From university lecturer to chief academician.

The leader bluntly mentioned that in the military parade next year, he was looking forward to seeing the anti-gravity aircraft on the stage, which still surprised Wang Hao.

The in-depth research on anti-gravity is confidential, and the anti-gravity aircraft is naturally also confidential.

Why is the secret anti-gravity aircraft officially unveiled at a major ceremony of international concern?

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

The reason is simple - the key technology is kept secret, but the possession of high-end aircraft itself is not kept secret, not only is it not kept secret, but it must be displayed openly to let all other countries know.

In fact, the meaning lies in deterrence.

This is also one of the main purposes of the parade, which is to display the high-end weapons we have, such as high-end missiles, tanks, aircraft carrier technology, etc., after they are manufactured, they must be displayed.

This is actually related to the current international situation.

It is impossible for a super-large-scale war to take place in the world now, otherwise it is very likely to fall into the tragic scene of the earth being nuclear-flattened and the end of the world coming.

In some areas where wars really take place, it is impossible for the two major countries to be directly involved.The two big countries can only play games instead of fighting directly, otherwise the situation will be out of control 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 an aircraft, and it is only an aircraft and weapon that can be used in military affairs.

Its destructive power and deterrent power cannot catch up with intercontinental missiles with a large number of nuclear warheads anyway.

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

It is still impossible for big countries to really fight.

At the same time, it is still the deadliest nuclear weapon that plays a decisive deterrent role.

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

The emergence of anti-gravity aircraft does not have a direct impact on the situation of major countries, but excellent air power has an obvious effect on local disputes, so that it can be recognized by small countries in some regions, bringing influence, and may also bring some financial benefits.

These are all positive in nature.

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

"Nuclear research?"
"High-end aerospace weapons?"

On the way back to the West Sea, Wang Hao couldn't help thinking that maybe only the research on nuclear weapons and high-end aerospace weapons is the technology that can really play a decisive role, and it needs to be laid out silently and not disclosed at all.

These two areas...

"It seems that only research with strong annihilation power has potential..."

Wang Hao shook his head while thinking.

It is difficult to say the direction of development of strong annihilation force research, 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 is difficult to say.

"With more new discoveries, the research on strong annihilation force can be further advanced, and the application can be expanded 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 aircraft has improved compared to before, it can already take off and land autonomously, and it can fly horizontally at a slow speed, and its lift-off altitude has reached [-] meters.

This height seems to be nothing special, but it is actually a qualitative breakthrough.

When an aircraft can lift 100 meters into the air, it means that there is no problem at all below a thousand meters, but they only conduct a simple demonstration on the lift-off altitude, and there is no practical significance for testing.

The reason is simple - confidentiality.

Under the premise that the technology is not so perfect, they will not let the anti-gravity aircraft fly too high, otherwise they will
Will definitely let the world know the news.

Even the last [-]-meter lift-off was a test in no-man's land, and it took a lot of risk.

The current goal is to be able to demonstrate it in October next year. By that time, the technology must reach a certain level. The most basic aircraft can fly at high speed and have more flexible performance than ordinary fighters.

Of course, there is also technical stability, that is, no mistakes can occur during the display process.

With the promise of support from the No. [-] leader, the manufacturing time of some design components will definitely be greatly shortened, and the research on the aircraft can be increased.

That’s what Wang Hao thought. He summoned the technical team leader and all the people in charge, and immediately set the next goal. “We can now take off and land normally, and fly horizontally at low speed, but there are still many problems.”

"I won't say much about the problems in the electronic system. We must continue to improve in this regard, and we must solve any problems we encounter."

"In addition, we will begin to demonstrate the acceleration, high speed flight and deceleration of the aircraft."

"Also, flexibility is a big problem."

"Now we use electric propellers for steering. This design is too rough, and it also greatly limits flexibility..."

The electric propeller is installed below the nacelle, and the four propellers responsible for steering are installed in the middle of the nacelle.

Compared with the entire aircraft, the propeller is very small, and the position where the force is exerted can even be counted as a point. If the force is exerted at one point, the force is suddenly too large, and it may even cause the entire aircraft to roll over.

Therefore, the electric propeller responsible for steering can only reduce the power as much as possible, and the power given at the beginning of the rotation is even gradually increased from zero.

This leads to severe restrictions on the flexibility of the aircraft, and steering has become a big problem.

In the next few days, Wang Hao began to convene everyone for demonstrations, asking them to think of some other steering methods, and many people found inspiration from fighter jets.

The wing, was the most proposed idea.

"If a steering wing is installed above the main cabin, it can be controlled to make the aircraft automatically turn."

"We can design the electric propeller to only run in one direction, flying forward like an airplane, and the wings control the direction..."

The idea works.

Now normal airplanes are like this, the engine is fixed, and it only runs in one direction, and will not give force in other directions. The steering of the airplane depends on changing the direction of the wings, just like a sailboat in the sea. The direction of the sail can change the direction of sailing.

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

"If the steering method of an aircraft is used, its flexibility will definitely not be able to catch up with conventional fighter jets."

"The flexibility can't even catch up with conventional fighter jets, so what's the point of our research?"

The others were immediately speechless.

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

Later, a doctor of mechanics named Zhou Chang made an interesting suggestion, "Can we make the aircraft rotate rapidly as a whole?"

