Chapter 433

Stratosphere is one of the layers of the atmosphere, which 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 in the bottom layer and hot in the upper layer.

This is just opposite to the upper cold and lower heat in the troposphere, and it is precisely because of this that the stratosphere is relatively stable, and there is no conventional convective activity and so connected air flow.

Because of this characteristic of stratosphere, it is also called stratosphere. The temperature and airflow are relatively stable, so it is an ideal place for aircraft flight.

Most of the world's civil aircraft are cruising in the stratosphere to avoid the changeable weather and airflow in the troposphere, so as to maintain flight stability.

In the past, because of the stable air flow, lack of water vapor and no alternation of cold and heat in the stratosphere, this layer can be called cloudless. Once the plane flies to this height, it can only see the sea of clouds below, while there is only endless blue sky and strong sun that can burn people above.

However, as soon as Chen Xin and Yun 9 took off at this height, the only thing he could see was that it was as dark as a strong sandstorm.

Chen Xin used to work in the imperial capital of Yan state. At that time, it was the most serious haze problem in the imperial capital. Once, when Chen Xin went to work, the weather was extremely bad. He stood on the side of the road and could not see the other side nearby.

If it wasn't for a huge outdoor electronic screen shining in a shopping mall on the other side at that time, Chen Xinzhen thought there was nothing on the other side.

And the stratosphere at this time, and Chen Xin's memory of the extremely bad weather in the imperial capital.

Not only that, the dust and particles all over the sky block the sunlight that should have been shining down. Looking up, it seems that the whole world is a yellow, just like the last moment of the day, the earth is about to enter the darkness, but the sun struggles to burn the last ray of light on the horizon.

Although it is a long lost sunshine, it gives people the feeling that a world has come to an end, even the sun has burned out, and the whole world has turned into a desert.

However, this is not waste soil, but at an altitude of 12000 meters.

The visibility of Chen Xin's line of sight does not exceed 200 meters. If the distance between Chen Xin and Yun 9 is not kept at less than 100 meters, he will even lose the trace of the plane.

Even so, in this dusky world full of dust, the distance of 100 meters still blurs Yun 9's figure.

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

This situation will obviously cause great impact and damage to the aircraft. Even if Chen Xin installed air filters on the aircraft engine, he will not last long in such an environment.

Sure enough, it's only a short time since the plane entered the stratosphere. In Chen Xin's field of vision, all the data of the plane have begun to turn red. Especially for the engine, it's obvious that the intake volume and power of the engine have been affected, and even the propeller blades have begun to vibrate.

Seeing this situation, Chen Xin decisively connected the plane's communication channel, and yelled to the pilot in the channel: "the plane's state is affected by the dust, and it won't last long. Lower the altitude immediately!"

"Academician Chen? How do you know The pilot suddenly heard Chen Xin's voice and was surprised. He wondered how Chen Xin knew the state of the plane.

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

Chen Xin has been following the plane, watching it re-enter the troposphere, take off the lingering yellow "Ribbon" and be surrounded by darkness again. Then he yelled to the pilot through the communication channel: "open the tail hatch, I want to go in."

"The hatch? Academician Chen, are you outside? How did you get here? " The pilot was completely shocked. When he was flying the plane for the first time, he heard someone tell him to open the cabin door and let people outside come in.

This is a plane, not a car! No one ever said to open a door to let people in when a plane is flying in the sky.

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

As a transport aircraft, the tail cabin of yun-9 can be opened, and it can be opened in flight for airdrop or parachute jump.

But no matter how big the brain hole of the original designer was, I'm afraid I didn't think that someone would be able to enter the plane in the sky through the open hatch.

However, with flying nano armor, Chen Xin can really get into the plane through the open cabin door during the flight.

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

Several crew members in the cabin were surprised to see Chen Xin in nano armor. No one thought that someone would enter the plane on such an occasion.Seeing Chen Xin entering the plane, the crew quickly closed the hatch again.

It's not easy to open the cabin door at high altitude. The pressure difference inside and outside the cabin will cause pressure loss inside the cabin.

"How many items have not been tested in this test flight?" Chen Xin opened the helmet's mask and let the nano molecules that make up the helmet flow down. He showed his face and asked the crew.

There are many test items in this flight test, and these crew members are responsible for these tests.

"A lot of high-altitude flight tests have not been done. The plane just entered the stratosphere for a period of time, which is not enough." A crew member looked through the record board in his hand and reported to Chen Xin.

As the crew of this test flight, they all met Chen Xin before taking off, and naturally knew this young and shameful academician.

Chen Xin nodded and said to them, "in addition to the test that you have to fly to the stratosphere, do the other tests like this. Tell the pilots to keep flying at the altitude of the troposphere instead of rising to the stratosphere."

"Yes, academician." The crew answered, but asked Chen Xin, "do you need to tell the academician on the ground about your coming up?"

"Let them know." Chen Xin nodded, then went through the door inside the cabin and toward the cockpit.
