"I'm Zhu Cheng of Cree, a few days ago, Cree's new professional manager, launched a self-driving car, positioning 2 million mid-level autonomous vehicles, this is a mid-range positioning vehicle, so what is our high-end positioning model?"

"Our high-end positioning model is not a luxury version of a self-driving car, but Cree's latest achievement, the personal jetpack. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info his safety, at the inauguration ceremony, everyone saw that during this time, whether it was WRC or Cree's press conference, I didn't attend because I was overcoming the technical difficulties of the jetpack. ”

"The breakthrough of various technical problems has officially brought the jetpack to the public!"

Zhu Cheng pointed to the metallic launch compartment behind him and continued: "The first difficulty of the jetpack is his take-off. ”

"It's no secret that on land, there are long runways that allow planes to accelerate."

"The side of the wing is a shape in which the upper edge is arched upwards and the lower edge is basically straight, and according to Bernoulli's equation, the atmospheric pressure on the upper surface of the wing is smaller than that on the lower surface, so that the lift force is generated, and the aircraft can lift off the ground when the lift force reaches a certain level."

"And on aircraft carriers, steam catapults can be used."

"The method of take-off is being explored by all countries, especially vertical take-off and landing, which has achieved preliminary results, and this launch pad is our latest achievement of Cree, electromagnetic catapult!"

After Zhu Cheng said this, he knew that this technology would definitely be targeted by the military, because this technology was just needed.

As long as the winged aircraft does not exceed Mach 1, the Bernoulli equation can basically be used to design the wing, but the high-speed flight of Mach 2 or 3 like a fighter is not good, if the speed is too large, the air on the surface of the wing will become viscous, and the Reynolds number should be taken into account, and there will be another formula at that time.

At this time, the wing is different from the ordinary wing, how to take off is a key research topic of high-speed cruise fighters, fuel saving means the expansion of the combat radius.

"Of course, our catapults are only there to increase the range when we are out of the road. In an ordinary environment, the engine of our personal jetpack will be transformed into a second working mode, rocket propulsion mode, which can achieve fast vertical take-off and landing. It's just that just like the disadvantages of vertical take-off and landing, the fuel consumption is larger. ”

"Our fuel uses liquid hydrogen and liquid oxygen fuel packs, and a fuel pack can be used for about 400km, a number that depends on many factors such as lifting mode, wind resistance, etc. Of course, if you run out of fuel, our Daystar will also remind you to remember to change the fuel pack. ”

"Let's move on to the first-person flight live!"

The barrage on the live broadcast platform is swiping.

"Cree has a lot of technology lately, and I feel like my pockets are going to be emptied."

"In the first few months, I was excited when I went to a Cree conference. Now as soon as Cree opens the conference, I am scared. There are so many products, I want to buy them! ”

"In the past, I persuaded my daughter-in-law not to add a shopping cart, but now my daughter-in-law advises me not to watch the Cree press conference."

"It's actually a live flight! I gave 99 points for this wave, and the remaining one point was sent to Lao Zhu in the form of an order. ”

"This is the rhythm of heaven!"

"I can't understand the world more and more, the routines in the city are deep, I want to go back to the countryside!"

"Flight live?"

……

With the barrage, Zhu Cheng adjusted the jetpack, covered with silver-white metal, and he walked into the ejection chamber. Holographic screens appeared, and rows of data appeared in front of the public. This is the camera switching to Zhu Cheng's first point of view.

"Cree's personal jetpack can be used without professional flying experience or a pilot's license! Because of all this, there is an automatic driving system to escort. It's a fool's errand! One-click start. ”

He lightly clicked the button of the launch compartment, and Zhu Cheng's whole person was ejected into the air, and the wings of the air pack were extended, the pulse detonation engine started, and a small sound sounded.

"Extreme silence! is our pursuit. The biggest defect of the detonation engine, the destruction of machinery and human body by loud noise, has been overcome by Cree. ”

The flight altitude is constantly raised, slowly leveling with the Gemini building, in front of the Gemini building, constantly circling, the first perspective, the scene on the ground, to everyone.

With an acceleration, Zhu Cheng rushed towards the huge statue in the central square of Shancheng City, the tail of which was left in the air, which was the product of liquid hydrogen and liquid oxygen fuel packets Water molecules.

"No pollution! Protecting the environment. Reducing pollution will benefit generations to come! Clean and efficient energy has always been my pursuit. ”

The sun has set in the west, paving the whole mountain city with golden yellow, and the city at this time is the most noisy time, people who get off work crowd the bus at the bus stop, and the road is full of vehicles, and the city is complicated and orderly. The rivers are staggered, the cars on the ring road are circulating back and forth, heading out of the city, and there are some big mountains in the distance, and the shadows are not clear.

