How does the plane stay balanced in the air?

The emergence of aviation is one of the great technological evolutions of mankind. The creation of the airplane was a great landmark for history, as it significantly reduced travel time between two cities. For example, to travel from Ouro Preto to Rio de Janeiro was spent about 12 days, today with 50 minutes it is possible to carry out the same route.

The plane originated with a Brazilian of French descent, named Alberto Santos Dummont, who had his life invaded by the dream of flying. Not only he, but also the American brothers Wilbur and Orville Wrigh realized numerous flight experiments, trying to make an object heavier than air could fly. However, at that time there were already some vehicles, such as balloons and zeppelins, which could be placed above the clouds based on the principles of Archimedes, but they did not have the autonomy to fly, they did not satisfy the dreams of the man by numerous reasons like , for example, the fact that it can not completely control the fate of the flight of these vehicles. It was on October 23, 1906 that Alberto S. Dummont presented a rustic aircraft to a judging commission, the 14-Bis, thereby marking the origin of aviation.


But how can a vehicle, being heavier than air, fly? When in the air the plane does not fall because there are forces acting on it, counterbalancing its weight but as the weight is directed down the force that balances it in the air is directed upwards. What makes an airplane not fall is actually its speed and its wings.

The wings of an airplane are designed and constructed so that they cut the air. When the plane is in motion its wings cut through the air, causing the velocity of the air passing over the wing to be greater than the velocity of the air passing underneath, thus giving rise to a force from the bottom up balancing the airplane. That is, the air pressure at the bottom of the plane is higher than at the top, pushing the plane up, it is that force that holds it in the air. So the larger the weight of the plane the greater its speed should be so that it can take off and keep in balance in the air.
