The black tech madman who saves the world

Chapter 176 Troposphere (13 chapters)
With the sound of the countdown, countless people around the world in front of TVs and mobile phones couldn't help but stop everything in their hands at this moment, watching the countdown screen, and couldn't help but read along.

In the school, the teacher leads the students.

In the office, the boss leads the staff.

Inside the bar, the drinkers followed the waiters.

Inside the restaurant, diners forget what's on the table.

In such a short countdown, countless people around the world seem to have participated.

"3, 2, 1!"

"Activate!" Chen Mengchuan's calm voice fell.

In the take-off square, the spacecraft Tianzhi 1 in the middle slowly emits many lights, red, blue, purple and green.

"噗...噢噌..." Several dull loud noises trembled, and the huge Tianzhi 1 slowly pulled out a little gravitational support outer node from various areas of the fuselage, and then the light bloomed.

The sound of "hum..." went from slow to fast, and finally became a continuous sound line.

Finally, Tianzhi No. 1 slowly floated under the continuous help of the gravitational node!

As Tianzhi 1 hovered and took off, everyone couldn't help but cheered, regardless of country, race, or skin color, everyone who saw this scene deeply dedicated to this spaceship of Tianzhi Technology bless!

After the slight dust flow passed, Tianzhi 1 slowly flew into the sky, and the speed began to accelerate a little at a speed that could be discerned by the naked eye.

Without the magnificence of other rockets, Tianzhi 1 just flew steadily and straightly towards the sky.

The camera group, which was pre-set at the far point, quickly released the picture. In the sky under the blue sky and white clouds, Tianzhi 1 steadily broke through the air, rushed out of the clouds, and moved towards the blue sky faster and faster. go.

The screen was quickly switched to an altitude of 3000 meters. Dozens of Tianzhi Technology's little white dragon gravity mechas were suspended in the airflow layer, and meticulously transmitted the image of Tianzhi 1 flying back to the ground...

Soon afterwards, Zhao Wanyu activated the video camera on Tianzhi 1, and the screen switched to the outside of Tianzhi 1 again. In the video screen, it can be seen that Tianzhi 1 is constantly flying towards the sky at a very fast speed Go, pierced through the layers of white clouds, and then, finally, only a piece of whiteness remained.

In Tianzhi No. 1, Xu Zhenglin's hand was covered by the gravity mecha, and he held his wife Zhang Ying's hand tightly. The two could clearly feel that Tianzhi No. 1 was taking off, and at the same time, the anti-gravity system in the room was also activated. Start a little bit to alleviate the many adverse reactions of the two people due to the rapid vertical flight.

These reactions, which they have known very clearly during the training and have experienced many times, are no strangers.But this time I really sat in Tianzhi 1, under the gaze of all human beings, the feeling is completely different. These pressures come from myself, not from the gravitational effect.

"Old Zhang, how do you feel?" Xu Zhenglin asked his wife.

"It's okay. I was a little nervous and stressed. I felt a little out of breath at first, but it shouldn't be a big problem now." Zhang Ying smiled hard.

"Old Xu, Lao Zhang is about to enter the troposphere." A voice came out.

The one who spoke was a subsystem of Achen, the artificial intelligence "Ayu" of Tianzhi 1's spacecraft.

"Ok Ayu, thank you." Zhang Ying tried to calm herself down.

"After entering the troposphere, the temperature outside the spaceship will start to drop continuously. The spaceship will turn on the heating and heating system, and there will be some stuffy effects. These are normal." Ayu continued to speak slowly.

"Okay Ayu." Old Xu nodded in the mecha.

On the ground, after the take-off ceremony, several experts from Tianzhi Technology began to introduce and explain the situation that Tianzhi 1 will face next. among.

In the inner cabin, two mechas sit together holding hands, with a safety net buckle beside them to protect the whole body.

"It's entered the troposphere!" Chen Mengchuan looked at the video screen and said slowly.

Zhao Wanyu nodded. With a lot of knowledge, she is now very clear about the troposphere, which is the layer of the atmosphere closest to the ground, with an average height of about 10 kilometers.

The height of the troposphere varies with latitude, with a maximum of about 15 kilometers at the equator and a minimum of about 8 kilometers at the poles.The area where Suzhou City is located is relatively in the middle, about 11-12 kilometers away.

The troposphere is the region where atmospheric convection is strongest and where most weather phenomena occur.80% of the water vapor in the earth's atmosphere is deposited in the troposphere, so it is also the most frequent area for evaporation, clouds, rain, etc.On average, the temperature of the troposphere decreases with height, and the temperature drops by about 100°C for every 0.6 meters of rise.So after entering the troposphere, the temperature will start to drop very quickly.

Looking at the video, Toni pushed his glasses and said slowly: "After officially entering the troposphere, every time the altitude rises by 1 kilometer, the temperature of the outer body of Tianzhi 1 will drop by about 6.49 degrees Celsius on average. The law explains that this temperature decrease is caused by the appearance of adiabatic cooling. When the air rises, the air pressure will drop and the air will expand accordingly. In order to make the air expand, a certain amount of work needs to be applied to the surroundings, so the temperature is will fall."

Everyone nodded.The current flight speed is already very fast, reaching a speed of more than 100 kilometers per hour, and the speed is still increasing. It is expected to pass through the troposphere within 4 minutes.

The video director began to cut shots to the external camera.

From the external camera of Tianzhi 1, it can be seen that the fuselage has begun to visibly tremble slightly, which is obviously caused by the collision effect of the airflow. The flight track was adjusted slightly to keep the fuselage on the correct track without any track deviation.

During the introduction process, the director switched the video screen several times to the external camera. From the constant trembling, all the people who followed could not help but feel anxious, for fear that Tianzhi 1 would be washed away from the orbit by the airflow in the troposphere .

After a few minutes, the speed of Tianzhi 1 has increased to 170 kilometers per hour, and the artificial intelligence Ayu reminded that it has passed through the troposphere and reached the stratosphere!
"When the temperature in the outer area is -57.15°C, it is expected to enter the warming area after 6 minutes. The airflow in the stratosphere is basically a horizontal airflow, with very little up-and-down convection. There may be a large adjustment of gravitational fluctuations. Old Xu Zhang, you should be mentally prepared." Ayu continued to remind.

　Thank you book friend [Xiaoguang Chujue] for your reward, thank you for your support.
