aerodynamics

aerodynamics extract from Britannica Online.

Branch of physics concerned with the forces acting on bodies passing through air and other gaseous fluids. It explains the principles of flight of aircraft, rockets, and missiles. It is also involved in the design of automobiles, trains, and ships, and even stationary structures such as bridges and tall buildings, which must withstand high winds. Aerodynamics emerged as a discipline around the time of Wilbur and Orville Wright's first powered flight in 1903. Developments in the field have led to major advances in turbulence theory and supersonic flight.
