Homo sapiens

Egypt.

In early June, the two underground drainage tunnels of the Nile River in the Kom Ombo Junction Project were officially completed.

Then the engineering team cut off the surface channel of the Nile River, allowing the river water to pass through the underground drainage tunnel. The cut Nile River has a length of 3 kilometers.

A canaling ship dug the land between the Nile channel and the southern canal, and pushed across the desert to the west.

After more than a month of digging.

Finally, the southern canal was excavated to the Kharja oasis area, and then the canal cutter turned around and dug a parallel double track.

As the canal reached the Kharija Oasis, the Egyptian Aerospace City, which was previously located near the Jaja Manor in the Kharija Oasis, also ushered in the first wave of large-scale supplies.

Dr. Mikoyan and others, who had been eating sand here for more than half a year, finally breathed a sigh of relief.

After all, seeing the rapid development of other aerospace cities, they are still doing theoretical research here, which is really aggrieved.

on the temporary pier.

The group exchanged pleasantries for more than ten minutes, and then got straight to the point.

Dr. Mikoyan said confidently: "Don't worry, that plan has been simulated many times using supercomputers, and basically there will be no major problems."

Through holographic projection, everyone can see the model of the space shuttle.

In fact, it is similar to Lao Maozi's Blizzard space shuttle.

For example, in order to maintain the ultra-low temperature maintenance system of the space shuttle and adjust the feathers of the wings, a lot of electric energy is needed, so two small thorium-based molten salt nuclear reactors were simply installed.

This is why he hastily sought engineers and researchers from other systems to help.

Only this kind of super space shuttle can satisfy the space strategy of Homo sapiens.

The space shuttle designed by Mikoyan and others will carry 5000 tons of metal hydrogen as fuel, which is enough to push a space shuttle full of 3.2 tons into low-Earth orbit.

After discussing for more than three hours, I barely came up with a preliminary plan.

The thought of it being a space shuttle is just insane.

In a small office, he met Sen Shangzhe who made a special trip from the New Luzon Shipyard, and five other related engineers and researchers.

The engineer said this mainly because the space shuttle is too big, with a launch mass of 3.2 tons when fully loaded, which is almost 8 times that of the largest launch vehicle, the Saturn V.

Moreover, because Homo sapiens has a good foundation in the technology of explosive shock wave engines, the thermal efficiency of fuel can be further improved by using explosive shock waves.

The space shuttle of this design has a payload of about 1.2 tons.

But Wu Zhi had a troubled expression on his face.

"Doctor, Dr. Sen from the shipyard has arrived." The assistant shouted from a distance.

The mass of dozens of international space stations can be transported to low-Earth orbit at one time. Unless Homo sapiens' space elevator project and mass catapult project can be successful, otherwise no launch vehicle at this stage can match the payload of this project.

"Doctor, are you sure you want to use that plan?"

The reason for this design is mainly that the weight of the puller is too large, there is no way to erect it vertically, and it can only take a slope runway.

After all, it is necessary to complete the Guigong Project before 2030. With the current small rocket alone, the transportation volume is simply a drop in the bucket.

They calculated the explosive power of metal hydrogen, and then substituted it into the current metal material. After simulation calculations, they adjusted the engine's explosion chamber and nozzle parameters little by little.

Dr. Mikoyan reminded: "Don't forget the thrust and specific impulse of metal hydrogen."

According to the results of simulation calculations, the explosive shock wave engine they designed can further increase the thrust when using metal hydrogen as fuel.

Sen Shangzhe and others communicated in this base for more than a week.

Now that he has already assured the space department, Dr. Mikoyan will naturally go all out to get the experimental machine out as soon as possible, and then ask the space department to send money as soon as possible.

Dr. Mikoyan no longer cares about the tens of tons of payload of ordinary launch vehicles. He thinks that if he wants to play, he must play with a big one.

According to Dr. Mikoyan's design plan, the space shuttle does not need to stay in low-Earth orbit, or go to synchronous orbit, the moon and Mars, but as a carrying platform.

After flying out of the Karman line, you can directly launch the spacecraft it carries, and then the space shuttle turns around and returns to the atmosphere, returning to Space City.

Mikoyan and his assistant came to the underground area of ​​the base.

The other is the location of the spacecraft. After some simulation research, it was decided to place the spacecraft above the space shuttle.

Because this project was carried out in Egypt, it was named the "La" space shuttle project, or "La project" for short.

"It's really a simple and crude plan."

Dr. Mikoyan and base director Wu Zhi stood in the communication tower of the base, watching the three 5-ton container ships docked at the pier, unloading a large amount of supplies, and about 5000 new humans came here to support them .

Dr. Mikoyan patted Wu Zhi on the shoulder: "I'll trouble you about the pier. I'll go over and discuss the space shuttle plan with Dr. Sen first."

The quality of this thing is about the same as a Luzon-class amphibious assault ship.

But Sen Shangzhe thought about it seriously, because this thing fits his aesthetics.

In order to balance the explosive power of metal hydrogen and the problem of preservation, they enlarged the size of the space shuttle to the extreme.

Mikoyan was not angry, but said with a smile: "This is also the most effective solution. The maturity of metal hydrogen passivation technology is still unknown, and I don't want to waste time."

The Ministry of Space, which is not short of money, also approved Dr. Mikoyan's super space shuttle project, allowing Egypt Aerospace City to complete the first experimental aircraft before the end of next year.

Sen Shangzhe spoke first: "Dr. Mikoyan, I have already seen the plan. I don't know much about the design of the space shuttle, but if it is the design of the enhanced structure, then I can still provide some help."

Mikoyan nodded: "This is the most promising plan at present. If it succeeds, then we can start the alien colonization plan."

"Materials and personnel are initially satisfied, and our project can officially start."

During this time, they continued to refine various designs for the space shuttle.

"Then trouble you, our plan is very simple, that is to enlarge the scale of the space shuttle so that it can withstand the impact of the metal hydrogen explosion." Dr. Mikoyan said while projecting the concept model.

Of course, metal hydrogen can only be used as a one-time fuel, and there is no way to store it for a long time, so it can only be used in the stage of flying out of the atmosphere.

But looking at the various parameters of this plan, an engineer showed hesitation: "Can this thing really fly?"

"Okay!" Wu Zhi could only shrug his shoulders. He knew that these researchers were sometimes very stubborn.

"Is passivation of metallic hydrogen not considered at all?"

Although the metal hydrogen of Homo sapiens belongs to sub-state metal hydrogen, not complete metal hydrogen, its specific impulse is still 3.2 times that of ordinary liquid hydrogen and liquid oxygen engines, reaching 1297 seconds.

To run on the runway, the spacecraft must not be hung on the bottom, but can only be placed on the back of the space shuttle, so that the space shuttle can support the spacecraft.

Another system is the security system.

Considering the danger of metal hydrogen, Dr. Mikoyan decided to abandon the manned driving plan and adopt the unmanned driving mode after discussing with a group of colleagues.

Even the spacecraft is not intended to carry astronauts, who can first go to outer space on another launch vehicle, and then board the spacecraft from low Earth orbit.
