Abstract
An tiltrotor aircraft includes a rotor position control system (RPCS). The RPCS includes an electric motor configured to selectively rotate the rotor blade, a target marker kinematically associated with the rotor blade, a sensor configured to sense a position of the target marker, and a flight control computer configured to selectively control the electric motor in a normal mode of operation in which the rotor blade provides thrust and a phase lock mode of operation in which the electric motor maintains the rotor blade in a predetermined indexed position.
