Chapter 2151, the great man who wants to fly in the sky
Seeing the heater, Liu Jin hurried over. Many students had gathered at the scene. Everyone was excitedly looking at the big ball in the sky and the two people in the basket.
The big heater also has a long rope tied to a big tree that is lowered down. This is obviously to prevent it from flying too far and unable to come back.
"It's really incredible to fly!"
"Isn't that right? When brothers Feng Shuang and Feng Shan said they saw the Kongming Lantern, they were inspired. They thought that if the Kongming Lantern was big enough, it would be able to bring people to the sky. Unexpectedly, it actually happened.
It was successful."
"This is the graduation project of the two brothers. It's amazing. It can really fly into the sky. I don't know what it feels like to see the ground from the sky."
"The two brothers were clamoring to fly in the sky. I didn't believe it. I didn't expect them to actually be able to do it. Is there any classmate who knows the principle behind this?"
"The principle is actually very simple, that is, the air will expand and become less dense after being heated, so as long as there is a large enough balloon and the air inside the balloon is continuously heated, the balloon can generate enough buoyancy to rise into the sky."
When someone heard this, they immediately touched their chin and said.
"What a simple truth, why didn't I think of it?"
Some people couldn't help but slap their thighs when they heard it.
They all know and have learned basic physics knowledge, but when it comes to applying it, many people are confused and don't know how to better apply what they have learned.
"If the density decreases and produces buoyancy, can we use a lighter mass of gas to make a larger balloon? We are now studying air. Hydrogen, the lightest gas in the air, can also produce buoyancy, which makes people
Rise up into the sky."
Then there was a classmate studying chemistry next to me, who thought about it and said.
"Yes, using lighter gas can also create buoyancy and allow people to rise into the sky."
"Classmate, what's your name?"
"I am Li Chaoying from the School of Physics. How about we work together to design a large balloon filled with hydrogen and see if it can rise into the sky like a hot air balloon?"
"My name is Zheng Mingxuan, from the School of Chemistry. If you are interested, we can work together."
"Although your method of using the low density of air to generate buoyancy to rise into the sky is feasible, the speed and direction are obviously very difficult to control. If you encounter strong winds, you won't know what will happen if you blow it casually.
Where did it blow?"
"Is there any other way that we can get into the sky?"
A classmate next to me frowned and started thinking.
The Ming Dynasty Royal Institute of Technology places great emphasis on the spirit of exploration. Now that they see someone ascending to the sky, other students are also discussing whether there are other ways to allow people to ascend to the sky.
Liu Jin on the side listened carefully and smiled when he heard their discussion.
My money is not in vain, the students in this college are quite good...
Compared with students of later generations, students of this period cherish learning opportunities more.
Especially for ordinary children, their parents are often uneducated and they were farmers at that time. It is not easy for them to have new learning to learn. Naturally, they attach great importance to and pay attention to reading.
Since ancient times, being able to learn knowledge and skills has been the dream of countless people. You must know that in the past, to learn blacksmithing, you had to work for free for several years.
In an era when skills and knowledge were not easily passed down from person to person, studying was an extremely luxurious thing.
Therefore, whether it is parents at home or teachers at school, they are extremely strict in teaching, and it is common to miss the ruler.
The new generation of Ming people who grew up in such an environment are extremely serious about reading and learning. If they can go to the Ming Royal Institute of Technology to study, it will be even more important.
I cherish this opportunity very much.
According to Liu Jin's request, the university system of the Ming Dynasty imitated the university system of later European and American countries. It emphasized strict entry and strict exit. The top students who come in are selected from a million. The same is also very strict when they go out. If you don't meet the requirements, you will be a loser. Those who cannot graduate.
I'm definitely not asking you to come and eat and raise pigs until they die.
Although Liu Jin is rich, he would never say that he would raise pigs if he had money.
What's more, these students in colleges and universities also have to pay a hefty tuition fee every year. This tuition fee costs more than ten taels of silver a year, which is equivalent to the annual income of a Ming Dynasty person.
When your parents spend money to send you here, they definitely don’t want you to eat, drink and have fun here, but they want you to succeed in your studies. Graduates from the Ming Dynasty Royal Institute of Technology are the talents that major factories and businesses are vying for. The income is extremely high.
"The rope is at the end. This is more than 100 meters of rope!"
"Feng Shuang, Feng Dan, do you want to pull you down?"
