Plasma engine?
I heard that the plan that the Ocean Group had shouted a few years ago was finally realized, and many people had their eyes widened.
Shen Minghai opened the document and showed a device similar to an aircraft engine. However, if you only look at the appearance, you can only see that it is more complicated than the general aero engine, and it is difficult to see any more.
Shen Minghai opened his notes again and began to explain:
"For a better understanding, before talking about plasma engines, let us review the current main engine technologies.
First, there is the steam turbine. This is the power equipment originally produced by the Ocean Group, and since then we have our own power.
Today, it is also one of the most widely used power equipment in the world. From ships, to industrial production, power equipment, mining, etc., even some trains still use steam turbines. Steam turbines mainly provide power for heavy equipment.
Secondly, the internal combustion engine. The internal combustion engine is the second engine developed by the Ocean Group.
The invention of the internal combustion engine is also a little special, because it was not the main scientific research personnel of the Ocean Group that invented the internal combustion engine at that time, but the maidservant beside Mrs. Zhou. Of course, now they are the heads of important departments.
The internal combustion engine is an important power source for small and medium-sized equipment such as automobiles and construction machinery. It has also entered every household and is a leader in current civil technology.
The third is the aero engine. Aeroengines have multiple technologies, and the most representative one at present is the axial turbojet engine, which is also a technology commonly used in aeroplanes. Whether it is a civilian passenger plane or a military fighter, most of this technology is used.
The fourth engine is the rocket engine. Rocket engines are mainly used in missiles. Secondly, it is also very useful in the current exploration of the starry sky. In fact, the rocket engine itself was invented to get rid of the gravity of Tianyuanxing. Just because the gravity of Uranus is too great to exceed the limit of chemical fuel.
Fifth, the motor. This is also a key technology for current development. It can even replace internal combustion engines in many fields. But unlike the above four, the electric motor needs to consume electric energy, and the electric energy needs to be provided additionally. In contrast, the four engines mentioned above can generate power independently.
The above five engine technologies can be regarded as a simple review of past engine technologies. In addition, there are some gas turbines, propeller engines, etc., all developed from the above five technologies.
Today, we are going to introduce the sixth power technology, which is also one of the most difficult power technologies to study. That is, the plasma engine. "
"Compared to traditional engines, the internal core temperature of a plasma engine can reach... 12,000 degrees! Yes, 12,000, which is twice as high as the surface temperature of the sun. No known material can withstand this temperature. At such a high temperature, the continuous array method and other means are no longer stable.
In order to restrain and control such high temperature, we have developed a technology called'Electromagnetic Vortex'. This technique is still inspired by observing and studying the ‘prominence’ on the sun, combined with tornadoes on Uranus.
Under certain conditions, the electromagnetic field will spin like a tornado, will absorb all the energy around, and bind the high temperature inside. In the current laboratory environment, the maximum temperature of the electromagnetic vortex center can reach 100,000 degrees, and the controllable temperature is about 30,000 degrees.
But the most stable and easiest temperature point is 12,000 degrees. No matter how low the temperature is, the electromagnetic vortex is unstable or even unable to form.
At 12,000 degrees and a spin speed of 60,000 to 180,000 revolutions per second, a stable electromagnetic vortex can be formed with a stable length of up to about 5 meters. The inside can even be heated by means of a magnetic field, improving thermal efficiency and accelerating the working medium.
Under the test conditions, the jet velocity of the electromagnetic vortex can reach 0.1 times the speed of light. That is to say, with such a powerful effect, the speed of the plasma engine can theoretically reach 0.1 times the speed of light. And this is just the current technology. In the future, plasma engines will have great potential. "
"The above is the working principle. Let me talk about the three plasma engines currently under study.
The first is pure plasma technology. The working fluid of plasma is pure water. Under certain high temperature, high pressure and strong electromagnetic field, water will decompose into negatively charged oxygen ions and positively charged hydrogen ions. These two ions will form a double-helix cyclone inside and outside hydrogen under the electromagnetic field environment.
And any ultra-high temperature, charged particle polymer is actually a plasma, which can be understood as a paste; however, the temperature of this paste is a little high and a bit skinny.
After the acceleration of the magnetic field, it finally ejected from the rear of the engine, forming a strong reaction force.
The second type is the turbo-plasma engine. The plasma needs to be discharged after doing work through the engine blades. The efficiency is higher, but the disadvantage is that it is limited by the turbine. At present, it can only achieve a maximum thrust of 50 tons.
The third type is the oxyhydrogen fuel plasma engine. It has a front combustion chamber, similar to the structure of an aero engine, where hydrogen and oxygen are burned to produce the first power; then high-temperature water vapor enters the plasma reaction zone, enters the turbine zone, and performs work again.
The first technology, the simplest and most reliable technology, can achieve 200 tons of thrust; but the lowest efficiency, the thermal efficiency is only less than 40%. The first technology can be large or small, small can achieve 0.2 meters, 10 kg of thrust, large can achieve four meters, 200 tons of thrust.
