A propeller assembly has a plurality of propeller blades, and a pitch change mechanism including at least one motor. A drive input drives the plurality of propeller blades to rotate about a central drive axis. The pitch change mechanism is operable upon driving of the motor to move the propeller blades relative to the drive input. The drive input includes a drive input gear transmission to change a pitch angle of the blades when the blades are moved relative to the drive input by the pitch change mechanism. Further, a method of operating a propeller assembly to change a pitch angle is disclosed and claimed. |
