Looking at the Xuannu Aerospace Fighter on the platform, which looked like a black sword hilt, Lin Yu couldn't help but say in admiration: "Yes, this livery design is very good, and it perfectly integrates the future sci-fi style." ”

Hearing Lin Yu's praise, everyone present smiled.

"Mr. Lin, this is a painting designed by Fuxi, there are currently two sets, and one is red and blue."

Zhao Yu waved his hand and let the artificial intelligence release the holographic projection of the second set of livery designs.

The next second.

A red and blue, 3D holographic projection virtual fighter appeared in the air.

It's different from the first set.

This second set of Xuannu aerospace fighters does not have a cockpit, not even a seat, and is unmanned in the true sense.

After a brief glance, Lin Yu asked, "All of Xuannu's systems should have been tested, right?" ”

"Yes, it's almost the first flight now."

Zhao Yu nodded.

"So what are you waiting for, let's get started."

Lin Yu ordered.

Hearing this, Zhao Yu beckoned into the distance.

Soon, a middle-aged man in a black special combat uniform walked over, brushed it, and saluted everyone.

Then, he looked at Lin Yu and said with a solemn expression: "Mr. Lin, hello, I am the first pilot this time, Xu Zhen, and it is an honor to be able to fly the Xuannu Aerospace Fighter." ”

"Hello, Comrade Xu Zhen, please get on the plane."

Lin Yu smiled slightly and said.

Xu Zhen saluted, turned around and walked towards the Xuannu Aerospace Fighter.

The engineers sprang into action to carry out the inspection.

Ten minutes later.

"The force field drive system is normal!"

"Variable cycle engine is normal!"

"Everything is ready!"

One report after another rang out.

Lin Yu looked at Zhao Yu, nodded slightly, and signaled that he could start.

Zhao Yu did not hesitate, and raised his voice: "Open the skylight and prepare to take off!" ”

The voice fell.

The tail of the Xuannu Aerospace Fighter, which was originally stationary, suddenly lit up with a faint white light.

The white light converged at the jet port at a terrifying speed, and countless light particles were spinning at extreme speed, like two deep white holes.

Splendid and magnificent.

At this time, the relevant feedback data also appeared on the control panel.

"The power system is good, the energy output is stable, and the variable cycle engine and force field drive system can be started."

"The engine engine and force field drive are starting."

"Three!"

"Two!"

"One!"

"Startup complete!"

As the countdown ended, a small voice suddenly sounded.

Buzz!!

The next moment.

The white light seemed to have reached some kind of critical point, and suddenly burst into a blazing light.

Immediately after, a powerful burst of energy burst in.

The space around the Xuannu Sky Fighter seemed to be distorted, and it began to become a little blurry.

Obviously, this is caused by the forced change of the surrounding magnetic field by energy.

This sudden electromagnetic change spread almost instantaneously and swept the spot.

For a while, the hair on everyone's body stood up, and they all enjoyed the feeling of static electricity all over their bodies.

"It's a big formation."

Zhao Yu said with some horror.

The force field drive device was completely activated, and the Xuannu Aerospace Fighter slowly suspended in the air, standing still.

"Everything is working fine with the system."

The Chief Engineer promptly issued a report.

Seeing this, Lin Yu picked up the communication headset and asked, "Xu Zhen, how do you feel?" ”

"It's not bad, but I have the illusion that my body is very light, and I don't fit in."

Xu Zhen's voice came out of the communication channel.

"It's okay, this is a normal reaction after the force field drive system is activated, because the gravitational force of you and the Xuannu fighter has been canceled out, so you will feel very light."

Lin Yu smiled

After explaining, he looked up at the window above that revealed the blue sky, and said, "Okay, you can prepare for overload, now that the skylight has opened, let's go." ”

"Yes!"

Xu Zhen took a deep breath and began to increase the power of the force field drive system.

Soon, the Xuannu Aerospace Fighter slowly floated into the air, followed the window, and left the secret base.

Now the power of the Xuannu fighter is not fully turned on, only the force field drive device is maintained.

Because if the variable cycle engine is activated inside the secret base, the astonishing acceleration brought by a split second will compress the surrounding air to an incredible degree.

This is equivalent to having a fighter jet break the sound barrier at such a close distance.

The consequence is that except for Lin Yu, everyone at the scene will die on the spot nine times out of ten.

