Abstract
The device adjusts automatically the rotor propeller pitch by the action of the centrifugal force on each blade (14) against the predetermined action of a spring member (7). The blade (14) may be displaced axially in a housing (13) of a blade foot (2), said axial displacement inducing a rotation of the blade (14) about its axis to modify the incidence thereof through a screw (3) and a nut (4), one being integral with the blade foot (2) and the other one with the rotor shaft (0). In an extreme position, the device enables the automatic feathering of the propeller. The invention may be conveniently used in aviation and in wind turbines.
