The leader bluntly said that at next year's parade, he was looking forward to seeing the anti-gravity aircraft debut, which still surprised Wang Hao.

The advanced research on anti-gravity is of a confidential nature, and anti-gravity vehicles are naturally also secret.

Why did you make the official debut of a secret anti-gravity vehicle at a major ceremony of international attention?

Wang Hao talked to the leader again, and with his own thinking, he could almost understand.

The reason is simple - the key technology is kept secret, but the possession of a high-end aircraft itself is not a secret, not just not a secret, but it must be displayed openly and openly so that all other countries know about it.

In fact, the meaning lies in deterrence.

This is also one of the main purposes of the military parade, which is to display the high-end weapons it has, such as high-end missiles, tanks, aircraft carrier technology, and so on.

This is actually related to the current international situation.

At present, it is impossible for a super-large-scale war to take place in the world, otherwise it is very likely to fall into the miserable scene of the earth being leveled and the end coming.

In some areas where real wars are taking place, it is unlikely that the parties directly involved will be the two major powers. The two great powers can only play a game, rather than directly fighting each other, otherwise the situation cannot be controlled, and it may bring disastrous consequences.

The anti-gravity aircraft does sound very high-end, but no matter how high-end the technology is, it is only a flying machine, and it is only an aircraft and weapon that can be used for military affairs.

Its destructive power and deterrent power will not be able to catch up with ICBMs with a large number of nuclear warheads.

Therefore, the emergence of anti-gravity aircraft only let the world know that the flower growers have the most high-end and advanced technology aircraft, which cannot play a decisive role in the entire international situation.

It is still impossible for the major powers to really fight.

At the same time, the decisive deterrent is still the most lethal nuclear weapon.

Therefore, when there is military-military technology, it must be displayed, and only by showing it can everyone know about it and play a deterrent role.

The emergence of anti-gravity aircraft cannot have a direct impact on the situation of major powers, but excellent air power has an obvious role in local disputes, so that it can be recognized by small countries in some regions, and at the same time, it may also bring some economic benefits in the future.

These are of a positive nature.

"So, what kind of technology needs to be completely secret in order to be decisive?"

"Nuclear research? ＂

"High-end space weapons?"

On the way back to the West Sea, Wang Hao couldn't help but think that perhaps only the research of nuclear weapons and high-end aerospace weapons is the technology that can really play a decisive role, and it is the technology that needs to be laid out silently and completely not made public.

These two areas ......

"It seems that only research on strong annihilation has potential......

Wang Hao shook his head after thinking about it.

It is difficult to say the development direction of strong annihilation research, and what can be found at present is related to alloy manufacturing, that is, it can be applied to materials science.

As for the follow-up, it's hard to say.

"Only with more new discoveries can the research on strong annihilation be further advanced and can be extended to various fields."

……

Wang Hao returned to Xihai, only rested at home for a day, and went directly to the research and development base of anti-gravity aircraft.

Now the anti-gravity vehicle has been improved compared with before, and can take off and land autonomously, and carry out slow horizontal flight, and the altitude of the lift has reached 100 meters.

This height may not seem remarkable, but it is actually a qualitative breakthrough.

When an airplane can rise 100 meters, it means that there is no problem below the kilometer altitude, but their altitude is only a simple demonstration, and there is no practical significance to do testing.

The reason is simple - secrecy.

On the premise that the technology is not so perfect, they will not let the anti-gravity vehicle fly too high, otherwise

Sure to let the international know the news.

Even the last time it was lifted 100 meters, it was a test in a no-man's land, which was very risky.

The goal now is to be able to demonstrate it in October next year, when the technology will definitely reach a certain point, and the most basic aircraft can fly at high speeds and have more flexibility than ordinary fighters.

Of course, there is also technical stability, that is, there must be no mistakes during the presentation.

With the commitment of the support of the second leader, the manufacturing time of some design components will definitely be greatly reduced, and the research efforts of the aircraft can be increased.

That's what Wang Hao thought, he convened the leader of the technical team and all the people in charge, and immediately formulated the next goal, "We can now achieve normal take-off and landing, low-speed sideways, but there are still many problems."

"There is not much to say about the problems of the electronic system, we must continue to improve this aspect, and solve whatever problems we encounter."

"Also, we're going to start demonstrating the acceleration, high-speed flight, and deceleration of the aircraft."

"Also, flexibility is a big issue."

"Now we use electric propulsion for steering, which is too rough and has a lot of flexibility......

