Everyone saw the battle clearly, and the fierceness of the war appeared in front of everyone, and when the rockets hit Ron's face, they were surprised when they saw the intact glass surface!

Only 10 cm thick glass! What kind of concept is this to carry the attack of rockets! If this kind of composite armor is done in various combinations, how much of a role it will play on the battlefield!

"Of course, the melting point of glass is 600 to 1000 degrees, and adding metal materials to increase the melting point of the glass is also an important project for us in the future. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

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 if you want to use it on the battlefield, but the strong performance shown alone has made people watching the live broadcast feel its prospects.

"This glass is the main reason why we are the center of science and technology, the main reason why rotating buildings can fly, the density of glass is 2,200 kilograms to 2,800 kilograms per cubic meter, and steel is 7,850 kilograms per cubic meter! Even titanium alloy 4510 kg per cubic meter! Metallic glass has a very low density, but even more excellent performance, after foaming, it is even lighter! ”

"The entire building uses 20,000 cubic meters of metal glass, and the weight is only 40,000 tons, which ensures that our scientific and technological aircraft can take off perfectly!"

"Are you very curious, what principle is used when 40,000 tons of things fly? I'm going to show you. ”

Zhu Cheng said and took out a plate and a spinning top, these two things are props for him to demonstrate the principle, they can be seen everywhere on the market, and they are inexpensive. Called a magnetic levitation top toy, the disc is a permanent magnet, and there is also a permanent magnet underneath the top.

"When we rotate hard, this spinning top can float in the air, it doesn't somersault in the air, it doesn't run out, it's due to the conservation of angular momentum. According to Engshaw's law, any combination of electrostatic force, magnetostatic, and gravitational force cannot keep an object in a stable state, and all electrostatic fields, magnetostatic fields, and gravitational fields produce potential energy for a charged body or a magnet in the shape of a saddle. That is, with these three forces, a small magnet cannot be suspended in the air, and it will always slip away in a certain direction. ”

He demonstrated, and without spinning, the little spinning top was ejected off the disk without incident. This sheath-shaped potential energy does not make the object stable at all.

And the reason why this toy is balanced is to transform this saddle-shaped potential energy into a bowl-shaped potential energy. Let our tech center maintain a stable flight posture in this potential energy. And this potential energy transition, verified by Professor Michael Berry, is that this bowl-shaped potential well appears in a very small area above a magnet. ”

"For example, in our toys, the diameter of the magnet base is 6 centimeters, and this balance range is between 3 and 3.8 centimeters. Therefore, the weight of the hovering top must be adjusted just right to levitate in this zone. If it's too light or too heavy, the hovering top won't be able to balance in this zone and will fly out. ”

"The potential energy of this bowl shape is the key to our flight! Of course, the technology is very complex, and we have to overcome the effects of the Earth's rotation! Overcome the huge energy consumption! Overcome the force of the potential energy of the bowl type! ”

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

Of course, there is also the cable that he cooperated with the state to pull over, and this cable goes straight to the Panzhihua nuclear power plant! To this end, he also delivered a breeder reactor technology to the Panzhihua Power Plant.

There is also an isolated magnetic field, a huge magnetic field can distort a metal, and people who are under a strong magnetic field for a long time will also make biological secretion disorders, this kind of material that isolates the magnetic field is also a high-priced product. It was only by overcoming all kinds of difficulties that this flight center was completely flying.

"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 was small, but very penetrating. This kind of whispering is not without confidence, but everyone knows that his technology is already at the peak of the earth!

Cree has the strength to win the honor of the world's science and technology center!

Everyone watched in silence as the metal shell of the outer ring rotated, which was the source of power that could levitate. Glass structure, lightweight and more durable than metal,

This cross-century product appeared before 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 opened, and there are bigger surprises waiting for us later! This is a press conference about changing the way of travel, and this is a unique inauguration ceremony. ”

"Please sit still. We continue our dream journey of the future of mobility. ”

"This is the first thought about the future of transportation, our personal jetpacks have appeared, and if we can build such hubs in major cities across the country, and even around the world, our jetpacks can be realized, global supply flights."

"Of course, due to the cost of a personal jetpack, it is still too difficult for this method to be popularized, so we have developed a large aircraft together with AVIC Aviation Academy! A large plane that can dock at an air traffic hub! A large plane with a capacity of up to 2,000 passengers! Meet people's travel needs. ”

"The shuttle under development project is a fighter that can achieve Mach 5 supersonic cruise."

"A supersonic high-load bomber still on paper. These are all research projects between us and AVIC Academy. In the process of research and development, there will be many scientific and technological breakthroughs. ”

"Similarly, we are also discussing the development of the Skytrain. Greatly increase the number of passengers to meet the demand for passenger transport. ”

With Zhu Cheng's words, behind him, all kinds of aircraft sketches and shaped art drawings with holographic projections flashed continuously.

Reporters hurry up and take pictures, which are all tomorrow's headlines. And scientists began to point fingers at these drawings. The people of 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, with huge air traffic hubs floating over major cities, personal jetpacks parking, flying trains parking, large planes full of passengers, sailing at supersonic speeds.

The scientists in the crowd naturally have experts in aerodynamics or aircraft design, and 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 relay!"

"A lot of time is wasted when the plane hovers when it lands and accelerates when it takes off."

"It's not all! This will also have a big impact and change in aircraft design. It is even possible that a new aerodynamic formula will appear. ”

"Is a new era just around the corner? It's crazy. ”

……

Zhu Cheng ignored the discussion in the audience, which was a few projects he cooperated with the AVIC Aviation Institute, a large aircraft and fighter plane upgrade plan. This is a series of new aviation aircraft developed around Cree's air traffic hub.

The actual effect still depends on the use of his transportation hub. It's just that it's show time at the Career Technology Center!

"The first product of the future vehicle at our tech center is called: the flying car."

When Zhu Cheng said the flying car, the audience unconsciously touched their wallets, is this the rhythm of chopping hands? Cree's products are of good quality and very practical. But prices have also skyrocketed along with practicality.

The birth of any new thing requires a process of acceptance, and when Karl Benz launched the Mercedes-Benz car, he was also facing a group of rich people. This is a major obstacle to the difficulty of translating technology into economic benefits. How to make effective use of science and technology is also an important task in scientific research.

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

In 1917, G. Curtis's first flying car made of aluminum hit the road, although his car never flew, but only completed short flying jumps. But such a brave attempt also put the flight on the research and development agenda. ”

"Tyralgar, a company based in Massachusetts, USA. The first test flight of the first flying folding car of mankind was completed. The car seats four people and has a pair of foldable wings. ”

"Today Cree's flying car was launched, called Walk!"

The projection of all the planes disappeared to reveal the projection of a car, which from the outside looked like a space vehicle ahead of its time, with a streamlined design, cockpit-style cockpit, and two engines protruding from the rear of the aircraft. In line with the design style of the No. 10 warhead, it will not be very difficult for the audience to accept.

"Compared with traditional flying cars, the engine of our Cree flying car uses a pulse detonation engine, which has a huge advantage over traditional turbofan, turbine and propeller aircraft when traveling through the city, that is, it is more aerodynamic and maneuverable!"

"The car has a capacity of four people and a maximum speed of 400 kilometers per hour. There is a 100-liter fuel tank for 5 hours of flight! More than 2,000 km range! This is our flying car! Skywalk! ”

Just when everyone thought that the introduction of this car was about to come here, they saw the convoy of flying cars appearing in the sky and flying towards the world's science and technology center. (To be continued.) )