"Like some UFOs..."

The image of a UFO flying saucer spinning continuously in the air suddenly appeared in many people's minds, and they 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 he already had it.

Thinking from the direction of theoretical design, Zhou Chang’s suggestion is indeed feasible. When the aircraft is about to turn, it should rotate rapidly as a whole. The faster the rotation speed, the faster the turn will be.

The physical logic in it can refer to the continuously rotating football. When the football continues to rotate, the trajectory across the air is an arc.

This is mainly because the speed of the two ends of the rotating football relative to the air is different. The side with the higher speed has a lower overall pressure on the ball.

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

However, there are still technical problems ahead. It is not a problem to make the aircraft rotate as a whole. No matter how the rotation of the aircraft is designed, the main compartment where the pilot is located, that is, the most central position, must not rotate.

So the biggest problem is the main bearing pressure capacity.

After turning on the anti-gravity weight reduction of the entire aircraft, the weight will still exceed two tons, and the continuous rapid rotation will definitely challenge the pressure capacity of the main bearing.

In addition, it will also cause some other problems.

For example, most parts of an aircraft will bear the pressure brought by high-speed rotation, and will form an angular momentum pointing to the center. The faster the rotation speed, the greater the angular momentum.

Then each component must be fixed, and there cannot be any position changes during the rotation.

There may also be some magnetic field or other collateral effects when the internal electronic system is running and spinning.

These are questions.

For all the incidental problems, everyone worked together to discuss and solve them. In the end, it was the main shaft problem that was difficult to solve. The performance of the current main shaft is not enough. In addition to the fast rotation of the steering, a super performance and long service life is needed. spindle.

In the eyes of many people, this problem cannot be solved at all.

……

Wang Hao is not sure whether the problem can be solved, he still depends on the performance of the spindle manufactured by Hanshi Industry.

Now the Anti-Gravity Behavior Research Center has cooperated with Wuhan Iron and Steel Co., Ltd., and uses the high-strength superposition stand to continuously magnetize the materials shipped by Wuhan Iron and Steel.

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

There will be news soon.

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

The final test result was told by Wang Jiming directly to Wang Hao. His tone was so excited that he even fainted from 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 stronger!"

"It's simply unbelievable. I even went to the testing room and did a test with my hands. It's hard to hit a mark on that kind of steel with a hammer..."

"Although there is no specific data yet, and a lot of testing is still to be done, but it is absolutely amazing..."

After hearing this, Wang Hao also let out a sigh of relief.

In many studies, he generally has and expected in his heart, but it is really difficult to predict the manufacturing of bearing steel, because he only 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 is just like what Wang Jiming described, "it's hard to make a mark with a hammer."

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

Wuhan Iron and Steel produced the first batch of 'special bearing steel', some of which were used for testing, and most of them were shipped to Hanshi Industry.

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

Although there is still a need for constant waiting, the expected time has indeed been greatly shortened.

This reflects the role of the No. [-] leader. As soon as he opened his mouth, 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 alone may delay for another half a month. They are not deliberately delaying, but want to conduct detailed inspections just now to confirm that they can be used to produce high-end bearings.

Because of the major confidentiality issues involved, it will definitely take some time for the special bearing steel to go from Wuhan Iron and Steel to Hanshi Industrial's factory, and it even needs military-military coordination to escort it. At the same time, we must also pay attention to the impact on the surrounding area.

As for Hanshi Industry, it will not cooperate at the first time, but must spare time for production and manufacturing under the condition of regular production.

and many more.

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

Wang Hao waited for the manufacture and delivery of the spindle, and also cared about other research.

Strong annihilating power.

The research on the strong annihilation force was also in a waiting process before.

What they are going to study is the new discovery made public by Philip's team, namely that the high magnetic field makes the antigravity field deflect.

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

Therefore, the research group cooperates with the Institute of High Energy, and the Institute of High Energy will provide magnetic field manufacturing devices and help build a large enclosed space with high magnetic fields.

It takes a long time to wait for the latter to be built.

The former, that is, the magnetic field manufacturing device, has been transported to the Antigravity Behavior Research Center.

This magnetic field manufacturing device also looks very powerful. It is about five meters high and can half cover the large superimposed force field device. After the installation is completed, it can cover the center superimposed force field as a whole.

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

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

As he spoke, he sighed, "It's really amazing. Only superconducting technology can sustain such a high-intensity magnetic field."

Wang Hao nodded in satisfaction.

The magnetic field strength at the center of this device also exceeds 6T, and the magnetic field can be maintained continuously, which is indeed quite remarkable.

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

Ordinary strong currents can also produce high-intensity magnetic fields, but they are not so economical. Both the cost of the device itself and the power consumption are very alarming.

Because the technology for manufacturing the superimposed force field has been stabilized, testing the device directly enters the experimental process. Simply put, the superimposed force field device is turned on at the same time.

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

But the result was very unexpected.

During the device test, Wang Hao was standing in the safe room when he heard Wang Shanqing's voice in the headset, "The magnetization response of this group of materials is much stronger than the previous data, even twice as high as the previous data. 1.7T!"

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

"Won't."
Wang Shanqing affirmed, "Ordinary metals will not be affected if they leave the high magnetic field environment, and they will not be magnetized, so I conclude..."

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