The Imperial College campus covers a very large area. When this university was first built, Liu Jin was very generous and allocated a large piece of land to Imperial College.
In other aspects, Liu Jin has always been relatively picky. For example, in terms of his own food, clothing, housing and transportation, Liu Jin is casual after all. He does not pursue delicacies like other rich and powerful people.
Liu Jin, who came to the next life, knew very well that eating too much delicacies from mountains and seas is not necessarily a good thing. What matters when eating is nutritional balance, and ordinary vegetables and fruits are enough.
In terms of living and dressing, Liu Jin has always been relatively casual, and he has not deliberately talked about building a luxurious mansion or wearing nice clothes.
For Liu Jin, living comfortably and wearing comfortable clothes are more important than anything else.
In the eyes of rich and powerful people, Liu Jin is naturally a stingy and stingy person, but Liu Jin is very willing to invest in education and very willing to spend money.
Nowadays, the land in the southern district of Beijing is extremely expensive. It can be said that every inch of land is precious. But here in the new city of the southern district, Liu Jin has set aside a large amount of land to build a large number of universities. Each university has a large area, occupying
The land is vast.
If these lands were used to develop real estate, there would be no problem with just a few hundred million taels of silver. However, Liu Jin was using it to build a school, and he had no intention of parting with it.
Imperial College, which occupies a huge area, can be roughly divided into a front yard and a back yard. The front yard is the area where teaching buildings, dormitories, stadiums, canteens, libraries, etc. are located.
The backyard is the experimental site of Imperial College London. There are various laboratories and test sites here, which are specially used to conduct various experiments, so that the teachers and students of Imperial College can work hard.
At this moment, in the backyard, the school has specially built long concrete runways. At one end of the runway, many teachers and students gathered around an airplane, constantly having heated discussions.
Liu Jin's arrival did not attract anyone's attention. Everyone's attention was focused on the plane in front of them.
Liu Jin also immediately set his sights on this plane.
Compared with later aircraft, this aircraft is naturally very primitive. It uses a front propeller-powered aircraft and has a double-layer wing, which is obviously for the stability and safety of the wings.
There are three wheels in total at the front and back. The overall length is about six or seven meters. The long and narrow body looks a bit like a dragonfly.
Judging from the seat settings, this aircraft can carry two pilots at a time, with front and rear settings. However, it does not have the glass cover of later aircraft, but is directly exposed. This is in line with the design of early aircraft.
"It looks pretty good!"
Seeing such an airplane, Liu Jin laughed, and then knocked on the parts on the airplane, only to realize that many parts of the airplane were made of wood.
This also made Liu Jin couldn't help but feel a little embarrassed. How dare such a wooden aircraft fly into the sky?
Is this safe?
Will it fall apart by then?
Liu Jin was used to seeing jets and iron aircraft of later generations. To be honest, Liu Jin was really a little scared of this kind of screw machine and aircraft with wooden structure, and felt that it was unsafe.
"Feng Dan, Feng Shuang, can this plane you built fly into the sky?"
Liu Jin felt unsafe, but the other teachers and students next to him doubted whether the plane could fly up.
To be honest, for people in this period, everyone will indeed doubt whether the plane in front of them can fly into the sky. After all, the big guy in front of you, no matter how much it weighs, generally speaking, this
If you want to fly into the sky, you must have something light enough to fly up.
"Of course, there's absolutely no problem. I'll fly it to you later."
"Not only can it fly into the sky, but it can also fly very fast and very high."
Feng Dan said very confidently.
The Feng brothers, who are obsessed with flying into the sky, put all their energy into researching aircraft. They have experimented with the aircraft in front of them many times. This time, they were confident and prepared it in advance.
They have also undergone flight tests and flown in the sky once.
"Then fly quickly, this thing doesn't look like it can fly into the sky!"
"That's right. How heavy is this big thing? How does it fly into the sky?"
Others asked in confusion.
"hey-hey!"
"As you can see, the propeller in front is not there. We use a diesel engine to rotate this propeller. Through the rotation of the propeller, it can generate a thrust. When its thrust is strong enough, it can fly into the sky.
