinned, waved at several school leaders, and walked straight away.
After walking a long way, a school leader said: Minister Zhou, don't we need to prepare for Professor Chen's visit?Are you being rude?
Just pretend he hasn't been here before, don't stir up crowds.Zhou Zhengfeng waved his hand: Well, just arrange a few more security guards in the museum.
On the other side, the four of Chen Nuo brought their visiting passes and entered the museum.
Brother, the museum is divided into four parts, namely the exhibition area of chasing dreams in the sky, the exhibition area of silver eagle patrol, the exhibition area of sky and sky corridor, and the exhibition area of Shenzhou Wentian. Let's go to the exhibition area of chasing dreams in the sky first.
Chen Xiaorou acted as a guide.
An airplane formed by a holographic image is looming in the clouds. The various functional areas and components of the airplane are displayed in holographic images. Of course, there are physical comparisons next to it, which is very impactful.
The silver eagle display area is a variety of aircraft models of Kyoto Airlines. The holographic images are used to simulate the flight queues of various fighters in mid-air.
Here, Chen Nuo also saw the only two remaining Black Widow fighter jets in the world. The North Company produced a total of 706 planes, but they all died due to various reasons. If you want to see the real aircraft, you can only come here.
Along the stairs, you enter the exhibition area of the air and sky corridor. Models of different periods are projected in mid-air by virtual images, and cooperate with the key exhibits on both sides to echo each other, showing people milestones in the history of aviation development.
Finally, there is the Shenzhou Wentian District, which is an exhibition space intertwined with reality and dreams, reflecting dreams with reality, and various aerospace works.
During this process, Chen Xiaorou was familiar with the parameters and functions of each model.
In the end, Chen Nuo asked Luo Qingshi and the two to go shopping by themselves, while he stopped in the Shenzhou Wentian area. He did not forget to do his business.
Looking at the various spacecraft, Chen Nuo let out a low sigh in his heart.
System, sign in!
Chapter 584 Electric Propulsion System
System, sign in!
Ding!Sign in successfully, congratulations to the host for getting the electric propulsion system!
Hearing the sound of the system, Chen Nuo was a little surprised that he got the electric propulsion system.
The so-called electric propulsion system, also known as a rocket engine, is a device that can generate thrust without relying on chemical combustion, which can save a large number of complicated storage tanks and other equipment, and reduce the fuel carried by the spacecraft.
The electric propulsion system has the characteristics of high specific impulse, long life, small vibration and high precision.
传统化学燃料的比冲为2-4km/s，氢氧推进剂为4-5.5km/s，而电推进一般可达到10-100km/s。
This is the generalization of electric propulsion systems in the world at present. Although there are many advantages, the disadvantages are even greater, because its thrust is too small, so small that it can only push an egg.
It is only suitable for the attitude and orbit control of satellites, spaceships and interstellar probes, etc.
The spaceship with blue light on the tail in science fiction movies is an electric propulsion engine, including plasma engine, Hall thruster and so on.
The Hall thruster is a kind of electromagnetic thruster. Electric energy causes the working fluid to form plasma, which is then ejected from the acceleration tube by magnetic field confinement, thereby generating thrust.
The plasma propulsion uses electric energy to electrolyze the working medium to generate electrons and ions, which are accelerated and eliminated under the action of an electrostatic field to generate thrust.
Compared with the two electric thrusters, the Hall technology is simple but has a low specific impulse, which is suitable for orbit transfer and short-distance navigation, while the plasma specific impulse is high but the technology is complex, and is suitable for launch from the ground and long-distance navigation, such as interplanetary travel.
But without exception, both electric thrusters require a huge amount of electrical energy.
At present, the best in the world is M's X3. 100kw generates 5.4N of thrust. If this calculation is used, at least 2 kilowatts of electric energy are needed to lift a power armor of Xing Tian's medium 36 tons into the air.
