What principle is the plane designed on? Is it related to birds?

Many people will be surprised when they see an airplane flying in the sky, it is so large and made of some metal, it is really incredible to be able to fly in the sky. Do you know how the plane was designed? Is it related to birds?

First, the design principle of the aircraft.

The design principle of the aircraft is modernAerodynamicsThe airplane uses the pressure difference caused by the different air velocity on the upper and lower surfaces of the wings to gain upward momentum, so the airplane must have a certain speed if it wants to fly. So we often see a long runway at the airport, and the plane has to taxi on the ground for a while before it can gain the power to fly, and then it will soar into the sky and take off. Without this runway, the desert plane would not be able to fly, so the design principle of the aircraft is different from the flight principle of birds.

The principle of bird flight is to create lift by flapping its wings to make the air flow to the back and down behind it. So birds can fly in place, while airplanes have to taxi for a while before they can fly.

2. Is there a relationship between airplane flight and birds?

We often hear that the design of airplanes is modeled on the form and principle of birds, so does the ability of airplanes to fly really have anything to do with birds? In fact, the design principle of the aircraft is not the principle of bird flight, but it does have a certain relationship with birds. The design of the airplane really learned a lot from the birds, especially the scientists who originally designed the airplane, and they took a lot of inspiration from nature.

Not only birds, but also the design of the aircraft took some design inspiration from animals such as tuna, dragonflies, bats, etc., and scientists studied the movements and techniques of these creatures in detail before finally designing the modern aircraft. For example, scientists studied the wing structure of birds, analyzed their feather distribution and structure, and designed the wings, fuselage, tail and power plant of the aircraft.

3. Summary. In general, the principle of airplane flight is different from the principle of bird flight, but scientists do learn a lot from birds to be able to design the existing aircraft. In fact, this kind of thing happens all the time, and many modern scientific products are inspired by nature.

The aircraft is designed according to the principle of atmospheric pressure, as well as the principle of the power plant. It has a certain connection with birds, and it is also designed by the thinking triggered by birds.

It doesn't matter, it is mainly designed according to aerodynamics, and the upward force is generated by the air flow up and down, and it also makes use of Bernoulli's principle.

It is designed according to the principle of generating air pressure according to the nature of the power plant, as well as the aircraft, and it is very difficult to design. It has something to do with birds.

The aircraft is derived from the Wright Brothers' Flying One. They learned how birds fly, integrated the mechanics of bicycles, built their own wind tunnel equipment, and conducted extensive experiments to collect more and more accurate data than their predecessors to design more efficient propellers and wings. Bird is a tool that operates according to mathematical principles.

What humans need to do is build a machine that can replicate its every move. Airplanes do learn a lot from birds, especially the pioneers of aviation history, who took more scientific and technological inspiration from nature. The fuselage of the plane was tuna, which was inspired by ornithopters from bats and dragonflies, and Lilindahl was inspired by storks.

Only with the scientific method can man fulfill his dream of flying. Many sketches of birds, bats and dragonflies were made, and their flight maneuvers and techniques were studied in detail.

The wing structure of birds was studied, and the distribution and structure of feathers were analyzed. The aircraft consists of five main parts, the wings, fuselage, tail, landing gear, and power plant. The flight of the aircraft depends on the ascent and the advance.

The forward movement depends on the forward traction resulting from the rotation of the propeller driven by the engine power or the forward thrust generated by the jet. The ascent is based on Bernoulli's principle, which states that the greater the velocity of the fluid, the greater the pressure, and the lift is closely related to the angle of attack. There is a rule on the carriage of liquids on board, but each bottle does not exceed 100ml.

Liquid toiletries are registered, lithium batteries cannot be registered. You have to carry it with you, or you have to open the case to get the battery. Don't bring contraband and hidden lighters.

The X-ray machine at the airport is very powerful, and the consequences of being caught are very serious. The use of power packs on board the aircraft is not permitted. There are many cases of power bank fires, so don't be lucky and follow the command of the crew, as it is also about your own safety.

Do not move if there are red signs on the aircraft, such as emergency doors and windows, life jackets, and other emergency equipment. Just know how to use them. If you move the emergency door, you may lose more than $100,000 and be detained.

The principle of aircraft design is the principle of modern aerodynamics. If an airplane wants to fly fast, it needs to have a certain speed. It's not the same as how birds fly.

It is designed according to the principle of physical aerodynamics, and the plane also has a certain relationship with birds, which imitates the shape of birds.

The airplane is designed according to the principle of aerodynamics, and it is also related to birds, and it is imitated by the shape of birds.

The airplane's wings and flight principles are borrowed from the bird's principle of flight.

More than 1,900 years ago, some people in China tied bird feathers together and made them into wings, which could glide more than 100 paces away. More than 400 years ago, the Italian Leonardo da Vinci designed a flying winger based on his observation and research of birds, trying to flutter and fly with the movement of his pedals.

Later, after many scientists' experiments, people figured out the mechanism of bird fixed-wing gliding, and realized that the wing must be like a bird's wing with a thick leading edge and a thin trailing edge, forming a curved surface to generate lift, coupled with the industry to provide lightweight metal materials and high-power engines, and finally invented the airplane in 1903, realizing the ideal of thousands of years of human desire to fly into the sky.

The development of the airplane originated from.

The anthropogenic yearning for flight and the study of birds, the ancient Du people did not understand the dynamics of aerodynamics, but imitated birds from the appearance, there are similar descriptions in the historical records of various civilizations, in Greek mythology, the son of Daedalus fled from Crete with his father, he flew too close to the sun, and the wings made of wax and feathers melted and fell into the sea after being heated. In modern times, due to the development of aerodynamics and mechanics, people gradually understood the principle of bird flight, because of 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 flowing through the lower surface, resulting in the upward air flow pressure on the lower wing surface is greater than the downward air pressure on the upper wing surface, this pressure difference is the lift, and thus the aircraft was created (the Wright brothers' plane was the first aircraft that could be successfully flown successfully, and there were many attempts before this, but the flight effect was not good). During World War I, there was a rapid development of airplanes, and most of the aircraft at that time were propeller engines, which were relatively slow and mostly had wooden fuselages.

After World War II, due to the advancement of engines, engines such as turbojets, turbofans, etc., appeared, and today civil aviation is basically monopolized by Airbus in Europe and Boeing in the United States.

The airplane was not invented based on a certain bird, since ancient times, human beings have imitated the flight of birds, such as Leonardo da Vinci's ornithopter, and the birth of the airplane is inevitable after the development of theory and mechanical power to a certain extent, it is not born by a whim of a person observing a certain bird at a certain time.

I can't talk about the specific kind of bird. Source.

Aircraft are not only bionics, but also aerodynamics derived from the study of bird flight. The bird uses its wings to flap to generate vortex air pressure, and the air pressure is lifted downward, and the air pressure is backward and downward, gaining forward momentum! (There are some similar forces and reaction forces, but the force must act on the object, as in the case of birds, in the air) Other examples include:

1. Use the characteristics of bird claws: bird claws are grasped when they are relaxed, and their claws are opened when they are forced, and related minimally invasive medical tools are invented by using this characteristic, and the forceps used for gallbladder removal in gallstones are this principle; 2. The principle of gliding with bird wings: gliders, parachutes, etc.; 3. Using the characteristics of the digestive system and rectum of birds, the aerial seeding technology was studied, which has not yet been used in China.

The airplane was invented by obtaining the principle of the difference in pressure between the upper and lower surfaces of the wings when the bird flies and generates the lifting force, which is physically called Bernoulli's principle.
