Soon, two days passed.

In the afternoon, a large group of workers were busy in the large assembly room of the airship research and development base, cleaning up the wooden planks and other facilities that had been built.

The second-floor platform of the assembly room has been removed, making it look very empty.

Teacher Zhou and Xu Hongwei stood in front of the door together.

Looking at the large flying saucer in the center and the surrounding emptiness, Mr. Zhou turned his head and asked Xu Hongwei, "The second floor has also been demolished, do you need this?" ”

"It had to be torn down to be safe."

Xu Hongwei explained, "It has been said in the technical data that the superimposed force field of the support covers about five meters, but the impact may reach six or seven meters. ”

"I've talked to other people and they all agree that you need to leave at least 10 meters of space."

Teacher Zhou listened and nodded.

While the two were talking, the demolition work had entered the final stage, and some workers came out carrying scattered equipment and parts.

"Almost."

Xu Hongwei walked in after saying a word, beckoned the others and said, "Do another test, and then prepare for the test!" ”

Detection for newly installed magnetic field generating equipment.

The center-placed Airship-2 aircraft does not need to be inspected, because the internal circuitry of the aircraft is always on, and several electric fans are running all the time.

This is also part of the test.

They need to ensure that the newly installed magnetic field generator does not affect the normal operation of the aircraft's internal circuits.

After all the tests were completed, Xu Hongwei commanded the formal testing, and many non-operators went to the door of the assembly room, where they gathered and waited together.

Everyone is very excited and looking forward to it.

The current test is to have the Air Carrier-2 turn on the stealth shield, which can be understood as a strong annihilation force field to a certain extent.

They all knew the form of the strong annihilation force field, but they had only seen it in the report, and they didn't expect to see it in the experimental base at all, and it had become a new stealth technology.

Many people couldn't help but discuss, "Will it form a black ball that absorbs light, as the report said?" ”

"Probably not, right?"

"According to the information, the strength is only more than 3 points, and it will only be a little gloomy ......"

"If you don't look at it, you don't know."

During their discussion, the anti-gravity system of the air-ship-2 was turned on, but the superconducting motor was not turned on, and no upward thrust was formed, and the aircraft remained in place.

After Xu Hongwei determined that the anti-gravity system was turned on, he instructed the operator to turn on the magnetic field generating device.

The eighteen magnetic field generators are turned on in three phases, starting with the lower ten and then the six above.

The two remaining devices above are the last to turn on.

The purpose of this is to ensure safety and prevent the sudden excitation of the strong annihilation force field, which will affect the surrounding magnetic field, electricity, and then affect the operation of the aircraft.

"Ready!"

"Last step, No. 7, No. 8 ......"

“3、2、1――”

"Start!"

With Xu Hongwei's shout, all eighteen magnetic field generators were activated.

In the next moment, the edge space of the airship-2 became a lake, and further inside was a gray film, which made it uncomfortable for the eyes to look closely.

The hull of the Empty Ship-2 was covered in gray film.

Everyone who saw this scene held their breath, even Mr. Zhou, who had met him once, and the feeling of experimentation and application was different.

When looking at the experiment at the anti-gravity center, it feels like it's just an experiment, everything is made, and it doesn't matter if the device inside the field force can be seen or not.

Now inside the gray film is the empty ship-2 aircraft, and the aircraft is completely covered, and there is nothing to see from the outside, which makes people feel very shocked.

"This is the Invisibility Shield?"

"It's so invisible, I just looked at it a few times and I don't want to look at it anymore...... Uncomfortable ......"

"Don't look too much, the shield absorbs light."

"yes, like you're going to suck your eyes in!"

"That's amazing......"

After satisfying their curiosity, a group of technicians returned to their respective jobs, and they were only testing the manufacture of stealth shields, but they still had work to do.

There are technicians who detect the control radar.

It turned out that neither long-wave radar, short-wave radar, nor infrared radar fed back any data, as if there was nothing there.

The principle of radio radar is that the emitted radio waves will turn back when they hit an object, and then they will be detected by the receiver, and the location, distance, and size of the collision object can be located according to the reflected radio waves.

Now that no feedback signal has been detected, the radar naturally thinks that there is nothing.

A lot of people were shocked.

