Ji Yue pretended not to hear.

"Ji Yue !!" The person behind him screamed again, crisp and loud.

"Ah Yue, call you." Qin Ying didn't know why, so he reminded him.

At this time, Ji Yue couldn't pretend that he couldn't hear it, so he could only turn around slowly, the people who called him were not Chen Mu and An Huai, who were they?

Chen Mu and An Huai were the first to arrive here, and the two of them had been waiting for Ji Yue's arrival, and now they finally waited, not to mention how excited they were.

Since the last rematch, the two have been thinking about Ji Yue, and every time the two encounter any problems in the research and creation process, they will think of him even more.

Especially Chen Mu, although Ji Yue refused to cooperate with them last time, as long as he thought that Ji Yue easily solved their problem with the remote control plane last time, he wanted to cooperate with Ji Yue even more.

He wondered what kind of sparks they could collide with if they cooperated.

This trip to the finals, in addition to looking forward to the results of the game, is to be excited to see Ji Yue again.

So the two came early, and they also intimately occupied the dormitory position for Ji Yue.

"Long time no see! Ji Yue. Chen Mu pulled An Huai and ran over excitedly.

“…… It didn't take long. Ji Yue didn't have any excited expression, and said without being salty or indifferent.

It's only been a month and a half since the rematch, why hasn't it been a long time?

Chen Mu didn't notice Ji Yue's coldness at all, and still said excitedly: "But when you come, we have reserved a bed for you in the dormitory, you can just go directly." ”

That's right, they're that caring.

Ji Yue: "...... "I really thank you."

"You two kids, you're weird." Qin Ying said with a smile, she likes such handsome and good-looking children.

"Let's go, Ah Yue, you go to the dormitory to rest for a while, and then let's go out for a walk and have a meal."

"Okay, Aunt Qin." Ji Yue had no choice, it was not good to brush the two of them in person, so he could only follow.

Su Qingyun was also dragged away by Li Xiaoxiao, and Qin Ying followed to take a look.

There are four people living in one room, and in addition to the three of them, there is also a girl, who is Li Xiaoxiao's teammate, named Zhang Xia.

Zhang Xia was dressed plainly, looking plain and white, and when she saw the three of them walking in, she smiled shyly and looked very good-tempered.

"Qingyun, Xiaofang, this is my teammate, called Zhang Xia." Li Xiaoxiao introduced them in a small chatter.

"Hello." Su Qingyun smiled and said hello, "My name is Su Qingyun." ”

"I ...... I know you. Zhang Xia spoke a little stumbling, and her face was slightly red.

Of course she knew Su Qingyun, and their group was the first place in the rematch, which left a deep impression on everyone, including her.

Zhang Xiaofang is outgoing and quickly greeted her.

Although the four girls have different personalities and come from different places, they can be regarded as getting along well when they look at it.

Everyone chatted casually for a while, and Su Qingyun packed the luggage he brought.

Although the time of this competition was only three or four days, her mother had not returned to the capital for a long time, and Su Qingyun still wanted to stay with her for two more days.

And she also promised the teacher to go to the math talent group to have a look, maybe there will be some delay here, so this time she brought more luggage than before.

It's only three o'clock in the afternoon, and the game will start the day after tomorrow, so they don't have any nervousness now, but have been chatting about all kinds of delicious and fun places in the capital.

"I finally came to the capital once, I really want to go to see the Forbidden City and climb the Great Wall." Zhang Xiaofang looked yearning.

Li Xiaoxiao said indifferently: "If you want to go, you can go, let's play early, don't worry." ”

"Do you want to go?" Zhang Xiaofang thought about it as well, so she asked the two.

"Imagine!" Li Xiaoxiao didn't think twice.

Su Qingyun shook his head and said apologetically: "I'm sorry, there are some things on my side, and I may not be able to go." ”

"What's wrong?" Zhang Xiaofang and Li Xiaoxiao looked at each other.

"I want to accompany my mother home to have a look." Su Qingyun said.

Zhang Xiaofang suddenly remembered that Su Qingyun's mother was from the capital, and now that she came over, she would definitely have to go back to take a look.

"Then you go with Auntie, I'll go play with Xiaoxiao." Zhang Xiaofang said.

"Uh-huh, you guys have fun."

Su Qingyun looked at the time, it was already half past three, and she first went to Ji Yue's dormitory to find him.

Ji Yue was annoyed by Chen Mu and An Huai, and was worried about how to get out, as soon as the door opened, he saw Su Qingyun coming, and immediately breathed a sigh of relief.

"What's wrong? Your expression. Su Qingyun looked at Ji Yue's expression as if he had survived the catastrophe, and was a little funny.

"It's nothing, let's go." Ji Yue spoke a little fast, and he couldn't wait to leave immediately.

