On December 17, 19o3, Orville Wright was driving.
With the "Flyer 1", it successfully carried out a controlled flight in the air that lasted 12 seconds. This is the turning point of humanity's transformation from fantasy to reality. Orville Wright (1871-1948) was the younger brother of Wilbur Wright (1867-1912).
A native of Dayton, Ohio, USA. When they were young, their father gave them a toy helicopter. Its structure is a flying spinning top.
Its principles have always been etched in their hearts, inspiring them to devote themselves to a lifelong interest in flight experiments and research.
In order to provide a steady stream of financial support for research flights, the brothers worked together to run a bicycle business. At the same time, they are gaining more and more knowledge about the machine. The Wright brothers studied diligently and assiduously studied a large amount of literature:
From the history of the earliest attempts to fly, to the latest reports of experiments. As they carefully observed the movements of various birds, they noticed that whenever the birds turned, they tended to turn and twist their wingtips and wingsides to maintain their balance. So I applied this principle to the design of the aircraft, which was something that no one had thought of before, but it was a very critical issue.
After two years of exploration, the Wright brothers have figured out the basic principles of gliding from more than 1,000 glidings and obtained a large amount of valuable data.
This has provided them with experience in the development and flight of aircraft in the future. In 1903, the Wright brothers developed an airplane with an internal combustion engine。They attached propellers made of long pine wood to a 70-kilogram internal combustion engine.
The plane looks like a bulky bookshelf. For this reason, people call it the "flying bookshelf". On December 14, 1903, the Wright brothers made their first test flight.
With the roar of the internal combustion engine, this "flying bookshelf" was only a second off the ground, but it attracted a burst of cheers from the onlookers. On December 17, the Wright brothers conducted another test flight. The younger brother, Orville Wright, confidently sat in the pilot's seat.
The plane started, the spiral turned up, and the ground rolled up with bursts of yellow sand. After a while, the plane was off the ground, and after 12 seconds in the air, it landed safely at an altitude of 30 meters. The onlookers cheered.
Take a break and switch to his brother Wilbur Wright for a test flight. The flight distance has been increased from 37 to 260 meters, and the flight time has been extended from 12 seconds to 59 seconds.

They invented the airplane on their own wits alone, and this has nothing to do with being sociable.
-
At the beginning of the 20th century, there was a pair of brothers in the United States who made significant contributions to the history of the world's aircraft development, the Wright brothers.
-
Because they wanted to fly, this invention brought great convenience to mankind.
-
They wanted to contribute to the country and the world, and constantly researched the institute to invent the airplane.
-
For scientific research, you don't need to be very sociable, just have your own ideas.
-
Because they may be very strong themselves, they don't need anyone else to invent their own.
-
This is because they have had the dream of flying into the sky since they were young, so they were able to invent airplanes.
-
Because they had a dream of flying from a very early age, they invented the airplane.
-
They are all making a fortune in silence, so they just study and become famous in one fell swoop.

1. The airplane was invented on December 17, 1903 by the Wright brothers, an American inventor.
On December 17, the Wright brothers made their first test flight of a fully controlled, self-powered, heavier-than-air fuselage, which remained in the air without landing, that is, the world's first aircraft, the "Flyer One".
3. The "Flyer 1" is a biplane with two propulsion propellers mounted on both sides of the pilot's position and chained by a single engine. The steering system adopts a canard layout with the elevator in front and the rudder in the rear, which is where the Wright brothers' greatest contribution to aviation lies.
4. Li Lindal had to move his body and control the aircraft to fly by changing the center of gravity, while the pilot of the "Flyer 1" used a mechanical device to curl the entire wingtip to achieve the same goal. The climb and dive of the aircraft relied on a pair of biplane elevators mounted in the front of the aircraft; A pair of rudders are connected to each other with the wing curling mechanism and are mounted behind the pilot.
5. The Wright brothers pioneered the flight control system that allowed the aircraft to fly in a controlled manner, thus laying the foundation for the practical application of the aircraft, and this technology is still used in all aircraft today. The Wright brothers' great inventions changed human transportation, economy, production, and daily life, as well as military history.

The Wright brothers of the United States, the designers of the first powered aircraft in human history, made a modest contribution to the creation of modern aviation. Their stories are told all over the world.
One day, after returning from a business trip, his father brought the Wright brothers a gift: a flying butterfly. Father gently energized the toy, and the little thing flew in the air.
The little brothers were overjoyed, but they felt that they had not gone far enough to make a toy like a toy.
Some of these imitations were able to fly over trees, and some flew tens of meters away, but one of the brothers' large-sized imitations failed. But this did not upset them, but instead aroused the brothers' idea of building an airplane.

The Wright brothers were great inventors, and their invention of the airplane at the beginning of the last century was definitely one of the greatest inventions in human history.
In fact, many years before the Wright brothers, there were many people who tried to fly, but failed, and later invented balloon flight, but the balloon was not easy to control and slow.
Inspired by the fact that air currents can drag thin objects, the Wright brothers invented an airplane that could fly, and although the Wright brothers invented the airplane to fly at an altitude of only two meters and fly tens of meters, it heralded the arrival of the age of human aviation.
I'm also very inferior, I also have a friend of the opposite sex who is very inferior, I wondered, in fact, he is very good and good, I don't know where the inferiority complex comes from. >>>More
Leos seem to have such a character, whether they are facing love or everything in life. That is, if they choose what they want, what they want in their hearts, then they never care if it is right or wrong, even if everyone around them is against it, they will never look back. So it is conceivable that Leo will inevitably present such a state in love, from beginning to end.
Compare the heart to the heart, you try to open the heart door, you are sincere, you will have more friends, now people have QQ groups, WeChat groups, you can chat more in the group, on the Internet, who doesn't know who, boldly chat with the people in the group, slowly know how to chat with people, find a common topic for everyone, and the atmosphere will chat. The atmosphere is up, chatting is very happy, I used to not like to talk, I just like to listen to others, but people who talk less, there are few disasters, and you can exercise your observation, I have read psychology before, so to a strange environment, contact with strangers is also not like to talk, slowly observe them, I also know, you can chat with them, and you can talk very happily. Chat with the girl you like, you will be scared, afraid of saying the wrong thing, right, in fact, it is your own mental role, is that people have shortcomings, as long as you can explain it well, it's okay, I wish you to catch up with the girl you like as soon as possible.
Being a kindergarten teacher has not been able to change your personality, you should find a confidant. Finding a psychiatrist can also be comforting. When people are most helpless, they need someone to enlighten them, and someone to care for and help them. If you can't find it, you can talk to me.
Well! A little, I'm also a Pisces, maybe he's more introverted and shy and hasn't had any emotional experience, in that little word, it's called the emotional brain has not been opened, usually more enlightened and enlightened him, don't keep it in your heart, even if it's angry with him, it doesn't matter, you have to explain it to him before he understands, otherwise he's really stupid! ~
