Rotational Speed


Rotational speed is the number of revolutions per unit of time around a fixed axis. In aviation, rotational speed is an important concept in the operation of aircraft engines and propellers. The rotational speed of an aircraft engine is measured in revolutions per minute (RPM) and is a critical factor in determining the power output of the engine. The rotational speed of a propeller is also measured in RPM and is important in determining the efficiency and performance of the propeller. Proper maintenance and monitoring of rotational speed is essential for safe and efficient operation of aircraft.
