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). Stockton Propeller employs the experts in propeller repair. 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).

If we look at a typical climb speed of 80 knots, we can see that the constant-speed propeller is delivering about 25% more power to the airplane than the fixed-pitch propeller. For a gross weight typical of a two-seat high … See more A fixed-pitch propeller being driven by a piston engine behaves very much like an automobile that has only one gear ratio in its transmission. The … See more A fixed-pitch prop is sensitive to variations in airspeed. Accordingly, the greater the variation in airspeed over the mission of the airplane, the harder it is to come up with an acceptable compromise pitch for a fixed-pitch propeller. … See more One of the parameters that determine how much power the propeller can absorb is the pitch angle in the blades.
