Chapter 8 wing

Since the middle of the 21st century, small private jets have become the main means of transportation for people on earth to travel.Cities are getting wider, buildings are getting bigger and bigger, ground transportation is getting more and more overwhelming, and the sky is becoming more and more occupied by small cars with wings.On Earth, flying is a complicated business.For children, it is a dream and stimulation, for teenagers, it is a means of chasing girls, for adults, it is a status symbol, and for the elderly, it is a means of transportation that they complain about but have to rely on.For sociologists, it is the birth of a new organizational form, for politicians, it is airspace disputes, for environmentalists, it is the chief culprit of atmospheric destruction, and for businessmen, it is a golden medicine to save economic recession.For all, it is a symbol of a new era.

Middle school students go to school, college students take risks, celebrities go on vacation.Everyone has different appetites, and the airplane becomes a complicated thing.For high speed, a new type of solid fuel is needed; for stability, a wingtip stall balancer is needed; for reaching different altitudes, a combustion ratio controller is needed; for not colliding with other aircraft, a precision global navigator is needed; for adapting to various airflows, An intelligent detection controller is needed; in order to avoid mistakes caused by human fatigue, a fully automatic pilot needs to be integrated; for remote communication and electronic conferences, high-definition display screens and signal receivers are needed; in order to prevent attacks, automatic navigation shells are needed; in order to survive, Advertisements are needed; ejection umbrellas are needed for immortality; soft reclining seats are needed for sex.Airplanes have become all kinds of strange shapes and materials.

When simplicity becomes complex, simplicity is forgotten.Just like children know that they can live by eating and sleeping, but adults say that people need a lot of things to live.It takes a lot of patience to go from complex to simple. "One can live only by eating," Mira said. Sorin lowered his head, and the electronic paper with messy pictures was spread out in front of him: "But we have nothing to lose." On the electronic paper, the names of various components are marked in crooked handwriting, and big forks are drawn on some components.The three boys gathered around the thin paper, discussing with their heads down, and Luo Ying sat on the iron shelf next to them.The boys want to carry out a comprehensive transformation of the small Mars aircraft, remove the functions of mining escort, combat and transportation, and take the height and speed as the standard to be able to fly, using the smallest facilities to achieve the most streamlined purpose.

This is the seventh day after the preliminary round of the creative contest.After passing the preliminary round, the team was formally established, and the experimental plan could be included in the agenda.Anka told her partner about her aircraft transformation plan, and received an unexpectedly positive response. Luo Ying's idea of ​​going to the valley to find the relics of the past also received a lot of support. Several people eagerly wanted to go with her. Long Ge Proposed to rent a mining ship, Chenia took the initiative to organize and convene, and Sorin began to direct the secret operation while directing the drama.Luo Ying can understand such a reaction. After all, in the days of being trapped in the bottom of the glass box and struggling with the summary report every day, an adventure trip to pursue the past has incomparable exciting power.Several core members began to gather every day to discuss practical plans, and Luo Ying's own pursuit gradually expanded into a consideration of history and a desire for the sky.

"I think our way of thinking is reversed." Anka leaned against a pillar beside her and said in a low voice. "What do you mean?" Thorin looked up at him. "We've been subtracting from the plane, so everything is necessary, but we can actually start from nothing and add only the most necessary things," Anka said. "Starting from nothing?" Thorin frowned. "It's not nothing, it starts from the air." Luo Ying sat on the iron frame opposite the three of them, with her feet shaking slightly without touching the ground.The three boys had been discussing intently all night.

Their studio is in a corner of the rehearsal warehouse. The lonely small room is like a large signal box. The iron frame surrounding the hall passes in front of them, with sharp edges and corners, leaving only a small triangle.The night has come, no one visits, the hall is empty and dark, only this corner is lit.The boys moved a few boxes, sat casually, wrote and drew, the playback box was projected on the wall, and various airplane photos were played one by one. Anka leaned against the pillar, with one foot crossed in front of the other, looked at Thorin and said, "After all, we don't have any missions, just want to fly to the cliff without falling. So we can just give up In traditional aircraft, only the wings are left, the fuselage is simplified, and the engine can be omitted. This can minimize the load."

