Chapter 1069 Escape Plan?

Plasma engine?

Many people's eyes widened when they heard that the plan that Dayang Group had shouted out a few years ago had finally come true.

Shen Minghai opened the document, showing 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 ordinary aero engines, and it is difficult to see if there are 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, the steam turbine. This is the first power equipment produced by Dayang Group, and we have our own power since then.

Today, it is also one of the most widely used power equipment in the world. From ships, to industrial production, power equipment, mining, etc., and even some trains still use steam turbines. Steam turbines, primarily for powering heavy equipment.

Second, 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 it was not the main scientific research personnel of the Dayang Group who invented the internal combustion engine at that time, but the maid next to 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 entered every household and is the current leader in civilian technology.

The third is the aero engine. There are multiple technologies for aero-engines, and 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 airliner or a military fighter jet, most of them use this technology.

The fourth engine is the rocket engine. Rocket motors 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 the Tianyuan star. It's just because the gravitational force of Tianyuan star is too great, which exceeds the limit of chemical fuel.

The fifth type is the electric motor. This is also the key technology of current development. It can even replace internal combustion engines in many fields. But unlike the above four, the motor needs to consume electric energy, and the electric energy needs to be provided additionally. In contrast, the above four engines can generate power independently.

The above five engine technologies can be regarded as a brief review of past engine technologies. In addition, there are some gas turbines, propeller engines, etc., which are all developed on the basis of the above five technologies.

Today, we are going to introduce the sixth power technology, which is also one of the most difficult power technology 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 degrees, which is twice as hot as the sun's surface. No known material can withstand this temperature. At such a high temperature, even the array and other means are no longer stable.

In order to confine and control such high temperatures, we have developed a technology called 'electromagnetic vortex'. This technique was inspired by observing and studying the sun's prominence, combined with the tornado on the Tianyuan star.

Under certain conditions, the electromagnetic field will rotate crazily like a tornado, absorbing all the energy around it, and trapping high temperature inside it. Under the current laboratory environment, the maximum temperature at the center of the electromagnetic vortex can reach 100,000 degrees, and the controllable temperature is about 30,000 degrees.

But the most stable and easiest temperature point to control is 12,000 degrees. No matter how low the temperature is, the electromagnetic vortex will be unstable or even impossible 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, and its stable length can reach about 5 meters. Its interior can even be heated by means of a magnetic field to improve thermal efficiency and accelerate working fluid.

Under the experimental conditions, the ejection speed 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 that's just the current technology. In the future, plasma engines will have great potential to be tapped. "

"The above is the working principle. Let's talk about the three plasma engines currently under study.

The first is pure plasma technology. The working medium of plasma is pure water. Under certain high temperature and high pressure and super strong electromagnetic field, water will decompose into negatively charged oxygen ions and positively charged hydrogen ions, and these two ions will form a double helical cyclone with hydrogen inside and oxygen outside under the environment of electromagnetic field.

And any ultra-high-temperature, charged particle aggregate is actually plasma, which can be understood as paste; but 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 strong reaction force.

The second type is a turbo plasma engine, and the plasma needs to be discharged after the blades of the engine do work. It is more efficient, but the disadvantage is that it is limited by the turbine, and currently it can only achieve a maximum thrust of 50 tons.

The third is the hydrogen-oxygen fuel turbo plasma engine. It has a front combustion chamber, similar to the structure of an aero engine, where hydrogen and oxygen are burned to generate the first power; then high-temperature water vapor enters the plasma reaction area, enters the turbine area, and does work again.

The first technology is the simplest and most reliable, and can achieve a thrust of 200 tons; but it has the lowest efficiency, with a thermal efficiency of less than 40%. The first technology can be large or small. The small one can achieve a thrust of 0.2 meters and 10 kilograms, and the large one can achieve a thrust of four meters and 200 tons.

The second technology is more complicated and more 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, high technical requirements, and 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 a working medium, and all require nuclear energy to provide huge power. And because the nuclear island is relatively bulky and the thrust of the overall structure is relatively low, 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 study better plasma engines and nuclear fusion energy technology. Strive to realize an aerospace vehicle that can take off from the ground as soon as possible.

