From university lecturer to chief academician.

Xihai City, Aviation Industry Group, the experimental base of the anti-gravity aircraft research group.

A large anti-gravity device is placed in the hall of the base. The device is a disc-shaped structure with a diameter of about 20 meters, which is supported and placed in the air.

Standing under the large installation, looking at it from a close distance gives people a great sense of awe.

Wang Hao also looked forward to the next test.

This test experiment looks very simple. In fact, the technical difficulty is still very high. It is not just as simple as the propeller suspending the anti-gravity device.

A middle-aged man with a cropped cut was standing next to Wang Hao, introducing the suspension test experiment.

He is Duan Qingbai, the head of the technical team.

Duan Qingbai was talking, "We have two main points for this test, one is the electric propulsion, and the other is the balance system."

"There is a third point, but it is very unstable now, it is the automatic control and gravity adjustment system."

"In terms of automatic control and gravity adjustment, our backstage is not doing very well."

Duan Qingbai shook his head while speaking.

Any electronic technology will become very complicated when it comes to automatic control, but the main difficulty of the current test lies in the electric propulsion.

If the electric propulsion can run stably, it is relatively easy to modify the automatic control system.

Wang Hao also listened and nodded, he naturally knew the difficulty of the test experiment.

The most important thing about this test is the four electric thrusters under the anti-gravity device. Generally, the thrusters used in aerospace are rocket thrusters, which use solid or liquid fuel as the power source. Relatively speaking, the electric thrusters are still rare.

The anti-gravity device is most suitable to use electric propulsion.

The reason is also very simple. Exciting the transverse antigravity field requires high-power current transmission. Electricity is a natural energy source, and there is no loss in superconducting materials.

In this way, its high power current can be used to support the operation of other supporting equipment, otherwise the power will be consumed in vain.

Duan Qingbai continued to talk about technical difficulties and problems encountered in research and development.

Wang Hao kept thinking, "If SMES batteries are used as power, one needs to be supplemented by battery power, and the other is only coolant."

"For highly compressed coolant, liquid nitrogen is sufficient."

"The nitrogen gas sent out after cooling can also be discharged directly in the air, and it is non-polluting... A flying device that consumes electricity and liquid nitrogen should be considered environmentally friendly?"

Wang Hao felt a little hopeful when he thought about it.

Next, he watched the suspension test experiment of the anti-gravity device.

He has not participated in related research, but has some understanding of the progress of the research.

After the experiment officially started, the anti-gravity device was powered on, the electric propulsion and the electronic system were turned on, and a buzzing sound was heard under the equipment.

Electric propulsion is to use electricity to make the fan blades push the air to obtain upward thrust. There is no difficulty in theory, but the actual difficulty is still very high.

Several electric thrusters are of the latest design, and the fan blades used are all made of special nickel-iron alloy. The biggest technical difficulty lies in power control.

Simply put, four electric thrusters must work in harmony to ensure the balance of the entire anti-gravity device.

"Our method is to select a balance mark, and if the balance mark has an inclination angle, let the electric propeller on one side increase the horsepower."

"But it was still very unstable after a few tries, and a series of adjustments were made. This time it should be better..."

Duan Qingbai was a little nervous as he spoke.

At this time, the operation of the electric thrusters reached a certain value, and one side of the anti-gravity device rose tremblingly.

Many people watched anxiously, fearing that only one side of the device would lift up, or that there might be some other major failure.

Fortunately, the other positions also rose quickly, and the entire equipment was pushed to slowly hang in the air, but the trembling of the device could be clearly seen, and one side was slightly higher than the other positions.

This inclination is very obvious, and it must be something wrong with the balance mark, background system or electric propulsion control.

The whole device is half a meter above the ground, suspended

In about 3 minutes, Duan Qingbai hurriedly announced that it had stopped.

"Prepare to land!"

He hurried to the side to direct the landing control.

The process of launching the whole device is already very complicated, and the process of landing is even more complicated.

In order to ensure the safe landing of the device, the power of the electric propulsion must be slowly reduced, and the position must be adjusted to prevent any accidents.

