'buzz buzz'
In the blue sky, a flash of lightning flashed across.
The businessman in the wilderness in the distance suddenly raised his head and stared blankly at the eagle in the blue sky.
"this… "
"Is it a plane?"
"The Kyushu Academy of Sciences' Swordfish has begun its test flight?"
“…”
In all directions, some people in Qingdao County raised their heads and looked at the eagles flying across the sky with a look of anticipation on their faces.
The feeling of this eagle overlooking the earth is really a supreme enjoyment. Everyone now understands the feeling of the eagle. It is the absolute overlord in the blue sky. When it overlooks the earth, it will feel that all living beings are like ants.
In the sky above Laoshan County, countless people raised their necks and shouted:
"The plane is coming!"
"See you on the plane!"
“…”
Many people saw the Swordfish turning in a circle and heading towards the sea, and they followed it wildly and excitedly.
——
On the plane, Fang Aerospace finally felt why he noticed something was wrong.
He discovered that the problem lay in directional control.
He always felt that after flying into the sky, the operation was a bit awkward. But he couldn't explain why it was awkward. He just thought it was probably his first time trying this kind of aircraft, so he wasn't completely familiar with the control yet.
But now, he finally understood what was awkward.
The Swordfish...cannot fly in a straight line!
This is a somewhat horrifying realization, especially for a pilot like Fang Aerospace who is in the sky. This problem is so fatal that it is simply unforgivable!
Because the perspective is different in heaven and on earth, and the senses are also different.
On the ground, you can judge your direction and position based on various reference objects on the ground and landmarks.
But in heaven. Sorry, no.
Looking from the sky to the earth is another perspective, another reference. The thing you see most is actually the blue sky and white clouds.
What's underneath your feet is often overlooked.
And this is a great test for the pilot's sense of direction and vision.
But a test is a test.
The most critical factor involved is the aircraft itself.
If the plane cannot fly in a straight line, the pilot will end up getting lost in the air.
Fortunately, the airship can land straight up and down.
But an aircraft like the Swordfish that requires runway takeoff and landing is a fatal drawback.
If you get lost, you won't even know where to land. You can't tell the coordinates.
In this era before radar was born, pilots could only rely on their eyes and perception to determine direction. But now, there is a problem with the aircraft's operating system. When the control stick is completely stationary, the aircraft always draws an arc to the left, instead of flying in a straight line at all.
Fang Hongtian calmed down in the air, carefully felt the position of the ground, and carefully adjusted the control rod to arrive at a 'straight-line balance' direction angle.
If this plane is always heading to the left, it will be cheaper. Then Fang Hongtian controlled the plane to fly to the right. Use one left and one right offset to achieve a straight line balance.
The precision required is extremely high.
Fang Hongtian had no horizontal reference. No matter how hard he tried to adjust the balance, he could never get a true angle.
As Fang Hongtian continued to adjust its direction, the plane began to shake from side to side.
The magnitude is very dramatic.
Because the Swordfish mainly uses its wings to control direction, it cannot perform directional operations too frequently. Because an airplane is not a car, it doesn't mean it can hit anywhere.
When driving, if you turn the steering wheel to the left, the car will immediately turn to the left.
But when flying an airplane, no matter what kind of airplane. Because its direction system basically uses the principle of air fluid.
So there is a certain amount of time delay.
The delay of the Swordfish is higher.
The buffering time is about 0.8 seconds.
In other words, when you have the control stick in place, you must fly to the right. Then it will be 0.8 seconds before the plane will actually start flying to the left.
With a delay of 0.8 seconds, the plane had already flown nearly twenty meters. The error is huge.
On top of the directional delay, there is the fatal drawback of being unable to fly in a straight line. Fang Aerospace was eager to control the aircraft instead of letting the aircraft control himself. He began to operate the steering system frequently.
These things did not exist in previous airships, so he was not very aware of the problem of frequent turns.
When he goes left now, right now.
That moment when the operation is too frequent.
The plane began to shake violently.
Fang Hongtian became anxious as he kept swaying wildly from side to side. No matter how calm he was, he couldn't calm down at this moment. Whoever is flying a plane in the sky would be unable to calm down if the plane suddenly starts to shake out of control.
The more anxious he was, the more mistakes Fang Hongtian made.
He turned to the left, was stunned for a while, and muttered: "No, no."
As soon as his hand moved, he hit it to the right again.
"It's a bit much."
With that said, he hit the right direction and moved back a little.
The plane shook more and more violently. If Fang Hongtian hadn't been wearing a seat belt, he would have been almost thrown out.
You should have this experience when riding motorcycles and electric vehicles.
When you turn more frequently within a period of time. The front of the car will suddenly start to swing around, and if the force is smaller, it may even be thrown away by the handlebars. Then the front of the car will become larger and larger until it falls or stops.
Now, Fang Hongtian is experiencing this phenomenon. This is a phenomenon of inertia.
Especially since He is still in heaven.
Even though he had participated in many flights, he couldn't calm down at this time.
On the airport runway, people were in an uproar.
They all pointed to the sky and exclaimed: "Why did that happen..."
"What's going on? Why is it starting to shake?"
"Why is the amplitude so big? Take the serpentine route?"
"Is this a stunt?"
"That's not right. I feel like the plane is out of his control."
"How is this going?"
“…”
In the pergola, all the distinguished guests also ran out, holding telescopes and looking anxiously at the phenomena in the sky.
Liu Jinghong's face turned pale, his whole body trembled, and he murmured: "How could this happen?"
"Why is it happening like that?"
"Why does this happen?"
“…”
Li Zhen also observed with a telescope, but now he felt much calmer.
He suddenly remembered this when he saw the plane turning in the sky just now. If the horsepower on both sides is different, it will make it impossible to fly in a straight line.
Li Zhen didn't think about the specific consequences at the time of the lightning fire, but he knew that he had to leave the densely populated place as soon as possible and go to the sea to be safe.
Now I saw that the fuselage was shaking violently, and I understood why this was happening. Inertial imbalance caused by directional defects.