The second technology is more complex and reliable. The current mature technology is 50 tons of thrust; the thermal efficiency can reach 68%.
The third technology is more complicated, difficult to maintain, has high technical requirements, and has slightly poor stability; but the thrust can reach 80 tons and the thermal efficiency can reach 86%!
The last three technologies all require pure water as the working fluid, and all require nuclear power to provide huge power. Because the nuclear island is relatively bulky and the overall structural weight is relatively low, the plasma engine can still not be used on the ground, only in space.
At present, we mainly use the plasma engine of the second technology, supplemented by the first one.
We will continue to study better plasma engines and nuclear fusion energy technologies in the future. Strive to realize the air and space vehicles that can take off on the ground as soon as possible.
Today, the Ocean Group already has a number of Class II technology, which is the plasma engine of the second-class technology, which will be used to assemble the spaceship and prepare to move the planet in the asteroid belt. "
Shen Minghai is finished, everyone is still in a daze.
Everyone on the scene basically knows technology. Perhaps they did not understand technology before, and some people even rejected it; but now that they have seen the power of the space age technology, they have begun to dig into technology.
Long-term exposure to technology even has a bypass effect for repairs. It was only at this time that everyone gradually understood what the secret that Ocean Group once hid-learning, education, thinking, and scientific understanding of the world.
Therefore, everyone knows exactly what the high temperature of 12,000 degrees means. Even the current powerful formations will be burned through, and magical spells will fail because they exceed the limit. Those strange fires on the ground are soft like candles at this temperature.
Shen Minghai called up another video, which is a test video of a plasma engine, but only for the tail flame test. A pale blue, almost imperceptible tail flame spewed out for tens of meters, and a thick steel rod with an arm extended into the tail flame, only to see that the iron rod quickly evaporated like an ice stick.
In this process, the iron rods were even too late to turn red, and they were directly evaporated.
Seeing this picture, many people feel that the scalp is numb: The technology of the Ocean Group is becoming more and more demon. This technology has already exceeded Xuanhuang civilization from certain fields. At least, Xuanhuang civilization does not seem to have plasma technology.
For a while, Zhao Guoyin, the crown prince of the Song Dynasty, suddenly said: "This plasma technology sounds very powerful. So, can you accelerate Tianyuanxing?"
"Huh?" Shen Minghai was a little dazed. We're talking about asteroids, how did they suddenly turn to Uranus?
But Zhang Hao understood, "The Prince meant to let Tian Yuanxing escape directly?"
"Yes! Or Mr. Zhang responds quickly!" Zhao Guoyin was overjoyed, looking at Zhang Hao expectantly: Come and praise me.
However, Zhang Hao shook his head: "Prince's idea is good. But there are several problems to be solved.
First, once we escape from the galaxy, where does the sunlight the planet needs get from? Without sunlight, the whole world will wither and freeze in half a year.
The second is that the diameter of Uranus is 128,700 kilometers, and its mass is a thousand times that of Venus. How much thrust is needed to push such a huge planet into space? How much is the speed, can you escape the pursuit of the Red River civilization?
The third, the life of Uranus, is about 14,000 years left. What to do after 14,000 years? 14,000 years sounds very long, but now the theoretical life span of Dongxu masters is 5,000 years. After three generations, what should I do? "
"Ah..." Zhao Guoyin was dumbfounded by Zhang Hao's three questions.
Sure enough, you can't pat your head on anything. The consequence of patting your head is to be beaten.
At this time, Bai Yutang, the general manager of the Ocean Group, also said, "Remember the original video of the Xuanhuang civilization. When they fled, they used the spaceship instead of the planet.
If it is a science fiction work, then I want to say that this is a wonderful idea.
But if it is a real society, we can only think about it.
The planet has large targets and poor defenses, and is easy to be attacked. The loose structure is easy to disintegrate. Even if you want to install the engine, you don’t know where to install it. Calculated by the thrust of the plasma engine, if it is installed on the ground for a long time, it will cause the crust to collapse, which will lead to a global disaster.
Also, the planet is too large, and the gravity is too large. The tail flame of the engine may not be able to fly out of the gravity of the planet before it is pulled back. In that case, the engine is meaningless.
According to current calculations by the Ocean Group, the maximum diameter of the spacecraft should not exceed 500 kilometers in theory. Five hundred kilometers is the limit of hydrostatic balance. In the absence of rotation, celestial bodies will tend to be more perfect spherical after a long enough time. But in fact, this trend will occur when the celestial body exceeds 400 kilometers in diameter.
Once the volume is too large, the spacecraft will collapse itself after being injured.
This is still true for spaceships, planets... but it is possible to make a movie of planet escape. "
Crown Prince Zhao Guoyin touched the tip of his nose awkwardly, "Then I support the transformation of Venus."
