The wings of human flight
A lost elegy sounded.
Wandering lambs miss your dear mother outside. Wandering footsteps travel all over the world, without a home. The winter wind, carrying snowflakes, blows down my tears. Wandering lambs miss you outside, dear mother, wandering footsteps across the world, without a home. The winter wind blew down my tears with snowflakes. Walking and walking, walking and walking, how many years have passed. The grass in spring was sprouting. It was another spring and summer. He tossed and turned in the grasslands of Sun Tribe City, firing a shot here, firing a shot there, taking a roundabout route to save the country, hiding everywhere. A lost lamb, a mysterious life. ----- The lambs that had left home were wandering outside. They did not have good clothes, let alone good steamed buns. Surviving in the crevice, the bitter wine of life brewed by itself, a lamb that ran away from home. Tears of repentance flowed from her heart, and her tender face was filled with sorrow. The lambs from home. At night, she couldn't sleep and thought of her parents in the distance. Tears streamed down her face. Spring was already full of flowers, autumn leaves were yellow, and winter was already snowing. Please don't catch a cold. The moon is round, the moon is round. The moon is round and another year has passed. It's not that I don't care about this child. Life was really difficult. Children from home, lost lambs, stranded outside. The child who left home could not sleep at night. When he thought of his parents in the distance, tears streamed down his face. Spring is already blooming with flowers. autumn leaves turn yellow. It's snowing in winter ~~~~"Hehe, this natural creature is so awesome.”"Yes, carrier pigeons are experts in mastering the Earth's magnetic field, bats are the teachers of humans, and dragonflies are the ancestors of airplanes." The bastard interrupted Little Fly."Hehe, what did you say? Dragonflies are the ancestors of airplanes."" Hehe, yes, this is not a dream of flying in an airplane."Little Fly Buddha said seriously,""In fact, bats are not the only creatures in nature that can act as human 'teachers'. Since ancient times, humans had wanted to fly into the blue sky like birds. The scientists studied the principle of bird flight and finally invented the airplane in 1903.”"Hehehe, you mean scientists got inspiration from dragonflies and invented airplanes? Therefore, dragonflies were the ancestors of airplanes.”Little Fly: "You're smart. Then let's share the legend of the Wright brothers 'invention of the airplane."
In the winter of 1877, a heavy snowfall fell in the Daytona region of the United States. Snowflakes fell from the sky, and some looked like lovely angels leisurely dancing in the air! Some of them were like naughty children scrambling to get to the ground to play! Snow kept falling, and snowflakes drifted down from the sky. Snowflakes fell on the tree girl, and she seemed to be wearing a white wedding dress. The snowflakes fell on the house, and the house seemed to be wearing a big white hat. Snowflakes fell on the road, and the road looked like a white scarf. Snowflakes fell all over the ground, and it was as if the ground was covered with a thick quilt. The hills in the suburbs were covered in white. A group of children came to the hillside covered in thick snow and quickly slid down on their homemade sledges. Laughter immediately rang out from the hillside.
Beside them, two boys stood quietly, watching the cheerful sledge slide down. The older boy sighed. If only we had a sledge!”
Another child pouted and said,"Who asked our father to always be away!"”He had an idea and continued,"Brother, let's do it ourselves!”When the boy who was called brother heard this, he immediately smiled and said happily,
"That's right! We can do it ourselves. Come, Orville, let's go back!" So the two children hopped down the hill and ran home.
These two brothers were the Wright brothers. The elder was called Wilbur, and the younger was Orville. They had liked to play with toys since they were young and often played all kinds of games together. Their grandfather was a craftsman who made wheels. There were all kinds of tools in the house. The two brothers treated it as their paradise and often went to see their grandfather work. As time went by, they imitated and made some small toys. Therefore, the two brothers decided to make a sledge this time and pull it to the hillside to compete with their companions. That night, the brothers told their mother about this idea. When his mother heard this, she said happily,"Alright, let's do it together!"
So, the two brothers ran to their grandfather's workshop, found a lot of wooden planks and tools, and started working without thinking.
"No," said their mother, stopping them."We have to have a plan for everything. We have to draw a pattern first, and then we can do it!”
The two brothers understood this principle and designed the design together with their mother. The mother first measured the brothers 'bodies and then drew a very short sledge. "Mom, other people's sledges are very tall. Why is your sledge so short? Will this work?" Orville asked, puzzled.
"Child, if you want the sledge to run fast, you have to make it short. This way, it can reduce the wind resistance and speed up.”her mother explained gently. The two brothers finally understood that they should not be rash in doing anything. They should first understand the reason.
A day later, the Wright brothers 'low sledge was completed. The brothers pushed it onto the hill. As soon as they placed it on the hill, a boy ran over.
"Come and see, the Wright brothers are fighting a monster!”the boy cried out in alarm.
After a while, the children gathered around and gesticulated about this strange thing. The Wright brothers did not think much of it and bravely said,""Who will compete with us?"