This kind of high-power consumption, currently there is no battery on the earth that can meet this huge power demand.
Nuclear fusion is a choice, but the current nuclear fusion is uncontrollable, and the device is too big. Xia Guo has currently built the world's smallest nuclear fusion device Linglong No. [-]. The reactor is more than ten meters long, and the cooling device and other equipment add up to [-] yuan. It covers an area of more than [-] square meters and weighs hundreds of tons.
At present, no country on earth can get such a heavy thing into space.
Therefore, the current electric propulsion system on the earth is a tasteless one and cannot be used for the launch of aircraft.
Although the thrust of the current electric propulsion system is rubbish and can only generate a few oxen of thrust, its potential is huge, and it is incomparable to any chemical fuel for deep space. In theory, as long as the electricity can be large , the thrust is great.
The distance from Earth to Mars is 5500 million kilometers. It took 254 days for the Curiosity rover to float from space to Mars. If it is powered by electricity, it only takes 42 hours, which is the time it takes for the green train to travel from Shijiazhuang to Lhasa.
If you can solve the load of the acceleration process, traveling to Mars is not a dream.
After thinking about the generalization of the electric propulsion system in memory, Chen Nuo glanced at the information on the electric propulsion system he had obtained. Sure enough, as he thought, the electric propulsion system used a miniaturized controllable nuclear fusion power generation device.
Various materials are quite complete, including power processing unit, propellant storage and supply unit, thruster and other components.
what!
Looking at the information, several parameters suddenly made Chen Nuo lightly surprised, and then took out the phone to operate a few times, looked at the information displayed on the phone, and then thought about the system information, Chen Nuo smiled.
The power and thrust of the electric propulsion system given by the system is 100kw/16.8N, and the information shows that among the best countries in the world, Xiaguo is 20kw/1N, and M X3 is 100kw/5.4N , the system gives more than three times that of X3.
Don't underestimate the 3-fold gap, which means that the nuclear fusion device can be reduced by three times, or carry more nuclear reaction raw materials, and travel farther.
Chen Nuo sighed lightly. Controllable nuclear fusion is already difficult enough, but it needs to be miniaturized. Isn't this even more difficult?
He was also very speechless, why did the system give him this electric propulsion system?Does it make him star travel?
What the hell, the earth hasn't figured it out yet, isn't it courting death to go to an alien planet?
In just a short while, Luo Qingshi and Chen Xiaorou also came back from their shopping.
Let's go, I'm done reading here, I'll take you to eat some food in our restaurant and start our shopping trip!
Chen Nuo, who had just obtained the electric propulsion system, was slightly excited, but when he heard about the shopping, the excitement disappeared instantly.
Several people headed towards the school cafeteria, while several security guards in the museum let out a long sigh, this boss is really under a lot of pressure.
As soon as Chen Nuo and the others arrived at the restaurant, there was a leader waiting at the door.
Professor Chen, go to the private room on the third floor!
After the leader finished speaking, he quickly said: There are quite a lot of students in this restaurant. If you take off your mask in a while, the students will definitely recognize you. It's not good if there is an accident.
Fine!
The leader was right, and Chen Nuo didn't refuse, and went to a private room on the third floor.
It's really a simple meal, four dishes and one soup, all of which are ordinary dishes, but they are a little more delicate.
Is this really what our school restaurant chef did?Why is it different from what we usually eat?
After the meal, Chen Xiaorou had doubts and regrets on her face: I was thinking that you would call our principal after the meal to improve the restaurant.
Chen Nuo ignored Chen Xiaorou's little scheme.
Chen Nuo took Luo Qingshi and his sister to Dongfang Xintiandi, the place where he and Luo Qingshi went shopping for the first time.
So the scene of shopping last time could not be reproduced, but today with Chen Xiaorou as a living treasure, the scene made Chen Nuo even more desperate.
In a store, two people can go shopping for more than ten minutes, and try on a piece of clothing several times back and forth.
