Plasma engine?
¡°When I heard that the plan that Dayang Group announced a few years ago was finally realized, many people¡¯s eyes widened.
Shen Minghai opened the document and displayed a device similar to an aerospace engine. However, if you only look at the appearance, you can only tell that it is more complex than ordinary aero engines. No matter how much more, 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 review the current main engine technologies.
First, there is the steam turbine. This was the first power equipment produced by Dayang Group, and from then on we had 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 researcher of Dayang Group at that time, but the maid next to Mrs. Zhou. Of course, they are now heads of important departments.
Internal combustion engines are important power sources 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.
Third, it is the aviation engine. Aviation engines have 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 jet, 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 current starry sky exploration. In fact, the rocket engine itself was invented to escape the gravity of Tianyuan Star. It's just because Tianyuan Star's gravity is too great and exceeds the limit of chemical fuel.
The fifth type is the electric motor. This is also the key technology in current development. In many fields it can even replace internal combustion engines. But unlike the above four types, the electric motor needs to consume electrical energy, and the electrical energy needs to be provided additionally. In contrast, the above four engines can all 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 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, 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 restrain and control such high temperatures, we developed a technology called 'electromagnetic vortex'. This technology was inspired by observing and studying the 'solar prominences' on the sun, combined with 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 controllable temperature is 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 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 about 5 meters. Its interior can even be heated through magnetic fields 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. In other words, using 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¡¯s talk about the three plasma engines currently being studied.
The first one 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. These two ions will form a double helix cyclone inside hydrogen and outside oxygen in the environment of electromagnetic field.
And 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 finally exits from the rear of the engine.;The planet has a large target, poor defense, is easy to be attacked, and has a loose structure that can easily disintegrate. Even if you want to install the 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, thereby triggering a global disaster.
¡°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 Dayang 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 a relatively perfect spherical shape after a long enough time. But in fact, this trend will occur when the object exceeds 400 kilometers in diameter.
Once the volume is too large, the spacecraft will collapse itself after being damaged.
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." (Remember the website address: www.hlnovel.com
