On the subway home.

Tang Rui sat on the chair and lowered his head.

In the eyes of others.

He was resting, and he might even have fallen asleep.

But in fact, he lowered his head just so that the people around him would not see the screen on the smart glasses.

At this time, he was designing drones.

The police's requirements for drone performance are actually not high.

It's just that the requirements for the performance of optoelectronic systems are a bit perverted.

This is not a matter at all for Tang Rui.

But here's the problem.

Optoelectronic systems are simple to solve, but what about other systems.

He couldn't build a drone for the police based on the performance of his drone.

Not at all.

Not to mention the excess performance, the price is certainly not cheap.

Although he did not calculate the specific cost of his drone, how much it would cost to build it with existing equipment.

But he is sure that its price is definitely not lower than that of the Pterodactyl 2 drone.

(Sold to the big dog Wing Loong 2 drone, the unit price is 2 million US dollars)

This price, the police can't accept it.

Therefore, he could only redesign one drone, keeping only the optoelectronic system, and all the rest were simplified.

Needless to say, the engine was directly replaced with a propeller.

The structure is simple, easy to maintain, and the leather is durable.

Needless to say, the aluminum alloy he just bought, this is not used.

The rest of the avionics system is also castrated, and the performance does not need to be the same as that of the military.

These configurations have been cut down, and prices have gone down like crazy.

It's easy to say anything about configuration.

Reduce some performance, replace some equipment, and you can take it out and use it directly.

The only thing he needed to do was to redesign the aerodynamic shape of the drone.

It is impossible for him to move the stealth design of the drone directly out.

Isn't that funny?

When did wanted criminals and criminals also have air defense radars.

Moreover, the stealth design requires sacrificing the aerodynamic layout and reducing the lift coefficient, which is completely unnecessary.

"The maximum curvature of the middle arc is 8.9%, and the maximum lift coefficient at the angle of attack is 12 degrees, which is 1.8......"

As Tang Rui's thinking turned, the design drawings on the screen continued to be enriched.

If someone in the know sees a drawing, he will know what he is drawing.

The most classic, but also the concave-convex wing with the highest lift coefficient.

This wing shape, without considering other factors, is definitely the most awesome lift coefficient.

Less than fifteen minutes.

Tang Rui drew a sketch of the entire body shape of the drone.

It looks a bit like a slimmed-down version of a civil airliner.

No way.

In the subsonic state, the aerodynamic shape of the civil airliner is the most stable and the highest lift.

"Xiaoyi, do you know why I placed the wings under the fuselage?"

Tang Rui looked at the sketch and asked Xiaoyi casually.

"Lower single-wing layout, ...... higher lift-to-drag ratio"

Xiaoyi immediately searched and sorted out a bunch of information according to his question.

But that's not what he wanted to know.

He just tried to see if Xiaoyi had made any progress in the past two days.

Unfortunately, nothing has changed.

The answer to the question is still so rigid.

"Very well, now that you know about aerodynamics, let's design the body of the sixth-generation aircraft."

“…… Xiaoyi, I don't understand how to design. ”

"If you don't understand, forget it, let's model this drawing in 3D."

"Okay, 3D modeling is underway."

When Tang Rui returned home.

The body model of the drone has already been made by him.

Don't think it's fast.

But any graduate of this major, designing this kind of classic body, or with the assistance of artificial intelligence, will be very fast.

This is not a creation, it is just a copy, and there is no difficulty in it.

Even the specific data is in the textbook.

"Xiaoyi, upload this model to 'Oriental Yufeng' and test the data.

Remember to delete the data when you're done testing. ”

"Okay, creating permissions, uploading data, building model, starting testing ......"

Tang Rui didn't care about Xiaoyi's test data.

Because the data is not important.

It's all a pneumatic layout that has been proven for many years and won't have any problems.

He wandered around the small courtyard of the villa, thinking about the layout of the workshop.

At present, this rented villa is more in line with his preferences.

The entire villa has a floor area of 386 square meters, with one basement floor and two floors above ground.

However there is also an attic and a large balcony above.

However, the attic, large balcony and small yard are all part of the free area and are not included in the construction area.

If I bought it back then...... Forget it, I don't want to do it.

At the moment, he is considering whether to renovate the workshop directly.

There is a plug-in called the system panel.

plus Xiaoyi, a semi-finished artificial intelligence.

He could have built a studio like Iron Man.

But the problem is, this villa is not his.

Bought this villa?

It feels a little small.

After all, Huawei's money has arrived, and he can buy a big villa.

Buzzing......

Just as he was thinking about whether to buy this villa, his phone vibrate.

You don't need to take out your mobile phone, the call number is directly displayed on the smart glasses.

Mr. Yu's phone number.

The money came.

"Mr. Yu, hello."

"Hello, Mr. Tang, I didn't bother you."

Mr. Yu, who was on the other side of the phone, directly called out his surname.

For this.

Tang Rui felt that it was normal, after all, he called yesterday and did not change his number.

For a company like Huawei, it is not easy to check his phone.

"No, I've just arrived home and I'm resting on the couch."

"It's good that you don't bother, if it's convenient for Mr. Tang, can you let us visit.

If it is not convenient, we have already booked the meeting room of the hotel, and Mr. Tang can also come to the hotel.

We mainly wanted to talk to Mr. Tang in person about image algorithms. ”

Boy.

No wonder I didn't call him until now, and everyone arrived in Jinling.

"It's convenient, you can come over directly."

After Tang Rui finished speaking, he reported the address of the villa to him.

Then he said a few polite words and hung up the phone.

Mr. Yu and the others are still at the airport.

I called and asked for his opinion.

From this also indicates.

They didn't check his address, they just checked the phone number.

The scale is very well handled.

Tang Rui calculated.

From the airport, you can get to him in about an hour.

The thought of the money from the sale of the algorithm can allow him to buy a villa and start a company.

His good impression of Mr. Yu in his heart was a crazy surge.

Mr. Yu came, and the money to buy the villa was there.

Mr. Yu is here, and the starting capital will not be a problem.

Mr. Yu is here......

He had to sell some tea and fruit or something, and he couldn't have nothing.

Come to think of it.

Tang Rui hurriedly got up and went out to buy something.

After all, it was sent to him for money.

Face must be given in place.
