Etymology
The word "aerodynamic" is derived from two Greek roots:
Meaning
Aerodynamics is the branch of physics that deals with the study of the motion of air and other gases, and the forces acting on objects moving through them. It is a subfield of fluid dynamics and deals with both internal flow (such as flow through a duct) and external flow (such as flow around an aircraft).
Origin
The term "aerodynamics" was coined in the early 20th century by the German engineer Ludwig Prandtl. Prandtl is considered to be the father of modern aerodynamics, and he developed many of the fundamental principles that are still used today.
Significance
Aerodynamics is a critical field in the design and operation of aircraft, rockets, and other vehicles that move through the air. It is also important in the design of buildings and structures that are exposed to wind loads.
