Many people's eyes widened when they heard that the plan that Dayang Group announced a few years ago was finally realized.
Shen Minghai opened the document and displayed a device similar to an aeroengine. However, if you only look at the appearance, you can only see that it is more complicated than an ordinary aeroengine. No matter how much it is, it will be difficult to see.
Shen Minghai opened his notes again and began to explain:
"For a better understanding, before talking about plasma engines, let us first review the current main engine technologies.
First of all, it is the steam turbine. This is the first power equipment produced by Dayang Group. From then on, 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., steam turbines are still used in some trains. Steam turbines mainly provide power for heavy equipment.
Secondly, there is the internal combustion engine. The internal combustion engine is the second engine developed by Dayang Group.
The invention of the internal combustion engine is also a little special, because the person who invented the internal combustion engine was not the main scientific researchers of Dayang Group at that time, but the maids around Mrs. Zhou. Of course, they are now 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 the leader in current civilian technology.
The third is the aero engine. The aero engine has multiple technologies. The most representative one at present is the axial flow turbojet engine, which is also a technology commonly used in aviation aircraft. Whether it is a civilian passenger aircraft or a military fighter, most of them use this type of engine.
technology.
The fourth type of engine is the rocket engine. Rocket engines are mainly used in missiles. Secondly, they are also very useful in current starry sky exploration. In fact, the rocket engine itself was invented to get rid of the gravity of Tianyuan Star. It is just because the gravity of Tianyuan Star is too strong.
Large, exceeding the limits of chemical fuels.
The fifth type is the electric motor. This is also the key technology in current development. In many fields, it can even replace the internal combustion engine. 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 above four engines
, all 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., which are developed on 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 with traditional engines, the internal core temperature of plasma engines 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.
Under such high temperatures, even formations and other methods are no longer stable.
In order to constrain and control such high temperatures, we developed a technology called 'electromagnetic vortex'. This technology was inspired by observing and studying the 'prominences' on the sun, combined with the tornadoes on the Tianyuan star.
Under certain conditions, the electromagnetic field will spin wildly like a tornado, absorbing all the energy around it and trapping high temperature inside it. In the current laboratory environment, the maximum temperature in the center of the electromagnetic vortex can reach 100,000 degrees, and the temperature can be controlled
Around 30,000 degrees.
But the most stable and easiest to control temperature point is 12,000 degrees. No matter how low the temperature is, the electromagnetic vortex will be unstable and may not even be formed.
At 12,000 degrees, when the spin speed is 60,000 to 180,000 revolutions per second, a stable electromagnetic vortex can be formed, with a stable length of about 5 meters. The interior can even be heated by a magnetic field, increasing the
Thermal efficiency, accelerating working fluid.
Under experimental conditions, the jet speed of the electromagnetic vortex can reach 0.1 times the speed of light. In other words, with such a powerful effect, the speed of the plasma engine can theoretically reach 0.1 times the speed of light. And this is only the current technology. In the future
, the plasma engine will also have great potential to be tapped."
"The above is the working principle. Let's talk about the three plasma engines currently being studied.
The first is pure plasma technology. The working fluid of plasma is pure water. Under certain high temperature, high pressure and super strong electromagnetic field, water will decompose into negatively charged oxygen ions and positively charged hydrogen ions.
Ions will form a double helix cyclone inside hydrogen and outside oxygen in an electromagnetic field environment.
Any ultra-high-temperature charged particle aggregate is actually plasma, which can be understood as paste; however, the temperature of this paste is a bit high and a bit skinny.
After being accelerated by the magnetic field, it is finally ejected from the rear of the engine, forming a powerful reaction force.
The second type is a turboplasma engine. The plasma needs to be discharged after working through the engine blades. It is more efficient, but the disadvantage is that it is limited by the turbine, which currently can only achieve a maximum thrust of 50 tons.
The third type is a hydrogen-oxygen fuel turbine plasma engine. It has a front combustion chamber, similar to the structure of an aircraft engine, where hydrogen and oxygen are burned to generate the first power; then high-temperature water vapor enters the plasma reaction area and enters the turbine
area, do the work again.
The first technology is the simplest and most reliable, and can achieve a thrust of 200 tons; but the efficiency is the lowest, with a thermal efficiency of less than 40%. The first technology can be large or small, and the small one can reach 0.2 meters, 10 kilograms
The thrust force is as large as four meters and 200 tons of thrust.
The second technology is more complex and reliable. The current mature technology has a thrust of 50 tons; the thermal efficiency can reach 68%.
