My granddaughter gave me a mecha for her birthday, and the scientific community went crazy

The ten carriages that were originally parked on the railway tracks rose up from the ground and floated to a position more than two meters above the ground.

Professor Liu and others in Car No. [-] were shaken.

Haven't responded yet.

[The wing nest fan starts working, the current thrust is 423KN]

[Canglong, attack! 】

A fierce acceleration was applied to the fragile body.

The body was glued to the seat, and the strong inertial acceleration almost shook everyone's intestines out.

The Canglong transformed into a giant silver-white steel dragon, let out a shocking dragon roar, flew close to the ground, and disappeared into the valley.

In the wilderness, the giant steel dragon galloped quickly.

Professor Liu leaned back in his seat blankly, not knowing what to say.

The whole old face is numb.

His chin was trembling slightly.

It seemed like he had something to say, but also like he couldn't say anything.

The situation we saw before us could no longer be thought of in terms of a train.

The previous emergency escape mode was very exaggerated, but this one is even more perverted!

Some people say that trains don’t run slowly, they fly low!

The results really came true!

I'm not just flying now! !

Xiao Lin and Xiao Liu in the back were also shocked and expressed that they had lost control.

Xiao Lin exclaimed in surprise,

"My old joke!"

"As expected of the Soryuu!!"

Xiaoliu even shouted so loudly that his throat broke.

"Mama Mia!"

"If I tell my cousin that I have ridden on a flying train, she will give me a free gift of 5 yuan!!"

"I won't marry for less than ten thousand yuan!!"

Xiao Kun's handsome face turned red and he shouted,

"Dude, if we sing and dance in this flying carriage, it will definitely set off a wave of hot searches!"

Professor Liu rolled his eyes at Xiaokun.

"Everything we saw and heard on this train will be kept confidential. When we are done, you will all sign a confidentiality agreement!"

Xiao Kun was stunned and his mouth twisted.

After practicing for two and a half years, I was just waiting to become famous. Is such a good opportunity gone? !

"magnetic--"

The sound of the airlock door opening sounded.

Xu Fan walked out of the passage in front of Car No. [-].

Tang Shiyun followed.

"Professor Liu, dear tester friends, hello!"

Professor Liu took two steps forward and shook hands with Xu Fan.

Both of them are top scientific research talents. Although they are very different in age, they can hit it off immediately.

"Academician Xu, the Canglong you developed is really too powerful!"

"Many functions are unheard of. Let alone Xia Guo, even if you look at the whole world, they are unique!"

The moment Professor Liu saw Xu Fan, the excitement he had just suppressed surged again.

He was very excited when he saw Xu Fan.

He said pointing to the floor of the carriage.

"Not to mention anything else, the ground-effect lift engine under this carriage alone is enough to lead the world for decades!! Old man, I have been thinking about this for a long time, but I just can't figure it out!"

"Whoa!"

Xu Fan said bluntly,

"These lift engines are nothing. They are just ordinary ground-effect aircraft with a little more oil and vinegar."

"To put it simply, it is to use the upper and lower pressure difference to create a strong lift-to-drag ratio!"

While Xu Fan was talking, Xiao Lin, Xiao Liu and a group of testers all gathered around.

Tang Shiyun also looked serious and concentrated.

Everyone knows that there are not many times when you can hear Academician Xu impart knowledge. It may be the only opportunity in this life!

It must be held firmly.

Perhaps a word from Academician Xu can put them ahead at the starting line!

Everyone's faces were filled with nervousness and excitement.

A pair of eyes, either clear or old, stared closely at the young scholar in the center.

Xu Fan paused slightly mid-sentence and glanced around.

Seeing everyone's support, I can only say a few words.

He continued,

"However, conventional ground-effect aircraft still require some special fluid mechanics shape design."

"My design is unconventional. I made an annular opening on the nozzle of the engine, which is slightly similar to a Möbius strip."

"This can maximize the lift in the effective space!"

"If I say this, you should understand!"

Xu Fan looked around with a smile on his face.

Xiao Lin, Xiao Liu and others all looked a little confused.

What does this say, who am I, where am I, what do I do?

Seeing everyone's expressions, Xu Fan knew that maybe everyone was too young and had insufficient knowledge in this area.

So he turned his attention to Professor Liu next to him.

"Professor, maybe there are still some details that you can't understand or integrate. After you finish, you can tell us more when you have time!"

Professor Liu's mouth twitched twice.

For a moment, I was speechless.

A bit shameless.

Not to mention Xiao Lin and the others, even he, the teacher, looked confused!

The first two sentences are somewhat familiar, but the next few sentences have no idea what they are talking about.

He was just thinking about how to say this.

At this time, Tang Shiyun next to her suddenly said,

"Xiaofan, is the annular opening you just mentioned applied directly to the fan blades of the outer duct?"

Xu Fan's eyes lit up, he nodded, and even wanted to give Tang Shiyun a thumbs up.

"In a word!"

"That thing has a huge effect on improving the external ducted fan, directly reducing the duct ratio to only 0.1!"

"This is also why he can bring such amazing lift!"

Tang Shiyun's eyes shone with a vague understanding.

He felt that he had grasped something important, but as long as he thought deeply about it, more question marks would arise in his mind.

My little brain is about to shut down.

Professor Liu on the side could no longer keep up with his train of thought.

He simply chose to give up. It wasn't that he didn't live up to expectations, it was just that he didn't have enough brainpower.

Let’s wait until everything is over and study it bit by bit.

It is probably not something that humans can do to understand the core principles of this big guy with just a few words or a few hours of lectures.

Suddenly, Professor Liu thought of something and looked at Xu Fan fiercely.

"Academician Xu, you and Nvwazi are here. Who is driving the train now?"

"unmanned."

"No driverless train!! Train!!?"

Professor Liu was startled.

He grabbed the seat next to him and his old eyes widened.

“The ground effect flying train can also be driverless??”

"Of course!"

Xu Fan explained,

"It is probably based on the trinity of cameras, radars, and ultrasonics for environmental perception, path planning, and control execution."

"This shouldn't be too difficult!"

Professor Liu shivered suddenly.

Go back a little.

Can't talk anymore.

Hear this plausible?

Even if the train can fly, it still drives itself! !

There is also the matter of the deformation of the locomotive, which we dare not say, let alone ask!

Not a human being! !

Xu Fan took out his phone and took a look.

"We are about to reach our destination. I'm going to see where to stop the train. Remember to hold on and hold on when it slows down."

"Okay, Academician Xu, you go about your business!"

Xu Fan and Tang Shiyun returned to the cab and put on their holographic helmets.

Through the navigation display on the holographic helmet, it will arrive in 2 minutes.
