Chapter 394
The two pilots were expressionless. They have experienced this kind of flight too many times, so it doesn't matter at all. They have brought too many people, and they don't have much desire to talk; way, who knows.

The plane took off normally, and all the technical actions were the same as those of ordinary civil aviation aircraft; as in the tutorial, the captain Tristan did not use any mental power to obtain the energy during this process.

Because in theory, the dense air below [-] meters is the process in which the fluid mechanics of the body play its greatest role. During this process, turning on the spiritual energy power will not help the aircraft's attributes, but will affect the control of the aircraft due to the additional power. .

Of course, the cornerstone of this theory is based on the premise that the pilots of space airliners generally have a mental strength of around [-] Lures. For someone like Bei Haiyang whose mental power is close to [-] Lures, the extra planetary energy may It is not optional.

Of course, the power belongs to the power, and the control is the control. It is better for an aircraft to fly under a single energy source and it is easier to 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 surface of the earth, and its thickness is about 10 to 20 kilometers. It is the most economical and safest flight layer for civil aviation airliners.

The plane has been climbing at an elevation angle, and soon crossed the troposphere and came to the stratosphere.The stratosphere refers to the layer above the troposphere until it is 50 kilometers above sea level, about 20 to 50 kilometers away from the earth's surface. The airflow mainly moves in the horizontal direction, and the convection phenomenon is weakened. It is also called the stratosphere.

The stratosphere is still suitable for aircraft to fly, but ordinary civil aircraft do not need to fly so high, but some military aircraft can easily reach this height!

This modified 959 space passenger plane has basically no load and no fuel burden, so it can quickly climb to the stratosphere under the push of four engines, but it starts to feel difficult when it continues to climb!
From now on, traditional fossil combustion engines are less useful as the air slowly gets thinner and power drops.

At a height of 20 to 30 kilometers, oxygen molecules form the ozone layer under the action of ultraviolet rays, which acts like a barrier to protect organisms on the 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 spiritual power to transfer planetary energy to boost the plane!If you don't add it, you can't climb it!
During this time period, which is the most dangerous breakaway stage of the space plane, the power mode is the most complicated hybrid power mode. There are not only four traditional engines, but also planetary energy. Fly faster and faster.

During this process, the human body begins to feel a slight weightlessness, and it becomes more and more obvious that the body is completely restrained by the seat belt.

There is a common misunderstanding here. Many people think that weightlessness is a phenomenon that occurs only when entering space. This is wrong!
Weightlessness has nothing to do with altitude!
Astronauts are weightless in space not because of how high they are from the ground, but because all the gravity they feel is provided to the centripetal force, making them orbit the earth.Even on the ground, as long as you can reach the first cosmic speed, which is 7.9 km/s, you can fly close to the ground without falling down, so you will be weightless.

Of course, you can't do this, because of air resistance, before reaching this speed, the aircraft will burn to slag!

Bei Haiyang and the others feel weightless now, not because they are tens of kilometers away from the ground, but at this height, the air begins to become thinner, and the resistance is greatly reduced, even if the overall power of the aircraft is supported by planetary energy. Still descending, but the speed of the plane has been increasing!

This is the difference between the atmosphere and space. Without air resistance, even a negligible amount of power can make objects accelerate rapidly!
When the plane reaches an altitude of 50 kilometers, the four engines that have been continuously reducing their output can no longer keep running, and the thin air prevents them from burning normally, even though these four engines have been specially designed and are dedicated low-air Density engine, this height is also the limit they insist on!

The stage of hybrid power is over, and now it enters the stage of pure spiritual power to transfer planetary energy to provide power!

Above the stratosphere is the middle layer, 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 the increase of altitude, and the vertical convection of the air is strong.

Driven by planetary energy, the plane is infinitely approaching the first cosmic speed!

Now, they are very close to the theoretical space!

When the speed of the plane exceeds the first cosmic speed, Bei Haiyang only feels light in his body, no longer has any binding force, and he can float freely when he loosens the seat belt; at this time, they have reached a height of 100 kilometers from the ground , into the warm layer.

The warm layer is about 100 to 800 kilometers above the earth's surface.The most prominent feature of the warm layer is that when the sun shines, the ultraviolet rays in the sunlight 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 is the so-called low-Earth orbit!The nearly circular orbit from 2 kilometers to 2 kilometers is the home of countless satellites!

It is also the path of the space plane!
Under Tristan's control, the plane continued to climb, but the climb was already very easy now, and he even had to weaken his mental power to obtain energy, just to prevent the speed from accelerating endlessly.

Theoretically, if he has been going all out like this, it will be a matter of time before he breaks through the second and third cosmic speeds!

At this point, half of the follow-up demonstration has been completed, and half of the take-off; when they fly around the earth at 300 kilometers, they have actually turned themselves into a satellite, a satellite that can change its attitude at any time !

Unlike flying in the atmosphere, flying in Earth's near-Earth space orbit also requires the control of the flight control center to monitor the trajectory of space planes and guide them to avoid fixed satellite orbits 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 US control center in the western hemisphere, and the Hua country control center in the eastern hemisphere!
In fact, with the current number of satellites and the fact that there are very few space planes, the space flight control center basically has nothing to do; Must have!

Build the system first, and then slowly explore the experience.
