Aerodynamics

Aerodynamics Aerodynamics is the branch of dynamics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies in motion relative to such fluids. The Latin word for aero means air, and the Latin word for dynamics means power. Steady aerodynamics this term is used to describe situations where there is no rapid change in properties over time. For example, an aircraft cruising straight and level in the upper atmosphere, well above where any gust can reach it. When such situations are being analyzed, a lot of effort can be saved by neglecting terms in the equations, which describe rates of change of the flow properties or forces at any point on the aircraft. Time-accurate strong-interaction models for the coupling of a boundary-layer method with a method for three-dimensional, unsteady, compressible potential flow about elastically deforming wings are developed. The investigation of the flow behind on oscillating airfoil has shown that two waves of convected vortices can be distinguished: One wave convected at, roughly, the outside uniform velocity; and an inner wave in the core of the wake originating at the trailing edge which is convected at a much lower speed.
