Black technology, starting from daily check-in

Above the 3000-meter altitude of the exhibition.

The Eagle Fighter J20, which was originally flying straight into the sky in the shape of a sharp sword, slowly turned its direction and dived towards the bottom of the exhibition at a high speed.

Not only that, j20 is still in the sky, performing various flying stunts.

Sometimes it is like a fallen leaf, swaying erratically and falling from the sky, with elegant and beautiful movements.

Sometimes it looks like a cobra, standing directly on the high-altitude parallel horizon, forming a posture with the tail in front and the nose behind, just like a cobra with its head raised.

Seeing the J20's various difficult flight stunts in the sky, all the military fans under the outdoor exhibition immediately shouted excitedly.

The mobile phones and cameras that shoot videos on the j20 didn't stop for a moment, and they all followed the flight trajectory of the j20 firmly.

"Where is this, the fun has just begun."

Li Gang, who was about 1000 meters above the exhibition, smiled slightly after feeling the cheering scene below.

As an ace pilot, he could feel that the performance of this ws15-loaded fighter hadn't been fully utilized yet.

It can be said that the current j20 has not yet started to exert its full strength, and the previous ones were at best jogging.

Thinking of this, Li Gang instantly increased the thrust to the end without hesitation.

next second.

Accompanied by the sound of thunderous explosions resounding through the sky, the two ws20 engines behind the tail of the j15 began to output full power explosively!

"Boom, boom, boom, boom~~!!!"

Amidst the huge rumbling sound, j20 dragged its fiery red flame tail, and instantly rushed vertically into the sky at a speed visible to the naked eye!

This time, the speed of j20 is several times faster than before!

So much so that beside the fuselage of the j20, there appeared a cloud of white sonic booms that looked like an upside-down bowl!

And with the huge sonic boom coming from the sky, the atmosphere of the outdoor exhibition reached its peak!

"Fuck! Breaking the speed of sound! Breaking the speed of sound!!"

"Nimma! Could this be afterburner? This speed is too terrifying!"

"Fart! You thought it was before, but now with the performance of our ws15, we can reach supersonic speed even without afterburner!!"

"That's right! Do you think the two ws35s with a thrust of 15 tons are nothing to eat? Supersonic speed doesn't matter if you have hands!"

"Grass! So handsome! My body is shaking with excitement now!!"

"This is the romance of a man!!"

Excited cheers erupted at the scene.

You know, this is the first time that the j20 can break through the speed of sound without turning on the afterburner in front of the public.

After all, although the j20 was a supersonic cruise fighter in the past, at that time, only afterburner could break through the speed of sound.

It is precisely because of this that many military fans are often ridiculed by netizens from Western countries.

However, it is different now.

As the saying goes, Feng Shui turns around.

With the birth of the ws15 engine, all military fans this year will probably go completely crazy on the Internet.

Amidst the excited discussions among the crowd, Li Gang manipulated the J20 to climb rapidly, leaving behind clearly visible sonic boom clouds in the sky.

It wasn't until the altitude of about 5000 meters that the j20, which had been climbing extremely fast, finally stopped.

"Report, I request to turn on the afterburner state!"

In the cockpit of J20, Li Gang said to the communicator with a little excitement in his tone.

The afterburner state refers to the process in which the thrust of the engine exceeds the maximum working state in a short period of time.

If you use the terminology of the game, it is to start the super nitrogen acceleration again on the basis of the original nitrogen acceleration in the flying car!

"Agreed, this time the afterburner state lasts for 10 minutes, you kid opened the fly for me."

Soon, a hearty voice of a middle-aged man came from the communication channel.

"Roger that!"

Hearing this, Li Gang raised a smile on his face, and immediately turned on the afterburner state!

"Boom, boom, boom, boom~~!!!"

The huge explosion resounded through the sky again, and the afterburner state of J20 was instantly activated.

For a moment, the j20 fighter jet in the sky seemed to be making a space leap, and shot towards the extreme distance at an incredible speed!

at the same time.

The original fiery flame tail behind the j20 has directly turned into a purple Mach ring with a length of three or four meters, which looks very cool and sci-fi!

And this terrifying speed also turned the air in front of the j20 fighter jet into a wall of white clouds.

However, this white cloud wall was directly pierced by the fully fired J20 fighter jets!

