Doomsday Bunker Upgrade Chapter 432: Get on the plane

The stratosphere is one of the layers of the atmosphere. It is located above the troposphere and below the middle layer. Because it absorbs a lot of ultraviolet radiation, the temperature of this layer is cold at the bottom and hot in the upper layer.

This is just the opposite of the troposphere's upper cooling and lower heating, and it is precisely because of this that the stratosphere is relatively stable, without regular 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 aircraft to fly.

The vast majority of civil airliners in the world are also cruising in the stratosphere to avoid the changeable weather and airflow in the troposphere, so as to maintain a stable flight.

In the past, because of the steady airflow in the stratosphere, lack of water vapor and no alternation of heat and cold, this layer was called cloudless. Once the plane flew to this height, all you could see was the sea of ​​clouds below, and only the sea of ​​clouds overhead. Endless blue skies and sunburns strong enough to burn.

However, when Chen Xin and Yun 9 flew to this height together, the only thing that could be seen was the darkness like a strong sandstorm.

Chen Xin used to work in the imperial capital of the Yan Kingdom. At that time, the imperial capital was the worst time for the smog problem. Once when Chen Xin went to work, the weather was so bad that he could not see it from the side of the road. The other side is close at hand.

If it wasn't for a large outdoor electronic screen shining brightly in a shopping mall on the other side, Chen Xin really thought there was nothing on the other side.

And the stratosphere at this time is comparable to the extremely bad weather in the imperial capital that Chen Xin remembered.

Not only that, but the dust and particles in the sky block the sunlight that should be shining down, and when you look up, it seems that the whole world is a dim yellow, as if at the last moment of the day, the earth is about to enter darkness, but the sun is struggling. The last ray of light burned on the horizon.

Although it is a long-lost sunshine, it gives the impression that 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 kilometers.

Chen Xin's line of sight does not exceed 200 meters of visibility. If the distance between him and Yun 9 is not maintained at less than 100 meters, he would even lose track of the plane.

Nevertheless, in this dusky world full of dust, the distance of 100 meters still makes Yun 9's figure blurred.

Because of the disturbance of the airflow, a yellow cover gradually appeared around the aircraft, which is a scene of dust flowing along with the airflow on the surface of the aircraft.

Such a situation will obviously cause great impact and damage to the aircraft. Even if Chen Xin installed an air filter on the aircraft engine, he would not be able to last long in such an environment.

As expected, the plane only flew for a short period of time in the stratosphere, and all the data of the plane in Chen Xin's field of vision had already begun to turn red, especially the engine part, where the intake volume and power of the engine can be clearly seen All were affected, and even the blades of the propellers had begun to vibrate.

Seeing this situation, Chen Xin decisively connected to the communication channel of the plane, and shouted to the pilot in the channel: "The state of the plane is affected by the dust, and it won't last long, so lower the altitude immediately!"

"Academician Chen? How do you know...?" The pilot was shocked when he heard Chen Xin's voice. He was a little surprised how Chen Xin knew the status of the plane.

However, the various instruments on the plane also showed the problems encountered by the plane at this time. Many instruments have already started to alarm. Before, the pilot wanted to test the limit of the plane in this state under pressure.

But now Chen Xin ordered him to lower the altitude, and the pilot did not disobey his order. He pressed the lever and the whole plane began to lower altitude.

Chen Xin had been following the plane, watching it re-enter the troposphere, took off the yellow "ribbon" that lingered around him, and was surrounded by darkness again, so he shouted to the pilot through the communication channel: "Open the tailgate Open, I'm going in."

"The tailgate? Academician Chen, are you outside? How did you fly up?" The pilot was completely shocked. It was the first time he heard someone tell him to open the hatch to let people outside come in. .

This is an airplane, not a car! No one ever said let the plane fly in the sky and open the door to let people in.

But after repeated confirmation, Chen Xin still insisted that he open the door, and the pilot could only open the tailgate of the Yun-9 according to Chen Xin's instructions.

As a transport aircraft, the tail cabin of the Y-9 can of course be opened, and it can be opened during flight for airdrops or parachuting.

But no matter how big the brains of the designer who designed the aircraft were, he probably never thought that someone would be able to enter the aircraft from the sky through the open tailgate.

However, with the nano-armor that can fly, Chen Xin can indeed enter the plane through the open hatch during the flight.

Although this looks similar to the scene in the movie, when the rear hatch of the Yun-9 was opened, Chen Xin did fly in and landed firmly in the cabin of the Yun-9.

Several crew members in the cabin saw Chen Xin, who was wearing nano-armor, with surprised expressions on their faces. No one thought that anyone would enter the plane under such circumstances.

Seeing that Chen Xin entered the plane, the crew hurriedly closed the tailgate again.

In high altitude, it is not a simple matter to open the cabin door. The pressure difference between the inside and outside of the cabin can cause pressure loss in the cabin.

"How many items have not been tested in this test flight?" Chen Xin opened the visor of the helmet, letting the nano-molecules that make up the helmet flow down ~IndoMTL.com~ and asked the crew.

There are a lot of test items on this test flight, and these crew members are responsible for doing these tests.

"There are many high-altitude flight tests that have not been done. The plane has only entered the stratosphere for a while, and the time is not enough." A crew member flipped through the scoreboard in his hand and reported to Chen Xin.

As the flight crew of this test flight, they had all met Chen Xin before takeoff, so they naturally knew this young and outrageous academician.

Chen Xin nodded and said to them: "Except for the test that must fly to the stratosphere, let's do the other tests. Tell the pilot to maintain the flight at the altitude of the troposphere, and there is no need to ascend to the stratosphere."

"Yes, academician." The crew responded, but then asked Chen Xin, "Do you need to tell the ground academician what you came up with?"

"Let's make a report and let them know." Chen Xin nodded, then walked through the door inside the cabin and walked towards the cockpit.
