Abstract
A blade pitch control and protection system for a propeller includes: an actuator where displacement of said actuator corresponds to a change in blade pitch of said propeller; an electronic unit, a position control sensor configured to interact with said actuator. The position control sensor detects actuator position and thereby said blade pitch of said propeller, and to send a control feedback signal to said electronic unit via a first channel, based on said blade pitch, and a protection sensor configured to interact with said actuator, configured to detect actuator position and thereby said blade pitch of said propeller, and to send a protection feedback signal to said electronic unit via a second channel, based on said blade pitch. The electronic unit is configured to, based on said control feedback signal, control movement of said actuator to alter said blade pitch through a control command.
