There was also a large group of children, a boy in his teens, who was operating, and the plane really took off and landed as if it were a real airport.

Zhang Youchen wanted to try it, but the little boy had no intention of stopping, and kept playing, about seven or eight times.

Because of the limited time, Lin Jiamei finally couldn't help it, and said to the boy: "This brother, can you let your brother play too?" ”

"I haven't had enough of it."

"You've played it several times, let my brother play it once."

"What's wrong with my son playing so many times? This is not your family, you care about my son? A fat woman came up and said loudly.

The surrounding tourists all took a look.

Lin Jiamei was unhappy, but she didn't bother to quarrel with her, so she pulled Zhang Youchen and prepared to play with others.

Who knows if this Zhang Youchen is like taking some medicine, he has to wait to play.

"Baby, if you wait like this, our mission will not be completed."

"But, I really want to play it once." Zhang Youchen looked at her pitifully.

The boy felt compassion, got out of the way, and said, "Why don't you play with it once?" ”

Who knew that the fat woman pushed her son, "You play with yours, why are there so many things." ”

Lin Jiamei was so angry that her face was flushed.

[Damn, this woman is sick, how can she educate her children like this]

[This kind of person is selfish and only thinks about taking advantage, it's disgusting]

[Lin Jiamei is too cowardly, I'll slap her if it's me]

Moonman walked over.

From entering the science and technology museum just now, Yue Man saw a group of teams wearing XX kindergartens at a glance.

They were supposed to be an out-of-school institution, specially brought the children in the class to visit, led by a staff member wearing a T-shirt with the words "Science and Technology Museum", a young man in his twenties, and some teachers and parents around him, who also wore T-shirts of the same color as the children.

Those children are about the same size as Doudou, and they are probably all kindergarten students.

At the beginning of the month, Man walked over and said sweetly to the staff: "Hello, my son is very interested in technology, but unfortunately I don't know anything, can I trouble my son to follow you?" ”

When the staff looked at it, it was too beautiful!

It's like the girlfriend of his dreams.

He immediately said, "No problem." But the safety of the child ......"

Unexpectedly, Doudou interrupted him, "I will be responsible for my safety." ”

So it was only two minutes, and at the beginning of the month, Man entrusted Doudou to a professional organization, and then she sat in the rest area, at ease.

The airplane exhibition area that Zhang Youchen wanted to play was right next to the rest area, so the conversation between Lin Jiamei and the fat woman was heard by Yue Man.

Originally, she thought that Lin Jiamei would reason with the fat man, but who knew that Lin Jiamei was so cowardly and was said to be red-faced.

At the beginning of the month, Man couldn't get used to it.

She stood up, patted her buttocks, and walked over.

The teenage boy was still playing under the protection of his mother.

At the beginning of the month, Man pulled Lin Jiamei aside, pulled Zhang Youchen closer to the boy, and said, "You have played enough, let the other children play." ”

Seeing another adult let him give up his seat, the boy subconsciously looked at the fat mother who was playing with his mobile phone, "Mom".

The fat woman came over with her ass swinging, she looked Xia Chuman up and down, and said angrily, "Who are you?" ”

Yue Man smiled faintly, "Who am I and still need to report to you?" Let your precious son give way. ”

At the beginning of the month, Man's attitude undoubtedly angered the woman, and she released the classic quote just now, "This is not your family, even if my son plays for a day, you can't care about it." ”

Moonman raised an eyebrow, "Really?" ”

With that, she pushed the boy away and stood by the console herself.

"You, you actually pushed my son." The fat woman was so frightened that she screamed and pounced.

Yueman only blocked lightly, and the woman could only flutter half a meter away from Yueman, and she couldn't reach Yueman's body.

The surrounding tourists were stunned.

This woman looks so thin, so powerful, and such a heavyweight can't get close.

[Hahaha, Sister Man is mighty]

[I knew that this kind of thing had to be done by my Sister Man, and when I met such a cheeky person, I had to be treated by Sister Man]

[But is it a bit too much at the beginning of the month, the child is fine, why does she want to push other people's children aside]

[What's wrong with pushing, and it's not hard, can the bear child only let it? ] Moon Man is not a, there is no need to get used to him]

The fat woman began to swear words, and at the beginning of the month, Man pushed her three meters away without even thinking about it.

"What are you? You have the ability to charter your son, not to mention that he is not your son, oh, I understand, looking at your appearance, it should be a junior, this is your lover's child, right? ”

Lin Jiamei walked over angrily, "What are you talking nonsense?" ”

"Hey, hey, it's really a deep love for wives and concubines."

The tourists looked like they didn't think it was a big deal, and they all gathered around.

Compared with eating melons, technology is a fart.

At the beginning of the month, Man was not angry or annoyed, and said lightly: "You occupy this place and let your son play all the time, your son has played so many times, how the plane takes off and lands, do you understand?" ”

"Heh, don't you make a fuss here, do you know?"

"Of course I do." At the beginning of the month, Man looked at the waiting apron and said lightly.

Well?

What?

This beautiful woman actually knows how to operate an airplane?

The people who eat melons all look at the beginning of the month.

"When the aircraft takes off, by increasing the thrust of the engines, the aircraft generates enough lift to overcome gravity and get off the ground. This is atmospheric dynamics knowledge.

The asymmetrical shape of the upper and lower convex surfaces on the airfoil surface makes the air flow above faster and produces less air pressure, whereas the air flow below is slower and produces more air pressure, forming lift. It's aerodynamics.

The thrust generated by the engine propels the aircraft forward, lifting the aircraft off the ground, and the magnitude of the thrust is related to the weight of the aircraft, air resistance, and other factors.

An airplane needs to reach a certain speed for take-off, which is known as take-off speed. The take-off distance depends on factors such as the design of the aircraft, the load, the air temperature, etc. ”

The crowd was stunned.

What the woman said was all this, although they didn't understand it at all, but it sounded very professional.

The fat woman was also stunned.

This is too powerful, right?,I guess it's a female professor or a female doctor in science and engineering.。

Oh my God, she thought she was a junior.

It is true that people cannot be seen, and the sea water cannot be measured.

"Do you need me to explain how the plane lands?"
