Universe dominance

Li Fu, Liu Shiying and others looked at the silver-gray engine in front of them as if they were looking at rare treasures. It was about 5 meters long and 1 meter in diameter. It was full of streamlines and faintly glowing, like a product from a science fiction movie. generally.

"Haha, I didn't expect that we could actually create a plasma engine in just over a month. If it weren't for you, Xiao Li, it would have been something we wouldn't have dared to think about. At the beginning, we thought that if we could make some progress within ten years Even though it’s pretty good, it’s only been over a month now.”

Liu Shiying couldn't help but sigh. After spending more than a month with Li Fu, he truly understood how terrible Liu Yi said genius was. There was nothing that Li Fu didn't understand. Many people thought Li Fu could come up with methods that he couldn't even think of, one after another. The entire project progressed at a speed that can be said to be a thousand miles a day.

"Old Liu, thank you for your praise. Without everyone's concerted efforts and the strong support from the country, even some ideas I have will be of no use at all. What's more, without everyone's experience in designing aeroengines, we would really If you start from scratch, you will definitely not be able to complete it overnight.”

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

"Haha, let's not be too busy to be happy. Let's quickly conduct a wind tunnel test. Only when the test is successful can it be considered a real success. We don't know if our use of new materials and the most advanced air-cooling technology can withstand the core of the engine. high temperature.”

Seeing Li Fu's humble look, Liu Shiying nodded with satisfaction, and quickly turned the topic back to the plasma engine. She was still worried, because according to theoretical inference, the operating temperature of the plasma engine is above 2000 degrees, and the core The temperature can reach 5,000 degrees. Such a terrifying high temperature is definitely the biggest test.

Soon, the engine was transported to the wind tunnel experiment, ready to undergo the most critical wind tunnel experiment test.

Through the thick glass, Li Fu, Liu Shiying and others looked at the plasma engine that was quietly waiting for testing. Everyone seemed a little excited. After all, this is the first plasma engine in China, although it is not yet known what its performance is. Like this, but everyone was still excited.

"start!"

Following Liu Shiying's order, someone next to him gently pressed several openings, and everyone's eyes were fixed on the engine in the wind tunnel laboratory.

Li Fu only felt that the whole ground was shaking slightly. In the laboratory, the plasma engine started instantly. The powerful air compression ability was able to evacuate all the air in a space the size of a basketball gym in an instant. Even if it was separated by thick glass, Li Fu Fu still heard the thunderous roar.

I saw an orange-red tail flame jetting out from the rear of the engine, with a length of several tens of meters. Soon the orange-red tail flame turned into a completely blazing white tail flame, which was very dazzling, as if it was a Look at the sun with your eyes.

As the orange-red tail flame completely turned into a blazing white tail flame, the temperature in the surrounding air increased rapidly, and there was a vague sense of hazyness. A powerful heat seemed to be coming towards you, even though there was a thick layer of The glass still conducts heat.

"Didi!", "Didi!" There was a huge monitor next to everyone. Various data were changing rapidly, making the people in the research team 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.

"It's great. This has just begun and it has already surpassed the most advanced engine parameters in the world. If the power meter is fully opened, it will be 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 so perfect!"

"I can't imagine that we can actually create such an advanced engine. The power and temperature are amazing!"

The researchers in the research team looked at the numbers on the huge display with smiles on their faces. They who study engines know very well what these data mean.

"He is really an electric tiger. Look at the electricity consumption. In just a few minutes, he has consumed more than 5,000 kilowatt-hours of electricity!"

"This thrust is so powerful that our entire wind tunnel laboratory feels faintly shaking. There are no water glasses on the table. Our wind tunnel is a wind tunnel laboratory with the highest standards!"

"The temperature at the outlet is really too high. It has exceeded 2,000 degrees. The temperature of the rotor core will definitely double. I don't know if our new materials and the most advanced air-cooling technology can meet the requirements. Otherwise, If so, this rotor won’t last long.”

As if to verify this statement, the engine that was originally spitting out dazzling white tail flames suddenly had special gas at its tail. The entire engine began to turn red, and then quickly began to turn white, as if burning. The red steel block made everyone immediately realize that something was wrong.

"No, stop the engine immediately!"

Liu Shiying shouted loudly, and the people next to him immediately pressed a few buttons to stop sending high-voltage power to the engine.

"coax!"

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

However, this wind tunnel laboratory is the most advanced laboratory. Soon, water droplets in the wind tunnel laboratory sprayed towards the engine. Countless water mist covered the entire wind tunnel laboratory, and then the wind tunnel laboratory The powerful exhaust system quickly exhausts all water vapor and so on.

After a long time, a completely scrapped engine appeared in everyone's sight. The shape of the engine was slightly deformed at this time. The inside looked like dried magma, with obvious traces. The rotor at the core of the engine was now completely damaged. It melts and turns into molten iron and flows out. After cooling, it turns into dry candle oil.

"More than a billion are gone like this!"

There were people watching this engine, and the entire population was dumbfounded. All the materials used in this engine are the most advanced materials in China. Coupled with the processing and manufacturing of various blades, etc., the cost of manufacturing the entire engine alone is More than one billion Chinese dollars.

Liu Shiying on the side had a dark face and a very ugly face. Looking at the engine that was gradually cooling down, she looked dumb.

"Materials, or materials!"

Li Fu quickly came to the conclusion without any analysis in his mind that it was not that the plasma engine was not good, but that the materials used to make the plasma engine were not good. It relied on powerful current to ionize the compressed air, with a temperature as high as 2000 degrees, and a core temperature as high as 2000 degrees. 5000 degrees, even using the most advanced air cooling technology and the most advanced high-tech materials.

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

"Why is this happening? We have clearly developed the plasma engine, but we still failed in the materials test!"

Liu Shiying looked a little frustrated. This engine has used China's most advanced materials and the most advanced air-cooling technology, but it still cannot withstand the high temperature of the core.

"Lao Liu, don't be discouraged. Problems always appear one after another. Just like before, we also 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 shows that our efforts are not completely fruitless. There will be fewer and fewer problems to be solved later. As long as we can find a solution to If high-temperature materials can withstand this temperature, we can be considered 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 core temperature of this engine exceeds 5,000 degrees. We have used materials from aerospace technology and the most advanced air-cooling technology, but there is still no way. Look at this engine. The core rotors have all melted. This is only ten seconds. Less than minutes.”

Liu Shiying shook his head helplessly. The failure of this test was undoubtedly due to the material. Everyone present knew this.

Materials technology may seem inconspicuous and does not sound high-end, but materials technology is often the basis for determining a country’s technological level. The reason why many of the country’s scientific research projects have always been far behind the international advanced level is , a large part of it is due to materials.

To give a very simple example, the materials used on the core rotor of an aerospace engine must have high temperature resistance, friction resistance, and continue to work at high temperatures without deformation. Common materials simply cannot meet these stringent requirements. .

Our country has not paid enough attention to basic materials in the past. Therefore, the development of materials technology is quite different from that of advanced countries in the world. In fact, the scientific and technological content of materials technology is not very high. What is really needed is continuous development. It takes a lot of data to experiment.

Only with large enough experimental data can we say that we have made achievements in materials science and technology. However, this kind of project that continuously invests resources in experiments, but the results may not be effective quickly, our country did not pay much attention to this aspect in the past. In the past ten years, as we have developed towards high-end technology, we have gradually realized that basic material technology has become a big obstacle, so we have invested heavily in resources.
