In fact, the wings of airplanes were modeled after the wings of birds from the beginning......

It can be said that biomimicry is the bridge between biology and technology.

Since ancient times, the natural world has been the source of various technical ideas, engineering principles and major inventions of human beings.

A wide variety of organisms have undergone a long-term evolutionary process that allows them to adapt to changes in their environment and thus survive and thrive.

Labor creates human beings.

Human beings, with their erect bodies, working hands, and the language of communicating emotions and thoughts, have promoted the high development of the nervous system, especially the brain, in long-term production practice.

As a result, human beings are incomparable in their abilities and intelligence far beyond all the taxa in the biological world. Human beings use their ingenuity and dexterous hands to make tools through their labor, thus gaining greater freedom in the natural world.

Human wisdom is not only limited to observing and understanding the biological world, but also using the unique thinking and design abilities of human beings to imitate living things, and increase their own skills through creative labor.

Fish have the ability to come and go freely in the water, so people imitate the shape of fish to build boats, and use wooden oars to imitate fins. Legend has it that as early as the Yu period, the ancient working people of our country observed the fish swimming and turning in the water with the swing of their tails, and they set up wooden oars on the stern.

Through repeated observation, imitation and practice, it was gradually changed to an oar and rudder, which increased the power of the ship and mastered the means of making the ship turn. In this way, people can make boats sail freely, even in rough rivers.

Birds spread their wings and fly freely in the air.

According to the record of "Han Feizi", Lu Ban used bamboo and wood to make a bird, "it flew into it, and it did not fall for three days".

However, people wanted to imitate the wings of birds so that they could fly in the air, so someone designed and built an ornithopter, the world's first man-made flying machine.

The above inventions and attempts to imitate the structure and function of living organisms can be regarded as the pioneer of human bionics and the germ of bionics.

The study of insect behavior is too late.

400 years after Leonardo da Vinci researched bird flight and built the first flying machine, people finally invented the airplane in 1903 after a long and repeated practice, so that mankind realized the dream of flying into the sky.

Thanks to continuous improvements, 30 years later, human airplanes have surpassed birds in speed, altitude and flight distance, demonstrating the wisdom and talent of human beings. But as they continued to develop a faster and higher aircraft, the designers ran into another problem: the phenomenon of flutter in gas dynamics.

When the plane flies, the wing vibrates harmlessly, and the faster it flies, the stronger the flutter of the wing, and even breaks the wing, causing the plane to fall, and many pilots who have tested the flight have lost their lives.

Aircraft designers spent a great deal of effort researching the elimination of harmful flutter, and it took a long time to find a solution to this problem.

A weighting device is placed on the far end of the leading edge of the wing, which eliminates harmful vibrations. However, insects have been flying in the air for 300 million years, and they are no exception to the dangers of flutter, and after a long period of evolution, insects have successfully obtained ways to prevent flutter.

When biologists studied dragonfly wings, they found that above the leading edge of each wing there was a thickened area of dark skin—a wing eye, or wing nevus. If you remove the wing eyes, the flight becomes swinging.

Experiments have shown that it is the keratinous tissue of the wings that makes the dragonfly's wings free from the danger of flutter, which is similar to the masterful invention of the designer. If designers first learn the function of wing eyes from insects and obtain design ideas that are beneficial to solving flutter, they can avoid long-term exploration and human sacrifice.

In the face of the winged eyes of the dragonfly's wings, the aircraft designer has a great feeling of hating each other!

Biomimicry is a discipline that is both old and young.

People study the principles of the structure and function of living things, and invent new equipment, tools and technologies based on these principles, and create advanced technologies suitable for production, study and life.

Long before the appearance of humans on Earth, various organisms have lived in nature for hundreds of millions of years, gaining the ability to adapt to nature in their long-term evolution in the struggle for survival. The study of biology can show that the extremely precise and perfect mechanisms formed by organisms in the process of evolution give them the ability to adapt to changes in the internal and external environment.

The biological world has many fruitful abilities.

For example, biosynthesis in the body, energy conversion, information reception and transmission, recognition of the outside world, navigation, directional calculation and synthesis, etc., show the incomparable superiority of many machines.

The smallness, sensitivity, speed, efficiency, reliability and immunity of the creatures are truly amazing.

For example, a dragonfly vibrates through its wings to create locally unstable air currents that are different from the surrounding atmosphere, and uses the vortices created by the air currents to raise itself.

The dragonfly can soar with very little thrust and can fly not only forward, but also backward and left and right, and its forward flight speed can reach up to 72 km/h.

In addition, the dragonfly's flight behavior is simple, relying on only two pairs of wings to flap constantly.

Scientists have successfully developed a helicopter based on this structural basis.

When flying at high speed, the aircraft often causes violent vibrations, and sometimes even breaks the wings and causes plane crashes.

Dragonflies rely on weighted wing moles to fly at high speeds, so people imitate dragonflies and add counterweights to the wings of airplanes to solve the tricky problem of vibrations caused by high-speed flight.

The conscience of heaven and earth, Han Xiao really wanted to create a pair of double magic weapon wings for the nine-headed golden snake and these war beasts, so that they could also fly, and change from the "army" to the "air force" that could fly in one fell swoop.

However, the wings of birds have advantages and disadvantages, and the wings of insects are the same.

After years of evolution, they have been optimized, but what is suitable for them is not necessarily suitable for humans or beasts.

Bionics pays attention to taking its essence and discarding its dross, in addition, it is necessary to seek truth from facts, you can't see that birds and insects are vibrating wings to fly, so you have to make a pair of vibrating wings out as a magic weapon, right?

Flying, whether it is birds, insects, or humans, is fast, accurate, and steady. If you don't have stability, then what do you need to do with the wings, it's better to fly Edgeworth.

Therefore, once the magic weapon of the wing was launched, it shook the refining hall again. They hadn't thought before that a flying magic weapon could be refined into such a ......

To be honest, Tianjimen once had a kind of magic wings, which were created by combining refining, talismans, and tricks, but unfortunately they were not very useful.

Flying, once you fly a little faster, you can't do it, the vibration is terrible, the stability performance is too poor, and it is not as stable and fast as the flight of the imperial weapon.

Therefore, Tianjimen did not mass-produce such wings.

Now Han Xiao's magic weapon wings don't look as gorgeous as the magic weapon wings of the Heavenly Machine Gate, but it is practical and stable, and after installing it, it can fly easily and quickly without trembling and vibrating.

Moreover, the current pricing of the Tiangong Academy is not expensive, and if the disciples of the Spirit Sword Sect buy it at the Tiangong Academy with the sect token, they can also enjoy a 20% discount.

As soon as the wings came out, the Refining Hall sent someone to buy it as soon as possible, and then, researched it.

After researching, I was also helpless......
