Metropolis: My IQ is 300

Chapter 131

The birthday is still going on, and the people who came have already filled the yard. Chen Fan never expected, unknowingly, that many, many people were already standing next to him.

Chen Fan's parents are very happy. These people are really good to Chen Fan from the heart. This is inevitable.

In the afternoon, everyone had dinner, and Li Fansheng felt ashamed of himself at the dinner table.

‘I’m really ashamed of my nickname for a knife, really. ’

Qiu Hua comforted and said: "Okay, no work, this is a good thing, the doctor has no work, this is a great good thing, so don't think about it so much."

"I know, but I don't want to hold this money. I feel that I am a bit embarrassed and ashamed of this money."

"You use your character as a guarantee, naturally it's okay."

"If there is anything that needs to be guaranteed, there are too many people who can do this."

"Who let you know Chen Fan?"

Li Fansheng had no way to refute this sentence. Chen Fan took the bone and gnawed happily.

The food is very satisfying. This birthday, Chen Fan is very happy.

Recalling the last birthday, Chen Fan was still eating dumplings, and his family stayed with him.

And now the birthday seems to be lively.

"Would you leave at night?"

Chen Fan nodded and said, "Yes, I will leave at night, and I will go back during the exam."

Qiu Hua nodded.

"The base is basically completed, and the team is already ready. The drawings you gave are already being produced. I have a question now, what exactly are you going to send to space?"

Chen Fan took out a box from his arms.

"this is?"

"A picture of my grandfather, and one of his favorite stones."

Qiu Hua was taken aback for a moment, looked at Chen Fan, and said, "So, you hope your grandpa can go to heaven?"

Ha ha ha ha.

Anna smiled, Qiu Hua felt that it seemed wrong to say that, and said, "That's not what you meant, why are you doing this?"

"Grandpa told me an interesting thing. When people die, they will turn into stars. Looking at those who care about them in the sky, I think my grandpa will look at me in the sky, but science can’t prove it. I sent the photo and the box, and I think it’s okay."

"I... wait, something is wrong, Chen Fan, you are lying."

Qiu Hua's wife handed Qiu Hua a bottle of wine, just because you talk too much?

Only then did Qiu Hua react.

Yes, I do manage a little too much.

Everyone has selfish motives. Chen Fan worked so hard to deliver something that he didn't want to be known.

"Guess me, how much did the rocket cost this time?"

"I won't ask, because it's not good for me to ask, I don't want to know this."

After finishing the meal in the afternoon, Chen Fan was sent away in the evening, came to the base, and started his own preparations.

And everyone went home one after another, preparing for their own affairs. The New Year is approaching, and the Spring Festival is actually the core.

Chen Fan was immersed once again, but in exchange for the cleanliness of Weibo, once again he will not be listed by various academics.

Because it's very simple, you are always hung up on the existences that I see very awesome, this way, we have a headache.

And Nobel is also proceeding in an orderly manner. This time, everyone is waiting for Chen Fan to come to accept the award.

The persons in charge gathered together and discussed with each other.

"In fact, I think any physicist can complete the production of rockets, and getting the quota is the key."

"Yes, there are a lot of uncertainties in the rocket's lift-off, and it is a big problem in itself to want to lift-off under tight protection."

"I think you should be worried about the impact if Chen Fan sends Xiaomei into space."

"That's people's freedom. If you can write this program, you are eager to send it to space. Don't you want to protect yourself?"

Hahaha, a group of people are sitting together and chatting with each other.

And here, the Nobel award ceremony is in the evening, and I don’t know if Chen Fan can catch up.

"You said, Chen Fan will choose a solid rocket or a liquid rocket. I feel a little bit, it may be a solid rocket."

"Nonsense, I think it may be a liquid rocket, the propellants stored in the tank, such as nitric acid and kerosene. Cryogenic propellants refer to propellants with low boiling points at room temperature, such as liquid oxygen and liquid hydrogen.

With the development of aerospace technology and the increasing requirements for environmental protection and human health, the main rocket engine is currently moving towards the use of non-toxic and non-polluting liquid hydrogen, liquid oxygen and liquid oxygen, kerosene propellant, etc. These are the mainstream. The development direction of the company, but unfortunately, the technology card holder. "

"Of course it's the owner, because the core ns equation can't be solved, and I heard that Chen Fan is dealing with the ns equation, but it seems that progress is not very good."

"That subject actually has research value, but it will take a long time."

Wilson took a cup of coffee, came to the table, and joined everyone in the discussion.

"It feels like Nobel delayed Chen Fan's rocket launch."

Hahaha, everyone at the table is smiling.

"Wilson, this year I thought that your student would become the best, but I didn't expect that Chen Fan would be the best. This is really shocking."

"Oh, there is no way, but I heard that Chen Fan's rocket is about to take off. He also sent a message to me a few days ago, saying that he is a trash and has not solved the ns equation. In the end, he can only use a solid rocket. "

The solid rocket motor is the simplest kind of chemical rocket motor. The solid propellant it carries is mainly composed of fuel and oxidant. It is usually made of a red pillar with a certain geometric shape and stored in a semi-closed container called a combustion chamber.

In order to ignite the grains, an ignition device with a safety mechanism is installed at the head of the combustion chamber. After energization and ignition, the grains in the combustion chamber are ignited and continue to burn to produce high-temperature, high-pressure gas

(Working fluid), at this time, the chemical energy of the solid propellant is converted into heat energy; the gas is discharged at a high speed through the Laval nozzle at the tail of the combustion chamber, thereby generating thrust to propel the rocket forward.