The boy who had run over earlier hurriedly shouted,"I'll do it! I'll compete with them!" After saying that, he pulled his sledge over.
The result of the competition was, of course, the Wright brothers 'victory. The children no longer mocked the sledge. Instead, they gathered around and looked left and right, as if they were looking for something.
The Wright brothers were very happy and went home with the joy of victory.
It was Christmas, and her father had returned from overseas. On Christmas morning, Dad gave them a present. The brothers opened it impatiently. It was an unknown toy. It looked very strange.
Dad told them that it was a flying spiral that could fly high in the air. "Only birds can fly! How can it fly!" Wilbur was a little suspicious.
His father smiled and put on a show on the spot. He twisted the rubber band on it first, and when he let go, it made a whining sound and flew high into the air. Only then did the brothers believe that other than birds and butterflies, man-made things could also fly. Therefore, the brothers took it apart and wanted to explore why it could fly into the sky.
From then on, in their young hearts, they would definitely create something that could fly high in the blue sky in the future. This wish had always affected them. In 1896, the Wright brothers saw a piece of news in the newspaper: Lilienthal of Germany died in a glider accident. This news was a huge shock to them. The brothers decided to study flying in the air.
At this time, the Wright brothers opened a bicycle shop. They worked hard to earn money while studying the information of the flying car. Three years later, they mastered a lot of knowledge about aviation and decided to make a replica of a glider.
They first observed the eagle's movements in the air, then drew them one by one, and then began to design the glider. In October 1900, the Wright brothers finally made their first glider and took it to Kitty Hawk, which was far away from Daytona. It was very remote, with no trees or houses around, and the wind was very strong, which was very suitable for flying gliders.
The brothers spent a week assembling the glider, tying it to a rope, and flying it like a kite. They succeeded. Wilbur then sat on it and tested it. Although it flew, it was only a meter high.
In the second year, the two brothers made another glider after many improvements. In the autumn of that year, they went to Kitty Hawk again. After an experiment, they reached an altitude of 180 meters.
The brothers were very happy, but they were not satisfied. They wondered if they could make a machine that could fly without wind.
The two brothers thought over and over again. They gathered all the information about flight and studied it over and over again. However, they still couldn't think of a driving force to move the huge glider and people into the air. One day, a car stopped in front of the garage. The driver asked them to borrow a tool. He was here to repair the car engine. The two brothers had an idea. They wondered if they could use the engine of a car to propel them into flight. From then on, the brothers started to think about the engine. They first measured that the maximum carrying capacity of the glider was 90 kg, so they ordered an engine that was no more than 90 kg from the factory. However, the lightest engine at that time was 190 kilograms, and the factory could not make such a light engine.
Later, an engine engineer found out about this and agreed to help the Wright brothers. After a while, the engineer created a 12-horsepower gasoline engine that weighed only 70 kilograms.
The two brothers were very happy and soon started to study how to use the engine to propel the glider. After numerous experiments, they finally installed the engine on the glider. However, they installed a propeller on the glider, which was driven by the engine.
In September 1903, the Wright brothers took their engined flight to Kitty Hawk again for a test flight. Although the test flight failed, they learned a lot from it. Not long after, they made several more test flights, either because of propeller failure, engine failure, or piloting problems.
The Wright brothers were not discouraged and continued to test their flight. At this time, an inventor named Lan Lai was commissioned by the US government to create a plane with a gasoline engine. It crashed into the sea during a test flight.
When the Wright brothers learned of this news, they went to investigate and learned a lot from Lanlai's failure. They made a rigorous inspection of every part of the aircraft and formulated strict operating regulations. On December 14, 1903, they came to Kitty Hawk again for a flight test.。
That afternoon, the brothers first placed two rails fixed to the wood on the ground, with a certain slope, so that the plane could slide conveniently. Then, they placed the plane they made on the railway.
Finally, it was the question of who would fly first. The brothers could not argue, so they had to toss a coin and let Wilbur fly first.
After Wilbur got on the plane, he lay down in the middle of the plane. After a while, he started the plane. The engine roared and the propeller slowly turned.
The plane had just glided three meters on the slope when it broke free from the iron wire at the back and rose into the air with a roar.
"It's flying!" Orville shouted excitedly.
Before he could finish his sentence, the plane suddenly slowed down and quickly fell to the ground. The entire flight time was less than four minutes.
Orville hurriedly ran forward. Wilbur had already jumped out of the fallen plane. The brothers quickly observed the plane and found that it was not damaged.
"What is the problem?" The brothers thought about it and checked one by one. There was nothing wrong with the engine, the propeller was working well, and the technical operation was completely correct.……"Brother, I know the reason!" "We used the slope to glide," Orville said with a smile."The plane took off only three meters away. At this time, the propeller had not yet reached a high speed, so it fell down in a short while.”"That's right!" Wilbur nodded and said,""We can't use the slope to take off. We have to rely on the power of the propeller to fly up. How about this, put the rail on a flat place and test it out.”