Therefore, in just an instant, the J20 with its afterburner turned on disappeared in front of everyone.

Seeing this scene, everyone under the outdoor exhibition was stunned.

"This... this speed is too outrageous! I disappeared in the blink of an eye! I have such a big J20!!"

"The afterburner is turned on! This fucking is definitely on the afterburner! If I don't turn on the afterburner! I'll just stand upside down and drink water!!"

"Hey, this afterburner is too strong, it's really exaggerated."

"Hahaha, this is the true strength of the j20! The j20 is awesome!"

After regaining consciousness, many military fans were shouting and venting their excitement.

In this state of afterburner, the j20 can reach a speed nearly twice the speed of sound. This speed is simply crazy!

Ten seconds later, j20, which disappeared from everyone's sight, reappeared.

This time, the j20 is still the same, starting to climb vertically from about 1000 meters above the outdoor exhibition.

However, because the afterburner is turned on, the vertical climb of j20 is accelerated crazily, just like a sharp sword piercing the sky!

after a few seconds.

Once again, I came to the j5000 at an altitude of 20 meters, and began to perform aerobatic performances in various attitudes in the air in the state of afterburner.

Roller Spiral Flight, Bell Maneuver, Falling Leaves, Cobra Maneuver, Super Cobra Maneuver...

As the j20 flew over the exhibition repeatedly, everyone was mesmerized and fascinated.

However, this situation did not last long, and was broken by a sudden exclamation from the crowd.

"Damn it! The afterburner has been turned on for a few minutes. Doesn't it mean that the afterburner can't be turned on for more than 2 minutes? If it exceeds 5 minutes, it will cause irreversible damage to the engine. Why is the j20 still on!"

As the words spread among the crowd, everyone woke up like a dream.

"That's right, seven or eight minutes have passed! The engine must have started to melt!"

"I'm going! I'm afraid the pilot is flying high and forgot about this?"

"Laughing, which one who can fly the J20 is not an ace pilot, will others forget this kind of life-threatening matter?"

"Hiss... If you put it this way, there is only one possibility, and that is the latest ws15 engine, which can withstand a longer period of afterburner!"

"Good guy, the super steel material is so good? It can even extend the afterburner state!"

Just when military fans were talking about the afterburner status of J20.

Fu Linnan, the chief engineer at the exhibition, said with a smile: "We said before that this latest ws15 uses a brand new design and materials, so its afterburner state will last for a long time."

"As for the specific length, I can only say that if it is under the condition of unlimited fuel, its afterburner state time can last up to 35 minutes."

35 minutes!

Hearing this unbelievable number, everyone present, including purchasing groups from various countries around the world, were all shocked.

They had thought that the afterburner state of ws15 might last for a long time, but they didn't expect it to be so outrageous!

You must know that all the fifth-generation fighters in the world now, even under certain circumstances, the duration of their afterburner will be very short, only five or six minutes at most, or less.

There are two main reasons here.

One is not enough fuel.

Second, the material is not allowed.

In fact, to put it bluntly, afterburner is to add fuel to the afterburner chamber filled with high-temperature gas, and use secondary combustion to obtain additional thrust for the engine.

However, since the exhaust gas after combustion is used at this time, its oxygen content has been reduced, so the combustion efficiency is not high.

This also means that afterburner is a means to increase thrust in a short period of time at the cost of sacrificing a large amount of fuel and reducing fuel efficiency.

Therefore, it is no exaggeration to say that afterburner is burning aviation fuel and money.

Every minute of burning, that is nearly a ton of aviation fuel, which is also tens of thousands of soft sister coins.

Secondly, when the afterburner is turned on, the temperature of the combustion chamber and other parts of the engine will continue to rise, reaching an astonishing several thousand degrees.

In this case, even if the engine parts have high fire resistance, they cannot withstand the high temperature of thousands of degrees for a long time, so they will melt.

Therefore, in the eyes of everyone, it is simply unbelievable that the latest ws20 engine on the j15 can have an afterburner time of 35 minutes.

"Of course, what I'm talking about is only under the ideal situation of unlimited oil."

Seeing everyone's shocked faces, Chief Engineer Fu Linnan continued to laugh and said, "Under normal circumstances, the afterburn time of our j20 is conservatively estimated at about 10 minutes."

The voice fell.

In the sky above the exhibition, J20 finally slowed down and began to turn off the afterburner.

