The invention story of the Wright brothers, about 200 words
The elder brother Wilbur Wright was born in April 1867, and the younger brother Orville Wright was born 4 years later. At a young age, the brothers had already demonstrated their special abilities in mechanical design and maintenance. They are good at thinking and full of fantasy. Whenever they are free, the brothers either discuss the structure of a certain machine or go to watch the craftsmen repair the machine. They are skilled in craftsmanship and often make many innovative small toys, such as sleds that can turn freely and so on.
One day, his father returned from a business trip and brought a gift to the Wright brothers: a flying butterfly. The father gently gave the toy a boost, and the little thing started to fly in the air. The two little brothers were very happy, but they felt that it could not fly far enough, so they made several larger ones imitating the toy. Some of these imitations were able to fly over trees, and some flew dozens of meters away, but one of the brothers' very large imitations failed. But this did not make them sad, but instead inspired the brothers to create an airplane.
In 1894, the Wright brothers opened a bicycle store in Dayton. Because they work hard, have good craftsmanship, and have reasonable prices, the store's business is booming. The innovative Wright brothers were certainly not satisfied with these. They did not want to deal with these bicycle parts for the rest of their lives, so they decided to start realizing their childhood dreams.
The Wright brothers’ idea of ??building an airplane was appreciated by the Smithsonian Institution. The vice president wrote a passionate letter and sent many reference books. The two brothers were greatly encouraged. Whenever they had time, they dived into the pile of books and devoured the basic knowledge of aviation. Soon, they had the ability to build airplanes.
In October 1900, their first glider made a test flight. However, the results of the test flight were unsatisfactory. The aircraft could only barely take off and was very unstable. What was the problem? After careful examination Only after analysis did we know that the previous materials they used had theoretical errors. So they built a wind tunnel to correct the data through experiments and design the aircraft.
This wind tunnel is just a wooden box 6 feet long and 12 inches wide on each side. At one end of the box, a blower blows air in at a certain speed. Compared with modern high-speed wind tunnels, it is extremely crude, but this small auxiliary tool helped the brothers a lot, and they drew many new conclusions through it. Based on it, the brothers succeeded in designing a third glider that could fly safely and smoothly in both strong and light winds.
After all, the glider's airtime is limited, but if the aircraft is powered and carries enough fuel, it can fly, take off and land freely. As a result, the brothers began the development of powered aircraft.
The Wright brothers worked day and night, and soon they designed an efficient engine and a high-efficiency propeller, and then successfully assembled the various components into the world's first powered airplane

Wilbur Wright was born on April 16, 1867, and his younger brother Orville Wright was born on August 19, 1871. They had a passion for mechanical assembly and flight since they were young. Have a strong interest in bicycle repair and manufacturing industry. The Wright brothers originally made a living by repairing bicycles. The two brothers were smart and studious. Since 1896, they have been enthusiastic about flight research. Through many studies and experiments, they quickly came to a conclusion: To solve the key unresolved problem of aircraft control, some kind of mechanical device that can make aerodynamics work must be installed. They followed this idea and after several hot and cold tests of a manned glider over the Kitty Hawk Sand Dunes, their dream finally became a reality.
The news of Otto Lilienthal's successful glider flight made them determined to fly. The crash of Lilienthal's test flight in 1896 prompted them to focus on the balance control of the aircraft.
They studied the flight of birds in particular and delved into almost every book on aeronautical theory written at the time. During this period, the aviation industry suffered successive setbacks. Pilot Peel's plane crashed and killed, Maxim, the inventor of the heavy machine gun, failed in his test flight, and aeronautical scientist Langley fell into the water with his plane and people, etc. This made most people think that the aircraft relied on itself. Powered flight was completely impossible.
The Wright brothers did not give up their efforts. From 1900 to 1902, in addition to conducting more than 1,000 gliding test flights, they also made more than 200 different wings and conducted thousands of wind tunnel experiments, correcting some of Lilienthal's erroneous flight data. , designed a wing cross-section shape with greater lift. After all, the glider's airtime is limited, but if the aircraft is powered and carries enough fuel, it can fly, take off and land freely. As a result, the brothers began the development of powered aircraft. The Wright brothers worked day and night, and soon they designed an efficient engine and efficient propeller, and then successfully assembled the various components into the world's first powered airplane. In 1903, they built the first aircraft to fly manned under its own power, "Aviator" No. 1. The aircraft had a wingspan of 13.2 meters, an elevator in front, a rudder in the rear, and two pairs of two-blade propellers. Driven by a chain, the landing gear is skid-type and is equipped with a 70kg, 8.8kW four-cylinder engine. This famous aircraft in aviation history is now on display at the Air and Space Museum in Washington, USA.
The "Aviator" is an ordinary biplane. Its two pusher propellers are installed on both sides of the driver's position and are chain-driven by a single engine. In 1904, the Wright brothers built the second "Flyer" equipped with a new engine and conducted a test flight at Hoffman Prairie near Dayton. The longest sustained flight time was more than 5 minutes and the flight distance was 4.4,000 miles. meters; in 1905, the third "Aviator" was tested, piloted by Wilbur, and it lasted 38 minutes and flew 38.6 kilometers. On the day of the first test flight, the weather was cold and windy. First, his brother Orville Wright piloted the "Aviator" aircraft, staying empty for 12 seconds and flying 36.5 meters. On the same day, the plane made three more flights, with the best result being his brother Wilbur Wright. He flew the plane continuously for 260 meters in the air.
