R stands for which term?

Explanation:
R stands for Rotorspeed. In contexts involving rotating components, letters like R are used as variable names to describe how fast the rotor is turning. This is a descriptive term for the rotor’s motion, not a size or a unit. Radius would refer to a distance from the center to the edge, which is about size, not speed. Rate is too general and could mean many different things. RPM is a unit (revolutions per minute) that tells you how fast something spins, but the term describing the concept is Rotorspeed.
