As the countdown sounded, countless people in front of TV sets and mobile phones around the world couldn't help but stop everything they were doing at this moment, looked at the countdown screen, and couldn't help but read along.
In the school, the teacher leads the students.
In an office, the boss leads his employees.
In the bar, the drinkers followed the waiters.
In the restaurant, the diners forgot about the food on the table.
In such a short countdown, countless people around the world seemed to have participated.
"3, 2, 1!"
"Start!" Chen Mengchuan's calm voice fell.
In the take-off square, the spaceship Tenzhi 1 in the middle slowly emitted many lights, including red, blue, purple and green.
"......" There were some dull loud noises and trembled several times. The huge Tianzhi 1 slowly pulled out a little bit of gravitational support outer nodes from various areas of the fuselage, and then the light bloomed.
The sound of "Buzz..." went from slow to fast, and finally became a continuous sound line.
Tenzhi 1 slowly finally levitated with the continuous help of the gravity node!
As Tenzhi 1 took off, everyone couldn't help but cheer. Regardless of country, race, or skin color, everyone who saw this scene deeply blessed the spacecraft Tenzhi Technology!
After the slight dust air flow passed, Tenzhi 1 slowly flew into the sky, and began to accelerate little by little at a speed that could be discerned by the naked eye.
There was no grandeur like other rockets when they took off. Tenzhi 1 just flew steadily straight towards the sky.
The camera group pre-set at the far point quickly released the picture. In the sky under the blue sky and white clouds, Tenzhi 1 steadily broke through the air, rushed out of the clouds, and headed towards the blue sky faster and faster.
The scene was quickly switched to an altitude of 3,000 meters. Dozens of Tenzhi Technology's Little White Dragon gravity mechas were suspended in the airflow layer, and the scene of Tenzhi 1's flying was meticulously transmitted back to the ground...
Soon after, Zhao Wanyu started the camera and video recorder on Tenzhi 1, and the screen switched to the outside of Tenzhi 1 again. In the video screen, you can see that Tenzhi 1 is flying towards the sky at a very fast acceleration, breaking through layers of white clouds, and then, finally, only a vast expanse of white remains.
In Tenzhi 1, Xu Zhenglin's hand was covered by the gravity mecha, and he was holding the hand of his wife Zhang Ying tightly. The two of them could clearly feel that Tenzhi 1 was taking off. At the same time, the anti-gravity system in the room also started to activate little by little, alleviating many adverse reactions caused by the rapid vertical flight of the two people.
These reactions were very clear to them during the training, and they had experienced them many times, so they were no strangers to them. But this time, when I was actually sitting in Tenzhi 1, under the gaze of all mankind, I felt completely different. These pressures came from myself, not the effects of gravity.
"Old Zhang, how do you feel?" Xu Zhenglin asked his wife.
"It's okay. I'm 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, Old Zhang is about to enter the troposphere." A voice came out.
The speaker was a subsystem of Achen, Tenzhi 1's spaceship Artificial Intelligence "Ayu".
"Okay Ayu, thank you." Zhang Ying tried hard to calm down.
"After entering the troposphere, the temperature outside the spacecraft will continue to cool down. The spacecraft will turn on the heating system and there will be some stuffy effects. These are normal." Ayu continued to say slowly.
"Okay Ayu." Old Xu nodded inside the mecha.
On the ground, after the take-off ceremony, several experts from Tenzhi Technology began to introduce and explain the situation that Tenzhi 1 would face next. At the same time, the video screen also began to cut a lot, showing the manned inner compartment of Tenzhi 1.
In the inner warehouse, two mechas were sitting together, hand in hand, with a safety net buckle next to them to protect their whole bodies.
"Entering the troposphere!" Chen Mengchuan looked at the video and spoke slowly.
Zhao Wanyu nodded. With a lot of knowledge, she now clearly understands the troposphere, which is the layer of atmosphere structure closest to the ground. The average height is 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 Su City is located is relatively in the middle, about 11-12 kilometers.
The troposphere is the area with the strongest atmospheric convection 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 area where evaporation, clouds, rain, etc. most often occur. On average, tropospheric temperature decreases with altitude, with the temperature decreasing by approximately 0.6°C for every 100 meters of elevation. So after entering the troposphere, the temperature will quickly start to drop.
Toni looked at the video, pushed up his glasses and spoke slowly, "After officially entering the troposphere, for every 1 kilometer of altitude increase, the temperature in contact with Tenzhi 1's outer body will drop by an average of about 6.49 degrees Celsius. Explained from the first law of thermodynamics, this decrease in temperature is caused by the emergence of adiabatic cooling. When the air rises, the air pressure will drop and the air will expand. In order for the air to expand, a certain amount of work needs to be done to the surroundings, so the temperature will drop."
Everyone nodded. The current flight speed is already very fast, reaching a speed of more than 100 kilometers per hour, and it is still increasing in speed. It is expected to pass through the troposphere in 4 minutes.
The video director began to switch the lens to the external camera.
It can be seen from the external camera of Tenzhi 1 that the fuselage has begun to tremble obviously to a small extent. This is obviously caused by the collision effect of airflow. The multi-directional gravity system of Tenzhi 1 has also been fully turned on, and the flight track is constantly and rapidly adjusted in small increments to keep the fuselage on the correct track without causing orbit deviation.
During the introduction, the director switched the video screen several times to the external camera. From the constant shaking, all those paying attention could not help but feel anxious, fearing that Tenzhi 1 would be swept off the track by the air current in the troposphere.
A few minutes passed by, and Tenzhi 1's speed had increased to 170 kilometers per hour, and Artificial Intelligence Ayu reminded that it had passed the troposphere and reached the stratosphere!
"When the temperature in the external area is -57.15°C, it is expected to begin to enter the temperature recovery zone in 6 minutes. The airflow in the stratosphere is basically horizontal airflow, with very little up and down convection. There may be large gravitational fluctuations. Old Xu Old Zhang, please be mentally prepared." Ayu continued to remind.
