Chapter 1004 The Truth Emerging From Practice

Jiang Chen almost laughed out loud after seeing the entrance of this cargo spacecraft clearly.

I dare these old fools to directly modify the rocket, install a quadruple-mounted main engine in the middle, cancel the design of the three-stage rocket, and design the fuel tank at the bottom of the middle section of the spacecraft, with the cargo warehouse above it. Although the overall layout has reached a level beyond the times, the power system is still a primitive chemical fuel engine.

The advantage of this rectangular aircraft lies in its straight longitudinal acceleration, which can effectively alleviate the load on the aircraft shell during the acceleration phase. But at the same time, problems also arise. It would be troublesome for this kind of spacecraft to turn in space. It's like a toothpick. If you hold the toothpick and poke it straight into the wall, it will be difficult to break. But if you pinch both ends and break it, it will break in the middle without much effort.

It is no problem to make a small turn through the speed difference of the four engines, but to turn more than 90 degrees, I am afraid that it will have to rely on the gravity of the planet to complete it. Unless they add a small engine in the middle, but then the entire hull will be too bloated.

Speaking of this engine, Jiang Chen still blushed a little. After all, he had tricked others. After the space elevator was built, the future of chemical fuel rockets like RM-320 would basically be over. With a high energy storage battery and a palm-sized cesium metal block, the cruise radius can be as large as that of a traditional chemical fuel rocket carrying two fuel tanks the size of a small house. The limitations of technology are here, and they cannot be solved by simply improving the technology.

Just like a bronze knife, no matter how hard you hone your forging skills, you can't compete with a knife made of steel.

"Although it is not impossible to use chemical fuel engines as engines, they can only be used for a while, and they will be eliminated in another twenty years at most. Medium-free propulsion rockets are the general direction of future aerospace development. One bite will make you fat. It's difficult, but we can start with electric propulsion first... Don't take notes, I just said it casually." Jiang Chen looked at the big-nosed man who took out his notebook from his pocket and started writing, and suddenly there was something on his face Unable to hang on anymore, he hurriedly said.

He really doesn't understand aerospace. The only role he plays in the Star Circle Commercial and Aerospace Department is to store the files from the apocalyptic side in the database of the modern side. Each department only deals with their own affairs. No one knows who researched these documents.

However, he still knew a little bit about the general direction, so he just said it casually. As for whether he can't help but scrutinize, Jiang Chen himself is not sure.

Yuri rubbed the back of his head in embarrassment, "I think what you said makes sense, but we have been studying the principle of fluid-free propulsion since the Soviet era, but we have not come up with any results until now. Electric propulsion We do have a prototype of the rocket, but the propulsion power is too low and cannot match the carrying capacity of this chemical rocket."

"If you have researched all this, it's time for us to come to your place to learn from you." Jiang Chen saw that the Russian had a good temper.

So I also started joking with him.

"Going for scriptures? What is learning from scriptures?"

However, although Yuri spoke Chinese fluently, he was obviously not very good at speaking it. He scratched his head and still didn't understand that Jiang Chen was joking with him, so he asked seriously.

"Well, it's nothing. You can think of it as studying."

Yuri made a look of realization, but then shook his head, took out a piece of information from his pocket and handed it to Jiang Chen's hand.

"There's no need to take lessons. I just want to ask, what do you think of this aircraft? Can it be parked at the port of Halo City? If not, please tell us if there are any deviations from the specifications."

Jiang Chen took this densely packed document written in English and looked at it for a long time without seeing anything interesting, and finally returned it to Yuri.

"I can't answer this right now. In fact, you don't need to give me this document. The technicians I brought here are dedicated to the task of identification. When the time comes, we will import the parameters of the aircraft into the computer, and we will Use the simulation program to check whether it can meet the safety standards and you will know after a try."

This time he came to the Russian Aerospace Group mainly to help them review whether the Archduke Oleg could dock at the Star Ring Trading Port. Don't underestimate this procedure. It's not just a random aircraft that can be transported between the Earth and the Moon systems. The speed of outer space is measured in kilometers per second, and the losses from accidents are also counted in hundreds of millions. . Even for the safety of Star Ring City, there is no room for carelessness in this matter.

But this has nothing to do with Jiang Chendao. He mainly comes here to show his face. After all, these are extraordinary times, and his real purpose of coming to Russia has to be concealed from others. Just like the leader's inspection, the technicians who came with him are the ones who really do the work. It doesn't matter whether he is the leader or not.

However, Yuri didn't think so. Jiang Chen's argument that "chemical rockets have no future" simply pierced his heart. Someone may ask, if Jiang Chen, an outsider, can see such a simple question, why can't Yuri, an aerospace technology expert who specializes in this kind of meal, still not understand it?

This involves a problem of a scientific research school.

One is propelled by working fluid and the other is propelled by non-working fluid. Which one do you want to say is wrong? Is there any right or wrong in scientific research? Scientific research is not a college entrance examination. Nothing is wrong, and there are no standard answers. There are two research directions, one focusing on the present and the other looking to the future. Persisting in the research and development of chemical fuel rockets with higher efficiency, the thrust value ratio of RM-300 compared to Falcon 9 rocket has doubled. If we continue on this path, who can say that it can’t be doubled again? Before the flintlock came out, muskets might not be able to defeat bows and arrows.

Yuri is actually playing a trick here. He copied down what Jiang Chen said not to take notes, but to use his halo to persuade those who support continuing along RM-320. Colleagues, go and convince those bosses who are more optimistic about the cost-effectiveness of working fluid propulsion rockets.

Although Jiang Chen claimed that he didn't know anything about aerospace technology and only understood the general direction, who would doubt that any of his words were wrong? Many people regard him as the founder of mankind's second "Age of Discovery", comparable to Columbus and the Mazelena people.

Not to mention the Russian Aerospace Corporation, which relied on the Soviet Union, even the director of NASA came, just to copy notes. This is not some academic authority, this is the truth from practice, what? have opinions? It’s easy to say, I’ll wait until you build a space elevator one day!

After copying several pages of notes, Yuri smiled so hard that his lips almost reached his ears. He enthusiastically sent Jiang Chen to the door of the car, watched 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 really couldn't associate the man in front of her with the word scientist. However, she was really unsure about how she could fool a technical director like Yuri into taking out his notebook.

"You...what you just said is true?"

"You're fooling around, bragging, you know? Anyway, idle time is idle." Jiang Chen smiled and said, "But don't say it, I may not understand much about this basic theory, but in terms of the general direction, There is no one in the world who can see things more accurately than me."

As for why, it goes without saying.

Natasha nodded blankly, not knowing which part of him she believed.

After being silent for a while, she suddenly spoke.

"Let me discuss something with you."

"What's the matter? Tell me." Jiang Chen looked at Natasha with some surprise. He thought that this girl wouldn't even talk to him today, but he didn't expect that his anger would disappear so quickly. Moreover, the tone of this discussion was really not something that someone with her carefree temperament could express.

After hesitating for a moment, Natasha spoke.

"The cocktail party in the evening...can you go by yourself?" (To be continued.) Activate a new website
