Rising: Ten Thousand Years Chapter 323: : Double-wing test flight

Everyone was staring at the runway ahead. Especially Li Zhen clenched his fists unconsciously.

When running about a kilometer, one of the auxiliary steam cars broke the rope.

After the inertia is up, a steam car exerts force to drag it to run, the speed will be faster, and the force will be more concentrated.

Above the plane, Liu Jinghong nervously grasped the steering lever controlling the plane's wings, staring at the front intently.

"Take off."

"Why don't you take off yet?"

“…”

The speed has exceeded forty.

Half the distance, Liu Jinghong knew that he couldn't go on like this. The limit speed of the steam car is only about sixty or seventy, dragging myself to forty, I am afraid it is already the limit of the limit.

Gritting his teeth, Liu Jinghong pushed the lever up.

At the same time, the wings of the plane were connected by transmission rods and turned up a little.

With such a pry, the flowing air immediately began to turn into lift, providing upward power to the aircraft.

But with such a prying, the steam car in front suddenly stopped.

The student of the aviation academy who was driving saw the speed of the car drop so abruptly. This feeling is the feeling of huge wind resistance coming from behind.

Looking back inadvertently, the students of the aviation academy found that the front wheels of the plane behind them were raised a little, a little floating and a little frivolous.

Are you going to succeed?

Everyone held their breath.

Students from the Academy of Aviation even drove the horsepower to the maximum, and kept adding fire to the steam car. Constantly increase the output of the air valve. But the steam car has reached its limit, and the fastest is only so fast.

Liu Jinghong was sitting on the plane, his eyes fixed on the landing wheels below.

"Fly."

"Fly up."

"Fly up, please!"

Sitting in the plane, he was constantly ups and downs. I can clearly feel that the plane keeps raising its head, and then it keeps bumping and falling, keeps raising its head, and keeps falling again.

No, it's still not fast enough. The power is still not strong enough.

"Forty-five kilometers!"

In the steam car ahead, the driver suddenly scratched his neck and shouted.

When Liu Jinghong heard the words, a look of defeat immediately flashed in his eyes.

If there is still no sign of takeoff at a ground speed of 45 mph, then the road ahead will actually be full of ups and downs.

The distance of five kilometers will be reached soon. Liu Jinghong's monoplane was maxed out, but the front wheel was raised about ten centimeters. Didn't get off the ground at all.

After turning back, Liu Jinghong couldn't help feeling dejected and regretful: "It's just a little bit. If the speed reaches 60 kilometers, I'm sure it will be able to take off."

Li Zhen smiled and shook his head: "Sixty? No, I think it needs at least a hundred kilometers before it can fly safely, reliably and stably."

Liu Jinghong frowned: "Why?"

Li Zhen said: "Take off is just the first step. The most important thing is to move stably in the air. If the speed is lower than 100, it will be very dangerous. I worry that it may crash at any time."

Liu Jinghong sighed, that's the reason. How could he not understand.

But can the radial engine still under development be able to do this?

Can a radial engine provide a thrust of more than 100 kilometers per hour for an aircraft of several hundred kilograms?

It's hard.

If the conversion is carried out in this way, the radial engine must provide more than one ton of thrust.

With such a terrifying thrust, even Li Zhen has no confidence. Achieving it within ten years is a high-spirited achievement.

Li Zhen sat on the lawn and rested for a while, and said: "Now we can only see how the wings are."

As soon as we spoke, the biplane was ready.

Still the same pattern. Two steam cars came to pull the plant, and a rope broke halfway.

Like Liu Jinghong, Xu Xiufeng also wanted to conduct the experiment himself this time.

Li Zhen frowned and said: "Deputy President Xu, you are getting older. It is different from Jinghong. Leave the test to someone else. You saw it just now, bumps are indispensable. And this still has a certain risk factor .”

Xu Xiufeng said indifferently: "I designed the biplane model myself, so I have to test it myself."

No one can twist Xu Xiufeng, so he can only acquiesce that Xu Xiufeng boarded the biplane and fastened the safety rope.

After experiencing the failure of the monoplane, the crowd of onlookers has lost their interest at the moment.

"No fun no fun."

"I thought I could really fly, but feelings dragged me around like this."

"What's the point of that. It doesn't make any sense at all."

"I can't even fly a kite, so what's the point?"

"Then you go."

"But I want to see what the one with two layers of wings looks like."

"It should be easy to fly with two layers of wings, right?"

"Even if it flies, it doesn't make much sense. Don't you need a steam car to drag it? And...you also need a straight road that can drive fast. How can there be so many qualified road conditions in New Kyushu? Ah, isn't this a waste of time."

"There is no road to repair."

"Crazy. Just to let them run around like this, and build this kind of road everywhere?"

“…”

'Wooooooh'

Time for everyone to chat~IndoMTL.com~ The steam car started, and the two steam cars dragged the double-decker plane and drove out slowly.

Gradually, the speed is getting faster and faster.

Li Zhen and the others stood at the rear, staring closely at the slowly departing plane ahead, frowning.

I don't know if it will be successful this time.

If it still fails this time, it will encounter an unprecedented bottleneck again.

It is necessary to re-plan the fuselage to reduce the weight by at least half. Then it is necessary to exploit the potential of the radial engine again and squeeze out the maximum speed and torque.

But in fact, no matter which one it is, it is extremely difficult.

The current two models are made after overturning the original manuscript many times and designing it many times. The weight is already very light. If you still want to lose weight significantly, then the difficulty is not a little bit.

It is even more difficult to squeeze the potential of a radial engine. Now that the radial engine has not been fully developed, how can it be upgraded?

The stakes are high. Everyone held their breath.

'Wooooooh'

The speed of the steam car is getting faster and faster.

The speed of the double-decker plane is also getting faster and faster.

Xu Xiufeng looked relaxed, because Liu Jinghong only started to look up when he was two kilometers away. He is not in a hurry.

"No!"

Xu Xiufeng exclaimed and suddenly looked down.

However, the front wheel has been raised.

"Impossible, I haven't operated the joystick yet."

Xu Xiufeng exclaimed, and then looked at the distance, it was only one kilometer.

The speed is only more than 30 kilometers.

"Forty!"

The steam car in front broke a rope, and the driver of the remaining car yelled.

Xu Xiufeng took a deep breath, then held his breath, and slowly pushed the joystick up...
