rotor (plural rotors)

1. A rotating part of a mechanical device; for example, in an electric motor, generator, alternator, or pump.
   • 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.
   • 2001, National Transportation Safety Board, “1.7.1 Observations and Forecasts”, in Uncontrolled Descent and Collision With Terrain, United Airlines Flight 585, Boeing 737-200, N999UA, 4 Miles South of Colorado Springs Municipal Airport, Colorado Springs, Colorado, March 3, 1991‎^[1], archived from the original on 22 January 2021, pages 30–31:

     A glider instructor, who had been in the COS area for more than 25 years, was interviewed. He stated that around 1200 on the day of the accident, he observed a rotor hit the ground with estimated wind speeds of 70 to 80 miles per hour.

4. A quantity having magnitude, direction, and position.
5. (cellular automata) The set of cells within an oscillator that switch between being alive and dead over the course of the oscillator's period.
   • 1997 November 30, David Bell, “Day & Night - An Interesting Variant of Life (part 2/5)”, in comp.theory.cell-automata‎^[2] (Usenet):

     The following figure shows examples of the most versatile class of these oscillators. The first emulates the p10 shown above; the second has period 62 and a rotor of size 10.

   • 1998 March 18, Gunnar Johnsson, “Genetic aspects of the Game of Life.”, in comp.theory.cell-automata‎^[3] (Usenet):

     The problem of determining the asymptotic colouring for a cyclic pattern from a given initial black and white pattern is completely solved. The analysis leads to the proposal of the distinction between primary and secondary rotor cells (i.e. a refinement of the classical stator-rotor distinction).

   • 2008 June 25, Dave Greene, “Life: B37/S23 - A Chaotic Universe.”, in comp.theory.cell-automata‎^[4] (Usenet):

     In B37/S23, it goes symmetrical after 10 ticks, and produces a familiar pair of B-heptominoes after 23 ticks (the next generation after this can be found in the rotor of a standard B3/S23 p46 oscillator):

6. An amusement park and carnival ride consisting of a rotating cylindrical chamber in which centrifugal force adheres riders to the wall as the floor drops away, creating a sensation of defying gravity.

• main rotor
• tail rotor
• wound rotor

• stator
