It is a tool used to manualy change the pitch of an variable pitch aircraft propeller.
"Pitch" is a term most commonly used when referring to propellers. The pitch of a propeller is the distance the propeller would move in one rotation, if it were moving through a soft solid. Similar to a screw moving through wood.
An azimuth thruster is an engine and ship's propeller in a pod which is azimuth adjustable.
12 is the diameter 14 is the pitch
An azipod is an azimuth thruster, an engine and ship's propeller in an underslung pod which is azimuth adjustable.
Variable pitch propeller

A screw's pitch is the amount it moves forward per turn. An airscrew (propellor) pitch is the same concept.
The pitch of the propeller causes this noise.
if the RPM is the same the 14 would be the fast es