But he was still a step late, Chen Mu had already seen Su Qingyun, and he hurriedly greeted, "Classmate Su, hello!" ”

Stretching out his hand not to hit the smiling person, Su Qingyun also greeted with a smile: "Hello." ”

"Classmate Su, I heard Ji Yue say that you are better than him, so can you help us take a look at this?"

"What?" Su Qingyun didn't know why.

"This is it." Chen Mu touched something from behind like a trick.

Su Qingyun fixed his eyes and saw that this was a ......

Plane?

Ji Yue sighed helplessly, Chen Mu and An Huai seemed to be on the same plane as if they were on the plane, he helped them get a remote-controlled plane last time, but they didn't expect to meet this time, and they found another one.

However, this time the aircraft is clearly an improvement over the last one, and it is more well-made, and it is clear that they have designed and built it after careful consideration.

But this time, instead of making a remote-controlled aircraft, they plan to find a different way to start from the power of the aircraft and really make a small, flyable aircraft.

But it was this power problem that stumped the two, and they thought of many ways and tried many different aircraft to assist, but to no avail.

After all, this is not a real aircraft, and the aviation kerosene used in the real aircraft cannot be used in this small aircraft.

The last time they played in the rematch, the two of them were small self-propelled airplanes, which could fly without electricity, but the time was too short and could only be regarded as a subtle toy.

What the two want to do is a small plane that can fly for a long time without external force.

But the two thought hard for a long time, but they still didn't solve this problem, so they could only hope for Ji Yue.

Just now, the two of them had been harassing Ji Yue, wanting him to come up with a solution, but suddenly like this, Ji Yue had no choice, Chen Mu and An Huai wanted to drag him to study together.

Ji Yue was not very interested in this, so he always wanted to get out.

Su Qingyun listened to Chen Mu's aircraft design concept and did not speak.

Chen Mu saw that she didn't have any expression, and he felt a little worried for a while, and he asked carefully, "You don't think the two of us are whimsical, do you?" ”

"Not really." Su Qingyun shook his head with a smile, "Your ideas are very good, and the design is also very interesting." ”

To be honest, in this era, it is really rare to see such a vigorous imagination and excellent thinking ability, they have talent, dare to think and dare to do, and they are already stronger than the vast majority of people.

As long as they are cultivated well, the future of these two people is limitless.

Su Qingyun didn't want to perfunctory the two, she thought about it carefully and said: "Your idea is very good, but if you really want to implement a small plane that can fly for a long time, this is too complicated. ”

Chen Mu and An Huai's expressions dimmed, they also knew that their idea was too bold, but this was what their dream was going to be.

"We'll keep figuring it out." It was An Huai who spoke, his face was determined and he did not flinch.

Su Qingyun smiled again, this is the spiritual quality that a scientific researcher needs to have, both of them have it, so they will definitely succeed in the future.

"I'm not done yet."

Su Qingyun continued: "Have you ever played with bamboo dragonflies? ”

"Of course I did." The two nodded affirmatively.

Nowadays, there is a lack of entertainment activities, whether in the city or in the countryside, children play with similar things, and bamboo dragonflies are definitely an indispensable existence in everyone's childhood memories.

"The reason why the bamboo dragonfly can fly is because when the rubbing of the hand gives the bamboo dragonfly a rotating speed, it will generate lift, and lift is the power that the bamboo dragonfly can take off."

"So the rotors of our helicopters are similar to bamboo dragonflies?"

"Why are you obsessed with making a smaller version of a large plane instead of a miniature version of a helicopter? That's what is easier to achieve. ”

Su Qingyun asked the two with a smile, and Chen Mu and An Huai were stunned.

The miniature version of the helicopter she is talking about is actually a drone of later generations.

Inside the drone is a motor, and when the motor rotates, the propeller generates lift, which makes the drone take off.

She said this to show them another direction.

Chen Mu thought for a moment and asked, "What is the use of this miniature helicopter you are talking about?" ”

Hearing this question, a lot of things flashed through Su Qingyun's mind for a while.

In later generations, UAVs are generally divided into military UAVs and civilian UAVs, and civilian UAVs can be divided into consumer and industrial grades, most of which are enthusiasts who like to shoot for aerial photography and the like, and industrial grades are generally used in meteorology, agriculture, scientific exploration, security communications and so on.

Military UAVs can be divided into single-purpose and multi-purpose two-piece, single-purpose unmanned reconnaissance, unmanned combat, communication interruption, electronic jamming, multi-purpose is the UAV that refers to the integration of reconnaissance and fighting.

It can be said that drones have been used in all aspects of life and are extremely useful.

But even when she thought of this, Su Qingyun didn't say anything, what she had in her mind was just some information in the later generations, and it was very difficult to really realize.

There is no need for her to sketch a beautiful blueprint for the two of them now, she only needs to point out a direction for the two of them, and the rest is to work her own.

"It's up to you to ask yourself, how far can you go?" That's all she said.

Chen Mu was stunned, as if he didn't expect to get such an answer.

But he nodded anyway and said thank you sincerely.

An Huai also thanked him seriously.
