Looking at the slightly crazy Cheng Feng and other experts he knew and didn't know, Zhang Jingyuan led his experimental team into the spacious experimental center.
Next to it, three pairs of 30 cm diameter wireless energy transmission devices that Zhang Jingyuan and others have completed are undergoing destructive tests. Although this kind of test is very expensive and very destructive, the effect is also top-notch, and there are basically no flaws. Able to hide.
A group of experts gathered around, and Wang Qingwei, the direct person in charge of the project, danced excitedly and started preparing for the experiment.
"1.5v voltage, start...3v...36v..."
"The current is always maintained at 1a, and the data is recorded..."
"Voltage 380v, 1a, 1 meter distance conversion efficiency 83%. OK, next step, increase the current..."
"At 380v, the current begins to increase, 2a... 10a... 20a... sting!!!"
In an instant, something unexpected happened, something that had not happened since the experiment - it burned!
This... all the experts looked at each other, but Wang Qingwei quickly opened the switch and began to check carefully. Anyway, 95% of the metals here can be recycled.
Next to him, Cheng Feng suddenly felt a little disappointed. Although everyone knew that the experiment could not be successful every time, and every time it was a risk, he would still be a little disappointed if it really failed.
Fortunately, at least the early low-voltage test has been successful, and maybe the high-voltage test will be soon.
"The current is too large and the internal superconducting coil is burned out." Wang Qingwei gave an explanation that experts cannot 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, so how can it burn out? Without resistance, there is no heat generated. If no heat is generated, how can it burn out? ! !
"Mr. Cheng, don't worry, just listen to my explanation." Wang Qingwei is now considered an expert, especially in this field of research. In addition, Zhang Jingyuan intentionally or unintentionally cultivates the talents of his brothers, Wang Qingwei and others have grown up Very fast too. For example, today, Li Changxing alone can support the current and future research and development of chips.
"Mr. Cheng, superconducting materials are like highways, and they are super highways, but highways also have a load limit.
According to some data and analysis we have obtained, current, like water flow, also has a different kind of pressure, but this pressure cannot be seen in ordinary wires because the current in ordinary wires is really limited.
But when this current reaches a certain limit, it will exert a pressure similar to pressure on the material. Once the material cannot withstand this pressure, the characteristic it exhibits is burning. That is caused by the high temperature generated by the instantaneous burst of electric current. ”
"Very good, young man, we also discovered this problem in the experiment, but we didn't expect you to reveal the secret. Now that I think about it, it is really the case." An expert in electricity.
"That's it..." Cheng Feng was a little depressed. The problem was with the materials. It's just that in today's technological era, there are many constraints on the development of science and technology, but materials are undoubtedly the most important problem.
"Mr. Cheng, how about we test this material that I accidentally obtained?" Zhang Jingyuan reminded, don't continue to be disappointed. What you are holding in your hand is a new material that can solve the problem of plasma engines. This kind of material developed with the support of spiritual civilization mainly uses electric energy, carbon elements and platinum elements to form a material that is unimaginable in this world - low-temperature completely insulating material! The low temperature mentioned here refers to the low temperature in practice. The various real fires on the refining tools, expressed in current temperatures, can easily reach temperatures of tens of thousands. The so-called low temperature refers to temperatures below 10,000 degrees.
This kind of material often appears in practice, especially in the process of refining weapons. It is regarded as an impurity, but I did not expect that it would have other top applications here. Sure enough, there is no garbage, only misplaced resources!
This material is also a memory that Zhang Jingyuan accidentally dug up. Of course, since it is the material of cultivation civilization, even if it is garbage leftovers, it is not ordinary stuff.
"Okay, let me take a look!" Cheng Feng handed the materials to another expert, an expert in materials. "Old Wang, this material is said to be discovered by Xiao Zhang accidentally. It looks good. Let's do an experiment."
This man's name is Wang Jincai. He is an old expert who is almost sixty years old. He leads the research on Feilong fighter materials and sieges the city. He is also one of the top materials experts in the country, and of course an expert in aviation materials. Today's aviation materials are primarily titanium alloys, followed by aluminum alloys and carbon fiber materials, and finally new steel materials.
"Oh? Let's take a look..." Wang Jincai took the fingernail-sized material. He has been exposed to materials all year round, and he can roughly guess the preliminary physical properties of this material at room temperature at first glance.
"It's very light. The density is estimated to be close to 1 (the density of water)." Then, he scratched the titanium alloy material in his hand with this material. "The hardness is good, at least 60 hardness (the hardness of kitchen knives at home is generally between 45-55hrc). ), the specific hardness needs to be measured
Um? This material is actually insulating! ! ! "Wang Jincai soon discovered a surprise. On such a hot day, a small piece of material can't feel any temperature. There is only one possibility - insulation! And it is real insulation.
The discovery of this problem was enough to arouse Wang Jincai's strong interest. "It's possible that an amazing material was discovered accidentally! How many inventions are unintentional by-products!!!"
Seeing the experts rushing to the materials laboratory, Zhang Jingyuan smiled and believed that this material could definitely meet the needs of the Feilong fighter. As the saying goes, everyone is responsible for the rise and fall of a country. With a good country as its backing, one can develop with peace of mind, right? It is a good choice for yourself, the country and the nation.
"Testing electrical conductivity...nearly complete insulation!"
"Testing heat transfer performance...completely adiabatic!!! Completely adiabatic! No heat conduction at all! It is estimated that it cannot melt at normal temperatures!"
"Test hardness...Test tensile strength...Test elastic strength...Test vibration test..."
Perfect! ! !
After a simple preliminary test, under the existing aircraft parameter data, this piece of material was basically intact, and its excellent performance directly conquered everyone 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 jealous, but even the power system engineers next to him were jealous. Such materials, if the price is right, are top-notch materials whether they are used for aircraft casings, engines, or anything else. The density is only 1, which is lighter than aluminum alloy. The important thing is that it is strong enough! On the other hand, because it is an insulating material, it can better improve the engine power and reduce the outer layer of the cable.
At least it can reduce the weight of the aircraft by 70% with the same performance! An expert is on hand to estimate! And this 70% of the weight can be moved to the battery, which has an immeasurable impact on the performance of the aircraft.
