Title: Propeller pitch change actuation system

Abstract

An apparatus is described for adjusting the pitch of a variable pitch propeller blade characterized by: an actuator for setting the pitch of the propeller blade the actuator having; a rotatable screw for setting propeller pitch, a nut mounted for longitudinal motion along the screw as the screw is rotated, means for connecting the nut to the propeller blade to adjust the pitch of the propeller blade as the screw rotates, and a rotatable means mounted within the nut for locking the nut against longitudinal motion if the rotatable means is not rotating with the longitudinal motion of the nut and for allowing the nut to move longitudinally if the rotatable means is rotating with the longitudinal motion of the nut.
