"Take off!"

"Take off!"

A loud shout spread throughout the airport. As the flag bearer turns the red flag into a green flag.

Peng's pilot slammed the push rod and then dropped the brakes of the take-off and lander.

'Hum-'

The sound of the engine and the propeller was mixed, and Peng's huge body burst out with a rapid starting speed.

It's not proportional to its size at all.

The burly body of more than 20 meters makes people always think that its speed should be very heavy and slow. But this is not the case, it is unusually fast, not much faster than the Grasshopper.

In just twelve seconds, the speed has already exceeded a hundred kilometers.

The crowd almost saw a bright afterimage streak across the airport, rolling up dust and filling the sky. At a distance of two kilometers, the nose of the plane was suddenly raised, and then it flew upwards in the sky with an oblique stab.

Li Zhen stood up and picked up the binoculars to look.

Jiang Tianqi also stood up in surprise: "So fast!" ”

The Kyushu Academy of Sciences and others all stood up and picked up their binoculars to look at the sky.

Liu Jinghong had a proud look on his face, and he was particularly satisfied with the performance of his works.

In the crowd, Xun Jiayuan's face was also full of ecstasy at this time, seeing that Peng Shi had taken off so beautifully, he muttered excitedly: "I designed it, I designed it." This is what I designed. I am the deputy leader of the design team, which is the ...... I participated in the design and development Pengshi, I'm proud of you! ”

'Aang-'

The sound pierced the heavens and the earth.

Piercing through the clouds, the roc bird flew higher into the sky.

It's flexible and not as clumsy as expected. Maybe the burly body is an illusion, and when it enters the blue sky, you will find that it is swift and fast.

Five hundred meters!

It began to circulate around Laoshan County.

The pilot's face was full of excitement: "Excellent." This plane is outstanding. It is more than capable of sailing thousands of miles. I feel that it is too light, so much power, this kind of power is enough to lift a dozen tons of weight, right? ”

It's starting to rise.

Six hundred meters.

Seven hundred meters.

Eight hundred meters.

One kilometer.

Fifteen hundred meters.

Two thousand five hundred meters.

Eventually, it entered the air at an altitude of 3,000 meters.

And at this time, the pilot's face was full of panic, and he felt that the plane began to produce violent turbulence. Sitting in the driver's seat, I felt like a sifting chaff. The ass is numb.

"It's not going to fall apart, is it?"

With a mutter, he glanced at the dashboard, and the speed had already exceeded 210 kilometers per hour.

He didn't expect Peng Shi to be so fast. But he didn't know how strong Peng's style was.

"I remember reading a point made by Li Shi before, when the aircraft is driving at high speed at low altitude, the feeling of bump will increase. Because the troposphere is at an altitude of more than 3,000 meters, the air in the troposphere is extremely unstable. Aircraft travel in the troposphere, the speed decreases, fuel consumption increases, and the danger increases. ”

The pilot muttered: "And if the plane breaks through ten kilometers at an altitude of ten kilometers, it will break through the troposphere and enter the stratosphere." The sky is clear in the stratosphere, and all the dark clouds, rain, and lightning will be at your feet. Fuel consumption decreases, the speed becomes faster, and the flight tends to be stable. But entering the stratosphere does not allow you to break through the technology. Oxygen is thin in the stratosphere, and atmospheric pressure increases. The Peng type does not have a device to resist atmospheric pressure......"

He looked up at the higher sky, and a hint of yearning appeared in his eyes: "I can't go up." Li Shi once wrote a book about the sky, in which he talked about atmospheric pressure. If you want to get a plane into the stratosphere, you have to keep the plane absolutely sealed, otherwise people will die under atmospheric pressure. However, if there is an absolute seal and no decompression facilities, the imbalance between the pressure inside the aircraft and the external pressure will explode. ”

"I'd love to take a look."

Constantly talking to himself, the pilot's heart began to stir, he had a riotous heart.

Give it a try!

The pilot gritted his teeth, suddenly raised the control stick, the wings undulated, and Peng immediately headed higher into the air.

Farther and farther away.

Li Zhen frowned, looked at Peng Shi in the telescope who was heading higher, and asked sideways, "What is he going to do?" ”

"I don't know."

"Master Li, is he going to a higher place?"

Li Zhen's face changed: "He doesn't even have an oxygen cylinder, how can he go to a higher place?" Let him down. ”

"The ground crew immediately sent a report to him to lower the altitude."

Peng plane.

The pilot received the order, looked at the sky with a hesitant face, and fantasized about the beauty of that height. But he had to carry out the order, lower the altitude and prepare to land.

The items tested have all been tested, and the Peng-style is basically stable. Yes, it can be used normally.

But the pilot was in pain, and he felt that for the time being, the Peng-style was the only flying machine that could challenge the stratosphere. It is stable, strong and strong. Better sealed than other aircraft, it can actually challenge the stratosphere.

But I had to give up......

'Hum-' louder and louder. The plane began to land.

The old pilot's technique was in place, landing on the runway with great precision, and then stopping steadily at the starting place, with an error of only one meter.

Jumping off the plane, a group of technicians immediately walked over and asked him about various data.

Li Zhen watched this scene from afar, with thoughtful eyes in his eyes.

Liu Jinghong asked: "Master Li, is it possible to try manned flight?" Let's just try it all at once today. ”

Li Zhen nodded: "Hmm." Go ahead. People all use dummies, are the dummies you prepared before? ”

"Ready. All of them were dummies sewn from sandbags, each weighing an average of one hundred and fifty pounds. ”

"Let's use thirty-five one hundred and fifty pounds of dummies for the test. That's right......"

Liu Jinghong stopped: "What's the matter, Master Li?" ”

Li Zhen said lightly: "Change the pilot." ”

"Huh?"

Liu Jinghong was stunned: "Why? ”

"There's no why, if you want to change one, you'll change it. Where is all this nonsense? Go ahead. ”

Liu Jinghong nodded and hurriedly went to do it. He looked at the pilot who was questioned with some confusion, and couldn't understand why Li Shi personally ordered him to be replaced. Was it because he had just flown higher?

Isn't flying to a higher place testing the performance of the aircraft? Why?

Liu Jinghong didn't know.

Li Zhen felt a kind of crazy heart from this pilot, this crazy heart was his own, and Qin Enze, who he once valued the most, had it.

This kind of crazy heart can't be said to be bad. But it is not suitable for the current occasion. The pilot in front of him is obviously regardless of the occasion.

Li Zhen asked, "What's the name of that pilot?" ”

"Back to Division Li, he is the deputy captain of the first team of the Laoshan flight formation. It's called Gao Zhihang. ”

"Let him come, I've got something to ask him."

"Yes."