He also couldn't figure out where the fun was in it.
Two hours later, the two were still in high spirits, and Chen Nuo was already carrying seven or eight shopping bags.
Didn't the two of you just shop around before, and then go back to online shopping?
Anyway, you pay the bill, why bother with those things!
The two answered in unison.
Well, what you're talking about really doesn't cost a lot of money for these things, just for fun.
Another two hours later, when Chen Nuo had a few more shopping bags in his hand, Wei Bing, who was looking at Chen Nuo with more than a dozen shopping bags hanging from a distance, wanted to go up and help carry them, but he held back. Well, maybe Professor Chen is having fun while suffering?
If Chen Nuo knew Wei Bing's thoughts, Chen Nuo would probably say to Wei Bing: Thank you for your understanding!
Brother, sister-in-law, you go to the movies, I want to go shopping for a while, call me after you finish!
When preparing to watch a movie after dinner, Chen Xiaorou suddenly said this, and then slipped away.
When he left, he gave Chen Nuo an encouraging look.
Chapter 585 The Mysterious Gift
Holding Luo Qingshi, sniffing the scent of hair, watching a movie.
At this moment, Chen Nuo felt unusually at ease.
But no matter how peaceful he was, time would not stop for a second. The movie was over, and when the crowd left and found Chen Xiaorou, the girl was having a great time playing in the game hall.
After eating supper and returning to the courtyard, there was nothing to say all night.
The next morning, just after breakfast, Zhou Zhengfeng came to the door.
What happened, you came to the door so early.
Chen Nuo called Zhou Zhengfeng to sit down, and he was making tea.
three things!
Zhou Zhengfeng put down his cup.
The first thing is to be entrusted by someone to give you a gift.
What about gifts?
In the car, I'll send it in for you later.
Zhou Zhengfeng smiled: I'm afraid that if you take it in now, you don't have the heart to listen to me about the following things.
Then you might as well say it last.
Zhou Zhengfeng ignored Chen Nuo's complaints and continued: The second thing is that we are going to announce the BECCS (biomass energy combined with carbon capture and storage) technology.
Hearing this, Chen Nuo sat up straight: Are you ready?Are you not afraid that some countries such as M will jointly exert pressure, or local wars will break out?
You introduced this technology in September last year. We prepared it for nearly half a year. At the beginning, the recovery rate was only more than 9%. Some time ago, the machine tool technology breakthrough, and now it has reached more than 20.00%, and it can be gradually implemented.
The most important thing is that our development was too rapid last year, and those countries in the West could no longer bear it, and suppressed it openly and secretly;
At the Paris Agreement meeting some time ago, those countries made an argument that our carbon emissions are the world’s number one, and adjusted the proportion of our carbon emission indicators. According to the new proportion, we will spend nearly 1000 billion more dollars a year to purchase carbon index.
Zhou Zhengfeng's tone was a little angry and helpless.
If you don't join this organization, you will be besieged by the country headed by M. If you join, you will be limited by the carbon emission quota.
1000 billion knives, equivalent to RMB 6500 billion, this cost invested in any field can promote the rapid development of a certain field.
In fact, we found some experts to discuss this matter, but there has been controversy.Some people think that we can lie dormant for a while, wait until we have an overwhelming advantage, and then make a move.
Another group of people think that when it’s time to make a move, let’s make a move, not to mention that we have the Annihilation 20A, the Annihilation 20D, and the power armor made by Sun Gold. This is a waste of money.
There are also some people who are very stupid, thinking that the cost of BECCS transformation technology is too high, and the current development of nuclear fusion is very fast. If it will be changed to nuclear fusion in the future, carbon emissions will naturally decrease, and carbon storage is also dangerous and unsafe. Certainty.
Which brick houses are these?
Chen Nuo was also speechless, nuclear fusion is the clean energy of the future, that's right, but the first generation of nuclear fusion is not stable yet, still thinking about the future?