It's a ridiculous thing to think about, you can see a huge object with your eyes, but the radar doesn't detect anything, it's like a person standing in front of you, you can see clearly with your eyes, but you pick up your phone to take pictures, but you don't get anything.

Many people couldn't help but sigh, "It's really an invisible shield!" ”

"You can see it, but you can't detect anything, that is, you can't be locked by radar equipment, so it's safe to fly at low altitude, right?"

"The enemy can't use his eyes to locate and launch missiles, right?"

"I can now imagine how frightened the enemy will be when the Empty Ship-2 opens the stealth shield and appears, and they may think that aliens are coming......"

"Or do you think what you're seeing is a hallucination?"

"Are you stupid when everyone else? You can also tell that there is something when the light is compared. ”

"Anyway...... Awesome! ”

"I feel that this shield is really invincible, originally the empty ship-2 flew high, and it was not easy to be locked, but now it simply can't be locked!"

……

Superconducting Materials Research Center.

Wang Hao continued to discuss with a group of scholars in various fields the technical issues of manufacturing micron-sized granular materials.

The way they discuss is that each person in their own field presents their views on micron-scale material technology and analyzes the macroscopic impact of semi-topology.

This kind of research is clearly biased towards theory.

Wang Hao found scholars in various fields to study together, and the purpose was to demonstrate from a theoretical point of view, so as to accumulate enough foundations.

At the same time, he also arranged experiments.

The Institute of Aeronautical Materials is responsible for the experiment, mainly because the Institute of Aeronautical Materials has sufficient equipment, environment and talents.

Wang Hao asked the Institute of Aeronautical Materials to help do the experiment, and naturally the research has been decided, and the name of the project is 'metal particle material technology'.

In terms of the Institute of Aeronautical Materials, Qu Gui and Cao Dongming participated in the research.

Qu Gui and Cao Dongming are both scholars in the field of alloys, and their research interests are metal composite materials and titanium alloys, respectively.

This collaborative experiment with the Institute of Aeronautical Materials is to study the behavior of liquid metal materials in special environments.

Wang Hao first looked for Cao Dongming.

Cao Dongming has been studying titanium alloys for a long time, and he was asked to do research on liquid metals in special environments, and the content is also very relevant.

Cao Dongming recommended Qu Gui again.

The two of them designed experiments together for research, and the content of the experiments was related to liquid metals, which required special environments such as high temperature, high pressure, and strong magnetism.

Experimental design is not easy.

Their research still started with conductors containing first-order lithium, which have relatively low melting points and are sufficient to create an environment of several hundred degrees Celsius.

After that, the temperature was gradually raised, and a lot of materials were used, including several superconducting materials containing first-order iron, but because the materials had to be melted, it was impossible to create a low-temperature environment for superconductivity.

Their research was unfounded, until the use of magnetized materials of pure iron.

The magnetized material of pure iron is directly supplied to the Institute of Aeronautical Materials by Annihilation Technology Company, and after continuous experiments have not been found, they simply place the magnetized material of pure iron in the furnace and then create a special environment of high voltage, but the manufacturing effect is very poor.

The resistance of a metal conductor is positively correlated with temperature.

To put it simply, the higher the temperature and the higher the resistance, and a high-temperature furnace of more than 1500 degrees Celsius can almost block the passage of current, and no matter how high the voltage is, it is of little significance.

However, when the voltage is applied, a magnetic field is created by the equipment, which affects the pure iron material in the high-temperature furnace, which can be regarded as creating a special environment.

This experiment was just interested in giving it a try, but it turned out to be an unexpected discovery.

Cao Dongming found Wang Hao for the first time and said excitedly, "We found that the first-order iron, when stirred, was separated from the conventional iron. ”

"At first, we didn't notice until the liquid metal cooled and solidified again, and we found that a lot of first-order iron was concentrated at the bottom of the material."

"Therefore, we think that during the stirring process, the first-order iron element produced a sinking ......"

“……”

Wang Hao thought about it carefully and immediately realized the problem.

The sinking of first-order iron is likely to be related to the specificity of first-order elements or the influence of conductor formation semi-topology under high pressure.

"Perhaps, both."

He thought about it and said to Cao Dongming, "I don't know if your discovery is related to your research, but congratulations on your ......."

