The aerodynamics is the area of the fluid mechanics that is dedicated to analyzing the movement of the gases –Especially of the air- and the interactions that these engage with the bodies that move in them.
Within this framework, aerodynamics studies the forces that affect the elements that move in the gases. It is important to note that when there is a body in the fluid, a change in speeds and pressures of the gas particles, resulting in resistance and lift forces.
Knowledge of aerodynamics is often applied to the displacement of an aircraft for him air. As an adjective, in fact, streamlined and aerodynamic refer to the appropriate design to minimize air resistance.
Above all Body that moves through the air acts a force that is known as endurance. This force has the opposite sense with respect to speed: that is why it hinders the advance of the body.
It should be noted that the Aerodynamic profile of a body is defined according to its shape, when it allows it to take advantage of the forces that originate from changes in pressure and air velocities. A airplaneFor example, it must have an aerodynamic profile suitable for flying.
A wind tunnel, on the other hand, is one that is used to subject a body to the influence of controlled air currents. They are generally used Models to scale with the aim of knowing the aerodynamic behavior of the object.
