Kang Yun couldn't pull out his eyes when he saw this, he couldn't get anything on the stage, so he had good eyesight, and at this moment, he saw Zhou Cheng engrossed in writing and painting, and asked in a low voice. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Mr. Zhou, what are you drawing, you want to jump off the building? Why does this person still have wings on his back?"

"Jumping off the building, what's the situation, I'll see!"

As soon as Wang Gang heard that he jumped off the building, he got up from the sofa with a grunt, looked around, couldn't help grinning, pointed to the image on the paper and said with a smile.

"Mr. Zhou, you are drawing wings, why are you so small, this is simply ......"

"The bigger the wings, the greater the resistance...... I think the wings are a little smaller...... Wait, or maybe you don't have wings?"

"Wouldn't you fall to your death if you didn't need to......"

Wang Gang smiled, but Zhou Cheng frowned and modified, after a long time, it seemed that he was very busy, and he pressed it on his mobile phone, but he turned his head to Kang Yun and asked.

"Xiaoyun, this drone is yours?"

If you want to talk about the Chinese writing culture, it is really broad and profound, especially Kang Yun, although he is a child on weekdays, but he is no less accomplished than others in this area.

There are too many things that can be seen at a glance by other people's names.

For example, unfamiliar people call him Kang Yun, family members call him Ah Yun, and couples may be tired of calling him Kang Kang or Yunyun.

And at this moment, Zhou Cheng called him Xiaoyun, what does this mean, this means that Zhou Cheng has regarded him as his own from the bottom of his heart.

Kang Yun nodded solemnly, and then explained slightly embarrassed.

"Mr. Zhou, this ...... I'm ...... It's also nonsense, mainly because the dormitory area is too far from the outside street, and it's usually too lazy, so I came up with such a bad idea......"

"Hehe, it's okay, let's talk casually. What do you usually buy with drones?"

Kang Yun observed Zhou Cheng for a while and found that Zhou Cheng didn't seem to be joking, so he became a little serious, scratched his scalp and counted with his fingers.

"The load of this drone is too small, and if you put something more than 5 kilograms on it, it can only fly at an altitude of about 2 meters, so we rarely buy big loads such as drinks.

That is, buy cigarettes, chewing gum and the like, let the drone fly out with a small basket, there are notes and money in the basket, the boss receives it and puts the goods in the basket, and then we control the drone to fly back, that's it. ”

Knock knock knock......

As he was talking, there was a knock on the door, Wang Gang got up and opened the door, and Cai Xing and Cheng Ye entered.

"Mr. Zhou, did you call us?

"I can't talk about it, it's just that I occasionally saw Kang Yun's drone today and was a little inspired, and I want to ask you to come over and talk. ”

"Why, you're not going to make a drone, are you?"

"No, no, no, what am I doing with drones, I'm going to make something similar to drones, uh...... Wait a minute......"

Zhou Cheng glanced around, only to find that he didn't bring back the drone just now, or Kang Yun was smart, knowing what Zhou Cheng was looking for, he hurriedly controlled the remote control, and in less than two minutes, there was a click at the door.

The drone had landed safely on the ground.

Zhou Cheng picked up the drone, brought in the small bamboo basket hanging underneath, and put it on the desk to say to everyone.

"See, let's say the drone is magnified tenfold and the bamboo basket is magnified tenfold, so theoretically, is it possible to carry people?"

“…… This ......"

“…… This one...... It seems like...... Should...... Okay......"

"But...... Mr. Zhou, the theory is always the theory, this drone is enlarged and manned, or needs more technology to support, for example, our folded paper airplane, relying on the wind can fly, can also carry a few grams, more than a dozen grams of things to fly, but we can't say that the paper airplane can be magnified a hundred times to carry people, magnified paper airplanes can not fly, this is not scientific......"

Zhou Cheng's rebuttal had been expected by Cai Xing for a long time, so he just nodded slightly, and then handed over the paper on the table where he had written and drawn.

"This is the conclusion of my previous hasty deduction, in fact, this model is valid, it is a miniature version of a one-man aircraft, but the power system of this thing is still to be discussed.

For example, what flight it needs to rely on, whether it is electricity, oil, or other means, in addition to the load-bearing problem, flight altitude, speed, safety and other problems must be solved.

In addition, I am still considering a possibility, that is, can this thing be reduced as much as possible, such as blending into human shoes, sleeves, etc., so that people can fly automatically and soar into the blue sky without wind?"

Everyone present looked at each other when he said this, they were still thinking about the previous question raised by Zhou Cheng, and Zhou Cheng had already begun to raise the second question.

Cai Xing said with a dry smile.

"Mr. Zhou, your thinking is too advanced, we can't keep up, or else, I'll gather all the talents related to physics and dynamics on the 33rd, let's have a discussion and study it well?"

"Well, that's a good idea, hurry up, I'll refine my thoughts again!"

An hour later, Kang Yun followed Wang Gang to attend the top technical event in Qili Village.

In the No. 33 laboratory, led by Li Bin and Li Chunhua, more than a dozen technical expert groups deduced and demonstrated the ideas put forward by Zhou Cheng step by step.

At first, Kang Yun planned to listen seriously, but he also pretended to be serious, showing how serious and studious he was, but after listening to it for only five minutes, he felt sleepy.

So he hurriedly blocked the answering function of his ears and forced himself to put his mind on YY.

While others were spitting and discussing the feasibility of making people fly, Kang Yun's mind was all about how to show off to others, and the idea of this flying invention was obtained because of his own drone.

"I had two flight concepts in mind, one was to make it into a single-passenger airplane, which was relatively simple, and now there should be a similar powertrain on the market.

The second one is a bit more difficult, and the principle is similar to the single-wheeled balance bike played by young people, where we compress the powertrain into very small units and then hide it to make it look like it's flying out of thin air. ”

"I know this, it's like a beautifying antenna in a communication device, it looks like a tree, but in fact there is a hole in it. ”

"Yes, my initial idea is this, for example, if you can compress the braking system to the size of an insole and lift people from under your feet to fly. Or compress it into something else and tie it to the belt, so that it is easy for people to balance in mid-air. ”

Most of these people in Laboratory No. 33 were originally high-achieving students from colleges and universities, and they had seen a lot and learned a lot in Qili Village in the past two years, but even so, when they heard Zhou Cheng say this idea, everyone was afraid to answer with a white face.

Li Bin was the first to raise his hand and speak.

"Mr. Zhou, this ...... It seems a bit difficult...... The first one you mentioned, that is, to make a small plane is simple, but the second one, with all due respect, is probably not up to the end of our current technology. It is estimated that a flying machine compressed to the size of an insole may not be able to be made in another 100 years. ”
