Tang Rui didn't know that the people from the military had already come to him.

He is also accelerating the drone.

Today he will definitely test the maximum speed of the drone.

As for the issue of flying out of the prescribed airspace.

He can't be blamed for that.

Kicking the accelerator down, Biao was too fast to react.

And there was a little bit of a problem with the communication system.

Anyway, there are many reasons to explain, in short, it is just a sentence, not intentionally.

The drone continues to accelerate.

When the wings are turned on at supersonic cruising, they are already closed to the fuselage to reduce drag.

"it...... Brother Rui, there won't be a problem with this speedometer, is this Mach 2.2 real? ”

"What, Mach 2.2, are you kidding?"

"it...... Mach 2.3 is too much in acceleration. ”

"Brother Rui, are you a rocket modification?"

"I'm about to enter the heat barrier, can the body withstand it?"

"Mach 2.4 is about to enter the heat barrier."

At this time, there were more and more people around, but everyone stopped talking.

What the thermal barrier represents.

Their group of aircraft design students know better than anyone else.

In the history of human aviation, there are only a few aircraft that can really break through the thermal barrier, and they can be counted on one hand.

If Tang Rui succeeds today.

Then his drone can be ranked among the top few in the world in terms of speed.

If you talk about reconnaissance drones alone, it is the second in the world.

The number one is Wuzhen-8, after all, the speed of Mach 6 is not so easy to break.

Tang Rui is not sure now whether his drone can exceed Mach 6.

"it...... Reached Mach 2.5. ”

"Awesome...... Enter the thermal barrier area. ”

"At this speed, the camera can see the red light."

"Mach 2.6, still accelerating."

When the drone reached Mach 2.5, the crowd around it boiled.

At this time, no one was playing model airplanes, and they all ran behind Tang Rui and stared at the screen.

This supersonic first-person perspective looks quite exciting.

When a warrior drove into the stadium, no one noticed it.

A middle-aged man in a military uniform got out of the car and came to the back of the crowd.

When he saw the data on the screen, the pupils in his eyes shrank.

The whole person became serious.

Then, he took out his phone and sent a few messages.

This includes the speed, direction and location of the current flight of the drone.

Less than a minute.

In Anhui Province, one radar station after another received an order from the Eastern Theater.

The radar is turned on at full power for five minutes and reconnoiters the airspace in the southeast direction.

Five minutes later, the radar scan will be reported.

After the message was received by various radar stations.

The radar is turned on as soon as possible, and it is turned on at full power.

Moment.

In the villages and towns around the radar station, the mobile phone signal disappeared directly.

In the blink of an eye.

Five minutes passed.

Various radar stations began to report on the situation.

"According to the report, none of the eleven radar stations in Anhui Province found any abnormalities."

"Okay, I got it."

The person in charge of the command center, after listening to the summary message from the radar station, nodded and did not say anything.

But after he finished speaking, he directly picked up his phone and sent a message.

The other side.

Around the rostrum of the stadium, everyone was also very excited.

Because of this time.

The speed of the drone has reached an astonishing Mach 4.2.

It's still picking up speed, but it's slow.

Even if all the fuel is burned, it will not add Mach 4.5.

For such a speed.

Tang Rui was already very satisfied.

If you strengthen the engine a little more, you will definitely be able to fly faster.

When the time comes.

It would not be a dream to surpass the Wuzhen-8.

Looking at the oil data on the screen, he directly pulled down the throttle valve.

No way.

It's too fuel-intensive to keep the afterburner on.

It's only been a long time since the flight, and less than half of the fuel remains.

If you keep driving the afterburner like this, you really won't be able to fly back.

It's still fast.

Tang Rui turned on ground scanning and shooting, wanting to see the shooting effect of the photoelectric system at this speed.

Brush!

A photo appears on the screen.

As the photo continues to zoom in, the cattle and sheep on the prairie are clearly displayed on the screen.

"Is this the shooting effect?"

"it!"

"It's no better than a spy satellite."

"This shooting effect, Brother Rui, you want to go to heaven."

"Brother Rui, let's be honest, did you steal the drone from the military laboratory?"

"This speed, this shooting effect, is too rebellious."

The people around you, you and I said it one by one, and every sentence said to Tang Rui's heart.

Although he didn't say it.

But the corners of his mouth turned up and his eyes narrowed all showed that he was in a very good mood.

"Now that the speed test is complete, let's start testing the limit height."

After Tang Rui finished speaking, he pulled up the joystick and controlled the drone to take off.

Previously, the drone flew at an altitude of 12,000 meters.

Although this altitude is already high, it is far from reaching the limit of the drone.

It was at this time.

A warning sign suddenly appears on the screen.

Tang Rui clicked on it and took a look.

It was the fighter that was spotted in front.

Enlarge the image.

"This is the J-16?"

"Hit a fighter jet."

"It's refueling in the air."

"Brother Rui, let's go over and take a look."

"Don't even take pictures, it's a military secret."

"Everyone is from Southern Institute of Technology and China Southern Airlines, and they all understand the confidentiality issues."

"Just get over it, don't talk nonsense."

In-flight refueling is not a top secret, plus he also wants to see the J-16 up close.

So after a reminder, I controlled the drone and flew over.

Turn on afterburner.

Less than two minutes.

The drone came to the side of the J-16 fighter jet that was refueling in the air.

Tang Rui deliberately turned off the detail enlargement of the optical equipment, and then asked Xiaoyi to put a mosaic on the front of the J-16 cockpit.

So.

From the computer screen, everyone can only see the J-16 refueling in the air, and nothing else.

Except that the distance is a little closer, it's the same as watching the Air Force propaganda film.

But seeing it with your own eyes, there is still a big gap between watching the video.

"The aerodynamic layout of the Super Flanker is so beautiful."

"Appearance is combat effectiveness."

"Look at the wingtips of the wings and the pods hanging under the wings, this is the J-16D."

"it...... I found those pods, and I thought they were missiles. ”

"Your missiles are square, I didn't see the wingtips are different, it's also a small pod."

Just as everyone was watching, a red alarm suddenly began to flash on the screen.

"It's been locked by radar, please get out as soon as possible."

Tang Rui saw this alarm and shook his hands in fright.

Finished.

It was too close to be discovered.

This is no joke.

Drones without air defense identification codes also fly to the fighter jets to watch people refuel.

That's really going to be knocked down.

It's not stealth design.

That's right.

It's stealth design, yes.

But stealth also has a limit, and he was too excited to see it just now and forgot about it.

In the case of this kind of radar sticking to the face, as well as infrared locking, no stealth design is useless.

Tang Rui did not hesitate, pushed the throttle valve, and accelerated the slide.

Don't run anymore, wait to eat the bomb.

The J-16D, which had finished refueling, also turned on the afterburner at the same time and caught up.
