WebFeb 16, 2024 · This is achieved through the work of a constant speed unit – a device which mechanically alters the pitch angle to maintain the RPM, using centrifugal force to balance out over or under speed. The beauty of this type of propeller, is that if the thrust is reduced, RPM is reduced accordingly, and the opposite if thrust is increased. WebA 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.