The third technology is more complex, difficult to maintain, has high technical requirements, and is slightly less stable; 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 energy to provide huge electricity. Because the nuclear island is relatively bulky and the overall structure has a low thrust weight, the plasma engine still cannot be used on the ground and can only be used in space.
At present, we mainly use the plasma engine of the second technology, supplemented by the first technology.
In the future, we will continue to research better plasma engines and nuclear fusion energy technology. We will strive to realize an aerospace vehicle that can take off from the ground as soon as possible.
Now, Dayang Group has already rolled out a batch of Class B technology, that is, second-class technology plasma engines, which will soon be used to assemble spacecraft and prepare to be used to move planets in the asteroid belt."
After Shen Minghai finished speaking, everyone was still in a daze.
Everyone present is basically tech-savvy. Maybe they didn’t understand technology before, and some even rejected it. But now, after seeing the power of space-age technology, they have begun to immerse themselves in researching technology.
Being exposed to technology for a long time even has a by-passing effect on cultivation. It was only then that everyone gradually understood what the secrets that Dayang Group had hidden were - learning, education, thinking, and scientific understanding of the world.
Therefore, everyone knows what a high temperature of 12,000 degrees means. Even the current powerful formations will be burned through, and magical powers and spells will fail because they exceed the limit. Those strange fires on the ground, at such a temperature, are gentle
Like a candle.
Shen Minghai called up another video, which was a test video of the plasma engine, but it was used to test the tail flame. The light blue, almost imperceptible tail flame sprayed out for tens of meters, and a steel rod as thick as an arm was inserted into the tail flame.
, only to see the iron rod evaporating as quickly as a popsicle.
During this process, the iron rod didn't even have time to turn red before it was directly evaporated.
Seeing this picture, many people feel numb: the technology of Dayang Group is getting more and more amazing. This technology has surpassed Xuanhuang Civilization in some fields. At least, Xuanhuang Civilization does not seem to have plasma technology.
After a while, the prince of the Song Dynasty, Zhao Guoyin, suddenly spoke: "This plasma technology sounds very powerful. So, can it accelerate the Tianyuan Star?"
"Huh?" Shen Minghai was a little dazed. We were talking about an asteroid, why did it suddenly turn to Tianyuan Star?
But Zhang Hao understood clearly, "The prince means to let Tian Yuan Xing escape directly?"
"Yes! Mr. Zhang's reaction is quick!" Zhao Guoyin was overjoyed and looked at Zhang Hao expectantly: Come and praise me now.
However, Zhang Hao shook his head: "The prince's idea is good. But there are several problems that need to be solved.
First, once we escape the star system, where will the sunlight the planet needs come from? Without sunlight, the entire world will wither and freeze in half a year at most.
Second, Tianyuan Star has a diameter of 128,700 kilometers and a mass a thousand times that of Venus. How much thrust is needed to push such a huge planet into space? What is the speed? Can it escape the pursuit of the Red River Civilization?
Third, Tianyuan Star’s life itself only has about 14,000 years left. What will happen after 14,000 years? 14,000 years sounds very long, but now the theoretical lifespan of Master Dongxu is five thousand years. After three generations
,what to do?"
"Uh..." Zhao Guoyin was dumbfounded by Zhang Hao's three questions.
Sure enough, you can't be slapped on the head for anything. The consequence of being slapped on the head is to be slapped in the face.
At this time, Bai Yutang, the general manager of Dayang Group, also spoke, "Do you still remember the original video of Xuanhuang Civilization? When they escaped, they also used spaceships, not planets.
If it were science fiction, then I'd say it's a brilliant idea.
But if it is a real society, we can only think about it.
The planet has a large target, poor defense, is easy to attack, and the structure is loose and easy to disintegrate. Even if you want to install an engine, you don't know where to install it. Based on the thrust of the plasma engine, if it is installed on the ground for a long time, it will cause the earth's crust to collapse.
This will lead to a global disaster.
Also, the planet is too huge and has a strong gravity, so the engine's tail flame may be pulled back before it can fly out of the planet's gravity. In that case, the engine would be meaningless.
According to the current calculations of the Ocean Group, the maximum diameter of the spacecraft cannot theoretically exceed 500 kilometers. Five hundred kilometers is the limit of hydrostatic equilibrium. Without rotation, the celestial body will tend to be more perfect after a long enough time.
spherical shape. But in fact, this trend will occur when the diameter of the object exceeds 400 kilometers.
Once the volume is too large and damaged, the spacecraft will collapse on itself.
The spaceship is like this, the planet...but it can be used to shoot a movie of the planet escaping."
Prince Zhao Guoyin touched the tip of his nose awkwardly, "Then I support the plan to transform Venus."
