For a plane to fly, it is necessary that some kind of force can win or your weight, then let’s check on this page what actually happens physically when he is moving, giving rise to phenomena which will be explained in the unfolding of this story, in which the wings, also called Airfoil will be object of study. Aviation is based on the principles of physics, some studied at school, in explaining all the mysteries that revolve around this practice. Often, when people see for the first time a Boeing or an Airbus taking off or landing at an airport, you have no idea how that machine with a few tons can stay away, meters and kilometers. For these reasons this matter becomes very curious and sometimes passionate.
We know that the main obstacle in the first attempts to put a plane in the air was its weight, a force caused by gravity, but with some different formats on aerodynamics of bodies, to control this problem, by hand at first. In studies and research done by scientists from various eras, it was found that the air, fluid that will be responsible to support an aircraft in flight is composed of some elements, including nitrogen, oxygen and water, this may change in variables such as density, temperature and pressure. These changes in the atmosphere are related between temperature and pressure differences between the different masses of air circulating, causing displacement of the layers, beginning to the winds, which may be useful or detrimental to flight.
The vector and scalar quantities are present in this matter, being all vector forces, including the gears, pressures and accelerations, the scalars, composed of the mass, temperatures and densities. When a plane has the favorable wind, we have a vector sum, or vice versa, with this, the vectors are widely used, giving rise to all sorts of arising, whether they are vertical, as weight and support, that will be seen later in the article, or horizontal forces, such as traction and air resistance, when the plane is in flight with constant speed , the sum of all forces is zero. The hydrostatic thrust, seen in, is also well used, but having as fluid, air, because the displacement of air backwards will cause a force forward, then the thrust, already relating to the third law of Newton’s law of action and reaction (to everything there is another of the same direction, same module and anticlockwise). The temperature is a scalar very important, being highly variable, we know that the higher we are in relation to the sea level, the lower its value, so does the density of the air, because the higher the altitude, the more rarefied changing related forces in flight, because changes directly to air resistance, as for the advancement of a body.
