"Tear!"
With the ear-piercing sound of tearing tape, the five-meter-long red seal separated from the box and was thrown away by Chen Yu at an altitude of 3,400 meters.
In order to allow the audience to see clearly, he specifically turned sideways, stood on the left side of the express box, faced the camera and slowly opened the left box lid, revealing the light blue cylinder inside.
Then, Chen Yu walked to the right side and opened the lid of the right box. The complete picture of the product was finally revealed to Chen Yu and more than 20 million viewers...
[Nima! barrel?]
[This cannon barrel is not very smart.]
[It’s a bit like Dongfeng Express!]
[Maybe it's a nuclear bomb launch pad.]
[Electromagnetic gun stone hammer! Summon Miss Gun!]
[Obviously it’s a planetary engine... ]
[Up master, no matter how awesome you are, do you dare to live broadcast in the Forbidden City on Monday?]
"Um… "
Taking four or five steps back, Chen Yu carefully observed the shape of the blue cylinder, frowning and thinking.
Like many viewers, he couldn't recognize what this thing was even if he was present at the scene.
"Here, help."
They hooked their hands at Xiao Taohong, and the two completely separated the express box from the product.
"Huh..."
Throwing the box away, Chen Yu controlled the camera to observe the cylinder 360 degrees, but still couldn't determine its true use.
"After the unboxing process, everyone must be like me, confused about what it is. From the portal, to the weather control console, to the floating castle, it is true that the more futuristic the product is, the more it exceeds our imagination. "
Reaching out, Chen Yu took out a card from the bayonet on the right side of the cylinder: "But fortunately, with the help of the manual, we, the 'ignorant' ancients, can explore the mystery of the future."
With that said, Chen Yu skillfully activated the card switch and began to read carefully.
"What the hell?"
As soon as he saw the name of the product, Chen Yu couldn't help but exclaimed and quickly accelerated his reading speed. As the understanding gradually deepened, the surprise immediately turned from shock to admiration... and he kept mumbling to himself.
"magic… "
"It's so beautiful..."
“Unbelievable…”
"Amazing!"
Since this card did not have projection capabilities, only Chen Yu could see the content and explanations. The 20 million viewers in the live broadcast room were itching to wait, but they could only wait anxiously and send out urging barrages.
After more than ten minutes of "silence", Chen Yu put down the card, looked at the camera and was silent for a long time, and finally sighed: "It's amazing, it takes so many willful designers to create this kind of product."
"Does anyone know what it is used for?"
[you do not say! How the hell do we know? !]
[Made! The anchor definitely did it on purpose!]
[The cameraman has a lot of shit today.]
[This damn program effect! Stop being so pretentious!]
[I don’t know what you are talking about. I just came to see the female assistant.]
[Looking at the female assistant as well. Can a discussion be so exciting with just a big iron rod? What a bunch of fagots!]
[I watched it in every live broadcast room, with a total of more than 20 million viewers! Don’t you all have to go to school and work?]
Insert the instruction manual back into the bayonet, Chen Yu stroked the smooth surface of the cylinder a few times, sorted out his words for a while, and said: "This product is difficult to explain in one or two sentences. Because it involves many things related to astronomy, chemistry, physics, Knowledge of aviation and aerospace.”
"Yes, this is an aerospace product. A product that no one has thought about in 2020. All previous technologies, even if they cannot be made in modern times, have had scientists, novelists, or various cultures It has been described in the work. Different technologies also have theoretical support."
"But it." Chen Yu patted the cylinder: "It is blank in human history. At least, I haven't heard of anyone or any cultural work that has its shadow."
After a slight pause, Chen Yu straightened his back, recalling the knowledge he had learned over the past few weeks in his mind, and said loudly: "The unboxing process is over, and now comes the introduction. I will try my best to use concise language to introduce this product to you. The magic and absurdity.”
"First of all, if humans want to enter space, there are currently only two ways."
"First, rocket propulsion. Second, aviation aircraft. The latter also requires rocket propulsion. So strictly speaking, the only way for humans to enter space is rocket propulsion."
"But due to the high cost of rocket propulsion, the scientific community has always wanted to find a more efficient method. The most famous and feasible one is the space elevator."
As he spoke, Chen Yu stretched out a finger: "In order to introduce the space elevator, I have to mention a character. Tsiolkovsky of Mao. The audience in the live broadcast room may not know this name. But he You must have heard of the title.”
"He is revered as the father of aerospace!"
"That sentence: The earth is the cradle of mankind, but mankind will not stay in the cradle forever. This is what this great god said."
"This deaf god was born in 1857, a time when there were no airplanes. But at that time, before humans had yet studied how to get into the sky, he began to study how to get into the sky, how to fly into space, and how to enter the universe."
"He saw that a punctured balloon would be blown by the air flow, understood the reaction force, immediately created the principle of jet rockets, and completed the formulas and calculations of the system. One of the formulas was also named after him, called Ciocco Fitz formula.”
"V=V0×Ln(m0/m1)."
"The derivation of the rocket speed formula is very easy and can be calculated with a little calculus. I will not delay on such a simple problem."
[ah! It's the boss! my eyes!]
[show!]
[I feel the ridicule from the wise.]
[My mother asked me why I jumped into the toilet to watch the video...]
[Liberal arts students say you have grammatical errors. (Smile)]
Adjusting the mask, Chen Yu continued: "According to the formula, if you want to go to the sky, the jet speed must be high, so the mass ratio of m0/m1 must also be large. m0 is the original mass of the rocket, and m1 is the remaining mass after the jet. Both. The 'ratio' between them is larger, what does it mean?"
[have no idea.]
[I don’t know +1.]
[I can understand every sentence, but I can’t understand it at all.]
[I understand it all, but I don’t understand it at all...]
[Awesome, awesome...]
After a pause, Chen Yu smiled: "It means that the mass of the fuel is greater. Therefore, most of the mass of the rocket is fuel. This has not changed until now. This is also the main reason for the high cost of space operations. It is too wasteful. "
"After completing the principle of jet rockets, this god went a step further and specified liquid fuel, and then created the principle of multi-stage rockets... Until he completed this series of great achievements, humans did not even know how to build airplanes."
"Some viewers may want to ask, what is his relationship with the sky elevator? Why focus on introducing him?"
"Because this god also proposed the space elevator and completed all the theories and calculations, including the structural strength of the material, the height of the space elevator, the weight ratio, the 36,000-kilometer balance point, etc. As long as the materials in it meet the standards, Humanity can take advantage of the legacy of the father of aerospace and directly build a space elevator."
"This is not a delusion! In 2019, Japan and China have successively produced qualified materials and have begun a space elevator construction plan. The project will be fully launched by 2050 at the most, and it will definitely be seen in everyone's lifetime."
"but… "
Chen Yu stretched out his hand and patted the surface of the cylinder: "With this thing, the space elevator project can be abandoned. It doesn't need to be 2050. With humanity's current technology, there is a basis for building this product."
"The only thing that limits the time of its birth is the imagination of the scientific community."
"Its name is..."
"The earth sprays water!"
