A Airplane, also known by the most popular term of use of airplane, it is an aircraft, that is to say, a ship that moves through the sky and the air and that is much heavier than the latter, which is why it can sustain itself by its own means.
Among its most salient features are the provision of a fixed wing, one or more engines and a cargo space, or failing that, for the permanence of passengers.
Basically the airplane works thanks to the aerodynamic force generated in its wings, with an ascending direction and is known as lift.
It should be noted that this force is generated as a consequence of the pressure difference between the upper and lower part of the wing and that directly produces the wing design.
Since ancient times, man was seduced by the idea of being able to fly and then, for thousands of years, he focused his efforts in order to achieve results in this regard. Although the road was slow and winding, various innovations were gradually achieved that allowed us to reach the technology that we have today and that allows us human beings to use the airplane to move around different parts of the world in a comfortable and fast way.
The first notable contribution in this regard was made in the year 1883, when John Montgomery made a controlled flight through a machine that weighed more than air: the glider.
The airplane can be monoplane (it only has two wings), biplane (It has fixed wings with two groups of these, some arranged on the fuselage and the other pair below) or triplane (It is also a fixed wing but has three groups of wings, which are arranged one above the other).
On the other hand, airplanes, depending on their use, are usually classified as follows: civilians (because they transport goods, passengers, fight fires, carry out some type of health or training activity) and military (They carry out the loading and transport of militias and weapons, among other military activities).
Historically, since its appearance, the airplane has been an instrument repeatedly used in the military field with various missions.
