'Buzz'

In the blue sky, there is a touch of frightening.

The merchant in the wilderness in the distance suddenly looked up and looked at the eagle in the blue sky with dementia.

"This ......"

"Is it an airplane?"

"The Swordfish of the Kyushu Academy of Sciences has begun its test flight?"

“……”

In all directions, there were also people in Qingdao County who looked up and looked at the goshawks hurrying across the sky, with a look of anticipation on their faces.

The feeling of this eagle looking down on the earth is truly a supreme enjoyment. Everyone understands a little bit of the feeling of the eagle, the absolute overlord in the blue sky, and when it overlooks the earth, it will feel that all beings are like ants.

In the sky above Laoshan County, countless people raised their necks and shouted:

"The plane is coming!"

"Goodbye plane!"

“……”

Many people saw the Swordfish turn around and go in the direction of the sea, and ran after it frantically and excitedly.

————

On the plane, Fang Aerospace finally felt why he sensed something wrong.

He found that the problem was on top of the direction control.

Before, he always felt that after flying into the sky, the operation was a little awkward. But he couldn't say what was awkward, but he thought it was probably his first time trying this kind of aircraft, so he wasn't fully familiar with the control.

But now, he finally knew what was awkward.

Swordfish ...... Straight flight is not possible!

This is a somewhat frightening cognition, especially for a pilot like Fang Aerospace who is in the sky, this problem is fatal and unforgivable!

Because the perspective in the sky and on the earth are not the same, and the senses are also different.

On the ground, you can judge your direction and position based on various references to the ground and landmarks.

But in heaven. Sorry, no.

Looking from heaven to earth is another perspective, another kind of reference. The thing you see the most is actually the blue sky and white clouds.

What is under your feet tends to be overlooked.

And this is a great test of the pilot's sense of direction and eyesight.

But a test is a test.

One of the most critical factors involved is the aircraft itself.

If the plane is not able to fly in a straight line, the pilot will get lost in the air.

The airship is good to say, it can land straight up and down.

But an aircraft like the Swordfish, which requires runways to take off and land, is a fatal drawback.

If you get lost, you won't even find where to land. You can't tell the coordinates.

In this era before radar was born, pilots could only judge their orientation by their eyes and perception. But now, there is a problem with the operating system of the aircraft, and when the control stick is completely stationary, the aircraft is always moving in an arc to the left, rather than flying in a straight line at all.

Fang Hongtian calmed down in the air, carefully felt the orientation of the ground, and carefully adjusted the control stick to get a 'straight line balance' direction angle.

Suppose the plane is always cheaper to the left. Then Fang Hongtian controlled the plane to fly to the right. Use a hedge of one left and one right to achieve a straight line balance.

The level of precision required for this is extremely high.

And Fang Hongtian had no horizontal reference, no matter how hard he tried to adjust the balance, he never came up with a real angle.

As Fang Hongtian kept adjusting his direction, the plane began to sway from side to side.

The amplitude is very dramatic.

Because the Swordfish, which mainly uses its wings to control its direction, it should not perform directional maneuvers too frequently. Because an airplane is not a car, it is not a place to hit.

When driving, you turn the steering wheel to the left, and the car immediately turns left.

But when flying an airplane, it doesn't matter what kind of plane. Because its direction system basically uses the principle of air and fluid.

So there is a delay for a certain amount of time.

This delay is a bit higher on the Swordfish.

The buffer is about 0.8 seconds.

That is, when you have the lever in place, you are sure to fly to the right. Then it will be 0.8 seconds before the plane actually starts to fly to the left.

With a delay of 0.8 seconds, the plane has already flown a distance of almost twenty meters. The error is large.

And in the case of directional delay, there is the fatal disadvantage of not being able to fly in a straight line. Fang Aerospace was eager to control the plane, rather than letting the plane control himself, and he began to operate the steering system frequently.

These things didn't exist in previous airships, so he didn't have a lot of awareness of the problem of frequent turning.

When he goes to the left for a while, and then to the right.

When the operation is too frequent.

The plane began to shake violently.

Crazy and constantly swaying from side to side, Fang Hongtian became anxious in his heart, no matter how calm he was, he couldn't calm down at this time. Whoever flies the plane in the sky, encounters the plane and suddenly starts shaking, uncontrollable, and no one can calm down.

The more anxious he was, the more mistakes Fang Hongtian made.

Turning to the left, he was stunned for a moment and muttered, "No, no." ”

With a movement of his hand, he struck to the right again.

"It's a little much."

As he spoke, he hit the direction to the right and moved back a little bit.

The plane shook more and more violently, and if Fang Hongtian wasn't wearing a seat belt, he would have almost been thrown out.

Riding motorcycles and electric vehicles, you should have such an experience.

When you turn more frequently within a period of time. The front of the car will start to shake suddenly, and if the force is smaller, it will even be thrown off by the handlebar. Then the front of the car will increase in amplitude until it falls, or stops.

And now, Fang Hongtian is experiencing this phenomenon. This is a phenomenon of inertia.

In particular, he is still in heaven.

Rao has participated in many flights, and he can't be calm at this time.

On the runway of the airport, the crowd was in an uproar.

They all pointed to the sky and exclaimed: "Why is it like that......"

"What's going on? Why did it start shaking? ”

"Why is it so big? Walking the serpentine route? ”

"Is this a flying stunt?"

"No, I don't think the plane is out of his control."

"What's going on?"

“……”

In the pergola, all the VIPs also ran out, and they all looked at the phenomenon in the sky with clairvoyant mirrors.

Liu Jinghong's face turned pale, his whole body trembled, and he muttered, "How can this be? ”

"How so?"

"Why is this happening?"

“……”

Li Zhen also observed with a clairvoyant mirror, but his heart was already a lot calmer at this time.

It was only when he saw the plane in the sky turning just now that he suddenly remembered this truth, if the horsepower on the two sides is different, then it will cause it to be unable to fly in a straight line.

Li Zhendian didn't think about the specific consequences, but he knew that he had to leave the crowded place as soon as possible to go to the sea to be safe.

Now I see that the fuselage is shaking violently, and I understand why this is happening. Inertial imbalance due to orientation defects.
