Chapter 434: board the plane

The stratosphere is one of the layers of the atmosphere, located above the

troposphere and below the middle layer. Because it absorbs a lot of

ultraviolet radiation, the temperature of this layer is cold in the bottom

layer and hot in the upper layer.

This is just the opposite of the upper and lower troposphere's cold and lower

heat, and it is precisely because of this that the stratosphere is relatively

stable, without conventional convective activity and such connected airflow.

Because of this characteristic of the stratosphere, it is also called the

stratosphere. The temperature and airflow are relatively stable, making it an

ideal place for airplanes to fly.

The vast majority of civil airliners in the world also cruise in the

stratosphere to avoid the changeable weather and air currents in the

troposphere, thereby maintaining stable flight.

In the past, because of the stable air currents in the stratosphere, lack of

water vapor and no alternation of cold and heat, this layer can be said to be

cloudless. Once the plane flies at this altitude, all you can see is the sea

of clouds below and the endless blue sky above your head. And the sun is so

strong that it can burn people.

However, when Chen Xin and Yun 9 flew to this height together, what was

visible was only as dark as a strong sandstorm.

Chen Xin used to work in the imperial capital of Yan Country. At that time,

the imperial capital was at the time when the smog problem was the most

serious. Once Chen Xin went to work when the weather was extremely bad. He

could not see him close by when he was standing on the side of the road. On

the other side.

If it weren't for a large outdoor electronic screen gleaming in a shopping

mall on the other side, Chen Xin really thought there was nothing on the

opposite side.

At this time, the stratosphere was a fight against the extremely bad weather

in the capital city in Chen Xin's memory.

Not only that, the dust and particles in the sky blocked the sunlight that

should have been shining down, and I looked up as if the whole world was a dim

yellow, just like the last moment of the day, the earth is about to enter

darkness, but the sun is struggling to burn on the horizon. Give the last ray

of light.

Although it is long-lost sunlight, it feels like a world has come to an end,

even the sun has burned out, and the whole world has turned into a wasteland

and desert.

However, this is not wasteland, but an altitude of 12,000 meters.

The visibility of Chen Xin's line of sight is no more than 200 meters. If it

weren't for the distance between him and Yun 9 to be kept at less than 100

meters, he would even lose sight of the plane.

Nevertheless, in this dusty and yellow world, the distance of one hundred

meters still made Yun 9's figure blurred.

Because of the disturbance of the airflow, a yellow cover gradually appeared

around the aircraft, which was a scene of dust flowing along with the airflow

on the surface of the aircraft.

Obviously, such a situation will cause great impact and damage to the

aircraft. Even if Chen Xin installed an air filter on the aircraft engine, it

would not last long in such an environment.

Sure enough, the aircraft entered the stratosphere for only a short period of

time, and the various data of the aircraft in Chen Xin's field of vision have

already begun to become popular, especially in the engine part. It can be

clearly seen that the intake and power of the engine have been affected. The

impact, even the blades of the propeller have begun to vibrate.

Seeing this situation, Chen Xin decisively connected to the aircraft's

communication channel and shouted to the pilot in the channel: "The state of

the aircraft is affected by dust. It won't last long, so immediately lower the

altitude!"

"Academician Chen? How do you know...?" The pilot was surprised when he heard

Chen Xin's voice. He was a little surprised how Chen Xin knew the state of the

aircraft.

However, the various instruments on the aircraft also showed the problems

encountered by the aircraft at this time. Many instruments have already

started to alarm. Before, the pilot wanted to test the limits of the aircraft

in this state under pressure.

But now Chen Xin ordered him to lower the altitude, and the pilot did not

deviate from his order, pressing the joystick to make the entire plane begin

to lower the altitude.

Chen Xin kept following behind the plane, watching it re-enter the

troposphere, taking off the lingering yellow "ribbon" around him, and being

surrounded by darkness again. Only then did he shout to the pilot through the

communication channel: "Open the tailgate door, I Go in."

"Tail hatch? Academician Chen are you outside? How did you fly up?" The pilot

was completely shocked. When he flew the plane for the first time, he heard

someone say that he should open the hatch to let people in.

This is an airplane, not a car! No one has ever said that when a plane is

flying in the sky, a door should be opened to let people in.

But after repeated confirmations, Chen Xin still insisted on letting him open

the door, and the pilot had to follow Chen Xin's instructions to open the

tailgate of Yun9.

As a transport aircraft, the tail compartment of the Y9 can of course be

opened, and it can be opened in flight for airdrop or parachuting.

But even if the designer who originally designed the aircraft had a big brain,

I am afraid that someone would be able to enter the aircraft in the sky

through the opened tailgate.

But with nano-armor that can fly, Chen Xin can indeed enter the aircraft

through the open door during the flight.

Although it looked similar to the scene in the movie, Chen Xin did fly in when

the tailgate of the Yun9 was opened and landed firmly in the cabin of the

Yun9.

Several crew members in the cabin saw Chen Xin wearing a nano-armor with a

surprised expression on his face. No one thought that someone would enter the

plane on this occasion.

Seeing Chen Xin entering the plane, the crew hurriedly closed the tailgate

door again.

At high altitude, opening the cabin door is not a simple matter. The pressure

difference between inside and outside the cabin can cause pressure loss in the

cabin.

"How many items have not been tested in this test flight?" Chen Xin opened the

helmet's visor, letting the nanomolecules that make up the helmet flow down,

UU reading www.uukānshu.com showed his face and asked the crew member.

There are many test items in this test flight, and these crew members are

responsible for doing these tests.

"Many high-altitude flight tests were not done. The plane only entered the

stratosphere for a while, and there was not enough time." A crew member

flipped through the record board in his hand and reported to Chen Xin.

As the flight crew of this test flight, they had all met Chen Xin before

takeoff, and they naturally knew this young and unspeakable academician.

Chen Xin nodded and said to them: "Except for tests that must fly to the

stratosphere, do the same for other tests. Tell the pilots to keep flying at

the altitude of the troposphere instead of ascending to the stratosphere."

"Yes, academician." The crew member responded, but then asked Chen Xin: "Do

you need to tell the ground academician about your coming up?"

"It's okay to let them know." Chen Xin nodded, then walked through the door

inside the cabin and walked towards the cockpit.
