ABSTRACT:
A variable pitch mechanism for a propeller is provided which has a simplified design in which, during normal operation, all component parts rotate substantially as a unit. In one embodiment the range of available pitches is limited automatically when a propeller is rotating above a threshold rate. In one embodiment, an actuator, preferably non-integral with a driver, can be moved, using the driver, so as to rotate a propeller blade about its longitudinal axis. Preferably the blade actuator and driver rotate substantially as a unit about the rotation axis of the propeller assembly.
