Faced with the youngest who pretended to understand, Peng Changxu patiently explained, "You are wrong, youngest. Each axis and one rotor have one variable in terms of force and torque.
If Without considering the variable torque structure, one axis can generate two coupled control quantities of force and torque.
The movement of a drone with six degrees of freedom in the air generally requires three independent variables to control.
p>
So the best form is three axes, three axes is enough, and a four-axis design is too redundant."
Peng Changxu said while drawing a sketch on the draft paper.
Qing Yun was a little stunned, but he had indeed seen a three-axis drone in his previous life.
Well, three axes and four axes doesn't matter.
Since Li Tai in Tang Brick can design the car engine into a Bagua shape, then 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 curled his lips in disgust, “Yu Guo It’s useless to the people, it’s not a toy after all.”
Mark patted his head, “It can also track weather data. Didn’t it just appear in the news a few days ago? The National Atmospheric Administration uses drones to track tropical storms."
"You can also spray pesticides. The Sakura area started using drones to spray pesticides more than ten years ago," Zhuo Lang. He also kept his mouth shut.
Peng Changxu rolled his eyes helplessly, "Let's do something practical, why don't you treat me like a fool? Those two are large drones."
Qing Yun Find out his way.
Serving the country and the people, right?
Easy to deal with
This kind of person is best fooled
e, he is his second brother
p>Persuade, better persuade.
He still picked up the phone and tied a pencil underneath with Qin Manman's rubber band, "Watch it."
The drone took off from his desk, and then Landed on Qin Manman's table.
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 from placing the order to receiving the goods?"
Peng Changxu thought for a while, "About two weeks, I forgot the specific time. Later I found that it is better to go to the Chenghuang Temple Electronic Market to buy it
I understand what you mean, you mean, you can use it to give away Express delivery is indeed an idea, there is no need to go to the post office."
The more he thought about it, the more it made sense, and his eyes lit up involuntarily.
Online shopping must be the trend in the future, and what follows is the contracting and distribution of massive amounts of goods.
Qing Yun looked at his innocent eyes and rolled her eyes in her heart.
Drones deliver express delivery
You think it’s hard for college students to use it, right?
Prodigal son
Toys are the things that make money< /p>
It’s just a cake painting.is required.
It has been solved for the people, now it is time for the country.
Qing Yun patted his shoulder, "Second brother, in fact, the biggest use is still in pesticides.
If you design this kind of small drone in the future, it can carry 50kg , it’s not an exaggeration for the country to award you a medal.”
Peng Changxu was stunned, “Pesticides are worth a medal.”
Qing Yun picked up the phone and pointed it at the tip of his pen. He looked at him and made a "da da da da" sound in his mouth, then flew to his head and dropped a rubber "boom"
"Install an active phased array radar, perfect."
Qing Yun licked her lips, and another sea of horses appeared in front of her eyes.
In the deserts of the Middle East, in the mountains of Panmunjeom, in the forests near Norway
There are lands flowing with milk and honey everywhere in the world.
Everyone was stunned.
This
Even girls who are not interested in the military at all understand what he means.
Because they have a physics teacher who is a military fan, and he often explains the physics principles of some equipment in class.
Zhou Li pointed at the mobile phone in his hand, "Holy shit, this is a pesticide drone. Are you sure you are killing pests?"
Peng Changxu's mouth trembled, "Old "Hey, the active phased array radar bug you are fighting is the Queen of Blades, right?"
Qing Yun shook her finger, "You know what you are thinking, I am the son of a farmer, What is your favorite thing to grow?"
"Yeah, yes, your hometown likes to grow strawberries the most." Tang Qianying couldn't hold back her smile, her eyes wandering around Qin Manman.
Everyone lay on the table laughing until they died.
Qin Manman blushed with embarrassment, glared at Qing Yun, and then went to fix the yawning sister-in-law beside him.
Now she is finding more and more that Tang Qianying is too difficult, and the identity of her god-sister is too buggy.
Qin Manman became angrier as he thought about it, and kicked Qing Yun under the table.
Qing Yun rubbed her legs, a little confused about whether to laugh or cry. She didn’t shut the door, it’s none of my business.
If you agree, I can stop her now.
