The two pilots had expressionless faces. They had experienced this kind of flight too many times and it didn't matter at all. They had taken too many people, and they didn't have much desire to talk. Most of the people they had taken might not be able to embark on this journey in the end.
The road, who knows.
The plane took off normally, and all technical movements were the same as those of ordinary civil aircraft; just like in the tutorial, the captain Tristan did not use any mental power to mobilize the traveling energy during this process.
Because in theory, the air below 20,000 meters is dense, which is the process in which the body's fluid mechanics plays the greatest role. In this process, turning on the spiritual energy power has limited help to the attributes of the aircraft. On the contrary, it will affect the control of the aircraft due to the additional power added.
.
Of course, the cornerstone of this theory is based on the premise that the mental power of space airliner pilots is generally around 100 len. For someone like Bei Haiyang, whose mental power is close to 500 len, the additional planetary energy may be
It's not optional.
Of course, power is power, and control is control. It is better for an aircraft to fly on a single energy source for better control. Hybrid power will cause a lot of operational troubles, which is unnecessary.
The troposphere is the lowest layer of the atmosphere, close to the earth's surface. Its thickness is about 10 to 20 kilometers. It is the most economical and safest layer for civil aviation aircraft to fly.
The plane kept climbing at an angle of elevation, and soon crossed the troposphere and reached the stratosphere. The stratosphere refers to the layer above the troposphere, up to 50 kilometers above sea level, about 20 to 50 kilometers from the earth's surface, and the airflow is mainly horizontal.
Directional movement, convection phenomena weaken, also known as the stratosphere.
The stratosphere is still suitable for aircraft navigation, but generally civilian aircraft do not need to fly so high, but some military aircraft can easily reach this height!
This modified 959 space airliner has basically no load and no fuel burden, so it can quickly climb to the stratosphere with the help of its four engines, but it starts to feel difficult as it continues to climb!
From now on, traditional fossil combustion engines begin to become less effective as the air begins to slowly become thinner and power decreases.
At an altitude of 20 to 30 kilometers, oxygen molecules form the ozone layer under the action of ultraviolet rays, which acts like a barrier to protect life on earth from the attack of solar ultraviolet rays and high-energy particles.
Bei Haiyang noticed that after the plane crossed the ozone layer, Captain Tristan began to use his mental power to mobilize planetary energy to add power to the plane! Without it, he would not be able to climb up!
During this time period, which is the most dangerous stage of separation of the space plane, the power method is the most complex hybrid power method. It has four traditional engines and planetary energy. Under the combined effect, it pushes the huge aircraft to fly higher and higher.
Flying faster and faster.
During this process, the human body begins to feel a slight weightlessness, and the feeling becomes more and more obvious that the body is completely restrained in the seat because of the seat belt.
There is a common misunderstanding here. Many people think that weightlessness only occurs when entering space. This is wrong!
Weightlessness has nothing to do with height!
Astronauts are weightless in space not because of how high they are above the ground, but because all the gravity they feel is provided to the centripetal force, allowing them to orbit the earth. Even on the ground, as long as you can reach the first cosmic speed,
That is, at 7.9 kilometers/second, you can still fly close to the ground without falling, so you become weightless.
Of course, you can't do this, because there is air resistance, and the aircraft will be burned to ashes long before it reaches this speed!
Bei Haiyang and the others now feel weightless, not because they are tens of kilometers above the ground, but because at this altitude, the air begins to become thinner and the resistance is greatly reduced, even if the overall power of the aircraft is even with the blessing of planetary energy.
Still falling, but the plane's speed keeps increasing!
This is the difference between the atmosphere and space. Without air resistance, even a tiny bit of power can make objects accelerate very quickly!
When the plane reached an altitude of 50 kilometers, the four engines that had been continuously reducing their output could no longer keep running. The thin air prevented them from burning normally, even though these four engines were specially designed and are dedicated to low-air
Density engine, this height is also the limit they insist on!
The hybrid power stage is over, and now it enters the stage where pure spiritual power is used to mobilize planetary energy to provide power!
Above the stratosphere is the mesosphere, which is about 50 to 85 kilometers away from the earth's surface. The air here is already very thin. The prominent feature is that the temperature decreases rapidly with increasing altitude and the vertical convection of the air is strong.
Driven by planetary energy, the aircraft is infinitely close to the first cosmic speed!
Now, they are very close to theoretical space!
When the speed of the plane exceeded the first cosmic speed, Bei Haiyang only felt his body light up. He no longer had any restraint. He could float freely after loosening his seat belt. At this time, their height from the ground had reached 100 kilometers.
, entering the warm layer.
The warm layer is about 100 to 800 kilometers away from the earth's surface. The most prominent feature of the warm layer is that when the sun shines on it, the ultraviolet rays in the sun are absorbed by the oxygen atoms in the layer, so the temperature rises, so it is called the warm layer.
, also called the ionosphere.
Here is the edge of space! Starting 200 kilometers further up, it is the so-called low-Earth orbit! This near-circular orbit from 200 kilometers to 2,000 kilometers is the home of countless satellites!
It is also the flight path of the space shuttle!
Under Tristan's control, the plane continued to climb, but the climb was now very easy. He even had to weaken his mental power to mobilize energy, just to prevent the speed from accelerating endlessly.
Theoretically, if he keeps going all out like this, it will only be a matter of time before he breaks through the speed of the second and third universes!
At this point, the flight demonstration has been half completed and half taken off; when they are flying around the earth at 300 kilometers, they have actually turned themselves into a satellite, a satellite that can change its attitude at any time.
!
Different from flying in the atmosphere, flying in the earth's low-Earth space orbit also requires the control of a flight control center to monitor the trajectory of the space plane and guide them to avoid the fixed satellite orbit ahead and other space planes!
The only difference is that there are countless traditional flight control centers on the ground, but there are only two space flight control centers, the American control center in the western hemisphere, and the Chinese control center in the eastern hemisphere!
In fact, with the current number of satellites and the fact that there are only a few space planes, the space flight control center basically has nothing to do; but if we consider that in the future, satellite groups will continue to increase and space planes will continue to prosper, such a flight control center will still
Must have!
Set up the system first, and then slowly gain experience.
