926 Ladder to Heaven, Ladder to Heaven! (2)

When the news reached the Forward Base, Ye Han was very surprised.

He is now a senior military official, and is fully responsible for many matters on Jupiter's moon. It can be said that he is in a high position and has great power. It is impossible for a project like this that must cooperate with the resistance organization to bypass him.

After Ye Han got the information, he read it carefully and roughly calculated it, and he immediately had a plan in his mind.

At that time, Ouyang Ping was beside Ye Han. He stared at the information twice and immediately widened his eyes: "Oh my god, I thought it was all the way to the space station. Why did you change the spacecraft in the middle?"

Ouyang Ping is now the chief quality inspector of the Forward Base. The most important job every day is to test the strength of carbon fiber-big fish arrange small fish, small fish arrange shrimp, Beidu gave the task to Ye Han, and Ye Han had to coordinate the overall situation, so he naturally couldn't do it himself. In addition, Luo Qi was stationed at the center of the earth, so this task naturally fell on Ouyang Ping's shoulders.

"It would be strange if it didn't change." Ye Han leaned back in his chair and changed to a more comfortable position. "Take a closer look. Don't you understand this?"

Ouyang Ping didn't look carefully at first. After hearing what Ye Han said, he took another look. Then he suddenly realized it and couldn't help laughing: "Railway tram? It's quite creative."

The most important supporting equipment of the rail elevator is the elevator cabin, but Beidu's design is not an elevator at all, but a tram. The design quality is still based on the strength of the fiber cable.

In other words, after the rail elevator is built, at most only one elevator can run on the cable that runs through the sky and the earth... No, it is a space train, one up and one down double track, but only two trains.

At a high-speed rail speed of 300 kilometers per hour, it takes a full 120 hours to get from the ground to the synchronous track, and during this time there can only be one space 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 a dock is added 120 kilometers away from the ground. The space train only needs to run 120 kilometers.

Although the change is small, it can increase the transportation efficiency of the elevator by a full 300 times under the premise that the strength of the cable remains unchanged!

In other words, the problem that can be solved by the improved plan only requires two aerospace trains, but the first version requires 600. As long as Beidu's IQ is normal, he will know how to choose.

Ouyang Ping continued to flip back and saw another set of improvement plans. He couldn't help but ask in confusion: "Hey, boss, why is there this?"

Ye Han pulled the corner of his mouth: "The superiors are worried about the unbalanced force of the double tracks, so they changed it again."

Ouyang Ping thought for a while, and nodded as if he understood: "It's only more than 100 kilometers, and the efficiency is not bad for one up and one down."

He didn't understand the specific imbalance, but he knew that the two tracks were connected to the same dock, one side was full and the other was empty, and the heights of the two cars were different. The force on the low-altitude dock must not be balanced. If the situation is serious, it may even affect the space station acting as a counterweight on the synchronous track!

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, while the improved version did not need such a place at all. However, the orbital elevator must have such a counterweight hammer located in the synchronous orbit, which is an important supporting facility that cannot be saved.

Ye Han pointed at Ouyang Ping and smiled: "Wrong, it's not up and down, but it's all over once it goes up."

"Ah?" Ouyang Ping didn't believe it at all, "Boss, don't lie to me, it only goes up but not down, are you assembling a train for fun?"

"I didn't say that you won't come down after you go up." Ye Han laughed.

Ouyang Ping quickly turned to the back, and after seeing the content behind, he rolled his eyes helplessly: "I said so!"

The space train is no different from a spacecraft except that it can't fly. After flying to the low-orbit dock, it doesn't need to return at all, but is towed away by a special spacecraft, and thrown back into the atmosphere at a suitable place, and landed on the sea surface with a parachute like a returning spacecraft.

The design plan calls this free recovery.

However, free recycling is only used when transporting a large amount of materials.

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 to go up, and it doesn't take much time anyway.

There are 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 carefully. He just scanned them and returned the documents 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 light-weight and high-strength materials."

"What is it for?" Ouyang Ping asked.

"The higher-ups are afraid that space debris will damage the cables, so they plan to add armor to the cables."

"No need to ask, the insect shell is definitely the most suitable." Ouyang Ping said.

Ye Han nodded: "Beidu thinks so too. You try to get a batch of insect shells back. The more the better."

The so-called insect shell is not the shell of a certain insect, but a general term for a series of alien building materials, that is, the main material of alien warships and the main material of alien buildings. It meets the requirements of light weight and high strength. Neither of them can think of anything more suitable than insect shells.

"I'll give it a try, but it may not work." Ouyang Ping had no confidence at all.

"It's okay. I'm not asking you to solve all the problems. I'm just going to get some samples for the superiors to choose. If they choose, we don't have to intervene. The superiors will talk to the aliens directly."

"I'm afraid that I won't get all the samples, especially the ones used on warships."

"No need for that kind." Ye Han said, "We have plenty of them. I guess the boss is interested in the shell of the battleship and asked us to find it just to see if there are any better ones."

"Okay, I'll ask Zeng Rui later." Ouyang Ping nodded and suddenly grinned, "The boss is not interested in those battleships, right? They won't even let us see them. Otherwise, you should talk to the boss and give up the idea. Who knows one day, the aliens will be able to mess with those battleships."

Beidu has always known that the resistance organization has a batch of alien battleships, and has thought about studying them in a cooperative way, but the resistance organization does not agree at all.

This matter is quite weird. Even planetary engines can be studied casually, and battleships that can't be driven at all are not allowed to be touched. I don't know what the aliens are thinking.

Ouyang Ping thinks that the resistance organization must have some ulterior motives, such as finding a way to crack the control system of the battleship or something, in short, they want to use those battleships.

"It would be great if it could fly." Ye Han said angrily, "Then we can just fly a few times and send the cable up to the sky!"
