I waited less than two minutes.

On the other side of the phone, an unfamiliar voice rang along with the murmur of signal transfer.

"Hello, this is the Air Force Management and Command Center."

"Hello."

Chen Yi repeated his request: "UAV application test flight, No. 0A01, No. 0A02."

“0A01...... Please determine the airspace where you want to test fly. ”

"Airspace?"

Chen Yileng paused for a moment, and then reacted.

This refers to the range of routes that you test fly, as well as the altitude.

"Penghai take-off, latitude and longitude E114,05,51.17,N22,38,18.79."

"After takeoff, the direction is north-west, passing through Gui Province, Yunnan Province, Hengduan Mountains, Himalayan ......"

"Height, less than 70,000 meters."

There was silence on the other end of the phone, as if asking for something.

After more than ten seconds, the voice sounded again.

"0A01, your test flight application has passed.

Please pay attention to the civil aviation route and do not stay too much in the civil aviation altitude range.

At the same time, it is forbidden to break through the sound barrier in the airspace below the kilometer. ”

"Thank you."

Chen Yi thanked him.

Hang up the phone and open the roller shutter on the side of the second floor.

Then move the multicopter drone and some signal equipment to the open balcony on the third floor.

By the way, I also moved an induction cooker and a small soup pot, and then took out noodles, fat beef, cut mutton beef, mushrooms and vegetables from the refrigerator, washed them briefly, and prepared to open a small stove while testing the drone.

knew that Chen Yi had the habit of staying up late from time to time.

These ingredients were all prepared by Qin Xiaoyu and put in the refrigerator, and at the same time changed regularly, so that Chen Yi could open a small stove by himself when he was hungry in the middle of the night.

Turn on the laptop, connect the signal antenna and control the rudder, etc., so as to facilitate external covering.

"Start taking off!"

Bring water to a boil.

Open the protective net of the balcony.

Chen Yi powered on the virtual helmet, activated the host function, and then put on a brainwave sensing headband, as well as immersive AR glasses adjusted into student glasses.

The mind moved.

Brain waves flashed.

Yikes!

A jet sound rang out from the second floor.

This sound is very obvious in the still quiet early morning environment.

Two seconds later.

Under the fuselage and at the tail of a plane, a blue glow slowly erupted.

Like a manta ray hitting a mosaic drone.

It was through the rolling shutter door that opened on the second floor, and flew out obliquely.

The width of the fuselage is more than 3 meters, which is already more than the width of the roller shutter.

If you want to come out, you can only come out by such an inclined angle.

"It seems that I have to change the venue when I am free.

In the current place, drones have been built, and it is difficult to get out. ”

Through the precise control of the ion thruster, Chen Yi controlled the sunset drone to fly out of the second floor and into the air outside.

The movable ailerons of the left wing are deflected.

Flatten the angle of the drone's inclination.

Then, a violent air flow and glow erupted from under the fuselage.

The entire drone took off into the air, took off vertically, and quickly came to an altitude of several hundred meters.

"This ...... It's an exaggeration. ”

When he came to the air, Chen Yi habitually turned on the infrared scanning function.

Before the sun rises and the temperature of the environment has not yet risen, determine the situation of life around you.

Avoid accelerating the drone later, causing damage or impact to the people around you.

But as soon as it was opened, a series of red dots were orderly distributed around his home, moving from time to time, which was projected into Chen Yi's retina through AR glasses.

For Chen Yi, who has lived here for several years and is already very familiar with the surroundings.

At a glance, it can be seen that the location of these red dots is all the key but passage mouths, high points, and lookout points around their homes.

"Am I already such a big guy?"

Chen Yi remembered that Professor Zhang said that the identity of the consultant was convenient for him to arrange some things reasonably, and he probably determined the identity of these people in his heart.

It is clear that these are professional protectors who have avoided becoming nuclear physicists in the Persian state themselves.

"Rotary detonation engines, three-combination scramjet engines, and formula models involving four-combination or even five-combination engines.

Including Yifei's ultra-high-energy batteries, high-end stress materials.

It seems, it seems...... It's really so awesome, it's enough to qualify."

Chen Yi counted the techniques he had taken out during this time.

