Rekindle 2003

Chapter 48: Your Pesticide Drones Are All in One?
Facing the youngest who pretended not to understand, Peng Changxu still patiently explained, "You are wrong, youngest, one axis and one rotor, and there is only one variable in terms of force and torque.

If the variable torque structure is not considered, one axis can generate two coupled control quantities of force and torque.

UAVs move in six degrees of freedom in the air, and generally need three independent variables to control.

So the best form is three-axis, three-axis is enough, and the design of four-axis is too redundant. "

While talking, Peng Changxu drew a sketch on the draft paper.

Qing Yun was a little taken aback, but he had indeed seen a drone with three axes in his previous life.

Well, three axes and four axes don't matter.

Since Li Tai in "Tang Zhuan" can design the car engine into a gossip shape, why can't my brother change the drone into a three-axis one?

The triangle is the most stable!
"But, besides the aerial photography you just showed, what else can such a drone do?"

Peng Changxu put down his pen and twitched his lips, feeling very disgusted, "Yu Guo and the people are useless, after all, isn't it a toy?"

Mark patted his head, "It can also track weather data. It wasn't just reported in the news a few days ago that the Atmospheric Administration in the beautiful country used drones to track tropical storms."

"You can also spray pesticides. Cherry Blossom has used drones to spray pesticides more than ten years ago." Zhuo Lang also interjected.

Peng Changxu rolled his eyes helplessly, "Can we do something practical? Don't fool me for being a fool. Those two are large drones."

Qing Yun figured out his way.

For the country and the people, right?

easy to do!

This kind of person is the best fool!
Emmm, it's my second brother...

Persuasion, better persuasion.

He still picked up the phone, and tied a pencil underneath Qin Manman's rubber band, "Look good."

The drone took off from his desk and landed on Qin Manman's desk.

Without waiting for what Peng Changxu said, he said directly, "Didn't you buy a circuit board on eBay last year? How long did it take you from placing the order to receiving it?"

Peng Changxu pondered for a while, "About two weeks? I forgot the exact time. Later, I found out that it is better to go to the Chenghuangmiao electronic market to buy...

I see what you mean, you mean, you can use it to deliver express?This is indeed an idea, no need to go to the post office. "

The more he thought about it, the more reasonable it became, his eyes lit up involuntarily.

Online shopping must be the future trend, followed by the contracting and distribution of massive goods.

Looking at his innocent eyes, Qing Yun rolled her eyes in her heart.

Drones deliver express...

Think college students are not easy to use, right?

spendthrift!
Toys are what make money!

But painting cakes is still a must.

Yumin solved it, now it's time for Yuguo.

Qing Yun patted him on the shoulder, "Second brother, in fact, the biggest use is in pesticides.

If you design such a small UAV that can carry 50KG in the future, it is not an exaggeration for the country to award you a medal. "

Peng Changxu was stunned, "Pesticide? Is this thing worth a medal?"

Qingyun picked up the phone, pointed the tip of the pen at him, and made a "da da da da" sound from his mouth, then flew to the top of his head, and dropped an eraser "Boom!"

"Add an active phased array radar, perfect!"

Qing Yun licked his lips, and another sea of ​​horses appeared in front of his eyes.

In the desert of the Middle East, in the mountains of Panmunjom, in the forest near Norway...

All over the world are lands flowing with milk and honey.

Everyone was stunned.

This……

Even a girl who is not interested in the military at all understands what he means.

Because they have a physics teacher who is a military fan, he often explains the physics principles of some equipment in class.

Zhou Li pointed to the mobile phone in his hand, "Damn it! Are you a pesticide drone? Are you sure you are killing pests?"

The corners of Peng Changxu's mouth trembled, "Youngest, active phased array radar? The bug you're fighting is the Queen of Blades, right?"

Qing Yun shook her finger, "Where are you thinking? You know, I am the son of a farmer, and I love to grow something."

"Yes! Yes, yes! Your hometown likes to grow strawberries the most!" Tang Qianying didn't hold back her smile, her eyes wandered on Qin Manman's body.

Everyone lay on the table laughing hard.

Qin Manman blushed, glared at Qingyun, and then went to fix the sloppy 'sister-in-law' beside him.

She now finds that Tang Qianying is too tricky, and the identity of that god-sister is too buggy.

The more Qin Manman thought about it, the more angry he became, he kicked Qing Yun under the table.

Qing Yun rubbed her legs, a little dumbfounded, she didn't keep the door open, it's none of my business!
If you agree, I can gag her now.

