The propeller speed is relatively low, at about 90 revolutions per minute, although it depends on the size of the propeller.

He throttled back the propeller speed to idle, and glided in.

A stroboscope synchronized with the propeller speed "freezes" the cavitation bubble.

This resulted in her being only able to only steam in a large circle until some directional control was achieved through varying propeller speeds.

Propeller Control - Used to set the desired propeller speed.

Within the series, the propeller speeds of all the plane characters have varied over the years.

The need for an efficient thrust block became even more important with the advent of steam turbines and their higher propeller speeds.

The engine was also run faster, and an epicyclic reduction gear was designed to keep the propeller speed below 1,100 rpm.

Variation of propeller speed in either direction was achieved by changing the turbine speed.

This gave her a low propeller speed while keeping a high turbine speed.
