The origin and development of airplanes in what era was the airplane invented and what animals start

The invention of the airplane was inspired by birds, and the inventors of the airplane were the Wright brothers.

In their research, the Wright brothers took great care to learn directly from living flying creatures, birds. They often lie on their backs on the ground, carefully observing the eagle's flight in the air for hours on end, studying and pondering the mechanisms by which they take off, rise and fall, and circle. Many of the novel ideas they put forward at that time were later in the aviation industry.

has been applied.

On December 17, 1903, the Wright brothers made their first test flight of a fully controlled, self-propelled, heavier-than-air fuselage, and continuously stuck in the air, that is, the world's first aircraft, the "Flyer One".

Principles of flight of airplanes:

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.

Airplanes were invented based on birds.

One of the most significant inventions of the twentieth century was the birth of the airplane. Since ancient times, humans have dreamed of flying in space like birds. The airplane is recognized as having been invented by the American Wright brothers.

Their flight on December 17, 1903, was recognized by the Fédération Internationale de Nautical (FAI) as "the first controlled, sustained powered flight of a heavier-than-air aircraft", and in the same year they founded the Wright Aircraft Company.

Since the invention of airplanes, airplanes have increasingly become an indispensable means of transportation for modern civilization. It profoundly changed and affected people's lives, and opened the history of people's conquest of the blue sky.

Take-off and landing

The take-off of an airplane depends on the lift generated by the relative motion with the air, and the magnitude of the lift depends on the relative speed of the aircraft with the air, not the relative speed of the aircraft with the ground. If taking off against a headwind, the aircraft taxiing speed is opposite to the direction of the wind speed, and the relative velocity of the aircraft and the air is equal to the sum of the two. At this point, the aircraft only needs a small glide speed to get the lift it needs to get off the ground.

As a result, the distance required to take off against the wind will be shorter than if it were to take off without wind. Conversely, if taking off downwind, the aircraft needs to reach a higher taxiing speed to get the lift required from the ground, and the glide distance is relatively longer.

Airplanes were invented from birds.

As early as ancient times, human beings were very envious of birds that could fly freely in the sky, and always wanted to fly in the sky like birds, which was the original power for human beings to make airplanes.

Later, people learned to make kites and use the power of the wind to move in the sky, but its movement was passive and could not be done as they pleased.

More than 130 years ago, there was a pair of little brothers in the United States, which were the Wright brothers, who became famous in the future.

One day, my father brought the Wright brothers a gift: a butterfly that could fly. So the little brother imitated the toy and made a few bigger ones.

Some of these imitations were able to fly over trees, some flew tens of meters away, and then a very large imitation of the brothers failed. But this did not upset them, but instead aroused the brothers' idea of building an airplane.

They burrowed into the stacks of books and read the basics of aviation voraciously. Soon, they had the ability to build a flying mill.

In October 1900, their first glider flew in a dead end, but the results were unsatisfactory, and the plane barely rose into the air and was very unstable.

Soon, they designed a high-performance engine and a high-efficiency propeller, and then succeeded in assembling the various components into the world's first powered aircraft, and successfully flew around the figure 8.

The airplane is one of the most significant inventions of the early 20th century, recognized by the American Wright brothers.

Invent. Airplanes were invented based on what animals:

People imitate the wings of birds, and use high-power lightweight engines to drive the propellers.

After that, the desire to fly into the sky was fulfilled.

Most aircraft consist of wings, fuselage, tail, landing gear, control systems, and powerplant, each with its own unique function. During the landing of the aircraft, the aircraft needs to maintain sufficient lift while constantly decelerating to ensure that the aircraft can descend smoothly. Airplanes, on the other hand, take off by relative motion to the air.

The amount of lift produced depends on the relative velocity of the aircraft with respect to the air.

Aircraft can be divided into two categories: military aircraft and civil aircraft according to their use. Military aircraft refer to aircraft used in various military fields, while civil aircraft generally refer to passenger aircraft, cargo aircraft, agricultural aircraft, ambulance aircraft, etc.