Therefore, Xu Zhen controlled the Xuannu Aerospace Fighter and came to the outside of the secret base, and continued to rise, standing at an altitude of thousands of meters.

At this time, the surrounding airspace has long been emptied for martial law.

Under the blue sky and white clouds, only the Xuannu Aerospace Fighter was suspended in the air, silent.

Inside the main control room.

Lin Yu and others can use the signal sensor on the Xuannu's fuselage to locate it in detail, so that it can come back from outer space.

Otherwise, without coordinates, Xu Zhen would be easily lost in the universe.

Of course, the Xuannu fighter is equipped with an environmental control system.

It includes multiple modules such as air supply control, cabin pressure control, temperature control, humidity control, etc.

Not only can the temperature be adjusted independently, but also a series of indicators such as air supply, pressure, and humidity in the cockpit can be adjusted to keep the driver's environment stable.

Therefore, even if Xu Zhen stays in outer space for a while, there will not be much of a problem, at most, he will starve to death.

"Mr. Lin, I'm going to start."

Xu Zhen said slowly.

Hearing this, Lin Yu hurriedly walked out of the general control room and rushed towards the outside of the secret factory.

Behind him, Zhao Yu and the others hurriedly followed.

Soon, Lin Yu and the others came to the spacious venue.

Here, you only need to look up to see the Xuannu Aerospace Fighter suspended in the sky.

The line of sight is very clear.

"Mr. Lin, give."

Next to him, Zhao Yu handed over an earbud.

Lin Yu took it and put it on, and then explained to the people behind him: "Everyone put it on, there will be a lot of movement later." ”

Everyone was stunned, and hurriedly took it from Zhao Yu and put it on.

It didn't take long for everyone to put it on.

in the sky.

Xu Zhen started the force field drive device and the variable cycle engine with all his might.

And at the moment of starting, the tail of the Xuannu Aerospace Fighter burst out with a blazing blue torrent!

Countless brilliant light particles go crazy in the sky***.

The surrounding space was directly distorted by the terrifying power, forming a huge white vortex.

Rumble!

With a thunderous explosion, a huge sonic barrier cloud suddenly appeared.

And, not just a sound barrier cloud.

Instead, a series of sound barrier clouds are combined, as if forming a sound barrier cloud channel, straight into the sky!

In the eyes of Lin Yu and others, the Xuannu Aerospace Fighter disappeared into the air almost instantly.

Then, as if the sky had been torn apart, it left behind a clearly visible trail of a sound barrier cloud, and this trace spread all the way to the end of the field of vision, like a cloud ladder!

At the same time, it was only after two or three seconds that a loud sonic boom rang out in the sky.

The rumbling sound of the explosion, like a bomb exploding next to the ear, was very shocking.

For a while, everyone's faces turned a little pale.

"Good fellow, this movement is too big!"

Zhao Yu said with a pale face.

The researcher next to him nodded in agreement.

"This speed is really terrifying, it starts at the speed of sound, if it is on the battlefield, if the soldiers around you are closer, you have to be shocked to death by the sonic boom."

"Yes, no matter how fast the J20 is, compared with the Xuannu Aerospace Fighter, it is simply too far behind, just now I felt a flower in front of me, and as soon as my ears exploded, the Xuannu was gone."

"I don't know where the Xuannu is now, shouldn't she have left the earth?"

"It shouldn't be so exaggerated, according to the design data of Xuannu, its speed in the atmosphere is 1,700 meters per second, and it should still be in the earth."

There was a lot of talking.

Lin Yu took off the earbuds and said with a smile: "The maximum speed of the Xuannu in the atmosphere is only 6,000 kilometers per hour, which is barely okay. ”

"When the Xuannu reaches space, its speed will reach 11.2 kilometers per second, which is the real top speed."

"11.2 kilometers per second?"

Hearing this outrageous data, Zhao Yu couldn't help but be secretly speechless.

Lin Yu smiled and walked towards the general control room.

Physicists divide the Earth's atmosphere into a total of.

They are the troposphere, stratosphere, mesosphere, thermosphere, and outer atmosphere.

The outer edge of the stratosphere is the maximum extent to which an aircraft can fly on air support.

Therefore, the distance from the earth to space is only 300 kilometers in total.

Above 300 kilometers is the orbit of the satellite, and further up, it is the orbit of the planet.

According to the calculation of the maximum speed of the Xuannu in the atmosphere, it only takes two minutes at most to reach space directly.

