"Forget it, I'll talk about it when I go back tonight." Ye Fan shook his head, thinking secretly in his heart, and then began to walk up the stairs.

Why not take the elevator? Because it hasn't been installed yet!

Behind Ye Fan, Shen Zhong also followed with a sycophant, either shouting for warmth or flattering.

It's just that Ye Fan is no longer surprised by these things, it's not that he likes to enjoy the feeling of being bragged about, but that he "doesn't stretch out his hand and don't hit the smiling person".

"Boss, General Manager Jiang." When they walked to the sixth floor, several Datang Technology security guards standing at the door also bowed to Ye Fan and Jiang Lang.

"Well, hard work." Ye Fan spoke, pushed open the three-meter-high and three-meter-wide mahogany door, and walked inside.

Only Ye Fan and Jiang Lang walked in, as well as Tang Xue and Ye Chengcheng, and Shen Chong was not a person from Datang Technology, so it was inconvenient to go in together, so he had to wait outside.

Because the exterior of the launch center building is built in a circular shape, the interior of the building is also a circular hall.

Inside the hall, there are more than a dozen large round tables, each with a dozen people writing and drawing.

The others were in a conference room on the side of the sixth floor, unaware of what they were discussing.

There are about 300 people on the entire sixth floor, and the remaining 100 people are constantly shuttling and measuring on the ground of the launch center outside the building, on the already poured foundation.

"Hello owner! Hello General Manager Jiang! Some people also noticed Ye Fan's arrival and raised their heads to say hello.

"Well, keep busy." Ye Fan nodded and motioned for them not to let go of the work at hand.

They are all planning the design drawings of the launch center, as well as the design drawings of the interior of the launch vehicle, and they have also marked various patterns and words such as ideas in some places.

The mining spaceship was designed by Origin, and they only needed to get the rocket right.

Ye Fan's idea is that the existing rocket thrust is completely insufficient, and even the rocket with the largest thrust cannot transport a complete mining spacecraft into the sky.

Therefore, the method adopted by Ye Fan is to launch a mining spacecraft into the sky three times, and then assemble it in a synchronous orbit.

The first mining spacecraft will fly to the moon, and there will be three of them, and if they are split, they will launch nine rockets.

If Ye Fan's dream is true, then there should be a large number of rare metals on the moon, which can be used to install on the body of the ion engine.

The speed of the ion engine could have been faster, but it was the metal material of the earth itself that limited its speed.

If you fly faster, the nozzle at the rear of the ion engine will be melted by the terrifying heat of the charged particle stream.

Even gold-titanium alloys are completely unusable, so high-grade metals must be refined to further increase the speed of the ion engine and thus upgrade it to the second generation.

However, there are no high-grade metal materials on the earth, and even if they do, they are stored in laboratories in various countries, and the amount is pitifully small. Night Night Chinese

Therefore, the first mining spacecraft flew to the moon to directly transport rare metals back to Earth, and then smelted them into high-grade metals.

That is, the legendary "gnawing old book".

The second batch of mining spacecraft, there will be four, and the rocket will need to be launched twelve times, or assembled in geosynchronous orbit of the Earth, and then the mining spacecraft will fly to Mars.

But Mars has a gravitational pull, and although it is weaker than that of Earth, it is not like the gravitational pull on the Moon is only one-sixth of that on Earth.

So when the time comes, only one of the four mining spacecraft will come back, and the other three spacecraft will essentially be parts of a large rocket launch platform.

They will be automatically assembled on Mars, and then a fully loaded mining ship will be launched out of Mars, and the mining ship will eventually fly back to Earth.

This mining spaceship returning from Mars will be the most important part of Ye Fan's plan.

Because it allows the ion engine to break through to the third generation, so that it can fly out of the atmosphere, although it cannot be said that it is such an exaggeration to fly to a high-synchronous orbit, but it already has the ability to fly to a low-synchronous orbit.

Therefore, the third batch of mining spacecraft will have five, divided into fifteen rocket launches, and equipped with the "solar sail" non-working fluid engine, in the next five months, these five mining spacecraft will fly to Mercury to collect resources.

When the third batch of mining spacecraft returns, the ion engine will officially have the ability to fly directly to a highly synchronous orbit from the ground, and then only need to start the electromagnetic propulsion engine, and then you can freely sail in space.

Therefore, these three batches of mining spacecraft are the key of the key, and the rocket is also very critical, but it cannot be regarded as the most critical step.

If they really can't design a reasonable layout, or can't come up with a high-thrust rocket engine, Ye Fan can also tell Guo Fengxiao to use the public rocket.

It's just that in this case, the matter of the mining ship will definitely be exposed, and at the current stage, it is not a good thing to expose this thing.

No one knows what Ye Fan thinks in his heart, even Jiang Lang, who has been with Ye Fan for the longest time, and Ye Tingcheng don't know Ye Fan's thoughts.

I walked all the way to the conference room at the end of the sixth floor, this conference room is very large, although it is said to be improvised, but the internal space is still very large.

After all, a conference room that can sit hundreds of people at the same table can be small, no matter how small it is.

Ye Fan gradually got closer and heard a nice female voice.

"No, Wang Tao, your plan can't be passed at all, your idea is to increase the volume of the rocket to get more thrust, but your approach,

It's as ridiculous as pouring two glasses of 50 degrees of water together to get 100 degrees, it's complete nonsense, as you increase the size of the rocket, the thrust required by the rocket will become greater.

Because it gets heavier, and because of the increase in volume, the friction with the air will also increase, so the total thrust will remain the same, and our existing materials will not be able to make a rocket as large as the one in your blueprint. ”

"Before the money, your design is not reasonable, the boss gave a hard condition, that is, let us maintain the maximum thrust at the same time,

It can also carry a carrier compartment at the front end of the rocket, although your design scheme increases the thrust, but the carrier compartment is also reduced, and can only carry the volume of three geosynchronous satellites in earth orbit. ”

"Zhao Liu, this design plan of yours is not reasonable..."
