Was the principle of the take off of the plane inspired by the birds?

Yes. Scientists were inspired by the size of the bird's body when it flew up, and built the current airplane.

It was indeed inspired by birds, because they saw that birds could fly freely in the air, and then they designed similar curved-wing planes.

The plane took off because the birds were inspired. Because you see birds flying in the sky, let's do it and make something like an airplane.

The principle of airplane take-off is inspired by birds. At that time, people were more eager for the sky, and they saw inspiration from the little birds.

The principle of airplane take-off is indeed inspired by birds, because their take-off and landing are very similar to those of birds.

The principle of the aircraft flying up is that when the air of equal mass passes through the upper surface and the lower surface of the wing at the same time, the air will form different flow velocities above and below the wing, the air flows through the upper surface of the wing at a large velocity and the pressure is smaller, and the flow velocity is smaller and the pressure is strong when passing through the lower surface, so that the pure rock of the aircraft will have a resultant force of the upward nucleus, that is, the upward lift, due to the existence of lift, the aircraft can leave the ground and fly in the air.

The invention of the airplane originated from the human yearning for flight and the study of birds, in modern times, due to the development of aerodynamics and mechanics, people gradually understood the principle of bird flight, is due to the shape of the bird's wings, the speed of the air flow through the upper surface of the wing is faster than the speed of the flow through the lower surface, resulting in the upward air pressure on the lower surface is greater than the downward air pressure on the upper surface, this pressure difference is lift, and thus the aircraft is manufactured.

Flying "chickens" were invented according to the principle of bird flight(Knife t t.)

Airplanes fly with lift, fixed wings that provide pull through their engines. Airplanes are one of the greatest inventions of the 20th century, invented by the Wright brothers, and are now one of the more common means of transportation at high speeds.

1. The lift of the aircraftThe upper surface of the wing of the aircraft is arched, and the lower surface is flat. When the same air passes through the upper and lower surfaces of the wing, different velocities are formed above and below the wing. As the air passes through the upper surface of the wing, the velocity is high, so the pressure is low.

The flow velocity is small when passing through the lower surface, so the pressure is relatively large. At this time, the aircraft will form an overall upward resultant force, which is the lift of the aircraft. Because of the presence of lift, the aircraft can leave the ground and fly in the air.

Second, the pull of the aircraft The gravity of the aircraft is affected by the weight of the aircraft itself and the fuel it carries, and is opposite to the direction of lift. The magnitude of the aircraft's pulling force is determined by the power of the engine, and the pulling force will cause the aircraft to fly forward in the air. In general, the more powerful the engine, the greater the pulling force generated, and the faster the aircraft will fly.

When an airplane flies in the air, it is subjected to air resistance, which is in the opposite direction to the pulling force, which limits the speed of the aircraft.

3. Take-off of the aircraftThe aircraft takes off by the relative motion with the air to generate lift, and the magnitude of the lift depends on the relative speed of the aircraft and the air. If taking off in a headwind situation, the speed of the aircraft is opposite to the wind speed. The relative velocity of the aircraft to the velocity is equal to the sum of the two, and the aircraft only needs a small velocity to get the corresponding lift.

As a result, the distance required for take-off against the wind will be shorter than in windless conditions. In the process of gradual landing, the plane must continue to slow down while maintaining enough lift to make the plane fall smoothly.

When the plane takes off, it will accelerate on the runway, and because the flank design of the aircraft is ingenious, using the theory in physics, the pressure is small where the flow speed is large, so the pressure on the side of the plane is less than the bottom, so it flies.

The airplane affects the air through speed and wings, so that the density of the air below the plane increases and the density above decreases, so as to lift the plane for takeoff.

The special structure of the aircraft allows the plane to move at high speed on the ground when the pressure above the plane is smaller than that below, and the plane takes off when it reaches a certain Chengdu.

The plane takes off according to the principle of flight of birds. Humans first studied the principles of bird flight, and eventually invented airplanes.

The airplane takes off by Bernoulli's principle, that is, the greater the flow velocity of the fluid, the lower its pressure, and the smaller the flow velocity, the greater the pressure.

It should be the pulling force created by cutting the air.

Correct] Archetypal heuristics refer to the inspiration of the information that Shengho Kei obtains in other things or phenomena to solve the current problem. The thing or phenomenon that has an enlightening effect is called an archetype. There are many kinds of things or phenomena that are archetypes, and they exist in nature, human society, and daily life.

The argument mentioned in the stem is an example of the archetype inspiration, so it is correct.

The flight principle of the aircraft is that during the flight, through the wing design of the aircraft, the air flow rate changes, and under the action of these forces, the aircraft can achieve flight in the air.

According to Bernoulli's principle, the greater the flow rate of a fluid (including air flow and water flow), the smaller its pressure; The smaller the flow velocity, the greater the pressure.

When the pressure ratio between the upper and lower wings reaches an optimal lighting balance, coupled with the power of the engine itself to drive the forward traction of the propeller rotation or the forward thrust generated by the jet, the two can be combined to fly.

At the same time, the speed of the air will also change according to the speed of the aircraft, so the faster the aircraft, the greater the lift the aircraft gets, and the higher it will fly. Also, lift and angle of attack have a lot to do with hunger.

Precautions when taking off the aircraft:

When the plane takes off, due to the sharp change in the surrounding air pressure or the disturbance of the airflow, people are prone to tinnitus, dizziness, nausea and vomiting and other uncomfortable reactions.

When encountering these situations, be careful not to panic, the ears will hurt a little when taking off by plane, and there may also be tinnitus, this is because when the plane rises rapidly, the surrounding air pressure changes suddenly, our inner ear tissues cannot respond quickly, and the air pressure in the Eustachian tube is different from the air pressure in the outer ear, causing a temporary blockage.

These can be alleviated by swallowing saliva, and if you are really uncomfortable, you can prepare some chewing gum in advance and chew it on the flight to relieve the discomfort. In addition, pinching your nose and taking a deep breath can slow down vertigo.

In addition, if you encounter unexpected situations such as turbulence during the flight, you should follow the instructions of the flight attendant and do not act blindly.
