Daming Town Haiwang

Chapter 2150, the great man who wants to fly in the sky

Seeing the heater, Liu Jin hurried over. Many students had already gathered around the scene. Everyone was excitedly looking at the big ball in the sky and the two people in the basket.

There is also a long rope tied to a big tree that has been lowered from the big heater, apparently also to prevent it from flying too far and not being able to return.

"It really flew, it's incredible!"

"Isn't it? When Feng Shuang and Feng Dan said they saw the Kongming Lantern, they were inspired and thought that if the Kongming Lantern was big enough, they would be able to take people to the sky. I didn't expect it to be true succeeded."

"This is the graduation project of the two brothers. It's amazing. They can really fly to the sky. I don't know what it feels like to see the ground from the sky."

"The two brothers were clamoring that they wanted to fly into the sky. I still didn't believe it. I didn't expect them to be able to do it. Does anyone know the reason for 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 it, he immediately touched his chin and said.

"It's such a simple truth, why didn't I think of it."

Some people couldn't help but slapped their thighs fiercely when they heard it.

They all understand and have learned the basic physics knowledge, but when it comes to applying it, many people are at a loss and don't know how to better apply what they have learned.

"If the density decreases to generate buoyancy, can we use a lighter gas to make a larger balloon? We are now studying air. The lightest gas in the air, hydrogen, can also generate buoyancy. up to the sky."

Then there was a classmate who was studying chemistry next to him, who thought for a while and said.

"Yeah, using a lighter gas can also generate buoyancy, and it can also lift people into the sky."

"Classmate, what's your name?"

"I'm Li Chaoying from the School of Physics. How about we work together to design a hydrogen-filled balloon and see if it can rise into the sky like a hot air balloon?"

"My name is Zheng Mingxuan, and I'm from the School of Chemistry. If you're interested, we can work together."

"Although it is feasible for you to use the low air density to generate buoyancy to ascend to the sky, it is obviously very difficult to control the speed and direction. Where did it blow to?"

"Is there any other way to get us up into the sky?"

A classmate next to him frowned and thought about it.

The Royal Institute of Technology of Ming Dynasty puts great emphasis on the spirit of exploration. Now seeing someone ascending to the sky, other students are also discussing whether there are other ways to make people 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 the students of later generations, the students of this period cherish the learning opportunities more.

Especially for ordinary children, their parents are often poorly educated, and they were farmers in their era. It is hard for them to learn new things. Naturally, they attach great importance to and devote themselves to reading.

Since ancient times, being able to acquire knowledge and skills has been something that countless people have dreamed of. You must know that before learning to blacksmith, you had to work for the master for free for several years.

In an era when skills and knowledge were not easily passed on, reading was an extremely luxurious thing.

Therefore, whether it is the parents at home or the teachers in the school, they are extremely strict in teaching, and eating a ruler is a common thing.

Growing up in such an environment, a new generation of Daming people are extremely serious about reading and learning, and those who can come to the Royal Institute of Technology of Ming Dynasty to study further will cherish this opportunity very much.

According to Liu Jin's requirements, the university system of the Ming Dynasty imitated the university system of European and American countries in later generations. Unable to graduate.

It definitely doesn't mean to let you come here to eat and wait to die to raise pigs.

Although Liu Jin is rich, he would never say that he came to raise pigs when he was rich.

What's more, these students in colleges and universities also have to pay a large amount of tuition fees every year. This tuition fee is more than ten taels of silver a year, which is equivalent to the annual income of a Ming Dynasty.

Parents spend money to send you in, definitely not to let you eat, drink and have fun here, but to hope that you will succeed in your studies. This graduate from the Royal Institute of Technology of Ming Dynasty is the talent that major factories and commercial firms 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 that the hot air balloon was flying higher and higher, and the ropes tied to it had reached the bottom, the students on the ground also shouted one after another.

"Wait a minute, let me take a closer look at the scenery in front of me."