The electric thrusters are installed under the nacelle, and the four steering thrusters are located in the middle of the nacelle.

The thruster is very small compared to the whole aircraft, and the position of the force can even be counted as a point, and a point to exert force, suddenly the force is too large, and it may even cause the entire aircraft to overturn.

Therefore, the electric thruster responsible for steering can only reduce the power as much as possible, and the power given at the beginning of the rotation can even be slowly increased from scratch.

As a result, the flexibility of the aircraft is severely limited, and steering has become a big problem.

In the following days, Wang Hao began to gather everyone to argue, asking them to think of some other ways to turn, and many people looked to fighter jets for inspiration.

The wing, is the idea that has been put forward the most.

"If you install a steering wing above the main compartment, you can control the aircraft to turn automatically."

"We can design the electric propulsion to move in only one direction, like an airplane flying forward, with the wings controlling the direction......

The idea is doable.

Now normal airplanes are like this, the engine is fixed, only in one direction, will not give force in other directions, the steering of the aircraft depends on changing the direction of the wings, just like a sailboat in the sea, changing the direction of the sails, you can change the direction of sailing.

Wang Hao directly rejected this idea, and the reason he gave was very simple, "We are studying anti-gravity aircraft, not conventional aircraft."

"If you use the steering method of an airplane, it will definitely not be as flexible as a conventional fighter jet."

"Flexibility can't even catch up with conventional fighters, so what's the point of our research?"

The others were speechless for a moment.

Wang Hao didn't have any good ideas, so he could only let everyone use their brains together.

Later, there was a doctor of mechanics, named Zhou Chang, who made a very interesting suggestion, "Can we make the whole aircraft rotate quickly?"

"It's like some UFO......

Many people suddenly had a UFO disc in their minds, and the image of the continuous rotation in the air almost subconsciously felt that the suggestion was unreliable.

Wang Hao's eyes lit up when he heard it, what he lacked most was inspiration, and inspiration was already there.

Thinking from the direction of theoretical design, Zhou Chang's suggestion is indeed feasible, when the aircraft is to be turned, the whole should rotate rapidly, and the faster the rotation, the faster the steering will be.

The physical logic can refer to the constantly rotating football, when the football is constantly rotating, the trajectory that crosses the air is an arc.

This is mainly because of the fact that the speed of the two ends of the ball relative to the air is different in the spinning football, and the side with the greater velocity has less pressure on the ball as a whole, and the two sides

The force is naturally different, and the trajectory of the arc will appear.

However, technical problems are also in front of us, so that the overall rotation of the aircraft is not a problem, even if the rotation of the aircraft is designed, the main cabin where the pilot is located, that is, the most central position, will definitely not rotate.

So the biggest problem is the pressure capacity of the main bearing.

After the whole aircraft is turned on anti-gravity weight reduction, the weight will still exceed two tons, and the continuous rapid rotation will definitely be a challenge to the pressure capacity of the main bearing.

In addition, there are some other problems that can arise.

For example, most of the parts of the aircraft will be subjected to the pressure caused by high-speed rotation, which will also form an angular momentum pointing to the center, and the faster the rotation, the greater the angular momentum.

Then each part must be fixed and there should be no change in position during the rotation.

When the internal electronic system is still rotating while it is running, some magnetic fields or other collateral effects may also occur.

These are all questions.

For all the incidental problems, we work together to discuss and solve, and finally it is difficult to solve the problem of the spindle, the current spindle performance is no longer enough, coupled with the rapid rotation of the steering, it needs a spindle with super performance and super service life.

In the eyes of many, this problem simply cannot be solved.

……

Wang Hao is not sure whether the problem can be solved, he still has to look at the performance of the spindle made by Hanshi Industry.

At present, the Anti-Gravity Properties Research Center has cooperated with WISCO, and has continuously magnetized the materials transported by WISCO by using the high-strength superposition position.

Wuhan Iron and Steel uses magnetized materials to manufacture special bearing steels.

News soon followed.

The first batch of magnetized materials shipped back has been made into ingots, and the properties of the steel have been tested.

The final test result was said directly by Wang Jiming to Wang Hao, his tone was very excited, and he felt that he was even fainting with excitement.

"2.2 to 2.4pp"

"Academician Wang, do you know what this data represents?"

"This super steel is more than twice as tough as the previous steel, and even more than three times tough!"

"It's incredible, I also went to the testing room and did a test, and it's hard to make a mark with a hammer on that kind ......of steel."

"Although there is no specific data yet, and there are still a lot of tests to do, it is absolutely amazing......

