Modern Dictionary of Aeronautical Engineering: Comprehensive and Illustrated Encyclopaedic Dictionary

Aeronautical Engineering is the branch of engineering concerned primarily with the special problems of flight and other modes of transportation involving a heavy reliance on aerodynamics or fluid mechanics. Aeronautical engineers design, develop, and text aircraft, spacecraft, missiles and supervise the manufacture of these products. Those who work with aircraft are called aeronautical engineers, and those working specifically with spacecraft are astronautical engineers.