Sorin was surprised: "Engine? How can it be unnecessary? Even if solar energy is used as energy source, the jet of the engine can't be ignored, right? If there is no jet, how can it be used for thrust? Even if the wings can vibrate, the speed of level flight is still required." Anka shook his head and said, "The speed of level flight is what the plane needs for headwind lift. If we don't care about the heading, we can fly along the wind, like some insects." Mira asked: "Tail wind? Haven't you calculated it? The lift is not enough." Anka said: "The total lift is positively related to the area of ​​the wing. We can make the wings as large as possible. The lift of the thin atmosphere is small, but the destructive force per unit area is correspondingly small. I calculated that the wings can be made bigger than those on the earth." several times larger."

Mira was a little skeptical: "But can the wing roots hold up? The bending moment will be huge, right?" Anka shrugged and said, "I don't know. I just thought about it. I can't say if it will work." Sorin nodded slightly, and said to Mira: "I think it's worth it. It should be possible to find the right moment point for the support of the wings. The most important thing is the lift-to-drag ratio. You have to find the right shape of the wing, and the right wing. The wind. I think it is still feasible, although the air density here is low, but the wind is very strong in many places."

Luo Ying didn't speak all the time, holding her small drawing board and drawing casually.Thorin's eyes were a little closer together, but they were very bright.Meera has brown skin, a round face and matted hair.Anka couldn't stand up straight and didn't wear his shoes properly, but he looked very slender leaning against the pillar.She didn't quite understand their discussion, but she heard Anka's words: the plane was nothing but a dance of material and wind.This made her suddenly understand one thing: talk about the air before talking about flying, talk about the surroundings before talking about action.

The night was quiet, Luo Ying looked at the boys and the moon outside the dome.Like her, they are used to walking in the sky on earth.She felt reassured looking at them, and although she didn't have a clue yet, she always felt that as long as they wanted to do anything, they could do it.She didn't know why she had such beliefs, maybe it was because she was used to drifting with them, maybe it was because she liked to see the fire in their eyes when they thought. The boys began a lively discussion about the conditions and equipment necessary to fly with the wind.It sounds like there are all kinds of unrealistic and insurmountable problems, but they carefully considered each place and place, and even cleared most of the obstacles.There are only a few small places left, like stubborn illnesses and bottlenecks, like stuck in the throat.