Immediately afterwards, j20 completed the last low-altitude dive flight, and immediately disappeared from everyone's eyes.

After watching j20 leave, everyone slowly came to their senses.

Seeing this, Fang Xu, the engineer next to him, quickly stood up and said, "Everyone, this is the true strength of the j15 that has been replaced with two ws20s, so now let us thank Fu Linnan, the chief engineer of the ws project, and Lin Yu academician."

"It is their hard work that can make ws15 mass-produced. Please give them the warmest applause!"

After the engineer Fang Xu finished speaking, the scene immediately burst into applause.

Everyone knows what the breakthrough of ws15 represents.

And all of this is because of Lin Yu and Fu Linnan, chief engineer.

Seeing this scene, Lin Yu, as a tool man, naturally smiled and applauded, and then stepped off the stage with Chief Engineer Fu Linnan.

After the two left, the applause continued for a long time.

The first outdoor exhibition is over.

However, the sensation caused by ws15 has only just begun.

It's just that Lin Yu is not in the mood to pay attention to all this now.

Because after finishing the first ws15 exhibition, he was led by Zhao Yu again to the second outdoor exhibition.

This exhibition is a panoramic combat of ground armored forces.

Among them, there are more than 4 kinds of ground equipment such as VT5 main battle tank and VT30 light main battle tank. In the panoramic site, real-scene demonstrations such as climbing longitudinal slopes, crossing ditches, wading pools, and snake-like maneuvers are carried out.

These simulated training scenes are very realistic and look shocking.

However, after a long time, Lin Yu became a little bored.

But there was no way, he couldn't leave even if he wanted to.

Because these ground armor units also use super steel materials.

Moreover, what makes Lin Yu even more desperate is that all the themed exhibitions in the four aspects of "sea", "land", "air" and "sky" in the entire air show have all been applied to super steel materials.

That is to say, in the next 5 days of the air show, Lin Yu will probably act as a ruthless tool man.

Time passed slowly.

Just as Lin Yusheng was watching one theme exhibition after another without love.

The videos and information about ws15, super steel, and j20 flying stunt performances on the Internet spread wildly.

You know, as an airshow held every two years, its popularity is not low.

Not to mention that the air show is also related to Lin Yu, so it naturally attracted the attention of countless people around the world.

All of a sudden, whether domestic or foreign, major news media and short videos began to be filled with various reports.

Especially the terrifying data of j20, and the video of it breaking through the speed of sound and piercing the sky with sonic boom clouds deeply shocked everyone who watched the video.

"Damn, I'm not educated, I can only say one thing about my motherland!!"

"It's so hot, I can't wait to hear J20's dragon chant in person."

"From now on, who has the right to dare to say that our fighter jet engines are not good!?"

"My lords, listen to the dragon's singing that shakes the heavens!"

"My Huaxia has finally returned to the top of the world in the field of aviation development!"

"Grass! The cultural person upstairs! What I said made my whole body ignite!"

"Let's not talk about it, I'm already going to buy tickets for the professional day, isn't it only 2000 yuan, it's really worth it!"

"Count me in!"

All kinds of proud and proud comments from Chinese people filled the comment area.

The names of Lin Yu and Fu Linnan, chief engineer, also spread across the country in an instant through the Internet, and were known by countless people.

However, compared to the pride and pride of Chinese people, netizens from other countries around the world are amazed by this information.

Not only that, but as the air show incident continued to ferment, many Chinese people flocked to the air show.

This also led to the originally harmonious and orderly professional Japanese air show suddenly becoming lively.

For this scene, Lin Yu naturally didn't care at the beginning.

It was only when he got to the back that he started to have a headache.

Because almost all of the people who poured in came running for him.

Moreover, what makes Lin Yu feel helpless most is that these people not only like to ask him various questions, but also like to take photos with him.

Lin Yu originally planned to refuse, but he really couldn't stand the enthusiasm of the people and the above meaning.

After all, Lin Yu attended the air show this time as a scientific researcher.

And countless researchers are very envious of Lin Yu's treatment.

You must know that no scientific researcher can refuse the opportunity to speak freely with the Chinese people and introduce the things they have developed.

Because, in the eyes of researchers, such treatment not only symbolizes glory, but also the pride and pride of the motherland being strong because of itself.

These things are priceless.
