Chapter 948 (2/2)

After watching the video for more than ten times, academician Liu sighed and crossed the video.

Seeing this, the middle-aged man standing behind him couldn't wait to ask.

”Well, academician Liu, do you see anything?”

Liu Zhusheng took a look at him, picked up the tea cup next to him, moistened his voice, and spoke slowly.

”If I'm right, their engines are powered by electric propulsion.”

The middle-aged man's face moved slightly, and he was about to say something, but academician Liu spoke slowly in front of him.”I know what you're trying to say, but it's impossible. Electric Rockets have more than one order of magnitude less thrust than chemical rockets.”

”But now I want to tell you that the specific impulse of electromagnetic propulsion system is much higher than that of chemical fuel propulsion system. According to the principle of electromagnetic addition, the exhaust degree of 12 orders of magnitude higher than that of chemical fuel can be obtained theoretically. I don't know what the future spacecraft will look like, but I'm sure it will not be possible for a future spacecraft to tie bundles of fuel tanks and waste a lot of precious fuel on the fuel itself. ”

”What you want to say is impossible, but we can't do it with our technology.”

Academician Liu's words made the middle-aged men speechless.

As the person in charge of China Aerospace Science and technology group, only this old man who designed Shenzhou series dare to talk to himself like this, and he is convinced. Although his administrative rank is much higher than that of him, in terms of the importance to this country, ten academicians can not compare with him.

At this time, the old man, who had been standing there without saying a word, spoke slowly.

”What about the laser knife that can cut through minerals”

”that's not a laser knife,” academician Liu shook his head. ”Although it's not my field, I know something about it. That thing, it's probably ion jet technology. Even if a piece of depleted uranium steel is placed there, a hole will have to be punched out

The old man's face changed slightly, and the shock on the middle-aged man's face was more obvious.

This means that even if the tank is placed in front of the ion jet knife, it has to be the same as the paper paste.

The old man asked in a deep voice, as he shrank in shock.

”Taking this torpedo P1 as an example, how far is the gap between us and them in electric propulsion and ion jet technology?” Liu Zhusheng shook his head.

”Our starting point in the space field is too low, and there is still a big gap compared with the United States and Russia. Directly compared with the star ring trade, to be honest, this is no match at all. ”

There is no such thing as

middle aged men can't help laughing bitterly.

Although Liu Nong's spaceflight group still has a dream, he can't get rid of it.

Just then the dignified old man spoke again.

”Strengthen cooperation with satellite ring trade, especially in the field of space. Since the vast prospect of outer space resources has been proved, we must not be left behind in this respect. ” When he said this, the old man was looking at the middle-aged man.

The middle-aged man will understand, immediately nod the way.

”Understand” to be continued. 8