"Soar freely above the blue sky! This is the dream of mankind all along! Since ancient times, human beings have dreamed of soaring in the sky like birds, kites more than 2,000 years ago, the myth of Chang'e running to the moon, and the fantasy of soaring clouds and fog. At the end of the 14th century, the Ming Dynasty's scholars and doctors made 47 rockets and firecrackers, tied them to chairs, and rushed into the blue sky. It's a pity that the explosion took his life. ”

"Before 1900, all objects that were considered heavier than air could not reach the blue sky. There is a team of American brothers, who have made outstanding contributions to the history of world flight, and after more than 1,000 gliding test flights, in 1903, Aviator 1 was born. ”

"In 1930, piston-driven propeller aircraft reached a maximum speed of 700 kilometers per hour, and the dive was close to the speed of sound. In 1934, Aoan obtained a patent for a centrifugal turbojet engine. On August 27, 1939, Auan used his engine to build the HE-178 jet. ”

"In 1947, humanity finally broke through the sound barrier! Completed a supersonic flight. ”

"So far, human rockets have rushed out of the atmosphere with satellites, American F22 fighter jets can cruise at supersonic speeds, and helicopters have been used for disaster relief. Drones are also beginning to be used in various fields. Civil aircraft are getting bigger and bigger. With the rapid development of science and technology, we have realized that we have flown into the blue sky! But is the dream really coming true? ”

"Sitting in a small iron box, is it a dream come true? Not! ”

"We can't touch the clouds, we're afraid of thunderstorms, we're not free. Therefore, we at Cree today took out the product of our personal jetpack, and truly soared freely above the blue sky! ”

As soon as Zhu Cheng's words fell, he accelerated, rushed to the clouds in the sky, and turned around twice before leaving. And the people in the central square of the mountain city all craned their necks and took out their mobile phones to take pictures of the genius who wantonly indulged his talent in the sky!

Pedestrians naturally know what this is, as a mountain city person, they don't know the name of their parents' officials, but this company is remembered and impressed by the mountain city people.

"I have to say that I have a strong desire to buy Cree's products, so it depends on the price."

"Looking at the positioning is not like a product that ordinary people can accept, let's just take a look."

"Looking back at Cree's smart eye, I think this price will eventually come down."

"We still have to listen to what Zhu Cheng has to say, after all, Cree is his master. But I believe him! ”

"Believe in plus one!"

"Look at my space, there is a small video of hey, hey, hey!"

……

"The cost of memory metal and nitinol of this product is very high, and the price of the personal jetpack is currently positioned as a high-end customer group, and the price is relatively expensive, with the initial pricing of the luxury version of the price of 10 million yuan, while the price of the ordinary version is 5 million yuan."

"This price is just the price of the jetpack, and the price of the liquid hydrogen and liquid oxygen fuel pack is calculated separately, so this is a luxury item. When you buy, you can properly consider your spending power. I will also mount the relevant price list on Cree's official website at a later date for your reference. ”

"So let's enjoy this feeling of being free to soar into the blue sky and look down on the earth." He continued to soar over the mountain city, and the live broadcast continued, detonating waves of barrage and applause.

And in Silicon Valley in the United States, next to Mountain View is the Rocky Mountains, where Google X Labs is hidden, and Silva stopped what he was doing and glanced up at the time. X Lab is located 200 meters underground

Google's X Research Lab is rumored to be located in a two-story red-brick building half a mile from Google's headquarters in Mountain View.

However, the real experimental center is located underground, and when Page was established, it was modeled after the practice of a great man in the East when he established the "third-line" military industry, and set up a laboratory in the mountains.

Silva was 200 meters in the middle of the mountain, and he stopped what he was doing because he had something big to do.

The artificial intelligence built in cooperation with the US Department of Defense is in this laboratory, physically isolated, 200 meters underground, and the BLU-113, the world's most advanced conventional ground-penetrating missile, can only penetrate 30 meters of soft soil. 200-meter mountain structures, in theory, are not afraid of any conventional blows.

"Lord, report on the progress of the matrix now."

"Mr. Silva, Matrix, the main program of Project Matrix has been completely built, relying on Google's Android vulnerability and Google's huge search engine users, the control system of our Project Matrix Lord has completed the evolution, and the complete assembly has been established. The associated network communication arteries have met the most basic needs of the matrix plan. The relevant circulatory system of life has passed experiments. The Matrix program can be launched! ”