"
Feng Shuang pointed to the propeller in front and said.
"Then why do you want to build such a cement road?"
At this time, someone pointed to the track in front of them and asked.
"This is called the runway of an airplane. The airplane needs a certain amount of buffering when taking off and landing. It is safe to increase or decrease the speed. Otherwise, the airplane will fall down directly."
Feng Dan quickly explained.
"I see!"
Everyone nodded immediately. At this time, someone noticed Liu Jin and quickly saluted respectfully. When others saw it, they also quickly saluted.
"good!"
"Hello everyone!"
Liu Jin also smiled and greeted everyone, then came to Feng Dan and the Feng brothers, and said with a smile: "Not bad, not bad, it looks very good, a bit like a dragonfly."
"Liu Gong, when we originally designed it, we did refer to the structure of dragonflies. We found that dragonflies are the most powerful fliers in nature."
After hearing Liu Jin's words, brothers Feng Dan and Feng Shuang nodded repeatedly.
"Although dragonflies are very small and don't seem to fly very high, their flying ability is definitely a miracle of nature. It can not only hover in the air, but also fly upside down, and even fly 360 degrees
When flying in a high rotation, you can fly forward, backward, left, right, and in all directions very easily and smoothly.”
Everyone, please go and try it soon.]
"And according to our tests, the little dragonfly can also fly at high speeds of up to 50 kilometers per hour, and can continue to fly for several hours at a time."
"Such a powerful flying ability is something that no other natural animal has."
"So we were thinking about whether we could design an aircraft by referring to the structure of a dragonfly. But now what we can do is only simulate the shape and structure of the aircraft. There is no way to design the dragonfly's multiple wings for flexible flight."
"So far we have not been able to develop a wing that is as light, efficient, and flexible as a dragonfly's wings. There is no engine that can do this. We can only use a screw engine to power it."
Feng Dan explained his design inspiration in detail. His design inspiration came from natural insects such as dragonflies. By carefully observing the flying ability and structure of dragonflies, he finally designed the aircraft in front of him.
"I see. It seems that everything in nature is our best teacher."
After Liu Jin heard this, he smiled and nodded.
This is actually a bit similar to the bionic biology of later generations. In fact, most of the jet fighters of later generations imitate the appearance of powerful raptors flying at high speed.
Bionics has been widely used in later generations. Many of the equipment worn in the diving field are manufactured through bionics research.
"Yes, nature is full of countless mysteries, which are worthy of our serious research and study."
Feng Dan nodded solemnly.
"With our current technology, we are still unable to do many things. Compared with the creatures in nature, we are still very far away."
"Well, the reason why we humans can become more and more powerful is that we are good at learning, good at imitating, good at research, and constantly delving into, discovering, exploring new things, exploring the truths and laws of nature, and then Utilizing it will ultimately allow us humans to master more and more powerful power and make life better and better."
"If we are afraid of failure, afraid of exploration, afraid of new things, and our thoughts are bound and restricted, then we will never make any progress."
Liu Jin smiled and nodded, affirming Feng Dan and Feng Shuang.
In fact, science and technology itself originates from nature. It is the result of long-term understanding and summary of nature, continuous exploration of some of its laws, and then utilization of them, as well as continuous accumulation and progress.
Everyone listened to Liu Jin's words and kept nodding.
The biggest thing about new learning compared to old learning is that new learning is constantly researching and new things, and all kinds of new content, new knowledge, and new technologies are constantly emerging.
As for the old school, thousands of years have passed. People in the old school still hold those shabby books and memorize them by rote. They still have to read the mountains of annotations, generation after generation. People are glued to a few broken books, and generation after generation write notes that have been written badly by their predecessors.
The road became narrower and narrower, and gradually reached a dead end. It was like a pool of stagnant water that became more and more smelly. It had no vitality. It had not made any progress for thousands of years, and it just kept repeating the previous steps. The things that people repeat, their thoughts and concepts are tightly bound, and they have long since become something that hinders social progress and development.
New learning is different. There are many things to learn, and we are constantly exploring and researching new fields. New things are constantly emerging, and we are constantly improving and developing.
