Seeing the doorway of this cargo ship, Jiang Chen almost didn't laugh out loud.
These old Maozis changed the rocket directly, and the main engine in the middle came in a quadruple installation. The design of the third-stage rocket was cancelled. The fuel tank was designed at the bottom of the middle section of the spacecraft. Although the overall layout has been beyond the standards of the times, the power system is still the original chemical fuel engine.
The advantage of this rectangular aircraft is the straightforward longitudinal acceleration, which can effectively alleviate the load on the aircraft's outer casing during the acceleration phase. But at the same time the problem has come, and the spacecraft wants to turn a corner in space and it is troublesome. It's like a toothpick, holding a toothpick to the wall and going straight to the ground, it's hard to poke, but pinching the two ends, it doesn't take much effort to break.
It is no problem to make a small shift by the speed difference of the four engines, but changing the steering of more than 90 degrees, I am afraid I have to use the gravity of the planet to complete. Unless they add a small engine in the middle, the whole hull is too bloated.
When it comes to this engine, Jiang Chen still has some blushing. After all, he is stuck in this place. After the space elevator is built, the future of the RM-320 chemical fuel rocket will basically end. A high-energy storage battery, plus a palm-sized slab of metal, the traditional chemical fuel rocket with a cruising radius can carry two small house-sized fuel tanks. The limitations of technology are here, and can be solved without simply improving the technology.
It's like a bronze knife. No matter how you temper the forging technique, you can't compare it with the tool that steel hits.
"It is not impossible to use an engine with a chemical fuel engine, but it can only be used. At most, it will be eliminated after another 20 years. The rocket without the working medium is the general direction of future space development, and eat a fat man. It’s very difficult, but we can start with the electric propulsion... You don’t take notes, I just said it casually.” Jiang Chen looked at the big nose hair and started to write the notebook directly from his pocket. Can't hang, and said quickly.
He really doesn't understand the spacecraft. His only role in the Star Trade and Space Department is to keep the documents from the end of the world to the database on the side of the world, and the departments only manage the affairs of each department. No one knows who made these documents.
However, he still understands the general direction, so it is so casual. As for the ban, he couldn’t help but scrutinize. Jiang Chen himself was not sure.
Yuri was embarrassed to touch the back of his head. "I think what you said is quite reasonable. However, we have not studied the principle of promoting the quality of labor. We have been studying since the Soviet era, but we have not studied the results until now. Rockets, we have a prototype, but the propulsion power is too low, and can not match the carrying capacity of this chemical rocket."
"If this is for you to study, it is time for us to come to you to learn." Jiang Chen saw this Russian temper is very good, so he also joked with him.
“What is the classics?”
However, Yuri’s Chinese is very fluent, but the spoken language obviously didn’t learn from home. He still didn’t understand Jiang Chen’s joke with him, but he asked him seriously.
"Oh, nothing, you can understand it as learning."
Yuri made a stunned expression, but even shook his head and took a piece of information from his pocket and handed it to Jiang Chen’s hand.
"I don't need to take it, I just want to ask, what do you think of this aircraft? Can you stop at the port of the Star City? If not, what are the specifications, please be sure to tell us."
Jiang Chen took this densely written document written in English and saw that he didn't see anything famous for a long time. He finally gave it to Yuri.
"I can't give you a reply now. I don't have to give it to me in this document. The technicians I brought are specifically for this task. I will import the parameters of this aircraft into the computer, we will Under the test of the simulation program, if you can meet the safety standards, you will know."
This time he came to the Russian Aerospace Group to help them check whether the Oleg Grand Gong can stop at the port of the Star Trade. Don't underestimate this procedure. You can't just get a plane up and you can run it between the moon system. The speed of outer space is measured in kilometers per second. The loss of accidents is also counted in billions. . Even for the safety of the city around the stars, this thing can not be sloppy.
However, this has nothing to do with Jiang Chen. He mainly came here to reveal his face. After all, it is a very special period. His real purpose of coming to Russia has to be hidden. Just like the leadership inspection, the real work is the technicians who come with him, and his leadership is actually the same.
However, Yuri does not think so, Jiang Chen’s argument that "the chemical rocket has no future" is simply poking into his heart. Someone may have to ask, such a shallow problem, Jiang Chen, an outsider, can see it. Isn't Yuli, a space technology expert who specializes in eating this bowl of rice, still can't understand?
This involves a problem with a research school.
A working medium advances, and a non-working quality advances. You have to say which one is wrong, is there anything wrong with scientific research? The 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 on the future. Adhering to the more efficient development of chemical fuel rockets, the rm-300 has turned upside down than the Falcon 9 rocket. Going down this road, who can't turn it up? Before the rifle came out, the musket could not even win the bow.
Here Yuri actually played a blind eye. He copied the sentence that Jiang Chen said was not for taking notes, but to use his aura to convince those who support to continue along the rm-320. Peer, to convince those bosses who are more optimistic about the quality of the work to promote the rocket cost.
Although Jiang Chen claimed that he did not understand aerospace technology, he only understood a general direction, but who would doubt which word he said was wrong? Many people have regarded him as the founder of the second "Great Navigation Age" of human beings, and they have to be compared with those of Columbus and Mazelen.
Not to mention the Russian Aerospace Group, which is the old Soviet Union. It is the director of NASA. It is the same as copying notes. This is not an academic authority. This is the truth that comes out of practice. What? have opinions? Well, wait for you to slap a space elevator and come out again!
After copying several pages of notes, Yuri’s mouth was slamming into the ear, and Jiang Chen was sent to the door of the car with enthusiasm, watching him disappear at the end of the horizon, and then he returned to the group building. Even Natasha couldn't help but look at Jiang Chen's eyes. She couldn't really associate the word man and scientist. However, she was able to give Yuri's technical director a flickering notebook, and she was really a bit unacceptable.
"You...just said what you said?"
"When you are fooling, do you know how to brag? Anyway, idle is also idle." Jiang Chen smiled and said, "But you really don't say that I can understand this basic theory, but the general problem, Everyone in the world can be more accurate than I can see."
As for why, then there is no need to say.
Natasha nodded and did not know what he believed.
Silence for a while, she suddenly began.
"Consult with you."
"What's the matter, let's talk." Jiang Chen looked at Natasha with some surprise. He thought that this chick would not talk to him today. I didn't expect it to be so quick. And this kind of tone is not like her savvy temper.
After hesitating for a moment, Natasha began.
"The evening reception... can you go by yourself?" (To be continued.)
