When the news reached the advance base, Ye Han was very surprised.
He is now also a senior official in the military, and is fully responsible for many matters on Europa Zero. It can be said that he holds a high position of authority. It is impossible to bypass him for projects like this that require cooperation with the resistance organization.
After Ye Han got the information, he read it carefully, did some rough calculations, and immediately had a picture in his mind.
Ouyang Ping was beside Ye Han at that time. He glanced at the information twice and his eyes widened immediately: "I'll go, I thought it went all the way to the space station. Why did the spacecraft change in the middle?"
Ouyang Ping is now the chief quality inspector of the Qianjin Base. The most important job every day is to test the strength of carbon fiber - the big fish arranges for the small fish, and the small fish arranges for the shrimp. Beidou gave the task to Ye Han, and Ye Han must coordinate the overall situation.
Naturally, he couldn't do it himself, and since Luo Qi was stationed at the center of the earth base, this task naturally fell on Ouyang Ping's shoulders.
"It would be weird if you don't change it." Ye Han nestled in the chair and changed into a more comfortable position, "Look carefully, don't you still understand this point?"
Ouyang Ping didn't look carefully at first, but after hearing Ye Han's words, he quickly looked at it a few more times, then he suddenly realized it and couldn't help laughing: "Tram? It's quite creative."
The most important supporting equipment of an orbital elevator is the elevator cabin. However, the one designed by Beidu is not an elevator at all, but a tram. The quality of the design still depends on the strength of the fiber cables.
In other words, after the orbital elevator is built, only one elevator can run on the cable that connects the sky and the earth... No, it is a sky train, with one upper and lower double track, but only two trains.
At a high-speed train speed of 300 kilometers per hour, it takes a full 120 hours to get from the ground to the synchronous orbit, and during this time there can only be one sky train on the cable!
This is a huge waste of resources, and it is a waste that no one can tolerate!
It's different if you add a terminal 120 kilometers away from the ground. The sky train only needs to travel 120 kilometers.
Although the change is small, it can increase the transportation efficiency of the elevator by a full three hundred times while maintaining the same strength of the cable!
In other words, the improvement plan can solve the problem with only two sky trains, but the first version requires 600. As long as Beidu's IQ is normal, he will know what choice to make.
Ouyang Ping continued to scroll back and saw another set of improvement plans. He couldn't help but asked in confusion: "Hey, boss, why is this still there?"
Ye Han twitched his lips: "The superiors were worried that the forces on the two tracks would be unbalanced, so they changed it again."
Ouyang Ping thought for a while and nodded in understanding: "It's only over a hundred kilometers, so the efficiency is pretty good."
He didn't understand the specific reason for the imbalance, but he knew after thinking about it that two tracks were connected to the same pier. One side was full and the other was empty. The heights of the two cars were different. The forces on the low-altitude pier would definitely not be balanced.
, if the situation is serious, it may even affect the space station that acts as a counterweight in synchronous orbit!
Ouyang Ping wanted to laugh when he thought of this. The space station in the first version was an upright space station, a transfer center between the ground and outer space. However, in the improved version, there is no need for such a place at all. However, the orbital elevator must have such a facility located in a synchronous orbit.
The heavy hammer is an important supporting facility that cannot be omitted.
Ye Han pointed at Ouyang Ping and smiled: "Wrong, it's not about going up and down, but going up and it's over."
"Ah?" Ouyang Ping didn't believe it at all, "Boss, why don't you just stop fooling me, just go up and down, and save the train for fun?"
"I didn't say you won't come down after you go up." Ye Han chuckled.
Ouyang Ping quickly turned back and rolled his eyes helplessly after seeing the content behind: "I said so!"
Except that it cannot fly, the sky train is no different from a spaceship. After flying to the low-orbit dock, there is no need to return at all. Instead, it is towed away by a special spacecraft, found a suitable place and thrown back into the atmosphere, and then parachuted down like a return spacecraft.
to the sea.
This is called free recycling in the design plan.
However, free recovery is only used when transporting materials in large quantities. When it is not busy, it is better to let the train run down by itself as much as possible... It is much easier to go down than up, and it doesn't take much time anyway.
There were also some things such as cable processing technology, space station construction standards, and low-orbit terminal transfer plans. Ouyang Ping didn't bother to look at them in detail. He just scanned the documents and returned them to Ye Han.
Ye Han pointed to the document and said: "There is another task for you. Contact the aliens to see if they have any materials that are lightweight and strong."
"What's it for?" Ouyang Ping asked.
"The superiors are afraid that space debris will damage the cable, so they plan to add armor to the cable."
"No need to ask, insect shell is definitely the most suitable." Ouyang Ping said.
Ye Han nodded: "Beidu thinks so too. Try it and see if you can get a batch of insect shells back. The more, the better."
The so-called insect shell is not the shell of any kind of insect, but the collective name for a series of alien building materials. It is the main material of alien battleships and alien buildings. It meets the requirements of light weight and high strength. Both people want to
There is nothing more suitable for the above requirements than insect shells.
"I'll give it a try, it may not work." Ouyang Ping didn't have any confidence at all.
"It's okay. I don't want you to solve everything. I just need to get some samples for the superiors to choose. If you choose, we don't need to come forward. The superiors will directly talk to the aliens."
"I'm afraid it might be incomplete, especially the kind used on battleships."
"That's not necessary." Ye Han said, "We have plenty on hand. I guess the boss is interested in a battleship-like shell. Let us look for it just to see if there is anything better."
"Okay, I'll ask Zeng Rui later." Ouyang Ping nodded and suddenly grinned, "Isn't the boss interested in those battleships? They won't even let us see them, so why don't you talk to the boss?
, it’s better not to make this idea, maybe one day, aliens will be able to make those battleships fly away.”
Beidu has always known that the resistance organization has a batch of alien warships, and has thought about studying it through cooperation, but the resistance organization does not agree at all.
This thing is quite weird when you think about it. Even planetary engines can be researched at will, and warships that cannot be driven at all are left alive and untouched. I don't know what the aliens are planning.
Ouyang Ping felt that the resistance organization must have some ulterior motives, such as trying to crack the battleship's control system or something. In short, they just wanted to use those battleships.
"It's good to be able to fly." Ye Han said angrily, "When the time comes, I can fly a few times and send the cable to the sky!"
It's full of routines...if it's not anti-theft, add half of it, cry to death, pick it up again.