Seeing the hot air balloon flying higher and higher, the ropes that tied it were all the way to the bottom, and the students on the ground also shouted one after another.
"Wait a moment, let me take a closer look at the scenery in front of me."
Inside the basket of the hot air balloon, Feng Shuang started shouting excitedly.
Standing high and looking far away, at this moment at a height of 100 meters, you can clearly see the situation in the capital. It is very spectacular and a completely different scenery.
The straight roads built one after another crisscross and extend in all directions. You can have a panoramic view of high-rise buildings, beautiful campuses, and the situation of the school next door.
The cars on the mainland outside the school have become very small at this moment, and the traffic is busy and very lively.
"Pull us down!"
After watching for more than ten minutes, the two brothers decided to go.
Soon, the students on the ground began to work hard together.
"Hey, hey!"
"Laah, laah!"
As many students pulled the rope hard and pulled the hot air balloon down little by little, the huge hot air balloon gradually landed.
When they reached the ground, before the two brothers Feng Shuang and Feng Dan came down, many classmates swarmed over.
"I'll try it first, I'll try it first!"
"I'll come first, I'll come first."
"I didn't say it just now, let me try it later,"….
"Everyone, stop arguing, take your turn, take your turn."
Soon, two people were replaced again, and it started to burn again. The hot air balloon slowly lifted into the sky again, leaving many students on the ground looking at it eagerly, looking forward to the feeling of being able to sit up in the hot air balloon and take a look. .
"Feng Shuang, Feng Dan!"
"What's the view like up there?"
"Haha, of course it's very beautiful."
"It's a completely different feeling to overlook the entire land from a high altitude. You can see very far away. We can almost have a panoramic view of the entire southern district. It's very spectacular."
"It's a pity that there are still many restrictions on this hot air balloon. It would be awesome if we could invent a machine that allows people to fly into the sky and control and fly freely."
Feng Dan was thinking about it.
"You can use propellers to fly in the sky."
At this time, Liu Jin, who had been silent for a long time, answered.
"propeller?"
Upon hearing this, everyone looked at Liu Jin and saw that Liu Jin had an extraordinary bearing and looked like a teacher in the school. The students also respectfully bowed to him.
Liu Jin also smiled and returned the greetings to everyone.
"Sir, how can this propeller fly?"
Feng Shuang thought for a while and asked.
"Yes, choose, isn't this propeller used on ships to push the ship forward?"
Feng Dan also followed suit.
"Forehead..."
Liu Jin was asked and didn't know how to answer for a moment.
After thinking for a while, he said: "I just looked at this hot air balloon and thought it was slow and difficult to control the direction."
"So I thought, if we use machines to provide power, such as using an internal combustion engine to provide power, and drive a device similar to dragonfly wings, can we create a machine that can fly in the sky."
"Sir's idea is very bold and innovative. It seems feasible."
When Feng Shuang heard this, he immediately touched his chin and began to think carefully.
"I have been studying this thing for a long time. I want to build a machine that can fly in the sky."
"This idea might actually work, you can give it a try."
"I also think this idea still has a lot of feasibility."
"We all played with bamboo dragonflies when we were kids. The principle of this bamboo dragonfly feels very similar to this. When the bamboo dragonfly spins fast enough, it can fly into the sky."
"If we use a powerful enough internal combustion engine to make blades similar to those of a bamboo dragonfly, and then as long as the speed is fast enough, I think it will definitely be able to rise into the sky."
"This seems to be really possible. Have you studied this together?"
"Me, count me in, I majored in mechanical engineering, my name is Chen Tianyu."
"Count me in, count me in, I major in internal combustion engines and specialize in manufacturing internal combustion engines. My name is Sun Wei!"
"Count me in. I have a machinery factory at home. If you need to process any parts, you can go directly to my factory for processing."
"Count me in, count me in, my family still has a little money. If I need funds, I can get it, a few thousand taels of silver or something."
Liu Jin on the side couldn't help being slightly dumbfounded as he listened to their words.
How awesome are these students?
I just mentioned it, and they immediately thought of going to the bamboo dragonfly. The key is that I didn't actually mean the bamboo dragonfly. The bamboo dragonfly is a bit like a helicopter.
Also, some of these students' families are actually in good condition, they are attacking the city and they are rich. Instead of learning the old learning, you come here to learn the new learning...
