Behind, Li Zhen and others also saw this scene through a telescope.
Liu Jinghong couldn't help but go crazy: "How is this possible? He's raising his head now? The car hasn't even picked up speed yet, and it's only been running for one kilometer. How come it's raising its head so quickly?"
Li Zhen sweated in his fists and thought to himself, this time, it seems there is a way.
Xu Xiufeng slowly pushed the operating lever upwards, and the biplane's double-layered wings were at a horizontal and parallel angle and slowly tilted up at the same time.
In breaking wind mode, transition into ascending mode.
The air fluid, invisible to the naked eye, rushes through the two layers of wings and is then discharged through the back of the wings. Produces double the winning lift.
Just after Xu Xiufeng pushed the control stick to the take-off angle, Xu Xiufeng suddenly felt a powerful energy, making him feel weightless.
The plane began to raise its head fiercely, its rear wheels rubbed against the ground and continued to move forward at a speed of forty yards.
Forward power is converted into lift, which is knowledge in fluid mechanics. The people at the Aviation Institute have memorized these laws countless times, but now, they have truly experienced what this feels like.
It was a beauty that cannot be described in words.
Soon, the two rear wheels also lifted up and lifted off the ground.
At that moment, the steam car suddenly lost power, paused, and then drove forward at a crazy speed again. The speed of the steam car actually began to increase steadily. Forty-five miles, fifty miles!
Breaking the fifty kilometers per hour mark.
Just when the driver was confused, he suddenly heard a scream coming from behind: "Ah! So happy!"
"Success!"
Turning his head, his eyes widened in confusion.
But behind the car, there was a double-decker plane connected with a rope.
At this time, it flew into the blue sky like a big kite. Towed by the steam car, it moved forward in the air against the wind.
The height is about ten meters.
Sixty miles!
The driver suddenly discovered that the steam car burst into violent acceleration. In an instant, I realized that this was because the friction between the aircraft and the ground was separated from the hundreds of kilograms of strong friction, and the friction between the aircraft and the earth was converted into the friction between the aircraft and the air.
In comparison, the friction of air is much less than that of earth.
After silently recording this point in his mind, the driver drove forward even more excitedly.
There were loud discussions on both sides of the runway.
"Then why did it fly?"
"What is the principle of this?"
"I know that this is a research result of the Kyushu Academy of Sciences a long time ago. This is called fluid mechanics."
"No, it's aerodynamics."
"It really took off."
"These double wings are really strong, and I can fly so easily."
"But... what happens next? Will I be dragged down by a steam train forever?"
“…”
Behind, everyone in the aviation academy jumped up with cheers.
"Success!"
"The double-decker aircraft took off successfully."
"The test is feasible. Quickly, record the data, how many kilometers and at what speed it took off. Be sure to record it in detail."
"This is a well-deserved event in the history of world aviation and should be written about in a big way."
"In the end it was the bidecker that won."
“…”
Li Zhen was also so excited that he couldn't calm down. Unexpectedly, no one was optimistic about it at the beginning. The big, dumb, heavy bi-decker achieved ultimate fruition.
Looking around, he saw Liu Jinghong looking ahead with a complex expression and saying nothing.
Li Zhen patted him on the shoulder: "Don't be discouraged."
Liu Jinghong shook his head: "Master Li, I am not discouraged. I just firmly believe that the king's way is a single-decker wing aircraft after all."
Li Zhen smiled and said: "Maybe the future will be what you said. But at present, the problem of power cannot be solved. This... is difficult."
Liu Jinghong was silent for a long time: "I will not give up. Master Li, I will definitely develop a single-decker wing aircraft that will shock the world. Single-decker wing aircraft should be the true overlord of the blue sky."
"I'm optimistic about you."
“…”
The two were talking.
But a few kilometers away, Xu Xiufeng's expression in the sky changed wildly. In the air, he suddenly felt waves of bumps.
'Gah' sound.
Xu Xiufeng's face turned pale, and he turned his head, only to see that the lower wing on the left suddenly broke. It wasn't that the wings were broken, but that the wire holding the wings was broken.
"No!"
Xu Xiufeng screamed and quickly pushed the operating lever to control the wings to fall.
Everyone only calculated how many kilograms of force the wings needed to bear, but they all ignored the pulling, pulling, wires that controlled the movement of the wings, and the transmission system, which actually had to bear the same weight.
It's okay if he doesn't move the operating lever, but if he moves the operating lever. The steel wires and transmission system, which were originally in a tight state, were affected by external forces and were all out of balance.
'Karma'
The wire on the upper right wing was broken.
"ah… "
Xu Xiufeng could no longer control the operating lever. Because at this time the plane had begun to shake violently. Like a plastic bag in a strong wind, swaying uncontrollably.
Now and then left, now right, doing vigorous movements.
The driver of the steam car discovered this problem. Hearing the screams in the air, he turned around and saw that Xu Xiufeng had been thrown out of the plane. Detached from the cockpit and hung outside. If the safety rope hadn't connected him, he would have been thrown away long ago. Even so, he was thrown out of the plane.
Subconsciously, the driver of the steam car stepped on the brakes.
The moment the brakes were applied, the driver realized something was wrong.
wrong!
The aircraft is towed by a rope, and the rope is in a taut state. Only by slowly decelerating yourself in a tight state can the plane land safely.
But suddenly the brakes were applied hard, and the traction rope slackened instantly.
The plane... actually passed over the steam train pulling it, and fell forward driven by inertia.
"No!"
Behind them, Li Zhen and the others yelled crazily, then boarded the steam car with an angry look and headed towards that place.
On both sides of the road, everyone's eyes widened with horror.
I just saw that the plane passed over the steam car, and then fell forward.
"ah!"
The shrill screams resounded throughout the sky.
Xu Xiufeng clung to the edge of the cockpit door and closed his eyes, not daring to look at the land that was getting closer and closer.
After closing his eyes, he suddenly felt that his heart was extremely peaceful and quiet, without the despair he imagined...
Perhaps, just like what he said on the day when he succeeded in paragliding: The blue sky is my destination.
'bang'
There was an explosion.
The plane fell to the ground and dust filled the sky.
When the dust cleared, the ground was covered with debris.
Wooden frames, steel pipes, steel wires, and wooden blocks were scattered everywhere in a mess.
The farthest part flew dozens of meters away.
Xu Xiufeng lay there in a bloody state, with a large piece of wood printed on his head.
The dust dispersed, and the entire Gale Tower was filled with countless onlookers in silence.
When Li Zhen and others felt it, Liu Jinghong collapsed and cried: "Old Xu!"
Everyone recovered from the shock and rushed over in a swarm: "Help!"
"Hurry and save people!"
“…”
Li Zhen took a deep breath, his eyes turning red. Looking at the bloody old body, I felt extremely uncomfortable.
In the chaos, everyone at Kyushu Academy of Sciences was confused.
I don’t know how I came back from Gale Tower, but the atmosphere was extremely depressed.
Everyone couldn't help but sigh, and couldn't help but sigh...
This seventy-eight-year-old man who became a monk on his way out, was once a senior lecturer at Imperial College, and is now the deputy director of the Aerospace Power Research Institute of the Kyushu Academy of Sciences. In the end, he left his fate to the sky.
The test flight test was successful.
So God accepted him.