Frowning at everyone, he forcibly brought back the topic, "A radar is installed on the drone to improve the accuracy and facilitate the work of the farmer uncle. Isn't it just focusing on the integration of observation and shooting now?"

Peng Changxu laughed angrily, "Survey and fight together? Are you talking about killing insects?"

Qing Yun spread his hands and said impatiently, "Why not, mold is also a bug. Okay, is it enough for the country and the people?"

Peng Changxu rubbed his hands in embarrassment, and he also understood that just now he was a bitch and hypocritical.

He also knew in his heart that what Qing Yun asked him to do was actually a drone for the civilian consumer market.

After all, making money is the last word.

The six gourd babies have no fart money now, how to make money is the most important thing, there is no reason for others to make money for themselves to spend.

But it doesn't affect him to design 'pesticide' drones later when he has money.

It is a normal operation to convert civilians to military when necessary.

"Well, see for yourself. To complete such a drone, what do you think is the best major for you to study?"

Peng Changxu scratched his head and asked uncertainly, "Automation?"

Qing Yun opened the college entrance examination guide and pointed to several majors, "Automation, communication, and machinery are all fine."

Peng Changxu took it over and looked carefully, "Let's communicate. If it doesn't work, I can do something else."

Qing Yun sighed, there is no way, automation and machinery are now tiankengs.

At this time, a voice suddenly sounded next to them, "Alas...you, if you don't learn automation and machinery, what will happen to the country's development in the future!"

Everyone was startled, and they took a closer look, and at some point, physics teacher Wang Jianjun touched them.

"Old Wang..."

Wang Jianjun smiled wryly, and waved his hand, "It's okay, I understand, the reality is so cruel. When I farted just now, I just feel emotional when I'm old."

Seeing the uncomfortable faces of the students, Qing Yun quickly interjected, "Old Wang, it's okay, the market will adjust. If there is a shortage of people, it will naturally become rare and expensive."

Wang Jianjun pondered for a while, "You're talking about the same reasoning. Nowadays, there are swarms of swarms in any major that is hot, and then the market is indiscriminate."

As soon as he was in a good mood, he slapped Qing Yun on the back, "Hey, I'm counting on you for the teacher's bonus this year."

Faced with such teasing, Qing Yun scratched his head and could only smile shyly, "Old Wang, I will do my best."

"Don't put too much pressure on it. If we teachers really care about this, we would have gone out to start cram schools a long time ago, and we should just play with a normal mind."

Wang Jianjun patted him on the shoulder with a smile, and walked to the podium, "If you have any questions, ask them quickly, you don't have much time left."

Before he finished speaking, he was surrounded by a sea of ​​people.

The physics questions in this monthly exam were extremely difficult. Even in the base class, many people were hit hard by the three multiple-choice questions.

"Hmph! I put these three questions at the top to teach you a lesson. Your psychological quality is generally not good enough.

Jiang Xudong, you are a typical example. When you encounter a difficult problem before, your mentality collapses. You look at the following questions yourself. The last big question is so simple, you are empty. "

Jiang Xudong was flushed with embarrassment. He spent too much time on the first three multiple choice questions.

Wang Jianjun nodded Qingyun, "Fortunately, Qingyun reminded me, otherwise, what would you do if you encountered such a thing in the college entrance examination?"

He retired after teaching this year, but when he thinks about this problem, he is more afraid than other teachers of the Mesozoic and New Generation.

Especially the group of academic masters in the base class, each one of them was terribly proud.

If they can't solve the problem, they will swear to solve it to death, which is their pride.

It is also the reason why they can become masters.

They are used to doing nothing for an hour or so after finishing the papers, and they are confident enough that they will not care about the loss of time in the examination room.

However, in a specific situation like the college entrance examination, this kind of self-confidence will hurt them.

Wang Jianjun was not worried about being wrong, and the facts have proved that most of those who gave up the math test in 03 were usually good students.

When Qin Manman heard the words, he glared at Qing Yun with beautiful eyes, and wrote angrily on the note, "It's a good plan! Try to take advantage of me, right!"

Usually during the lunch break at noon, she actually wears quite a lot.

Since Qingyun won the monthly exam, she can only wear fat clothes as agreed.

However, Qing Yun refused to accept this account.

He swears, with the conscience of heaven and earth, this time it is definitely not for her body.

I am changing my fate against the sky, okay!
Let them know that if you encounter difficulties in the examination room, don't get dizzy.

Especially Jiang Xudong's mentality is fragile.

