Hand rubbing nuclear fusion live in the wilderness

Chapter 248 The shadow exceeds the speed of light?
In just 10 minutes, the high-strength and corrosion-resistant Portland cement was melted into a glass-like substance by the high-temperature ion plume.

This terrifying performance stunned the audience in the live broadcast room.

When the engine was running before, although everyone saw the damage to the concrete wall, it was relatively far away at that time, and the electric propulsion engine was running, and the plume of the tail would interfere with the picture to a certain extent, so it was not very clear. .

And this will be near, and the complete details of the damage will be revealed to everyone. Most of the audience did not expect that the surface of the Portland cement wall would melt away directly.

You must know that when the concrete wall was built before, the anchor clearly stated that the Portland cement he used was different from the cement used to build houses.

This Portland cement has an aluminate material skeleton added, which is far superior to ordinary Portland cement in terms of high temperature resistance.

Ordinary Portland cement will start to soften at about [-] degrees and melt at about [-] degrees.

Then this kind of cement with aluminate skeleton can resist the high temperature of [-] degrees.

They didn't believe it at the time, but later Han Yuan personally tested it and showed it to them.

In the laboratory, the temperature was continuously raised to about 10 degrees with an acetylene spray gun for nearly [-] minutes before the cement began to melt and become a flowable liquid.

But looking at it now, on the front concrete wall, an area with a radius of about one meter has been melted. Only then did the audience realize the horror of the ion plume.

[Holy shit, melted? 】

【I remember that this kind of cement has been able to resist the high temperature of 2300 degrees, right?At that time, the anchor was still using an acetylene spray gun to heat it up until it barely melted. 】

[What a terrifying temperature! 】

[It should be said that the impact speed is fast ()]

【Visual inspection shows that the distance between the concrete wall and the engine tail is at least ten meters. It has melted. How high should the engine exhaust flame be? 】

[Air ions are not scary, what is scary should be the speed at which they are thrown out, don’t even think about it, they can provide such a terrifying thrust, how fast these air ions are when they are thrown out of the engine! 】

【Super speed of light! 】

[In theory, now you can see Qin Shihuang as long as you catch up with the light emitted by the earth more than 2200 years ago. 】

[Things that exceed the speed of light do not exist. For example, the expansion of the universe, such as shadows, are all faster than the speed of light. 】

[I admit that the expansion of the universe exceeds the speed of light, and the shadow exceeds the speed of light?Nonsense! 】

[But the shadow can indeed exceed the speed of light, Einstein proved it with thought experiments and formulas. 】

[Super ass!The foundation of shadow existence is established on light, can it exceed the speed of light? 】

[Einstein: When will I prove this? ? ? ? 】

[Super-light speed is very easy, and everyone can easily do it. You just need to turn around in place. According to the theory that motion is relative, assuming you are stationary, the entire universe will revolve around you in an instant. Not only faster than the speed of light, but also super-divine speed. 】

[I am stupid. . (⊙_⊙)]

Just after checking the damaged concrete wall, when he turned his head, Han Yuan saw that there was another noise in the live broadcast room.

But this time the noise is more 'scientific'?
This group of people is discussing whether the shadow can exceed the speed of light.

For this question, Han Yuan can only say that he does not know the answer.

Because there is no relevant content in the knowledge information obtained so far and the knowledge information he has learned.

As for the things he learned in human society before getting the system, to be honest, he basically returned them to the teacher.

He fell asleep most of the time in the Big Object class.

There is no way, the teachers in the big things class seem to be better at hypnosis.

Han Yuan has always thought that if one day his teacher of big things is not a teacher, it would be good to become a hypnotist.

So now he simply ignored the barrage of arguments and began to check the electric propulsion engine.

Anyway, this group of people can't come out with any results from their quarrel, at most they just make themselves and others 'explode' with anger.

In the test site, the electric propulsion engine is firmly fixed on the steel frame, so that it does not produce any displacement during operation.

The thrust of more than 150 kN is nothing to use chrome-iron alloy with a thick calf.

What's more, the bottoms of these chrome-iron alloy steel frames are welded together and buried deep in the soil, and covered with Portland cement half a meter deep.

And the cement floor of the whole test site is connected to each other.

Let alone a thrust of 150 kN, even a force of [-] kN may not necessarily make it move.

The first inspection, of course, is to use an enhanced light flashlight with naked eyes to judge whether there are cracks, damage, or leaks in the engine casing, and whether the bolts and rivets used for fixing are deformed or popped out.

With the remaining hot residual heat, Han Yuan carefully checked the titanium alloy metal plates of the engine casing.

Every bolt and rivet was not spared, including whether there were any bulges on the titanium alloy skin, and Won paid careful attention to it.

But after going through the inspection process again and again, no problems were found.

However, the internal situation is still uncertain, and the engine will need to be towed back to the factory to be disassembled for inspection.

At least on the surface, it looks quite intact, which still gives Han Yuan a lot of confidence.

After waiting for the engine to cool down, he disassembled the fixing part, and then used the hanging rail device to transport the huge engine back to the steel bar workshop.

The outer alloy plate armor was disassembled by Han Yuan, and the situation inside was checked step by step.

Visual inspection, hole detection, supersonic, bottom crack, multimeter to measure current, voltage and resistance, insulation meter to measure insulation, NDT detection, data physical and chemical analysis.

A series of process inspections took the Korean won two full days.

Of course, this is the first factory inspection, so it is natural to go into more detail.

When the last test was completed, looking at the test data in his hand, Han Yuan nodded with satisfaction, and then reassembled the disassembled engine.

While assembling, Han Yuan smiled and said, "Judging from a series of test results, there is absolutely no problem with this electric propulsion engine."

"It's just the limit test and the inspection after the limit test."

"If I can pass it, I can start the next step."

[Ah, ah, ah, it will definitely pass. 】

【What's the next step? 】

[The next step should be to manufacture the skeleton of the aircraft, right? 】

[When will I be able to fly into the sky! 】

[What is the next step? Of course, the next step is to rub the lithography machine by hand and upgrade the computer chip! 】

[Be more courageous, the female ghost is on maternity leave, the next step is to rub the spaceship with your hands! 】

Regarding the next step that Han Yuan said, ordinary viewers in the live broadcast room began to speculate, and even experts and scientists from various countries and even high-level officials were very interested.

Because at present, even if the electric propulsion engine is built, it is obviously not a finished product.

Moreover, the follow-up engine control program, power supply, and the overall structure of the aircraft have not yet been done.

And these are things they are very interested in.

Especially the power supply.

All countries concerned about the live broadcast room are speculating on how the South Korean won will provide power to the electric propulsion engine.

Obviously, the power consumed by an electric propulsion engine alone is not a small amount.

What's more, according to the design on the drawings, there are a total of six electric propulsion-free fluid engines on an aircraft.

How to provide such a huge power consumption is what they are most interested in.
