Abstract

The present invention relates to a rotorcraft rotor () having a plurality of blades () movably mounted on a hub () via blade roots () that are respectively associated therewith. The rotor () is fitted with an information capture appliance having at least one measurement assembly (E) comprising a flexible bar () interposed in engagement at its respective ends between the hub () and a blade root () that is allocated thereto. A strain gauge () formed of a SAW transducer is implanted on the bar () and generates information relative to the bending of the bar () following tilting orientations of the blade root () in flapping (B) and/or in lag (T).