"You may have discovered a whole new method of purification."

"Just creating a high-temperature, strong magnetic environment can separate the first-order iron, which is much simpler than other methods!"

Conventional first-order iron separation is a physical method.

The physical method is to create a high-temperature environment to melt the magnetized iron material, because the melting point of the first-order iron is higher than that of conventional iron, and this characteristic can be used to "sieve" the unmelted first-order iron.

This method sounds simple, but in reality, it is very complicated.

First of all, the first-order iron elements inside the magnetized iron material are evenly distributed, even after melting at high temperatures, they are still evenly distributed, and they cannot form a 'block' structure at all.

In addition, it is not easy to 'screen' melted first-order iron in an environment above 1500 degrees Celsius.

Therefore, it requires a lot of processes.

Now it is just to create a high-temperature, strong magnetic environment, with a maximum of a 'high voltage', and some iron can be separated by stirring, and the difficulty is naturally reduced a lot.

The less difficult it is, the lower the cost.

Cao Dongming was also very excited when he heard this, and whether their discovery was helpful for research or not, it could be used as the extraction of first-order iron, and the results were quite large.

Wang Hao is also very interested in new discoveries.

He decided to take time to go to the Institute of Aeronautical Materials to have a look, maybe he could see something he hadn't thought of from the experiment.

When the time comes, there will be progress in the research.

……

Now Wang Hao can't go over, after talking to Cao Dongming, he explained the work of the Materials Research Center, and then took a car to the Annihilation Force Field Experimental Base.

This time I went to receive the visiting team.

The team of Annihilation Technology Company who came to visit the experimental base was personally led by the general manager Zhong, as well as Professor Wang Jinlu, the core of the technology department, and other cutting-edge people in the field of technology.

They applied several times before they decided to visit the Annihilation Force Field Experimental Base.

Annihilation Technology Company is not an ordinary company, and the Technology Department is not something that can be entered casually, and everyone who enters the Technology Department is a scholar from the military and aviation group affiliated institutions, and most of them are from secret institutions.

Wang Jinlu is one of them.

Strictly speaking, he is an engineer and was elected to the Academy of Engineering three years ago.

The team of Annihilation Technology Company came to visit the Annihilation Force Field Experimental Group, and Wang Jinlu's strong request was also inseparable, they did manufacturing technology research and development, and they must have an in-depth understanding of the strong annihilation force field, and the company's manufacturing equipment is fixed and cannot be used in research and development at all.

Their past work has not yielded any results at all.

The equipment for the generation of the strong annihilation force field cannot be changed, only the equipment that transports materials above can be changed, but because they do not have sufficient understanding of the strong annihilation force field generation technology, they are just trying to improve the manufacturing process, so that until now, the annihilation technology company still has not achieved automated and rapid production.

When he arrived at the experimental base, Wang Jinlu immediately went to see the annihilation force field generation equipment.

Experimental equipment and manufacturing equipment are different.

The experimental equipment of the annihilation force field, all the complex structures are placed in front of you, and you can see it very clearly, but it is a pity that the experimental equipment is surrounded by the spiral magnetic field equipment, and you can't see anything at all.

Wang Jinlu had no choice but to find Wang Hao and keep asking technology-related questions.

Their R&D direction is to simplify equipment, improve manufacturing-related technologies, design manufacturing processes, and achieve more efficient manufacturing of magnetized materials.

Annihilation tech companies have not been established for long.

There is naturally no precedent for manufacturing in the field of new science and technology, and all related technologies must be accumulated slowly.

Now the problem of annihilation technology companies is that the material manufacturing pressure is high and the efficiency is relatively low, they have three strong annihilation force generation equipment, the field force strength is about 7.8 times, each equipment can only be turned on for two to three hours at a time, and it must be tested and maintained after it is closed.

The inspection and maintenance of equipment is a problem, and the manufacturing efficiency is also a problem.

The magnetization of lithium element compounds is just a matter of passing through the field force, and the same is true for magnetized iron materials, where the material is put into a strong annihilation force field and then taken out, the magnetization has been completed, and the time required is a few seconds.

However, due to the interference effect of the strong annihilation force field on electricity, equipment, and equipment, it is impossible to allow the transportation equipment to pass through the strong annihilation field, and they have not yet been able to design a device that can be used to transport materials, so they have not achieved an efficient manufacturing process.

