Dragonfly: The "king" of flying, scientists have been studying for decades, but have been unable to understand its technology

When people talk about objects that can fly freely, people generally think of birds and airplanes. Birds are small animals that are born with the ability to fly, and airplanes are our most outstanding inventions in modern times. in the infinite sky.

As a bird with the ability to fly, it is of course more capable of flying than the aircraft produced by people. Before that, biologists have studied the limit of bird flight and found that a bird weighing about 360 grams, It can fly more than 12,200 kilometers, and during this period, the bird did not do anything to stay, and immediately flew from the Siberia region of Ukraine to Canada. Really understand the limits of life.

If we talk about the method of flight, the dragonfly is the world's well-deserved first place. I firmly believe that everyone has heard a story when I was a child. The basic principle of the aircraft is that it is produced according to the flight of the dragonfly. Compared with the Qing Dynasty, the flight safety accident of the aircraft is high, and it cannot be as calm as the dragonfly.

Moreover, after scientific research, experts have shown that flying insects have already occurred tens of millions of years ago, so if we talk about the originator of flying, of course, it belongs to the dragonfly.

Many people also disagree that dragonflies are the microorganisms with the best flight method in the world, because we were very simple to catch dragonflies when we were young.

But people can catch dragonflies, not because dragonflies fly badly. If we make a simple comparison between the net weight of the dragonfly and the flight speed of other microorganisms, you will know how terrifying the flying ability of the dragonfly is.

The faster flight speed of a civil airliner is 1120 kilometers per hour, and the net weight of a civil airliner is very heavy, everyone knows that the flight speed of the Swift can reach 350 kilometers per hour, but its rest weight Only 50 grams.

As everyone knows, the dragonfly can fly at a speed of 50 kilometers per hour, but its rest weight is only less than one gram. If we expand the rest weight of the dragonfly by 50 times, then the flight speed of the dragonfly may reach 2500 kilometers per hour.

To understand that in this world, the flight rate of 2,500 kilometers per hour can be achieved, and the only thing that everyone knows about is the cannonball that can be guaranteed.

Not sure if you are surprised by this number? After all, this description is not appropriate, so let's make a specific comparison.

In nature, black-necked cranes often transfer. A black-necked crane can fly hundreds of thousands of kilometers during the entire transfer process. From this flight data, it can be seen that the flight method of black-necked cranes Already very strong.

However, a dragonfly with a rest weight of less than one gram can fly over 6,400 kilometers and cross the Pacific Ocean of China. If it comes to energy consumption, the energy consumption of dragonflies is undoubtedly much lower than that of birds.

And dragonflies also have a more reasonable flight method, that is, the flight backwards that ordinary microorganisms cannot grasp. It is precisely this professional skill that allows the dragonfly to make some difficult poses during fast flight, such as changing the current position without slowing down.

Therefore, when the dragonfly is flying, it does not need to brake at all. It only needs to open its own backward mode, and it can move forward and backward at will in mid-air.

The reason why the dragonfly has such a strong flight method is the complicated wing structure of the dragonfly. The dragonfly has four wings that can move freely, and these four wings are fully transparent, and the ultra-thin area is only one micron thick.

However, there are many persevering porous structures in its wings, which can block the cyclone and give a strong forward driving force. And this structure also makes the dragonfly's wings resistant to moisture and dirt.

Summary: According to the above example, I believe you can also accept that the dragonfly is the first flight with the most exquisite flying ability in the world! It is also precisely because dragonflies have such a powerful flight method. It allows people to get a lot of useful information from it. I firmly believe that there are many areas in the dragonfly that are worth learning and imitating. From a certain level, the dragonfly is everyone's flight teacher. what.
