Here is the highest peak in Madagascar - 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 Malumukutlu Mountain has reached 3,622 meters.
This is the location of Madagascar Space City, another space city of Homo sapiens Company.
This base quickly built a large group of underground bases with the help of previous underground projects by Homo sapiens here.
As mentioned before, the technical route of the Madagascar 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 Homo sapiens has developed special rocket engines, special satellites and special instruments and equipment that can withstand high loads in its previous Longgrand Cannon project.
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.
Only Homo sapiens with deep pockets can afford to launch so many large-scale aerospace projects at the same time.
Baisha is confident about this: "Although carbon nanotubes cannot be used, modified hard spider silk plus high-strength steel wire can replace carbon nanotubes, at least dozens of kilometers in length can be replaced."
"Then how do you plan to solve the material problem?" Su Changli asked with a headache.
"The airship has been designed, and the three test airships can all fly to an altitude of 50,000 meters." Baisha called up the design concept model and directly projected it holographically.
"Chief Engineer, the tower is already at its limit. Even if we use a variety of new materials and a high-strength structure of 1,000 meters, we basically cannot increase the height."
"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."
As long as the airship and hoses are manufactured, and then the exclusive spacecraft design and manufacturing is completed, the project can begin actual testing.
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."
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.
Homo sapiens did not want to continue to irritate these two neighbors, lest they jump over the wall.
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 rails and the underground ring rails need to maintain a sub-vacuum.
This is also the reason why the Egyptian Space City can carry out projects.
"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.
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."
The reason why a giant cannon launches a spacecraft is because it can be launched quickly, without having to consider the weather and so on, and it can directly lift off with brute force.
Sam, the engineer responsible for designing the launch tower, spread his hands helplessly:
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.
"
After some discussion, Su Changli finally clarified the progress of each team. Judging from the current situation, their mass projector is just around the corner.
High towers and underground circular tracks are designed with hard pipes.
Su Changli touched his chin: "The spacecraft must not be too big. It is best to control the radius below 15 meters."
"Where's the progress on the flexible pipe?"
Therefore, when building tall towers, mountains are chosen in order to increase the altitude of the hard building structure as high as possible.
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.
As for the mass projector project currently being carried out in Madagascar Space City, its chief engineer Su Changli naturally does not want to continue to follow the route of the Longgrand Cannon. He hopes to solve the conflict between the mass projector and the atmosphere.
"Steel wire? Isn't the weight too high? The weight of the airship is not high."
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.
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 mass projector, named Project Dandelion, has finally begun to enter a state of full acceleration.
Su Changli took a look at the payload of the airship, which was 3172 tons, and immediately felt relieved.
So the mass projector project fell to the motor area.
Su Changli didn't pay too much attention, after all, he had no intention of building a launch tower that could directly reach the Karman Line.
"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."
"As for the material of the hose's partition wall, a low-elastic and high-strength film is used. In addition, the steel wire in the cable and the metal structure support ring can be used as the positioning target of the magnetic field radar to avoid contact between the spacecraft and the pipe wall during launch."
Su Changli turned to look at another young man: "Baisha, what stage are you at?"
The moment this flower in the sky blooms, it will surely shake the whole world.
“Are carbon-based organisms carbophilic?”
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.
However, Nibala's security is not high and it is very close to Tianzhu and the Far East. It does not have enough strategic hinterland and is not suitable for this kind of project.
"In order to solve the problem of hose collapse in a sub-vacuum state, the hose must be in a tight 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."
Disposable sealing film, this technology is not difficult, because America has a rotary cannon project using a large centrifuge, which also uses this method.
Originally, the Niphara side was more suitable for this project, after all, there are mountains over 8,000 meters high there.
Since the orbit's pipe radius is 50 meters, the atmospheric pressure it needs to withstand is very large, especially in the lower atmosphere.
Su Changli asked another question: "Hasn't the carbon nanotube laboratory produced results yet?"
Bang bang bang! Everyone also applauded.
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."
Compared with the vast starry sky, human beings are too small.
Homo sapiens don't care at all about the constant closing of doors by 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.