At the same time, they have to carry a higher bracket and place it under the anti-gravity device. The distance of half a meter into the air is not high, but considering that the anti-gravity device exceeds forty tons, even if it is only half a meter from the ground, the power failure or If other problems arise, it will be a huge experimental accident.

Wang Hao watched the whole test process, and he was very satisfied with the overall test. With the balance control system and electric propulsion, it means that there is no problem on the whole.

Now the main thing is background power delivery and automation control.

There are no insurmountable technical difficulties for these soft problems.

After all the experiments were over, Duan Qingbai also talked about design issues with Wang Hao, "We have several plans for the design of the anti-gravity vehicle."

"One of the plans is to install a large fan blade under the propeller. When the device is officially launched, the rotation of the fan blade can be used to drive the device. Several electric propellers are just to ensure balance."

"In addition, there is another design plan, which is in..."

Duan Qingbai continued to introduce.

Wang Hao was also very interested. He suggested, "Haven't you guys considered superconducting motors? If the propeller is made of superconducting motors, the power will definitely be higher."

Duan Qingbai shook his head and said, "The superconducting motor has been researching and developing, but it is not stable yet. Now we mainly focus on improving the balance system. The power of the motor is already enough."

This is a fact.

At this stage, it is just to lift the anti-gravity device into the air.

When the technology is truly mature, the demand will definitely become different. For example, if you need to manufacture a large anti-gravity carrier aircraft, you need a higher propulsion force, and you will consider replacing a higher-power electric propulsion.

It is still too far to talk about these at present.

Wang Hao thought for a while and said, "The biggest problem to be solved at present is electricity."

"really."

Duan Qingbai smiled wryly, "If the power problem is not solved, the aircraft will not be able to operate at all. We have thought about using lithium batteries, but the power is still too bad."

"The most efficient battery pack can only barely drive it..."

Wang Hao said with a smile, "Lithium batteries are definitely not good. They must be superconducting batteries. It just so happens that we are also researching SMES batteries. I think we can combine research together."

"Merged studies?"

Duan Qingbai opened his mouth wide in surprise, "Isn't your SMES battery still in the design stage?"

Wang Hao shook his head and said, "We already have a new type of energy storage coil technology, and electronic control has also made great progress. What is missing now is the packaging, do you understand?"

"In other words, the overall design of the battery has been completed, and there are no technical difficulties. The only difference is the last step."

"Isn't it?" Duan Qingbai finally realized, "It means that your design demonstration has just been completed, and you have just overcome some technical difficulties..."

Shouldn't the next step be test perfection? "

This is the normal research process.

It's like researching an engine. The first thing to do is to design the engine, overcome technical difficulties in the process, and the next step is to manufacture samples.

After the sample of the engine is produced, normally one-third of the research is completed. After the sample is produced, there will definitely be various problems, and the remaining two-thirds are to improve the engine.

The current SMES battery is also similar. The battery design is completed and various technical problems have been solved, but the solution to the problem is only theoretical. The next step is to manufacture samples and then continue to test and improve.

Wang Hao patted Duan Qingbai on the shoulder and said, "Don't worry, I am very confident in the energy storage coil and the electronic control system."

"Before I thought about continuing to improve, but now I see you

I think their progress can be merged together. "

"If we work together, we can skip the packaging design stage directly, and all parts of the entire battery are embedded in the anti-gravity aircraft, and then the battery can be used as energy."

"Duan Gong, have you forgotten?"

Wang Hao said with a smile, "Our battery research is mainly to support anti-gravity aircraft!"

"……Right."

Duan Qingbai twitched his lips and remained silent for a long time, obviously unacceptable, but finally nodded.

The reason is very simple, it is Wang Hao who is speaking in front of him.

Wang Hao is not involved in the overall design of the anti-gravity vehicle, but he holds the title of chief of the experimental team.

The anti-gravity vehicle experiment group used the anti-gravity technology from the Anti-Gravity Behavior Research Center.

That is the real core technology.

