Web@jwzumwalt: A constant-speed propeller is a subtype of variable-pitch propeller (as the blade pitches of a constant-speed propeller are not fixed to a single value). All constant-speed propellers are variable-pitch propellers, but not all variable-pitch propellers are constant-speed propellers. – Vikki Apr 4, 2024 at 3:19 Add a comment WebOct 27, 2014 · In a constant speed prop, the prop control lever basically changes the speed of the prop (it is not always running at the same speed as you indicate in your question, but rather once the speed is changed by the prop control lever, the governor keeps it at that speed).

Fixed-pitch vs. Constant-speed Pilots of America

WebMay 17, 2003 · Fixed-pitch propellers, which remain common on lower-performance airplanes, can be optimized either for best takeoff and climb performance (referred to as a “climb prop”), or for best speed (a “cruise prop”), but not both. A “constant speed” prop, by contrast, can be adjusted for maximum efficiency regardless of speed or engine power. WebToday, there are many types of aircraft propellers available. The simplest of these propellers is either the fixed-pitch or the ground-adjustable propeller. More complicated propellers include controllable-pitch and complex constant-speed systems (automatic systems).
