This is Bei Haiyang's first time in space. It feels very novel and familiar.
He had been here twice before, but he had borrowed Mr. Bei's body. There was still a big difference between cats and humans in terms of senses.
The entire take-off process took 50 minutes! It is estimated that the re-entry into the atmosphere will take at least the same time, maybe more! If coupled with the increase in weight after carrying passengers, the time will be extended, as well as some inevitable large and small things in the process.
In this situation, the time to enter and exit the atmosphere is at least 3 hours!
In other words, in normal aviation, there is no need to adopt such a method to shorten the flight time within 3 hours. The shorter the flight, the more inappropriate it is! Only routes with a flight duration of more than 5 hours can adopt the space roaming method.
Significant!
Specifically, for current ordinary flights, it only makes sense to use space roaming for cross-continental and trans-oceanic routes. It will not be possible to fly from New York to the East China Sea in one hour. The minimum guarantee is 3 hours, which is unbeatable.
From this perspective, the impact on the general aviation industry is not as big as imagined. At least short and medium distances can be preserved, and it is economical, affordable and safe.
He has realized that the biggest business opportunity for space roaming may not lie in traveling to different parts of the earth, but outside the earth!
For example, the moon?
From a technical point of view, from the airport takeoff to the early stratosphere, the range below 30 kilometers altitude is not a big control problem, because this is the range where the traditional engine and wing effects come into play. With a little training, any civil aviation pilot can
It can be done, but it is only twice as high as the training altitude of normal navigation. Under the premise of reducing the load and modifying the engine, you only need to hold the joystick and push the throttle to the bottom.
The difficulty is that after passing through the ozone layer of the stratosphere, the altitude is about 30 kilometers. At this time, due to the thin air, the output of the traditional engine is greatly reduced, and it can no longer maintain the acceleration of the aircraft; at this time, adding mental control of planetary energy power is the key.
!
The area with an altitude of 30 kilometers to 50 kilometers is the most dangerous, because it is a hybrid power system. The pilot must not only control four traditional engines, but also control his mental power to mobilize planetary energy. How to find a suitable balance among them?
Point is the most important thing!
The key is that although the air is thin at this time, it still exists, so the rudder surfaces of each wing are still functioning, but the effect is not as great as below! In this case, how to reasonably control the attitude is a big problem!
What's even worse is that the entire control process can only be completed by one person! This is not something that can be coordinated! Cooperation between people requires tacit understanding, and there must be a delayed understanding process, and synchronization is impossible.
In this dangerous area, the machine may overturn at any time!
Only one person can come! Because if one person is alone, he will have a consistent grasp of the situation of the entire aircraft and can react instantly!
After reaching the middle level after reaching an altitude of 50 kilometers, the traditional engine completely failed and shut down, and the influence of air and fluid was negligible. At this time, the operation began to become simple again, and it was purely a spacecraft pilot's operation method!
Therefore, the focus of the future assessment is probably between 30 kilometers and 50 kilometers, which is the key to determining whether a takeoff is successful.
After understanding this, things became simpler. At least for Bei Haiyang, he no longer needed to take off with the plane.
Captain Tristan did not stay long in the 300-kilometer orbit. The beautiful earth under the plane was already familiar to him. After contacting the ground, he chose a path, reduced the speed, and began to lower the orbit in preparation for reentry into the atmosphere.
At this time, the power provided by mental power to mobilize planetary energy is no longer forward, but reverse thrust similar to a traditional engine! But such reverse thrust needs to be controlled very precisely, so that the orbit can be gradually lowered rather than plunged headlong!
How to perfectly combine the destination, altitude, speed and altitude, and enter the atmosphere in the right airspace is a test of a pilot's ability; of course, the computer will give the optimal trajectory, but there is no automatic driving here
Of course!
Because computers cannot control the use of mental power by the human brain! The whole process is manual, which is the characteristic of space odyssey. After humans entered space, they finally squeezed out the omnipotent brain. It is conceivable that as long as the source of power in space
It is provided by the power of the human spirit, and computers can never get involved!
Bei Haiyang could clearly feel that Tristan was much more nervous when landing than when taking off! The reason for the nervousness was that if he entered the atmosphere too fast, the plane would turn into a falling meteor!
There is a heat-proof shell on the outside of the modified fuselage, but the heat insulation of this shell is limited and cannot withstand the friction with the air at high speeds; it cannot be as thick as the space shuttle, otherwise, it will be
It cannot hold a few people, and it is not for commercial use but for scientific research use.
Tristan carefully controlled the speed of the plane. When it returned to an altitude of 50 kilometers, the speed had dropped below 1 kilometers per second, which is three times the speed of sound. Fighters can withstand such speeds, but passenger planes still can't. He
Need to keep going down!
But if it continues to descend, how to maintain the aircraft's attitude is a big problem, because the air begins to thicken again below 50 kilometers, and the wing rudder effect begins to take effect. It is no longer like in space, what direction do you give the aircraft force?
Just fly wherever you want. In the atmosphere, what determines the attitude of the aircraft is not the power, but the wing rudder surface!
The plane continued to descend. Tristan's focus was on the attitude of the plane. He had already used all the planetary energy he had mobilized from his mental power in this regard. There was no need to consider the speed. He could only fall faster and faster. He also
You have to brake the car from time to time!
When the plane passed through the ozone layer, the speed was already lower than the speed of sound. Tristan simply stopped the mental control, started it in the air, and the four engines began to work!
This is the most dangerous process! Bei Haiyang noticed that the pilot did not use hybrid power during the descent, but directly switched to engine power mentally!
This kind of operation is relatively simple and safe, but the aircraft's descent path is relatively steep; this is a matter of personal style, and there are no mature procedures to refer to. The pros and cons of various descent methods can only be slowly tested over time!
When the plane dropped below 20 kilometers, the most dangerous stage was finally passed. Bei Haiyang finally understood why there were so few space pilots and why it was so difficult to train them!
Any mistake in any link will make the landing fail!
To be honest, this is really a gamble with your life! I don’t know how many people dare to spend a lot of money to make such a joke with their lives?
Space planes are completely different from spaceships and much more dangerous!
