Chapter 172 The Principle of Suspension
Everyone saw the scene of the battle clearly, and the tragedy of the war also appeared in front of everyone. When the rocket hit Ron's face, they were surprised when they saw the intact glass surface !
Only 10 cm thick glass!What kind of concept is it to actually bear the attack of rockets!If this is done in various composite armors, how effective it will be on the battlefield!
"Of course, the melting point of glass is between 600 and 1000 degrees. Adding metal materials to increase the melting point of the glass and applying it to the military field is also an important project for us in the future."

Zhu Cheng explained that this kind of glass has its limitations, that is, the temperature of the melting point, and there are still a few steps to go before it can be used on the battlefield, but the powerful performance alone has already made people watching the live broadcast, Feel out its prospects.

"This glass is the most important reason why our technology center and the rotating building can fly. The density of glass is 2200 kg to 2800 kg per cubic meter, while steel is 7850 kg per cubic meter! Even titanium alloy is 4510 kg per cubic meter. Cubic meters! The density of metallic glass is extremely low, but it has excellent performance in other aspects, and it is lighter after being foamed!"

"The entire building uses 2 cubic meters of metal glass, and weighs only 4 tons. This weight ensures that our technological aircraft can take off perfectly!"

"Aren't you very curious, what principle is used to fly 4 tons of things? Let me show you."

As Zhu Cheng spoke, he took out a plate and a spinning top. These two items are props for him to demonstrate the principle. They can be found everywhere in the market, and they are both good and cheap.It is called a magnetic levitation top toy, the disc is a permanent magnet, and there is also a permanent magnet under the top.

"When we spin hard, this top can float in the air, it will not turn somersaults in the air, and it will not run out, because of the conservation of angular momentum. According to Enshaw's law, any combination of electrostatic force, static magnetic force, and gravitational force cannot Let an object be in a stable state, and the potential energy generated by all electrostatic fields, static magnetic fields and gravitational fields on a charged body or a magnet is in the shape of a saddle. That is, it is impossible to suspend a small magnet in the air by these three forces. It's always going to go in a certain direction."

He demonstrated that the small top was ejected from the disk without any accidents without spinning.This sheath-type potential energy cannot stabilize the object at all.

"The reason why this toy is balanced is to transform the saddle-shaped potential energy into a bowl-shaped potential energy. Let our technology center maintain a stable flying posture in this potential energy. And this potential energy transformation, through Michael Berry's demonstration that this bowl-shaped potential well occurs in a very small region above a magnet."

"For example, in our toy, the diameter of the magnet base is 6 centimeters, and the balance range is between 3 and 3.8 centimeters. Therefore, the weight of the levitating top must be adjusted just right to be able to levitate in this range. If it is too light or too heavy, the levitating gyro If you can’t balance in this range, you will fly out.”

"This bowl-shaped potential energy is the key to our flight! Of course, the technology inside is very complicated, and we have to overcome the influence of the earth's rotation! Overcome huge energy consumption! Overcome the role of bowl-shaped potential energy force!"

The huge energy consumption is due to the use of Cree's flywheel battery technology. Under this technology center is a huge magnetic field, and this rotation can be like the rear wheel of an electric car, while converting power generation, to overcome a certain amount of energy consumption. The problem.

Of course, there is also the cable he pulled over in cooperation with the country. This cable goes straight to the Panzhihua Nuclear Power Plant!To this end, he also delivered a breeder reactor technology for Panzhihua Power Plant.

There is also an isolation magnetic field. A huge magnetic field can distort a metal. Similarly, if a person is exposed to a strong magnetic field for a long time, it will also cause biological secretion disorder. This material that isolates the magnetic field is also a high-priced product.After overcoming various difficulties, the flight center was able to fly completely.

"This is an epoch-making product created by the linkage of engineering, materials science, electromagnetism, biology and other disciplines! It represents a new era!"

Zhu Cheng's voice is small, but very penetrating.This kind of low voice is not that he has no confidence, but that everyone knows that his technology is already at the pinnacle of the earth!

Career is fully capable and has won the honor of the World Science and Technology Center!
Everyone quietly watched the rotation of the metal shell on the outer ring, which was the source of power to levitate.Glass structure, light and durable than metal,

This cross-century product appeared in front of them, making them feel as if they had traveled through a world and walked into a future world.

