The wealthy stepmother became popular after her baby failed

There is also a large group of children around, a boy who is about [-] years old is operating, the plane really takes off and lands just like in a real airport.

Zhang Youchen wanted to try it very much, but the little boy didn't intend to stop at all, and kept playing for about seven or eight times.

Due to the limited time, Lin Jiamei finally couldn't bear it anymore and said to the boy: "This brother, can I let my brother play too?"

"I haven't had enough."

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

"What's wrong with my son playing with it several times? It's not from your house, so why don't you care about my son?" A fat woman came over and said loudly.

The tourists around all looked over.

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

Who knew that Zhang Youchen was just like taking some medicine, he had to wait and play.

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

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

The boy became compassionate, moved away, and said, "Why don't you play it once."

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

Lin Jiamei flushed with anger.

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

[This kind of person is selfish and only wants to take advantage, so disgusting]

[Lin Jiamei is too timid, if it's me, give her a slap]

Yue Yueman came over.

Since entering the science and technology museum just now, Yue Yueman has spotted a group of kindergarten wearing XX at a glance.

They should be some kind of institution outside the school. They specially bring the children in the class to visit. The leader is a staff member wearing a T-shirt with the words "Science and Technology Museum". He is a young man in his 20s, and there are some teachers and parents around him. , also wearing the same color T-shirts as the children.

Those children are about the same size as Doudou, and they may all be in the top class of kindergarten.

Yue Yueman walked over and said sweetly to the staff member: "Hello, my son is very interested in technology, but unfortunately I don't understand anything, can I trouble my son to accompany you?"

When the staff saw it, it was too beautiful!
Just like the girlfriend of his dreams.

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

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

So in just 2 minutes, Yue Yueman entrusted Doudou to a professional organization, and then she sat in the rest area, carefree.

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

Originally, she thought that Lin Jiamei would argue with that fat man, but who knew that Lin Jiamei was so cowardly, and she was blushed by others.

Yue Yueman couldn't get used to it.

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

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

Yue Yueman pulled Lin Jiamei aside, pulled Zhang Youchen closer to the boy, and said, "You have played enough, let the other children play."

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

The fat woman walked over with her buttocks in the air. She looked Yue Yueman up and down, and said angrily, "Who are you?"

Yue Yueman smiled faintly, "Who am I who needs to report to you? Let your precious son make way."

Yue Yueman's attitude undoubtedly angered the woman, and she released the classic saying just now, "This is not your family, even if my son plays for a day, you can't control it."

Yue Yueman raised her eyebrows, "Really?"

As she spoke, she pushed the boy away and stood by the console by herself.

"You, you actually pushed my son." The fat woman turned pale with fright, shouted and rushed over.

Yueman just blocked it lightly, and the woman could only flop about half a meter away from Yueman, and couldn't reach Yueman's body anyway.

The tourists around were stunned.

This woman looks so thin, but she is so strong, such a heavyweight person can't get close to her.

【Hahaha, Sister Man is mighty】

[I knew that my sister Man had to come forward for this kind of thing, and when I met such a thick-skinned person, I had to deal with it]

[But Yue Yueman is a bit too much, the child is fine, why does she push other people's child aside?]

[What's wrong with pushing, and I didn't push hard, can the brat just let it go?Yue Yueman is not his mother, there is no need to spoil him]

The fat woman started to swear, and Yueman pushed her three meters away without thinking.

"What are you? You have the ability to book the place for your son, let alone he is not your son, oh, I see, judging by your appearance, you should be a mistress, right? This is your lover's child?"

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

"Hey, what a wife and concubine love each other."

The tourists all gathered around, as if they didn't think it was a big deal to watch the excitement.

Compared with eating melons, technology is nothing.

Yue Yueman was not angry, and said lightly: "You occupy this place and let your son play it all the time. Your son has played it so many times. Do you understand how the plane takes off and lands?"

"Oh, don't play tricks here, don't you know?"

"Of course I know." Yue Yueman looked at the waiting apron and said lightly.

Ok?
what?
This beautiful woman actually knows how to operate an airplane?

Everyone who eats melons looks at Yue Yueman.

"When the plane takes off, by increasing the thrust of the engine, the plane can generate enough lift to overcome gravity and get off the ground. This is the knowledge of atmospheric dynamics.

The airflow on the airfoil flows through to generate lift. The asymmetric shape of the upper convex surface and the lower convex surface on the airfoil makes the upper airflow faster and the air pressure generated is smaller, while the lower airflow speed is slower and the air pressure generated is lower. Large, forming a lift.This is aerodynamics.

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

The aircraft needs to reach a certain speed to take off, which is called the take-off speed.Takeoff distance depends on factors such as aircraft design, load, and air temperature. "

The crowd stayed.

What this woman said, although they couldn't understand it at all, it sounded very professional.

The fat woman was also stunned.

This is too powerful, probably a female professor or doctor of science and engineering.

God, she thought he was a mistress.

It's really unbelievable, and the sea can't be measured.

"Do you still need me to explain the principles of airplane landing?"
