[Advanced GUIDE] Propeller Basics

Definitions First it is important to understand the following definitions when talking about propellers: Blade / Pitch angle - This is the angle between the propeller plane of rotation and the chord line of the blade. On a fixed pitch propeller this angle is fixed, on a Constant Speed Propeller (CSP), this angle is adjusted to balance engine power and propeller power absorbed, controlling the propeller RPM. Washout or twist - The blade angle on a propeller blade is not the same along the w…
