This was the first time Dai Xiaomei had noticed it.
There was actually an academic atmosphere in his live broadcast room.
The fickle netizens finally weren't talking about random topics. Instead, they were talking about serious physics knowledge.
"You guys, when I'm streaming, I'm just talking about driving. When my dad comes, you pretend to be serious.”
Daizai looked at her fans in the livestream speechlessly.
"Then shouldn't you reflect on yourself?”
Li Changan said at this time.
“…………”
Daomei was instantly speechless.
She opened her big eyes and looked at Li Changan.""Dad, am I not your little cutie?”
"I'm watching your live broadcast recordings from before.”
"To be honest, I feel sorry for your mother," Li Changan said lightly.”
"Other people's sons and daughters are all walking hormones, but you've become walking steroids!”
Puff!
Li Changan's words made the little girl break down.
Meanwhile, the netizens in the live broadcast room all burst into laughter.
It was obvious.
Everyone was quite happy to see her deflated appearance.
"I'm dying of laughter!"
"I realized that father-in-law is also a little expert at scolding people.”
"As expected, scientists know how to chat.”
"President Dai has met his match."
"No tricks, my biological father!"
"Speaking of which, my father-in-law seems to be quite eloquent.”
"He's a real scientist. His IQ is there.”
"That makes sense."
"It seems to be true."
"Speaking of which, President Daze's recent livestream style seems to have become a lot more serious.”
"Hehe, she wants to drive, but she has to be brave enough to calculate.”
"You're right."
“………………”
Li Changan was very calm, not as excited as his fans.
He had no intention of rebuking his daughter. He was just trying to reason with her.
Although he doted on his silly little sister, Li Changan did not have many people who doted on their daughters.
What should be said.
He definitely had to say it.
"Alright."
Li Chang 'an saw that everyone was still mocking the silly little sister, so he smiled and said,""Since we've talked so much, I'll tell you another principle of the solid rocket.”
？？？
？？？
The little sister was dumbfounded.
His biological father!
This was a live broadcast room!
Do you think this is a small classroom?
"Dad, I'm broadcasting…"
The little girl complained helplessly.
"So what if it's a live broadcast?"
Li Changan glanced at her." Whether it's a live broadcast or something else, it has to spread positive things. I see that everyone is very happy listening to it."”
Dazed Little Sister opened her mouth.
Before she could refute Li Changan.
The special effects of the gifts had already started appearing on the bullet screen.
User White Tea Baby gifted the streamer a super rocket: Professor Li was right.
User Happy Princess gifted the streamer a super rocket: Uncle, please continue.
User Jun Wujoyan gifted the streamer's silly little sister a super rocket: Professor Li, I'm a physics major. You're so good.
F * ck!
Little Sister was speechless.
This slap in the face came too quickly, like a tornado. She had nothing to say.
Li Changan laughed and continued,""Another principle of a solid rocket is that the total area of internal combustion is proportional to the thrust.”
"There is a problem with this principle. Obviously, if the first burning hole in the middle of the grain inside the solid rocket is a right cylinder, then the further it burns, the larger the total area of burning.”
"In this way, the thrust of the solid rocket will increase as the combustion deepens.”
"However, most rockets or missiles require the greatest thrust when they are just launched.”
At this point.
Li Changan shrugged." Later, I thought of a way to change the long hole in the middle of the grain into a complicated rice-shaped or even snowflake-shaped shape instead of a simple cylinder. This way, the burning area of the rocket would be more balanced.”
He paused.
" But this doesn't solve the problem of dual pulse ignition and secondary combustion of the missile," he said helplessly.”
"The new design of the complex shape of the combustion hole in the solid rocket motor only solved the problem of a more reasonable rocket thrust curve, but it did not solve the problem of double ignition and double combustion of the solid rocket.”
" Because no matter how big or small a solid rocket is, once it is ignited, it can only be completely burned out. It is definitely not like a liquid-throttled rocket, where it will be passively ignited after it is extinguished halfway.”
？？？
？？？
At this moment.
A bullet screen suddenly caught Li Changan's attention.
User Jun Wouldn't it be fine if the solid rocket engine of a missile was made into two sections and the burnt part was thrown away like a large rocket?
It was obvious.
He was a military enthusiast and had some understanding of missiles.
Li Changan smiled and explained," The problem is, whether it's an ordinary or a larger dual-pulse missile. He maintained his perfect aero shape throughout the entire battle and did not miss a single segment. The entire missile ignited twice. They were all using the same jet at the end. In principle, any solid rocket that shared a single burner could not be reignited.”
After saying that.
He smiled proudly." Other than me, no one has figured out this problem."”
F * ck!
！！！！
！！！！
At this moment.
The entire live broadcast room fell silent!