Now Dayang Group already has a batch of plasma engines with B-level technology, that is, the second-level technology, coming off the production line, which will be used to assemble spacecraft and prepare to move planets in the asteroid belt. "

After Shen Minghai finished speaking, everyone was still in a daze.

Everyone at the scene basically understands technology. Maybe they didn't understand technology before, and some people even rejected technology; but now, after seeing the power of space age technology, they all start to study technology.

Long-term exposure to technology can even have a bypassing effect on cultivation. It was only at this time that everyone gradually understood what the secret that Dayang Group had hidden was - 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 formation will be burned through, and supernatural powers and spells will become invalid because they exceed the limit. The strange flames on the ground are as gentle as candles at such a temperature.

Shen Minghai called up another video, which was a test video of the plasma engine, but it was only for testing the tail flame. A light blue, almost imperceptible tail flame sprayed out tens of meters, and a steel rod as thick as an arm was inserted into the tail flame, only to see that the iron rod quickly evaporated like a popsicle.

During this process, the iron rod was vaporized before it even turned red.

Seeing this scene, many people feel their scalps go numb: Dayang Group's technology is becoming more and more bewitching. This technology has already surpassed Xuanhuang civilization in some fields. At least, Xuanhuang civilization does not seem to have plasma technology.

After a while, Zhao Guoyin, the crown prince of the Song Dynasty, suddenly said, "This plasma technology sounds very powerful. Then, can it speed up the Tianyuan star?"

"Huh?" Shen Minghai was a little dazed. We are talking about asteroids, why did they suddenly turn to the Tianyuan star?

But Zhang Hao understood, "The prince means to let Tianyuanxing escape directly?"

"Yes! Mr. Zhang reacted quickly!" Zhao Guoyin was overjoyed, and looked at Zhang Hao expectantly: Hurry up and praise me.

However, Zhang Hao shook his head: "The prince's idea is good. But there are a few problems that need to be resolved.

First, once we escape the star system, where will the sunlight that the planet needs come from? Without sunshine, the whole world will wither and freeze for half a year at most.

The second one, Tianyuanxing, has a diameter of 128,700 kilometers and a mass a thousand times that of Venus. How much thrust would it take to push such a massive planet into space? How fast is it? Can it escape the pursuit of the Red River Civilization?

The third one, the life itself of Tianyuan star, has only about 14,000 years left. What will happen after 14,000 years? 14,000 years sounds like a long time, but the theoretical lifespan of a Dongxu master is five thousand years. After three generations, what should we do? "

"Eh..." Zhao Guoyin was dumbfounded by Zhang Hao's three questions.

Sure enough, nothing can be slapped on the head, and the consequence of slapping the head is to be slapped in the face.

At this time, Bai Yutang, the general manager of Dayang Group, also said, "Do you still remember the original video of Xuanhuang Civilization? When they escaped, they also used spaceships instead of planets.

If it's sci-fi, then I'd say it's a brilliant idea.

But if it is a real society, you can only think about it.

Planetary targets are large, poorly defended, easy to be attacked, loose in structure and 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 earth's crust to collapse, and then cause a global disaster.

In addition, the planet is too large and has a strong gravitational force. The tail flame of the engine may be pulled back before it can fly out of the planet's gravity. In that case, the engine doesn't make sense either.

According to Dayang Group's current calculations, the maximum diameter of the spacecraft should theoretically not exceed 500 kilometers. 500 kilometers is the limit of hydrostatic balance. When there is no rotation, the celestial body will tend to a relatively perfect spherical shape after a long enough time. But in fact, when the object exceeds 400 kilometers in diameter, this tendency will appear.

Once the volume is too large, the spacecraft will collapse by itself after being damaged.

The spaceship is still like this, the planet... But it is possible to shoot a video of a planet escaping. "

Prince Zhao Guoyin touched the tip of his nose in embarrassment, "Then I support the plan to transform Venus."
