How fast does a prop on a plane turn?

The rotational speed of a propeller on an aircraft typically ranges from about 1,500 to 3,000 revolutions per minute (RPM), depending on the type of aircraft and its design. Smaller general aviation aircraft may have propellers that turn at lower RPMs, while larger or more efficient turboprop engines can operate at higher speeds. The blade tip speed can reach around 600 to 700 miles per hour, depending on the diameter of the propeller and the RPM.
