Pitch

Pitch

Pitch is one of the fundamental characteristics of a propeller used to designate its size. Props are usually sized by their diameter and their pitch. Pitch is the angle the blade makes relative to its plane of rotation. Pitch isn’t actually the angle itself. As a result, the prop acts somewhat like a screw being driven into a solid material. As it turns it moves forward. How far is determined by the pitch. Therefore, pitch is represented as the distance the prop would travel forward in one rotation, measured in inches.