Duan Qingbai is the person in charge of the technical group and only the deputy chief engineer of the project.

Wang Hao is the most direct person in charge, but the project he is mainly responsible for is the research of SMES batteries.

In fact, it's not just a matter of position. Wang Hao's personal influence is also very large. When he said that he wanted to merge the projects, even if Duan Qingbai had no confidence in the so-called 'SMES battery, he would definitely nod his head in approval.

The good news is...

If the projects do come together, Wang Hao will definitely be involved in the work on the anti-gravity vehicle.

At that time, if you encounter any problems, you can discuss and solve them together.

……

Teng Jianjun, deputy general manager of the Aerospace Industry Group headquarters, is in charge of the research and development of new technologies. He has received the electric propulsion and balance test experiment report submitted by the anti-gravity vehicle research group.

Teng Jianjun attaches great importance to the research of anti-gravity aircraft.

Even internationally, it is believed that anti-gravity technology is the mainstream technology of aerospace in the future, and it is also a technology that can directly change the aviation pattern.

After reading the experiment report, Teng Jianjun couldn't help pressing his forehead hard, "The progress is normal, but the most important thing is the power problem!"

He naturally knows the key to technology.

The operation of the anti-gravity system needs high-power electric support. Even if the research progress of the anti-gravity aircraft is fast, without high-power electric support, it is just a building in the sky.

He hurriedly looked at the report submitted by the SMES battery research group.

That was already a report half a month ago. The report was an explanation of the energy storage coil test. Basically, it can be considered that the new energy storage coil technology has been perfected.

"The technology of the new energy storage coil is perfect, but it is estimated that it will take three or five years before the SMES battery is perfect?"

"In addition to the test of the anti-gravity vehicle, it will take a few years..."

Teng Jianjun thought for a while and shook his head, "I don't know if we can see an anti-gravity vehicle take off in ten years, even if it's just a test flight."

He touched the gray hair on his head, and his face could not help showing sadness.

He hoped to see the anti-gravity aircraft, but he was nearly 60 years old and approaching the age of retirement, so he didn't know if he would still be able to see it.

Teng Jianjun decided to go to Xihai City after thinking about it, just to get a comprehensive understanding from the experiment report.

If you can visit the experimental base, you can know what kind of technical difficulties the research has encountered.

In addition, it is also possible to know the progress of research and development, not only the research work of anti-gravity aircraft, but also the research of SMES battery is very important.

Technology Department.

Xu Baogong and Teng Jianjun had the same idea, and also wanted to see the progress of the experiment in Xihai City, but he mainly went to the SMES experimental base to understand the follow-up testing of the SMES energy storage device.

At present, the country is demonstrating the construction of large-scale SMES energy storage devices, and has decided to put the pilot project in Sudong Province, a large electricity consumer.

Sudong Province is close to Donggang City, and both provinces and cities need external transmission for electricity consumption.

If a super-large SMES energy storage device can be built at the junction of Sudong Province and Donggang City, it will be able to more stably ensure continuous electricity demand, then the improvement of related technologies is very important.

As for SMES batteries...

Xu Baogong didn't even dare to think about it. He also saw the report of SMES battery research, but he only perfected the new energy storage coil technology. It is still very far away from making a real SMES battery.

Think about...

The Institute of Electrical Engineering of the Academy of Sciences had the technology of superconducting energy storage coils at the beginning, and the Superconducting Material Industry Company also provided the best materials, but it took Pan Dong's team two years to design the experimental device.

After that, I faced a lot of problems, and it seemed that there was no way to solve them.

Wang Hao's research group has made rapid progress. It only took a few months to perfect the SMES power storage technology, but the SMES battery is more complicated than the SMES energy storage device, and it is bound to encounter more problems.

It is still too early to talk about SMES batteries, and it is already remarkable to be able to overcome the foundation of new energy storage coils.

Xu Baogong knew Wang Hao better, and his judgment was much more optimistic than Teng Jianjun. "It will take two years to perfect the battery technology, right?"

"Anyway, I'm going to have a look..."

"Just two more months!"
