Claim 21:
22. A rotor blade pitch control system comprising:
a first rotor blade operatively configured to be driven about a central axis of rotation;
said first rotor blade rotatable about a first pitch axis;
a first pitch drive rotor operatively configured to be driven about said central axis of rotation independently of rotation of said first rotor blade about said central axis of rotation;
a first pitch follower rotatable relative to said first pitch drive rotor;
said first pitch follower and said first rotor blade coupled such that said first pitch follower rotates with rotation of said first rotor blade about said central axis of rotation;
said first pitch drive rotor, said first pitch follower and said first rotor blade coupled such that said first pitch drive rotor is operatively configured to be driven to control an angular displacement of said first pitch drive rotor relative to said first pitch follower about said central axis of rotation and thereby control a pitch of said first rotor blade about said first pitch axis.