Inside the basket of the hot air balloon, Feng Shuang shouted excitedly.

Standing high and looking far away, at this moment at a height of [-] meters, you can clearly see the situation in the capital. It is very spectacular and a completely different scenery.

Straight roads built one after another, criss-crossing, extending in all directions, high-rise buildings everywhere, a beautiful campus, and the situation of the school next door, etc. can be seen in a panoramic view.

The cars on the mainland outside the school have become very small at this moment, the traffic is busy, and it is extremely lively.

"Pull us down!"

After watching for more than ten minutes, the two brothers decided to go on.

Soon, the students on the ground began to work hard together.

"Hey, hey!"

"La ah, la ah!"

With many students pulling the rope vigorously, they pulled down the hot air balloon little by little, and the huge hot air balloon gradually landed.

When they got to the ground, before the two brothers Feng Shuang and Feng Dan got down, many students rushed over at once.

"I'll try first, I'll try 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 turns slowly, take turns."

Soon, two people were replaced again, and at the same time it started to burn again, and the hot air balloon lifted off slowly again, leaving many students on the ground watching eagerly, looking forward to the feeling of being able to sit on the hot air balloon to see .

"Feng Shuang, Feng Dan!"

"How's the view up there?"

"Haha, of course it's very beautiful."

"It is a completely different feeling to look down on the whole land from a high altitude. It is very spectacular to be able to see far away. We can almost have a panoramic view of the entire southern district."

"Unfortunately, there are still many restrictions on this hot air balloon. If a machine can be invented that allows people to fly into the sky, control and fly freely, that would be amazing."

Feng Dan was thinking while thinking.

"Can you use a propeller to fly into the sky?"

At this moment, Liu Jin, who had not spoken all this time, answered.

"propeller?"

When everyone heard this, they looked at Liu Jin in unison. They saw that Liu Jin had an extraordinary demeanor. He looked like a teacher in the school. These students also saluted respectfully in unison.

Liu Jin also greeted everyone with a smile.

"Sir, how can this propeller fly?"

Feng Shuang thought for a while and asked.

"Yeah, choose, isn't this propeller used on boats to propel the boat forward?"

Feng Dan also followed suit.

"Forehead"

When Liu Jin was asked, he didn't know how to answer it.

After thinking for a while, he said, "I just looked at this hot air balloon and thought it was slow and difficult to control its direction."

"So I thought, if a machine is used to provide power, such as an internal combustion engine, and a device similar to a dragonfly's wings is used, can a machine that can fly in the sky be created."

"Mr.'s idea is very bold and innovative, and it seems feasible."

When Feng Shuang heard this, he immediately touched his chin and began to think carefully.

"I've been researching this thing, and want to create a machine that can fly in the sky."

"This idea may really work, you can try it."

"I also think there are still many possibilities for this idea."

"We all played with bamboo dragonflies when we were young. The principle of this bamboo dragonfly feels very similar to this. When the bamboo dragonfly rotates fast enough, it can fly into the sky."

"If we use a powerful enough internal combustion engine to make blades similar to bamboo dragonflies, and then as long as the speed is fast enough, I think it can definitely rise to the sky."

"This seems to be really possible. Is there anyone who came to study this together?"

"Me, count me in. I am studying mechanical engineering. My name is Chen Tianyu."

"Count me in, count me in. I major in internal combustion engines, specializing in the manufacture of internal combustion engines. My name is Sun Wei!"

"Count me in. My family has a machinery factory. If you need to process any parts, you can go directly to my factory to process them."

"Count me in, count me in. My family still has a little money. If I need funds, I can take out a few thousand taels of silver or something."

Listening to their words, Liu Jin on the side couldn't help being slightly dumbfounded.

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 mean the bamboo dragonfly. The bamboo dragonfly is a bit like a helicopter.

Also, some of these students' home conditions are expected to be good, and they are siege and rich. You don't go to learn the old ones, but come to learn the new ones.
