Li Fu, Liu Shiying and others looked at the silver-gray engine in front of them as if they were looking at a rare treasure, about 5 meters long and 1 meter in diameter.

"Haha, I didn't expect that we could make a plasma engine in just over 1 month, if it weren't for Xiao Li, I really couldn't think of it, we thought it would be quite good if we could make progress in ten years, but now it's just over 1 month."

Liu Shiying couldn't help but sigh for a while, after more than 1 month of getting along with Li Fu, he really understood how terrible the genius Liu Yi said, there is nothing that Li Fu doesn't understand, many people can't think of a way to break their heads, Li Fu can come up with it one by one, and the speed of the entire project can be described as traveling thousands of miles a day.

"Lao Liu, you have won the award, if you don't work together and don't have the strong support of the country in the back, even if I have some ideas, it will be completely useless, not to mention that if it weren't for everyone's experience in designing aero engines in advance, we would definitely not be able to complete it overnight if we really started from scratch."

Li Fu smiled and shook his head, although Li Fu is now at the core of plasma engine research, but this kind of thing is naturally to be modest, and now he is quite harmonious with Liu Shiying's team, and even calls Liu Shiying Lao Liu.

"Haha, let's not be busy with joy first, let's hurry up to the wind tunnel test, only if the test is successful, can it be regarded as a real success, and I don't know if our use of new materials and the most advanced air cooling technology can withstand the high temperature of the engine core."

Liu Shiying saw Li Fu's modest appearance, nodded with satisfaction, and quickly turned the topic back to the plasma engine, and was still faintly worried in his heart, because according to theoretical inference, the working temperature of the plasma engine is above 2000 degrees, and the core temperature can reach 5000 degrees.

Soon after, the engine was transported to the wind tunnel for the most critical tests.

Through the thick glass, Li Fu, Liu Shiying and others looked at the plasma engine quietly waiting for the test, everyone seemed a little excited, after all, this is the first plasma engine in China, although it is not yet known how the performance is, but everyone is still excited.

"Let's go!"

With Liu Shiying's order, someone next to him gently pressed a few openings, and everyone's eyes were staring at the engine in the wind tunnel laboratory.

Li Fu only felt that the entire ground trembled slightly, in the laboratory, the plasma engine started instantly, and the powerful air compression ability could instantly evacuate all the air in a space the size of a basketball hall, even if it was separated by thick glass, Li Fu still heard a thunderous roar.

I saw an orange-red tail flame shoot out from the tail of the engine, the length of which reached dozens of meters, and then soon the orange-red tail flame turned into a completely blazing tail flame, which was very dazzling, as if looking at the sun with only one eye.

As the orange-red tail flame completely turned into a blazing white tail flame, the temperature in the surrounding air rose rapidly, and there was a faint sense of haze, and a strong heat seemed to be coming, even through the thick glass, there was still heat conduction.

"Didi!" "Didi! There was a huge monitor next to everyone, and all kinds of data were changing rapidly, making the people in the research group smile.

The engine's thermal efficiency, propulsion efficiency, total efficiency, EPR (engine pressure ratio), N1 (fan speed), EGT (exhaust temperature), power consumption and other data are constantly beating on the huge display.

"Great, this is just the beginning and has surpassed the most advanced engine parameters in the world, if the power meter is fully open, it is absolutely terrifying."

"No wonder it is said that the plasma engine is the core of the future fighter, and it is the existence of the so-called aerospace fighter, this data is too perfect!"

"I can't imagine that we can also make such an advanced engine, this power, this temperature, leverage!"

The researchers in the research group looked at the numbers on the huge monitor, and all of them had smiles on their faces, and they knew too well what the data meant.

"It's really an electric tiger, look at the consumption of this electricity, it has consumed more than 5,000 kilowatt-hours of electricity in less than a few minutes!"

"This thrust is so powerful that our entire wind tunnel laboratory faintly feels that it is trembling, and we see that there is no water cup on the table, our wind tunnel is the highest standard wind tunnel laboratory!"

"The temperature of this outlet is too high, it has exceeded more than 2,000 degrees, and the temperature of the core of this rotor must be doubled, and I don't know if our new materials and the most advanced air cooling technology can meet it, otherwise, this rotor will not last long."

