Chapter Four Hundred and Thirty-Five - One Step to the Sky
It will still take ten years for the actual spacecraft of the astronauts selected by this class to be completed, which is enough time for them to accumulate all their experience.
Huge and complex spacecraft cannot be manufactured like an industrial production line. They are destined to rely on a little effort, slowly and meticulously, and even require manual operations to complete. Even so, the scrap rate of parts is still high.
amazing.
"No. 2, check the driving system and compare parameters. I need to be able to connect to the manual at any time."
"Comparison completed", do you really need to do it manually? Didn't Engineer Chen say during class that the takeoff process is automatically preset by the program?"
"in case",
Rather than leaving your life in the hands of others, it is better to believe in yourself. Lin Mo firmly believes in this principle.
"Okay! Everyone starts to take their places, get ready, take one minute to adjust your breathing, exhale~~~breathe~~~exhale~~~breathe~~~"
The mentality before taking off is extremely important. Check, check, and re-check, and be more careful and more careful. The more preparation you have before entering outer space, the more confident you will be. As a reserve astronaut who is about to become a reserve astronaut, the calmer your mind will be at this time, the easier it will be to find the space.
question.
Even a slight risk may cause the sacrifice of astronauts. Before ignition, astronauts have a veto power to abort the ignition process.
No one can play with human life.
This breathing method is a small skill that Lin Mo has passed on to others. I am afraid that no one can master the secret of relaxation and calmness better than a warrior.
After calming down, everyone began to check all systems and functional modules again. It was not until before takeoff that Fenzhong stopped the inspection work and waited for launch.
With the sound of ignition, the simulator emits huge noises and vibrations. Hundreds of sound effect units of various powers simulate completely real sound effects. The strong vibrations are just like the real thing.
The images on the large LCD screen array outside the cabin could be seen in front of the cabin. With a violent tremor, the launcher quickly disappeared from the screen, and only a large expanse of blue sky filled the entire screen.
The simulation picture captured by the tail camera after feedback shows the strong driving force brought by the flames and smoke ejected by the launch vehicle and strap-on auxiliary rocket, sending the space hero to the sky, and the ground is getting further and further away.
Objects on the ground are getting smaller and smaller.
The gravity of the earth is always unwilling to allow any object to easily escape its own gravitational circle. A fighter jet can easily rise into the sky and fly freely, but it does not mean that it can escape from the atmosphere. This does not mean that it can fly upward indefinitely.
It can be done, but it requires powerful and powerful force.
Lin Mo and the others have already felt the overload transmitted from their space suits. This is completely different from the overload encountered by fighter pilots. The powerful and violent pressure covers almost every part of their bodies, even their hair.
, let alone move your fingers.
The seats in the cockpit are completely embedded into the astronauts and are very comfortable and soft, which can further offset the overload force and allow the astronauts to have enough physical strength to enter outer space.
The amount of g during overload training exceeds the actual situation, so as to achieve greater overload tolerance. Redundancy is necessary for the mysterious and unpredictable outer space environment.
If it were an ordinary civilian, he probably wouldn't be able to hold on for even a minute.
It is not easy to live in space. Those who are selected as astronauts must continue to receive higher-intensity training to truly adapt to space flight.
In the process of breaking away from the earth, it did not fly away from the earth in a straight line under the influence of the earth's gravity, but flew in a parabola, with a maximum orbiting speed of 7.9 kilometers per second (equivalent to 23 times the speed of sound), also known as the first
cosmic speed.
Such a powerful propulsion force can make the spacecraft gradually approach the first cosmic speed, truly drag it away from the earth's gravity range and enter outer space.
The speed of the spacecraft will become faster and faster. Through multi-stage ignition and fire, it will gradually reach the first cosmic speed. However, it will not be achieved all at once. In addition to considering the endurance of the astronauts and equipment, because in the ionosphere, including
In the near-earth atmosphere, due to the "thermal barrier" effect, when the speed of sound exceeds 6 times, the temperature accumulated at the top of the aircraft will exceed 1480 degrees Celsius, and can even exceed the temperature of the ionosphere.
If we forcibly reach a speed of more than 10 times the speed of sound below the ionosphere, I am afraid that it will turn into fly ash immediately. No matter what kind of high-wēn-resistant material is used, the temperature generated by this speed can even make stars burn.
Almost exhausted, let alone human spacecraft.
The distance when a launch vehicle carrying a spacecraft actually enters the high-speed stage is in the exosphere between 500 kilometers and 1,000 kilometers above the earth's surface.
Conventional surface-to-air missiles and air-to-air missiles are simply weak compared to space shuttle launches.
