Airport Meow

Chapter 444 Roaming 2
The first voyage of the Space Consortium, the world's media are all building up momentum; but this time the real space roaming, there is very little public opinion.

Because this is not a stage for ordinary people. Ordinary people can spend money to enjoy the weightless environment of low-Earth orbit for several hours, but they can’t endure the torture of weightlessness for nearly ten days. This is originally the mission of well-trained astronauts. It has now been replaced by new human superpowers.

Five days later, a 959 with a very ordinary appearance took off from the ground at Narita Airport. From its appearance, it is almost impossible to tell that it is special. Instead, people pay more attention to the RB-753 and RB-755 that have frequently appeared in the headlines of the media recently. Pay attention to them Everything, including two island country pilots in their prime.

Bei Haiyang has been forgotten intentionally or unintentionally. This is the selfishness of the nation. They care more about their children.

Only the hull number of this plane still vaguely reveals its difference, Orient Express 01.

In the cockpit, there was only one pilot, Bei Haiyang.

After several months of space flight, people found that for space voyages, two pilots are not necessary. It is different from traditional civil aviation that requires the cooperation of two people to check each other's doubts and make up for each other. The uniqueness of spiritual power makes the whole flight process It's all the captain's discretion, and it's hard for the co-pilot to have a chance to make suggestions.

Because there are no rules and regulations for mental manipulation, since there are no unified rules, how can they cooperate?

Moreover, ordinary space routes are also very short of people now, so the single-pilot strategy was simply implemented; the existence of two pilots also has a substitute when one of them becomes unwell, but for them, new human superpowers, The enhancement of life makes the body controllable, and there will no longer be sudden diseases affecting driving.

Bei Haiyang likes this way very much, and he can do whatever he wants.

When Orient Express 01 came to low-Earth orbit, he basically had to rely on himself for future voyages, and space traffic control would not impose too many restrictions on him, including how to fly to the moon.

"East Pacific Aviation Control, this is Orient Express 01. I have entered the low-Earth orbit. It is expected to change orbit within half an hour and enter the Earth-Moon transfer orbit in due course!"

East China Sea Space Navigation Control, "Okay, the orbit change conditions are up to you, I wish you good luck."

The traditional moon landing flight is a twist and turn!It is composed of orbit segment orbiting the earth (also known as phase modulation orbit segment), earth-moon transfer orbit segment and orbit segment orbiting the moon.

The reason why it is so troublesome is actually because of the lack of power, and it has to rely on gravity to change orbit to achieve the goal of the near month;
Of course, the spacecraft can fly directly from the earth to the moon, and it is not difficult to be honest, but the premise is that there must be a deceleration before landing-no one would like to send a mushroom cloud or fireball when landing.

The time can be the traditional 3 or 5 days, but it can also be shorter. The shorter the flight time, the greater the energy required, and the greater the flight speed of the satellite when it is at perigee. When it reaches the perimoon point of the predetermined orbit of the moon, it will brake The greater the force, in other words, the greater the force required by the car when braking, the greater the risk.

In order for the aircraft to safely enter the orbit around the moon, 5 days is the orbit with the minimum energy.In the traditional sense, you can carry the least fuel, the smallest load, and the lowest accident rate.

If you want to land on the surface of the moon lightly, it means that the relative speed of the spacecraft when it reaches the surface of the moon is 0.

A feasible solution is to reverse the engine to slow down when it is about to reach the moon. For the audience, it is undoubtedly very handsome that the rocket roars away, and then makes a beautiful turn and stops suddenly.

However, the aesthetics of the vast majority of aerospace engineers is different from that of the general public. Turning around and stopping abruptly seems to them a stupid waste of propellant, and a precise "throw" is more in line with their aesthetics—— "Throw" the spacecraft, use the gravity of the earth to gradually decelerate, and when it reaches the moon, the speed will be decelerated to 0.

This is the standard operation of the traditional near-moon landing. When the collision of civilizations comes and the transfer of planetary energy by spiritual power becomes a reality, handsome movements become possible, because the pilot no longer has to worry about fuel propellants.

Combat spacecraft can easily do this, but space airliners are almost meaningless. The consensus is that their aerospace airliners neither need to use traditional winding methods to approach the moon, nor can they approach the moon like combat spacecraft. The best way to speed up the brutal speed is to go around the earth to speed up, find the time window to directly enter the earth-moon orbit, break away from the earth's gravity at the farthest end, and change orbit again to enter the moon orbit.

It is a compromise, and it is more suitable for the capabilities of aerospace aircraft.

Bei Haiyang felt that if he exerted all his spiritual strength, he could control even this huge space passenger plane to fly directly to the moon. It would be good to see if Sister Chang'e chased it hard, but it would be possible to do so. It's a bit shocking, but it's not necessary, he is not in a hurry, and sister Chang'e is not waiting for him on the moon to drink flower wine.

Therefore, it is good to go around the ground honestly and continue to change orbits.

In traditional aerospace, it takes at least three turns around the earth to reach the earth-moon orbit, but since he doesn't need to think too much about fuel, one turn is enough.

In fact, his current orbit is not fixed at all, but is constantly changing, accelerating towards the far orbit!
If an object moves around another object only under the action of gravity, according to Kepler's law, its trajectory must be an ellipse, so before the engine stops working and the spacecraft approaches the moon, its orbit will be a perigee near the earth, The apogee is an elliptical orbit 38W kilometers away from the earth, which is the earth-moon transfer orbit.

This can be heard from his constant reports to the ground,

"East Pacific Aviation Control, this is Orient Express 01. My current orbit is 3 kilometers near the ground and 5 kilometers away..."

"Dongtai Aviation Control, I am now 4 kilometers away from the ground and 5 kilometers away..."

"Entering the Van Allen radiation belts, the plane is fine."

"5 kilometers near the earth, 38 kilometers far away, goodbye to the earth..."

Once in orbit, it cannot be accelerated casually!If the acceleration is too fast, the car will not be able to stop when it is close to the moon, and it will rush out of the gravitational field of the moon, and it will fly to nowhere.

Therefore, it should be a state of controllable acceleration. He has to consider the problem of deceleration after flying half of the voyage and 20 kilometers away from the earth.

At his current average speed of 10 km/s, the time to reach the near-month orbit is between 10 and 15 hours. The specifics depend on how he slows down, whether he presses on the brakes suddenly, or pulls the accelerator and brakes?
The moon is much smaller than the earth, with 80/1 of the weight and 6/1 of the gravitational force. That is to say, when approaching the moon, he must reduce his speed to 2.4 km/s or below to be successfully captured by the moon.

Doesn't seem too difficult?
