When the news reached the forward base, Ye Han was very surprised.

He is also a high-ranking military official now, and he is also in charge of many matters on Europa, so it can be said that he is a high authority, and it is impossible for a project like this, which must cooperate with the Resistance, to bypass him.

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

At that time, Ouyang Ping was beside Ye Han, his eyes swept twice on the information, and his eyes immediately widened: "I'll go, I thought it was all the way to the space station, why did you change the spaceship in the middle?" ”

Ouyang Ping is now the chief quality inspector of the advance base, and 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 must coordinate the overall situation, naturally he can't do it himself, plus Luo Qi is stationed in the geocentric base, this task naturally falls on Ouyang Ping's shoulders.

"It's strange if you don't change it." Ye Han nested in the chair and changed to a more comfortable position, "You take a closer look, don't you understand this account?" ”

Ouyang Ping didn't look carefully, but when he heard Ye Han say this, he quickly took a few more looks, and then suddenly realized, and couldn't help laughing: "Rail tram? It's quite creative. ”

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

In other words, after the completion of the rail elevator, only one elevator can run on the cable that runs through the world...... No, it's an air train, one on and one on two tracks, but it's just two.

At the speed of a high-speed train of 300 kilometers per hour, it takes a full 120 hours to get from the ground to the synchronous track, and there can only be one sky train on the cable during this time!

This is a great waste of resources, and one that no one can tolerate!

It is not the same to add a pier at a distance of 120 kilometers from the ground, and the sky train only needs to run 120 kilometers.

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

In other words, the improvement plan only needs two sky trains to solve the problem, but the first version needs 600, as long as the IQ of the northern capital is still normal, you know how to choose.

Ouyang Ping continued to flip back, saw another set of improvement plans, and couldn't help but ask suspiciously: "Hey, boss, how can this still exist?" ”

Ye Han tugged at the corners of his mouth: "I was worried about the imbalance of the force on the double track, so I changed it again." ”

Ouyang Ping thought for a while, and nodded as if he didn't understand: "It's only more than a hundred kilometers, and the efficiency is not bad." ”

He didn't understand the specific imbalance, but he also knew that the two tracks were connected to the same pier, one side was full and the other was empty, and the height of the two cars was different, and the force on the low-altitude dock would definitely not be balanced, and if the situation was serious, it might even affect the space station acting as a counterweight in the synchronous orbit!

Thinking of this, Ouyang Ping wanted to laugh, the space station in the first version was an upright space station, a transfer center for the ground and outer space, and there was no need for such a place in the improved version, but the rail elevator must have such a counterweight hammer located in the synchronous orbit, which is an important supporting facility that must not be saved.

Ye Han pointed at Ouyang Ping and smiled: "Wrong, it's not a one-time up, but it's over." ”

"Huh?" Ouyang Ping didn't believe it at all, "Boss, don't fool me, you can't go up and down, save the train to play?" ”

"I didn't say I wouldn't come down if I went up." Ye Han laughed.

Ouyang Ping hurriedly flipped back, and after seeing the content behind, he rolled his eyes helplessly: "I said!" ”

Except that the space train cannot fly, it is no different from a spaceship, and after flying to the low-orbit dock, it does not need to return at all, but is towed away by a special spacecraft, found a suitable place and thrown back into the atmosphere, and landed on the surface of the sea with a parachute like a returnable spacecraft.

The design scheme calls this free recycling.

However, free recycling is only used when a large amount of material is being transported, and when it is not busy, it is better to let the train run on its own as much as possible...... It's much easier to go down than up, and it won't take much time anyway.

There are also some things such as cable handling technology, space station construction standards, low-orbit dock transfer plans, etc., Ouyang Ping didn't bother to look at them carefully, and probably returned the documents to Ye Han after scanning them.

Ye Han pointed to the document and said, "There is another task entrusted to you, contact the aliens to see if they have any materials with light weight and high strength." ”

"What's it for?" Ouyang Ping asked.

"I'm afraid that space junk will damage the cable, so I'm going to add armor to the cable."

"Then don't ask, it must be the most suitable worm shell." Ouyang Ping said.

Ye Han nodded: "Beidu also thinks so, you try to see if you can get a batch of insect shells back, the more the better." ”

The so-called insect shell is not a kind of insect shell, but a collective name for a series of alien building materials, that is, the main material of alien warships, but also the main material of alien buildings, which meets the requirements of light weight and high strength, and neither of them can think of anything more suitable than the insect shell above the above requirements.

"I'll give it a try, not necessarily." Ouyang Ping didn't have much confidence at all.

"It's okay, it's not for you to solve it all, it's just to get some samples for the top to pick, and if you pick it, you don't need to come out, and talk to the aliens directly."

"I'm afraid I won't be able to do it all, especially the one used on battleships."

"That doesn't work." Ye Han said, "What we have in our hands is, I guess it's the shell of a battleship, let us look for it, just to see if there is anything better." ”

"Okay, I'll ask Zeng Rui when I go back." Ouyang Ping nodded, and suddenly grinned, "Didn't you like those warships?" We won't even be allowed to see it over there, or you might as well talk to the boss, or don't bother with this idea, maybe one day, the aliens will be able to smash those warships into the air. ”

Beidu has always known that the resistance group has a batch of alien warships in its hands, and has thought about studying it in a cooperative way, but the resistance group does not agree at all.

It's weird to think about it, even planetary engines can be studied casually, and warships that can't be driven at all won't let people move, and I don't know what the aliens have in mind.

Ouyang Ping felt that the resistance group must have some ulterior motives, such as thinking of cracking the control system of the warships or something, in short, they wanted to use those warships.

"It's good to be able to fly." Ye Han said angrily, "When the time comes, you can fly a few times and send the cable to the sky!" ”
