Chapter 312: Far Ahead!

"What the hell!"

"Is this the invisible technology?"

"Four-elephant metamaterial!"

"Is this an American blockbuster?"

Even Yang Rubin, who had been exposed to it before, was dazed when he saw the full change in visual effects.

This step of final assembly is really the right one

This luster is really intoxicating

He and Lin Guangrong looked at each other and saw the joy in each other's eyes.

Lin Guangrong: "Zhou Rui participated in the assembly of the prototype throughout the whole process and personally led the team to overcome several process difficulties. The actual application of the Four-elephant metamaterial is more optimistic than the earliest assumption and has become very mature."

Four-elephant is awesome! Fu Rui is awesome! Zhou Rui is awesome!

Yang Rubin thought of "Northern Industry". Although it had obtained the authorization of "Fu Rui Technology" and had a full set of technology.

But without the participation of "Fu Rui Technology", or in other words, without the participation of Zhou Rui, the progress of large-scale manufacturing of the Four-elephant structure for use in ground and surface equipment cannot be compared with Rongfei.

This thing is really a thousand difficulties without Zhou Rui, but with Zhou Rui, it will soar into the sky.

The prototype crew outside the cabin door was much calmer. They had already tested the functions many times. Although they also cried like ghosts and wolves and were crazy when the whole machine turned on the "Four Elephants Stealth" for the first time.

Now the engineers looked at the people cheering behind the tower glass from afar, and said in their hearts: "I have never seen the world."

The display of the prototype is not over yet. It showed dynamic functions such as "canard adjustment" and "tail jet adjustment" in front of the tower, but compared with the appearance of the Four Elephants metamaterial, it was not amazing enough.

Finally, it has reached the most important stage, which is "test flight".

Mighty Dragon! Mighty Dragon! Of course, it can only be called a dragon if it flies into the sky.

With the order from the tower, the engine of the prototype roared. After Zhou Rui pointed out the problem, the adjusted AL-31 engine reached full blood state, and the achievement rate of various indicators exceeded 95%.

The test pilot took a deep breath, pushed the power lever, and the prototype began to accelerate sharply.

The roar reached the tower and the door behind. The engineers were not calm at this time. After all, no matter how many tests were done in the warehouse, they had never really taken to the sky.

Many people clenched their fists and clenched their teeth. Some people even dared not to look and closed their eyes.

The calmest one was Zhou Rui.

He was the tallest and had good eyesight. He stood at the front of the crowd, with his hands behind his back and a smile on his face.

He was calm and confident in the work he participated in.

He knew very well that this test flight would be a success, or a huge success.

This work that condensed everyone's hard work will eventually soar into the sky, and the actual data will bring greater surprises.

Because after the engine castration incident, his daily "engineering knocking" was used on the prototype, and he finally got the judgment of success yesterday.

The system gave this modified J-20 the following evaluation:

"Far ahead!!"

After accelerating extremely fast, the mirror-colored J-20 prototype with a full sense of science fiction suddenly climbed up, and rushed steadily into the sky with fierce air pressure.

On the tower and in front of the warehouse door, there was a burst of warm applause and cheers.

It's flying! It's flying!!

Yu Shu and Chai Lianjun jumped three feet high, hugged each other, and bumped into each other.

Wang De danced with joy and shouted, "Get up! Get up!"

Wen Hongqi's hand trembling problem came back, but this time it was excitement.

Han Ziyin was wearing a white coat, and her bright eyes were full of smiles.

On the tower, everyone was also clapping crazily, and Lin Guangrong, the "Director of Product Development Department", finally felt relieved.

The Air Force's leader was sweating all over, purely out of excitement.

A general who was born as a pilot hurriedly asked: "What is the take-off distance? Why does it feel so short?"

Lin Guangrong laughed: "With the new skin technology, the take-off distance of the J-20 is even shorter than when it was first designed. The take-off distance on the ground should be within 280 meters."

