rotor

n. rotating part of a machine; set of rotating blades (like the airfoils of a helicopter)

ROTOR was a huge and elaborate air defence radar system built by the British Government in the early 1950s to counter possible attack by Soviet bombers.It was first proposed in the Cherry Report of 1949 which suggested that the 170 existing Royal Air Force radar stations be reduced to 66 sites and the electronics extensively upgraded and relocated into nuclear bunkers. Six R4 Sector Operation Control (SOC) centres provided overall control to a command hierarchy of bunkers, known as R3, R2 and R1 bunkers. Another 28 Anti-Aircraft Operations Room (AAOR) bunkers were built for control of anti-aircraft guns.
