Going to work in the future, I drive back an aerospace carrier

In the afternoon, Wang Cheng made an appointment with Xiao Donglin for dinner.

"The two flaw detectors you got are a great achievement." Wang Cheng smiled: "The military said to come and toast you." "

"Not my credit." Xiao Donglin smiled: "But if you drink, I can do it for you." "

Wang Cheng laughed: "You also have merit, each performs his own duties." "

"My duty is to pimp, and drink the wine by the way."

There were words in Wang Cheng's words, Xiao Donglin did not accept his voice, and firmly established the character of the middleman.

Wang Cheng tried it, and saw that he refused to admit that it was Kunlun's person, and he no longer asked.

Eating, drinking, gossiping, from flaw detection to the plane itself.

"I heard that the worst we have right now is the engine?"

"Mainly engines." Wang Cheng nodded.

"What's wrong with the engine?" Xiao Donglin really didn't understand: "Isn't it all like that?" Draw a tiger according to a cat, as long as there is a lot of oil, if you don't believe it, you can't run fast. "

This is again illiteracy.

I don't understand the plane, you haven't seen the car, you build a tractor, fill a ton of oil at a time, can you run a sports car? Isn't that?

However, Wang Cheng has dealt with him several times and knows that this kid really doesn't read much, but he is not stupid, and he is a black belly, pretending to be crazy and selling stupid, one is not good, but he deceived him.

"I don't know the specifics." Wang Cheng shook his head: "But it should be mainly because of the materials." "

"We don't lack any materials, right?"

"Mostly composites." Wang Chengdao: "A single material is not good, it must be a composite material, several materials together, how to match, that is a big problem, in this regard, can only be tried little by little, can not surpass the car." "

"It seems to be." Xiao Donglin nodded: "My mother cooks like this, salty and light, always have to try, it is impossible to be accurate at one time." "

"How about abroad?" He asked.

"Much more advanced abroad." Wang Cheng sighed: "The thrust of our two engines is not even as good as their F35, they started early, there is no way." "

He said, looking at Xiao Donglin: "Xiao Xiao, you Kunlun, do you have the technology in this area?" "

"I don't know."

Xiao Donglin pushed it clean first.

Then he picked up his tail: "I'll ask." "

But he didn't pay attention this time, there was actually a pit in Wang Cheng's words.

Wang Cheng asked: You Kunlun.

Xiao Donglin didn't pay attention to this and didn't push it away.

But it doesn't really matter.

The next day, to the other side, Xiao Donglin checked, well, the technology here is either anti-gravity or space jump, and over there, it is completely far away.

He had to ask Ma Daha.

Ma Daha connected the net over there, and its wisdom brain touched the bottom over there, and understood more than Xiao Donglin.

"The engine over there, the active service is more advanced, the most typical is Mariken's F35, although it is a single engine, but it has a strong thrust, and the push ratio is 10 to 12."

"10 to 12?"

This time, Xiao Donglin didn't pretend to be stupid, he really didn't understand.

"It is the ratio between the output power of the engine and the weight of the body."

"Oh." This explanation, Xiao Donglin roughly understood.

But it didn't matter if he didn't understand, he asked a question: "What is the push ratio in our country?" "

"Between 8 and 9."

"It doesn't seem like a big difference, huh?"

8 and 12, isn't that a difference of 4?

"It's not." Ma Daha said: "The push ratio is one level worse, the efficacy is much worse, our best fighter, twin-engine, the push ratio is not as good as the F35 single-engine, two engines, add up to the power, but the efficiency ratio, but not so." "

Xiao Donglin didn't understand very well, and he didn't bother to understand, and said, "If you get the engine over here, what do you think it will be." "

"It depends, sir, what is your purpose?"

Ma Daha said: "If you just go there alone to install the machine, you can try to be as advanced as possible, and it is not a problem to push twenty, thirty, or even fifty." "

"Push to fifty." Xiao Donglin listened to the music: "That's not a rocket." "

"Almost." Ma Daha said: "Over there, another one or two hundred years of development, into the space and space of space aircraft, the plane will not be slower than the rocket." "

"Okay." Xiao Donglin was happy, but then came to his senses: "You mean, it will take one or two hundred years to develop." "

"Yes." Ma Daha said: "To achieve that kind of pushing ratio, the material requirements are very high, and it is impossible to do it now." "

"Can't do a full set of technical drawings in the past?"

"Can't do it." Ma Daha shook his head: "This is an extremely complex process that requires countless scientists to make breakthroughs in multiple fields, not a matter of a few drawings." "

He stopped and said, "Or that analogy, in your time, driving a plane to the Han Dynasty, they had to make it according to the drawings, how many fields did they need to break through?" "

"Quite so."

For this analogy, Xiao Donglin really understood, but he was helpless.
