Chapter 271 Assumption of Orbital Accelerated Projection
"Commissioner Zhao, which one do you prefer?" the person from the aerospace institute asked carefully. From his heart, he prefers the second one. For astronauts, this kind of technology is worth a lot of money.
. With such technology, the service life of satellites can be increased at least several times. Many satellites are in low-Earth orbit. Such satellites have an orbital altitude of only a few hundred kilometers. In this space, it is not
In a true vacuum state, although some air particles are thin, they will still produce a certain amount of friction on the satellite at this altitude. Although this friction is very small, it will also reduce the speed of the satellite over time.
As the speed decreases, the satellite's orbit will decline. At this time, if certain measures are not taken, the satellite will gradually fall downward until it enters the atmosphere and is burned to ashes.
Therefore, all satellites in low-Earth orbit must carry a certain amount of fuel. When its speed drops to a threshold, the engine on the satellite will start to increase the speed of the satellite and maintain the orbit.
If there is a power system that does not require chemical fuel, and the orbit of the satellite can be maintained solely by relying on the satellite's battery panels, it will be a quantum leap.
This allows all aircraft in low-Earth orbit to significantly increase their mission time.
"To be honest, I prefer the second one, but I also tested the same device in the laboratory on the ground, but it didn't have such an effect at all." Zhao Ye said worriedly.
"That means that this kind of experiment must be conducted in outer space?"
"Well, that can only be the explanation. I even suspect that the test data I just got was disguised by Apocalypse. It has no reference value at all."
"If this is the case, then we have to develop manned spaceflight technology. If artificial intelligence is allowed to do this for such a long time, there is no chance that an accident like this will happen again." The person from the Aerospace Academy also frowned and said, this
The conclusion is not a happy one.
Manned spaceflight is not that fun. Not to mention burning money, it is just a step-by-step scientific experiment work, which cannot be completed in three to five years.
"Yes, I think so too. But I have an immature idea. Do you want to hear it?" Zhao Ye finally said what he wanted to say most today.
"Of course, we are interested in any of your opinions and ideas."
"That's right, I have a design, which is to use our superconducting technology to build an electromagnetic gun system that can launch non-living objects into space, or it is called an electromagnetic projection system." Zhao Ye said this and looked at it.
The astronauts present wanted to hear what their expressions were like.
"Commissioner Zhao, I don't quite understand. Do you mean to use electromagnetic cannons to shoot satellites into the sky?" The people at the Aerospace Academy had expressionless faces. This was not because they decided that the idea was ridiculous, but because they were shocked.
I don't know what expression to show.
"Well, that's about it."
"But no equipment can withstand such a high overload."
"That's okay. Let's make the acceleration process longer, such as fifty kilometers or one hundred kilometers. In this way, we can control the acceleration and prevent the overload of the projectile from being so great."
"Fifty kilometers? A fifty-kilometer gun barrel? How is this possible?"
"Nothing is impossible. We can build this gun barrel into an arc, so that it changes from the horizontal state at the beginning of the launch to the vertical state after the launch."
After finishing speaking, Zhao Ye also became excited. He stood up directly and led everyone to his laboratory. There, Zhao Ye had already made a small-scale model. Based on this model, according to the
According to his calculations, if it is built, it will be able to project more than ten tons of materials into outer space at one time.
Although people cannot be shot out, supplies can be shot up at will, which can save a lot of time in manned space projects.
Ten tons at a time, launched three or five times a day, it can catch up with the carrying capacity of a freight train.
What is the most important thing in developing aerospace? Materials, of course! When rocket launches are used, the funds consumed for items weighing one kilogram are calculated in units of tens of thousands. Under such circumstances, the aerospace engineering itself has received a huge
limit.
For example, in a space station, the walls may be only a few millimeters long, and then a variety of expensive materials are used to strengthen the strength of these few millimeters.
But with Zhao Ye's technology, it is very convenient. Is the warehouse wall too thin and unsafe? Then make it thicker! They can even have the luxury of using armored steel to make the outermost warehouse wall.
Of course, this is only one aspect. With this device, it will be very convenient to launch satellites and so on in the future. Thinking about such a technology, they feel excited. But excitement is excitement. Such a technology, think about it
It's incredibly complicated.
This is much more difficult than launching a rocket. The difficulty of rockets is nothing more than how to improve the efficiency of the engine and how to increase the diameter of the rocket. This involves mainly material issues. The relevant theories of rockets are already very mature.
.
However, this thing looks a bit unreliable. Although he is not the designer, as an expert, he can casually raise countless problems that need to be solved.
For example, how to solve the friction problem of projectiles? At such a high speed, just overcoming air resistance is a headache. Another example is how to solve the material problem? How much superconducting material is needed for such a large project?
Although he knew that the country already had a superconducting material that could be mass-produced, the output was really worrying.
If such a large project were to be built, it would require a massive amount of superconducting materials. At the current output rate, he wouldn't have to think about it before closing his eyes.
But looking at Zhao Ye's shining eyes, he inexplicably gained more confidence. Others may not be able to do it, but maybe the person in front of him can really create miracles.
"Commissioner Zhao, how much superconducting material do you think is needed for this device?" People from the Aerospace Academy asked the question they were most concerned about.
"Well, I have roughly calculated this. If we want to build a fifty-kilometer-long orbital accelerating ejection device, we will need at least fifty thousand tons of superconducting materials." Zhao Ye did not hold back and directly stated his estimated figure.
"Fifty thousand tons? I don't know how much our country produces in a year, but what I know is that our production has always been measured in kilograms. Think about this production, it doesn't necessarily mean how many tons a year, right?"
"Ha, this is not a problem. I have already thought of a way to solve it."
"What way?"
"Hey, keep it a secret!" Zhao Ye smiled unscrupulously. He definitely couldn't tell irrelevant people about this kind of thing.
