Looking at Cheng Feng, who was in a somewhat crazy state in front of him, and some other experts who didn't know him, Zhang Jingyuan took his real team into the broad real center.

Next to it, Zhang Jingyuan and others have completed three pairs of 30 cm diameter wireless energy transmission devices, undergoing destructive experiments, although this kind of test is very expensive and destructive, but the effect is also top-notch, basically there are no flaws to hide.

A group of experts came around, and Wang Qingwei, the direct person in charge of the project, was even more excited to start preparing for the real thing.

"1.5V voltage, start ...... 3V…… 36V……”

"The current is always 1A, and the number of records is ......"

"The voltage is 380V, 1A, and the conversion efficiency is 83% at a distance of 1 meter. Okay, the next step, increase the current ......"

"At 380V, the current starts to rise, 2A...... 10A…… 20A…… Thorn !! ”

In an instant, something happened that no one expected, and it was also a change that had not occurred since the test - burned!

This...... All the experts looked at each other, but Wang Qingwei quickly opened the electric switch and began to carefully check. Anyway, ninety and a half percent of the metal can be recycled.

On the side, Cheng Feng was suddenly a little disappointed, although he knew that the experiment could not be successful at one time, and every time it was an adventure, but if it really failed, he would still be a little disappointed.

Fortunately, at least the early low-pressure test has been successful, and maybe the high-pressure test will be soon.

"The current is too high, and the internal superconducting coil burns out." Wang Qingwei gave an explanation that experts could not accept!

Boy, are you sure you're right? The superconducting coil is burned out!! Since it is a superconducting material, there is no resistance at all, how can it burn out? If there is no resistance, there is no heat generation, and if no heat is generated, how to burn out!!

"Cheng Lao, don't worry, listen to my explanation." Wang Qingwei is also an expert now, especially in this research; Coupled with Zhang Jingyuan's intentional or unintentional cultivation of the talents of his brothers, Wang Qingwei and others have grown up very fast. For example, today, Li Changxing alone can support the present and future research and development of chips.

"Cheng Lao, superconducting materials are like highways, and they are super highways, but highways also have a carrying ceiling.

According to some of the numbers and analyses we obtained, the current, like the flow of water, also has an alternative pressure, but this pressure is not visible in the general wire, because the current in the general wire is really limited.

But when this current reaches a certain limit, there will be a pressure similar to pressure on the material, and once the material can no longer withstand this pressure, the characteristic of the table is burning. It was caused by the high temperature generated by the instantaneous burst of electric current. ”

"Very good, very good, young man, we also found this problem in the real yàn, but we didn't expect to be broken by you, now that I think about it, it's really the case." An expert in electrical engineering.

"That's it......" Cheng Feng was a little depressed, and the problem occurred in the material. It's just that in today's era of science and technology, there are many restrictions on the development of science and technology, but materials are undoubtedly the most important problems.

"Cheng Lao, how about we experiment with this material that I accidentally obtained?" Zhang Jingyuan reminded, don't continue to be disappointed, what you have in your hand can solve the new materials of plasma engines. This kind of material developed with the support of spiritual civilization mainly uses electricity, carbon and platinum elements to form a material that is not yet unimaginable in this world - low-temperature complete thermal insulation material! The low temperature mentioned here is the low temperature in the cultivation, and the various true fires on the refining device are expressed by the current temperature, which is the temperature of tens of thousands at every turn, and the so-called low temperature refers to the temperature below 10,000 degrees.

This kind of material, which often appears in cultivation, especially in the process of refining, is considered an impurity, but I did not expect that there will be other top-notch applications here. Sure enough, there is no garbage, only misplaced resources!

This material is also a memory that Zhang Jingyuan inadvertently turned out. Of course, since it is a material for cultivating civilization, even if it is a garbage scrap, it is not an ordinary thing.

"Okay, I'll see!" Cheng Feng handed over the materials to another expert, who was an expert in materials. "Lao Wang, this is said to be a material that Xiao Zhang accidentally discovered, it looks good, let's make a real one."

This person's name is Wang Jincai, and he is an old expert who is almost sixty years old, leading the research and siege of the Flying Dragon fighter materials. He is also one of the top material experts in China, of course, an expert in aviation materials. Today's aviation materials are titanium alloys, followed by aluminum alloys and carbon fiber materials, and finally new types of steel.

"Oh? I'll take a look at ......" Wang Jincai took over this nail-sized material, and when he came into contact with the material all year round, he could roughly guess the preliminary physical properties of this material at room temperature at first glance.

"Very light, the density is estimated to be close to 1 (the density of water)," and then, with this material, scratched the titanium alloy material in his hand, "The hardness is good, at least 60 hardness (the hardness of kitchen knives at home is generally between 45-55HRC), and the specific hardness needs to be measured."

Well? This material turned out to be insulated!! Wang Jincai soon discovered the surprise, in such a hot day, a small piece of material can not feel any temperature, there is only one possibility - adiabatic! And it's real adiabatic.

The discovery of this problem was enough to arouse Wang Jincai's strong interest. "It's possible that it really is an amazing material that was discovered by accident! How many inventions are unintentional by-products!! ”

Watching the experts run to the material room, Zhang Jingyuan smiled and believed that this material would definitely be able to meet the needs of the Flying Dragon fighter. As the saying goes, the rise and fall of the country is the responsibility of the husband, and with a good country as the back, you can develop with peace of mind. Whether it is for oneself, the country or the nation, it is a good choice.

"Testing conductivity...... Almost completely insulated! ”

"Testing Heat Transfer Performance...... Completely adiabatic !! Completely adiabatic! It doesn't conduct heat at all! It is estimated that it cannot melt at normal temperatures! ”

"Test hardness...... Test tensile strength ...... Test the elastic strength ...... Test Vibration Test ......"

Perfect!!!

After a simple preliminary test, under the existing aircraft parameters, this piece of material is basically intact, and its excellent performance directly conquered all the people on site.

"Xiao Zhang, how much is this material worth? Can it be produced on a large scale? At this moment, not only Wang Jincai was red-eyed, but even the power system engineers next to him were red-eyed. Such a material, if the price is right, whether it is to make the shell of an aircraft or the engine or even something else, is a top-notch material. The density is only 1, which is lighter than aluminum alloy, and the important thing is that the strength is enough! On the other hand, because it is a thermal insulation material, it can better improve the engine power and reduce the outer layer of the cable.

At least 70% lighter aircraft with the same performance! An expert estimates on the side! And this 70% of the weight can be completely moved to the battery, which has an incalculable impact on the performance of the aircraft.
