Who can tell the story of the Wright brothers?

Both the Wright brothers received a good education, but neither of them got a diploma. 1884 His family moved from Richmond, Indiana to Dayton, Ohio. Orville University dropped out of school in the third year (1889) and started a printing business with the help of his brother. Welber is the editor of the weekly West Side News (which became the evening news a few months later), and Orville is the publisher. Influenced by the national bicycle craze, the two brothers opened a bicycle repair shop (Wright bicycle repair shop, later became Wright bicycle company) on 1892, and began to produce their own brand bicycles on 1896. They established their interest in flying with this spirit of unremitting efforts. At the beginning of 1890, their articles in newspapers and magazines and Otto Lilienthal's plane concept map in Germany and the steam plane model of Smithsonian Institute in samuel langley successfully flew in May 1896, and then Octave Chanute, an engineer in Chicago and an authority devoted to flight research, flew several plane models in the dunes and lakeside of Michigan. This series of events caught the attention of the Wright brothers. In May 1899, Welber wrote a letter to the Smithsonian Institution, requesting aviation information and books. Based on the sketches and inspiration of Sir George Gloria, Sanute, Lilienthal, Leonardo da Vinci and Langley, the Wright brothers started their mechanical aviation experiment.

The image of the Wright brothers in the public has always been one, and they enjoy the fruits and honors of their own inventions. James tobin, a careful biographer, found that "My Machine" and "My Plan" written by Welber at 1899- 1900 were both changed from the singular of the first person to the plural of "we" and "ours". "It's hard to imagine how a smart and outstanding person like Orville succeeded. From a small shop in Ohio to consulting capitalists and presidents, Orville did it. He is a leader from beginning to end. "

After the Wright brothers finished all the theoretical research, they began to practice. Their bicycle shop assistant charles taylor became an important member of the team, and the three of them made the first airplane engine together. [Edit this paragraph] The story of inventing the airplane1In the winter of 877, there was a heavy snow in Dayton, USA, and the hills in the suburbs were covered with snow. A group of children came to the hillside covered with thick snow and slid down quickly in a homemade sleigh. Laughter broke out on the hillside.

Next to them, two boys stood quietly, watching the cheerful sledge pass from top to bottom. The big boy sighed, "Hi! If only we had sledges, too! "

Another child pursed his lips and said, "Who told us that dad was always away!" " "He had a brainwave and then said," Brother, let's do it ourselves! " Hearing this, the boy called brother immediately laughed and said happily:

"Yes! We can do it ourselves. Come on, Orville, let's go back! " So, the two children jumped off the hillside and ran home quickly.

The two brothers are the Wright brothers, the elder brother is Welber and the younger brother is Orville. They like to play some things since childhood and often play all kinds of games together. Their grandfather is a craftsman who makes wheels. There are all kinds of tools in the house. The two brothers regard this place as their paradise and often go to see his grandfather's work. After a long time, they imitated and made some small toys. So, the two brothers decided to build a sledge this time and pull it to the hillside to compete with their companions. That night, the two brothers told their mother the idea. Hearing this, my mother said happily, "OK, let's do it together!" " "

So, the two brothers ran to grandpa's workshop, found a lot of sticks and tools, and did it without thinking.

"No," their mother stopped them from saying. "We must do everything in a planned way. We have to draw a picture first and then do it! "

The two brothers understand this truth and design patterns with their mother. Mother measured the bodies of the two brothers first, and then drew a short sledge. "Mom, someone else's sleigh is very high. Why is your sleigh so short? Will this work? " Orville, the younger brother, asked.

"Son, if you want the sledge to run fast, you have to shorten it, which will reduce the wind resistance and make it much faster." Mom explained gently. The two brothers realized that nothing should be done rashly, and they should first find out the truth.

A day later, the Wright brothers' short sleigh was made. The two brothers pushed it to the mountain, and just after putting it on the hillside, a boy came running.

"Look, the Wright brothers have brought a monster!" The boy started to cry in a fuss.

After a while, all the children gathered around and talked about this strange thing. The Wright brothers disagreed and bravely said, "Who is better than us!"

The boy who ran over earlier quickly shouted, "I'll come!" " I will compete with them! "Say that finish, he pulled up his sledge.

The result of the game, of course, is that the Wright brothers won. Instead of laughing at the sled, the children gathered around and looked around as if they wanted to find something from it.

The Wright brothers were very happy and went home with the joy of victory.

Christmas is coming, and my father is back from other places. On Christmas morning, their father gave them a present, and the two brothers eagerly opened it. That's an unknown toy. It looks strange.

Dad told them that this is a flying spiral that can fly very high in the air. "Birds can fly! How can it fly! " Welber is a little skeptical.

Dad smiled and performed live. I saw him twist the rubber band on it first. As soon as he let go, it flew into the sky with a loud noise. Only then did the two brothers believe that man-made things can fly into the sky besides birds and butterflies. So, the two brothers took it apart and wanted to explore why it could fly to the sky.

From then on, in their young hearts, things that can fly high in the blue sky will be created in the future. This wish has been affecting them. 1896, the Wright brothers read a news in the newspaper: German Lilienthal died in a glider accident. The news shocked them so much that the two brothers decided to learn to fly.

At this time, the Wright brothers opened a bicycle shop. They learn flight information while working to earn money. Three years later, they learned a lot about aviation and decided to copy a glider.