"Gentlemen and ladies. This press conference has just started, and there are still bigger surprises waiting for us! This is a press conference about changing the way of travel, and this is a special inauguration ceremony .”

"Please sit tight and hold on. Let's continue our dream journey of future transportation."

"This is the first thought about future transportation. Our personal jetpacks have already appeared. If such hubs can be built in major cities across the country, or even around the world, our jetpacks can realize global supply flights."

"Of course, due to the cost of personal jetpacks, it is still too difficult to popularize this method, so we have developed a large aircraft together with the Aviation Academy of China! A large aircraft that can be parked at an air transportation hub! A large aircraft that can carry 2000 passengers ! Meet people's travel needs."

"The shuttle machine under research is a fighter that can achieve Mach 5 supersonic cruise."

"A supersonic and high-load bomber that is still on paper. These are our research projects with the China Aviation Academy. During the research and development process, there will be many breakthroughs in science and technology."

"Similarly, we are also discussing the development plan of the sky train. The number of passengers can be greatly increased to meet the passenger demand."

Following Zhu Cheng's words, various aircraft sketches and formed art drawings with holographic projections kept flashing behind him.

The reporters seized the time and clicked to take pictures. This is tomorrow's headline news.And the scientists started pointing fingers at these drawings.The people in the mountain city are thinking about whether they can afford the price of traveling by large plane.

But you can imagine that kind of scene, where there are huge air transportation hubs floating above major cities, where personal jetpacks are docked, flying trains are docked, large planes are fully loaded with passengers, and they travel at supersonic speeds.

The scientists in the crowd naturally have experts in aerodynamics or aircraft design. This way of taking off and landing in the air is naturally more convenient and faster than the surface.

"This is to push aviation into the era of supersonic speed and the era of ultra-fast transit!"

"A lot of time is wasted in circling on landing and accelerating on takeoff."

"Not only that! This will also have a great impact and change in aircraft design. There may even be new aerodynamic formulas."

"A new era is coming soon? It's crazy."

……

Zhu Cheng didn't pay attention to the discussion in the audience. These are several projects he cooperated with the China Aviation Academy, the upgrade plan for large aircraft and fighter jets.This is a series of new aviation aircraft developed around Cree's air traffic hub.

The actual effect still depends on the usage of his transportation hub.It's just that now it's the performance time of the Cree Technology Center!
"The first product of the future transportation in our technology center is called: flying car."

When Zhu Cheng mentioned the flying car, the audience touched their wallets unconsciously. Is this the rhythm of buying their hands again?Cree products are of good quality and very functional.But prices have also soared along with availability.

The birth of any new thing requires a process of acceptance. When Karl Benz launched the Mercedes-Benz, he also faced the group of rich people.This is an important obstacle to transforming technology into economic benefits.How to effectively use technology is also an important task in scientific research.

"Flying cars, Henry Ford, the founder of the Ford Motor Company, once made bold predictions. With the development of technology, cars will fly one day sooner or later."

"In 1917, G. Curtis's first flying car made of aluminum hit the road. Although his car never flew, it just completed a short-distance flying jump. But such a brave attempt also made flying, walking On the research and development agenda."

"Telafga, a company located in Massachusetts, USA. Completed the first test flight of mankind's first flying folding car. The car can accommodate four people and has a pair of foldable wings."

"Today Cree's flying car is launched, named Walk!"

All the projections of the aircraft disappeared, and a projection of a car appeared. From the appearance, it looks like a space vehicle ahead of its time, with a streamlined design, a cockpit-style driver's seat, and two engines protruding from the rear of the aircraft.It is in line with the design style of the No. 10 warhead, and it will not be very difficult for the audience to accept.

"Compared with traditional flying cars, the engine of Cree's flying car uses a pulse detonation engine. This engine, when traveling in the city, has a huge The advantage is that it is more aerodynamic and maneuverable!"

“这辆车荷载4人，最大时速400千米。有一个100升的油箱，可以飞行5个小时！超过2000千米的航程！这就是我们的飞行汽车！空中漫步！”

Just when everyone thought the introduction of this car was coming here, they saw a fleet of flying cars appearing in the sky and flying towards the world science and technology center.