In fact, as long as they persevere through the exam, their rankings will not be much different than usual.

After all, in the college entrance examination, it is the ranking, not the score.

Even if it's a mess, as long as you don't give up the exam, there will be room for manipulation later.

My golden finger is not for nothing.

2003 was an extremely magical year for the college entrance examination.

As for Qin Manman, he could only write, "Hehe...I'm doing this for your own good."

Looking at the words on the note paper, Qin Manman grabbed his arm bitterly.

Qing Yun rubbed her little hand, and continued to write, "Bringing that thing to sleep makes you feel uncomfortable, brother, this is for your sake.

Besides, my hands are the best Bra in the world, okay?It can be wrapped, breathable, and has a massage effect. "

Qin Manman's face was flushed with embarrassment, and he took a marker pen and wiped frantically on the note paper.

Stinking rogue!
After stomping his foot, Qin Manman decided to ignore him for 40 minutes and concentrate on doing his own thing.

Seeing this, Qing Yun turned her head back and curled her lips.

I don't know who it is, but at noon, I always quietly untie Bra, let myself hug her from behind, and then sleep like a dead pig.

Emmm...

Little pig?
Seriously do the questions, the time is actually very easy to mix.

But today, everyone in the base class felt that every second was hard to bear.

Because of the physical examination for the college entrance examination tomorrow, the school ordered everyone to have dinner at school tonight.

There was an accident in a certain school last year, and a bunch of students whose transaminase exceeded the standard were found.

Although the incident last year was caused by the students living in the school, this time Jincheng No. [-] High School required all students to eat at school.

After all, there are quite a lot of unreliable parents now.

Just when the eyes of a group of people were about to turn green from hunger, the cafeteria staff and teachers, pushing the dining cart and carrying buckets, entered the door.

Looking at the dishes on the dinner plate, the boys rioted.

Even Qing Yun, who came from the countryside, was a little bit speechless.

Half a piece of corn, half a sweet potato, a cucumber, six cherry tomatoes, a steamed bun, and a bowl of porridge.

The monks have some soybean oil and tofu anyway!

How can I eat this clear soup with little water!
Girls said it doesn't matter, they just want to lose weight.

During the preparation for the college entrance examination, the strong fatherly love and motherly love made them gain a lot of weight.

Even Qin Manman gained two kilograms in weight this month.

"Bear with me, you can eat whatever you want after the physical examination tomorrow, and be honest tonight."

Li Fangping, as the head teacher, took the lead in eating, while the teacher from the Moral Education Department was videotaping the meal for parents to check later.

They are all only children, and they are both the little sun and the little moon in the family. The school has taken a lot of responsibility for doing this this time.

"Oh, by the way, don't eat cucumbers if you have a bad stomach, it's easy to have diarrhea." Li Fangping suddenly remembered this while biting the cucumber, and hurriedly reminded him.

Qing Yun pouted, and put the cucumber aside.

It was him.

Seeing this, Qin Manman picked up the sweet potato from the dinner plate and exchanged it with him, "I want to lose weight, so I have to eat less carbohydrates."

"Be careful, don't subtract the wrong place, it's not easy for me this month." Qing Yun whispered while biting the corn.

Qin Manman was stunned for a while before he realized that he stretched out his little hand and wreaked havoc on his thigh, "Student, I find that you are becoming more and more indecent now!"

Qing Yun pushed her little hand away angrily, "If I can't eat it, I'm not allowed to splurge!"

Qin Manman blushed, and then grabbed him again angrily, "You've eaten too little!"

Thinking of those fat times thrown away, she felt a burst of fire in her heart.

He is uncomfortable, and she is also uncomfortable.

Qing Yun clicked his tongue twice, "Say it as if I took the initiative every time."

Qin Manman's face was feverish, his silver teeth were gritted secretly, and his small hands were desperately grabbing his thigh.

Then she turned her head angrily and stared at Tang Qianying.

It's all the Tianshan Child Elder's fault!

Qin Manman was very depressed.

It would be fine if she didn't know anything, but after reading so many weird cartoons, she found sadly that she was not pure anymore.

After the first shy period between the two of them, now she also started to take advantage of her boyfriend from time to time.

Emmm...

No, she is sick.

Suffering from a disease called skin hunger and thirst, when the two of them stay together, they always want to hug each other.

Tang Qianying was stared inexplicably, and looked at her innocently, "Sister and sister, what are you fussing about?"

She said that she hadn't had tea with her brother and sister for several minutes.
