Abstract / Hauptanspruch
A blade angle feedback assembly (200) for an aircraft-bladed rotor (130) is provided. The rotor is rotatable about a longitudinal axis (A) and having an adjustable blade pitch angle. The assembly comprises a feedback device (204) coupled to rotate with the rotor (130) with adjustment of the blade pitch angle, the feedback device (204) comprising a non-magnetically permeable body defining a root surface (304) and a plurality of magnetically permeable position markers (208) circumferentially disposed on the root surface (304), and at least one sensor (206) mounted adjacent the feedback device (204) and configured to detect a passage of the plurality of position markers (208) as the feedback device (204) rotates about the longitudinal axis (A).
