The term to whose plural is wings , can be used in different contexts. The concept refers to extremities which have certain animals to lift flight and remain suspended in the air. There are species with wings, however, that are not in a position to fly because of some of their morphological characteristics.
In the insects , the wings usually arise from the thorax. There are species that have a pair of wings, although others have two pairs. The dragonflies , the flies and the bees They are examples of winged insects.
The birds they also have wings, in this case usually covered with feathers . The variety of wings in these animals is very wide: swallows , the condors , the chickens , the penguins and the Eagles , to name a few species, they are all winged But they have many differences.
If we focus on the mammals , the only species that has wings and is capable of flying is the bat . Its wings are formed with a skin membrane supported by the fingers of the forelegs, with the exception of the thumb.
The wings are also the structures that allow the support of certain aircraft, such as planes . These wings obey the laws of aerodynamics and are essential for these vehicles to move through the air .
Needless to say, the wings of the aircraft are inspired by those of animals and insects, just as most human creations are based on the imitation of nature to raise his possibilities beyond what he had reserved for him. We shouldn't fly, or swim so deep or for days and months, but that didn't stop us from creating planes and boats, just two examples of the attitude of our species against natural limitations .
There is various evidence that the human being had dreamed of flying since the first time he saw a bird rise in the sky, and this leads us to prehistory. Whether through ancient myths and legends, among which we can discard the flight from the Greek Icarus, or from inventions that sought to remain in the air, something that geniuses like Leonardo da Vinci sought, it was already in our DNA to go beyond the surface of the Earth, and for that we needed wings.
Leonardo da Vinci had a special fascination with birds, and this can be seen in several of his creations, such as his ornithopters, a series of machines flying which he designed for the transport of several people, with one or two levels. Among his various concepts was one in which the pilot had to stand and another in which he had to lie down to drive the aircraft.
Despite the advanced vision of the great Italian inventor in his time, the ornithopters were not destined to take off, as they presented a fundamental failure: his engine was the same pilot , and no human being can generate with his limbs the energy needed to fly. The wings were designed in the image and likeness of the natural ones, but we must not forget that the birds they have hollow bones and, therefore, much lighter than ours, not to mention that they are born prepared to propel themselves into the air.
In the field of architecture , wings are called attached bodies which are located on the sides of the main building, being separated from it. This idea can also be applied to other human products, to refer to any thin protuberance located on the sides of the basic structure.
When wing is accentuated in the second TO (To ), this is the Arabic word used to refer to God .