Wang Hao also exhaled lightly when he heard this.

In a lot of research, he generally has and mentally expected, but the manufacturing aspect of bearing steel is really difficult to predict, because he just added a process to determine that the oxygen content of the steel can be reduced.

Theoretically, when the oxygen content of steel is reduced, the impurity content will be greatly reduced, which will greatly improve the toughness and service life.

The so-called toughness, as Wang Jiming described, 'It is difficult to smash the mark with a hammer,'

In the process of a bearing operation, to withstand a huge offset force for a long time, the bearing steel must have enough toughness, that is, under the action of various bumps and pulls, the shape will not change, and the manufactured bearing can have sufficient performance and service life.

WISCO produced the first batch of special bearing steels, some of which were used for testing, and most of which were shipped to Hanshi Industry.

Hanshi Industry will use their production line to use this batch of special bearing steel for confidential production to manufacture the spindle required for anti-gravity aircraft, and the manufacturing time will be more than half a month.

Although there is still a constant wait, the expected time is indeed much shorter.

This reflects the role of the No. 2 leader, as soon as he speaks, he asked several departments to coordinate and cooperate to jointly and quickly manufacture the required bearings.

If there is no high-level leadership to speak, Wuhan Iron and Steel may delay for another half a month, they are not deliberately delaying, but to carry out detailed testing just now, to determine that it can be used to produce high-end bearings.

Because of the major confidentiality issues involved, it will definitely take a while for special bearing steel to go from Wuhan Iron and Steel to the factory of Hanshi Industry, and even need to be coordinated and escorted by the military, and it is also necessary to pay attention to the impact on the surrounding area.

In terms of Hanshi Industry, it will not cooperate at the first time, but to ensure that it takes time out for manufacturing under the condition of conventional production.

Wait a minute.

Now, the time spent on manufacturing has been greatly shortened, and the anti-gravity vehicle research team can obtain the bearings produced under strict supervision in the shortest possible time.

Wang Hao waited for the spindle to be manufactured and delivered, and also cared about other research.

Strong annihilation.

The study of strong annihilation was also in a waiting process before.

What they set out to study was the new discovery that Philip's team had made public, namely that the high magnetic field caused the antigravity field to be shifted in direction.

Wang Hao believes that the directional shift of the anti-gravity field is directly related to the characteristics of the edge region, and can be studied in combination with the superposition force field.

Therefore, the research group cooperated with the High Energy Institute, which will provide a magnetic field manufacturing device and will also help build a large 'high magnetic field enclosed space,'.

The latter will have to wait a long time to build it.

The former, the magnetic field fabrication device, has been transported to the Anti-Gravity Properties Research Center.

This magnetic field manufacturing device also looks very shocking, about five meters high, can semi-cover the large superimposed force field device, after the installation is completed, it can cover the most central superimposed force field as a whole.

The technicians sent by the High Energy Institute also introduced to Wang Hao, "We have been studying this device for a long time, and it also uses superconducting technology."

"The magnetic field strength at the inner edge of the device is the highest, reaching about 10 tons, and the center is about 6 tons, so as long as there is enough power supply, the magnetic field can be maintained."

He also sighed, "It's really amazing, and only superconducting technology can sustain such a high-intensity magnetic field."

Wang Hao nodded with satisfaction.

The magnetic field strength at the center of this device is also more than 6T, and the magnetic field is able to maintain continuously, which is quite remarkable indeed.

In fact, sustained high-intensity magnetic fields can only be manufactured economically using superconducting technology.

Ordinary strong current can also create high-strength magnetic fields, but it is relatively not so economical, whether it is the cost of the device itself, or the power consumption, it is very amazing.

Because the technology for creating the superimposed force field has been stabilized, testing the device directly enters the experimental process, which is simply to turn on the superimposed force field device at the same time.

I thought it was just a test of the device, but when I turned on the superposition position, the device was only symbolic, and I didn't plan to really discover anything.

But the result was very unexpected.

During the device test, Wang Hao stood in the safe room and heard Wang Shanqing's shout from the headset, "The magnetization reaction of this group of materials is much stronger than the last data, and even exceeded twice as much, reaching 1.7T!"

Wang Hao immediately asked, "Could it be the influence of the high magnetic field environment?"

"No, it won't. ＂

Wang Shanqing affirmed, "When ordinary metals leave the high magnetic field environment, they will no longer be affected, and they will not be magnetized, so I conclude that ......."

"It must be the edge of the superimposed force field, which has produced some kind of change!"