They worked for three days straight to relocate the tracks to a flat ground.
At 10 o'clock in the morning on December 17th, 1903, the sky was covered with low clouds and the wind was bone-chilling. The farmers who were invited by the brothers to watch the flight shivered in the cold and urged the brothers to fly faster.
This time, Orville was the one to test it out. He climbed onto the plane and lay down in the pilot's seat. After a while, the engine began to roar and the propeller began to turn.
Suddenly, the plane slid and rose to a height of more than three meters before flying forward horizontally.
"It's flying! It's flying!" Several farmers called out happily and followed Wilbur, chasing after the plane.
After flying for 30 meters, the plane landed steadily. Wilbur rushed forward and excitedly threw himself on his brother who had just climbed out of the plane. He shouted with tears in his eyes,"We succeeded! We succeeded!"
45 minutes later, Wilbur flew again, reaching a distance of 52 meters. After a while, Orville flew again, this time for 59 seconds, reaching a distance of 255 meters.
This was the first successful flight in human history. The Wright brothers told the news to the newspaper, but the newspaper refused to publish the news. The Wright brothers didn't care. They continued to improve their aircraft. Not long after, the brothers created a plane that could seat two people and flew in the air for more than an hour.
After the news spread, people spread the news. The US government attached great importance to it and decided to let Wright do a test flight performance.
On September 10th, 1908, the weather was unusually clear. The plane was surrounded by people watching. They were waiting excitedly for the Wright brothers to fly.
At around 10 o'clock, his brother Orville flew their plane into the sky freely amidst the cheers. The two long wings flew across the sky like an eagle spreading its wings.
People could no longer suppress their excitement. They raised their heads to the sky and called out the Wright brothers 'names. Many people's dreams had finally become a reality.
The plane flew at an altitude of 76 meters for 1 hour and 14 minutes and carried a brave passenger. When it landed, people surrounded it from all directions. Not long after, the Wright brothers, with the support of the government, founded a flight company and a flight school. From then on, airplanes became another advanced means of transportation.
Little Fly commented,"The Wright brothers were the most famous inventor of the 20th century. They were both born in the United States." In 1894, the news of the successful test flight of the glider made them determined to fly. In 1896, Rindahl's test flight accident prompted them to focus their attention on the balance control of the aircraft. They especially studied the flight of birds and delved into almost all the books on aviation theory at that time. During this period, the aviation industry suffered setbacks one after another. The flight technician Pierre's plane was destroyed, the heavy machine gun inventor Maxim failed his test flight, and the aviation scientist Langley fell into the water with his plane, and so on. However, the Wright brothers did not give up on their efforts. From 1900 to 1902, in addition to more than 1000 gliding test flights, they also made more than 200 different wings and conducted thousands of wind tunnel experiments. They corrected some of the wrong flight data of Rillindahl and designed a cross-section shape of the wing with a larger lift force. Finally, in 1903, the first plane,"Flyer 1," was built. From December 14 to 17, 1903,"Flyer 1" was on a sand dune in Kitty Hawk, North Caroline, USA. Four test flights were carried out. The first test flight was piloted by Orville Wright. It flew a total of 36 meters and remained empty for 12 seconds. The fourth flight was piloted by Wilbert, flying a total of 260 meters and remaining empty for 59 seconds. In 1906, their plane was granted a patent in the United States. They received the United States Congress 'Honorary Award in 1909. In the same year, they founded Wright Airplane Company. The Wright brothers 'great contribution was the realization of the aircraft relying on engine power and propeller thrust to carry people. In 1908, the Wright brothers improved the airplane. They installed a 22,050-Watt engine and modified the seat so that the pilot could sit in the middle of the wing to control it. That year, they held an air show in Paris, France, and set a record of two hours, 22 minutes, and 23 seconds for a continuous flight distance of 117.5 kilometers. This was the longest flight time and distance in the world at that time. The Paris air show was the most successful of the Wright brothers 'many performances in Europe. In honor of the 300th anniversary of the discovery of New York, Weberwright performed another flight. Although the flight was only a few minutes long, it greatly stimulated the enthusiasm of the American public to develop the aviation industry.
The Wright Brothers 'success in flight did not receive the attention and recognition of the American government and the public at first. It was still doubted by people until 1907. On the contrary, France was the first to give them a correct evaluation of their achievements in 1908, which set off an aviation boom that swept the world. In 1909, they were awarded the U.S. Congress 'Honorary Award. In the same year, they founded Wright Airplane Company. Wilbur. Wright died on May 29, 1912, at the age of 45. After that, Orville Wright worked hard for 30 years to make Wright aircraft company a world-famous aircraft manufacturer with a capital of up to 10 billion US dollars. Orville. Wright died on January 3, 1948.
The two brothers invented the airplane, turning the human dream of flying in the air into reality. From then on, humans had wings to fly. ---
