Plasma engine?

Hearing that the plan shouted by Dayang Group a few years ago has finally come true, many people's eyes widened.

Shen Minghai opened the document and showed a device similar to an aero engine. However, if you only look at the appearance, you can only see that it is more complex than ordinary aero engines, 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's review the current major engine technologies.

First of all, there are steam turbines. This is the power equipment originally produced by Dayang 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., and even some trains still use steam turbines. Steam turbines, which primarily power 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 invention of the internal combustion engine was not the main scientific researchers of Dayang Group at that time, but the maid next to Mrs. Zhou. Now, of course, 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 the leader of current civilian technology.

Third, there are aero engines. Aero engines have multiple technologies, and the most representative one is the axial turbojet engine, which is also the technology commonly used in aero aircraft. Whether it is a civilian airliner or a military fighter, most of them use this technology.

The fourth type of 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 gravitational pull of the Tian Yuan Star. It's just that the gravitational pull of Tian Yuan Star is too great, exceeding the limit of chemical fuels.

Fifth, electric motors. This is also the key technology for current development. In many fields, it can even replace internal combustion engines, for example. But unlike the above four, the electric motor needs to consume electrical energy, and the electrical energy needs to be provided additionally. In contrast, all four engines can generate power independently.

The above five engine technologies can be seen 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 to study. That is, the plasma engine. ”

"Compared with conventional engines, the internal core temperature of plasma engines can reach ...... 12,000 degrees! Yes, 12,000, twice as much as the surface temperature of the sun. No known material can withstand such temperatures. In such high temperatures, even the formation 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 the observation and study of the 'sun' on the sun, combined with the tornadoes on the celestial element.

Under certain conditions, the electromagnetic field will spin wildly like a tornado, absorbing all the energy around it and confined the heat inside it. At present, in the laboratory environment, the maximum temperature of 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 easy-to-manipulate temperature point 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. The interior can even be heated by a magnetic field to improve thermal efficiency and accelerate the working fluid.

Under test conditions, the jet speed of the electromagnetic vortex can reach 0.1 times the speed of light. That is, 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, the plasma engine will also have great potential. ”

"That's how it works. Let's talk about the three types of plasma engines that are currently being studied.

The first is pure plasma technology. The working fluid of plasma is pure water. Under a certain high temperature and high pressure and super electromagnetic field, water will decompose into negatively charged oxygen ions and positively charged hydrogen ions, which will form a double helix cyclone inside and outside oxygen in the electromagnetic field environment.

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 a magnetic field, it is finally ejected from the rear of the engine, forming a strong reaction force.

The second type is the turbo plasma engine, which needs to be discharged after the work done by the engine blades. The efficiency is higher, but the disadvantage is that it is limited by the turbine, and the current maximum thrust can only be achieved by 50 tons.

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

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

The second technology, which is more complex and reliable, is currently mature and has a thrust of 50 tons and a thermal efficiency of up to 68%.

The third technology is more complex, difficult to maintain, has high technical requirements, and has slightly worse stability, but the thrust can reach 80 tons, and the thermal efficiency can reach 86%!

The last three technologies all require pure water as working fluid, and both require nuclear power to provide huge amounts of electricity. Because the nuclear island is relatively bulky and the overall structure thrust weight is relatively low, the plasma engine still cannot be used on the ground, but can only be used in space.

At present, we mainly use the second technology of plasma engine, supplemented by the first one.

In the future, we will continue to research better plasma engines and nuclear fusion energy technology. Efforts should be made to realize an aerospace vehicle that can take off from the ground as soon as possible.

Now, the Ocean Group has a batch of plasma engines with Class B technology, that is, Class II technology, coming off the assembly 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.

The people at the scene are basically tech-savvy. Maybe they didn't understand technology before, and some even rejected it, but now that they see the power of space age technology, they are all immersed in research.

Long-term exposure to technology even has a contact bypass effect on cultivation. It was only at this time that everyone gradually understood what the secret of the Ocean Group was - learning, education, thinking, and scientific understanding of the world.

Therefore, everyone knows what it means to have a high temperature of 12,000 degrees. Even the current powerful formations will be burned through, and the supernatural spells will be invalidated because they exceed the limit. The strange fires on the ground, at such temperatures, are as gentle as candles.

Shen Minghai called up another video, which was a test video of a plasma engine, but it was a test of the tail flame. The pale blue, almost imperceptible tail flame erupted for dozens of meters, and an arm-thick steel rod reached into the tail flame, only to see the iron rod evaporate as quickly as a popsicle.

In this process, the iron rod was directly evaporated before it even had time to turn red.

Seeing this picture, many people feel that their scalp is numb: the technology of Dayang Group is becoming more and more demonic. This technology has surpassed the Xuanhuang civilization in some fields. At least, the Xuanhuang civilization doesn't seem to have plasma technology.

After a while, Zhao Guoyin, the crown prince of the Song Dynasty, suddenly spoke: "This plasma technology sounds very powerful. Then, can you speed up the Tian Yuan Star?"

"Huh?" Shen Minghai was a little stunned. We're talking about the asteroid, why did it suddenly turn to the Tianyuan Star?

But Zhang Hao understood, "What does the prince mean, is it to let Tian Yuanxing escape directly?"

"Yes! Or Mr. Zhang's quick response!" 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 several issues that need to be addressed.

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

The second, the Tianyuan Star has a diameter of 128,700 kilometers and a mass 1,000 times that of Venus. How much thrust is needed to push such a huge planet into space, and how fast is it, and can it escape the pursuit of the Red River civilization?

The third, the life of the Tian Yuan Star itself, has about 14,000 years left. What to do in 14,000 years? 14,000 years sounds like a long time, but now the theoretical lifespan of the Cave Void Master is 5,000 years. After three generations, what will we do?"

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

Sure enough, you can't pat your head on anything, and the consequence of slapping your head is to be slapped in the face.

At this time, Bai Yutang, the general manager of Dayang Group, also spoke, "Do you remember the original video of the Xuanhuang Civilization, when they fled, they also used spaceships, not planets.

If it's science fiction, then I'd say it's a brilliant idea.

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

The planet has large targets, poor defense, is easy to attack, and has a loose structure that is easy to disintegrate. Even if you want to install the engine, you don't know where to install it. Based on the thrust of a plasma engine, installing it on the ground for a long time can lead to the collapse of the earth's crust, which in turn will lead to a global catastrophe.

There are also planets that are too large and gravitationally strong, and the tail flame of the engine may not be able to fly out of the planet's gravity before it is pulled back. In that case, the engine doesn't make sense.

According to the current calculations of the Ocean Group, the maximum diameter of the spacecraft, theoretically, cannot exceed 500 kilometers. 500 kilometers is the limit of hydrostatic equilibrium, and the celestial body will tend to be relatively perfect spherical after a long enough time without rotation. But in reality, this trend occurs when the diameter of the celestial body exceeds 400 km.

Once it is too large and damaged, the ship will collapse on its own.

The ship is still like this, the planet ...... But it's possible to make a planet escape film. ”

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