ABSTRACT:
A rotor blade extended radially from a hub, characterized by an elongated spar and a plurality of axially aligned shells pivotally mounted on the spar, each having an aerodynamic center located in trailing relation with the spar and supported thereby for simultaneous axial and angular displacement as centrifugal forces are applied thereto, and a pitch controller including a plurality of pivotal pitch limiting arms transversely related to the spar, each being characterized by a cam surface defined along one edge thereof, engaging in supporting relation a cam follower of a truck pivotally connected to a shell and supported thereby for pivotal motion about an axis coincident with a radius of said spar, and a push-pull link interconnecting the arms for imparting simultaneous pivotal motion thereto, whereby the angular relationship of the arms to the spar is varied for varying the motion of the trucks along the arms for thus limiting the pitch of the segments about the spar.
