A propeller protractor is an important software for any plane mechanic. It’s used to measure the pitch of a propeller, which is the angle at which the blades are set relative to the hub. The pitch of a propeller is important to its efficiency, because it impacts the quantity of thrust that the propeller produces. A propeller protractor can be used to measure the diameter of a propeller, and to examine the alignment of the blades.
Propeller protractors are usually manufactured from aluminum or plastic, they usually have a graduated scale that’s used to measure the pitch of the propeller. The protractor is positioned on the sting of the propeller blade, and the angle of the blade is measured relative to the protractor’s scale. Propeller protractors can be found in a wide range of sizes, they usually can be utilized on propellers of every kind. Some propeller protractors even have a built-in stage, which can be utilized to examine the alignment of the propeller blades.
