Airplane

Aerial vehicle heavier than air that is used to transport people or cargo. Action moves motoresde propellers or jet, and is supported by the effect of air resistance to certain hard surfaces.

The hombretrató since ancient times to imitate the flight of birds. He thought at first that it was enough to provide themselves with wings and devised machines that were called ornithopters.

None of them gave the desired result, and it was not until the mid eighteenth century who began to build machines capable of moving more air than the equivalent weight, achieving lift off the ground.

But the usefulness of these devices (balloons and airships) is limited. The history of aviation today is that of the aircraft heavier than air.

Fundamentally, the most modern equipment of this type are built based on the same elements that allowed the Wright brothers and Alberto Santos Dumont practical to make the first flight in early twentieth century: wings that support the weight of the aircraft and its cargo, and tail surfaces which serve to give balance and direction. Using appropriate controls are made to vary the position of some surfaces so that the device up, down or turn in one direction or another.



Without doubt the best invention of the century, and that every day has been changing and so has brought us amazing benefits. It is a quick and easy way to get to our destination.
