Controllable pitch propellers vary the angle of each blade to control the amount on thrust produced by the propeller. They contrast fixed pitch propellers which vary their speed, keeping the angle of the blade fixed. This video explores the controllable pitch propeller and shows you how they vary their pitch to provide thrust to the vessel they are powering.