"Luo Ying, do you still remember the specific description of the local terrain in the file?" Suo Lin suddenly raised his head and asked Luo Ying, the three of them stopped and looked at her, obviously they had encountered disagreements and needed reliable outside information. "Remember," Luo Ying looked at them, "it's just that I didn't talk about it." "What did you say?" "It is said that it is a turning rock, straight up and down into the sky, and the mountain wall will blow off a lot of sand and stone in strong winds." "Will it be very windy?" "It will be quite large." "But that's what it was like during the storm?" "yes." "What about normal times? How is the daily wind?" "It's not written in the file." Luo Ying hesitated for a moment, "But it seems that there are many wind tunnels on the mountain wall, and there are also wind-eroded ravines." The three boys looked at each other, and Sorin nodded to Anka. A few words were written on the paper. "Do you know its exact location and route?" Anka looked up after writing, and asked gently. "I don't know. But it must not be too far from the camp, because I remember a sentence at that time very clearly, saying that if a rescue ship was sent at that time, it would be able to go there in half an hour." "Can the rescue ship go all the way?" "can." "Then our boat can sail there no problem." Anka said to Mira. Mira nodded. It could be seen that this was a big question of his. He was relieved when he heard the answer. "Then what kind of plane should we build?" Mira thought for a while and asked, "Let's just drive the mine ship there." Luo Ying shook her head and said, "Although the valley I'm looking for is on the ground, the other ruins are all on the rocks." "On a rock?" "Yes." Luo Ying affirmed, "Aren't the previous camps all on the rocks, I really want to see them too." "Really?" Mira looked very surprised, "Why didn't I know?" "You don't know?" Luo Ying was also a little surprised, "I thought everyone knew." "I don't know." Mira turned to look at the other two, "What about you?" "I don't know either," Anka said. "I seem to have heard a little bit, but not much." Sorin frowned slightly, and said, "Now that I think about it, it's really strange. We didn't talk about that period of history in detail in class, but we talked a lot about wars. , but I really don’t have much memory of the time before the war.” "...It seems so." Luo Ying admitted after thinking about it. "Then how do you know?" Mira asked. "I also forgot... Maybe my parents told me when I was a child. I can't tell, but I have always remembered it." "Can you tell me about the specific terrain?" Anka asked. "I know it's a valley, and people live on the rock walls. Others... I don't have much memory." "Can you look it up or ask?" Just as Luo Ying wanted to say that her parents had been dead for so long, and she didn't know who else to ask, she suddenly thought of Rui Ni.She felt that he must know. He has been writing history for so long, and the information in his hand should be the most detailed.She nodded and promised that there should be no problem. Anka nodded, picked up the electronic paper on the floor, wrote a few words, scanned it from the beginning to the end, and concluded: "Today is almost here. We have solved a lot of problems just now, and now we have to go back and forth." There are two most critical things, one is the terrain, and the other is the control of the wings, and it is impossible to have an answer right now, we will all go back and check, and send a letter to contact us if we have any results." "What wing control?" Luo Ying couldn't help asking. "One of the most core technical problems." Anka explained, "Don't we want to make the wings bigger, so that although the airflow can be used in this way, it also brings a serious problem: the movement of the wings will be very difficult to control. The actual Turbulent gas is unpredictable, so the program is difficult to design, and even if it is designed, it may not be applicable. The airframe is simplified, and the program control is especially difficult. But it must be controlled, and the wings cannot be used to talk about it. " "Is that so..." Luo Ying murmured. She doesn't know programming, so she doesn't know what the specific difficulties are, but she can hear the seriousness of the problem from Anka's tone.All the existing designs are the most beneficial essence left by people in repeated revisions, and any revision will face various additional troubles.She's not an engineer, but she understands it.She looked at the boys, their faces serious with questions, handsome with seriousness.They can see the problem, but it makes their faces shine.She walked beside them and walked out of the empty warehouse shrouded in darkness, suddenly there was a sense of solidity and warmth in her heart that she hadn't felt in many days. ※※※ Luo Ying and Rennie were in the insect laboratory. This was a request she made to him. She said that she wanted to know the flight principle of insects, and he readily agreed to take her to the insect experiment garden where he used to go to school. Rainey spent three years here as a young man, learning about biomotor receptors and pressure sensing.On Mars, many mechanical vehicles imitate the structure of crawling insects, mining with slender and flexible limbs, and walking like flying on the rough soil full of gravel.Here he studies the limb movement of insects, transforms them into electrical machinery, and applies them to engineering design. There is a large greenhouse in the laboratory, which is planted with many kinds of precious and rare flowers and trees, paved into a man-made jungle with scattered heights, where bees, dragonflies, praying mantises, spiders and various beetles are raised.As soon as Luo Ying stepped in, a dragonfly landed on top of her head. She yelled loudly, and the dragonfly flew away trembling.She was stunned, standing blankly, her thoughts wandering, completely shocked by everything in front of her eyes.She has almost never seen such a scene, every flower has golden stamens spreading out, bugs hiding in every corner jump out from time to time, every pair of wings flaps a bright temptation.Eyes are lush, butterflies fly up and down, and big flowers bloom like girls' skirts.Not only