If it is extremely fast in space, it will be even faster, and it will only take 30 seconds to fly directly to the outer atmosphere.

Soon, Lin Yu and the others returned to the general control room.

"Xu Zhen, how are you doing now? Is there anything wrong? ”

Lin Yu contacted Xu Zhen in the communication channel.

However, after Lin Yu finished speaking, there was no response in the communicator.

"Mr. Lin, what's going on, shouldn't it be the Xuannu who has a problem?"

Seeing this scene, Zhao Yu asked a little nervously.

And everyone at the scene was also worried.

You must know that this is the first test flight of the Xuannu Aerospace Fighter.

Before that, there was no precedent in the world for a fighter jet to fly into space.

In addition, the environment in space is very harsh, and if there is any system failure in Xuannu, it will be a big problem.

The more I thought about it, the more solemn the expressions on everyone's faces became.

In the gradually serious atmosphere, Lin Yu said calmly: "Before the test flight, we have already tested Xuannu, and the engineers have not found any problems, so don't scare yourself." ”

"As for why there is no communication on Xu Zhen's side, I think it's probably because of the delay in communication."

"Communication latency?"

Everyone was stunned and a little confused.

"That's right, because we have captured all the communication satellites, Xuannu's artificial intelligence system will automatically switch, and switching communication and transmitting information will be delayed due to distance."

Lin Yu explained unhurriedly.

"Mr. Lin, do you mean that Xuannu has now arrived in outer space, and there is a communication delay?"

Zhao Yu quickly reacted, with an incredulous expression.

Boy.

It's only been a long time.

I'm afraid the bell won't be yet.

The Xuannu has already run to a place where there is a delay in communication?

It's also too sci-fi!

Just when Zhao Yu sighed.

In the communicator, a signal from the Xuannu suddenly appeared.

Xu Zhen's voice was finally transmitted back from the distant outer space.

It's just that because of the distance, his voice is very noisy.

"Mr. Lin, everything is normal on my side."

Hearing this answer, everyone at the scene breathed a sigh of relief and a smile appeared on their faces.

Lin Yu asked, "Then where are you now?" ”

After another ten seconds or so, Xu Zhen's voice came back, and said, "Mr. Lin, I have now completely departed from the outer atmosphere of the earth and arrived

Space in the truest sense of the word. ”

"I'm right now, right in the middle of the Earth and the Moon."

"According to the route planning of artificial intelligence, it only takes me about 40 minutes to reach the surface of the moon directly."

As soon as these words came out, everyone present was a little shocked.

"It only takes more than forty minutes to get from the Earth to the Moon?!"

"How is this possible! It seems like only six or seven minutes have passed since I took off just now! ”

"Even if you add these minutes, it's only about a minute, and you can get to the moon in less than an hour? That's too fast, isn't it? How far away is the moon? ”

"I remember it was more than 380,000 kilometers."

"Didn't Mr. Lin say just now, Xuannu's top speed is 11.2 kilometers per second, converted to Mach, that is 33 Mach, that is, 40427.64 kilometers per hour!"

"Oh my God, this is too exaggerated, we can take the high-speed train for more than an hour!"

Everyone exclaimed, their faces covered with disbelief.

Meanwhile.

In the desolate endless starry sky, the Xuannu Aerial Fighter turned into a white light and was flying at extreme speed.

Due to the high flight speed, the surroundings of the Xuannu fighter were covered with many high-energy particles.

These high-energy particles, which reached escape velocity, formed a bright phenomenon surrounded by particles on the fuselage of the Xuannu fighter.

From a distance, it looks like a glowing white sword hilt flying in space, looking shiny and cool.

However, cool is cool, but the driver Xu Zhen is not comfortable now.

Although Xuannu herself has a super buffer system, this incredible speed still brings a lot of pressure to Xu Zhen.

It can be said that he is now suffering from an overload of about six to seven gi's overload overall.

In general, the limit of what a healthy average adult male can tolerate is not more than 6 to 6.5 G.

And the able-bodied athlete will generally fall into a coma at 7.5G.

Only aerobatic pilots who have undergone long-term training, or astronauts, will be able to reach 9G with their extreme G-value.

But none of them will exceed 12.0G.

Because 12G is already the limit of human beings at present.

In the case of 12G, even an aerobatic pilot will be directly unconscious in 1.5 seconds.

As for Xu Zhen, he is an ace pilot, and an overload of six to seven G's can still be easily withheld.