As if to verify this sentence, the engine that was originally spewing a blazing white tail flame suddenly appeared on its tail, and the whole engine began to turn red, and then soon began to turn white, like a red-hot piece of steel, so that everyone immediately realized that something was wrong.

"Oh no, stop the engine immediately!"

Liu Shiying shouted loudly, and the person next to him immediately pressed a few buttons to stop transmitting high-voltage electricity to the engine.

"Coax!"

As the roar gradually became smaller, the engine slowly stopped, but the black gas was still coming out, and then you could see the open flame burning from the engine.

However, this wind tunnel laboratory is the most advanced laboratory, and soon, water droplets in the wind tunnel laboratory sprayed into the engine, countless water mist covered the entire wind tunnel laboratory, and then the powerful exhaust system in the wind tunnel laboratory quickly exhausted all the water vapor and so on.

After a long time, a completely scrapped engine appeared in everyone's field of vision, the shape of the engine has been slightly deformed at this time, as if the magma has been dried, there are obvious traces, the rotor of the core of the engine has completely melted away at this time, turned into molten iron flowing out, and after cooling, it became dry candle oil.

"More than a billion is gone!"

Someone next to him looked at this engine, the whole population was dumbfounded, all the materials used in this engine are the most advanced materials in Huaxia at present, plus the processing and manufacturing of various blades, etc., the cost of the entire engine alone cost more than one billion Chinese dollars.

Liu Shiying on the side had a black face, his face was very ugly, and he looked stunned when he looked at the engine that was gradually cooling down.

"Materials, or materials!"

Li Fu's brain did not carry the analysis, and soon came to the conclusion that it is not that the plasma engine is not good, but that the materials used to make the plasma engine are not good, relying on a strong current to ionize compressed air, the temperature is as high as 2000 degrees, and the core temperature is as high as 5000 degrees, even if the most advanced air cooling technology and the most advanced high-tech materials are used.

However, in less than ten minutes, the rotor of the entire engine core was completely burned out, melted into molten iron, and the entire engine was completely scrapped.

"Why is this happening, we have clearly researched the plasma engine, but in the end we still lost to the material level!"

Liu Shiying looked a little frustrated, this engine has used the most advanced materials in Huaxia, the most advanced air cooling technology, but it still can't withstand the high temperature of the core.

"Lao Liu, don't be discouraged, problems always appear one by one, just like before, we haven't encountered many problems, we just solve them one by one."

"Judging from the experiment just now, at least we have developed a plasma engine, at least it has shown that our efforts are not completely fruitless, and there are fewer and fewer problems to be solved later, as long as we can find high-temperature materials that can withstand this temperature, we can be regarded as a real success."

Li Fu looked at Liu Shiying's depressed expression and couldn't help but go over to comfort him.

"It's difficult, the temperature of the core of this engine is more than 5000 degrees, we use the materials in aerospace science and technology and the most advanced air cooling technology, but there is still no way, look at this engine, the rotor of the core is all melted, it is only less than ten minutes."

Liu Shiying shook his head helplessly, the failure of this test was undoubtedly due to the material, and everyone present was very clear about this.

Material science and technology, don't look inconspicuous, it doesn't sound lofty, but often material science and technology is the basis that determines the height of a country's science and technology, and many of the country's scientific research projects have always had a big gap with the international advanced level, a large part of which is the material reason.

To take a very simple example, the materials used for the core rotor of the aero engine must have high temperature resistance, friction resistance, and continue to work at high temperatures without deformation, and many other demanding and strict requirements, which cannot be met by ordinary materials.

And our country for the basic materials, the previous attention is not enough, so the development of material science and technology is relatively different from the world's advanced countries, material science and technology is not much high, the real need is to continue to spend a lot of data to experiment.

Only with a large enough experimental data can we say that there are achievements in material science and technology, but this kind of continuous investment in resources to experiment, but the results may not be able to quickly bear fruit in the project, our country did not attach much importance to this in this regard, only in the last ten years, the more to the development of high-end science and technology, the more gradually realized that basic material technology has become a big obstacle, this vigorously invested resources into it.
