Airport Meow

Chapter 158
Bei Haiyang didn't know that there were so many people down there worrying about him!
It took a lot of effort to crash in from the atmosphere. It is not an easy task to keep a large rock weighing nearly [-] tons from evolving into a free fall!
As can be seen from the command center below, this is a process of gradually restoring the posture, and controlling the altitude and speed to the ideal state is the only thing he has to do.

There are many difficulties, his spirit has not been restored to the best state, the No. 9 spacecraft is dilapidated, and his pilot experience is limited... All these shortcomings make his whereabouts possible to fall at any time!
But there is also a piece of good news, that is, the closer he is to the earth, the stronger the planetary energy he can mobilize, which makes his forced landing a little bit more likely to succeed!

There is no need to reduce the speed anymore, the more and more viscous air is the best speed reduction medium, what he mainly does now is to control the flight attitude and firmly control the altitude in his own hands!
Flying a spaceship is completely different from flying an airplane, because he does not need to think about the messy parts on the airplane that control the attitude, flaps, ailerons, spoilers, speedbrakes, elevons, tail rudders, stabilizers, etc., these things It is so complicated that even the pilot has to rely on the flight control computer to control these components to maintain linkage, which is the pain that modern aviation has to say.

But the spacecraft completely discarded these things, because it is used to fly in space, so fluid dynamics are not considered at all, and there is no fluid in space!

The appearance of the spaceship is a large flat cone with only the hull and no wings!
Its attitude control is accomplished entirely by powerful power, twin main thrusters, and attitude adjustment boosters arranged on each ridge of the cone. There are six such boosters on the Huaguo spacecraft. .

Airplanes pay attention to the 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, and more emphasis is placed on the thrust-to-weight ratio of the whole machine.

If you want to measure the flight capability of an aircraft, the thrust-to-weight ratio of the whole aircraft is very important. The thrust-to-weight ratio of modern fighter jets can reach 1-1.25; the ratio of bombers is 0.25-0.50, and the value of civil aviation airliners 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 spaceship and the star!

For example, the human spaceship of earth civilization, where it can produce the largest thrust-to-weight ratio is the moment it starts on the ground!You can throw a [-]-ton spacecraft like throwing a stone, and then as it leaves the ground and the planet, the energy support it can get is also rapidly decreasing; when it flies out of the atmosphere, there will be an end-of-life Energy decay!
Therefore, the intelligent creatures of planetary civilizations have a cosmic detection range around the planets. If you fly far away, you will not get energy support. You have strong spiritual power but no home planet to absorb energy.

The same is true for star civilizations!Like the extraterritorial civilizations that the earth is encountering now, the reason why they never enter the earth's atmosphere may not be that they have to follow the laws of cosmic biological coexistence. The more important reason is that they have decayed to the extreme because they are too far away from the stars. The energy supply will be completely offset by the planetary force field due to entering the atmosphere!

If it really enters the atmosphere of the planet, not to mention sending out energy beams, it is difficult to maintain flight, it is just a big solid stone!Even those fossil-fueled traditional fighter jets can't compare, 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 balance of energy use!
Having said so much, the fundamental reason why Bei Haiyang can completely control his posture at an altitude of [-] meters is that the energy he can use now is greater than one if measured by the thrust-to-weight ratio, so he can fly normally!

If he wanted, he could just hover at an altitude of [-] meters, but he didn't want to do that.

At an altitude of 3 meters, the speed of 400 knots is the best control range of his mental power at the moment, he can maintain the flight, and he still has some spare energy to deal with accidents...

His current location has just entered the Pacific Ocean!
Everything seemed to be going smoothly, but now he immediately realized a problem: how to navigate?How to go home exactly?
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 descended to a position of [-] meters, it is no longer possible to observe the earth from such a height, but can only see white clouds, blue barking sea...

Which route is the most accurate, he does not know!
Even though he used to be an airliner pilot, the education he received from the moment he entered the industry was to fly everything according to the route of the flight control center, what altitude, what direction, and when he was about to arrive, he would naturally see the airport!

This kind of flight training did not teach him how to correct the course through the different islands in the Pacific Ocean below. In fact, from his height, those islands all look the same, only different in size...

There is no stop sign!Bei Haiyang lamented!
He knew that he was leaving the continent of South America, which was a basic judgment.There isn't even normal communication on the ship, because these things are useless in space!

No one will come to indicate his course, there is no such reason, and there is no such condition; and he will not take the initiative to speak up. He has already returned here, and it is very possible to return safely, so why expose himself?

You can only find a general direction. Fortunately, it is noon when it falls. If it is night, it will 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 eyes 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 as vigorous as a dragon in space; there were many reasons, but the most critical one was the inadaptability to air resistance, which was Factors that do not need to be considered in space are magnified to the maximum in the atmosphere!
No wonder every country has never thought about building an atmospheric fleet. The investment is too large and the effect is not good. It is better to let the traditional fighter fleet 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, to find a flight back home to follow, whether it is from Feihua country, island country, Great Cold or Wanwan, it is actually the same!
That's why he stayed at an altitude of [-] meters. As Ya, the busiest route between the two continents, the Pacific Ocean is very lively!
