Aerodynamics (shaping of objects that affect the flow of air or gas) is a branch of
fluid dynamics concerned with the study of forces generated on a body in a flow. The solution of an aerodynamic problem normally involves calculating for various properties of the flow, such as
velocity,
pressure,
density, and
temperature, as a function of space and time. Understanding the flow pattern makes it possible to calculate or approximate the
forces and
moments acting on bodies in the flow. The use of mathematical analysis, empirical approximation and wind tunnel experimentation form the scientific basis for
heavier-than-air flight.
