Aerodynamics

Aerodynamics is the branch of studies that seeks to understand the forces that fluids exert on bodies that are immersed in them, be they sailing boats, automobiles, airplanes, whatever the body that moves in the air. Scientists study aerodynamic forces, such as lift and drag forces, because they affect both static and moving bodies, using their principles to design means of locomotion, such as automobiles capable of reaching high speeds. Studies on aerodynamics were of total importance for the construction of the first airplanes, and currently the aeronautical industry uses the principles of aerodynamics to build any type of airplane, but the use of the principles is not restricted only to the construction of airplanes and cars,

An important application of aerodynamics is found in the wings of airplanes and the airfoils of cars. In airplanes, the wings are designed so that the air flow at the bottom is smaller, thus causing a difference in pressure that ends up creating a lift force from the bottom up, which makes the plane lift in the air. In the wings there are still several smaller parts that if moved can cause the plane to change its trajectory, gain or lose speed and even increase or decrease its altitude. In cars, particularly racing cars (F1), the airfoils are also designed so that the cars are “glued” to the ground when at high speeds.

Designers as well as engineers use the principles of aerodynamics in order to improve the performance of bodies, both mobile and static. Aerodynamics is the part of engineering that studies fluid dynamics.