The black technology used to engage in the machine by himself is not counted, but other technologies that have been disclosed and have not been concealed, this is already a peerless warrior.

What's more, his age is only 300 months.

Compared with the other more than forty, fifty sixty and seventy expert academicians.

No matter how you look at it, you can call yourself infinite potential.

In this case, it is also a very reasonable thing to increase the protection measures of 100 million points.

"No matter, anyway, I don't have to pay my salary, there is no close impact on privacy, just protect it."

Chen Yi shook his head, put this matter behind him, and began to control the drone to fly to an altitude of thousands of meters, and then turned on the engine at full power.

Call!

Early morning sky.

Suddenly, a bright light flashed.

Billowing fog swells around the drone.

Immediately after that, the speed of the drone increased dramatically.

Pierced through the sound barrier, rushed into the clouds, penetrated the clouds, and flew straight west.

A few seconds later.

The roar of the sound barrier being broken, the wind generated by the supersonic shock wave.

Along with the rising sun, it spills from the sky overhead.

But after a kilometer distance decay.

In addition to the summer sun, the roar and wind have long since become like a breeze.

"The drone began to charge.

Real-time charging efficiency, 5.57 kWh/12 hours per square meter.

It's the summer sun.

It had just broken through the clouds, and before it reached the stratosphere, where the radiation was stronger, and the sun was so fierce this morning.

In the stratosphere, the real-time efficiency at noon is 100% more than 20 kilowatt hours. ”

Chen Yi looked at the charging parameters projected by the AR.

After thinking about it, slightly reduce the speed of the drone.

Keep the speed in the subsonic range of 300 meters per second.

Avoid flying too fast and the sun can't catch up.

"Today, catch up with the success."

Observe for a while and make sure that the drone is flying normally and charging normally.

Chen Yi turned on the automatic flight program and turned off the AR projection in one eye.

Picked up the chopsticks, sandwiched a chopsticks of mutton, and put it in the pot.

Mix up some more sauces, open a bottle of pineapple beer drink, and start breakfast.

Half an hour later.

Chen Yi ate breakfast and threw the pots and pans aside.

I took two more plates of melon seeds and dried fruits, and turned on the AR projection.

While munching on melon seeds, I paid attention to the flight of the drone.

"The height is 8600, the speed is 312 meters per second, and the endurance is 32.6 percent."

"The flight data of this performance, as well as the engine power curve, also performed quite well."

"There is no data from the last test flight, so many small problems with the performance."

Check the flight parameters of the drone, as well as the recorded flight data.

Chen Yi looked at the bottom of the drone.

Powerful radar shooting function, clear capture of the street scene of the city below.

On both sides of the wide road, countless electric cars and Hongguang mini are shuttling back and forth.

One by one, the workers dressed in uniform were on their way to work.

Compared with more shirts, skirts, backpacks, computers, leather shoes and suits, it looks extremely delicate Penghai.

The city below is noticeably more austere.

On both sides of the street, breakfast shops are already open.

Through the oblique angle, the lens of the drone can clearly capture the signboards of these shops.

All kinds of powders.

Snail noodles, Guilin rice noodles, old friend noodles, dry fishing noodles and so on...... It accounts for more than half.

"It's time to Liucheng."

"No wonder, so many rice noodles."

Chen Yi looked at these dazzling food signs, and felt that he had just eaten a full stomach, and he was a little hungry.

"Next time, we must build a functional module for the drone that can sense the taste, and then cooperate with brainwave technology to taste food remotely and virtually!"

Look at it for a while, and take one picture after another.

Chen Yi muttered in his heart and pulled up the drone.

It accelerated along the basin of the Xijiang River, rushed straight to Yunnan Province, and flew towards the Hengduan Mountains.

It's just that Chen Yi, who is flying to comprehend the great mountains and rivers of the motherland and feel the smell of urban folk incense.

I don't know.

Air Force Management Command Center.

A group of people looked at the positioning signal moving at supersonic speed on the screen, and then compared it to the empty and blank radar detection interface next to it.

All of them couldn't help but fall silent.

Some of them couldn't help but have a ridiculous thought in their hearts.

This radar, fake, right......
