Zhou Yu agreed to the request of Song Guangshun, deputy chief designer of Chengfei, and immediately began to lead the Science and Technology Committee to plan the experimental direction of absorbing materials.

The main person in charge was Feng Yunde, who began to mobilize researchers from the Institute of Materials Research to conduct experiments.

In a laboratory of the Materials Research Institute, Feng Yunde said confidently: "We must grasp the essence of the matter and repeatedly explore why metal crystal alloys produce this phenomenon."

Only by finding the specific principle of the occurrence of this phenomenon, we can theoretically deduce the required substance, then it will be very easy. ”

Feng Yunde immediately followed the experimental path he designed and began to develop absorbing materials that met Song Guangshun's standards.

The first thing they had to do was find out what kind of structure silver iodide crystals and niobium metal crystals formed when they were mixed to convert visible light into high-voltage electricity.

Time passed slowly, and Feng Yunde led the researchers to keep trying.

They crushed silver iodide crystals and niobium metal crystals through equipment, and the formed nanopowder was heated and melted in a reaction furnace to form a material that can absorb visible light.

They repeated this process over and over again, using an electron microscope to observe the internal structure of the material after it had been formed.

And constantly adjust the specific parameters of the formation of alloy materials, through the method of continuous comparison, to find the specific reason why this alloy can absorb visible light.

Feng Yunde's face was a little anxious, after thousands of comparative experiments, he did not find out which factor played an important role in the absorption of visible light by the alloy material.

Researcher Wei Fanghai suggested: "Director Feng, is it a problem with our reactor, maybe the impurities in the reactor are involved in the material."

Feng Yunde's eyes lit up, he really didn't expect this, and it was also one of the possibilities.

After the laboratory replaced the reactor, the alloy material was quickly manufactured, and he was surprised by the test results.

Feng Yunde said in shock: "Sure enough, it is related to this reactor, after we replace the reactor, the alloy material no longer has the ability to absorb visible light and convert it into high-voltage electricity."

He immediately asked the researchers to begin looking for similarities and differences between the two reactors and to conduct detailed investigations.

After a thorough inspection of the laboratory equipment, they found that the specific cause was that the reactor they had been using was probably due to excessive pressure in one of the reactors.

A gap of about 10 microns leaks out of the furnace lid, allowing airborne impurities to enter the alloy.

Feng Yunde immediately grasped the key point and conducted research in this direction.

In the end, he found that the range of light wave absorption of this alloy was actually related to the structure of nitrogen dioxide molecules inside the alloy and the formation of alloy crystals.

If you find the specific reason, you can easily summarize the law according to the big data, and deduce the comprehensive absorption of electromagnetic waves and the specific structure inside the alloy.

Feng Yunde immediately sent the news to Zhou Yu to share this good result.

Zhou Yu received Feng Yunde's news, and he immediately said happily: "Dadezi, your research and development speed is really fast, it has only been a month, and you have solved the problems encountered by Song Guangshun and them."

Feng Yunde said modestly at all: "This is my ability, figuring out this not too important material, if it takes a lot of time, how can it show my ability."

Zhou Yu immediately called Song Guangshun to inform him that the absorbing material he needed had been developed.

"Song Guangshun is really in a hurry, he will take a plane to come over immediately, and he estimates that he will be there in the afternoon." Zhou Yu said with a smile.

"Mr. Zhou, look at how advanced the absorbing materials we are researching."

As Feng Yunde spoke, he showed the alloy data he had studied to Zhou Yu.

After Zhou Yu checked the data, his expression was very flat at first, and after carefully looking at the data, he showed a look of surprise.

"Dadezi, your research and development of this material is very promising, its photoelectric conversion ratio is very high, this is a very excellent solar panel material." Zhou Yu said happily.

Feng Yunde carefully recalled the specific physical properties of the alloy, and he said excitedly: "How did I not think that in addition to the ability to absorb electromagnetic waves, it can also convert electromagnetic wave energy into electrical energy.

With an energy conversion ratio of up to 90%, this is really a highly efficient material for solar panels. ”

"It is estimated that solar electric vehicles should have commercial value in the future, and solar power stations also have real practical value." Zhou Yu said with emotion.

Of course, solar panels with high efficiency energy conversion ratios are not only used for this purpose, they also have a very rich use.

"I just wanted to solve Song Guangshun's problem, but I didn't expect to find such a big market, he is really my lucky star." Feng Yunde said happily.

Zhou Yu and Feng Yunde chatted about the application of solar panels, and the more they chatted, the happier they became, and they discovered a technology that was very important to Xinghuo Technology.

Feng Yunde also showed a very proud look between the lines, he was finally not afraid of being surpassed by latecomers, other scientists were very crazy, and he was more salty.

Song Guangshun soon came to Xinghuo Technology, and Zhou Yu led him to the testing laboratory.

On the way, Song Guangshun still said in disbelief: "It succeeded so quickly, and the research and development speed of your Spark Technology is too fast."

I found three units to develop this project, and the others have not yet discussed the specific scientific research path, and you actually made the finished product. ”

Song Guangshun came to the laboratory, and he saw a lilac material with a metallic luster on the laboratory table.

Next to this piece of material is a high-pressure cylinder.

Feng Yunde introduced: "This is the absorbing material, which is a metal alloy that has been debugged into micron-sized metal alloy particles.

With the reagents we have developed, they can be sprayed on any metal by spraying.

Your craft should have been in project for a long time, and perhaps the shell has already been designed and manufactured.

Our absorbers are coated in a way that does not affect the aerodynamic shape of the aircraft housing.

It must be sprayed on the conductor because the absorption of electromagnetic waves converts the energy of the electromagnetic waves into high-voltage electricity.

The stored electrical energy must be exported through an effective way, otherwise it is likely to cause a discharge phenomenon like a lightning strike. ”

Song Guangshun listened to Feng Yunde's narration, he kept nodding his head, and said happily: "Your material is very good, and it is very thoughtful, can I see its specific effect?"

Feng Yunde immediately instructed the scientific research assistant to conduct experiments, and at the same time introduced Song Guangshun: "Our laboratory does not have real radar, but our laboratory equipment can simulate the electromagnetic waves of radar signals.

We can guarantee that the absorber absorbs 100% of the electromagnetic waves on the irradiated material.

Unless the radar department uses electromagnetic wave detection, it will definitely not be able to detect aircraft using this material. ”

Song Guangshun soon got the experimental results, and he found that this absorbing material can really absorb 100% electromagnetic waves.

He choked up and said, "The last hurdle was solved, and our project was finally successful."

Zhou Yu patted Song Guangshun's back and solemnly reminded: "Designer Song, don't be too excited, this kind of absorbing material also has great drawbacks.

At present, electromagnetic waves are used in the means of communication, and once the aircraft applies this absorbing material, it will not be able to receive communication from the outside world. ”

Song Guangshun was stunned for a moment, and then said with a smile: "This matter is easy to solve, just like a nuclear submarine that has been active on the bottom of the sea for a long time, and can only use buoys to receive information from the outside world regularly."

Our fighters can also use buoy-like settings, and when the fighters really attack, they are already in combat state, and there is no need for additional orders. ”

Song Guangshun was constantly grateful to Zhou Yu and Feng Yunde, and when he left, he took 300 kilograms of absorbing materials and went back to do experiments on fighter jets.