Raising an eyebrow at everyone, he forcibly brought back the topic, "A radar is installed on the drone to improve the accuracy and make it easier for the farmers to work. Now we are focusing on the integration of surveillance and attack."
Peng Changxu laughed angrily, "Are these words for killing insects?"
Qing Yun spread his hands and said impatiently, " Why not? Molds are also bugs. Okay, that's enough for the country and the people."
Peng Changxu rubbed his hands in embarrassment, and he also understood that he was being pretentious just now.
He also knew in his heart that what Qing Yun asked him to make was actually a drone for the civilian consumer market.
After all, making money is the last word.
The six gourd boys have no money now., how to make money is the most important thing, there is no reason to let other people make money to spend on yourself.
But this does not affect his ability to design pesticide drones later when he has money.
It is a normal operation to transfer civilians to the army when necessary.
"Well, you can see for yourself. In order to complete such a drone, which major do you think is best?"
Peng Changxu scratched his head, unsure. Asked, "Automation"
Qing Yun opened the college entrance examination guide and pointed out several majors, "Automation, communications, and machinery are all acceptable."
Peng Changxu took it and looked at it carefully. Look, "Let's just communicate. If I can't do it, I can do something else."
Qing Yun sighed, there was no way, automation and machinery were like sinkholes now.
At this time, a voice suddenly sounded next to them, "Oh, you guys, you don't learn automation and machinery. What will happen to the country's development in the future?"
Everyone was startled. , taking a closer look, I don’t know when the physics teacher Wang Jianjun touched everyone.
"Old Wang"
Wang Jianjun smiled bitterly and waved his hand, "It's okay, I understand, reality is so cruel. When I farted just now, I am an old man and sighed. "
Seeing some discomfort on the students' faces, Qing Yun quickly interrupted, "Mr. Wang, it's okay, the market will adjust. If there is a shortage of people, it will naturally become scarce."
Wang Jianjun thought about it for a while, "You are also saying the same thing. Nowadays, people rush to get into whatever major is hot, and then the market is overrun."
As soon as he was in a good mood, He slapped Qing Yun on the back and said, "Hey, teacher, I'll leave it to you for this year's bonus."
Faced with such teasing, Qing Yun scratched her head and could only smile shyly. , "Mr. Wang, I will do my best."
"Don't put too much pressure on me. If we teachers really cared about this, we would have gone out to open cram schools long ago. Just use your normal mind."
Wang Jianjun smiled and patted him on the shoulder, then walked to the podium, "If you have any questions, ask them quickly. There is not much time left for you."
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 just to teach you people a lesson. Your psychological quality is generally not good enough.
Jiang Xudong, You are a typical example. When you encounter a difficult problem in the front, your mentality will collapse. Look at the next questions for yourself. The last big question is so simple, and you can't even think about it."
Jiang Xudong's face was full of shame. Blushing, he spent too much time on the first three multiple-choice questions.
Wang Jianjun nodded at Qing Yun, "Fortunately Qing Yun reminded me, otherwise what would you do if you encountered this kind of thing in the college entrance examination?"
He has finished teaching this this year Retired after one term,But when I think about this problem, I feel more scared than other Mesozoic and New Generation teachers.
Especially the top students in the base class are all extremely proud.
If the problem cannot be solved, they will never give up and go to death to solve it. This is their pride.
This is also the reason why they can become top academics.
They are used to having nothing to do for an hour or so after finishing the paper, so they are confident enough not to care about the loss of time in the examination room.
However, in specific situations like the college entrance examination, this kind of self-confidence will harm them.
Wang Jianjun was not worried about his mistakes. Facts have proved that most of those who gave up the math test in 2003 were good students.
When Qin Manman heard this, he glanced at Qing Yun with his beautiful eyes, and angrily wrote on the note, "You are so calculating and trying to take advantage of me, right?"
As usual During lunch break, she actually wore a lot of clothes.
Since Qing Yun won the monthly exam, she could only wear fat clothes as agreed.
Qing Yun refused to accept the account.
He swore to the conscience of heaven and earth that this time it was definitely not for her body.
I am going against the will of heaven to change my fate, okay?
Let them know that if they encounter difficulties in the examination room, they should not be discouraged.
Especially Jiang Xudong's fragile mentality.
