Doomsday Bunker Upgrade

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 known as 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 stable airflow in the stratosphere, lack of water vapor and no alternation of heat and cold, this layer was called cloudless. Once the plane flies to this height, all you can see is the sea of ​​clouds below, and only the endless blue sky overhead. And the sun is so strong that it can cause sunburn.

However, when Chen Xin and Yun 9 flew to this height together, all they could see was the darkness that was 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 extremely bad. on the other side.

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

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

Not only that, the dust and particles in the sky blocked the sunlight that should have been shining down, and it looked as if the whole world was a dim yellow, as if at the last moment of the day, the earth was about to enter darkness, but the sun was struggling to burn on the horizon. The last ray of light.

Although it is a long-lost sunshine, it gives the feeling 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.

The visibility of Chen Xin's line of sight is no more than 200 meters. If the distance between him and Yun 9 is not kept at less than 100 meters, he will even lose the trace of the plane.

Despite this, in this dim world full of dust, the distance of 100 meters still made Yun 9's figure blurred.

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

Such a situation will obviously have a great impact and damage on 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 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. It can be clearly seen that the intake volume and power of the engine have been affected. Affected, and even the propeller blades have 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, it won't last long, 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, at this time, various instruments on the plane also showed the problems encountered by the plane at this time, and many instruments have begun 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 let the whole plane start to lower in altitude.

Chen Xin kept following the plane, watching it re-enter the troposphere, took off the yellow "ribbon" lingering around him, and was surrounded by darkness again, so he shouted to the pilot through the communication channel: "Open the tailgate, I will to go in."

"Tail hatch? 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 compartment of the Yun-9 can of course be opened, and it can be opened in flight for airdrops or parachuting.

But no matter how big the brain hole of the designer who designed the aircraft was, 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 aircraft 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 someone would enter the plane on such an occasion.

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

At high altitudes, 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, let the nano-molecules that make up the helmet flow down, and asked the crew with his face exposed.

This test flight has a lot of test items, and these crew members are responsible for doing these tests.

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

As the crew members 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 height 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 report it and let them know." Chen Xin nodded, and then walked through the door inside the cabin and walked towards the cockpit.
