I tinkered with cars and built a super military industry

As the fighter jet spit out a stream of black smoke from behind.

"grumble!"

A sharp phoenix cry sounded.

The rotating detonation engine started quickly.

After the fighter jet passed the self-inspection, it moved its front and rear wings.

Then slowly move towards the runway until takeoff.

This time the fighter plane is equipped with a live camera.

Moreover, there are many fighter planes tracking and filming along the routes and over uninhabited areas.

The black fighter jet accelerated instantly after flying into the air.

Mach one, Mach two, Mach three, Mach four, Mach five...

At this time, the shooting fighter planes along the route reported to the tower center.

"Tower, tower, I'm number one, I'm number one."

"The black fighter plane just flew past me, very fast."

"The speed checker showed that the speed of the black fighter during the test flight was Mach 5."

After receiving the information from Fighter No. 1, Su Zheng and others immediately called up the shooting footage of Fighter No. 1.

I saw the No. 1 fighter plane flying at a constant speed, and suddenly a black fighter plane passed by.

When the camera captured it again, only the tail nozzle of the black fighter jet during the test flight could be faintly seen.

So fast!

Before Su Zheng and others could react, they received a call from the second fighter plane.

"Tower, tower, I'm the No. 2 fighter. I'm the No. 2 fighter."

"If you receive it, please reply. If you receive it, please reply."

"Tower received."

"The black fighter jet just passed by my cruising position, it was too fast."

"The speed check instrument shows that the speed of the black fighter plane is over Mach 10."

The staff quickly pulled up the actual picture of the second fighter plane.

From the footage taken by Fighter No. 2, Su Zheng only saw a black stream of light passing by.

In the black stream of light, you can see a little bit of blue-red tail flame.

At Mach 10, it can reach 3,440 meters per second.

Such a fast fighter speed is simply unheard of.

Su Zheng and others were extremely surprised when they saw a black line on the screen.

Even slow motion cannot capture the full view of the fighter plane.

"Tower, tower, I am fighter number three, I am fighter number three."

"A UFO just flew by me."

"It can be seen from the speedometer that the speed of the UFO is above Mach 20."

Su Zheng heard the news from Fighter No. 3 and said excitedly:

"Hurry up and bring up the factual footage of Fighter No. 3."

The tower staff brought up the picture of Fighter No. 3.

Compared to the black line shot by the No. 2 fighter plane.

What the No. 3 fighter plane captured was a flashing black spot.

At Mach 20, it can fly 6,800 meters per second.

Blink out of sight.

"It's so fast, it's so fast!" the staff present commented.

"This is the first time in my life that I have seen a fighter plane flying so fast."

"This speed breaks my cognitive barrier to speed."

"Mach twenty turns out to be so fast!"

"It's hard to control such a fast fighter plane!"

"Besides, how could the fighter plane stop at such a fast speed?"

"You shouldn't think about how the fighter plane stopped."

"What we should consider now is how fighter jets can reach speeds above Mach 20."

"What is the engine of that black fighter plane?"

"I heard it looked like a rotary detonation engine."

"The detonation engine is also a fuel engine!"

"That's right! It's not an anti-gravity engine."

"I heard this fighter plane has twin engines."

"In addition to the rotary detonation engine, there is also an oblique detonation engine."

"Oblique detonation engine?"

"Never heard of it!"

"I told you to read more information. If you don't listen, you must be illiterate now!"

"The oblique detonation engine has actually always had this concept, but no successful engine has ever been built."

"In addition to pulse detonation engines and rotating detonation engines, they all have difficulty in controlling deflagration waves."

"The technology for oblique detonation engines will be more difficult."

"The oblique explosion engine also does not have turbofans, compressors and other components."

"Some are just two inclined planes squeezing the air."

"It's then mixed with fuel and injected into the combustion chamber."

"The advantage of the oblique detonation engine is that the faster the fighter plane, the greater the thrust of the engine."

"You can accelerate without limit!"

"But the oblique detonation engine has a disadvantage, which is that it cannot start at speeds below Mach 5."

"Theoretically, the rotary detonation engine of a fighter jet only provides acceleration from zero to Mach five."

"After exceeding Mach 5, the oblique detonation engine provides full acceleration."

"You are so powerful, I feel like you built this fighter jet, and you speak so eloquently."

"You can know all these theoretical knowledge by checking the information."

"But although the theory makes sense, in reality, no one can build such an engine."

"It's too difficult."

"It would be amazing if the black fighter plane tested was really equipped with this kind of engine."

"On aircraft engines, it will blow away the bald eagle nation by a few blocks."

And when Yunfan saw the black fighter jet flying, he couldn't help but swallowed.

The fighter plane on the drawing was really designed by Li Yifan.

Not only Yunfan thought that it was impossible to build a fighter jet, but Su Zheng also believed that it was impossible to build a fighter jet.

In the current aviation world, even if the blueprints were given to the Bald Eagle Nation, they would not be able to build a fighter jet in a short time.

After all, this fighter aircraft is a product of a transcending era.

"Dean Su, does this black fighter have a name?" Yun Fan asked.

"Not yet." Su Zheng said.

"Why don't we just call it the Black Snake Fighter!"

"The sound of black snake gives people goosebumps." Yunfan said.

"This has to be decided by a vote by the people of China, not by me." Su Zheng said.

"Yes, such a sharp weapon belongs to everyone in our country of China." Yun Fan said sarcastically.

Over the next week, the test pilots repeatedly flew the black fighter in various ways.

But none of them raised any issues that needed improvement.

For this reason, Su Zheng decided to mass-produce the new fighter jets with Li Yifan as the leader.

The sooner such a fighter plane is equipped, the better, so as to avoid long nights and dreams.

According to the previous method of manufacturing tanks, Li Yifan brought Yun Fan and others from the Aviation Department with him when manufacturing and assembling fighter planes.

Fill in the data while assembling.

If Yun Fan and others don't understand, Li Yifan will explain it to them individually.

If you don’t understand something after explaining it once, explain it twice. If you don’t understand it after explaining it twice, explain it three times.

Until they understand.

Li Yifan's unreserved explanation also won the admiration of Yun Fan and others.

Generally speaking, even if the developers are willing to talk about cutting-edge scientific research technologies like this, they will not talk about them all.

If a master teaches his disciples to starve to death, the chief developer will have some reservations.

On the other hand, Li Yifan not only had no reservations.

He will also explain it clearly and clearly to the questioner in a very detailed manner.

As long as someone asked, he would tell it, without reservation.

As a result, among this group of academicians of the Chinese Academy of Sciences, many are academicians in their forties or fifties.

But he was respectful to the eighteen-year-old Li Yifan.
