Abstract

A blade pitch measurement apparatus comprises first means for providing an indication of the instantaneous angular position of the rotor relative to a reference location and second means for providing an indication of the passage of a tenon through a selected location about the rotor. A third means is operatively coupled to and responsive to the indications provided by the first and second means for providing an indication of the angular position of each tenon and for computing blade pitch. A method of measuring blade pitch is also disclosed.