Heat energy is transformed into kinetic energy.

Compared with the liquid rocket engine, the solid rocket engine does not need a propellant delivery system, and the thrust chamber does not need to be forced to cool, so the structure is simple, and there are no valves, injectors, turbo pumps, and combustion engines.

Parts such as gas generators. Due to this feature, it is highly reliable and easy to operate. In addition, the solid engine can be stored for a long time. The disadvantages of solid rocket motors are: lower than expected,

The working time is short, it is not easy to adjust the thrust and to start multiple times.

Everyone has information about solid rockets in their minds, and naturally they all understand what effects solid rockets can bring.

"I think the fuel may be replaced, and nuclear power is the choice."

"Yes, nuclear power has always been the core, but it has no civilian use. It is a big failure. However, Chen Fan started the car himself. I think in the future, Chen Fan will sell this engine."

"There are some technologies that you can buy, and some technologies you can't buy."

Someone looked up at the sky.

"I should thank Chen Fan. My wife’s cancer was cured by Chen Fan, but Chen Fan refused to receive the Nobel Prize in Medicine. This year’s recipient is the most uncomfortable."

"Are you talking about me?"

A man joined in, and everyone looked at him and said one after another: "Richard, I didn't expect you to become the biggest joke this year."

"What can I do? I thought I could get awards by relying on the gene sequences discovered in biology. Chen Fan told us that he had solved them all and started to use them. You may not know, my The experimental team, after learning of this news, the whole person collapsed, and in an instant, the funds for the experiment were cut."

Everyone laughed.

"But there is no other way. Chen Fan refused to take this award. He felt that he was not qualified because of cancer, and he didn't solve it."

"But the artificially cultivated retina and cornea are also okay."

"Well, do you think Chen Fan can accept the award? How many waste researchers do you know, what you want is to get Chen Fan's technology to do some illegal things."

"It's not that I don't know, but in this wave, Chen Fan really did a good thing. Illegal organ trading will not happen."

Wilson was looking at the notebook in his hand, looking at the model of the rocket.

"This is from Chen Fan."

"Does Chen Fan not worry about us imitating plagiarism?"

"Do you think it can be imitated?"

Everyone looked at each other. The last explosion on the US side was still vivid. Everyone saw it and imitated it. No one wanted to imitate Chen Fan's stuff anymore.

"The solid rocket motor is composed of grains, combustion chambers, nozzles, and ignition devices. The solid propellant is often made into different shapes, called grains. When the propellant is the same, the thrust of the solid rocket motor is The combustion surface of the column is determined.

The nozzle of a solid rocket engine has the function of converting the heat energy released by the propellant into kinetic energy for propulsion. Because it does not use cooling measures like liquid engines, it generally uses alloys.

It is made of high-temperature resistant materials such as steel or high-temperature glass fiber reinforced plastics, and is protected by ablation and other technologies. A solid rocket motor can be designed as one nozzle or several. There are fixed nozzles and movable nozzles. The movable nozzle can rotate or swing around the longitudinal axis of the engine to control the thrust direction of the engine. But Wilson, why do I think Chen Fan’s design is not right. "

"Oh, how do you say?"

"The rocket needs weight, because if you use carbon nanotechnology, then the overall weight will be reduced, so it will be severely unstable during the lift-off process."

"But what if you put something in the rocket?"

I rely on.

"How many things do you have to install? Are you joking with me internationally? China's rockets have always been famous for being huge and heavy enough."

"The idea of ​​other people's production is like this. Besides, as long as the ratio is right, it can be stable. What do you care about this? This is not something that Chen Fan needs to worry about. We are all physicists. We know something, Chen Fan Can't you think of it?"

The rocket structure system is usually a rocket body structure, mostly a hard shell or semi-hard shell structure composed of metal plates and reinforcements. Most materials have higher specific strength and specific rigidity, and the plasticity range is relatively high.

The narrow aluminum alloy is partially made of stainless steel, titanium alloy and non-metallic materials.

Counting down from the head of the rocket, the body structure of a multi-stage liquid rocket mainly includes a payload fairing, an instrument compartment, a propellant tank, a compartment, a compartment, a tail compartment, and a tail fin. solid

The structure of the rocket body of the rocket is basically the same as that of the liquid rocket. The difference is that it is relatively simple, and most of it is an engine casing.

A physicist raised a question.

"I don't agree with this design concept. The traditional rocket pursues speed and achieves the purpose of breaking through the atmosphere."

"This design is completely wasting resources. In this way, how much energy needs to be lost."

Ha ha ha.

Wilson said: ‘Artificial black hole plus graphene battery storage, how long do you think this rocket can last in space? ’

"Is this... showing off wealth?"

Many physicists have such a vocabulary in their heads. Chen Fan has installed various techniques and research results he has learned in a year on rockets.

And these technologies, no matter which one, are taken out or used casually, are all invaluable.

You know, this year, Chen Fan alone sells his own technology, and has even surpassed many rich men.

"I suddenly felt that Chen Fan's arrival this time would not be the kind of very stable arrival. If he takes a plane, I feel unrealistic."

"Hahaha, is it possible that Chen Fan will still come in armor? Supersonic speed, Chen Fan can't hold it, that is too slow."

Time was lost every minute, and in the evening, a car appeared over Sweden. ,

Then the car slowly landed and stopped at the door of the Nobel Prize Hall.

A man dressed in armor came out of the car.

With a smile on his face.

Pressing the button on the chest, the armor on his body gradually folded, was put away, and turned into a box.

It was held by Chen Fan.

Everyone looked at each other, f*ck, Chen Fan really came in armor.
