Variable-pitch propeller (aeronautics) - Wikipedia
网页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 by the pilot.
Variable-pitch propeller (marine) - Wikipedia
网页In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers —those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft ...

Understanding Variable Pitch Propellers - Hartzell Propeller
网页2015年11月30日 · So how do variable pitch propellers work? It’s the aircraft’s propeller that is the source of thrust that moves a plane forward. Propeller-driven aircraft moving at varying airspeeds must have adaptable propellers so that the blades don’t stall with the varying thrust and airspeed of the aircraft.
