Chapter 432: 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.