has she never seen all this on Mars, she has never seen it on Earth.She has seen flower shops and grasslands on the earth, but she has never seen such a rich and free animal garden. "It's beautiful." She sighed softly. "It's beautiful," Rainey said. "That's why I chose this major." "Are these bred on Mars?" "Yes. In the early days, only ten pairs of each species were introduced from the earth, and all the rest were bred here." They stood in the middle of a bunch of flowers, Rui Ni gently picked up a butterfly from a flower, and put it in Luo Ying's hand, Luo Ying looked at it carefully, the butterfly lay quietly, its slender legs trembled quickly, she thought Touch it, reach out and it will fly. "Dr. Rainey," she asked, looking up, "how can insects fly?" Rui Ni picked up a little bee next to him, turned it upside down, showed Luo Ying its chest, and said, "Did you see the wings vibrating? This is the most basic motivation. It's just that different insects have different ways, bees It relies on the twisting of the wings to change the angle of the air trapped between the wings, while the dragonfly relies on the flapping of the two pairs of wings to create small eddies." "Is it the same as a bird?" "It's not quite the same," Rainey said. "A bird's wing doesn't vibrate, and an insect's wing flaps very little." "How to control the wings of insects?" "It's basically twisted by wing root muscles, and their wings are very thin." Luo Ying lowered her head.The little bee struggled hopelessly in Renee's hands, its belly bent to its chest, its thin legs kicking back and forth, and its armor-like mouth kept shaking.Reni let go, and it staggered into the air.He stretched out his hand again, and a dragonfly flew over and landed on his hand. Renee looked at it and smiled, "Let's say something off topic. I think people rely too much on numerical simulations now. They give everything to the computer for calculation, but rarely observe it. This is exactly the opposite of ancient times." Time flowed silently, and an afternoon passed quickly.At dusk, Luo Ying pondered for a moment in her heart. "Dr. Rainey," she asked abruptly, "did there be a time when people lived in the valley?" "Huh?" Reni was stunned for a moment, but still replied calmly, "Yes. To be exact, it's a huge crater." "When did that happen?" "A hundred years ago." "Why do we seldom hear it?" "Because the evaluation of it is complicated." "Why is it complicated? What kind of place is that?" Reni was silent for a moment before answering.His words were slow, like drawing a virtual ancient painting in the air: "At that time, people didn't have glass houses. Except for the iron camps directly transformed from ships, most of them lived in caves and underground bunkers. Although the mountains The rock is cold and lacks light, but it can block cosmic rays quite powerfully. For people, survival and safety are always the first. As you can imagine, the room at that time was quite simple and rough, with a small hole connecting the outside world. The yellow walls are only rough polished, heated by an electric stove, and the lights are turned on during the day. Even so, that kind of house is not easy to build. All construction work must be done on the rocks, and many mechanical vehicles are difficult to climb, so A lot of work has to be done by hand, which is quite laborious. Once it is destroyed, it will take a long time to dig it up again. Most of the living materials are waiting for the earth to supply." "Do Earthlings live with Martians?" Rennie looked back at her and smiled, "There were no Martians at that time, and everyone was from Earth." Luo Ying's heart moved slightly, she chewed on the meaning of this sentence, like an ancient riddle. "Where is that valley?" "In the middle of the great cliff, not far south of the equator." "Are there any relics of that year?" "There should be more, as long as they are not damaged by the war, they should still be there." "Can we still go there and see?" "I'm afraid it's hard. People don't go anymore." "Can't you go by yourself?" "I'm afraid it's even more difficult." "Doctor Rainey," Luo Ying paused, quietly squeezed the brass apple that was always on his body, and asked cautiously, "Why did you fight the war back then?" Renee looked into her eyes and asked her back, "I think you know the cause of the war, right?" "Yes." Luo Ying nodded, "but what I want to ask is the purpose. The cause is the cause, and the purpose is the purpose." Renee nodded to express his understanding: "The main purpose is a brand new social formation." "Like our current city?" "It can be said that it is. But it is only the prototype and core. The current city operation is slowly developed after thirty years of war." "What was the original core like?" "Database. The core of everything is the database. Develop a city that runs on the database. It is not used to calculate the city's operation, but just to store. Store the discoveries of everyone in the city, every new exploration, and share freely . to protect freedom of thought for all.” "But why do you have to be independent? Can't you do such a thing in the original camp?" "Unlikely. Because this involves a change in the overall economy. In other words, such a city requires full disclosure of all spiritual exploration and no participation in the economy, that is, a complete separation of material production and spiritual production. For the first time in history, there is complete clarity in the domain of "That is to say, the product of the spirit does not participate in the transaction?" "Yes. That's exactly what the people at the time were proposing." "Is this good or bad?" "I'm afraid there is no answer." Renee said, turning his eyes to the twilight sky. "At least in the hearts of the group of people who started this operation spontaneously at the beginning, this is a belief. It is a belief, and it is difficult to tell whether it is good or not. measure." "What kind of life is that..." Luo Ying whispered to herself. Rainey didn't make a right or wrong evaluation, but he succinctly talked about some historical choices, talking about the young life of Luo Ying's grandfather and his friends.He didn't go into details, because he felt that the flow of historical events was far less touching than the