Homo sapiens

And the other side.

On the northern plateau of Motor Island.

Here is the highest peak of Mada Island - Mount Malumukutru, with a height of 2876 meters.

However, part of this mountain peak was flattened at this time, and a high-rise building was built in the flattened area.

The entire high-rise building almost wraps around the mountain peak, and its surface building height is 1,000 meters. At this time, the altitude of Malumukutru Mountain has reached 3,622 meters.

This is the location of Motor Island Space City, another space city invested by Homo Sapiens Company.

This base relied on the underground projects built here by the Homo sapiens company before. Through renovation and expansion projects, a large group of underground bases was quickly built.

As mentioned before, the technical route of Motor Island Space City is a mass projector, and there are no problems in terms of electromagnetic acceleration.

The real problem that plagues the mass projector is that the exit accelerates too fast. After hitting the dense atmosphere, friction heat, shock waves, derived infrasound waves, and sudden impact reaction force are generated.

Although the Homo sapiens company has developed special rocket engines, special satellites and special instruments and equipment that can withstand high loads in its previous Longgrand Cannon project.

However, the energy utilization rate of the Longgrand Cannon is actually not high. You must know that its propellant is submetallic hydrogen, which is more than ten times more powerful than TNT.

This is also the reason why the Harij Space City in North Africa can carry out projects.

The giant cannon launches the spacecraft because it can be launched quickly, without having to consider the weather or the like, and can directly lift off with brute force.

As for the mass projector project that Motor Island Space City is currently working on, its chief engineer Su Changli naturally does not want to continue the route of the Longgrand Cannon. He hopes to solve the conflict between the mass projector and the atmosphere.

Sam, the engineer responsible for designing the launch tower, spread his hands helplessly:

"Chief Engineer, the tower is already at its limit. Even if we use various new materials and a high-strength structure with a height of 1,000 meters, we basically cannot increase the height."

Su Changli didn't pay too much attention. After all, he had no intention of building a launch tower that could directly reach the Karmen Line.

Because this is unrealistic, even though new materials for Homo sapiens are emerging one after another, there is currently no material that can build a height of 100 kilometers.

The Malumukutru Mountain Tower has two main functions. One is to lay electromagnetic guide rails, and the other is to resist the pressure of the underlying atmosphere. Both the tower track and the underground ring track need to maintain a sub-vacuum.

Since the track's pipe radius is 50 meters, the atmospheric pressure it needs to withstand is very large, especially in the lower atmosphere.

Therefore, when building tall towers, mountains are chosen in order to increase the altitude of the hard building structure as high as possible.

Originally, the Nibala branch was more suitable for this project. After all, there are mountains more than 8,000 meters high there.

However, the safety of the Nibala area is not high, and it is very close to Tianzhu and the Far East. It does not have enough buffer hinterland and is not suitable for investment in such large-scale projects.

The Homo sapiens company does not want to continue to irritate these two neighbors, lest they jump over the wall.

Therefore, the mass projector project fell on the Motor Island Branch.

Su Changli turned his head and looked at another young man: "Baisha, what stage are you at?"

"The airship has been designed, and the three test airships can all fly to a height of 50,000 meters." Baisha called up the design concept model and directly projected it holographically.

This very huge airship is shaped like a donut with a radius of 3 kilometers. It is composed of 30,000 independent sub-airbags and uses helium as the airbag gas.

Su Changli only took a brief look at the airship. What he really cared about was the connecting pipe between the airship and the tower.

High towers and underground circular tracks are designed with hard pipes.

The pipeline between the airship and the tower is a flexible pipeline design. The requirements for this thing are very high, it must be very lightweight and have sufficient compressive strength.

"Where's the progress of the hose?"

"We already have a plan." Bai Sha moved his hand across the holographic projection, and the screen suddenly turned into a pipe with a radius of 50 meters.

He pointed to the pipeline and explained: “In order for the hose to maintain a sub-vacuum, two problems must be solved. One is that the pipeline must withstand the negative pressure of the atmosphere, and the other problem is the high-strength lightweight material with a length of 43,000 meters. "

Su Changli asked another question: "Hasn't the carbon nanotube laboratory produced results yet?"

Bai Sha shook his head: "No, they use biosynthesis technology. Although they have produced carbon nanotubes with a length of tens of meters, they have been unable to break through the length of a hundred meters because the material properties and biosynthesis are not suitable for this kind of carbon substance."

"Carbophilic properties of carbon-based organisms?"

Baisha nodded: "Yes, it is because of the carbon-philic nature that microorganisms can easily insert some hydrogen and oxygen into the carbon chain during the synthesis process, causing structural defects in the carbon nanotubes."

"Then how do you plan to solve the material problem?" Su Changli asked with a headache.

Baisha is confident about this: "Although carbon nanotubes cannot be used, modified hard spider silk and high-strength steel wire can replace carbon nanotubes, at least dozens of kilometers in length can be replaced."

"Steel wire? Isn't the weight too high? The weight of the airship is not high."

"Don't worry, the role of the steel wire in the cable is actually to enhance its upper limit of tensile strength, and the weight is only about 132 tons."

Su Changli took a look at the payload of the airship, which was 3,172 tons, and immediately felt relieved.

"In order to solve the problem of hose collapse in a sub-vacuum state, the hose must be in a taut state, and then 16 cables are used as the core, plus structural support rings one kilometer apart to ensure that the hose does not collapse."

"The material for the partition wall of the hose is a low-elastic, high-strength film. In addition, the steel wires in the cables and the metal structure support rings can be used as positioning targets for magnetic field radar to avoid contact between the spacecraft and the pipe wall during launch."

Su Changli touched his chin: "The spacecraft must not be too big. It is best to control the radius below 15 meters."

"As for the hose outlet of the ring-shaped airship, we will use a special disposable film so that the spacecraft can directly crash through it."

Disposable sealing film, this technology is not difficult, because America has a rotary cannon project using a large centrifuge, which also uses this method.

As for the airship hose, it was not the first creation of Homo sapiens. There is a similar project in Maple Leaf Country, but the project is still in the conceptual stage and has not attracted much investment.

Only the Homo sapiens company with deep pockets has the ability to invest in so many large-scale aerospace projects at the same time.

After some discussion, Su Changli finally sorted out the progress of each team. Judging from the current situation, their mass projector is just around the corner.

He said with satisfaction to everyone present: "Everyone, I have learned about the progress of each department. I now announce the official launch of the Dandelion project. I hope everyone will continue to work hard."

Bang bang bang! Everyone also applauded.

This mass projector, called Project Dandelion, has finally begun to accelerate into full gear.

As long as the airship and hoses are manufactured, and then the exclusive spacecraft design and manufacturing are completed, the project can begin actual testing.

The moment this flower in the sky blooms, it will surely shake the whole world.

Compared with the vast starry sky, human beings are too small.

Homo sapiens companies don't care at all about the constant closures of the great powers.

If we don't work hard to develop now, human beings will only be trapped and die on the earth, and then like the previous overlords of the earth, they will be annihilated in the long river of history.
