Chapter 527 Entering a Death Spiral

Chapter 527 Entering a Death Spiral
Whoosh~~~
This K-8V stabilizer is like a kite with its string cut.

Under the influence of the earth's gravity, it falls uncontrollably from a height of ten thousand meters.

Even if it's a big lump of iron.

It is also easy to roll or lose direction if falling from such a high altitude.

Rather than straight up and down.

Because it will be affected by various air currents.

This is especially true for airplanes.

The reason why an airplane can take off and soar at an altitude of ten thousand meters is that the engine provides sufficient power, which is the main reason, but a reasonable aerodynamic layout is also very important.

If a reasonable aerodynamic layout is not designed, no matter how powerful the engine is, the aircraft will either disintegrate in the air or crash before flying very far.

This is why when the K-8V variable-stabilization aircraft wants to test high angles of attack and spins, it must first complete a high angle of attack of 98 degrees.

Because if there is not such a large angle of attack.

It is not easy for this K-8V stabilized aircraft to go into a tailspin.

In other words.

The tailspin of this K-8V stabilizer was artificially created.

Some time ago, Jiang Chen piloted a J-11B with both engines shut down and glided for hundreds of kilometers before returning to the airport successfully.

If there is no near-perfect aerodynamic layout design.

The ten-ton lump of iron probably plunged into the sea the next second after its engine stopped in the air.

The aerodynamic layout design of the K-8V variable stabilizer is also perfect.

If the engine stops in mid-air in a level flight attitude, the aircraft is estimated to be able to glide for at least dozens of kilometers.

However, at this time, the nose of the K-8V stabilizer was facing upwards.

The fuselage has an angle of attack of 98 degrees with the ground.

So the next second the engine stops.

The plane fell uncontrollably.

At the same time, it is affected by side winds and other factors.

The plane was originally facing up with its nose and its fuselage facing down.

But after a while, the plane began to flip in the air.

Jiang Chen just felt dazzled.

The whole person feels like sitting on a high-speed electric swivel chair, spinning non-stop.

However, the rotation speed is much lower than that of a high-speed electric swivel chair.

So his brain remained clear and was not affected in the slightest.

"Warning, stall warning~Warning, stall warning~Warning, stall warning~"

In the cockpit.

A red warning light had already lit up on the dashboard.

The stall warning sound also kept echoing in the cockpit, incessantly.

It went into a tailspin.

Jiang Chen immediately glanced at the aircraft altimeter.

In just over ten seconds, the aircraft's altitude had dropped from more than 10,000 meters to 8,000 meters.

Because the aircraft stalled and entered a tailspin.

So all the data on the dashboard in the cockpit have started to explode.

Death spiral.

Sure enough.

Whenever an airplane goes into a tailspin, whether intentionally or unintentionally, it is like stepping into the gates of hell.

Because a tailspin not only causes the engine to stall, it also completely destroys the flight attitude.

It is extremely difficult to change it.

This is more than just restarting the engine.

It also requires a near-perfect control of the aircraft's flight posture at the time.

In other words.

If the opportunity is not seized, it will be extremely difficult to restart the aircraft even if there is no fault in the aircraft engine.

And how to seize this opportunity?

It must be restarted immediately the moment the aircraft is flying level.

Because the plane entered a tailspin, it was like an invincible Hot Wheels falling from the sky.

That is, the aircraft is in a state of continuous rolling.

In order to find a level flight posture while constantly rolling, the aircraft engine must be restarted.

Even for a person with rich flying experience and superb driving skills, it would be extremely difficult to achieve this.

This is why the tailspin is also called the death spiral.

So when the plane entered a tailspin, although Jiang Chen was not greatly affected, his breathing began to become rapid.

His expression was no longer as calm as before.

His face was tense, his eyes were bulging, and veins even popped out on his forehead.

This has nothing to do with his physical fitness.

It is caused by being too nervous.

“Hoo~~Hoo~Hoo~”

He was breathing heavily, staring at the altimeter without blinking.

Because according to the test requirements.

After the plane reaches an altitude of 5000 meters, he can make a correction and restart the engine.

soon.

The plane dropped several thousand meters.

Almost in the blink of an eye.

The altimeter needle pointed to 5000 meters.

Near the surface of the Earth, the free fall of all objects under the influence of gravity is about 9.8 meters per second.

This acceleration refers to the rate of change of the object's velocity under the action of gravity, that is, the object's velocity will increase by 9.8 meters per second every second.

Put it simply.

That is, when an object is in free fall, the height required for one minute is about 18000 meters.

It can drop 18,000 meters in one minute.

So it’s only 5000 meters in altitude.

It doesn't even take 30 seconds.

So when the altimeter needle points to 5000 meters.

Jiang Chen immediately reached out and restarted the plane's engine.

But no matter what he did, the plane's engine remained indifferent.

Hey!
Jiang Chen felt that his flight suit was almost soaked with sweat.

I have been in the army for almost a year.

We have also had several fights with the Americans and Koreans.

But this was the only time he felt his whole body tense up and his heart in his throat.

After another failed restart.

Instead of recovering, the plane went into a negative spin.

"Negative spin, operation failure."

In the cockpit.

The reminder sounded again.

Jiang Chen wanted to punch the dashboard.

Oh shit.

Why is it so difficult?
But the more nervous he got, the harder it was to do.

The plane was originally flipping in the air like a Hot Wheels, but now it simply turned its fuselage downwards and kept spinning in circles in the air.

Negative tailspin.

It's much harder than a death spiral.

back row.

Captain Qin, who had been calm and composed at first, became a little nervous when he discovered that the plane was going into a negative spin.

He heard Jiang Chen's breathing getting louder and louder in the headphones.

I couldn't help but remind him, "Calm down. The more panicked you are at this moment, the more likely something will happen."

"Hoo~ho~ho~"

Jiang Chen let out a long breath of foul air.

Then I kept reminding myself, "Calm down, calm down."

"But I can't fucking calm down."

"You can't not calm down. You have to calm down."

He suddenly closed his eyes slightly.