fragments of people's gestures. Rainey had read a lot of literature before the end of the war, and was inevitably moved by the cloud-like enthusiasm in it.It was a vivid era with a bit of unrealism.Utopia in the sand.Dig a clear spring in the dry world.Many jobs in that era did not need to be motivated to make the sand bloom. This imagination itself inspired many people. In the early days of the war, the rebel army was still stationed in the valley, which was just far away from the valley of the earth garrison. The only difference was that the rebel army was closer to the edge of the cliff and closer to the great plain.This is because although half of the food supplies at that time came from the contention with the Earth Garrison for transporting supplies to the Earth, the rebel army still needed to open up planting and breeding gardens.At that time, science and technology were advancing by leaps and bounds. Perhaps there was no era in history that brought together so many intelligent minds under such pressure.The rebels themselves were scientists, who were dissatisfied with the various intellectual barriers between the original camps and broke through the shackles.Those barriers come from politics and business, and have nothing to do with them. They only know that on Mars, where the living conditions are so harsh, if they cannot freely communicate with each other's discoveries, if the gains from exploration cannot be shared, then everyone will be unable to move forward.They built information platforms just for development, at that time there was no art, no craft decoration, no political voting and everything after that. War breeds a generation born of war.They were born here, lived here, and many died here.Hans, Galman, Langning and Garcia are all children of war.They've all been pilots, but not just pilots.They grew up in the era when the situation was the most difficult and people's beliefs were most shaken, and they are the inheritors of the beliefs. The latter part of the war was the period when Hans and his companions took to the stage.Hans was a robust young man who flew with his new wife and became a pilot training instructor at the age of twenty-two.His father was still alive then, entering his prime as Mars Marshal, and the haggardness of radiation sickness had not affected the old man's vigor.At that time, Galman was beginning to be high-spirited, roaring like a blond lion, and it was his architectural design that finally made the rebels determined to come out of the valley.The personable Garcia was actively speaking around. At that time, he had already shown the potential of a diplomat many years later, using sharp words to make the ideal of the database live in the crowd.Lang Ning, full of poetry, published a series of articles in succession, transforming Habermas' communicative rationality into brilliant and passionate elaboration, extending to all aspects of urban construction. That was the age when all ideals were most abundant.Rainey knew that no matter what the reality was, people at that time had reached out and sought the sky so truly. ※※※ When leaving the insect laboratory, Luo Ying suddenly wanted to dance. She has not danced for many days, her heart is occupied by more concerned things, and her body has been in a state of recuperation.She thought she had bid farewell to dancing, no matter her legs, feet or mood.Today is the first time since she was injured, she has the desire to dance, to move her whole body, to jump up and spin into a fully engaged state of life.She couldn't tell what it was for, maybe it was because of the flying butterflies she saw, maybe it was because of the cliffs in the sky, maybe it was because of the history of breaking the shackles she heard, maybe it was because of flying.She stopped at the door of the insect laboratory, looked back at the wings fluttering in the green shade behind the glass door, and the impulse in her body that had been sleeping for a long time began to swim away again. She bid farewell to Reni, and came to the dance classroom where the lights were turned off. Without turning on the lights, she slowly stretched her hands and feet against the blue street lights of the city that had already been lit.Press your legs, stand in the basic foot position, and rotate continuously in front of the mirror.She stepped on the thick wooden floor, feeling very at ease in her heart.The floor is a faithful dance partner.It supported her, and she felt its touch with her toes. She danced, her thoughts following her body ups and downs. She knows that dance philosophy in the 22nd century is very complicated. People understand dance as the relationship between adults and space, and there are many contradictory trends. All kinds of symbols on people... But for her, she thought far less profound and complicated.For her, dance is not a relationship with the outside world, but a relationship with herself.She has thought about where the goal of dancing is many times, and the final conclusion is control.The project team asked her to learn to jump and develop human physical height, but she felt that accuracy was far more important than height.The most difficult thing is not to be higher, but to let the toes just reach a certain position, neither high nor low. She lightly kicked her legs to waist height, then retracted them, kicked them backwards, and stood still. After learning to dance, she realized how limited people's understanding of their own bodies is.People don't think about how to sit, how to stand, how to move and walk without falling.Those actions are actually very profound, but people rely on instinct and don't need to consciously control them at any time.How amazing it is, it's like the body itself has life.The body has much older memories, habits that the rational mind never even knew about. Suddenly, a light flashed in her heart. Her thoughts drifted back to the night before, to the high iron hall, to the middle of the boys' argument.At that time, all the efforts were missing a key link, just like a jigsaw puzzle lacking the eyes of the characters, everything is there, but the picture is not. Now she knew which piece was missing.It is the control of the wings. The control of wings may not require the brain, but only the instinct of the body.
