What inspiration does the wings of dragonflies bring to humans

Scientists took a cue from the dragonfly's wings and improved the wings of airplanes. When the aircraft is flying at high speed, the wings of the aircraft will "flutter", that is, the wings of the aircraft will vibrate involuntarily, and this harmful vibration will cause the tragedy of the wings breaking and dying. At a time when we humans are struggling with this problem, insects in nature have invented ways to combat flutter millions of years ago.

Black moles on dragonfly wings.

It's a masterpiece of this kind. Dragonflies have a thick, heavier brown patch on the side of their wings that keeps them flying steadily. Someone has experimented that if the black mole on the dragonfly's wings is removed, the dragonfly will swing around when it flies.

Therefore, according to the principle of dragonfly wing nevus, people also designed thickened parts on the wings of airplanes, so that the harm of flutter can be eliminated.

Since ancient times, humans have wanted to fly into the blue sky like birds. Scientists carefully studied the principles of bird flight, and finally invented the airplane in 1903. Thirty years later, due to the continuous increase in the speed of the aircraft, the wings often broke due to violent shaking, resulting in the tragedy of aircraft destruction and death.

It took a long, long time for humans to find a way to prevent such accidents from dragonflies. It turns out that at the end of each dragonfly's wing, there is a thick spot that is slightly heavier than the surrounding area, which is the key to preventing the wings from trembling. From the thick spots on the dragonfly's wings, a way to prevent accidents was found, and a new type of aircraft with excellent performance was built and the flight quality of the aircraft was improved.

The inspiration was that "airplanes can fly, and dragonfly wings are the principle that airplanes can fly." ”

Dragonflies have two pairs of wings. It is a larger insect with longer wings, which are also narrower and membranous. It has very well-developed vision, with 3 monocular eyes and 1 pair of compound eyes.

The base of the hind wings of the dragonfly is slightly larger than the base of the forewings, and the wing veins are also slightly different, its larvae (larvae) generally live in water, but the life period is different from species to species, generally 2 years, and some will be as long as 3 to 5 years, it can be used to monitor environmental pollution, dragonflies are also known as dingding, lamp, and grasshopper.

Negative labor, multiplication, yarn sheep, mountain mi, light and light listening, etc.

Dragonfly habits

The eggs of dragonflies on aquatic plants are incubated larvae, which are called water flies.

It looks like a big-bellied spider, not very good-looking, not as cute as a dragonfly. On the lower jaws of the water fly, a pair of large pincers grow, and when it catches food under the water, it will stretch out these large pincers to make a surprise attack. The larvae of the mosquito are its best food.

Therefore, dragonflies have been experts in pest control since the larval age. It takes at least a year for the water to be in the water, and for a longer time, it takes seven or eight years to become an adult. When the water fly is about to feather, it will climb onto the branches of aquatic plants, do not eat or move, and is short and fat, less than one-third the length of the dragonfly.

Hello! The dragonfly's ability to fly is a revelation for human inventions.

One of the most famous is to improve the safety of aircraft flight according to the principle of dragonfly low flight, dragonfly relies on the nervous system to control the tilt angle, subtly adapt its flight speed to air pressure, and on the other hand, there are some spots on the wings of dragonfly, these spots effectively control the wings do not produce vibration and tremble, so that the flight becomes stable.

According to this, scientists applied this characteristic to the aircraft, and thickened some parts of the wings of the aircraft, which effectively solved the problem of flutter and ensured the safety of the aircraft.

Secondly, the entire fuselage of the aircraft is also made in imitation of dragonflies, so the inspiration of dragonflies to human inventions is very large.

Imitation of the wing mole, the thickened part of the wing is designed to ensure the safety of the fast aircraft.

Scientists invented the helicopter based on the dragonfly.

1. Scientists got inspiration from the wings of dragonflies and improved the wings of airplanes. When the aircraft is flying at high speed, the wings of the aircraft will "flutter", so according to the principle of dragonfly wing nevus, a thickened part is also designed on the wings of the aircraft, so that the harm of flutter can be eliminated.

2. Dragonfly, invertebrate, insecta, dragonfly, and suborder Paraptera. Generally large, the wings are long and narrow, membranous, and the reticulate wing veins are extremely clear. There are compound eyes, extremely sensitive vision, 3 in one eye; antennae 1 pair, thin and short; Chewing mouthparts.

Dragonflies are the insects with the most eyes in the world.