Due to its extremely high speed, the prototype quickly exceeded the visual range of the people in the tower. Many people took out their telescopes, but it was still difficult to capture it.

"Why can't I see it at all?"

Lin Guangrong proudly explained: "The mirror effect of the Four-Elephant metamaterial also has a huge advantage in naked eye observation. With the size of the J-20, it is difficult to observe it from 2 kilometers away."

Put it on the ground, even if the flight altitude exceeds 2,000 meters, the ground personnel cannot detect it with the naked eye. Although it is not a key function on the modern battlefield, it is also a pleasant surprise.

The changes brought by the Four-Elephant metamaterial are more than imagined.

But it doesn't matter. Although it can't be seen, the prototype soon flew back. The tower contacted: "How does the test pilot feel?"

The test pilot's magnetic voice sounded

"It feels very good, better than the performance of the simulation cabin. Now apply for a maneuver demonstration."

"Approved, good luck."

The prototype returned to the sky above the 919 factory, and then flew low, showing a "falling leaf rise"!

Although low-model aircraft can also perform this maneuver, it is still one of the good ways to test power performance.

This ace test pilot is very powerful. He went back and forth three times, and did "high G roller" and "broken S maneuver", which made everyone excited.

So far, the test flight has nothing to do with failure, but there are still two most important projects to do.

"Tower, this is the Veyron. All maneuvers have been completed. The fuel inventory is normal. Now apply for cruise test and stealth performance test."

The tower was silent for two seconds, and then said: "Approved, good luck to you."

The prototype passed over the 919 factory for the last time.

Then it accelerated with a "boom", leaving a sonic boom cloud in the sky, and the mighty Dragon's loud roar resounded throughout the earth.

The sci-fi-like fuselage disappeared into the horizon.

He will keep moving forward in the target direction to test the maximum cruising speed.

Moreover, you will pass by four radar stations along the way.

There are four radar stations, both traditional radars and the most advanced active phased array radars. They have all received instructions and are working hard to find this big bird from the sky.

This is the most intuitive test method for stealth performance. It is more effective and has more practical significance than using instruments to measure in the factory.

As the prototype accelerated, more and more information came back.

"The maximum speed has reached Mach 8"

"Has passed the first radar station, altitude 10,000 meters."

What? It has passed?

The people at a certain radar station looked confused.

When?

"Has passed the second radar station, altitude 12,000."

ah? Are we here too?

The staff at the radar station looked at the unresponsive display screen in confusion.

Are you sure your route is correct? Are you flying sideways?

"Has passed the third radar station, altitude 13,000 meters."

The 919 tower also received a series of messages, and everyone held their breath.

"We have passed the fourth radar station, the altitude is 17,000 meters, and the entire radar area has been penetrated. Please apply for return."

The receptionist at the control tower quickly replied: "Return approved"

The communication channel was temporarily quiet.

Everyone in the tower looked at each other in shock

You know, the engine field of the Republic is a bit stretched.

But in the field of radar, it has definitely surpassed the Bald Eagle and is the only advanced technology in the world.

Even if those previous-generation radar stations didn't make any gains, their most advanced active phased array radar didn't find any trace of the prototype.

This means that this plane

There is no one in the world

Low-point! Low-point!

No known interception means worldwide

Keep a low profile!

A great man is lying down!

A group of engineers outside the warehouse door were still straining their necks to look around. In fact, wherever they could see it, they had already flown far away.

Zhou Rui handed the maintenance order to an engineer and turned around gracefully.

"Zhou Rui, don't you want to read it?"

"It's early to come back, I'm going to have a drink of water."

"Entry task [Reputation], experience value +5, current progress (41/100)"

J-20, Flame Fang, Republic Veyron

With the wings of Zhou Rui, a butterfly, he was born one year ahead of schedule in his previous life, with a more powerful attitude!

This world will usher in more changes.
