Chapter 2151: A great man who wants to fly in the sky

Previous page        Return to Catalog        Next page

    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 large 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 flying, it¡¯s incredible!¡±

    "Isn't that right? When brothers Feng Shuang and Feng Dan said they saw the Kongming Lantern, they were inspired and thought that if the Kongming Lantern was big enough, it would definitely be able to take 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. Does any classmate know the principle of 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 to produce 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, making people  Up in the sky.¡±

    ? Then there was a classmate studying chemistry next to me, who thought about it and said.

    "Yes, using lighter gas can also produce 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 there is a strong wind, you will not 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 him frowned and started thinking.

    Daming 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 after hearing their discussion.

    ¡°My money is not in vain, the students in this college are quite good.

    ?Compared to 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. It is not easy to find new schools to study. Naturally, they attach great importance to and pay attention to reading.

    Since ancient times, being able to learn knowledge and skills has been something that countless people have dreamed of. 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 are not easily passed on from person to person, studying is 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 have a ruler.

    The new generation of Ming people who grew up in such an environment are extremely serious about reading and learning. If they can come to the Ming Dynasty Royal Institute of Technology to study, they 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  You can't graduate.

    ???????????????????????????????????????????????????????????????????????

    Although Liu Jin is rich, he will never say that he has money to raise pigs.

    What¡¯s more, these students in colleges and universities have the same number of students every year.??Much like 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 can definitely rise into the sky."

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

    ¡°Me, count me in, I major 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 are these students so awesome?

    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.

    ??????????????? Some of these students¡¯ families are actually in pretty good condition, they¡¯re attacking cities and they¡¯re rich, but instead of learning the old stuff, you¡¯re here to learn the new stuff.  (Remember the website address: www.hlnovel.com
