Flying bird swallow: Model for modern aircraft

Scientists have demonstrated how the swallow swallow changes the shape of its wings to improve its flying ability. Thanks to that, it is possible to help aircraft manufacturing engineers very much in their work.

Ten scientists from Wageningen University (Netherlands) and Lund (Sweden) have shown how flexible the swallow swallow is thanks to its wing structure. Their research shows that if the aircraft has wings like a swallow, it can improve its performance by up to 3 times.

The swallowtail (Apus apus) is one of the best flying birds . They often flap their wings instead of gliding due to the support of the air. Swallowing birds use almost all of their time in the air: hunting, couples and even sleeping while flying. On average, throughout the life of a bird, the flight of the swallow runs over 4.5 million kilometers, equivalent to six trips to the moon and back, or about . 100 times around the Earth.

Scientists looked at 15 wings of dead swallow swallows from protected areas. They put them in a wind tunnel and changed their direction to see the effect of their wings.

They found that flying slowly with extended wings helped the swallow's flight achieve the highest performance. But it is the wings with the gradual downward movement that produce better aerodynamic efficiency for fast and straight flight. That wing type also greatly facilitates the navigation. But in general, this wing is better because it is not easily broken like a wide wing.

Scientists also found that swallow birds can change the shape of their wings to increase efficiency when they want to fly in the air, or to divert faster.

The wings spread wide to help the swallow swallow at a slow speed, while the wing swept backwards to help them achieve higher speeds. The sudden swings in my direction required the wings of the wings to fall behind, because if the wings spread wide, they would be broken right under the force change so big. Moreover, the wing type is not shaken, and they can protect bone structure under high stress conditions.

Further studies show a harmonious combination of wings and each movement to help the bird fly over and over (no need to flap its wings) for up to 60% longer and the effectiveness of diversions increases three times.

In the airline industry people have paid more attention to the shape of the wings.

The most complete structure of the wings can enhance flight speed and thus, save fuel flights. NASA has relied on the swallow's wing structure to design a new type of aircraft with revolutionary wings. This tiny plane, just the size of a bird, took advantage of the benefits of changing the shape of its wings.

These aircraft are equipped with cameras and sensors, used in surveying and espionage, and designed in the same shape as real swallow birds and birds' flying movements. this.

Next scientists hope to be able to apply the advantages of this wonderful biological machine of nature to many times larger-sized drones. So far, throughout the development of the aviation industry, people are continuing to find ways to improve aircraft wings to achieve the highest efficiency.

Parallel to the effort to find ways to create new artificial compounds, nature also helps people to make many suggestions.
