Bei Haiyang didn't know that so many people below were worried about him!
It takes a lot of effort to crash into the atmosphere. It is not an easy task to keep a large rock weighing nearly a hundred tons from falling into free fall!
As you can see from the command center below, this is a process of gradually repairing the attitude. Controlling the height and speed under the ideal state is the only thing he has to do.
There are many difficulties. His spirit has never been restored to its best state. Spaceship No. 9 is in dilapidated condition. His piloting experience is limited... These many shortcomings make his whereabouts possible at any time!
But there is also good news, that is, the closer he is to the earth, the stronger the planetary energy he can mobilize, which gives him a chance of success in his forced landing!
There is no need to slow down anymore. The increasingly viscous air is the best medium for slowing down. What he mainly does now is to control the flight attitude and firmly control the altitude in his own hands!
Driving a spaceship is completely different from flying an airplane, because he doesn't need to think about the messy attitude control parts on the airplane, such as flaps, ailerons, spoilers, speed brakes, elevons, tail rudders, stabilizers, etc.
It is so complex that even pilots have to rely on flight control computers to control these components to maintain linkage, which is a pain in modern aviation.
But the spacecraft completely abandoned these things. Because it is used to fly in space, it does not consider fluid dynamics at all, and there is no fluid in space!
The appearance of the spacecraft is just a large flat cone, with only a hull and no wings!
Its attitude control is completely accomplished by powerful power, dual-engine main thrusters, and attitude adjustment boosters arranged on each edge of the cone. There are six such boosters on the Huaguo spacecraft.
.
Aircraft pay attention to thrust-to-weight ratio, which is the ratio of engine thrust to engine weight or aircraft weight. In civil aircraft, the thrust-to-weight ratio of the engine is less important than the thrust-to-weight ratio of the entire aircraft.
If you want to measure the flight capability of an aircraft, the thrust-to-weight ratio of the entire aircraft is very important. The thrust-to-weight ratio of a modern fighter can reach 1 to 1.25; the thrust to weight ratio of a bomber is 0.25 to 0.50, and the value of a commercial airliner will be even lower!
There is no upper limit to the thrust-to-weight ratio of the spacecraft! But it depends on the position between the spacecraft and the star!
For example, the spaceship of the human civilization on earth can produce the maximum thrust-to-weight ratio at the moment it starts on the ground! You can throw a hundred-ton spaceship like a stone, and then as it leaves the ground and the planet, it can gain
The energy support is also decreasing rapidly; after flying out of the atmosphere, there will be a terminal energy decay!
Therefore, the intelligent creatures of planetary civilization have their cosmic detection range around the planet. If you fly far away, they will not get energy support. They have strong mental power but no parent star to absorb energy.
The same is true for stellar civilizations! For example, the extraterrestrial civilizations that the earth encounters now, the reason why they never enter the earth's atmosphere may not be that they have to follow the coexistence laws of the universe. The more important reason is that they are originally due to their distance from stars.
The energy supply that is too far away and attenuates to the extreme will be completely offset by the planetary force field as it enters the atmosphere!
If it really enters the planet's atmosphere, let alone emitting energy beams, it will be difficult to maintain flight. It's just a big solid rock! It can't even compete with those traditional fighter jets powered by fossil fuels, so what's the point?
Therefore, they never come in and only reach a certain balance with human civilization in outer space!
In fact, it is a kind of balance in the use of energy!
Having said all that, the fundamental reason why Bei Haiyang can completely control his attitude at an altitude of 10,000 meters is that the energy he can use now, measured in terms of thrust-to-weight ratio, is already greater than one, so he can fly normally!
If he wanted to, he could just hover at an altitude of 10,000 meters, but he just didn't want to do that.
An altitude of 10,000 meters and a speed of 3,400 knots is the best control range of his mental power at the moment. He can maintain flight and still have some energy to deal with accidents...
His current location has just entered the Pacific Ocean!
Everything seemed to be going smoothly, but he immediately realized a problem: how to navigate? How to get home accurately?
In outer space, he can roughly determine his direction by observing the outline of the earth, but now that he has entered the atmosphere and dropped to a position of 10,000 meters, it is no longer possible to observe the earth from a full field of view at such a height, and he can only see white clouds and blue clouds.
The vast sea...
He doesn't know which route is the most accurate!
Even though he was once a passenger plane pilot, the education he received when he entered this industry is to fly according to the route of the flight control center, what altitude and what direction. When he is almost there, he will naturally see the airport!
This kind of flight training did not teach him how to correct his course through the different islands in the Pacific Ocean below. In fact, from his height, the islands all looked the same, differing only in size...
There is no stop sign! Bei Haiyang lamented!
He knew that he was leaving the continent of South America. This was a basic judgment. There was not even normal communication conditions on the spacecraft, because these things were not useful in space!
No one will come to indicate his course, there is no such motivation, and there is no such condition; and he will not take the initiative to speak, he is already back here, and it is highly possible to return safely, so why expose himself?
I can only find a general direction. Fortunately, it was noon when I fell. If it was dark, it would really become a ghost floating in the air with no sense of direction.
It's just that he doesn't know that he thinks he is a ghost, but his every move is under the watchful eye of many national forces, but no one comes to contact him.
During the operation, he felt that the movement of the spacecraft in the atmosphere was still relatively clumsy, far from being compared with the robustness of a dragon in space. There were many reasons, but the most critical one was the incompatibility with air resistance.
Factors that do not need to be considered in space are magnified to the maximum in the atmosphere!
No wonder various countries have never thought of establishing an intra-atmospheric fleet. The investment is too high and the effect is not good. It is better to let traditional fighter fleets maintain it.
To determine the course, the easiest way is to find a reference object, but he knows nothing about this sea area and has never flown the Pacific route, so this method is not suitable for him now.
Then, there is only one way left, find a flight back to China and follow it, whether it is from Feihua Country, Island Country, Dahan or Wanwan, it is actually the same!
This is the reason why he stayed at an altitude of 10,000 meters. As the busiest shipping route between Yaoshu and Mizhou, the sky above the Pacific Ocean is very lively!
