I Have a Mansion in the Post-apocalyptic World Chapter 1004: Truth from practice

Remember [lnmao.org] in one second, fast update, no pop-up window, free to read!

Seeing the doorway of this cargo ship clearly, Jiang Chen almost did not laugh out loud.

Dare to love these old Maozi directly changed the rocket, put the main engine in the middle into a quadruple, canceled the design of the three-stage rocket, and designed the fuel tank at the bottom of the midship of the spaceship, above which is the cargo warehouse. Although the overall layout has reached a level beyond the times, but the power system is still the original chemical fuel engine.

The advantage of this rectangular aircraft lies in the vertical acceleration from straight to straight, which can effectively relieve the load on the aircraft shell during the acceleration phase. But at the same time, the problem also came. This kind of spaceship would be troublesome to turn around in space. It's like a toothpick. It's hard to poke with the toothpick against the wall, but holding the two ends apart, it breaks in the middle without much effort.

It ’s no problem to make small steering through the speed difference of the four engines, but if you change the steering to more than 90 degrees, I am afraid that you have to use the gravity of the planet to complete it. Unless they add a small engine in the middle, but the whole hull is too bloated.

When it comes to this engine, Jiang Chen is still blushing. After all, he has pitted people on his side. After the space elevator is built, the future of the chemical fuel rocket RM-320 is basically over. A high-energy storage battery, plus a slap-sized cesium metal block, cruising radius can top the traditional chemical fuel rocket carrying two small house-sized fuel tanks. The limitations of technology are here, and it cannot be solved simply by improving the technology.

It ’s like a bronze knife. No matter how hard you forge your forging technology, you ca n’t compare it with a knife made of steel.

"Although it is not impossible to use a chemical fuel engine as an engine, it can only be used for a while. It will be eliminated in at least another 20 years. Propellant rockets without working medium are the general direction of future aerospace development. It ’s hard to eat a fat man, but we can start with the electric drive first ... you do n’t take notes, I just said that casually. ”Jiang Chen looked at the big nose Mao Zi and started writing directly from his pocket. Suddenly, I couldn't hold it, and said quickly.

He really does n’t understand the aerospace piece. The only role he plays in the Star Ring Trade and Space Department is to save the files from the end of the world to the database of the current world. Each department only cares about this piece. No one knows who researched these files.

However, he still knows a little bit about the general direction, so that's how he says it casually. As for being able to withstand scrutiny, Jiang Chen was not sure.

Yuri touched the back of the head embarrassedly, "I think you said something reasonable, but we have been studying the principle of working fluidless advancement since the Soviet era, but no results have been researched until now. We have prototypes of electric propulsion rockets, but the propulsion power is too low, and it is not comparable to the carrying capacity of this chemical rocket. "

"If all this has been researched for you, it is time for us to come to you and learn from it." Jiang Chen saw that this Russian has a good temper, so he joked with him.

"Learning? What is it?"

However, although Yuri's Chinese is very fluent, but the spoken language is obviously not learned at home, and he still hasn't heard Jiang Chen joking with him after touching his head. Instead, he asked seriously.

"Uh, nothing, you can understand it as learning."

Yuri made a surprise expression, but then shook her head and took a piece of information from her pocket and handed it to Jiang Chen.

"I do n’t need to learn from it. I want to ask, what do you think of this aircraft? Can you stop at the port of Star Ring City? If not, what are the specifications that exceed the standard? Please tell us. "

Jiang Chen took this dense document written in English and looked at it for a long time without seeing anything famous, and finally gave it back to Yuri.

"I ca n’t reply to you right now. You do n’t even need to give me this document. The technicians I brought are specifically for this task. At that time, import the parameters of the aircraft to the computer. In the test, we use a simulation program to check whether we can meet the safety standards and try it. "

This time he came to the Russian Aerospace Group, mainly to help them examine whether the Oleg Grand Duke could stop in the port of the Star Ring Trade. Don't underestimate this procedure, it is not just an aircraft that can go up and run between the moon and the ground. The speed of outer space is measured in kilometers per second, and the loss of the accident is counted in billions. . Even for the safety of the Star City, this matter can't be tolerated.

But this has nothing to do with Jiang Chendao. He mainly came here to show his face. After all, it is an extraordinary period. His real purpose of coming to Russia has to be concealed. Just like the leadership inspection, the real work is with the technicians who come behind him. Is his leadership the same?

However, Yuri does n’t think so, and Jiang Chen ’s statement that “chemical rockets have no future” is simply stuck in his heart. Someone may have to ask, such an obvious question can be seen by an outsider in Jiang Chen. Isn't Yuri, an aerospace technology expert who specializes in eating this bowl of rice, understand it?

This involves a research school.

One working fluid advancement, and one non-working fluid advancement. You have to say which one is wrong. Is there anything right or wrong about scientific research? Scientific research is not a college entrance examination. No one is wrong, and there is no standard answer. Two research directions, one focusing on the present and one focusing on the future. Adhere to the development of more efficient chemical fuel rockets. The RM-300 has doubled the value of the Falcon 9 rocket. Go down this path, and then turn up again. Who ca n’t say that? Before the flintlock came out, the musket might not be able to win the bow or arrow yet.

Here Yuri actually played a trick. He copied Jiang Chen ’s words not to make notes, but to use his aura to persuade those supports to continue along RM-320 Colleagues who go on to persuade those bosses who are more optimistic about the cost-effectiveness of the propulsion rocket.

Although Jiang Chen claimed that he did not understand any aerospace technology, but only understood the general direction, who would doubt which word he said was wrong? Many people regard him as the founder of the second "Earth of Navigation" of mankind, and they can be compared with those of Columbus and McZellen.

Not to mention the Russian aerospace group, which is based on the Soviet Union, the NASA director came, and it was also a copy of the notes. This is not an academic authority. This is the truth that comes out of practice. What? have opinions? It's hard to say, wait until you come to a space elevator!

After copying several pages of notes, Yuri ’s mouth was almost to the ear, and Jiang Chen was enthusiastically sent to the door of the car, watching him disappear at the end of the horizon, and then returned to the group building by himself. Even Natasha couldn't help but look at Jiang Chen twice. She couldn't really connect the man in front of her with the word scientist. However, she was really a bit unsure about being able to take out the notebook of Yuri ’s technical director.

"You ... was it all true?"

"Bullshit, bragging or not? Anyway, idle is also idle." Jiang Chen smiled and said, "But you really don't want to say, I don't know much about this basic theory, but in this general direction Problem, everyone in the world can see it more accurately than I do. "

As for why, it goes without saying.

Natasha nodded stunnedly, not knowing what he believed.

After a long silence, she suddenly said.

"Discuss something with you."

"What's the matter, let's talk." Jiang Chen looked at Natasha unexpectedly. He thought that this chick wouldn't talk to him today, but he didn't expect to disappear so quickly. And the tone of the negotiation is really not like her careless temperament.

After hesitating for a while, Natasha said.

"The evening reception ... Can you go by yourself?" (To be continued.)