They first observed the movements of eagles flying in the air, then drew them one by one, and then set about designing gliders. 1900 5438+00 in June, the Wright brothers finally built their first glider and took it to the Kitty Hawk, which is far away from Dayton. It is very remote, there are no trees and houses around, and the wind here is very strong, which is very suitable for flying gliders.

The two brothers spent a week installing the glider, first tied it to a rope and flew it like a kite. The result was successful. Then Welber sat on it and did the experiment. Although it flew, it was only 1 m high.

In the second year, the two brothers made a glider after many improvements on the basis of the last one. This autumn, they came to the seaside of Kitty Hawk again. After an experiment, the flying altitude suddenly reached 180 meters.

The two brothers were very happy, but not satisfied. They want to know if they can make a machine that can fly without wind.

The two brothers thought over and over again, collected information about flying, studied it over and over again, but never thought about using any power to transport pet gliders and people into the air. One day, a car stopped in front of the garage and the driver borrowed a tool from them. To repair the engine of the car. Two brothers had a brainwave. Can they use the engine of the car to propel the flight?

Since then, the brothers have been thinking about the engine. They first measured that the maximum carrying capacity of the glider was 90 kilograms, so they ordered an engine of no more than 90 kilograms from the factory. But the lightest engine at that time was 190 kg, and the factory could not make such a light engine.

Later, an engine engineer learned about it and promised to help the Wright brothers. After a while, the engineer really built a gasoline engine with 12 horsepower and a weight of only 70 kg.

The two brothers were very happy and soon began to study how to use the engine to propel the glider. After countless experiments, they finally installed the engine on the glider, but only installed the propeller on the glider. The engine drove the propeller to rotate and drive the glider to fly.

In September 1903, the Wright brothers took their engines to the Kitty Hawk Sea for another test flight. Although the test flight failed, they learned a lot from it. Soon after, they made several test flights in succession, either because of propeller failure, engine failure or driving technical problems.

Undaunted, the Wright brothers still insisted on the test flight. Just then, an inventor named Langlai was commissioned by the American government to build a plane with a gasoline engine and fell into the sea during the test flight.

After learning the news, the Wright brothers went to investigate, learned lessons from Langley's failure and gained a lot of experience. They made a strict inspection of every part of the plane and formulated strict operating procedures. 1903 12 14 They came to Kitty Hawk for flight test.

This afternoon, the two brothers first put two rails fixed on wood on the ground with a certain inclination, so that the plane can slide easily. Then, put the plane they made on the track.

Finally, there is a question of who will fly first. The two brothers were at loggerheads and had to flip a coin to decide who would fly out of Welber first.

After boarding the plane, Welber lay in the middle of the plane and soon started the plane. The engine roared and the propeller turned slowly.

After taxiing on the slope for 3 meters, the plane broke free from the wire tied behind it and roared into the air.

"It's flying!" Orville shouted excitedly.

As soon as the voice fell, the plane suddenly slowed down and soon fell to the ground. The whole flight time is less than 4 minutes.

Orville rushed forward. Wilbur had jumped out of the falling plane, and the two brothers soon observed that the plane was not damaged.

"What's the problem?" The two brothers thought about it and checked it one by one. There is nothing wrong with the engine, the propeller rotates well and the technical operation is completely correct. ...... "Brother, I know why!" Orville said with a big smile: "We used the slope to slide, and the plane took off only 3 meters away. At this time, the rotation of the propeller has not reached high speed, and it will be planted in a short time. " "Yes!" Welber nodded yes, and then said, "We can't take off by taxiing on the slope, but we must rely on the power of the propeller to fly. Well, put the track on a flat place and try again. "

They worked continuously for three days, and then re-laid the tracks on the flat ground.

1903 12 17 in the morning 10, the sky was cloudy and the wind was biting. The farmers invited by the two brothers to watch the flight were shivering with cold and repeatedly urged the two brothers to fly quickly.

During Orville's test flight, I saw him climb on the plane and lie in the driver's seat. After a while, the engine began to roar and the propeller began to turn.

Suddenly, the plane skidded, rose to a height of more than 3 meters, and then flew forward horizontally.

"fly! Fly! " Several farmers cried happily, followed Welber and ran after the plane.

After flying 30 meters, the plane landed firmly. Welber rushed forward and pounced on his younger brother who had just climbed out of the plane. With tears in his eyes, he shouted, "We made it! We succeeded! "

After 45 minutes, Welber flew again, with a distance of 52 meters. After a while, Orville flew again, this time for 59 seconds, with a distance of 255 meters.

This is the first successful flight in human history. The Wright brothers told the news to the newspaper, but the newspaper didn't believe it and refused to publish it. The Wright brothers don't care. Continue to improve their plane. Soon, the two brothers built a plane that could take two people, and they flew in the air for more than an hour.

After the news spread, people rushed to tell each other. The American government attached great importance to it and decided to let Wright do a test flight performance.

1908 September 10, the weather was exceptionally clear, and the ground over which the plane flew was surrounded by people watching. People are in high spirits, waiting for the Wright brothers to fly

At about 10, my brother Orville flew their plane freely into the sky with cheers. Two long wings crossed the air, just like an eagle spreading its wings and flying.

People can no longer restrain their excitement, holding their heads high in the sky calling the names of the Wright brothers. Many people's dreams have finally come true.

The plane flew at an altitude of 76 meters 1 hour 14 minutes, carrying a brave passenger. When it landed, people gathered from all directions. 1908, with the support of the government, the Wright brothers founded a flight company and a flight school. Since then, airplanes have become another advanced means of transportation for people.