From December 14 to 17, 1903, "Aviator" 1 conducted its fourth test flight on a sand dune in Kitty Hawk, Kitty Hawk, North Carolina, USA. The first test flight, piloted by Orville Wright, flew 36 meters and remained empty for 12 seconds. The fourth time was by Wilbur. Piloted by Wright, the aircraft flew 260 meters and remained airborne for 59 seconds. In 1906, their aircraft was patented in the United States.
The success of the Wright Brothers' flight was not initially valued and recognized by the American government and the public. It was still doubted by people until 1907. Instead, it was France that first gave their achievements a correct recognition in 1908. ’s evaluation has since set off an aviation craze that has swept the world. For this reason, they finally received the U.S. Congressional Medal of Honor in 1909. In the same year, they founded the "Wright Aircraft 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 tens of billions of dollars. Orville. Wright died on January 3, 1948.
The Wright brothers have loved drawing, designing, and making toys since they were young. One Christmas, their father gave them a toy that could fly in the air. The two brothers were so excited to play that they came up with the idea of ??letting people fly into the sky.
When the Wright brothers grew up, they ran a bicycle repair shop and continued their exploration and research on aircraft. One day, they heard about the death of a German glider expert (Li Lindahl) due to a glider crash. This incident greatly touched them. The two brothers were determined to develop an aircraft that could safely bring people into the air.
Whenever the Wright brothers had free time, they observed the flight of birds, and soon they made their first glider. But during the test flight, the glider only flew one meter high before landing. Summarizing the reasons for their failure, they tried to install the car engine on the glider. This time, although the glider could fly a little further, it still fell down because the engine was too heavy.
The brothers continued to make improvements to the propeller and engine. An engineer helped them design a powerful and lightweight engine to solve the power problem of flight. In 1903, the younger brother piloted the "Flight" for a test flight. The aircraft landed safely after flying in the air for 12 seconds. The two brothers hugged tightly in excitement. They opened the first page of human flight history.
The brothers continued their research, and in 1908, the aircraft they developed flew for a total of 2 hours and 20 minutes. The Wright brothers finally realized the dream of mankind flying into the sky.
The story of the invention of the dragonfly is about 200 words
Scientists invented the helicopter based on the dragonfly. Scientists modified airplane wings based on dragonflies. The father of the Wright brothers
The Wright brothers, the inventors of the airplane, were envious of the birds flying in the sky when they were herding sheep when they were children, so they learned to fly like birds. Their father did not laugh at or stop them, but fully understood the children's valuable curiosity and bold ideas, and also learned to fly with the children. He solemnly encouraged the children and said, as long as you work hard, I believe you will be able to fly when you grow up! There are many reasons why the Wright brothers later invented the airplane, but I think it was my father’s understanding, appreciation, respect, and encouragement that sowed the seeds of success for the two brothers. The Wright brothers’ speech
Brother Wright took the stage and gave a speech Short speech: "As far as I know, the only birds that can talk are parrots, and parrots cannot fly high."
This concise and concise speech accurately explains that a person can only talk. (Empty words) Without action, you won’t accomplish much.
If wonderful and rational speeches are also included in essays, we should not forget the wonderful speech of only 23 words by the Wright brothers. After the Wright brothers successfully flew the world's first airplane into the sky in 1903, at a welcome reception, everyone unanimously asked the Wright brothers to give a speech. However, they declined. The elder brother came to the stage and gave a brief speech: "As far as I know, Among birds, only parrots can talk, but parrots cannot fly high." This concise and concise speech accurately elaborated the argument that only humans can be the masters of nature. Information about the Wright Brothers
The brothers are the sons of Milton Wright, an American bishop. Their childhood lives were as ordinary as those of other American children. I occasionally skipped school when I was studying. Wilbur loved skating, and Orville was fascinated by things like collecting old metal. Both brothers were very smart, but Wilbur loved reading more and took Greek and mathematics as electives. Orville was very naughty at school and got into so many troubles that he was expelled. Both brothers received some degree of higher education, but neither received a college diploma. Wilbur and Orville were talented in mechanics and both had a keen interest in flying. One day in the late 1870s, their father gave the brothers a gift that could fly to the ceiling if thrown into the air. This gift made the Wright brothers have a great interest in flight and inspired their dream: to fly in the sky like a bird. Mother Susan Wright was smart and capable and could do everything. She even made her son's sled. The Wright brothers' hands-on ability was deeply influenced by her. They started by making paper airplanes, then used gliders (without engines) to learn to fly, and experimented more than a thousand times. They continued to practice, explore, and seek help from experts, and finally succeeded in staying in the air for three and a half minutes on December 14, 1903. Later, they continued their efforts, continuously improved their technology, and developed the world's first aircraft.
The Wright Brothers refer to Orville (August 19, 1871 - January 30, 1948) and Wilbur (April 16, 1867 - May 30, 1912). American. The world generally believes that on December 17, 1903, they completed the first fully controlled flight with on-board external power, the body was heavier than air, and continued to stay in the air without landing, and thus credited with the invention of the world's first practical aircraft. to them.