In fact, as long as they persist in completing the exam, their rankings will not be much different from usual.
After all, the college entrance examination is about ranking, not scores.
Even if you fail, as long as you don’t give up on the exam, there will be room for maneuver 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, "Haha, I am doing this for your own good."
Looking at the words on the note, Qin Manman tugged at it bitterly. Touched his arm.
Qing Yun took her little hand and continued to write, "If you sleep with that thing, you will not feel comfortable yourself. Brother, this is for your sake.
Besides , My hands are the best in the world
A, they can wrap, are breathable, and have massage effects.”
Qin Manman’s face turned red with embarrassment. He took a marker and scribbled wildly on the note paper.
Smelly hooligan
After stomping on him, Qin Manman decided to ignore him for 40 minutes and concentrate on doing his own thing.
Seeing this, Qing Yun turned back and pouted.
I don’t know who it is, but he always quietly untied her at noon
a, let himself hold her from behind, and then slept like a dead pig.
e
Little Xiangzhu
If you do the questions carefully, the time is actually very easy to use.
But today, everyone in the base class felt that every moment was difficult.
Because of the physical examination for the college entrance examination tomorrow, the schoolEveryone is ordered to have dinner at school tonight.
There was an accident in a school last year, and a bunch of students with excessive transaminases were found.
Although last year’s incident was caused by students living on campus, Jincheng No. 4 Middle School requires all students to eat on campus this time.
After all, there are quite a lot of unreliable parents nowadays.
Just when a group of people's eyes were almost turning green from hunger, the cafeteria staff and teachers came in pushing a dining cart and carrying buckets.
Looking at the food on the plate, the boys rioted.
Even Qing Yun, who came from the countryside, was a little bit unable to speak.
Half corn, half red potato, a cucumber, six cherry tomatoes, a steamed bun, and a bowl of porridge.
The monks all have some soybean oil and tofu after all
How can I eat this clear soup with little water?
The girls said it doesn’t matter, they just want to lose weight.
During the preparation for the college entrance examination, the strong love from their father and mother caused them to gain a lot of weight.
Even Qin Manman gained two kilograms in weight this month.
"Just bear with me. You can eat whatever you want after the physical examination tomorrow. Be honest tonight."
As the head teacher, Li Fangping took the lead in eating, and next to him was a teacher from the Moral Education Department. Video recording for parents to review later.
Both of them are only children, and they are both the little sun and little moon of the family. The school also bears a lot of responsibility for doing this this time.
"Oh, by the way, don't eat cucumbers if you have a weak stomach. It's easy to have diarrhea." Li Fangping suddenly remembered this while biting the cucumber and quickly reminded him.
Qing Yun curled her lips and put the cucumber aside.
That’s him.
Qin Manman saw this, picked up the sweet potatoes on the dinner plate and exchanged them with him, "I want to lose weight, so I need to eat less carbohydrates."
"Be careful, don't lose the wrong weight. It’s not easy for me to get a place this month,” Qing Yun said softly while biting the corn.
Qin Manman was stunned for a while before he realized what was happening. He stretched out his little hand and wreaked havoc on his thigh, "Classmate, I find that you are becoming more and more immoral now."
Qing Yun pushed her little hand away angrily, "If you can't eat it, why don't you allow me to have sex with you?"
Qin Manman's face turned red, and then she grabbed him again angrily. "You haven't eaten enough."
Thinking of those fat pieces thrown away, she felt a fire in her heart.
He feels uncomfortable, and so does she.
Qing Yun clicked her tongue twice, "It's like I take the initiative every time."
Qin Manman's face was burning, his silver teeth were biting secretly, and his small hands Holding his thigh tightly.
Then he turned angrily and glared at Tang Qianying.
It’s all the Tianshan Child’s fault
Qin Manman felt very depressed.
It would be okay if she didn’t understand anything at all, but after reading so many weird comics, she sadly discovered that she was no longer pure.
After getting over the initial shyness period between the two of them,Now she also starts to take advantage of her boyfriend from time to time.
e
No, she is sick.
Suffering from a disease called skin hunger syndrome, when the two of them stay together, they always want to hug each other.
Tang Qianying was stared at inexplicably and looked at her innocently, "Brother and sister, why are you so angry?"
