   • 2013 July-August, Lee S. Langston, “The Adaptable Gas Turbine”, in American Scientist:

     Turbines have been around for a long time—windmills and water wheels are early examples. The name comes from the Latin turbo, meaning vortex, and thus the defining property of a turbine is that a fluid or gas turns the blades of a rotor, which is attached to a shaft that can perform useful work.

2. (aviation) The wing of a helicopter or other rotary-wing aircraft.
3. (meteorology) A type of powerful horizontal-axis atmospheric vortex generated by the interaction of strong winds with mountainous terrain.
