Chapter 494: Landing Successfully, Encountering a "Dolphin Jump"

The backup power supply has been completely exhausted and the plane is now completely without power.

Jiang Chen glanced at the dashboard which had turned completely dark.

After the fighter plane flew about a hundred meters along the runway, it gently pulled up the nose of the plane to ensure that the rear landing gear of the plane landed first.

It is actually very risky for Jiang Chen to do this.

Because now the cockpit has been completely cut off from power.

He could only check the aircraft's status based on his intuition rather than through instruments, and he had no idea of ​​the aircraft's altitude or angle.

However, as an experienced pilot with more than ten years of experience, Jiang Chen's intuition is still relatively accurate.

as predicted.

Just after he pulled up the nose of the plane slightly.

Bang!

The rear landing gear of the plane hit the runway heavily.

The huge rebound force instantly acted on the fuselage of the aircraft, and immediately bounced the aircraft into the air again.

Then under the dual effects of inertia speed and lift.

This J-11B fighter jet actually started flying along the runway again.

Hey!
Dolphin jump?
Jiang Chen was shocked.

The worst case scenario, the most brutal killing move finally appeared at the last moment.

The so-called "dolphin jump" refers to the abnormal pitch oscillation phenomenon that occurs when an aircraft is in flight, usually during the landing phase.

If an airplane encounters a "dolphin jump", the fuselage will continue to shake and even sway up and down.

Like a frightened wild horse.

Even though the reins were around his head, the rider had already jumped onto the horse's back.

But it continued to roar and jump, as if it would not stop until it threw the rider off its back.

Jiang Chen is now a rider riding on horseback.

And this J-11B, which is on the verge of losing control, is the wild horse that has broken free from its reins.

If Jiang Chen has no other choice.

The wild horse would probably throw him off its back immediately.

By then, it will probably be completely forgotten.

So when Jiang Chen judged that the plane encountered a "dolphin jump", he responded immediately.

He immediately pulled the control stick back and upward, pulling the nose of the plane up again.

Lower the flaps and spoilers simultaneously.

Reduce the aircraft's lift.

really.

After he responded, the plane flew about twenty or thirty meters along the runway, and the rear landing gear hit the runway again.

this time.

The plane did not bounce up again like before, but after a bumpy ride it began to slide along the runway.

next second.

The front landing gear also hit the runway heavily.

Jiang Chen's heart finally settled down again.

There are many reasons for an aircraft's "dolphin jump", such as the pilot's operational error, failing to pull the aircraft into a two-point landing posture, but instead landing in a three-point posture (the front and rear landing gear hit the runway at the same time).

This causes the shock absorber of the aircraft landing gear to produce a large rebound force, which increases the aircraft's pitch angle and lift, causing the aircraft to gain lift and bounce back.

Or although the aircraft's landing posture is a two-point posture, the height from the ground is high, the main wheel reaction force is large, forming a nose-down moment, the pilot fails to hold the stick, and the landing gear hits the ground hard, causing the aircraft to jump.

Or the aircraft encounters severe weather such as strong air currents or crosswinds.

Or maybe there is equipment malfunction on the aircraft.
There are many reasons for a 'dolphin jump', and it can easily lead to extremely serious consequences.

The reason why this J-11b encountered a "dolphin jump" is simple. That is, the aircraft's engine malfunctioned and stopped, and the backup power supply was exhausted. After gliding for hundreds of kilometers, the pilot was unable to slow down during the landing phase.

When the plane hit the runway heavily, the shock absorbers of the landing gear were triggered.

So the plane was bounced back into the air.

But the 'dolphin jump' was just a small episode.

Although the plane has now landed steadily on the runway and started running wildly along the runway, it does not mean that Jiang Chen is safe.

Just after the plane landed for the second time.

Jiang Chen quickly turned on the taxi lights, landing lights and parachute one after another.

But what surprised Jiang Chen was that when he pressed the parachute button, the plane did not respond at all.

Failed to release the umbrella?

These four words immediately appeared in Jiang Chen's mind.

To know.

The landing speed of a fighter jet can easily exceed 200 kilometers per hour.

Although this J-11B fighter jet has glided for hundreds of kilometers, its current speed is maintained at kilometers per hour.

A large amount of slid distance was wasted because of the dolphin jump.

This results in the runway being not long enough.

In fact, the best way to solve the "dolphin jump" is to take off again.

Most pilots will choose to take a go-around after encountering a "dolphin jump".

But Jiang Chen can't.

It’s not that he likes to be cool or special.

Rather, the engine of this J-11B fighter jet is simply unable to provide thrust.

A plane without sufficient power.

What the hell is flying?

So after discovering that the parachute could not be opened, Jiang Chen wanted to punch the cockpit instrument panel.

Fuck you.

This is really a case of "misfortunes never coming singly".

The plane landed successfully.

The parachute wouldn't deploy.

The deceleration of a passenger plane after landing mainly relies on reverse thrust, while the deceleration of a fighter jet after landing mainly relies on a parachute.

Now the J-11b's parachute cannot be opened, which is as dangerous as the failure of the reverse thrust device of an airliner.

“Calm down~~~Calm down~~~Calm down~~~”

Jiang Chen took two deep breaths.

Force yourself to calm down.

"How did I solve the reverse thrust device failure last time? That's right, I slowed down slowly along the length of the airport."

"But I'm already halfway across the runway and the plane can't slow down."

"How to do how to do?"

far away.

Weifang station control tower.

The controller has also discovered the anomaly.

So he hurriedly reminded loudly, "Qianzhilu, release the parachute, release the parachute, your parachute is not open, your parachute is not open."

Jiang Chen shook his head in annoyance.

grass.

I don't know whether the parachute was opened?

Want you to remind me?

Jiang Chen gritted his teeth.

Hold the control stick with one hand to ensure that the aircraft's taxiing posture remains stable.

Then slam on the deceleration pedal.

Only emergency brake can be used.

Yes.

In emergency situations such as when a fighter jet encounters a parachute that fails to open, the pilot can activate the emergency brake by operating a specific handle or pedal.

Once the emergency brake is activated, the device will provide maximum braking force to ensure that the aircraft can be stopped in the shortest possible time.

But emergency braking also has a big disadvantage.

That could easily cause the plane to completely lose control and run off the runway.

Although the design of the fighter aircraft emergency braking device is very complex, the design concept is similar to the braking principle.

When braking a bicycle, you only need to squeeze the brake handle tightly, and the brake pad and the steel rim of the wheel will be tightly pressed together through the brake line to achieve the braking effect.

The fighter's emergency brakes reduce the wheel rotation speed through the friction between the brake pads and the brake discs, thereby quickly decelerating the aircraft.
