The story of the invention of the airplane be short! ）

The inventors of the airplane were the Wright brothers, the famous American inventors.

The Wright brothers have had a natural love for mechanics since they were children, and they have loved to dismantle and manipulate since they were children. One day, their dad brought back a flying spiral toy and told them that it could fly high in the air. Only then did my brother believe that in addition to birds and butterflies, artificially made things could also fly into the sky.

Growing up, the brothers began their experiments with mechanical aviation, and observing birds, began the development of flying machines.

On December 17, 1903, the Wright brothers made their first test flight of an airplane that was completely controlled, self-powered, the fuselage was heavier than air, and remained in the air, that is, the world's first aircraft, the "Aviator I". Their great inventions changed human transportation, economy, production, and daily life, and at the same time changed military history.

Principles of airplane flight.

The cross-section of the wing of an aircraft is generally rounded and blunt at the front and sharp at the rear, with an arched upper surface and a flat lower surface. When equal mass air passes through both the upper and lower surfaces of the wing, different flow velocities are formed above and below the wing.

The velocity of air passing through the upper surface of the wing is high and the pressure is small; When passing through the lower surface, the flow velocity is small and the pressure is strong, so the aircraft will have an upward resultant force, that is, the upward lift, due to the existence of lift, so that the aircraft can leave the ground and fly in the air. The faster the aircraft flies and the larger the wing area, the greater the lift generated.

The Wright brothers have been working on airplanes since 1896.

While opening a bicycle shop to make money, they also had to accumulate aviation knowledge, observe eagle flights, repeatedly design drawings, and after more than three days and nights of preparation, in October 1900, the Wright brothers made a glider powered by the wind.

The story of the Wright brothers, the inventors of the airplane, the designers of the first powered aircraft in the history of mankind.

The flyfly is one of the insects and can be said to be the champion of flight. Inspired by it, people began to fantasize about building an airplane that could rise directly from the ground without a runway. The Wright brothers were the first to build a model of a helicopter.

In 1907, the world's first fly-like helicopter was developed by French breeders Burleg and Richer. The helicopter had no wings, and the fuselage was flanked by a long arm, each with two four-bladed propellers that rotated horizontally; When the four sets of propellers turn, the *** can be raised vertically from the ground. During the test flight, it was found that the aircraft vibrated badly and had poor safety performance.

After experiments, people found that the key is to design the most ideal rotor transmission mechanism. In this regard, the inventors spent decades, until 1930, after repeated experiments, Professor Fokker of Germany finally designed an ideal rotor and mechanical transmission, during the test flight the pilot did not have to worry about his own safety, and the plane flew in a balanced manner. Two years later, the American engineer Sikorsky designed a more practical ***, and Sikorsky drove it to a successful performance.

Less than a year later, the former Soviet engineer Bratukhin also independently designed and built a *** called "Omega". Since then, *** has become an important tool for air traffic. It is widely used in many fields such as military, geodesy, forest fire prevention, agricultural fertilization and spraying, and sea rescue.

With the continuous development of science and technology, helicopters are also constantly improving and performing better.