ào, there is no comparison at all, that is, the strategic-level intercontinental missile can still compete, and the others cannot even catch up.
This powerful speed and peak overload pressure, for
For astronauts, it is definitely a big burden.
Because the air is extremely thin and the center of the earth is out of reach, it is easier for spacecraft to reach astonishing high speeds.
As for the weightless outer space environment, there is no gravity, no resistance, and no friction. Even a fart travels at supersonic speed. If you throw something out casually, the range will definitely be farther than a missile, or even a missile.
Civilians can destroy any of mankind's outer space creations with their bare hands.
Satellites, space stations, space shuttles, and aerial and space fighter jets were all knocked down with one brick.
In this special environment, speed has become the number one fatal factor.
There was a strong shock that seemed to be about to disintegrate for 10 minutes, and then with a sudden light, the color of the sky displayed on the screen changed from light blue to sky blue, sky blue to dark blue, and the endless black starry sky was faintly displayed in the far distance.
"Now we are ready to enter the synchronous orbit. The main engine has been ignited!" The voice of the co-pilot Wang Xuejun kept coming to Lin Mo's ears.
, the combination of No. 2 and No. 2, the training center wants to see how the two best pilots will perform when paired together.
The voices of Lai Yaowu, the old number in charge of navigation, and Meng Yinan, the old number in charge of communications, are in contact with the analog communication nodes on the ground, and they are constantly talking to each other.
All booster main rockets and bundles
The ǎng-type auxiliary rockets were dragged away from the large layer one after another. At this time, the "Penglai" had begun its final sprint, and the territory below should be the United States.
Haha, if it was a real flight, it would have been locked by multiple land-based super-powerful laser cannons, and the same would be true for American spacecraft flying over Chinese territory.
In recent years, the military satellites launched by the Americans have often been blinded by the Chinese. Even the Russians have done this small trick, who makes you see things you shouldn't see.
If space military reconnaissance satellites can conquer the world, then there is no need for the old and American "Aurora" to come out to make soy sauce. At seven times the speed of sound, how can it be easy for me?
"Well, everything is normal. Switch to manual operation." Lin Mo's precise operation was highly praised by the training center. His driving skills are well-deserved. No one can beat him. Even Wang Xuejun had to do this. Admit it, this number's flying skills are indeed "a little bit" better than mine.
An experienced driver is even more reliable than a program. After all, when dealing with unexpected situations, the human brain is much stronger than a computer program on the board.
In the four days, except for the first step of entering orbit, then approaching the space station for docking, and returning, the main time was spent on space research and experiments.
The country spends huge sums of money and exerts so much effort to send them into space, not for tourism, but for space scientific research. Under the influence of weightlessness, vacuum environment, and cosmic rays, many biological species and substances will undergo wonderful changes. The change.
Some seeds will mutate, becoming stronger and better.
Without the effect of gravity, metal smelting will undergo very wonderful changes. For example, the tungsten-aluminum alloy that cannot be smelted on earth will either have vaporized in advance or become layers of aluminum and tungsten after cooling. , there is no way to fuse them together.
In the weightless environment of space, tungsten and aluminum will no longer have weight. Tungsten will be uniformly dissolved in the aluminum melt, and a sponge-like tungsten-aluminum alloy with pores can be obtained. This is a kind of alloy that can be widely used in aerospace and communications. Superconductors in high-tech fields.
This type of smelting, called space smelting, can achieve zero-contact pollution without spiral levitation. It uses electromagnetic coils to create electromagnetic induction to form eddy heating, and the fused materials are evenly combined together. It can achieve results that cannot be done on earth. We have obtained high-purity fusion materials, such as high-performance semiconductor gallium arsenide materials, barium copper oxide superconducting materials, as well as high-permeability magnetic optical glass, high-purity optical fibers, giant single crystals, high-roundness ball bearings and other special alloys.
No wonder there is another world in space. Rare extraterrestrial metals such as Split ore, which will trigger a war between the strong, and Lonsdale Stone, which makes humans in this world crazy, all prove that outer space is definitely an unprecedented place. Super big treasure zàng.
Coincidences born in complex and unknown environments may be able to create miracles.
As humans set foot in space, a new discipline, space smelting, emerged.
Dragon God, if Lin Mo's giant gold dragon knew this, I don't know if he would go crazy because of it.
This is just alloy smelting technology, there are also other national strategic research in biology, astronomy and other aspects.
Perhaps this word is the most appropriate word to describe the aerospace industry. Mastering advanced space technology will not only increase the country's scientific and technological strength and industrial foundation, but also improve the people's livelihood.
PS rewards and monthly tickets should also go to the sky. (To be continued)