This also has a direct impact on manufacturing efficiency.

Annihilation Technology Company has two products, one is magnetized iron material, and the other is magnetized lithium element compound, the latter is relatively better, and it can be transported in large quantities with a field force.

The former brings a lot of pressure.

At present, magnetized iron materials are most used in scientific research institutions, because iron itself is the most widely used metal, and there are many research and development directions.

For example, the Institute of Iron and Steel, the Institute of Aeronautical Materials and other institutions use magnetized iron materials in large quantities, and many studies do not do the extraction of first-order iron at all, and directly use magnetized materials for experiments, and the demand for magnetized iron materials is naturally very large.

Annihilation Technologies' manufacturing speed simply can't supply it, but they still have to sell a portion of it to the outside world to ensure that the company is highly profitable.

This is a problem.

Furthermore, there is the extraction of first-order iron, which is even greater than the problem above.

An important reason for the high price of first-order iron materials is that the extraction cost is high, and many scientific research institutions do not have the ability to extract magnetized iron materials.

Annihilation Technology Company will rely on the next-level departments to extract the first-order iron and then supply it to some important domestic scientific research institutions.

"Our extractions are far from keeping up with the supply ......"

Wang Jinlu shook his head and said, "The use of iron is too extensive, just in the direction of steel, alloy, etc., a lot of materials are needed. ”

"We also want to learn about the most advanced technology and see if we can improve manufacturing efficiency."

Wang Hao said, "Your equipment is already very advanced. With a force field of 7.8 magnification, there will not be much difference in the manufacture of at least first-order iron. ”

While the two were talking, Zhong Min Ge walked over.

He walked through the entire experimental room, carefully inspected the experimental equipment, and said with some regret, "It's a pity that your new technology can't be used in manufacturing." ”

"What you said last time, Academician Wang, I understand. This device really doesn't work! ”

Wang Hao nodded lightly and said, "There is really no way to manufacture magnetized iron materials, but the extraction ...... The Institute of Aeronautical Materials has developed a new technology, perhaps you should know about it, and maybe it can increase the extraction efficiency. ”

"Really?"

Zhong didn't care too much.

For Annihilation Technology companies, the extraction efficiency of first-order iron is improved, and it will hardly bring any benefits, because they do extraction for domestic scientific research departments, even if the extraction efficiency increases, it is still far from catching up with the demand.

He sighed and said, "It would be nice if we could directly make high-purity first-order iron." ”

"That's impossible."

Wang Jinlu denied, "Judging from the trend of content data, even if it is a strong annihilation force field with a rate of 20 times, the first-order iron content of the magnetized iron material manufactured will not exceed 20%. ”

After speaking, he looked at Wang Hao, as if he wanted to be recognized.

Wang Hao fell into thought, he was stunned for a long time, raised his head and asked Zhong, "What did you just say?" ”

Zhong smiled awkwardly, "I'm just talking about ...... casually."

"That's what I just said, what's impossible?" Wang Hao's expression was very serious.

"Making first-order iron?"

"What else?"

"Directly produce high-purity first-order iron ......?"

"Yes, that's it!"

Wang Hao waved his hand vigorously and said with surprise, "Make it directly!" Directly manufactured! Reasonable! Just because it's low doesn't mean it can't be manufactured directly! ”

"The magnetization of high-temperature liquid metals is also a good research direction."

"This may be related to semi-topology, or it may be related to specific phenomena......

He kept muttering in his mouth, and immediately made a decision, "I'm going to the Aviation Materials Institute!" Manager Zhong and Professor Wang, I can't entertain you for the time being. ”

"Leave your mind at your own devices!"

After Wang Hao finished speaking, he quickly left the experimental room.

Wang Jinlu said with admiration, "This is Academician Wang's attitude towards scientific research, and it really deserves to be Academician Wang...... If you have any ideas, you have to put them into practice immediately......"

Zhong was stunned.

He didn't sigh so much, but remembered that the last time he went to Xihai University, he just said a few words, and then Wang Hao left.

This time, or so?

He touched the corners of his mouth with his fingers and muttered, "This mouth is ......"

"Next time, I must not speak!"
