The Basics of Airplane Propellers, Different Types and How They Work

A propeller with variable pitch can have a nearly constant efficiency over a range of airspeeds. [1] A shallower angle of attack requires the least torque, but the highest RPM, because the propeller is not moving very much air with each revolution. This is similar to a car operating in low gear. See more In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually … See more Three methods are used to vary the pitch: oil pressure, centrifugal weights, or electro-mechanical control.

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.

WebReducing MP one inch per minute is another good rule of thumb. When flying a fixed-pitch prop, avoid reducing power more than about 400 RPM at a time. Lycoming suggests we maintain at least 15 inches MP during a descent and set the propeller to the lowest cruise RPM position to prevent piston ring flutter.
