WebMar 18, 2024 · 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 … WebMay 17, 2003 · The diagram below shows a cross-section of a typical constant-speed prop. Engine oil pressure against a piston in the hub causes the blades to move back from flat pitch. The pressure is regulated by a propeller governor (not shown). When the prop reaches the desired speed, the governor opens a valve, reducing oil pressure to the piston.

"WebOn a variable pitch prop, it changes, as you have correctly stated, the pitch of the prop. That will only change the RPM of the prop, NOT of the engine, which is what the RPM gauge is measuring. Basically you set the RPM of the engine using the throttle and then set the efficiency of the prop by using the prop pitch. Some airplanes do this for ... " - Boldmethod variable pitch prop
